| Summary: | Dielectric properties are important characteristic parameters in the microwave-assisted application of hygroscopic agricultural media. In order to expand the application of electromagnetic wave in the drying of core-shell agricultural products, a numerical model is established by discrete element method, finite element method and average energy method. The internal correlation between the thickness, volume fraction, conductivity, and dielectric constant of each component with the efficiency dielectric properties of core-shell agricultural materials is simulated and obtained. The results can provide the data for the development of electromagnetic drying process of agricultural products and the setting of process parameters of drying equipment. This simulation model is suitable for the analysis of RF range.
