As rice is most consumable crop in world there is huge need of optimization in the rice milling process. In rice polisher most of the rice grains are break due to extensive force applied to grain to remove bran. Optimization in polishing chamber leads to reduction in the rice breakage. Shape of polishing chamber is more important parameter. As the polishing rotor is prone to wearas milling progress, hence the consideration of easy replacement and minimum downtime is another important factor. Cylindrical polishing chamber is always preferred over conical chamber. Second parameter is the rotating speed of polishing wheel. Peripheral speed more than 600m/s is mostly preferred; however the broken percent of rice kernel nearly doubles when Rotating speed is increased from 600 to 1200 rpm.
