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 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.
