Abstract

The experiment was carried out during the agricultural season of 2010-2011 at Gemmeiza Agricultural Research Station, Gharbia Governorate, to evaluate the performance of a shelling and grading corn machine (Italian – manufactured) for SC10 and TWC 310 corn hybrids with corn moisture content of 15, 17, 19 and 21%. The machine parameters under investigation, to evaluate the shelling processing, were relative peripheral drum speed (6.28; 7.07; 7.85 and 8.63 m/s) and drum clearance (30, 40 and 50 mm). For grading performance evaluation, relative peripheral cylindrical screen speeds (2.63; 2.38; 2.13 and 1.88 m/s) and inclination angle of the cylindrical screen (zero; 4; 8 and 12 degrees) parameters were assessed. Shelling and grading efficiency, machine productivity, grain losses, grain damage and power requirement were estimated. The results indicated that the optimum parameters by using 25 kg feed rate at shelling drum speed of 7.85 m/s, drum clearance of 40 mm, cylindrical screen speed of 2.13 m/s, inclination angle of the cylindrical screen of 4 degree and grain moisture content ranging from 15 to 17 %.
