Development of a Rice Threshing Machine

This paper deals with the development of a rice threshing machine. Available evidence suggests that the mode of threshing rice in the rural areas in Nigeria is by traditional use of hand beating of the paddy. This method is time wasting, energy sapping and often the grains are broken. The developed rice thresher 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. From the design calculation, the total power required to comb off grains from stalk is 267.04 W and to be driven by a 1.5 Hp electric motor
