In the biomass briquette plant, this type of dryer is suitable for drying heat sensitive material which is light and
small like sawdust, rice shell, milled stalks etc. Generally wet material can be dried in a few minutes.
Comparing with rotary dryer, it has the advantages of low energy consumption, low cost. In spite of simple
design, it has good effect and high efficiency.

The whole system consists of fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock. In this
system, wet material is put into the hopper by screw feeder and at the same time fuel furnace produces large
volume of hot air, which is driven into steel pipes, mixed with wet sawdust and attracted 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.
