800kg/h Hot Air Sawdust Dryer Machine

Gongyi Yugong Machinery Manufacturing Factory is located in central China, and is a professional manufacturer mainly engaged in designing, manufacturing and exporting biomass pellet making machine such as wood pellet machine, straw pellet machine, sawdust pellet machine, etc.

The hot air stove dryer is mainly used to control the moisture of raw material for biomass pellet press. A reasonable moisture range of raw material can make good result of biomass pelletizing. Without controlling the moisture, the pellets will be broken because of too loose or too dry.

Operation Principle of the hot air stove dryer
The whole system of hot air stove dryer consists of fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock. In this system, wet material is input into hopper by screw feeder. Fuel furnace produces large volume of hot air. Those hot air is driven into steel pipes, mixed with wet sawdust and moved through curving pipes and drying chamber by the power of fan blower. Fast moving hot air sustains and is mixed with raw material sent by spiral feeder in the suspending state through the steel pipe; moisture evaporates as the material traverses along the steel pipe and is rendered dry at the discharge end. Humid air is continuously exhausted, thus the material is dried.
