Study of Low Frequency Electric Field Treatment of Granular Materials

Abstract

The aim of the work is precise investigation of low frequency electrical field treatment of natural granular materials (seeds and grains). The components of electric field strength, current density, power losses and mechanical force along the surface of the grain have been obtained and estimated. The theoretical approach is based on AC conduction theory. The local models of each elementary grain region accounted simultaneously for the dielectric system dispersion and conductive system contributions. The field distribution has been studied using the finite element method and QuickField 5.6 software package.
