Fluidized Bed Spray Dryer Grain Fluid Bed Dryer
Product Description
Fluidized bed dryer is also called fluidized bed. The drying chamber is rectangular box type, the botom is uniform air chamber, and aporous air distribution plate is arranged between the air chamber and the drying chamber. Usually, a plurality of vertical baffles arearranged in the drying chamber to divide the fluidized bed into a plurality of small chambers, and each partition plate can adjust thedistance between the bottom and the sieve plate up and down, so that the drving time of the material is more uniform, The powderygranular material is continuously fed into the first chamber of the dryer by the feeder. Since the material is in fluidized state, it can freelymove from the first chamber into the adiacent rear chamber, and the dried product is discharged from the last chamber.
Specification

Characteristics
1.Simple structure, convenient overhaul.
2. Simple steady operation.
3. The air and solid contact evenly with high thermal efficiency4.Low expenses of equipment maintenance,
5.Capable of lower temperature drying for the heat sensitive material6.Integration of drying and cooling bed, small floor space, low investment.
Working Principle
The fluidized bed is divided into the upper and lower bed body, air distributor, the inlet and outlet ports, etc., and the wetmaterial entering the fluidized bed is in contact with the hot air above the air distribution plate, and the material paticlesare suspended in the alr flow to fom a fluidized state. The material and the hot air are heat-exchanged and dried. and theinished product is dischared fomthe discharoe por ofthe fluidized bed. and the dustcontaining gas is puifed by the dust colecino device and then discharaed into theatmosphere by the induced draft fan.
