This machine is used for boiled drying of granulate material with size of 0.1-6mm and is applicable for quick drying of wet granulate and powdery material of finished products and intermediate(semi-finished products) in such trades as pharmacy, foodstuff, light industry and chemical etc.

Under the draught of fan, natural air passes through purification cabinet and heater, and form high speed airflow in small hole of material bed board, which makes the material into boiled(fluiddized) status and then makes the moisture (or solvent) in material vaporized (or volatilized) quickly, thus realizing drying purpose.
