| Abstract | ||||
| Mechanical shelling maize is an important operation in all over the worldwide to decrease the number of labors, time and reduce cost. The Chinese machine was modified and operated by an electric motor which was evaluated at different shelling drum speeds of 1000, 1400, 2000 and 2800 rpm (4.45, 6.23, 8.9 and 12.46 m/sec), four different rear cone clearance of 25, 30, 35 and 40 mm and four different tilt angles of drum 3, 7, 12 and 16Ëš at constant moisture content (MC) of 13 % and constant front cone clearance of 70 mm. The results showed that at an optimum drum speed of 2000 rpm, the productivity of maize sheller was 497 kg/h, grain damage of 0.28 % shelling efficiency of 99.25 %, Specific energy requirement of 3.38 kW h/t and operating cost of 37.97 EGP/t at the constant MC of 13 %, constant front cone clearance of 70 mm, rear cone clearance of 35 mm and recommended tilt angle of 12â´°. The study provided information and baseline knowledge for improving the shelling maize to obtain high shelling efficiency, save cost, time and labors during shelling maize. | ||||
