Technical Field
[0001] The utility model belongs to the technical field of feed production equipment, and in particular relates to drying equipment for natural plant feed production. Background Art
[0002] The raw materials of natural plant feed include plants, and the plants need to be crushed during the production process. However, fresh plants have a high water content, which is not conducive to crushing, so they need to be dried. The patent document with authorization announcement number CN 204923699U discloses a plant feed dehydration device, including a shell, a feeder, a pressing cylinder and a fixing device, wherein the pressing cylinder is arranged in the upper inner part of the shell, the fixing device is fixedly installed at the front end of the pressing cylinder, a buffer layer is arranged between the fixing device and the pressing cylinder, the interior of the pressing cylinder is a pressing chamber, a spiral pressing rod is arranged in the pressing chamber, a pressing screw is arranged on the spiral pressing rod, a pressing discharge port is arranged at the left end of the pressing cylinder, a liquid discharge port is arranged below the pressing cylinder, and the liquid discharge port is connected to a liquid storage box arranged below the pressing cylinder. The patent first squeezes and removes water from the raw material through the pressing cylinder, and then uses the drying cylinder to heat and dry the raw material, thereby improving the drying efficiency of the plant raw material. However, since a variable diameter feeding screw is used for squeezing in the pressing cylinder, it is not suitable for drying plants, because for longer plants, there is a problem of entanglement on the feeding screw, and for larger plants, there is a problem of poor drying effect and low efficiency. Therefore, a natural plant feed production drying equipment is needed to solve the above technical problems. Utility Model Content
