Abstract

Maize shelling has been a tedious operation over the years; it takes weeks and causes pain and hand injuries, efforts have been made by artisans, welders and local fabricators at constructing some shelling machines for maize in Nigeria. This research work evaluates some locally fabricated maize shelling machines at Odo-Oba market along Oyo-Ogbomoso road, Oyo State, Nigeria. Structured questionnaires were used to assess the design features and challenges faced with the use of the machine while mathematical relations were used in evaluating the locally fabricated maize shellers in accordance with Nigerian Industrial Standard. It was obtained that petrol engines were used mainly as the power source of the machine at an average fuel consumption rate of 0.015 lit/min. The shelling efficiency ranged between 85.9 and 89.7 % with an average value of 88 %. The throughput capacity ranged from 318.4 kg/h to 400 kg/h with an average value of 360.8 kg/h. Main problems faced by machine operators include corrosion of machine parts, separation of kernels from cobs after shelling, packaging of kernels and cobs into bags after shelling and flying over of maize cobs during shelling. The maize shellers were of economic use and highly efficient though no prior design parameters and engineering properties of maize were considered before the fabrication of the machines, engineers are however tasked on the modification of the machine.
