You had biomass materials like coconut husks, rice husks, sawdust, etc. You also had a roller briquette machine that performs well. But the charcoal briquettes you got are not of good quality. How come?
You didn't dry the raw material.
The raw materials are available in higher moisture contents than what required for briquetting. The moisture content of raw material is required to be between[b] 6% and 12%[/b].
Drying can be done in open air (sun). But this is too time consuming. Therefore, you need a rotary dryer. Rotary dryer or drum dryer is a type of dryer that is most widely used in the pellet and briquette industry. That is because the rotary dryer has a simple construction, easy to operate and also maintenance.
