You can use carbonizing machine to carbonize coconut shells into charcoal directly. So we have different types of carbonization furnaces, almost all of them can be used for making coconut shell charcoal. For the small scale charcoal production, you can choose the hoisting and horizontal carbonization furnace. For the big charcoal factory, you can choose the continuous carbonizing machine.

Coconut shell charcoal keeps the shell shape or break into pieces after carbonizing. このために, before making briquettes, you need to grind them into powder. And charcoal powder is much easier for shaping and can reduce the wearing of the machine. Hammer mill and Raymond mill are the best choices for you.

As coconut charcoal powder has no viscosity, we need to add a binder to help it form into briquettes. With a binder, the charcoal briquettes are more solid and the surface is more smooth. And the most common binder is corn starch and cassava starch. Because they are food grade and have no noxious gas after burning. Usually, the binder ratio is 3-5%.

This step is the most important in coconut shell biochar briquette making. Under high temperature and high pressure, the charcoal powder is briquetting into machines. And there are types of machine for your choice. Such as charcoal rotary tablet press, charcoal extruder machine, チャコールボールプレスマシン そして 水ギセルプレスマシン. You can choose them according to your needs.

To prevent the soil or other impurities adhere to the surface of charcoal briquettes, we suggest you put the briquettes on a tray, plastic cloth, 等. And then it is better to put them on the shelf in case the rain or any unexpected damage. Usually, it takes around 4-7 days to dry the briquettes fully by natural drying. If your budget is not enough, you can choose this way.
