We are a professional biochar making machine manufacturer, our biochar production equipment is also called drum type continuous carbonization furnace. It is suitable for large scale continuous biochar production. Our biochar making machine uses pyrolysis technology to perform anoxic dry distillation and carbonization of wood, fruit shells, rice husks, garbage, sludge, oil sludge, animal feces, leather and other materials under high temperature conditions in the furnace, and it is an environmentally friendly continuous carbonization equipment with high output.

Biochar Production Process
Carbon-containing lignin raw materials such as wood, rice husks, peanut shells, plant straw, and bark are first crushed by a hammer mill (the particle size is required to be less than 5mm), then put into a dryer for drying or naturally dried in the sun (the moisture content is required to be less than 20%), and then go through drying, drying, carbonization, cooling and other processes in a drum carbonization furnace to turn the loose raw materials into the required charcoal.
Grain powder→Pulverizer→Conveyor→Tumble dryer→conveyor→Drum type continuous carbonizing furnace
It is necessary to process large pieces or long-fiber raw materials into particles or powders suitable for carbonization. The raw materials can be crop straw, wood chips, rice husks, coconut shells, bamboo chips, etc.

Pulverizer
Function: crush larger particles of raw materials into fine particles to improve the subsequent carbonization efficiency.
Conveyor
Function: used to transport the crushed materials to the next process, such as drying or carbonization.
Tumble Dryer
Function: reduce the moisture content of the material and improve the carbonization efficiency. Suitable for raw materials with high humidity, such as wood chips, sawdust, straw powder, etc.
Conveyor
Function: transport the dried materials to the carbonization furnace to ensure continuous production. Usually high-temperature resistant conveying equipment is used.
Drum Type Continuous Carbonizing Furnace
Function: carbonize organic materials at high temperature in an oxygen-deficient environment to generate biochar. It has the characteristics of continuous feeding and discharging, which improves production efficiency.
The rotary carbonization furnace is equipped with biomass gasification furnace, flue gas purifier, fan, self-distributed gas burner, carbonization furnace and other equipment.

Rotary Contnous Carbonization Furnace Working Process
The continuous carbonization furnace adopts the dry distillation carbonization method, making full use of the combustible gases such as carbon monoxide, methane, hydrogen, etc. produced in the carbonization process. The wood tar and wood acid liquid are separated through the flue gas purification system to obtain pure combustible gas, which is then fully burned through the self-matching air burner to heat the high-temperature carbonization pipeline (the temperature is generally controlled at around 600°C).
Step 1: Initial Heating & Gas Treatment
Material is heated in the gasification furnace, producing flue gas.
A flue gas purification system treats the smoke, converting it into pure combustible gas.
Step 2: Gas Combustion & Temperature Rise
The purified gas flows to the combustion chamber via an induced draft fan.
High-temperature combustion begins once gas ignites, heating the rotary carbonization furnace to required levels.
Step 3: Material Carbonization
Raw material enters the rotary carbonization furnace through a feeder.
Drying and carbonization occur sequentially inside the rotating chamber.
Step 4: Flue Gas Recycling
New flue gas from carbonization is purified again.
This gas returns to the combustion chamber as a self-sustaining heat source.
Step 5: Final Cooling & Output
Carbonized material moves to a cooling discharge machine.
Finished charcoal is cooled continuously and collected for packaging.
