Design, Development, and Performance Evaluation of a Motorized Cassava Peeling Machine

This study focuses on the design, development, and performance evaluation of a motorized cassava peeling machine, constructed using locally sourced materials. The machine features an abrasive peeling drum, a hopper, a mild steel frame, and a pulley system, all powered by a 2 hp single-phase induction motor. During performance tests, the machine demonstrated an average throughput capacity of 75.54 kg/hr. and a peeling efficiency of 88.33%. Statistical analyses using factorial experimental designs revealed that machine speed and day after harvest had significant impacts on peeling efficiency (p = 0.0199) and throughput capacity. The optimal performance was observed when cassava tubers were processed 1 day after harvest using a 2 mm grater, maximizing throughput. While the interaction between the day after harvest and grater size significantly affected throughput capacity (p = 0.0213), the interaction between machine speed and grater size was insignificant. ANOVA results confirmed the reliability of the regression models, with model validation ensuring normality and constant variance. This locally fabricated machine offers an affordable and efficient solution for small to medium-scale cassava peeling, improving productivity and reducing manual labor.
