Alfalfa is one of the world's famous fine pastures, rich in protein, crude fiber, vitamins and trace elements. Drying alfalfa is a common method for long-term storage or processing of silage. This article introduces the alfalfa drying process in detail.

Working process of alfalfa hay dryer: alfalfa hay dryer generally uses a three-layer rotary drum dryer, which has large output, high efficiency and energy saving, and small footprint. It is especially suitable for drying high-moisture materials such as pasture when used in conjunction with a clean hot blast stove. Dry, can quickly complete the drying of alfalfa moisture from 65-75% to 14-18%. The dry grass retains the nutrients of the forage, with bright color and fragrant smell.

The material flow is: about 45-75% of the moisture content of the forage is sent to the drum by the conveyor to realize downstream drying. layer, to realize the heat exchange between the forage grass and the hot air quality, the forage grass that achieves the drying effect travels quickly and is discharged from the drum under the action of the wind, the wet forage that does not achieve the drying effect cannot travel fast due to its own weight, and the forage grass is fully dried within the control stroke, thus achieving Drying effect, forage 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 the pasture.

The gas flow is: the pasture dryer is equipped with an indirect clean hot blast stove. The clean air is pressurized by the blower and enters the heat exchanger for heating. The temperature reaches 150-350°C. Moisture, the temperature is lowered to 35-55 ℃ and discharged from the dryer, and the dust-containing moisture is purified and discharged by the dust collector.

Zhengzhou Dingli customizes the supply of alfalfa hay dryer equipment, and optimizes drying process technology and equipment selection and configuration services according to the size of alfalfa hay output, application requirements, cost control, on-site conditions, and investment quotas.
