Drying process and sawdust dryer and wood drying kiln for sale

Sawdust Drying machine prepare suitable moisture raw material for biomass briquette press. For briquetting press, it is only to control the moisture of raw material at a reasonable range that can make good reasult of biomass briquettes. Or the briquettes will be broken because of too loose or too dry.

Sawdust Drying Machine Series: 
1. HGJ Series Single Stove DryerThe Moisture reducing rate of the dryer HGJ series is 8-12%. This dryer is equipped with one hot air boiler, it is suitable for drying raw material with moisture content less than 20-25%.If the moisture content of the raw material is higher than that, it will need several times of drying to achieve the requested moisture content for briquetting.

2. HGJ Series Twin Stove DryerTwin boiler dryer is a newly developed dryer with two hot air boilers, it is suitable for drying raw material with moisture content of 20% -45%, it can reduce moisture from 20%-45% to 8-12% only one passage or one time.

Operation Principle of the sawdust drying machine:
The whole system 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 volumn 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 teh discharge end. Humid air is continuously exhausted, thus the material is dried.
