When the rice enters the machine body 1 through the feed port 2, it will first collide with the rolling roller 414 and be clamped in the gaps between the ridges 415. By driving the ridges 415 to rotate through the rolling roller 414, the ridges 415 roll in the card slots on the rolling ring 411, so that the rolling ring 411 and the ridges 415 mutually roll and grind the rice, thereby performing pre-crushing treatment on the rice. Through the rolling pretreatment, the particle size of the rice can be initially refined, laying a good foundation for the subsequent crushing process.
