Nowadays, the usage of charcoal is constantly increasing. Charcoal is becoming more and more common in daily life and industrial production. For example, charcoal can be used in people's favorite barbecues, and its smokeless and odorless properties make it increasingly popular; charcoal can be used as an ideal material for people's heating during winter; charcoal can be used in steel mills for the purpose of slow cooling, and in many other industries. In short, the uses of charcoal are becoming more and more extensive, and market demand is also growing. The term "charcoal machine" has also become internationalized along with the rising popularity of charcoal. Machine-made charcoal produced by charcoal machines is gradually replacing the original primitive earth kilns for charcoal production, greatly reducing people's production costs and multiplying production profits.

>The main parameters of machine-made charcoal produced by machine-made charcoal equipment are: The diameter of the briquettes produced by the briquetting machine is 5 cm, and the length is 50 cm. After carbonization in the carbonization furnace, the length shrinks to about 38 cm. The technical standards for high-quality machine-made charcoal are as follows: Carbon content greater than 85%, calorific value greater than 8000 calories, ash content less than 5%, volatile matter less than 15%, moisture content 4%, smokeless and odorless during combustion, and combustion time should be more than 3 hours. The cross-section of high-quality charcoal has a metallic luster, which is also one of the methods to judge whether it is high-quality machine-made charcoal.

>The machine-made charcoal machine is a collective term for several sets of equipment: The main equipment includes: crusher, dryer, briquetting machine, and carbonization furnace. The raw materials for charcoal machines can be sawdust, rice husks, shells, straw, logs, tree branches, scraps, etc. The humidity of the raw materials should be below 12%, the production site should be larger than 50 square meters, and the height should be greater than 4 meters. The charcoal machine production process is as follows: First, check whether the raw materials are particles less than 1cm. If not, use a crusher to crush the raw materials. Secondly, check whether the humidity of the crushed raw materials is greater than 12%. If so, drying treatment of the raw materials is required. Then, the crushed and dried raw materials are processed at high temperature and high pressure through a briquetting machine to form charcoal rods (semi-finished products). If the charcoal is for burning, this is sufficient. Finally, the semi-finished charcoal rods are placed in a carbonization furnace for carbonization treatment, ultimately forming machine-made charcoal.
