Short summary
To improve the rate of broken rice in a rice mill machine, experiment and simulation work of the rice milling process was employed. Results showed that the increasing sieve edges caused a decreasing compressive force and increasing milling time, resulting in the maximum rate of broken rice and milling degree in the octagonal sieve. The uniformity of the milling process could also be optimized by adjusting the geometries and numbers of the convex ribs of the rotating roller.
