Coffee factories produce a lot of coffee grounds during the production process. The tumble drying production line equipment produced by Dingli can dry the coffee grounds and granulate them as pellet fuel for secondary use.

Introduction to the technological process of coffee grounds dryer
Raw material → feeder → heat source → dryer → discharge machine → induced draft fan → cyclone discharger → water bath dust removal and deodorization device → exhaust gas evacuation and power distribution cabinet.

Advantages of coffee grounds dryer

1. The drying strength is high. Since the material is highly dispersed in the airflow, the entire surface area of the particles is extremely dry and effective.

2. Short drying time.

3. The air flow dryer has a simple structure, a small footprint, and is easy to build and maintain.

4. Large processing capacity and high thermal efficiency. When drying unbound water, the thermal efficiency can reach 60%.

5. The dryer achieves "zero horizontal thrust", which greatly reduces the wear of the supporting roller, and the cylinder runs smoothly and reliably;

6. The dryer adopts "aligning roller device", so that the cooperation between the roller and the rolling ring is always in linear contact, thus greatly reducing the wear and power loss.
