The airflow charcoal making machine(carbonization furnace) is made of high temperature material by using high-tech environmental purification technology,which is durable without oxidation or deformation. The airflow carbonization furnance have the advantages of good insulation, simple operation, safe and reliable performance, and the dual chimneys can get materials carbonized fully with qualified rate more than 95%, saving time and labor with a person being able to operate several carbonization furnaces.
800kg per batch
1. Reasonable structure, low energy consumption, superheated steam cooling system,
fast cooling speed, good quality charcoal, short production cycle. 2. A horizontal condenser can be used for this carbonization furnace to recover wood tar. 3. This carbonization furnace can deal with log charcoal, machine-made charcoal with
high yield and good quality.

After extruded from the rod machine, the carbonization of rod materials can be 3 steps: low temperature
damp exhaust--high temperature calcination--cooling. Before carbonization, the rod has water content
about 8%, which would be a big problem of carbonization/charring since the moisture will seriously affect
the charring quality. So the moisture removal time must be guaranteed, which needs 10-15 hours for kiln
and 2-3.5 hours for mechanisms kiln. Long heating time can avoid rod cracking caused by moisture, and
gurantee charring quality.
Raw materials of charcoal making kiln
1) Tree branches whose diameter is more than 30mm.
2) Some nut shells, such coconut shell, walnut shell, etc.
3) Biomass briquettes made from sawdust, small agriculture wastes
