Abstract: This research includes the using of two types of machines (Satake and Yanmar),under three levels of clearance between cylinders 0.4 , 0.6 and 0.8 mm and three levels of moisture content 10-12%, 12-14% and 14-16%. Are considered for the test cracked grain percentage, brown rice percentage, husking efficiency, head rice percentage and broken rice percentage. The results indicate that the Satake type machine is significantly better than the Yanmar type machine in all studies properties .While clearance 0.8 significant superiorly than two levels 0.4, 0.6 mm in all studies properties, In addition moisture content 10-12% is superior significantly than two levels 12-14%, 14-16% in all studied properties. The overlap between the Satake type machine and grain moisture content 10-12% superior significantly and also overlap between the Satake type machine and clearance 0.8. in all studied properties. The best results have come from the triple overlap among Satake type machine, grain moisture 10-12%, and clearance 0.8 mm in all studies properties.
