Main features of fluid bed dryers
Fluid bed dryers are widely used in various industries for efficient drying of granular, powdered, or crystalline materials. In this article, we will explore the advantages of fluid bed dryers and their significance in industrial drying processes.
One of the primary benefits of fluid bed dryers is their ability to achieve uniform drying of materials. The fluidization process involves suspending particles in a stream of air, ensuring consistent contact between the heated air and the material particles. This uniform exposure to the drying medium promotes efficient moisture removal and prevents over-drying or under-drying of specific areas. The result is a homogenous and consistent final product with controlled moisture content, essential for industries such as pharmaceuticals, food processing, and chemicals.
Fluid bed dryers are designed to maximize heat and mass transfer between the drying medium and the material being dried. The fluidization process creates a turbulent environment that breaks up particle clusters and exposes a larger surface area to the drying medium. This increased surface area allows for faster and more efficient moisture evaporation, reducing drying time. Additionally, the uniform distribution of heat throughout the fluidized bed ensures consistent drying across the entire material mass. The enhanced heat and mass transfer capabilities of fluid bed dryers contribute to improved drying efficiency and overall productivity.
Fluid bed dryers are recognized for their energy efficiency compared to other drying methods. The fluidization process requires lower temperatures to achieve effective drying, resulting in reduced energy consumption. Additionally, fluid bed dryers are designed with heat recovery systems, where the heated air leaving the dryer is recirculated and preheated before entering the drying chamber again. This heat recycling minimizes heat loss and optimizes energy utilization. The energy efficiency of fluid bed dryers not only lowers operational costs but also aligns with sustainability initiatives by reducing environmental impact and carbon footprint.
Fluid bed dryers are highly versatile and can accommodate a wide range of materials and applications. They can effectively handle different particle sizes, shapes, and densities, making them suitable for various industries, including pharmaceuticals, chemicals, food processing, and minerals. The drying parameters of fluid bed dryers, such as temperature, airflow rate, and bed depth, can be easily adjusted to meet specific drying requirements. Additionally, fluid bed dryers can be equipped with additional features, such as spray nozzles for granulation or coating, expanding their capabilities and providing a comprehensive solution for drying and processing applications.
Fluid bed dryers offer excellent scalability, allowing for easy adaptation to different production capacities. The fluidization process can be efficiently maintained across various sizes, ensuring consistent drying performance from laboratory-scale to industrial-scale operations. Furthermore, fluid bed dryers are equipped with precise controls for temperature, airflow, and product residence time. This enables operators to have precise control over the drying process and achieve the desired drying outcomes. The ease of scale-up and control provided by fluid bed dryers simplifies process optimization, reduces production variability, and enhances overall product quality.
Fluid bed dryers provide significant advantages in industrial drying processes, including uniform drying, enhanced heat and mass transfer, energy efficiency, versatility, and easy scale-up and control. Their capabilities make them an indispensable tool for industries seeking efficient and reliable drying solutions, facilitating improved productivity, and superior product quality.

Chapter 2: Why You Need Fluidized Bed Drying Equipment
Traditionally, you’d require much time and effort to dry your granules, especially for pharmaceutical purposes.
Therefore, there was need to develop better material drying equipment.
And after years of research, a fluid bed dryers were developed.
But, why do you need it?
· For Uniform Drying of Materials
It meant that you’d dry the grains in a tray, which unfortunately wouldn’t even yield consistent drying conditions.
You won’t necessarily have to worry about some particles containing more moisture than other after drying on this device.
It is apparently one of the reasons you need it since consistency in drying conditions also enhances the quality of the end product.
· Reduce Drying Material Drying Time

The point here is that it prevents you from what would sound like unnecessary processes trying to carry out these different tasks separately.
A good example is fluid bed dryer granulator and coater.
Obviously, you need to modify the fluid bed equipment a little to accommodate all these functions.
What do I mean here?
In traditional methods, it would be somewhat challenging to find a machine that you can use for heating, cooling, drying and coating all at the same time.
So you’d primarily hope from one machine to the other to complete all these processes.
And, that is the pain that the fluid bed dryer now relives you from – making it a necessity in the bulk processing industry.
Furthermore, you also need machine because in many cases, you tend to find the customized unit.

And that’s primarily the reasons that make acquiring this particular machine an ideal necessity for you.
Nonetheless, let’s now look at the different aspects revolving around the design and construction of fluid bed dryer in this next chapter.
Chapter 3: Fluid Bed Dryer Design and Construction
This equipment consists of numerous components assembled together to provide a continuous process in drying pharmaceutical granules.
