Given its expansive range of applications, sawdust charcoal has grown in popularity over recent years. Traditional methods of charcoal production involve the cutting down of trees, which has had an adverse effect on the environment. However, using sawdust has proven to be a more efficient and greener alternative to making charcoal.
Sawdust is essentially valueless waste. A sawdust charcoal making machine converts this waste product to a useful resource through a process referred to as carbonization. This equipment offers an affordable way of recycling sawdust and increases its value.
The sawdust charcoal-making machine converts sawdust into Biochar using the following key stages.
i). Pre-Treatment
The sawdust (which is the raw material in this case) needs to satisfy certain caveats in you want to produce quality and optimal charcoal. For the sawdust to begin pre-treatment, it will need to contain moisture content not exceeding 20%. To ascertain the moisture content, it will need to go through the dryer for drying first.

ii). High-Temperature Carbonization
After the sawdust has been passed through the dryer, it will be transferred to the carbonization furnace. In the carbonization chamber, the sawdust will be exposed to high temperatures in an oxygen-deficient surrounding. The formation of sawdust charcoal begins at around 300 degrees Celsius. You may also be fortunate enough to obtain combustible gas. The formation of charcoal in an oxygen-deficient surrounding under high temperatures obtains high-quality biochar thanks to the increased calorific content. The charcoal that has been generated comprises more than 80% charcoal. This specific charcoal will burn for an extended duration compared to ordinary charcoal.
iii). Condensation Recovery and Sulfur Emission
This step entails the production of other by-products given off by the machine while making charcoal: vinegar and tar. The smoke emanated in the carbonization furnace consists of wood vinegar and wood tar. To obtain these products and decrease smoke discharge, the sawdust charcoal-making machine comes included with a separating tank and condensation tower. Both products are acquired by the biomass charcoal making machine.
The combustible gas will be conveyed through the deducting spray system that can get rid of Sulphur in the gas. From there, the gas can be redirected or collected and used as a means to get fuel for your carbonization furnace.
iv). Charcoal Cooling and Collection
The charcoal created is usually collected while still too hot, and given how natural cooling will take a considerable amount of valuable time, the sawdust charcoal-making machine comes with a cooling unit that decreases the temperature of charcoal to about 30 degrees Celsius which is manageable.
