Effective Parameters of Broken Rice During Paddy Hulling Using Rubber Roll Huller

M. Payman, I. Bagheri, M.R. Alizadeh and R. Roohi    

Abstract: One of the effective parameters on broken rice while hulling is the way in which the machinery like the paddy huller work. With regards to the nature of paddy hulling operation in the milling process some of the rice quality losses occur at this stage because the hulling operation is mechanical and consist of different stresses. Three varieties of Binam, Khazer and Alikazemi were used for the study. The levels of moisture content used in the tests were 9.5-11, 11-12.5 and 12.5-14% wet. The linear speed difference was chosen so that the linear speed of rollers was in the range of 200 to 275 m min-1. The results showed that the main effects of all parameters studied were significant on the amount of rice breakage. The main effects such as linear speed differences of rollers m min-1 and variety were significant on the hulling index and the counter effects of linear speed differences of rollers and m.c. were also significant on the hulling index but did not have a significant effect on the amount of rice breakage. The highest hulling index for the three varieties considered occurred with a roller linear speed difference of 236.7 m min-1 and the least rice breakage occurred when the roller linear speed difference were 229.3 m min-1. Under similar conditions the lowest rice breakage occurred with the Binam variety. The amount of rice breakage in the hulling process for the Alikazemi variety was significantly higher than the other two varieties. The highest broken rice in the hulling process for Alikazemi occurred at moisture content of 11-12.5% and for the other two varieties at 12.5-14%.