The truth is:
It cannot complete the process without some of the parts which form a significant basis of the machine.
Here is an example of fluid bed dryer equipment:
Fluid Bed dryer equipment
And that’s why it is of more interest to understand all these components and the specific roles they play in making sure the process becomes a success.
Of course, we cannot discuss all the components of this machine.
But in this section, I will take you through some of the notable parts and explain them briefly to get a rough idea of what they entail.
Later on, we also find out some of the standard design options available for this drying equipment.
This is also essential as it helps you to get useful idea especially when it comes to shopping for one.
3.1. Main Fluid Bed Dryer Parts and Components
Our primary focus in this section is to discuss and understand some of the parts and components of the fluid bed dryer machine.
But before we look at these parts, it’s important to mention that different fluid bed dryers have a varying number of elements.
Some have more whereas other have a few.
It depends on several factors such as the specific design of the equipment, size as well as the need for additional requirements.
Comparing two types of fluid bed dryers
Nevertheless, they all serve the same purpose albeit to different extents.
So you shouldn’t necessarily worry that perhaps one with fewer parts would not be ideal for the task.
So let’s start straightaway;
· Product container
It is one of the most critical components of a fluid bed dryer.
In most cases, this part is often made of hard materials such as stainless steel to prevent it from wearing out faster.
You’ll find that an ideal product container somewhat takes a conical shape.
It is vital because this shape helps in enhancing better fluidization.
In most cases, it needs to have a plate that allows for air distribution to make it possible for the process to be efficient.
Product container for a fluid bed dryer
Moreover, the product container varies from one fluid bed dryer to the other depending on size.
And so if it is about the size factor, you need to ensure that you find the equipment that has ideal size for your needs.
· Control cabinet and panel
This component is equally crucial in this equipment.
It is the pillar that determines execution of all the processes in this machine.
Fundamentally, the control cabinet and panel allows you to send and receive process signals accordingly.
Its importance is that it makes it possible for you or any other operator for that matter to control all the parameters revolving around material processing effectively.
This equipment in computerized.
Therefore, the control panel enables you to merely click the appropriate button for a specific task.
Control cabinet for a fluid bed dryer
So this integrated control system is helpful in making sure that the quality of the product is consistent in meeting various specifications.
It is also essential since it helps in keeping you alert just in any case an unlikely event such emergency arises and requires immediate attention.
· Exhaust blower
An exhaust blower, in this case, refers to a component that this equipment uses in expending contaminated fumes and hot air away.
The role of this component is to allow you to breathe relatively clean air.
Substantially, the fumes and hot gas during material processing can prevent you operating the machine efficiently.
Some particles would also emit noxious gases that would chock you throughout hence making you quite uncomfortable.
See the position of the blower – Photo courtesy: Applied Chemicals
So the exhauster blower then plays a considerable role in making sure that such gases do not stay anywhere in the vicinity.
· Air preparation unit
Ordinarily, this unit refers to the system used in bettering the quality of compressed air which feeds into the fluid bed dryer.
This component helps in enhancing the flow rate of air which subsequently results to better air supply performance.
Air preparation unit
Mostly, this unit is ideal for this equipment as it makes it possible for it to control the flow of compressed air.
The air preparation unit often contains filters for getting rid of moisture in the compressed air.
Also, it comprises regulator for controlling air pressure getting into pneumatic systems.
Moreover, this component also has a lubricator which enables it to oil the moving parts and seals hence enhancing its overall lifespan.
· Spraying nozzle
This refers to a component that breaks the fluid flow apart into a spray pattern.
Different fluidized bed materials have different spray nozzles.
In fact, the specific type of application is what ideally determines the type of spraying nozzle the equipment will have.
But at the same time, you also need to know that this component plays an essential role in determining the quality of the final product.
In general, spraying nozzles come in different designs.
Pressure, rotating, airless and gas atomizing are some of the common spraying nozzle designs.
Fundamentally, you also need to understand that factoring in the variouselements when analyzing this component is critical.
So you need to be particular and analyze this fluid bed part in detail so that you can be certain that it indeed ideal for the application.
· Exhaust filter
This is primarily a component that helps in cleaning the filters which subsequently lead to improved processing yields.
In most of the fluidized bed dryers, they are often positioned just above the processing area.
Nonetheless, this could also vary depending on the design of the specific machine.

The exhaust filter is vital because it also enables a consistent product flow within the conical expansion chamber.
