The carbonization process of carbonized wood
The carbonization process of carbonized wood is divided into the following three processes:
Step 1: Heat up and dry at high temperature in the cellar
Heating up, the kiln temperature rapidly rises to 100 ° C.
Then, when the temperature rises to 130 ° C and remains stable, the wood kiln begins to dry, and the moisture content drops almost to zero.
Step 2: Heat treatment
Once the kiln starts drying, the temperature inside the kiln should rise to between 185 ° C and 215 ° C. According to the final use of carbonized wood, this temperature should last for 2-3 hours.
Step 3: Air conditioning and humidity adjustment
The final stage is to use a water spray system for cooling; When the temperature drops to 80-90 ° C, start humidifying again to achieve a usable moisture content of 4-7% in the wood.
