With the continuous expansion of the demand for biomass fuel energy, coffee grounds have won wide recognition as a new type of granular fuel due to its high calorific value and its unique advantages.

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.

According to market demand, Dingli has launched a coffee grounds dryer for drying wet coffee grounds, including a sawdust dryer consisting of heating furnace, feed inlet, drum, filter drum, conveying pipe,  cooling drum, and discharge port. 

^{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. Moreover, the equipment has large output, high efficiency and energy saving, and a small footprint. Compared with ordinary dryers, it can save energy by 30-50%, which can maximize energy saving and drying costs.}
 

^{1) PLC smart control & high automaticity. The performance of rotary dryer and moisture content of dry materials is automatically controlled in stable states.
2) High heat efficiency. The design of multiple circumferential flights combination and flow rate adjustment devices ensure the control of drying period and temperature distribution. The effect of insulation is as high as 70% and raise the heat efficiency by 20%.
3) Four wheel drive, more steady and stable.
4) Save 50% space compared with traditional dryers and reduce 50% civil investment.
5) Convenient variable frequency control systems. Customer could change the material flow rate and product moisture based on their need.
6) Environmental and safe. Modular configuration of dust collection and purification systems
7) More choice for novel air furnace with high efficiency, convenient manipulation and energy control, which could reduce 30% energy cost and 20% electric cost.}

<sup>Below is Coffee Ground Rotary Drying Machine Drying Process:

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. 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.</sup>

^{We can help optimize the drying process according to the property of different materials, production scale, application requirements, cost control, automation level and site condition.}
 

^{Your device will be packed well in container and suit for long ocean shipping.}
