Continuous fluidized bed dryer Horizontal fluid bed dryer

Continuous Horizontal Fluid Bed Dryer  is also called as fluidized-bed. It consists of air filter , heater ,fluidized-bed main machine, feeder , cyclone separator , cloth bag duster (Optional) ,high-pressure centrifuge fan and air pipe ,control chest. 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, 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 (sending air fan) and belt conveyor for selection. 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. The heating way have different kinds to choice such as steam can be used (it can be supplied as client request).

The clean and hot air enters into fluidization bed through distributor of valve plate. The wet material fed from feeder will be
formed a fluidization state by hot air (jumping within the bed like boiling water), so it is called fluidizing dryer(or machine).Because of the large contacting area between hot air and materials, the drying time is short. The air enters from one end of bed, through" boiling" several minutes and then comes out automatically from the other end.
