How To Make Wood Charcoal

Charcoal is a solid fuel made by burning wood or woody material without air. The burning process removes some components of the wood, leaving behind a porous, hard, black substance. It’s a great option for outdoor cooking because it burns hotter and longer than other fuels.

This can be done in a number of ways:

• Traditional: using pit kilns that will produce low-quality charcoal.
• More industrial: using industrial equipment that will produce high-quality charcoal with a fixed carbon content of over 82%.

Let’s now turn our attention to industrial wood charcoal production.

Raw material for making charcoal

To make charcoal, we can use a variety of raw materials depending on what’s available in our area and what we need.

Some popular options include：

• oak
• Bamboo
• coconut shell
• crop stalks

Raw material processing

Crushing

Sawdust and rice husk can be used directly for briquette production. However, if we’re working with bulky biomass materials like oak and bamboo, it’s important to crush them down to a size of 3-5 mm. Don’t worry though, a crusher can easily process these materials for us!

Drying

To produce charcoal, the material needs to have a moisture content of less than 12%. If the material is wet, it can be effectively dried using a dryer. There are two types of dryers available: an air flow dryer for small capacity and a rotary dryer for large capacity.

Molding

Once the material has dried, we can easily mold it with a briquetting machine.   It’s a crucial piece of equipment for making biochar briquettes. The sawdust briquetting machine, also known as a biomass briquetting machine or charcoal making machine, is a type of screw extruder that produces briquette fuel from biomass material.Shape and size of charcoal can be selected.

Carbonization

The raw material is shaped, it still needs to be carbonized to get the finished charcoal.Let’s dive into the horizontal charcoal furnace, one of the many types of charcoal furnaces.

This carbonization furnace has several advantages:

• Highly efficient in both carbonization and finished product output
• Cost-effective due to the lack of electricity needed for the process
• Easy to move around
