Study of electrization of powder skim milk during milk particle movement

Abstract

Electrization of particles of powder materials is a widely spread phenomenon that makes a practical impact on the functional efficiency of equipment designed for producing a broad range of processed disperse products (dry milk, flour, grain, etc.). The results of electrization tests of powder skim milk particles are presented. A mathematical model of inner and outer transfer of electric charge for a single powder skim milk particle is suggested. The studies on a specialized laboratory unit have made it possible to obtain data on triboelectric charging of particles in different testing conditions.
