Biomass continuous charcoal making machine is a special carbonization equipment for dry distillation and anaerobic carbonization of carbon-containing small particle woody materials such as coconut husk, sawdust, bagasse, coffee grounds, palm shells, peanut shells and sunflower seed shells under high temperature conditions.

The carbonization machine adopts the technology of recovering, purifying and circulating combustible gases such as methane, carbon monoxide, ethane and other combustible gases produced during the carbonization process of biomass, which solves the problem of environmental pollution caused by the thick smoke produced by ordinary carbonization furnaces in carbonization projects. It also solves the problem of heat energy required by the equipment, fully achieves self-sufficiency, improves the continuity and economy of the equipment, makes full use of agricultural and forestry residues, turns waste into treasure. It is suitable for large-scale production, with a high carbonation rate, high carbon production rate, energy saving, environmental protection, high-efficiency advantages.

Working principle

    Biomass continuous drum carbonization machine is a professional equipment for continuous high-temperature heating and carbonization of biomass under anaerobic and oxygen-poor conditions. It consists of a carbonization machine, combustible gas purification device, external heating furnace of carbonization machine, feeding conveyor, cooling carbon discharge machine and power distribution operation control equipment, etc.

    The interior of the carbonization machine is divided into four areas: drying area, heating area, carbonization area, and calcination area. The biomass is transported into the drum of the carbonization machine by the conveyor. First, the material is dried and preheated to 270°C by using the thermal environment in the furnace. Above, enter the high-temperature carbonization zone of the drum for carbonization at 350-650°C, and finally, the biomass charcoal is calcined at high temperature in the calcination zone to meet the carbon quality required by the product and complete the biomass carbonization. The air outlet and discharge box equipped with the drum, the combustible gas produced by carbonization is discharged from the air outlet, and the wood tar, wood acid liquid, water and ash are separated through the combustible gas purification system to obtain pure combustible gas, which is sent into the carbonization machine by wind The external heating furnace fully burns and heats the carbonization machine to achieve reciprocating cycle heating and carbonization and continuous production. 

    The carbonized products are discharged from the discharge box into the cold carbon machine, and cooled by water to below 40°C, and the carbonization is safe. The excess combustible gas from carbonization can be used for raw material drying or sent out as fuel.