Now, this is significant because, at the end of it all, you’ll be able to attain the most homogenous and repeatable results.
· Air distribution plate
It is unquestionably one of the most fundamental components especially in facilitating the overall material processing.
In most of these machines, it is positioned at the lower side of the product container.
It is vital because it helps in distributing fluidizing air in between the internal and external partitions.
However, it is also vital to understand that air distribution plates come in different sizes and variations.
Of course, this also depends on the particular design of the machine.
But in general, the air distribution plate, especially for modern fluid bed dryers, are designed for cutting-edge technology.

What this indicates is that it helps in enhancing appropriate fluidization of the granules or powder hence providing best granulation results.
· Solution delivery system
In some instances, it’s also known as a liquid delivery system.
The primary purpose of this component is to help in making sure that the solution gets into the atomizer relatively smoothly.
It consists of a magnetic filter, a liquid tank as well as a pump.
All these are useful in improving the efficiency of this component and ensuring that it performs at optimum level.
When purchasing a fluid bed dryer, it is vital to asses this particular part so that you can be sure of getting the best material processing efficiency.
Ordinarily, the solution delivery system tends to dispense singular or multiple thin coatings efficiently in one pass.
Again, like any other components, this one also varies from machine to another undoubtedly depending on the application of each one.
· Heating system
It refers to a kind of heater that heats the granules during material processing.
Ideally, during processing, particles often tend to pass through the filter first before getting to the heater for heating.
The heating system typically consists of various components such as gas furnace and electric steam radiator heater among others.
The heating system is located inside stainless steel tubes in the bed of fluidized bed dryer.
Generation of heat within this system occurs relatively fast and efficiently.
It is always imperative to ensure that the heated air goes through a high-efficiency filter before it gets into the drying chamber.
This helps in a great way to get a pure and high-quality final product.
· Dust collector
It is also another significant part of the fluid bed dryer.
The dust collector ordinarily, helps in reducing wastes and emissions while at the same time complying with the policies revolving around the environmental air.
This component removes suspended dust from the ambient air.
Now, this is helpful in improving the indoor air quality as well as reducing the outdoor emissions.
In fluid bed dryer, this component also plays a fundamental role in dust from the water vapor.
It consists of several parts including dust packet, exhaust pipe, cone pipe and cylinder.
Again, remember that this still varies from one machine to another depending on the design and other factors.
In bulk processing, it is highly likely that you can recycle the dust collected from this component either as raw material or any other use.
This way, it reduces disposal costs and quantity of waste.
3.2. Fluid Bed Dryer Diagram
Essentially, the fluidizer bed dryers come in different designs, of course depending on a wide range of factors.
More importantly, several parameters determine the particular design of a fluid bed dryer. Some of these parameters include
- Heat transfer
- Efficiency, and compactness among others.
However, there is also a need for understanding that in many cases, the purpose and working principle always seem to be similar, design notwithstanding.
Nonetheless, it is essential to understand that the different designs play an enormous role when it comes to finding equipment that suits your needs precisely.
And it is the primary reason you’ll find most manufacturers designing your ideal fluid bed from unique materials such as stainless steel, Inconel among others.
There are also other aspects that make the design speciality stand out for particular material it’s meant to process.
For instance, the design for distributor plate in almost all of these types of the machine helps in ensuring even distribution of fluidizing gas across the bed’s surface.
Let’s compare just a few designs so that you may understand what I am talking about here:
SaintyCo fluid bed dryer
Fluid bed dryer granulator and coater
Another aspect regarding design is that in most of the machines, you hardly find one with moving parts that come in contact with the product.
What you need to know regarding the design option element is that they come in multifold.
You only need to determine what you probably think suits your particular needs.
Some of the various leading design options available for this type of equipment include;
i. Contact tubes and plates
ii. Explosion resistant design
iii. Recirculating contained gas design
iv. Stirred FBD
v. Multiple zones and stages
vi. Deep fluid beds
vii. Fully automated operation
viii. Integral drying/cooling
ix. High-temperature FBD
Now, with that in mind, let me take you a step further and see how this machine works.
Chapter 4: Working Principle of Fluid Bed Dryer for Drying Applications
Remember I promised you earlier about discussing the working principle of the fluid bed dryer machine.
And true to my promise.
This is the section we want to expound and know everything it entails.
Now, working principle, in this case inherently implies the manner in which this equipment functions.
In a layman’s language, it is the processes that this deviceundertakes in making sure that it dries up the pharmaceutical grains or any other particles for that matter.
