| Summary: | The purpose of the research is to modify the sorghum polishing machine TEP-2, previously developed by Agriculture Industrial Engineering and Management Department of Padjadjaran University. The specific aims are to improve and simplify the polishing process, such as to reduce the percentage of crack and unclean sorghum as well as to increase the clean sorghum. The capacity of the <br />

The modified sorghum polishing machine TEP-3 is successfully designed and built. Research is conducted to determine the influence of speed and gap between polishing rotor and the sieve. Rotation speed of 1300, 1500, 1700 rpm and gap of 10, 12.5 and 15 mm are chosen to determine the optimum performance of the polishing machine. Depending of the speed and the gap, the percentage of clean, unclean and crack sorghum are varied from 72% to 93%, 2.02% to 25.8% and 0.79% to 24.3% respectively. The capacity of the polishing process is also varied from 24 kg/hour to 68 kg/hour. The best setting of the gap which produced the most cleanest with less crack and unclean sorghum is 15 mm at 1500 rpm. |
