[0002] Grass processing is the production process of changing fresh grass into hay, silage or semi-dry silage, and the drying process of grass in grass processing is very important in the field of agriculture and animal husbandry. The purpose of drying grass is to remove excess moisture in the grass raw material, making it easier to package, transport, store, process and use. Therefore, there are many methods for drying grass, such as indoor stacking, open-air stacking, field drying method, grass rack drying method and drying equipment drying. Among them, the least drying time is to dry the grass using drying equipment. Currently, there are problems of insufficient drying time of fresh grass using drying equipment, which leads to incomplete drying. After the incompletely dried grass is packaged and stored, the moisture in the grass will cause mold inside the packaged grass pile, eventually causing the grass in half of the pile to deteriorate, which cannot be used as feed, resulting in a lower yield of processed grass and a series of after-sales problems, increasing the processing cost of grass processing enterprises.
