Dielectric separation

Abstract

This article describes the dielectric sorting methods, the pros and cons of existing dielectric sorting machines. At the cotton ginning plants of the Republic of Uzbekistan, the widely introduced KSM-1-15 sizing and sorting machine is used to sort bare cotton seeds. Its disadvantage is that during prolonged operation, the holes of the perforated vibrating gratings become clogged with seeds, and the calibration process deteriorates.With this sorting, both small seeds with a very low and high specific gravity, and a part of seeds with a high weight of 1000 seeds, but a relatively low specific gravity, go into marriage. Some of the seeds are damaged. The sowing fraction of seeds with the same size retains a pronounced heterogeneity in terms of nutrient supply and maturity Therefore, methods and devices are needed that are capable of separating seeds according to the combination of physic-mechanical and chemical-biological properties of seeds. These requirements are met by the dielectric method of sorting seeds in an electric field.
