| Abstract | ||||
| A power-operated corn sheller was manufactured to investigate the effect of corn moisture content, drum rotary speed on the percentage of damaged kernels, undamaged kernels, losses of kernels as well as shelling efficiency and machine productivity. The experiments were conducted at four levels of kernels moisture content of 12,2, 13.3, 14.5and 16 % and four drum rotary speeds of 220 , 280, 340 and 400 rpm ( 23.02, 29.31, 35.9 and 41.9 m/s). The results indicated that, increasing drum speed lead to increase each of damaged kernels, losses kernels and machine productivity. On the other side, increasing drum speed tends to decrease the undamaged kernels and machine efficiency. The least value of damaged kernels (1.5%) and the highest values of undamaged kernels (98.5%) and machine efficiency (96.3%) were obtained at moisture content of 13.3%. While increasing moisture content lead to increase the losses kernels and decrease machine productivity. | ||||