But first, I want you to watch this video:
Also, have it mind that this working principle is specially for drying applications.
Of course, it is better to understand it since the principles might vary from one application to another.
Some terms would be a little bit technical.
Nonetheless, I will try to be as simple as possible, to ensure that you get the idea of what I’m talking about.
So let’s get straightaway to this concept:
Fundamentally, this equipment works on a principle of fluidization of the materials.
During this process, hot gas or air gets through the bed of compact particulates.
The gas then moves in the upward direction through the tiny spaces which are between these particles.
At this point, velocity increases, which in turn forces the particles to drag on upward direction on the granules at a stage which becomes equivalent to the force of gravitation that is underneath.
It then leads to fluidization of the bed which makes it possible for these granules to suspend in the fluid.
The fluid bed dryer consists of an electric motor which powers the fan inside it.
So what happens is that from the beginning of the process, the fan helps in sucking air inside from the surrounding.
This air gets extremely hot given that it transverses through a heating system inside the dryer.
It is this hot drying air that is forced to course through the bed which containing the moist particles put down on a continuously-vibrating perforated steel bed.
Now, the hot drying air gets into the bed with constant velocity and temperature that makes it possible for fluidization of the bed.
It happens that this pressure allows for intimate contact with every granule particle with the hot drying air.
The vibration or continuous shaking of the porous steel bed triggers the bed to carry the particles forward at a slow pace along the dryer’s dimension.
The hot air then sucks all the moisture present in granulates.
After that, it gets into the dust recovery system where it’s recycling takes place and for another purpose in the same process.
Ideally, what happens here is that as the flow of increases inside the steel bed, the more it enlarges and grains begin a turbulent motion.
So the constant contact with makes it possible for the material to get dry.
After that, the air that leaves this equipment passes through the filter to allow for the collection of fine granular materials.
It is possible to control the velocity and temperature of the hot air as they pass on the bed.
What this implies is that this machine can as well dry the extremely wet materials effectively.
The next thing that happens is feeding the dry material into the cooling zone the cool air lowers the temperature of the material to the specific required condition.
One fundamental aspect of the fluid bed dryer worth underlining more and more is that it has a high rate of drying materials, which also take the shortest time possible.
Thus in this manner, you can attain efficient drying of powder or product with the aid of a fluid bed dryer equipment.
Actually, the principle is as simple as that.
It, not rocket science as you try to imagine. Just basic concepts that if you use the equipment a few times, you’ll quickly notice.
Hopefully, the working principle of FBD is understandable.
If so, then let’s get to the next chapter and find out more about the parameters of this equipment and their effects on the end product.
Chapter 5: Fluid Bed Dryer Parameters & How theyAffect the Final Product
Here’s a fact;
To enhance fluid bed dryer’s efficiency, operation as well as reproducibility, there are quite a number of parameters that must be controlled.
Remember this is a technology which involves removal of a certain extent of moisture from the grain particles by fluidization process.
And so most definitely, this process has to also involve the parameters especially about gas flow and other constructional parameters.
In this section, we want to look at some of these parameters and discuss them to get a better understanding of their effects on the final product.
To start with, these parameters are categorized into three main elements;
Apparatus, Process and Product.
It is also essential to know that this categorization is helpful in ensuring better comprehension to control each parameter.
So let’s start with the apparatus parameters;
1. Air distribution plate
Fundamentally, there is a need of attaining desirable air flow within the desired temperature.
This is where the position of the air distribution plate becomes vital.
It’s positioning needs to be in such a manner that makes it possible for it to obtain the necessary airflow and heating temperature.
In any case, the air distribution plate is placed within a close range to the blower outlet, it is highly unlikely for the desired temperature to be attained.
So primarily, the positioning of the distribution plate, in the long run, helps in determining the pattern of the final product.
And that’s majorly why it is an important parameter worth controlling during the fluidization process.
2. The shape of the product container
This is also an essential parameter worth controlling.
You see, the fluid bed dryers tend to have different shapes.
Now, these containers help in holding the grain particles together while still in the process.
Given that temperature and velocity varies, it means that the shape of the container will certainly determine the shape and size of the end product.
In most instances, equipment with an annular based design will always provide a relatively better product.
So in general, it would be ideal to understand the particular shape of the instrument if at all you need to get the best results out of this process.
3. Type and position of the spraying nozzle
The kind of spraying nozzle and its positioning on this fluid bed dryer is also a critical aspect worth noting.
This is even more specific when it comes to using this equipment to coat the materials and not necessarily for drying.
