Abstract

The microwave-convective processing of grain can be used in processes of drying, disinfection, and preparation for feeding in agriculture. These processes are characterized by high-energy intensity, which makes this work relevant to current technical level. The article describes disadvantages of the existing methods of research of dielectric properties in the study of pseudo-fluidized and suspended layer by the microwave field. The article describes the laboratory installation and the experiment on the study of the suspended layer of grains of different cultures. The results of the experimental studies to determine the factor of dielectric losses of the material undergoing microwave treatment are described. The results obtained for different densities of the material match the general trend but differ significantly in their levels. Dynamics of change of dielectric materials depending on the density of the layer is similar for different crops.
