Effects of louver inclination on threshing unit losses of an axial flow rice combine harvester (Thai)

Abstract

The objective of this study was to determine the effects of louver inclination on threshing unit losses of an axial flow rice combine harvester. The results indicate that the losses linearly increase when the louver inclination decreases from 78 to 68 degrees, but the losses rapidly increase when the inclination is lower than 68 degrees. It was also found that the effects of the louver inclination were higher for a higher feedrate. Thus the louver inclination should not be less than 68 degrees.
