The carbonisation process is the most important part of the charcoal production process. Carbonisation is usually carried out using a continuous carbonisation furnace. The heating rate of carbonisation refers to the range of temperatures and the rate of heating during the carbonisation process. Carbonisation is the process of converting organic material to carbon through high temperature treatment. The specific heating temperatures and rates vary somewhat depending on the carbonisation method.
Low Temperature Carbonisation: The temperature normally used is around 300°C. The carbonisation process does not require drying. No drying is required before carbonising. Carbonisation is carried out at a pressure of 6-8 MPa. The heating rate of this carbonisation method is moderate. Suitable for a specific energy demand. It has the advantages of low energy consumption and low operation cost.
Medium-temperature carbonisation: Temperature range: 400-500℃. The carbonisation process does not require pressurisation. The products are diversified and can be widely used in various industrial fields.
High temperature carbonisation: temperature range: 600-900℃. High temperature carbonisation is suitable for large-scale industrial production. However, the running cost is high and the calorific value of the final product is low.
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.
