Hollow Paddle Dryer

Our hollow paddle dryer is perfect for the heating, cooling, drying and sterilization of materials for a number of different industrial applications. The machine is heat conduction type drying equipment with a horizontal stirring mechanism that can realize continuous operation to maximize production output.

Introduction

Features:

1. Minimal heat consumption: Due to the indirect heating within the chamber and the heat insulation layer within the exterior wall of the dryer, the heat that is generated to dry the materials is kept within the system. The amount of heat generated to evaporate 1kg of water is significantly less than what is required in an open air scenario.
2. Operating Efficiency: The drying unit’s is highly effective with minimal energy use and the entire device is built with a compact structure compared to similar industrial dryers, saving significant floor space within a facility.
3. Wide application ability: The hollow paddle dryer is suitable for working with heat sensitive materials. The typical media include, steam, oils and hot/cold water. The machine is built for continuous operation in any number of different industries.
4. Low emissions: When the dryer is in operation, the chamber is sealed as to keep any dust or vapors from leaking. Some evaporated mixtures require collecting emissions which is possible with a closed circulation within the system.
5. Low operating cost: The dryer only requires one operator to complete the drying process. The efficient design makes maintenance simple and infrequent.
6. Stable operation: The material is effectively mixed and dried due to the simple design of the blade and heat transferring surfaces. The entire machine maintains a standard temperature, humidity and mixing effect to maximize stability.

1.Working Principle

The heat transfer components of the hollow paddle dryer include the paddle itself, the stirring shaft and the surface of the wall of the drying equipment. The structure of the dryer is compact yet the volume of the drying area is maximized given the space available. The stirring dryer begins operation after the material is fed into the drying chamber and begins to heat and stir the load. The stirring mechanism is specially designed to uniformly heat all of the contents and break apart any clumps and large pieces that may form. The drying time depends on the moisture content of the material being dried as well as the specific properties of the material, so the process can take anywhere from a few minutes to several hours. The feeding speed, the stirring shaft speed and the temperature can all be adjusted to complete the desired drying process. When the operation is finished, the hollow paddle dryer employs a piston driven discharging device to quickly and efficiently empty the drying chamber.

2.Applications

The hollow paddle dryer is an extremely versatile piece of machinery. It is often applied for food, chemical, petrochemical, pharmaceutical and waste management purposes. The heat transfer, cooling and stirring abilities allow the device to perform low temperature calcination for certain ores, drying (solvent recovery), heating (melting) as well as sterilization for a wide range of materials. The stirring paddle uses a special compress-expand stirring function to ensure that materials are uniformly mixed every time.
