Curious about how to make charcoal from coconut shell in an efficient and sustainable way? This guide offers a detailed step-by-step process to transform coconut shells into high-quality charcoal. The whole process is from sourcing the best raw materials to selecting the right equipment and mastering the production techniques. we’ll explore everything you need to know to create valuable coconut shell charcoal for industrial or personal use. Whether you’re a small producer or planning large-scale production, this guide will help you optimize the process of how to make coconut charcoal.
Step 1: Obtaining Coconut Shells
As main raw material for making charcoal from coconut shell, coconut shell’s acquisition method and quality directly affect the economic and sustainable production. The following will tell you how to obtain coconut shell raw materials efficiently.
Where to Obtain Coconut Shells?
Coconut Plantation
Coconut plantations are widely distributed in tropical and subtropical regions. In order to reduce transportation costs, some plantations peel coconut shells and only transport coconut meat or coconut water to the processing plant. The coconut shells are piled together. Since the yield of coconuts is stable over the year, the plantation can provide stable supply of coconut shells.
Coconut Processing Plant
In the processing of products such as coconut oil, coconut milk, and coconut juice, the processing plants will peel the coconut shells. In coconut processing plants, coconut shells are regarded as low-value by-products. These coconut shells are usually piled together and take up a lot of space. Therefore, coconut shells for processing plants are an economical source of raw materials.
How to Choose High-quality Coconut Shells?
Shell Hardness:
Producers should choose coconut shells with high hardness, tight texture and moderate thickness. This can improve the durability of coconut shell charcoal.
Moisture Content:
Choose coconut shells with a moisture content of no more than 15%. High moisture content will increase drying costs and reduce biomass pyrolysis efficiency.
Impurity Content:
Coconut shells should be free of impurities such as mud, fiber and rotten components. This is to reduce generation of ash during charcoal made from coconut shell.
Step 2: Choosing Suitable Processing Method
Modern Machine
The modern charcoal machine can achieve an efficient and automated carbonization process with the following characteristics:
- Continuous Production: The machine adopts a continuous feeding, carbonization and discharging working mode without stopping.
- Highly Automated: The machine can ensure the consistency of coconut shell charcoal products through precise parameter control.
- High Energy Efficiency: The machine can recover the combustible gas released during the carbonization process for its own heating.
Traditional Kiln
The traditional charcoal kiln is an earlier carbonization equipment, usually operated in fixed or batch mode. It has the following characteristics:
- Low Cost: It is usually built of refractory materials and has a low initial investment cost. In addition, the kiln occupies a small space.
- Flexible Structure: The kiln adopts a simple structure, which is easy to build and move. It is suitable for on-site processing in multiple sites.
- Periodic Operation: The charging, carbonization, cooling and charcoal collection of the traditional kiln cannot be carried out at the same time.
Selection Suggestion
- Due to the operation mode and output restrictions, traditional kiln is more suitable for small producers or enterprises that have just entered the industry. This equipment is usually used to meet the small batch needs of the local market.
- Due to its high efficiency and high capacity, modern machine is more suitable for large-scale production lines. The machine meets industrial-level needs such as bulk biochar production or industrial fuel.
Step 3: Coconut Shell Charcoal Processing
The production process of coconut shell charcoal usually includes four main links: raw material pretreatment, pyrolysis, charcoal collection and molding. The details and video below will show you how is coconut charcoal made. You can follow our YouTube channel for more charcoal production videos.
Drying&Crushing: How to Coconut Pretreat Charcoal
Before making coconut shell charcoal, coconut shells need to undergo certain pretreatment to ensure the smooth progress of charcoal production.
- Crushing: The original coconut shell has high hardness and large size. Crushing is indispensable. The purpose of crushing is to increase the surface area of the coconut shell and promote the uniformity of the pyrolysis reaction.
- Drying: Coconut shells have a high moisture content. Drying can remove moisture, reduce energy consumption during carbonization, and improve carbonization efficiency.
01
Pyrolysis: How is Coconut Charcoal Made
This is the key to how to make coconut shell charcoal. Put the pretreated coconut shells into the furnace for heating. Coconut shells are thermally decomposed in a high temperature and micro-oxygen environment to produce charcoal and combustible gases.
- Charcoal Formation: The internal moisture and organic volatiles in the coconut shell are precipitated under the influence of high temperature. The remaining carbon residue is coconut shell charcoal.
- Gas Recovery: In the coconut shell charcoal machine, combustible gas from pyrolysis process serves as the main furnace fuel.
02
Cooling&Collection: How to Get Finished Charcoal
After undergoing pyrolysis, cools down collect the coconut shell charcoal.
- Cooling: Reduce the temperature of the charcoal by natural cooling or using a water cooling device to prevent spontaneous combustion of the charcoal.
- Collection: Take the charcoal out of the carbonization furnace, perform preliminary screening and cleaning, and store it in a special container.
03
Molding: How to Make Coconut Charcoal Briquettes
The molding process mainly presses the charcoal powder into briquettes for transportation and more coconut charcoal uses.
- Briquettes Molding: For applications that require larger charcoal briquettes (such as hookahs and barbecues), charcoal briquetting machine can press them into blocks.
