Design and Construction of a Rubber Roller for Garlic Peeling Machine from Natural Rubber

Abstract

This research aims to design and construct a garlic-peeling roller by using natural rubber as mainraw material. This makes the roller more flexible and reduces the breaking rate of garlic petal. Moreover, theroller is also designed to have various patterns on its surface to find the most suitable and most effective onefor peeling garlic. The roller is designed to have 3 patterns: convex pattern, saw tooth pattern, and rectangularpattern in order to compare with the smooth pattern roller. It has been found that the natural rubber can beused to press on garlic-peeling iron roller and can be used for garlic peeling. All 3 types of the constructedrollers can solve problems of broken garlic petal during use with a percentage of damage 2.5 %. The patternused on the roller can increase effectiveness of garlic peeling by 25% compared to the smooth pattern roller.
