How to Dry out Coffee Grounds
2022-11-14
As a new type of granular fuel, biomass pellets have won wide recognition for their unique advantages; compared with traditional fuels, they not only have economic advantages but also environmental benefits, which fully meet the requirements of sustainable development. The development of biomass energy has good ecological and social benefits. In addition to traditional wood chips, sawdust, wood shavings, straw, etc., coffee grounds have also received more and more attention. Many investors choose to cooperate with coffee manufacturers to process and convert coffee grounds left over from coffee production into biofuels, such as Biomass pellet fuel for boilers, or charcoal for new barbecues.
According to market demand, Dingli has launched a coffee grounds dryer for drying wet coffee grounds, including a sawdust dryer consisting of a heating furnace, a feed inlet, a drum, a filter drum, a conveying pipe, a cooling drum and a discharge outlet. The crushed material with a moisture content of about 35-45% is sent to the drum by the conveyor to achieve downstream drying. The material is continuously picked up and scattered under the inner layer of the lifting board and advances in a spiral manner. After passing through the inner, middle, and outer layers, The heat exchange between the material and the hot air, the material that has achieved the drying effect is quickly moved out of the drum under the action of the wind, and the wet material that has not achieved the drying effect cannot move quickly due to its own weight, and the material is 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. A vibration cleaning device is installed inside the drum to prevent the material from sticking to the drum wall.
Compared with the existing technology, Dingli's new coffee grounds dryer is equipped with a drum to roll the wet coffee grounds, and the hot air is formed by the hot air unit to exchange heat with the rolling wet coffee grounds to dry the wet coffee grounds. The whole process does not need manual operation, and the drying Good effect and good user experience. The equipment has large output, high efficiency and energy saving, and occupies a small area. Compared with ordinary dryers, it can save energy by 30-50%, which can save energy and drying costs to the greatest extent. Welcome to your Inquiry.
