The Development of a Household Rice Milling Machine

Abstract

This research aimed to develop the color brown rice milling machine for using in household and to test the performance of the color brown rice milling machine that can be used with both brown rice and white rice.The power consumption was 90 watts using a voltage of 220 volts. The advantages of this milling machine were inexpensive, not complicate process, easy to repair and maintenance. The speed of the screw was studied to find the optimum rice milling. The performance of brown rice milling was tested with two rice variants, RD 31 rice and jasmine rice. The results found that the suitable speed of the spiral for rice milling was 2300 rpm with average weight of RD 31 brown rice breeder 645 g/1000 g of starting rice. The average weight of broken rice was 35 g/1000 g of starting rice. The rice milling rate was 7.30 kg/hour. Moreover, the average weight of jasmine rice milling was 579 g/ 1000 g of starting rice and the broken rice average weight was 37 g/1000 g of starting rice at milling rate of 7.25 kg/hour.
