Rotary carbonization furnace is high-automatic carbon-making equipment. Its carbonization raw materials are very diverse and most of them are agricultural and forestry wastes, fruit husks, and industrial scraps. Peanut husk charcoal, rice husk charcoal, bamboo shaving charcoal, coconut husk charcoal, apricot husk charcoal, coffee ground charcoal, etc. They are produced through the carbonization mechanism. The carbon material produced by the continuous carbonization furnace is clean, non-toxic, smokeless, and has good plasticity. In short, the market prospect of the rotary carbonization furnace is broad. So quickly contact us to get product price, category, and shipping information!

Raw Materials for Rotary Carbonization Furnace

The sawdust carbonization furnace can carbonize raw materials such as sawdust, rice husks, peanut husks, plant straws, coconut shell, sunflower husks, apricot husks, distiller’s grains, coffee grounds, etc. The raw material of the biomass carbonization furnace is characterized by small materials. They are powder and particles.

If your raw materials are some large wood chips, branches, shavings, etc., they cannot meet the requirements of the drum charring furnace. Don’t worry, you only need to equip a hammer mill in front of the feed system to get the raw materials that meet the production requirements. In addition, the humidity of wood chips should be below 20%. So you can choose to dry naturally or choose a sawdust dryer to reduce the humidity of the raw material.

Working Principle of Rotary Carbonization Furnace

1. Dehumidification process

This process is mainly to remove the moisture of the raw material itself. With the rapid increase of the temperature in the furnace, the biomass moisture decreases. In fact, this is also the process of drying the raw materials. Because the lower the humidity of the raw material, the higher the carbonization rate of the finished product. So the charcoal quality is also better.

2. Pyrolysis stage

The pyrolysis of materials such as wood chips and coconut husks produces components such as wood tar, wood vinegar, and combustible gases. These products are sequentially separated and purified through our purification tanks. The combustible gas after final purification is returned to the combustion chamber of the continuous carbonization furnace for combustion as fuel.

3. Carbonization stage

The continuous rice husk carbonization furnace only needs to be preheated once (1h). The material carbonization time is about 20-30 minutes. And it is continuous carbonization equipment.

Structure of High-efficiency Coconut Shell Charcoal Making Machine

The roller equipment has three functional areas: preheating area, high-temperature area, and low-temperature area. Carbonization occurs in the high-temperature zone, that is, the main engine part (because it is close to the heat source, it is also called the combustion chamber). There is also an observation hole on the drum to easily see the combustion in the combustion chamber. The drum is driven to rotate by gears and an aperture. But its speed is controlled by the geared motor. Moreover, our motors are all adjustable frequency, which is very convenient.

Infeed and outfeed

Because the material of the rice husk continuous carbonization furnace is lighter. Therefore, the screw feeding and discharging method are cleaner and more efficient. And the discharge pipeline is a double-layer water circulation cooling effect. The finished product temperature is around 35 degrees.


The rice husk charcoal stove has good airtightness, many igniters, and a fast heating speed. It needs to be ignited with liquefied gas. Therefore, the entire production process is environmentally friendly.

Distribution Cabinet

There are several buttons on the power distribution cabinet of the carbonization furnace unit. Customers can not only view air pressure, current, and temperature inside and outside the furnace. And one-button start, manual speed regulation.


Control the speed of the main machine: If the raw material is hard, you can slow down the speed of the main machine to make the carbonization time longer. If the raw material is slightly soft, you can increase the speed to make the carbonization time shorter.

How Is Biomass Carbonized?

When the biomass carbonization furnace reaches a certain temperature, the materials inside the furnace begin to dehumidify. When the temperature reaches about 300 degrees, the material starts to be carbonized. We all know the three conditions that satisfy the combustion of objects: a heat source, combustible material, and oxygen. Because the biomass carbonization furnace is almost a closed space, that is, an oxygen-free environment. Therefore, carbonization of the raw material occurs in the furnace body.

Finished Product of Coconut Charcoal Making Machine

The loose raw materials such as sawdust and rice husks are dried, carbonized, and cooled to become the required charcoal. Therefore, customers can directly sell finished products such as rice husk charcoal, coconut shell charcoal, straw charcoal, and fruit husk charcoal. Customers can also use them for grinding to make charcoal briquette. This creates greater value. Due to the carbon material produced by the rotary carbonization furnace being clean, non-toxic, smokeless, high in heat energy, it has a good market and broad prospects.
