摘要

Taro (Colocasia esculenta) has been a part of traditional cuisine for centuries. Taro contains an alkaloid-containing mucus just beneath the peel that causes itching when it comes into contact with the skin. Manual peeling can easily lead to itchy skin and the long exposure of peeled taro to air causes oxidation, turning the taro yellow and altering its color and flavor. To address the itching problem, a prototype peeling machine was developed. The taro peeling machine mainly comprises a peeling groove, multiple groups of rod-shaped hard brushes (brush rollers), a water spraying mechanism, a sewage outlet, a control system, a frame, and a speed changer device. In this work, a tuber peeling machine was developed and optimized for mother corm peeling. The optimized peeling conditions were found to be the rotating disc speed of 102 rpm, peeling duration of 87 s, and a batch load of 1.7 kg, which yielded a peeling efficiency of 93%, material loss of 8.3%, and peeling effectiveness of 84% were obtained. The peeling machine is designed to peel taro corms of different shapes with higher peeling efficiency and is ideal for small to medium-sized industries. The developed machine reduces the labor intensity, minimizes waste, and enhances the peeling efficiency.
