Design and Construction of Rice De Stoning Machine

A rice de stoning machine was designed, fabricated and evaluated for performance. The de stoning machine will utilize vibrating motion to further separate the rice grains from the impurities. The vibration causes the rice grains to move in a specific direction, while the heavier impurities remain stationary. Mild steel was used in the construction of the machine. The machine is driven by a 2Hp electric motor with 1103W required power. Standard equations were used to determine the dimension of the pass and optimization of machine parameters such as air flow rate and vibration frequency. The effectiveness of the de stoning machine will be evaluated by testing its performance with different masses of rice samples and impurities. The machine has a capacity of 436.16Kg hr and an efficiency of 90.03 . A. E. Ilechukwu | S. E. Abonyi | A. E.
