Working principle 

rice husk charcoal kiln 

Heating process: input the baskets into the furnace-->heat the furnace to 100-120mins--> stop heating when the temperature up to 300-330 and there are CH4&C2H4 effecting.

Carbonizing processing: normally it takes 8-12hs; during the stage, the material should be pyrolysed, hence need more heating;

Cooling process: after carbonization, taking the inner basket out and then let it cool in natural. It takes usually 80-10hs to cool;

Heating Recycled: after taking the baskets out, another one should be put in, we could recycle the heating resource to carbonizing. 

Furnace structure 

rice husk charcoal kiln 

One main furnace with three inner baskets

Main furnace Includes heating room, furnace body and heat-keeping layer.

Inner basket: resistance thermal steel and sealing cover.

Fume extracion tube: during the carbonizing process, there will be lots of smoke which can be burning; the smoke can return to the furnace through tube air blast carbonization.
