Wood charcoal is an essential fuel and filter material. It is widely used in: barbecue, cooking, heating, water treatment, air purification, and other industrial fields. If you want to produce high quality charcoal, you need to pay attention to controlling the parameters of each link, so as to ensure the charcoal quality and processing efficiency. The waste gas produced during charcoal processing is purified by the flue gas purification system and discharged according to the standard. So what are the five stages of charcoal production?

Raw Material Preparation

The main raw material for charcoal production is wood. For example: pine, birch, fruit wood, fruit shells, coconut shells and so on. Wood needs to be crushed into small pieces first for better carbonisation. When choosing raw materials, you need to pay attention to the type of wood and humidity. The type of wood will directly affect the quality and carbonisation rate of the final product.

Material Drying

The treated wood is initially dried in a wood chip dryer, which is gradually heated to a certain temperature so that the moisture in the wood gradually evaporates.

Wood Carbonisation

As the temperature continues to rise, the wood begins to thermally decompose, releasing organic volatiles. Eventually, the charcoal is carbonised to form the final charcoal.

Charcoal Cooling

After the charcoal has been carbonised at high temperatures, the temperature is gradually lowered to cool the charcoal. This process ensures the quality and hardness of the charcoal.

Grading and Packaging

After cooling, the charcoal needs to be sieved and decomposed again. The unqualified charcoal will be removed. At the same time, the charcoal has to be packed for subsequent storage and packaging.

What Are The Five Stages Of Charcoal Production?

Throughout the charcoal production process, carbonisation temperature and carbonisation time are crucial. Reasonable temperature and time can ensure the quality and yield of charcoal. In addition, advanced and mature charcoal making machine equipment is also crucial. By meticulously controlling the conditions at each stage, it is possible to produce high-quality charcoal products can be produced to meet market and consumer demands.