The essence is that it helps in determining whether or not the solution will become dry fast before it reaches to the tablet.
Therefore, in any event, that you need the atomized solution for the coating to get to the granular, it would be necessary if the nozzle height is adjusted accordingly.
Those mentioned above are the apparatus parameters.
Technically they have an effect on the final product on the basis of the physical aspect of the equipment.
Now, let’s look at the second category which is processor operating parameters;
4. Pressure operation
The pressure operationaffects the final product both positively and negatively.
But ideally, the discharge of air via the blower should necessarily be at optimum level.
What happens is that in such cases, the moisture content available on the grain particles reduces comparatively fast when the pressure operation is higher.
Again, the high-pressure operation also makes the particles to fluidize easily.
This leads to the likelihood of comfortable carriage of mass and heat transfers.
Material from fluid bed dryer
Increase in pressure operation may also result to increase in the size of a bubble in the bed.
Nonetheless, the pressure operation is also quite concerned with elements to do with mass and heat transfer that takes place at the fluidized bed.
Another important aspect regarding this parameter is that it dominates the performance of the fluid bed dryer more than temperature does.
It is the other operating parameter of this equipment worth controlling.
The fact is that the inlet temperature is inversely proportionate to the duration of drying.
The resident temperature of the bed is the significant factor that determines the drying rate.
During the drying process, the air temperature also affects the moisture diffusion.
It happens that the particles tend to absorb more water at high temperatures than at lower temperatures.
Mostly, when temperatures are high, moisture diffusivity also tends to increase.
This then results in decreased drying time and increased drying rate.
This,therefore, increases the rate of evaporation.
It is also worth noting that the nature of material also plays a considerable role in determining the choice of operating temperature.
It is also an essential operating parameter of fluid bed dryer that plays an indispensable role during the drying process.
Similar to temperature, air humidity also has inverse effects on the drying process.
It should primarily be as low as possible if faster drying rate has to be achieved.
Additionally, the moisture present in the inlet air has extreme effects on temperature profile and rate of evaporation.
It is possible to reduce moisture from the particles by maintaining the particles diameter to be less.
This is because comparatively, large size particles tend to contain relatively long diffusional paths.
This is critical because it makes the internal resistance to prompt against bulk transfer.
So necessarily, faster rate of drying is attained when all the time the moisture content of the inlet air is maintained at its minimum.
7. Air flow rate
It is the third parameter in the operating category.
For efficientfluidization to take place, it is necessary to control air flow rate meticulously.
In general, achieving an efficient drying process requires mandatory optimization of the air flow rate.
What happens is that if the air flow rate is relatively fast, then chances are high the gas would not be heated to the necessary optimum level.
Again, if the flow is relatively slow, it becomes somewhat challenging for fluidization to occur.
In simple language:
An increase in gas velocity leads to increase in drying rate.
However, the rate should be at optimum, which is neither too fast nor too slow.
It thus implies that air flow rate doesn’t have any significant effect on particles that contain high internal resistance to transfer of moisture.
Clearly, you can see from these operating parameters that they play a critical role in determining the status of the final product.
Now let’s move on and look at the elements in the last category known as product parameters.
8. Batch size
Significantly, variations in batch size of the same material tend to affect the process of drying and granulation.
But it is also important to know that variations from solid state properties originating from batch sizes can modify the requirements of the formulation.
This is in addition to processing and product performance.
Nevertheless, the batch size should be small and augmented based on viability.
9.Moisture in the product
It is also a vital element under the category of product parameter that affects the FBD machine and ultimately influencing the final product.
Ideally, the moisture content of the fluidizing product tends to be one of the essential elements in the process variable of fluid bed drying.
So it happens that in the event that the moisture content in the product is too high, the bed becomes exceptionally wet hence de-fluidizing rapidly.
On the other hand, when the moisture in the product is relatively low, there is virtually no agglomeration that will happen.
The truth, however, is that the probable range of variation in moisture content is considerably constricted.
It thus means that it is a necessity to precisely control all the process parameters which affect the moisture content.
It is also vital to understand that the moisture in the product is at any moment dependent on wetting and evaporation.
Additionally, other product parameters also affect fluid bed dryer as well as the final product in one way or another.
They include; size, shape and the diameter of the particles.
The other one is the moisture content of the specific feed material.
Now it’s my hope you’ve known all these parameters on the basis of category and how they affect the equipment as well as the final product.
So let’s now shift gear and look at the types of fluid bed dryers available in the market.
Chapter 6: Types of Fluidized Bed Dryers
Let me tell you the truth:
In the market, we have several types of fluid bed dryers.
