Biochar Making Machine

Investing in a biochar making machine is a wise choice which can bring you benefits and help you dispose of the biomass waste. This machine is also called as biochar production equipment and Beston has high-quality and low-energy-consumption machines like this for sale.

Biomass is an industry term for getting energy (biochar or biofuel) by burning wood and all other organic matters. There is a large variety of organic waste, therefore, biomass turns to be very important and useful in the industry of “waste to energy”. Various methods of biochar production from biomass have sprung up recent years, and GreenBeston’s biochar making machines just come into season at the right moment.

The biochar production technology we adopt is mainly carbonization and pyrolysis. During the process, the biomass is carbonized into bio-charcoal under a high-temperature and oxygen-absence environment. Except for biochar, there are also byproducts like wood vinegar and tar. Owing to the differences of the raw materials, the biochar will be different. Mostly, our biochar production units can process wood, rice husk, coconut shells, sawdust, straw, bamboo, palm kernel shells and sewage sludge, etc. But theoretically, it can process all the organic wastes.

Biochar Production Process

1.Drying. The constant weight feeder transits biomass waste (usually in small pieces) to the drying host by belt conveyor. Biomass will go through series of processing like drying and flash steaming and then fall freely down to the carbonization host.

2.Carbonizing. Biomass will go through carbonization and pyrolysis in the host of carbonization. In the carbonization. In a high-temperature environment, it will turn to carbide. After the smoke is discharged and the sulfur is removed, you will get the final product: biochar.

3.The combustible gas generated during the process of biochar production will go to the condenser and then be separated to wood vinegar and tar, which can be used as fuel for the biochar carbonization furnace.

Application of End Products: Biochar, Wood Vinegar and Tar


  • Used as fuel in BBQ, steel factories, ceramics and so on.
  • Used as fertilizer to attach heavy metal in soil and improve the quality of the field.
  • Reprocessed into activated carbon and used in much wider fields.
  • Used to make construction bricks with clay.

Wood Vinegar: fuel; used in agriculture because of the characteristics of antibiosis and insect-resist

Tar: fuel; raw materials to make plastic, synthetic fiber, dye, rubber, refractory materials, etc.

Why You Should Choose GreenBeston

We Are Unique

  • Unique Heating Method: One Fire Two Steps. We are the only manufacturer who adopts this unique heating structure. It means we use only one fire to supply heat for both drying and carbonization hosts. Residual hot smoke generated during the process of carbonization is collected and used to provide heat for drying. So, it largely improves the heat utilization and reduces the cost of fuel for the customer.
  • Unique Structure. The structure of this machine adopts double-layer design, the upper one for drying and the lower one for carbonizing. This design facilitates the One Fire Two Steps heating method and makes sure there is no heat waste.

We Are Green

  • We have particular de-dusting, desulfurization, cooling and filtering systems to filter the combustible gas and residual gas generated during carbonization.
  • The feeding and discharging are sealed to make sure no ashes or dirt posing to the surroundings.
  • We make sure the smoke discharging into the environment meets the EU environmental protection emission standard.

We Are Safe

  • Central control can be designed according to the customer’s request, which can separate the operator and machine.
  • Configured with pressure gauge, pressure relief valves and electronic ignition device to make sure the safety of combustion.
  • Special casing (protective shell) prevents the body contacting the high temperature directly.
  • Power supply section has a standardized control system to ensure safety.

We Are Considerate

  • As a professional manufacturer of carbonization machine, Beston is capable to provide all-around considerate services.
  • We have specialized sales personnel and professional engineers who can help in installation and maintenance.

Tips for You While Using the Biochar Making Machine

1. The temperature of the biochar-making reactor is between 400℃ and 600℃. Higher temperature brings the higher efficiency of carbonizing. As a result,  you should pay much attention to the temperature.

2. Water content of the biomass. To keep a high efficiency of drying, you should make sure the water content of the raw materials within 20%.

3. Size of the raw materials shall not exceed 20 mm in diameter.

4. The heat source can be coal, natural gas, etc.

Whether you plant to do meaningful things for waste recycling or invest in commercial biochar production, you can rely on GreenBeston biochar making machine. This high-output and energy-saving machine can help you to reach to the both goals.
