From biomass materials to charcoal briquettes, there are 3 basic steps: raw material processing, briquetting and charring.
Raw Material ProcessingFrist of all, you should make the biomass raw materials well-prepared for charcoal briquette press. Crusher and dryer machine is needed in this process. Crush the materials to small pieces and dry them to certain water content. If your raw material for charcoal production is sawdust or other powder materials, then crusher machine is unnecessary.
Biomass BriquettingKeep the temperature of briquetting process around 230 degrees. Under this temperature, the final biomass briquettes will be pale black and smooth without cracks. (Standard of briquettes: 3.5cm * 40cm, weight of each briquette: 1.2kg)
Charring / CarbonizationIn the charring or carbonization process, biomass briquettes will be put into a char kiln without oxygen. Charring process plays a very important role in charcoal briquette production and it is one of the main factors that affect the quality of final charcoal briquettes.
The charcoal making process varies between different raw materials. Let’s take sawdust for example.
