1.Heat
After sealing work, use wooden wastes or gas to heat furnace. Primarily, 10 minutes big fire to burn, when the temperature reaches
90 degrees centigrade, turn to use slow fire to heat. It takes 80-120minutes for this process to reduce water vapor from your
materials.
2.Pyrolyse
Keep heating, when the temperature reaches 180-235 degrees centigrade for 3-5hours, it will produce gas from this process. Reuse
this gas as fuel to heat. The whole process is about 8 hours. When the temperature reach highest and it reduces, the dry
distillation process will finished.
3. Cooling
Hoist the Inner pot/tank outside, and seal the pipes of cover. Let it cool naturally. Cooling time is longer, the quality of
charcoal is good. When the temperature lowers than 50 degree, you can take charcoal out. Otherwise, the charcoal will burn again
when met oxygen of air.
