Abstract

Cocoyam is cultivated mainly for its edible cormels. In spite of its great potential as a cheap raw material, the
processing operations are still largely performed manually. Some of the equipment already developed for
mechanizing the postharvest operations require further modifications and performance optimization. This study
therefore, aimed at developing and evaluating the performance of a cocoyam cormel peeling machine with a view to
reducing the drudgery involved in manual peeling. A cocoyam cormel peeling machine was developed using locally
available materials. The machine consists of the main frame, hopper and outlet gates, two abrasive concentric
drums (one stationary and the other rotating) and blower. Performance of the machine in terms of capacity, peeling
efficiency and peel-cormel weight proportion were evaluated for soaked and unsoaked cormels. The average
machine capacities were 188.4 and 188.9 kg/h for soaked and unsoaked cormels, respectively. The peeling
efficiencies ranged between 55.5 and 87.5% while the peel-cormel weight proportions ranged between 15.3 and
22.9%. The peeling efficiency was higher for soaked cormels than unsoaked ones. The developed cocoyam cormel
peeling machine helped in reducing the drudgery associated with its peeling operation while soaking as a form of
pretreatment was recommended before peeling the cormels for better performance.
