Today, a customer asked: can any wood make charcoal? Theoretically, any wood can make charcoal. But the actual charcoal effect will be greatly affected by the type of wood, moisture content, production method and other factors. Charcoal making machine is an important equipment for producing charcoal.
Raw Material Selection: The raw materials for wood processing charcoal include all kinds of logs (e.g. hardwoods such as eucalyptus, oak, spruce, maple, beech, etc. and softwoods such as pine, spruce, etc.), agricultural and forestry wastes such as tree branches, sawdust, wood shavings, agricultural wastes (e.g. rice husks, coconut shells, straws, corn stalks, etc.), and so on.
Moisture Content: wet wood takes longer to carbonise and dry out the moisture in it, dry wood carbonisation is actually shorter. However, the quality of charcoal is mainly determined by the lignin content of raw materials, wood with high lignin is easier to carbonise, and the finished charcoal burns for a longer period of time and has a higher calorific value of combustion.
Modern Process: firstly, the wood needs to be crushed to granular form. Then it is dried, shaped into rods and finally carbonised in a carbonisation furnace. However, the carbonisation furnace requires low moisture content of raw materials.
Traditional Process: It can take logs or branches and process them through high temperature carbonisation furnace, which is suitable for raw materials with high moisture content.
Benefit Difference: the carbonisation efficiency of different wood is different. Generally, each tonne of finished charcoal requires 3-5 tonnes of raw wood. Hardwood is more efficient than softwood.
Environmental Protection: It is recommended to give preference to agricultural and forestry waste (e.g. pruned branches from fruit gardens, waste from furniture factories, etc.), which can reduce the cost of raw materials and minimise the waste of resources.
Sawdust briquette machine is a kind of screw extrusion type press. Also known as: biomass ball making machine and charcoal machine. It is used to make biomass raw material into fuel-type balls. Sawdust briquette machine can take waste agricultural materi
Charcoal briquette extruder machine is also called coal stick extruder. Adopting the principle of spiral extrusion. It is a coal bar forming equipment that compresses the modulated coal powder into a prefabricated shape with a certain strength.
Bamboo charcoal has high utilisation value. In daily life, bamboo charcoal is mainly used to eliminate and adsorb odours. For example, it can be used to eliminate the odour of a new car or to eliminate the odour of a new house after renovation.
Continuous carbonization furnace can directly carbonise: sawdust, coconut shell, rice husk, bamboo shavings, straw, nut shell, coffee shell, palm shell, peanut shell, and other biomass raw materials. It is a new type of carbonization equipment.
Horizontal Carbonization Furnace Also known as charcoal making machine. It can carbonise all kinds of raw materials. The equipment adopts new high temperature dry distillation pyrolysis carbonization technology.
The vertical lifting carbonization furnace uses advanced airflow carbonization. It can produce all kinds of biomass charcoal. The carbonization furnace has convenient operation, environmental protection and energy saving, high production efficiency, and c
Sawdust dryer refers to putting the powder granular wet sawdust. After a high temperature, hot airflow is conveyed and dispersed. Make the moisture in the material evaporate. Sawdust dryer can dry sawdust, rice husk, wood chips, biomass granules...
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 highly efficient, continuous, and fast solid fluidised drying method. Loose powdery or granular materials are dispersed and suspen
