Straw feed: It can be used as the raw material of silage or ammoniated feed for animal husbandry.

The working principle of the straw dryer: The straw first enters the inner layer of the rotary drum from the feeding device to realize downstream drying, and is continuously picked up and scattered under the inner layer of the copy board to realize heat exchange in a spiral way; The other end of the inner layer enters the middle layer for countercurrent drying, and is continuously and repeatedly lifted in the middle layer, in a two-step forward and one-step backward mode; then the middle layer can fully absorb the heat emitted by the inner layer roller and absorb the heat. The heat of the middle drum also prolongs the drying time, and the material achieves a better drying state here. Finally, the material travels to the other end of the middle layer and falls into the outer layer, and travels in a rectangular multi-loop way in the outer drum. The material that achieves the drying effect quickly travels and exits the drum under the action of hot air, and the wet straw that does not achieve the drying effect cannot be quickly due to its own weight. travel, and fully dry in this rectangular plate, thereby completing the entire drying process.
