Abstract: 

Cleaning wheat of impurities post-harvest is necessary to prepare the wheat seed for storage, production, and consumption. This study investigated three machines to clean impurities from wheat samples with the greatest efficiency by wheat variety in northern Khuzestan province. The three cleaniing machines were the A.R. S5000 (Iran), Cimbria (Denmark) and Goldsaat G.S.IOO (Germany). The study was a completely randomized factorial design for machine type, amount of feed (70% and 95% of machine nominal capacity), airstream level (three levels) and wheat seed type (Chamran, Virinak, Behrang). The effect of these factors was studied on the total efficiency of the cleaning machines. The base sieve size was defmed by wheat variety and installed as the upper and lower sieves every machine. The results of statistical analysis showed the Cimbia machine had the greatest cleaning efficiency (86.72%). The A.R. S5000 and Goldsaat had 80.64% and 81.59% total efficiency, respectively. The impurities in the Behrang variety were cleaned more efficiently (84.31 %) than the Chamran and Virinak varieties. As the amount of feed decreased and the amount of airstream increased to terminal velocity the total efficiency of the cleaning increased.
