Abstract

A prototype motorized cassava tuber-shredding machine was developed and evaluated. The machine performed well in the shredding of parboiled cassava tubers of NR87184 variety at moisture content of 63.5%. The efficiency ranges from 67.80% to 72.2% while the throughput ranges from 13.09 to 27.02kg/hr when operating at 100 rpm while at 50rpm, the efficiency of the machine range from 60% to 75.2% and throughput ranged from 11.37 to 21.41kg/hr. Generally, the steaming time affected the efficiency, throughput and the length of shreds. The optimum performance was shredding at a speed of 50rpm and steaming time of 10minutes, which gave a longer shred length of 76mm with a width of 2.18mm and efficiency of 75% but with a throughput of 21kg/hr. For optimum performance at 100rpm, throughput of 27.02kg/hr and efficiency of 70.3% was obtained at a boiling time of 10mins, with average shred length of 54mm and width of 2.16mm.
