Fractioning of grain materials in the vertical ring air channel during electric field imposition.

Abstract

The problem of obtaining high-quality (commercial) food grains and seeds of cereals and oilseeds can be solved by using fractional technology for post- harvest processing of grain. The shortcomings of existing machines can be eliminated if, when a particle moves in an ascending air flow, the orientation of its axes of inertia in the channel space is stabilized. One of the effective ways of directional orientation of elongated grains can be the imposition of a stable electric field on a two-phase flow (grain-air). The article theoretically summarizes and proposes a new solution to the scientific problem of increasing the efficiency of the process of separating grain material according to the complex of aerodynamic and electrophysical properties of individual components of the grain material.
