Coffee grounds are a by-product of coffee production in coffee factories. The composition of coffee grounds is relatively complex. After drying, they can be used as soil additives or granulated to make biomass pellet fuel. Vietnamese customers ordered our coffee grounds drying and granulation production line equipment to process coffee grounds as granular fuel.

Process flow of coffee grounds dryer:

Raw material → feeder → heat source → dryer → discharger → induced draft fan → cyclone unloader → water bath dedusting and deodorizing device → waste gas exhaust and power distribution cabinet.

Features of Jiutian coffee grounds dryer:

1. The self-insulation thermal efficiency of the cylinder is as high as 70% (the thermal efficiency of the traditional single cylinder drying is only 30%).

2. The tail transmission is adopted, and the transmission is more stable and reliable; it completely changes the phenomenon that the supporting wheel often slips and affects production.

3. Compared with the single cylinder dryer, it occupies about 50% less land, about 50% less civil construction investment, and 60% less power consumption.

4. A variety of circumferential lifting materials are combined and distributed to effectively control the drying time and achieve a good drying effect.

5. The desired final moisture index can be easily adjusted according to user requirements.

6. The material flow is controlled by frequency conversion, and the desired final moisture index can be easily adjusted according to user needs.

7. The whole system is equipped with material blocking alarm and anti-riot device.
