THE EFFECTS OF THE WORKING ORGANS OF A VIBRATORY SEPARATOR ON WINTER WHEAT AND RYE DAMAGE AND QUALITY

Abstract

The paper highlightens the issue concerning the effects of the working organs of a vibratory separator on macro- and micro- damaging of winter crops seeds as well as on their quality. The goal of the research was to reduce the grain crops seeds damaging and to improve their quality at the technological processes stages of their preparing, starting from harvesting to sowing, by means of developing the highly productive and efficient technologies as well as by technical means and engineering developments. The method of mathematical simulation of the processes of bran processing as well as of preparing a high quality seed grains of wheat and rye were reasonably used in the process of the research. Theoretical calculations, differentiation, integration and graphical dependences show that the experimental, operational and laboratory results , under condition of using rubber, plastic and other materials for making or covering the working organs of a vibratory separator, contribute to reducing grain deformation, damaging, micro damaging in particular, and to quality improvement. It has been discovered that at the revolutions of a disk distributor of an air separator which moves at a starting speed of ω up to 6 rad. с-1 and when the grains 0.03-0.06 gr in weight with a transverse diameter up to 5-6 mm get into it, their deformation and microdamaging is minimal, that contributes to a high grain quality. Further research on improving the seeds quality indices by reducing grain damaging in the process of its preparation on the vibratory separator must be conducted in the interaction and in interconnection with other working surfaces and with their influence on deformation, micro-damaging, quality, yielding and grain gross output
