Abstract

A rice de-stoning machine using vibrating sieves was designed, fabricated with locally sourced materials and tested. The performance of the machine was evaluated and the results obtained showed that the feed regulator opening has significant effects on the de-stoning rate, de-stoning efficiency and rice losses. The best performance was obtained at feed regulator opening of 20 mm. Above 20 mm opening, the higher the feed regulator opening the higher the de-stoning rate and grain losses, and the lower the de-stoning efficiency. The average capacity of the machine was found to be 31.84 g/sec. and the average efficiency also was 98.3%.
