Coconut shell consists of 30% coconut fiber and 70% pith. Besides that, it contains 0.6% ash ad 36.5% lignin that are helpful to turn it easily into charcoal. As we know, coconut shell charcoal belongs to a natural & environmentally-friendly biofuel. In addition, it can be the best fuel alternative of kerosene, firewood, or other fossil fuels. Understanding coconut shell charcoal briquettes making process can bring you great wealth.
Coconut Shell Charcoal Briquettes Making Process Step by Step
The making process of coconut shell charcoal includes a few steps. Let’s pay attention to every step below:
- Carbonizing
Firstly, put the shells of coconut into a furnace of carbonation. After that, heat it to 590°C. Then, carbonize them high-pressure, high-temperature, oxygen-free, and anhydrous conditions. You have to do it on your own because we do not provide such machine. Certainly, you can select a low-cost method of carbonation: burning the husk of coconut in a big pit. However, this process takes 2 hours or even longer.
- Crushing
Before you make charcoal briquettes, you should crush the coconut shells into 3-5 mm powders. To crush them, you can simply use a hammer. Coconut charcoal powder is easier to shape. It can even reduce the machine wearing. Of course, You can more easily press the smaller particle into charcoal briquettes.
- Mixing
Carbon coconut powder doesn’t have viscosity. So, you should add a binder & water to the charcoal powers. After that, use a mixer to mix them together.
- Binder: Make sure to use natural food-grade binders such as cassava starch and corn starch as the contain no fillers and are chemical-free. Commonly, the binder ration is about 3-5%.
- Water: After mixing, charcoal moisture must be 20-25%. To know if the moisture is good, just grab mixed charcoal & pinch it. If it does not loose, it has the standard humidity.
- Mixing: The more fully mixed will result the higher quality of charcoal briquettes.
- Drying
Drying is the next step of coconut shell charcoal briquettes making process. A dryer has a feature to make the coconut charcoal power’s water content less than 10%. You need to know that the lower level of the moisture, the better it will burn.
- Briquetting
Lastly, send the carbon coconut power to a briquette machine of roller type. Then, the powder will briquette into balls under high temperatures. And they will roll down smoothly from the machine. The shapes of the balls can be square, round, oval, or pillow.
Coconut Charcoal Are the Best Alternative to Traditional Charcoal
Coconut shell charcoal offers some benefits. First, it is pure natural biomass charcoal without chemicals. Besides that, it is easy to ignite. Then, it offers predictable, even, and consistent burn time. In addition, its burn time is longer. Moreover, it can heat up quicker than other charcoals. Other benefits include clean burning, lower residual ash, and needs fewer charcoal briquettes for barbecue.
Well, that’s the coconut shell charcoal briquettes making process. Indonesia is the largest producer of coconut. So, you can find coconut shell charcoal briquettes in Indonesia affordably.
