Coconut charcoal briquettes are a type of charcoal made from the coconut shell, which are a abundant resource in many tropical countries, particularly in Southeast Asia, and especially in Indonesia. They are a popular alternative to traditional wood-based charcoal due to their high heat output (calorific value), longer burning time, and lower ash content. Additionally, coconut charcoal is considered a more environmentally friendly option as it is made from a readily renewable resource, abundant wasted material, which produces less greenhouse gas emissions during the production compared to the other traditional charcoal. Coconut charcoal briquettes are commonly used for grilling, barbecue, and other cooking purposes.
High quality of coconut charcoal briquette
The best quality of coconut charcoal briquettes are made from mature, high-density coconuts with shells that have a low moisture content. These characteristics are very important because they will ensure that the charcoal burns hotter and longer, how could they produce the amount of ash. Commonly, coconut varieties with thicker shells, such as the "tall" varieties, tend to produce higher-quality charcoal.
However, the quality of coconut charcoal briquettes can also be influenced by the manufacturing process. High-quality briquettes are usually produced through a process known as carbonization, where the coconut shells are slowly burned in a low-oxygen environment to remove impurities and increase their carbon content. The final product should be a consistent, dense, and uniform charcoal with a low ash content.
The making process
So, in general all charcoal briquette has the same manufacturing process (As we have explained about sawdust charcoal briquette's).
Collection and preparation of coconut shells
As usually the coconut shells are "wasted" material, after being collected, it must be cleaned to remove any dirt or debris. Then, they are dried (usually by sun dried) to reduce their moisture content, which helps to ensure consistent burning and minimize the ash production.
As we have explained before about the carbonization, the dried coconut shells are placed in a kiln or reactor where they are subjected to high heat in a low-oxygen environment. This process will remove impurities and more less moisture from the shells, which leaving behind pure carbon only. The carbonization process typically takes several hours and the temperature is carefully controlled to prevent combustion and ensure that the shells are properly carbonized.
After the carbonization process is complete, the shells are allowed to cool down before they are ground into small pieces and ready for the mixing process.
The ground coconut shell pieces are then mixed with a binding agent, such as starch or rice husk ash, to form a mixture. This mixture is then compressed and shaped into briquettes that we know such as pillow shape, cube shape, using a hydraulic press. The briquettes are then dried in the sun or back in a low-heat kiln to remove any residual moisture.
The final step is packaging the dried and cooled coconut charcoal briquettes in bags, boxing or containers for sale.
It's important to note that the quality of coconut charcoal briquettes can vary greatly depending on the quality of the raw materials, the carbonization process, and all manufacturing methods that are being used. To achieve high-quality briquettes, it should have a consistent density, low ash content, and produce minimal smoke and sparks when burned. They should also be made using sustainable and eco-friendly practices to minimize their impact on the environment.
