Working Principle:

Wet material is inputed into the hopper. The stove(boiler) generates hot air, hot air mixed with wet sawdust and then sucked into the pipes by the exhaust blower(fan) , flowing and go though the curving pipes and buffer(drying chamber) of dryer, thus the wet sawdust is dried, and the dried sawdust is discharged from the outlet with air lock.

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 comsumption, low cost, it's simple designed but high effect as well.

The feeding of fuel for boiler is by manual. The fuel can be wood waste like tree branch, tree trimmings, wood chips, coal or any other waste that can burn (But Gas or Oil is impossible for the boiler now).

Sawdust Dryer Model HGJI
Drawing Of Sawdust Dryer Model HGJII

(1) Dryer model HGJ-I, HGJ-II, HGJ-III for lower moisture content 12-25%

The Moisture reducing rate of the dryer HGJ-I, HGJ-II, HGJ-III 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.
