ABSTRACT

A low-cost corn shelling and threshing machine was designed and developed using locally sourced standard materials to reduce drudgery and improve hygiene. The machine consists of a hopper, threshing spikes and threshing rollers, shelling roller and shelling conveyor, a blower, a 3 HP single phase electric motor. This machine threshes, shells and separates the cobs from the grain. The use of locally available materials made the cost of the machine very low and affordable. The results of its performance test gave 95.305% and 37.4kg/h as its efficiency and throughput capacity respectively. The mass loss as a result of left over in the machine or the mass damaged was gotten as 0.122g. The design has been found to have the most economical and optimum technical and operational characteristics, such as replacement ability, service life, simplicity and ease in productivity. With this machine however, the tedious challenge encountered in manual shelling and threshing methods will be eliminated.
