The paper presents the optimization of the dielectric position inside a microwave installation created for processing dielectric materials – seeds/granular products – using design of experiments (DOE) with the main purpose of making the power transfer towards the dielectric more effective. Running simulations for various input data with the commercial Comsol Multiphysics software and using the experimental methods available in the statistical and data analysis software Minitab, we intend to obtain the optimal position of the dielectric inside the applicator for certain specified conditions.