However, making a cost-effective and logical selection of this equipment depends on your familiarity with particular features the various models available.
You’ll find that in several instances, numerous types of this equipment may offer relatively more or less similar performance but at the same cost.
The fluidized bed dryers are categorized into conventional and modified fluidized bed dryers.
But then again, an important aspect worth noting is that not all the modified fluidized bed dryers are substantially better than the conventional ones regarding various elements.
All of them tend to vary when it comes to product quality, energy utilization as well as drug performance among others.
6.1. Conventional fluid bed dryer
So this is the first category of this equipment that we want to expound on.
Generally, the conventional fluid bed dryer refers to those that do not necessarily have modernized features.
In other words, these machines are effective only that they conform somewhat to conventional principles of operation.
In that case, they do not incorporate particular technological advancements that are relatively specific to the task in need.
What this means is that they are more effective when it comes to the general use of the equipment in drying the particles and not specific tasks like the modified FBDs.
Some examples of conventional fluid bed dryers include
i. Batch FBD
ii. Semi-continuous FBD
iv. Continuos FBD
v. Plug FBD among others.
They have different features but tend to operate in a more or less similar manner.
Of course, conventional fluid bed dryers also have some operative features.
One of the significant features is that these types of fluid bed dryer can be multi-functional.
It means that this type of equipment is capable of providing drying function, cooling function, classification and sterilizingtasks among others in a single unit.
You see, this is an critical prospect given that the trend nowadays is to get particular equipment that can offer all these to prevent unnecessary inconveniences.
The other essential aspect of a conventional FBD is that it provides efficiency when it comes to processing without product deprivation.
So that when you use it in processing your grain particles you’re certain that ultimately you will get the high-quality final product.
The final product essentially will not have undergone any form of destruction during the process of drying that would compromise its quality.
This vitally happens because the conventional machines, mostly contain elements that tend to offer gentle fluidizing action.
This type of equipment also ideal because it is efficient, faster and easy to operate.
Also, it supports massive output such that it becomes easy to attain high levels of production.
What’s more is that the performance of conventional fluidized bed dryers is proven to be efficient, easy to clean, durable construction and requires low maintenance.
The only problem like I mentioned is that some are somehow challenging especially when it comes to offering specific tailor-made operations.
6.2. Modified fluid bed dryer
Ordinarily, for quite some time, the conventional fluidized bed dryers have been common in this particular sector.
However, they’ve not been as efficient as you’d expect, especially in the current era of technological advancements.
And to fill this gap, manufacturers have been working extensively to bring on board the various types of machines that match the current needs for better quality and more efficiency.
It is at this point that invention of the modified fluid bed dryer became handy.
What happens is that several types of modified fluid bed dryers are helping in overcoming the numerous challenges that the conventional ones encountered.
Actually, it is a good thing given that most of the conventional fluid bed dryers do not necessarily contain some components available in modified FBDs.
The most important thing to understand concerning this type of fluidized bed dryer is that the incorporate advanced technological elements.
Which in a significant way enhances their efficiency, speciality and production of better quality final products.
We have quite a lot of modified fluid dryers in the market.

Chapter 7: Advantages and Disadvantages of Fluid Bed Dryers
This is arguably one of the best sections of this guide.
You know why?
It is simple; it discusses all the pros and cons of this equipment.
Basically, it helps you to get a more understanding of this machine and whether or not it is worth having in your processing plant.
Any machine must have its two sides. It doesn’t matter which side would supersede the other.
Therefore, without taking much of your time, let’s directly start with the advantages of this machine;
Advantages of Fluid Bed Dryers
Some of the main advantages of fluid bed dryer machines include the following:
· High efficiency in drying material
It is unquestionably one of the obviousbenefits of this equipment.
The efficiency emanates from the fact that this machine utilizes a unique working principle which ensures that the particles dry up individually.
Fluidize dyer process
What happens is that hot air surrounds the entire bed surface which holds the particles which is vital because it helps to increase the efficiency of the drying process.
What’s more is that this high efficiency also arises from the fact that there’s outstanding gas-particle constant.
It is this aspect that results in the high level of heat transfer rates that enhances this effect.
· Rapid and uniform drying
Apparently, this is also another advantage that makes this device worth purchasing.
The thing is, the conventional method of drying particles would not necessarily guarantee you of getting homogenous drying.
The fluid bed dryer, however, assures you of this uniformity when it comes to drying hence making it easy for you to get better quality granules.
