Sawdust charcoal making machine can convert waste sawdust into an economically valuable charcoal under oxygen-free and high temperature conditions. During the sawdust carbonization process, it is heated to a temperature of 300 to 800 degrees Celsius. This causes the organic matter to decompose into gases, liquids and solids. The gases and liquids are usually collected as fuel, while the solid residue is biochar.
Sawdust charcoal can be used as a soil conditioner as it helps improve soil quality, fertility and water retention. It can also be used as an energy source or carbon sink as it can be stored for a long time and helps reduce greenhouse gas emissions.
Sawdust Charcoal Making Machine Working Process
Preheating and drying
Turn on the burner to preheat the sawdust charcoal machine reactor for 1-2 hours. The fuel can be diesel, liquefied petroleum gas, natural gas, etc. When the temperature reaches about 150 degrees, you can start loading.
The sawdust will be loaded into the dryer for dehumidification. The heating source is the flue gas in the combustion chamber of the carbonization furnace.
Pyrolysis Carbonization
After the sawdust passes through the dryer, it enters the carbonization reactor. The material first enters the inner barrel for further drying, and then falls into the outer barrel to complete the pyrolysis carbonization process. After the water-cooled circulation system, the temperature of the sawdust charcoal will decrease. The generated sawdust charcoal is automatically discharged by the screw conveyor.
Collection of Syngas and Tar
The syngas and tar enters the dust collector and condenser for impurity removal and cooling. The syngas that cannot be condensed is partially recycled back to the furnace for heating, and the excess syngas enters the combustion chamber. Tar and wood vinegar are collected and stored in a storage tank.
Flue Gas Purification
The flue gas in the heating process enters the dryer and impurity remover for drying and purification. Then the flue gas enters the dust removal scrubber, passes through ceramic ring adsorption and water spray. Finally, it is cleaned by ultraviolet light and oxygen and activated carbon adsorption to remove unpleasant odors and digest CH4. This is particularly important for the generation of carbon credits.
Dust Removal
The flue gas from the combustion of syngas also passes through the flue gas condenser and then transferred to the dust removal process for cleaning.

Charcoal making machines recycle waste sawdust, providing an effective solution to the waste problem in the wood processing industry. They use waste sawdust as raw material and, through a series of processes, transform it into economically valuable charcoal, achieving resource recycling. This not only reduces environmental pollution from waste but also creates additional economic benefits for businesses.
Sawdust carbonization plant also demonstrates high energy efficiency. They fully utilize the heat generated during the sawdust forming and carbonization processes. Through a comprehensive heat exchange system, the charcoal making machine recycles this heat for use in drying and preheating the raw materials, significantly reducing energy consumption.
Sawdust charcoal making machines also produce low pollutant emissions during the production process. They utilize advanced exhaust gas treatment systems and environmentally friendly processes, effectively reducing the generation of waste gas, wastewater, and waste residue.
