The spent coffee grounds drying machine can quickly reduce the moisture content of a large amount of waste coffee grounds from 50% to about 15%. It is an efficient machine.

  Working principle: The spent coffee grounds are uniformly and continuously fed into the feed opening of the screw spent coffee grounds drying machine, and the squeezing force is generated on the spent coffee grounds through the change of the screw pitch or shaft diameter to force the water to flow out of the screen of the machine. The feed detection element can be designed on the feed hopper of the spent coffee grounds drying machine, and the speed of the conveying equipment and the rotation speed of the spent coffee grounds drying machine can be automatically controlled by the detection signal.

  The pressing dryness of the screw spent coffee grounds drying machine can be adjusted by hydraulic pressure at the discharge end. The feed port can also be installed with a vibrator to prevent material clogging through intermittent vibration.

  The spent coffee grounds drying machine has more advantages due to its continuous production, large extrusion force, stability and reliability, and simple and easy operation. It can run continuously around the clock without clogging the screen. And the squeezing process is stable, the failure rate is low, and the operation and maintenance costs are low.
