As we know the coconut tree has many benefits, all parts of the coconut tree can be utilized. One of them is a coconut shell which can be used for charcoal. Then, how to process it? Well, in this article we will discuss the coconut charcoal manufacturing process.
The Process Of Making Coconut Charcoal
In general, coconut shell charcoal can be made in two ways, using a drum and drilling a hole in the ground. The raw material for coconut shell is dried first before being burned to speed up combustion and prevent smoke from rising.
Clean the shell of coir, sand, and other debris. Then, cut the shell 2.5 cm x 2.5 cm so that it fills the drum or hole more and cooks evenly. Remove any coir, sand, or other debris from the shell. The shell should then be cut 2.5 cm by 2.5 cm to cook evenly and fill the drum or hole.
In order to produce high-quality charcoal, coconut shell charcoal briquettes must be burned. You can burn it by using a precise mechanism at a temperature that is high enough for the fuel. The ideal temperature for burning coal is around 1000 degrees Celsius. Let it sit and close tightly after it has been burned until the fire goes out on its own. The covered in sand on the firebox.
4 kg of raw coconut shells are required to produce 1 kg of charcoal from coconut shells. This is the ratio 1 : 4. There are 2 ways of coconut charcoal manufacturing process.
Naturally Extinguished
The dead vacuum burning process involves burning palm shells at a temperature of 1000°C for 24 hours, then burying and covering with sand for 24 hours until the flames of the coconut shells naturally extinguish.
To produce perfect coconut shell charcoal, the charcoal is left to naturally extinguish without being soaked in water during this procedure. The produced charcoal contains approximately 7000 Kilocalories per kilogram.
Extinguished with water
This is the process of making charcoal by burning charcoal until it takes less than 1 day. The charcoal will be extinguished by dousing it with water. The process is faster, but with this method, the coconut shell charcoal produced has a high water content, which can reach up to 20%.
After completing coconut charcoal manufacturing process, the next step is the manufacture of export quality coconut shell briquettes. For the manufacture of coconut shell briquettes that need to be considered is the raw material of the coconut shell must be clean from the rest of the burning coconut powder. The finished charcoal briquettes must be sifted so that it can separate the coconut powder impurities.
The Process of Making Coconut Shell Briquettes
Charcoal that has gone through manual combustion or using the pyrolysis process will then be floured using a disk mill machine. Prepare selected coconut charcoal that is ready to be crushed and mashed.
After going through the charcoal crushing process, the next process is sifting in order to produce coconut shell charcoal with a softer and smoother size. Sift using a 50 mesh sieve.
The refined coconut charcoal is mixed with tapioca flour water. The ratio is 5% tapioca flour water compared to 95% charcoal that has been mashed. You can also mix it with the starch glue dose is 2.5% from the coconut shell flour.
After all the ingredients were mixed evenly, then do the printing process using a mold. Finally, dry the briquettes that have been printed using an oven at 650 degrees Celsius for approximately 2 hours. This drying can also use the help of sunlight.
Well, that’s all the information about coconut charcoal manufacturing process. Hopefully this information can be useful for you.
