Dingli alfalfa hay dryer working principle:

The crushed alfalfa hay with a moisture content of about 45-75% is sent to the drum by the conveyor to realize downstream drying. Layer, to realize heat exchange between alfalfa hay and hot air, the alfalfa hay that has achieved the drying effect is quickly moved out of the drum under the action of the wind, and the wet alfalfa hay that has not achieved the drying effect cannot move fast due to its own weight, and the alfalfa hay is fully dried within the control stroke , so as to achieve the drying effect, the moisture content of the alfalfa hay is reduced to 14-18% (customer requirements), the drying process is completed, and it is discharged by the screw conveyor. A special removal device is installed inside the drum to prevent uneven drying of alfalfa hay. The gas process is: the alfalfa hay dryer is equipped with an indirect clean hot air stove. The clean air is pressurized by the blower and enters the heat exchanger to be heated. The temperature reaches 150-350 ° C. After being sucked into the dryer by the induced draft fan after the dryer to dry the material, The moisture is evaporated, the temperature is lowered to 35-55°C and discharged out of the dryer, and the dust-laden moisture is purified and discharged to the standard through the dust collector.
