Charcoal briquettes drying
All of the charcoal briquettes are wet after being produced by the charcoal briquette machine. So drying is necessary before they are used as fuel or sold on the market. No doubt there are two ways to dry the charcoal briquettes. One is natural drying in the sun, the other is drying by machine.
To prevent the soil or other impurities adhere to the surface of charcoal briquettes, we suggest you put the briquettes on a tray, plastic cloth, etc. And then it is better to put them on the shelf in case the rain or any unexpected damage. Usually, it takes around 4-7 days to dry the briquettes fully by natural drying.
There are two types of dryers for drying charcoal briquettes: mesh belt dryer and box-type dryer.
Mesh belt dryer
The whole drying process is fully automatic and only 2-3 hours. Charcoal briquettes are fed into the dryer by the conveyor. Inside the dryer, there are 3-4 layers or more mesh belts. Charcoal briquettes move very slowly from one layer to another. Hot airflow from the bottom to the top takes away the moisture.
Box-type charcoal dryer
The box-type charcoal dryer consists of a heating system, exhaust system, insulation house, shelves, and trays. Its drying theory is similar to airflow drying. Put charcoal briquettes on the tray and then place the tray on the shelf. The hot airflow takes away the moisture. You can choose combustion heating or electric heating. Drying time is around 5 hours, mainly affected by the heating temperature and charcoal briquette moisture.
