Abstract : This paper deals with the development of a grain separation machine and presents a review of former needs/approaches. Available evidence suggests that the grain separation machine in the rural areas by traditional use of hand beating of the paddy (grains). This method is time wasting, energy sapping and often the grains are broken. The developed grain separator machine has the ability to winnow the premature grains and leaves, which are often lighter, thus, leaving aside the massy grains that, will be collected. It is also capable of reducing time wastage, reduction in breakage of the grains and separation of the stalk from the grains.
