【 摘 要 】

Development of a small maize shelling unit necessitates a study of factors affecting its shelling performance. In this study, the threshing type used is a rasp-bar type. On drum four rows with a diameter of 0.3 m, the design parameters of which include concave clearance. The peripheral speed of the drum, and grain moisture content; which affect the shelling efficiency and the amount of grain breakage. The maize used to be the CP 201 variety. The feed rate was controlled at 960 kg.hr-1. It was found that concave clearance and grain moisture content significantly affects the shelling efficiency and grain breakage at P1 and grain moisture content not exceeding 14%.
