The ambient air that has been filtered through primary and intermediate efficiency is heated by the blower of the drying system into the steam radiator to the set temperature of the process, and enters the flash drying main engine. The drying process of the heat transfer medium is completed in the drying main engine with the filter cake to be dried through the spiral feeder. After the gas-solid mixture is separated and filtered by the cloth bag filter, the material is separated from the gas of the drying system. The exhaust gas is discharged into the atmosphere by the induced draft fan.
