The biomass continuous drum biochar reactor is a specialized pyrolysis equipment that performs dry distillation and oxygen-free pyrolysis of small-sized biomass materials—such as coconut shells, sawdust, wood chips, rice husks, bamboo, eucalyptus, offee residues, palm shells, peanut shells, sunflower seed shells, and more—under precisely controlled high-temperature conditions to produce high-quality agricultural-grade biochar.
The reactor adopts advanced technology for the recycling, purification, and circulating combustion of combustible gases (such as methane, carbon monoxide) generated during the biomass pyrolysis process. This innovative design not only eliminates the heavy smoke pollution associated with conventional carbonization furnaces but also fully meets the equipment’s own heat energy requirements, achieving complete self-sufficiency. By efficiently converting agricultural and forestry residues into premium biochar, the system turns waste into valuable resources for soil enhancement, long-term carbon sequestration, improved water and nutrient retention, and sustainable agriculture—making a significant contribution to environmental protection and the greening of the planet.
1.The biomass continuous drum biochar reactor is a professional piece of equipment that continuously heats and pyrolyzes biomass under oxygen-free or oxygen-deficient conditions to produce high-quality agricultural-grade biochar. It consists of a biochar reactor, a preheating burner (natural gas, diesel, or LPG), a combustible gas purification and recycling system, an external heating furnace, feeding conveyor, biochar cooler, and a fully automated power distribution and control system.
2.The interior of the biochar reactor is divided into four functional zones: drying zone, heating zone, pyrolysis zone, and controlled calcination zone. Biomass is continuously fed into the reactor drum via a sealed conveyor. First, the material is dried and preheated to above 250°C using the furnace’s internal heat environment. It then enters the high-temperature pyrolysis zone (typically 400–550°C, adjustable) where oxygen-free pyrolysis occurs. Finally, the biochar undergoes a controlled high-temperature finishing stage to achieve the desired agricultural quality—optimizing fixed carbon content, porosity, and surface functional groups—before completing the pyrolysis process.
3.The drum is equipped with an air outlet and a sealed discharge box. The combustible gases (methane, carbon monoxide, ethane, etc.) produced during pyrolysis are discharged through the air outlet, then purified by removing wood tar, wood vinegar, water, and ash. The cleaned combustible syngas is sent to the external heating furnace for full combustion, providing the heat required by the reactor. This closed-loop recycling system achieves complete self-sufficiency in energy, ensures continuous and stable production, and significantly reduces emissions. The finished biochar is discharged from the box into the biochar cooler, where it is rapidly cooled by water to below 40°C for safe handling and storage. Any excess combustible gas can be used for raw material drying or exported as clean fuel, further enhancing the overall energy efficiency and environmental performance of the system.

Customize machine solution according to your actual needs.
Carbonization of biomass materials by charcoal machine, carbon content is greatly improved, and the combustion effect is good. After cooling the carbon powder, it can be equipped with a molding device to process carbon rods, carbon blocks, etc., and can also carry out deep processing of activated carbon.
Carbonization furnace is suitable for carbonization of various forestry and agricultural biomass. Such as sawdust, wood chips, bagasse, coffee grounds, bamboo, coconut shell, cherry shell, date, walnut shell, apricot shell, peanut shell, rice husk, cotton stalk, straw, etc.（Note: Some raw materials need to be crushed.）
1.Strong material adaptability. The reactor can process a wide range of biomass feedstocks with moisture content below 20% and particle size below 30 mm, including wood chips (30–100 mm after pre-crushing), making it highly suitable for the customer’s raw material in this project.
2.Excellent biochar quality and high yield. The produced agricultural-grade biochar features high fixed carbon content, large specific surface area, and rich porosity. It is primarily designed as a premium soil amendment for carbon sequestration, water and nutrient retention, pH buffering, and microbial habitat enhancement. It can also be used as fuel carbon, metallurgical reductant, or raw material for activated carbon when required.
3.Precise control of carbonization depth. The residual volatile matter content of the biochar can be flexibly adjusted within 10–25% according to customer needs. Lower volatile content ensures greater long-term stability in soil, while higher content can be retained for specific agronomic applications, fully meeting European Biochar Certificate (EBC) and International Biochar Initiative (IBI)
