Sketch：The working principle of GFG series high efficiency boiling dryer is that air is heated and purified, and the induced draft fan is introduced from the lower part through the hole net plate of the hopper.

Sketch：It is composed of air filter, heater, boiling bed host, cyclone separator, bag filter, high pressure centrifugal fan and operating table.

Sketch：The fluidized bed dryer is imported into the machine. Under the action of vibration force, the material is thrown along the horizontal surface fluidized bed, moving forward continuously.

Sketch：The damp raw material enters into helix bed from feed inlet at the top and moves along with the helix bed under the function of excited force and gravity material make jumping motion from up to low until discharged at the bottom layer.
