The invention discloses a vertical wine stock pulverizing device. The vertical wine stock pulverizing device comprises a machine body. A lower processing box is arranged on the inner side of the machine body. An upper processing box is mounted at the upper end of the lower processing box in a matched mode. A plurality of supporting springs are arranged on the outer side of the lower processing box. A driving motor is mounted at the bottom of the lower processing box. A plurality of crushing cutters are mounted on a crushing shaft. A conical guide plate is arranged at the bottom of the side face of the lower processing box. An upper feeding pipe is mounted at the top of the machine body. A lower feeding pipe is mounted at the top of the upper processing box. The upper feeding pipe communicates with the lower feeding pipe through a corrugated guide pipe. An air heater is arranged on the outer side of the machine body. A ring pipe is arranged on the outer side of the driving motor. A plurality of jet heads are mounted on the upper side of the ring pipe. The air heater communicates with the ring pipe through an air conveying hose. Through the vertical wine stock pulverizing device, wine stock can be rapidly pulverized, and the vertical wine stock pulverizing device is novel in structure, reasonable in design and easy to popularize.
