Due to the high moisture content of the coffee grounds, in order to facilitate reprocessing and storage, it needs to be dried first. Coffee grounds can be dried using a coffee grounds dryer. The coffee grounds dryer adopts a drum-type structural design, which has a strong bearing capacity and can quickly dry a large amount of wet coffee grounds with even heating.

The recycling of coffee grounds has received more and more attention. Many investors choose to cooperate with coffee manufacturers to process the coffee grounds left over from coffee production and convert them into biofuels, such as biomass pellet fuel for boilers, or new Charcoal for BBQ.
Due to the high moisture content of the coffee grounds, in order to facilitate reprocessing and storage, it needs to be dried first. Coffee grounds can be dried using a coffee grounds dryer. The coffee grounds dryer adopts a drum-type structural design, which has a strong bearing capacity and can quickly dry a large amount of wet coffee grounds with even heating.
Dingli coffee grounds dryer consists of a heating furnace, a feed port, a drum, a filter drum, a conveyor pipe, a cooling drum, a discharge port, etc. The crushed materials with a moisture content of about 35-45% are sent to the drum by the conveyor to achieve downstream drying. Materials are continuously picked up and scattered under the inner layer of the lifting plate, and advance in a spiral shape. After passing through the inner, middle and outer layers, the material exchanges heat with the hot air, and the material that has reached the drying effect is quickly moved out of the drum under the action of the wind. Wet materials that have not reached the drying effect cannot move quickly due to their own weight. The materials are fully dried within the control stroke, thereby achieving the drying effect. The moisture content of the material is reduced to 12-15%, the drying process is completed, and it is discharged by the screw conveyor. The drum is equipped with a vibration cleaning device to prevent materials from adhering to the drum wall.
