There are a lot of people who are curious about how the charcoal that is normally used for barbecues is made. In the barbecue charcoal industry is called mechanism charcoal. This kind of charcoal has the advantages of easy to burn, long burning time, high calorific value, environmental protection and no pollution and other characteristics. The raw materials for making barbecue charcoal are: wood chips, sawdust, rice husk, coconut shell, straw, bagasse and so on. The raw materials are made into barbecue charcoal through the steps of crushing, drying, briquette and carbonisation by the charcoal machine.
Raw material selection: you want to make high quality charcoal. Selection of raw materials is the key. Biomass from all walks of life can be used as raw materials for charcoal making. Common raw materials are: branches, logs, bark, sawdust, wood chips, waste wood, bamboo chips, coconut shells, fruit shells, coffee shells, rice husk, wheat straw and so on.
Feeding: through the combination of feeding device, hopper, vibrating feeder, conveying device. Through the material in continuous and stable feeding. Feeding evenly.
Crushing: If the biomass raw materials are smaller materials, such as: wood chips, rice husk, sawdust and other smaller size materials. It should not be crushed. If it is coconut shell, wood, logs, fruit wood and other larger size materials. Then you need to use wood crusher for crushing and grinding.
Drying: the refined material is sent to the drum dryer or airflow dryer. There will be a furnace at the bottom for providing hot air. The loosened granular material is then suspended in the air by the airflow. The hot air is utilised to make full contact with the material. Rapid dehumidification during the drying process. The moisture in the raw material can be controlled between: 8-12%. In the drying process, the material is under the action of hot air. After the dryer, the material is discharged through the dust collector.
Briquette: After drying, the material is sent to the charcoal briquette machine to be moulded by high temperature and high pressure, and finally formed into charcoal rods. It should be noted that: too high or too low water content in the material will affect the rod making. If the water content is too high, it is easy to cause the charcoal sticks not to be shaped. If the water content is too low, it will be scattered slag and so on. Therefore, the moisture in the raw material should be controlled reasonably.
Carbonisation: The produced charcoal sticks are sent to the horizontal carbonisation furnace. After high temperature carbonisation. Heating to: 400-600℃. Make its charcoal stick fully send carbonisation reaction.
Above is the working principle of charcoal making machine. If you are interested in it. Welcome to contact us! Looking forward to your enquiry.
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.
