The coffee bean roasting machine is a drum dryer, mainly used to dry high humidity materials through heating and airflow to achieve a predetermined drying level.

The drum dryer is mainly composed of drum, burner, air inlet, air outlet, transmission device and other parts. During operation, materials enter the drum through the air inlet, while the hot air generated by the burner enters the drum through the air inlet and transfers heat through contact with the materials, causing the moisture in the materials to evaporate and be carried away. As the drum rotates, the material gradually moves from the inlet to the outlet, completing the drying process. Finally, the flue gas treated by the dust collector is discharged into the atmosphere.

Characteristics of drum coffee bean roasting and drying machine

1. High drying efficiency: The drum dryer adopts intermittent drying, which has high drying efficiency and can significantly reduce the moisture content of materials.
2. Easy to operate: The drum dryer is easy to operate and only requires basic operation and debugging before being put into use.
3. Energy saving and environmental protection: The drum dryer adopts circulating air treatment technology to fully utilize heat energy and achieve energy-saving effects. Meanwhile, the emitted flue gas undergoes dust removal treatment, resulting in minimal environmental pollution.
4. Wide applicability: The drum dryer can process materials of various shapes and sizes, suitable for drying materials of different shapes such as powders, particles, and flakes.
5. Easy to operate: The operation and maintenance of the drum dryer are relatively simple. Generally, it only requires adding materials into the equipment and adjusting the drying parameters to achieve drying.
