ANALYSIS OF GRAIN PROPERTIES IN RELATION TO THE PROCESS OF SEPARATING GRAIN AFTER HARVESTING BY THE TOW METHOD

One of the most important stages of grain harvesting and processing is its post-harvest processing. The quality of the post-harvest processing determines its safety, as well as its quality characteristics. The article considers the properties of a grain heap that affect the separation process. Wheat grain was analyzed for the amount of weed and grain impurities of varieties: "Gift to Crimea" and "Premier", harvested by a new unit for harvesting by the method of combing on the vine. It has been determined that the amount of weed in the grain after the unit is 16-17%, which is 5-10% more than after traditional combine harvesting and a stripping header aggregated with a combine. The size of the weed was also determined by sifting through a set of sieves with a diameter of 6 mm, 4 mm, 3.5 mm, 3 mm, 2 mm, 1.5 mm.
