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.
Keywords: Maize, threshing unit, shelling unit
