How to make charcoal from coconut shell?

Coconut shell charcoal is a sustainable and eco-friendly resource that converted from agricultural waste product, which is widely used in barbecues, horticulture, water filtration, and even as a component in activated carbon. Well, how to make charcoal from coconut shell?

Carbonization kiln

The oldest method to make charcoal from coconut shell is by making use of the carbonization kiln. First, you can place the coconut shell in the kiln, and then ight the fire. Usually, you can put asmall dry fuel in to make the fire stronger. A layer of leaves and earth 8 inches thick is going to be placed across the raw material. Finally, you can open the kiln in 2 days or less, and you will get coconut shell charcoal. However, this method has low working efficiency, which cannot produce coconut shell charcoal in large quantities.

Therefore, there is other method to make charcoal from coconut shell is by using coconut shell carbonization machine, which has high working efficiency, eco-friendly and low cost. The following is the working process to make charcoal from coconut shell:

Carbonization machine

1. Preheating and drying

First, the collected coconut shells should be dried to remove the moisture, because the dryness of the material directly affects the energy consumption of the equipment, productivity and the quality of coconut shell charcoal.

2. Carbonization

Then put the dried coconut shells enter the carbonization furnace. Adjust the temperature in the carbonization furnace to 400-550 degrees Celsius, and the coconut shell will begin to burn and carbonize. In addition, as the temperature rises, some flammable gases and wood vinegar will move up with the hot air.

3. Cooling

The high-temperature coconut shell charcoal generated by carbonization needs to be cooling before charcoal can be produced. When discharging charcoal, it is necessary to minimize the air entering the furnace body, and strictly ensure that the charcoal discharging temperature is lowered to below the ignition point of the material to prevent coconut shell charcoal from burning after contact with air.

4. Collection and storage

Finally, you can get coconut shell charcoal, tar, flammable gases and wood vinegar.

Advantages of coconut shell charcoal:

1. Coconut shell charcoal comes from a renewable resource, reduces deforestation;

2. Low ash residue, the ashes left can be used as fertilizer;

3. It burns hotter and longer than traditional charcoal, sustainable burning for 3 hours;

Compared with traditional conversion technologies, carbonization machine has mature process routes, simple processes, easy operation, low equipment requirements, and is economical and practical. It has both good economic benefits and significant social and ecological benefits. If you're interested in our carbonization machine, welcome to contact us.
