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.
