Sawdust Dryer

Drying is significant for the good preparation of resources previous to their briquetting. To build superior quality briquettes with high mass, it is very vital to manage the wetness content of raw stuff to 8-12% before loading the them into briquette machine, so sawdust and other kinds of biomass want to be dried first.

Operation principle:

 The entire systems consist of fan blower, motor engine, fuel boiler, steel pipe, cyclone and air lock.

In this structure, wet objects is input into the hopper by screw feeder; Fuel boiler produces large amount of hot air, that hot air is motivated into steel pipes, varied with wet sawdust and moved through twist pipes and ventilation chamber by the power of fan blower. Fast moving hot air sustains and is mixed with raw material sent by twisting 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. The air lock in the outlet stops the hot air to be exhausted to the atmosphere, but release the dried material via cyclone.

Typical Applications:

Ultimate for subtraction of moisture from free of charge smooth materials which is light and tiny like sawdust, rice shell, milled stalks etc.; suitable for small production scale below 700kgs per hour.

It is suitble for drying materials of moisture 30-35%. It takes the advantages of low cost consumption and high efficiency, reducing the moisture to 8-12%. Wet material is input into the hopper.The stoves (boilers) generate hot air which mixes with wet materials and then is sucked into the pipes by the exhaust blower (fan) quickly. And then hot air are flowing and going though the curving pipes and buffer (drying chamber) of dryer, thus wet materials is finished to dry, and the dried materials are discharged from the outlet with air lock.
