How to make charcoal from coconut shells
1. Carbonize coconut shells into charcoal
Coconut shells can be carbonized into charcoal directly through a carbonization furnace. We have different types of carbonization furnaces, and almost all of them can be used to make coconut shell charcoal. For small-scale charcoal production, you can choose a hoisting carbonization furnace. For large charcoal factories, you can choose a drum carbonization furnace.
2. Coconut shell charcoal crushing Coconut shells remain in shell shape or break into pieces after carbonization. Before making charcoal, you need to grind them into powder. Charcoal powder is easier to shape and can reduce the wear of the machine.
3. Mix charcoal powder with water and binder Because charcoal powder has no viscosity, we need to add binders to help it form charcoal blocks. With binders, charcoal will be stronger and the surface will be smoother. The most common binders are corn starch and cassava starch. They are food grade and have no harmful gases after burning. Usually, the binder ratio is 3-5%. Regarding charcoal moisture, it should be 20-25% after mixing. In production, there is a good way to know whether the moisture is normal. Take a handful of mixed charcoal and pinch it with your hands. If the charcoal powder is not loose, the humidity is OK.
4. Coconut shell charcoal briquetting Coconut shell charcoal can be used for hookah, barbecue, cooking, heating boilers, etc. The following are our 5 types of charcoal briquetting machines for making different charcoal shapes and sizes to meet the various uses of your charcoal.
5. Drying of charcoal briquettes All charcoals are wet after they are produced by charcoal briquetting machines. Therefore, drying is necessary before they are used as fuel or sold in the market. There are two ways to dry charcoal briquettes. One is natural drying under the sun, and the other is machine drying.
