The core principle of charcoal making is through high temperature oxygen-poor atmosphere conditions. The organic matter in the wood is decomposed and the carbon element is retained. Modern mechanism charcoal is the mainstream process, more suitable for industrial production.
Raw materials for industrial charcoal come from a wide range of sources, such as wood chips, sawdust, shavings, fruit shells, coconut shells and other agricultural wastes can be utilised. The raw materials need to be crushed to 3-5mm granules. The moisture content of the fibrous material should also be controlled at 8-12%. If it is pine shavings and peanut shells mixed at 7:3 can enhance the combustion value of the finished product. If the charcoal is made of bamboo chips, the hardness will be higher.
The dryer adopts three-layer drum structure. The temperature can be gradually increased from 80℃ to 120℃. So that the water content in the raw material will be to 8%. The charcoal briquette machine softens the lignin through 320℃ high temperature and extrudes hexagonal pay sticks under high pressure of 1.8MPa. The wood sticks produced have a mirror-like luster on the cross section and sink when they are in water.
The carbonation furnace is divided into three zones: preheating stage (200-300°C), pyrolysis stage (350-550°C), and calcination section (600-800°C). A micro-negative atmosphere environment can be maintained by adjusting the air inlet and flue gate. The carbonisation furnace can be equipped with PLC intelligent control system. Precise temperature control. Greatly shorten the carbonisation time.
Environmental protection policy requirements in different regions. The whole set of charcoal making machine can be equipped with flue gas purification system. If entrepreneurs give priority to agricultural waste. Both can reduce the cost of raw materials . It can also avoid the native forest. In the process of producing charcoal, the oxygen content and temperature gradient in the carbonisation stage are precisely controlled . It is the core secret of producing high quality charcoal.
Sawdust briquette machine utilises raw materials such as sawdust, crops, straw, bagasse and so on. After crushing, the raw materials are processed into hollow bar body in high temperature and high pressure area.
Charcoal Briquette Extruder Machine is also called coal stick extruder. Adopting the principle of spiral extrusion. It is a coal bar moulding equipment that compresses the modulated coal powder into a prefabricated shape with a certain strength.
Bamboo chips are the main raw material. After drying in the drying machine, the material is dry and wet properly. After cooling, the material passes through the bamboo charcoal machine. After high temperature, high pressure and plasticisation.
Continuous carbonisation furnace is a new type of charcoal production equipment. He can be used to produce large-scale rice husk charcoal, sawdust charcoal, coconut shell charcoal, nut shells and so on. Through the oxygen-free carbonisation and dry distil
Horizontal Carbonisation Furnace Also known as charcoal making machine. It can carbonise all kinds of raw materials. The equipment adopts new high temperature dry distillation pyrolysis carbonisation technology.
Vertical lifting carbonisation furnace is using advanced airflow carbonisation. It can produce all kinds of biomass charcoal. The carbonisation furnace has convenient operation, environmental protection and energy saving, high production efficiency...
Sawdust dryer refers to put the powder granular wet sawdust. After high temperature hot airflow conveying and dispersing. So that the moisture in the material is evaporated.
The air flow dryer is widely used for drying powder-like material. The humidity can be controlled at 10-16%. It is a kind of high efficient, continuous and fast solid fluidised drying method.
