Features of fluidized bed dryer

2026 03/02

Fluidized bed dryer, also known as a fluidized bed dryer, consists of an air filter, heater, fluidized bed unit, cyclone separator, bag filter, high-pressure centrifugal fan, and control panel. Due to the varying properties of the materials being dried, the dust collection equipment can be selected based on specific needs. Both cyclone separators and bag filters can be chosen simultaneously, or only one type can be selected. Generally, for heavier materials such as granules and powders, only a cyclone separator is needed, while lighter granular and powdery materials require a bag filter. Pneumatic feeding devices and belt conveyors are also available as options.
 
Overview: Granular solid materials are added to the fluidized bed dryer via a feeder. Filtered clean air, heated, is blown into the bottom of the fluidized bed by a blower, where it contacts the solid material through a distribution plate, forming a fluidized state and achieving gas-solid heat and mass exchange. After drying, the material is discharged through the discharge port, and the exhaust gas is discharged from the top of the fluidized bed. The solid powder is recovered by the cyclone dust collector and bag filter before being discharged into the atmosphere.
Steam, electric, and hot air furnaces can all be used (configured according to user requirements).
 
It is suitable for drying granular materials, such as: raw materials for pharmaceuticals, tablet granules, traditional Chinese medicine powders, plastic resins in chemical raw materials, citric acid, and other powdery and granular materials. It is also used for drying food and beverage powders, grain processing, corn germ, and feed. The particle size of the material can reach up to 6mm, with an optimal range of 0.5–3mm.
