| Abstract | ||||
| The aims of the present research are to develop and evaluate tractor-trailed rice-milling machine. The factors affecting the performance of the developed milling-machine feeding rate, drum speed, grain moisture-content were studied. The performance measurements were productivity, total machine cleaning efficiency, total grain-losses, power required, specific energy and operational cost. The experimental results reveal that the highest values of productivity and machine efficiency were 1.35 Mg/h and 97.3 %. Meanwhile, the minimum required power and the specific energy were 16.82 kW and 14.55 kWh/Mg respectively for tractor-mounted rice milling machine after development, The minimum operating cost was 32.71 L.E/Mg These values were achieved under conditions of feed rate of 1.25Mg/h, drum speed of 800 rpm and moisture content of 14%. | ||||
