Working Principle
After heating and purification, air is introduced from the bottom by the induced draft fan and passes through the perforated plate of the material hopper. Inside the working chamber, fluidization is formed under agitation and negative pressure. Moisture evaporates rapidly and is carried away by exhaust air to achieve fast drying of materials.



Materials are fluidized while being stirred at low speed to prevent agglomeration. This advantage is particularly prominent for high-moisture and viscous materials.

Materials to be dried (granules or fine powder) are loaded into the dryer hopper. Air is dedusted by a medium-efficiency filter and heated to the required drying temperature by the heater before entering the main tower. As air passes through the perforated plate at the bottom of the hopper, materials inside the hopper are fluidized and dehydrated. The evaporated moisture flows out with exhaust air, filtered by a bag filter and discharged by the fan. Fine powder lifted by airflow during drying is captured by the filter bags and returned to the fluidized bed via the dust cleaning device.

Technical Parameters

Product Features
● A stirrer is fitted in the hopper to avoid agglomeration of wet materials and air channeling during drying.
● Tilt discharge for quick and convenient unloading; automatic feeding and discharging systems can be custom-designed as required.
● Sealed negative-pressure operation with filtered airflow. Simple operation and easy cleaning.
● Fast drying speed and uniform temperature distribution. The drying cycle per batch is generally 20–30 minutes, subject to material properties.

# Product Applications
Suitable for drying wet granules and powdery materials in pharmaceutical, food, feed, chemical and other industries.
● Granules made by screw extrusion, oscillating granulation and high-speed mixing granulation.
● Large granules, small lumps and viscous lump-granular materials.
● Materials with volume changes during drying such as konjac and polyacrylamide.