This arises from the fact that each particle is covered by hot gas of the same temperature making it possible to achieve it.
Moreover, the working principle of this machine also ensures you of faster drying rates which are vital especially as it helps in meeting your targets accordingly.
· Low capital and maintenance cost
It doesn’t necessarily imply that you’ll have to break your bank account to acquire this equipment.
Of course,prices vary from one fluid bed dryer to another depending on several factors.
But the truth, however – the cost is not to the extreme extent.
So it means that you can still find affordable options to select from when in need but still offer quality.
Furthermore, it is also cheaper to maintain this equipment.
One element that makes this possible is the fact that high-quality stainless steel materials are used to construct this machine.
It thus shows that elements such as dust pollution, corrosion and contamination among others would be a thing of the past.
You won’t strain much in maintaining this machine.
Also, with the many designs available, it becomes easy to modify it to suit your particular specifications that would solve your needs.
· Are available in different sizes and capacities
The truth is that every sector, whether pharmaceutical, research and development or food processing would require unique fluid bed dryer.
In each case, the design has to meet all the specific needs of the intended purpose.
The good thing is that manufacturers also have it in mind hence tend to produce a wide range of fluid bed dryers that meets the needs and standards of different uses.
This is vital because it helps in making sure that you easily access what you’re certain can help you to achieve your needs.
Furthermore, the different sizes and capacities are also an indication that you can purchase what fits within your budget.
So depending on your type of material, you can easily select the type of machine that suits its drying needs.
· Easy to operate and less labor intensive
An essential element regarding most of the fluid bed dryers is that you can transfer them from one location to the other.
Now the advantage that this aspect brings is that it makes it easy to handle the machine as well as reducing the need for much labor during operation.
What’s more is that you can as well find some that have a wheel which makes them highly portable and easy to transport.
It is for that reason that makes them a suitable choice especially for various laboratory needs and on-field research development projects.
· Ideal for products that are sensitive to heat
Ordinarily, some particles or granules damage fundamental components when put under intense heat to dry.
Therefore, the conventional modes of drying become unsuitable for such ingredients.
But on the other hand, the modified fluid bed dryers’ equipment tend to have sensors which are effective.
This then enables the equipment to monitor the necessary parameters and detect any problem during the drying process.
It thus shows that you can be in control of the parameters that determine the quality of the final product even when there’s high rate of heat transfer.
· Final products don’t have hot spots
One of the significant concerns regarding fluid bed dryers is the hot spot on final products.
It is often as a result of direct contact between the products and the drying surface.
But the good thing with the fluid bed dryer is that most of its drying components are suspended within the drying chamber.
Also, you have the option of choosing the appropriate capacity of the fluid dryer to get an excellent mixture of both air and the granules.
What happens typically in various drying applications is that it’s difficult to use high temperatures given that it can destroy the product.
Fluid bed dryer, however, allows you to use high drying temperatures.
What’s more is that the unique working principle of the fluid bed dryer enables the equipment to dry thermolabile products.
Apparently, it is the fundamental reason fluidization tends to be too common in numerous pharmaceutical industries.
These are some of the significant advantages of this equipment.
So let’s also switch gears and look some of its shortcomings;
Disadvantages of Fluid Bed Dryer
Most definitely, you will experience some challenges from time to time whenever you’re using this particular equipment.
It is thus important to highlight a few shortcomings to give you a better understanding of what you would probably experience with this dryer that you won’t necessarilylike.
· Not ideal for drying organic solvents
You see, some particles contain an organic solvent.
So when the need to remove them in the drying process becomes quite cumbersome.
The organic solvents typically dissolve into the material hence making it somewhat difficult to get rid of them from the content using this equipment.
· The danger of fire explosion
It is also necessary to understand that this equipment tends to utilize a high level of hot air or gas.
Therefore, it makes it extremely dangerous to try and fluidize flammable or toxic materials.
Undoubtedly, the dangers of fire explosion or flammability will be high hence putting everyone around in jeopardy of the fire.
· High chances of electrostatic build up
Much movement would generate electrostatic charges.
Of course, this something that often happens when drying organic particles.
And in such cases, going for a modified bed dryer that comes with electrical earthing element becomes of significant use.
· High chances of attrition
Due to extreme temperature and airflow conditions that the materials are subjected to among others, this equipment enhances chances of attrition.
In the fluidized state, all the particles are subjected into a state of turbulence.
This increases the chances of the product reducing its strength or effectiveness ultimately.
What often happens is that in some cases, albeit such parameters can be put under control, it becomes difficult to monitor all of them.
