Abstract
In the Republic of Buryatia, it is relevant to improve the process of barley grain material cleaning due to its unsatisfactory quality. Contamination with other crop and weed seeds (wheat, oats, rye, wild oats, Tatar buckwheat) is above acceptable levels. It has been confirmed that the available technical means and methods for grain cleaning are not effective enough to separate these impurities from the processed material. The most hard-separable impurity of barley grain among weed seeds is wild oats. It has been proven that small seeds of this contaminant are sifted out of the grain on the undersowing sieve of the grain cleaning machine with openings 2.4–2.6 mm wide. Large seeds of wild oats are separated from the grain as long impurities when it is passed through a grain cleaning machine with a cylindrical working element with 11.2 mm cells with the position of the receiving edge of the chute at an angle of 55–60о to the horizontal diameter of the cylinder. It has been established that when processing seed grain on an air-sieve machine and a grain cleaning machine with a cellular cylinder, the completeness of the separation of wild oats is 0.81–0.97 and a sufficiently high seed yield is ensured (61.2–81.3%). Processing barley grain according to the proposed scheme allows obtaining high-quality seeds.
