How is Coconut Shell Charcoal Made

Learning how coconut shell charcoal is made is a great way to understand how biomass carbonization equipment works.

Pretreatment

Before entering the carbonization system, coconut shells are prepared to meet feeding requirements:

Crushing

Shredded into 10–20mm pieces for even heating.

Drying

Moisture content is reduced to below 15% using a rotary dryer, also minimizing dust and improving fluidity.

Pyrolysis

Prepared coconut shells are fed into the carbonization furnace via a screw conveyor. Under temperatures of 400–600°C, the process converts shells into high-quality charcoal.

Cooling and Discharge

The coconut shell charcoal is cooled rapidly to prevent re-ignition.

Waste Gas Treatment and Emission Control

Flue gas is recycled to preheat combustion air and assist in the drying of raw materials. By-products like tar is collected for industrial use.