So, in any case, there is a parameter that goes beyond control attrition, and even agglomeration, especially of finer particles, tend to occur.
· It is difficult to dry sticky particles using this machine
Ordinarily, the fluid bed dryer is dependent on fluidization principle.
As we all know, this principle calls for free movement of granules.
It thus suggests that it is quite difficult for sticky particles to move freely making it nearly challenging to use the fluid bed dryer machine.
Hence, it becomes unsuitable for dying sticky or adhesive materials.
· Needs increased gas handling and adjustments
A fluid bed dryer requires enhanced gas handling as a result of massive recirculation of exhausts gas that supports high thermal productivity.
This is actually one of the possible changes that you may need to adjust whenever you’re using this particular machine.
Some of the changes you’re likely to face when operating the fluidized bed dryer include poor fluidization and inconsistency in some product quality.
Also, you’re likely to experience the possibility of high pressure dropping from time to time which as well needs your consideration.
All these are some of the significant changes that you will likely encounter intermittently as you operate this equipment.
And for that reason, they need your immediate attention to prevent cases of inconveniences, poor product quality and inefficiencies.

Actually, the size of the material container and other specifications are what determine the capacity of this equipment.
Nonetheless, the production capacity of this equipment can be as large as 250kg.
It all depends on the particular machine application.
At the same time, you also need to look into the total volume of the container.
In reality, this is just the available space within this container for placing the granules or powder.
Typically, you’ll realize that a fluid bed dryer with a relatively large product container volume tends to have higher production capacity.
But you must understand that this correlation is only applicable assuming all other parameters remain constant.
· The volume of air flow
This is also an essential specification to look into in this equipment.
By now it should be quite evident to you that fluidizatio nutilizes air in converting particles into dynamic fluid-like condition.
The correlation here is that higher rate of air flow results in a faster rate of fluidization.
Interestingly, the aspect of air flow volume goes hand in hand with fluid bed dryer compressor.
You can’t talk about one without mentioning the other.
In most cases, you’ll find these air compressors in different designs and configurations.
However, the particular type of air compressor in your fluid bed dryer will undoubtedly depend on the overall capacity of the equipment.

You need to be careful when evaluating the performance of an electric heater.
For instance, ideal temperature range and rate of power consumption are some of these critical aspects.
A blower in the fluid bed dryer refers to the component which pushes air into the fluidization chamber.
What happens is that when you have a blower which is efficient,you’ll attain rapid fluidization and material processing.
More often, you need to find out the number of revolutions per minute as well as power consumption when analyzing ideal blower.
It is also vital to ensure that the blower provides the correct amount of air per hour.
It plays an essential role in determining the rate of fluidization process.
Thus you must ensure that you look into such specific details if at all you would wish to attain the best out of this air blowing device.
· Electric motor
The other essential thing that you have to know is the precise specifications of the motor that the fluid bed dryer uses.
This is the thing:
For a blower to rotate fully at the appropriate speed that guarantees maximum fluidization, the electric motor has to be powerful.
Mostly, the electric motor is the device that enables the movement of any part within the machine by generating sufficient power.
But you also need to know that when it comes to analyzing electric motor for this equipment, rotation speed and power consumption should be your key focus.
Ordinarily, the power consumption is always in Kw whereas rotation speed is in revolutions per minute.
· Spraying mechanism
It is an essential specification to consider especially when it comes to fluid bed dryers engineered for various material processing procedures.
Nonetheless, the type of spraying mechanism to use will also be dependent on the particular application of the equipment.
So you better be specific when it comes to the spraying mechanism.
Additionally, you can always change the position of the spray nozzle whenever you deem it fit for the nature of your application.
· Dimensions and weight
This is an aspect that you can never take lightly when it comes to selecting the fluid bed dryer equipment.
You see, you’ll be working in a confined space.
So you need to ensure that the particular equipment you’re selecting has the size that can fit into space.
Also, you need to have it mind that the technicians operating the machine will also require adequate space to facilitate movement across the room.
Furthermore, the overall weight of this equipment is also a paramount concern that you should have in mind.
Getting all these information will make it easy for you to ultimately choose the specific machine that suits your requirements.
· Control system
The control system is unquestionably one of the most important features to look into especially in the modified fluid bed dryers.
It is an important element since it plays a significant role in how you’ll operate the machine and controlling its different parameters.
The control system consists of elements such as touch screen panel, PLC and HMI among others.
It is this system that enables you to get and relay commands to the equipment.
