In the operation process of dryer equipment, fan is an essential part, mainly used in induced draft fan and blower.

The induced draft fan is responsible for quickly discharging a large amount of moisture or drying waste gas generated by the dryer during the drying of materials, so as to accelerate the air flow and improve the drying rate. 

The blower is used with heat source equipment to provide drying medium (sufficient cold air) and ensure the smooth operation of the machine.

It is often used for drying and selecting grain.
