Design and Construction of Multipurpose Grating Machine for Household and Micro/Small-Scale Business with Electric Motor

Abstract

The accuracy and speed of preparation of raw materials was one of the keys to the success of a food processing business during the Pandemic and digital era. Mini multipurpose grating machine that was effective, efficient and hygienic was a tool for processed food production needed by micro and small scale businesses to win the competition in the era of on-line business. The purpose of this research was to design a mini multipurpose grating machine that can be used by micro and small scale processed food producers with a compact and simple design, made of food grade stainless steel material, and easy to maintain. This design produced a mini multipurpose grating with specifications of 1,550 mm in length, 900 mm in width, 2,100 mm in height and ±3 kg in weight. The small main drive motor was the advantage of the machine so that it is light and compact which can be placed under the grater cylinder. The results of the performance test showed that the working capacity of grating for coconut was 2.56 kg/h with an efficiency of 95.54%. The mini multipurpose grater machine was easy to carry and can be used for coconut, cassava, sweet potato, carrot, ginger and other similar commodities, which were used as raw materials for processed food on a micro and small scale.
