The spacing between two adjacent groups of fixed grinding plates 514 is adapted to the diameter of the grinding rod 512. The movable grinding plate 513 is fixedly mounted on the grinding rod 512. The grinding rod 512 is arranged in two states: one is a grinding state in which food is processed by the movable grinding plate 513, and the other is a cleaning state in which the fixed grinding plate 514 is cleaned by a cleaning brush 522. It is worth noting that when food needs to be ground, the driving motor 610 can drive the turntable 511 to rotate clockwise, and when the turntable 511 rotates, it can drive the grinding rod 512 to rotate.

One end of the connecting pipe 521 passes through the end of the grinding rod 512 and is connected to the inner side of the grinding cylinder 200.

When the top block 528 moves out of the other end of the wedge block 5210, it can be reset by the pressing spring 527 and continue to slide with the annular guide groove 529 at the rear. When the movable grinding plate 513 needs to grind food, the output end of the driving motor 610 rotates clockwise to drive the turntable 511 to rotate clockwise. When the turntable 511 rotates clockwise, the cleaning brush 522 and the movable grinding plate 513 can be reset through the cooperation of the parts. When the turntable 511 rotates, it can drive the grinding rod 512, the connecting tube 521 and the cleaning brush 522 to rotate around the center of the turntable 511. When the connecting tube 521 rotates, its end can slide inside the annular tooth groove 524. When the connecting tube 521 slides, it can drive the gear 1 523 to slide inside the annular tooth groove 524. When the gear 1 523 slides, it can mesh and rotate through the annular tooth groove 524. When the gear 1 523 meshes and rotates, it can drive the connecting tube 521 to rotate. When the connecting tube 521 rotates, the cleaning brush 522 can rotate. When the cleaning brush 522 rotates, it can clean the food debris on the surface of the fixed grinding plate 514.
