How to make coconut shell charcoal? Actually, it is a thermal decomposition of biomass waste in an oxygen-free atmosphere. The main equipment involved is charcoal making machine, which can process 500 to 3,000 kg of coconut shells per hour. Also, it is more eco-friendly than traditional charcoal kilns. The whole process includes pre-treatment, feeding, coconut shell pyrolysis, discharging, and de-dusting system. Let’s see how to make charcoal from coconut shell step by step.
In order to improve the working efficiency, please break the coconut shells into small pieces (smaller than 20 mm). Also, you’d better dry the coconut shells first. The suggested water content is less than 15%, which will influence the charcoal yield. You can buy a crusher and dryer from Beston if necessary.
The second step is to feed the prepared coconut shells into the charcoal furnace. You can feed manually or use a belt conveyor. If you process sawdust or palm fiber, you may need a scatter as well. Also, you need to choose a non-axis screw feeder. For the different materials, you may need different auxiliary equipment. You can contact Beston for some professional advice.
3. Pyrolysis of Coconut Shell
Beston charcoal making furnace is of double-layer design. It means the outer layer is heated directly, while the inner layer utilizes the residue heat. When the coconut shells are fed in, they will be dried again in the out layer and then be carbonized in the inner layer. When the temperature goes up to 250 ℃, a lot of combustible gas will be generated. Then it will go through cyclone dust remover and condenser to separate tar and wood vinegar out. After that, the combustible gas will be recycled as heating fuel by a draft fan. In general, you can stop using heating fuel in 2 hours. After high-temperature pyrolysis, you can get about 280-330 kg of charcoal from 1,000 kg of coconut shells. In general, the carbonization temperature is from 300 to 600 ℃.
Beston charcoal machine can feed and discharge at the same time. In general, you can get charcoal 15-20 minutes later after feeding. There is a water cooling system to cool down the charcoal to 30-35 ℃ soon. In order to avoid spontaneous combustion of charcoal, it should be stored in the absence of oxygen.
5. De-dusting System
This system aims to remove the harmful things in the exhaust gas. It mainly includes spray tower, fuel condenser, etc. When the fuel gas goes into the spray tower, solid components like SO2 will be mixed in water and then be collected at the bottom of the desulfurization tower. Then the purified gas can be released into the atmosphere safely. And the liquid waste will be recycled after precipitation and alkaline regeneration. Here is the whole coconut shell charcoal production process.
The coconut shell charcoal making process seems difficult. But actually, it is easy to install and operate.
1. It is of continuous design, which can keep working for 5-6 days a week. The whole biochar production process is automatic to lower the working strength. In general, 2-3 workers can run the whole plant safely.
2. The carbonization machine is assembled well before delivery. So it can save your time and money on installation. Below is a test run video of Beston charcoal making machine.
Uses of Coconut Shell Charcoal
Coconut shell charcoal is widely used in different areas. Especially, the coconut shell charcoal quality is far superior to the charcoal from other materials. You can sell coconut shell charcoal at a high price on the market. Below are some of the uses.
- It is popular in food industry, for example, it can be an alternative to regular charcoal in barbecues.
- Coconut shell is a good material for making activated carbon.
- It is a kind of carbon-based fertilizer, which can be used for gardens to improve the soil quality.
- You can also find coconut shell charcoal in water purification, deodorization, and purification of air or water.
Considering the wide applications of coconut shell charcoal, you will find it is profitable to invest in a coconut shell charcoal making machine. Through this article, you may know how to make the best out of waste from coconut shells. If you have any questions, you can contact Beston Machinery for help.
