Abstract: In this research, when designing the new model of the sieve, there are three important factors were introduced that affect the process of rice whitening and polishing. These factors are the length of the main shaft, the sieve diameter and the speed rotation of the main shaft. These three factors were introduced into the new design of the sieve through centrifugal force and its effect. The results showed that the practical side was identical with the theoretical side in the measurement of strain by stabilizing the strain gages at four angles (0, 10, 45 and 90). In addition, the new design gave a whiting ratio of rice higher than the old design which was 32.9% while to old sieve give the white ratio is 29.7%. And will also, prolong the life of mechanical parts of the machine better because the pregnancy will be less.
