Boiling dryer is also called as fluidized - bed. It consists of air filter, heater, fluidized - bed main machine, feeder, cyclone separator cloth bag duster, high-pressure centrifuge fan and operation table. Because the properties of raw materials exist difference, when equip the dust removing equipment, it should consider the practical need. It can select cyclone separator and cloth bag duster at the same time or one of them. In general speaking, it needs to select cyclone separator only for raw material that is large in specific gravity and cloth bag duster for powder and small granule raw materials that is light in specific gravity. Meanwhile there is air feeding device and belt conveyor for selection.

Separated granule solid raw material is fed into fluidized-bed drier through feeder. Fresh air through filtering and heating is sent to the bottom of fluidized-bed by fan and contacts with solid raw material on distributing plate. In this way the fluidized state is formed and the heat exchange between air and solid is carried out. The dried raw material is discharged from outlet and wasted gas is exhausted from the top of fluidized-bed where catches solid powder through cyclone separator, cloth bag duster.

Steam, electricity or hot air furnace can be used (it can be supplied as request) It is suitable for drying separated granule such as, raw material of pharmaceutical industry, tablet, tablet of drink of Chinese traditional medicines; plastic resin, citric acid, other powder and granule of chemical industry, powder of drink, corn embryo feed of foodstuff industry and so on. The Max diameter of raw material to be dried will be 6mm and the best diameter will be 0.5 ~ 3 mm.

This fluidized bed dryer can achieve automation and continuous drying process. It has a high drying speed and a low temperature and the product quality can be ensured, meeting GMP requirements. The heating resource can be steam, electricity or furnace.
