Alwan-Alsharifi , S. K., A. Arabhosseini, M. H. Kianmehr and A. M. Kermani, 2017. Effect of moisture content, clearance and machine type on some qualitative characteristics of rice (Tarm Hashemi) cultivar. Bulg. J. Agric. Sci., 23 (2): 348–355

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 signifi cantly better than the Yanmar type machine in all studies properties. While clearance 0.8 signifi cant superiorly than two levels 0.4, 0.6 mm in all studies properties, In addition moisture content 10–12% is superior signifi cantly 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 signifi cantly 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.

Key words: machine, grain moisture, clearance, husking, quality, rice
