Abstract

A motorized vegetable and fodder slicer was designed and fabricated. The machine consists of slicing blades, feed mechanism, support frames, collector and a1Hp gear electric motor as the driving power source. The machine has a capacity of 320kg/hr. During performance evaluation using Response Surface Methodology, it was found that the slicing efficiency increased proportionally with the speed of the machine and the moisture content of the sliced grass. The linear effects of speed of the machine and moisture content of the sliced grass significantly affected the slicing efficiency of the machine at 5% probability, (P≤0.05). The quadratic effects of the moisture content of the sliced grass and the interactions between the speed of the machine and moisture content of the sliced grass were also significant. These factors accounted for 91.06% of the variations in the slicing efficiency. The highest overall slicing efficiency of 89.57% was obtained when the moisture content of the grass material was 75% and the speed of the machine was 975rpm.
