A grinding mechanism is provided on the grinding cylinder 3, and a cooling mechanism is provided between the base 1 and the grinding cylinder 3. The red seedling rice is poured into the grinding cylinder 3 through the feed hopper 4. After the red seedling rice contacts the grinding mechanism, the outer husk, pericarp, seed coat, outer endosperm layer of the red seedling rice will be ground off, leaving the inner endosperm to flow out from the discharge pipe 12. A large amount of heat will be generated in the process of grinding the red seedling rice. The cooling mechanism can reduce the temperature of the grinding cylinder 3 to avoid the temperature of the red seedling rice rising during the grinding process, which will easily cause the loss of nutrients in the red seedling rice and cause waste.

The motor 5 can drive the grinding roller 6 to rotate inside the grinding cylinder 3. When the red seedling rice inside the feed hopper 4 passes through the partition layer 9 and contacts the grinding roller 6, the mutual friction between the grinding roller 6 and the red seedling rice will grind off the outer husk, pericarp, seed coat, outer endosperm layer, etc. of the red seedling rice, and then it falls from the discharge pipe 12 to the outside for discharge. The discharge pipe 12 is provided with a butterfly valve to control the discharge of the red seedling rice.
[0022] One end of the grinding cylinder 3 is detachably connected to a sealing cover 7 by bolts, and the other end of the sealing cover 7 is hinged with a movable cover 8. A snap lock is provided on one side of the movable cover 8, and sealing rings are provided on one side of the sealing cover 7 and the movable cover 8. The snap lock can control the opening and closing of the movable cover 8, making it convenient for people to clean the husk of the red seedling rice inside the grinding cylinder 3. The sealing ring can fill the gap between the grinding cylinder 3 and the sealing cover 7 and the movable cover 8 to ensure the sealing between them.

The interior of the pipe 10 is connected, and cold water is added thereto through the water injection pipe on the top of the water tank 13. The water pump 19 cooperates with the water pipe 20 to transport the cold water in the water tank 13 to the internal partition layer 9 of the grinding cylinder 3, so that the cold water flows inside the partition layer 9. The heat generated during the grinding of the red seedling rice will be transferred to the inside of the partition layer 9, and this heat will be absorbed by the cold water and then discharged from the outlet pipe 11 to the outside of the partition layer 9, so as to cool the grinding cylinder 3 and prevent the loss of nutrients in the red seedling rice due to excessive temperature.
[0024] Two fans 17 are installed on one side of the base 1, and auxiliary cooling mechanisms are arranged inside the two fans 17. One end of the water outlet pipe 11 is connected to one end of the auxiliary cooling mechanism.

The U-shaped series structure of the copper tube 15 can extend the time that the water stays in the copper tube 15 area. The copper tube 15 will transfer the heat energy in the water to the heat dissipation fins 16, increasing the contact area with the space, so that the water cooling effect is better. The cooled water is transported back to the water tank 13 for recycling to save water resources.
