Working principle of alfalfa dryer

ZHENGZHOU, China - April 13, 2023 - PRLog -- How to quickly process or store a large amount of alfalfa during the harvest season and maintain the quality of alfalfa? How to dry alfalfa quickly?

Working principle of alfalfa dryer: The material process is: the moisture is about 45-75%, and the crushed pasture is sent to the drum by the conveyor to realize downstream drying. The three layers realize the heat exchange between pasture and hot air, and the pasture that has achieved the drying effect is quickly moved out of the drum under the action of the wind, and the wet pasture that has not achieved the drying effect cannot move fast due to its own weight, and the pasture is fully dried within the control stroke, thus To achieve the drying effect, the grass moisture 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 pasture. The gas process is: the pasture 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. Moisture, the temperature is lowered to 35-55 ℃ and discharged from the dryer, and the dusty moisture is purified and discharged through the dust collector.

The dried alfalfa has a moist color and a non-dry taste. The low-temperature hot air rapid drying process is adopted, so the nutrient loss during drying is reduced to a lower level. Compared with natural drying, the quality of hay processed by the alfalfa dryer is higher. Zhengzhou Jiutian alfalfa drying machine manufacturer customizes a complete set of alfalfa hay processing equipment, including the entire production line of shredders, drum dryers, balers or balers, etc., realizing the mechanization of alfalfa hay processing hay.
