HOME >Air Flow Pipe Dryer



Introduce to Air Flow Pipe Dryer:
The air flow pipe 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.

Working Principle of  Air Flow Pipe Dryer:
The whole system of air flow pipe dryer consists of a fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock. In this system, wet material is feed into the hopper by screw feeder. Fuel furnace produces large volume of hot air. Those hot air is driven into steel pipes, mixed with wet material/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.
