Coconut shell charcoal is a natural and environmentally friendly biofuel. It is the best fuel substitute against firewood, kerosene, and other fossil fuels. In the Middle East, such as Saudi Arabia, Lebanon, and Syria, coconut charcoal briquettes are used as Hookah/Shisha charcoal. While in Europe, it is used for barbecue.
Carbonization – Crushing – Mixing – Drying – Briquetting – Packing
Put coconut shells into a carbonization furnace, heat to 1100°F (590°C), and then are carbonized under anhydrous, oxygen-free, high-temperature and high-pressure conditions.
Coconut shell charcoal keeps the shell shape or breaks into pieces after carbonizing. Before making charcoal briquettes, use a hammer crusher to crush them into 3-5 mm powders.
As carbon coconut powder has no viscosity, it is necessary to add a binder and water to the charcoal powders. Then mix them together in amixer.
Add a binder and water to the charcoal powders to mix them together.
(Ⅰ). Binder: Use natural food-grade binders like corn starch and cassava starch. They do not contain any fillers (anthracite, clay, etc.) and is 100% chemical-free. Usually, the binder ratio is 3-5%.
(Ⅱ). Water: Charcoal moisture should be 20-25% after mixing. How to know whether the moisture is ok or not? Grab a handful of mixed charcoal and pinch it by hand. If the charcoal powder doesn’t come loose, the humidity has reached the standard.
(Ⅲ). Mixing: The more fully mixed, the higher the quality of briquettes.
A dryer is equipped to make the water content of coconut charcoal powder less than 10%. The lower the moisture level, the better it burns.
After drying, the carbon coconut powder is sent to a roller-type briquette machine. Under high temperature and high pressure, the powder is briquette machine into balls, and then smoothly rolls down from the machine.
The ball shapes can be pillow, oval, round and square.
Coconut charcoal powder is briquetted into different types of balls.
Pack and sell coconut charcoal briquettes in the sealed plastic bags.
