Effect mechanical on rice husking for test two machines

Abstract

The experiment was conducted to evaluated Effect of husking process on the rice productivity for two cultivars Mashkhab (M-33) and Jasmine (JA). Two types of machines (S-KB40 and Y-ST50) were tested at three ranges of clearance between cylinders of 0.5 mm, 0.7mm and 0.9mm for two rice cultivars of JA and M-33. The experiments were carried out in a factorial experiment under complete randomized design with three replications,  the study was of the characteristics following machine productivity, power required and husking efficiency, and the qualitative characteristics for two rice JA and M-33 cultivars included, broken rice ratio and head rice . The results showed that S-KB40 machine is better than Y-ST50 machine in all studied conditions for both two rice JA and M-33 cultivars. The clearance 0.9 was significantly superior to the other two levels of 0.5 and 0.7 mm in all studied condition except the husking efficiency for both two rice JA and M-33 cultivars.
