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.
(1)Dryer model HGJ-I, HGJ-II for lower moisture content 30%
In the biomass briquette plant, the moisture reducing rate of the dryer HGJ-I, HGJ-II is 8-12%. This series of dryer is equipped with one hot air boiler, suitable for drying raw material with moisture content less than 20-30% for biomass briquetting. If the moisture content of the raw material for biomass briquetting is higher than that, it will need two or three times to dry to achieve the moisture content requested for biomass briquetting plant
Model Power（KW） Capacity Moisture rate of powdery raw materials
HGJⅠ Small single furnace 4.5 300 kg/h under 30%
HGJⅡ Large single furnace 11 500-600 kg/h under 30%
(2)Twin boiler dryer model HGJ-III, HGJ-Ⅳ for higher moisture content 50%
Twin boiler dryer is a newly developed dryer with two hot air boilers, it is suitable for drying raw material with moisture content of 50%, and it can reduce moisture from 50% to 8-12% only one passage or one time.
