Applications
It is widely used for medicines, chemical raw material, foodstuff, grain processing, feed and so on. For example, crude drug, tablet granule, Chinese medicine infusion, foodstuff of health protection, drinking infusion, feed, resin, citric acid and other powders. The suitable diameter of raw material will be 0.1-6mm. The best diameter of raw material will be 0.5-3mm.

Clean and hot air enters into fluid bed through distributor of valve plate. The wet raw material fed from feeder forms the boiling state by hot air. Because of the wide contact between hot air and raw materials, drying time is short. The air enters from front of bed, boiling in bed for several minutes, and discharged from other side of bed. The machine works in negative pressure.
