In the last few decades, the related studies in the literature became rather common while there are certain industrial applications. The innovative feature of MW processing lies in the volumetric heating with possible temperature uniformity within the product compared to the conventional thermal processing of canning and aseptic processing. However, non-uniform temperature distribution due to the evolution of electromagnetic field within the cavity and the sample and local overheating are still the common problems especially for the industrial scale up. While the geometry of the cavity and the samples affect this temperature uniformity, dielectric properties also play a significant role with their effect on the penetration depth. The movement of the sample within the cavity is currently the major approach for uniform temperature distribution. Therefore, in this study, the interaction between geometrical features and the evolved electromagnetic field due to the continuous center and off-center rotation within the cavity were focused. Depending upon the geometrical features of the sample, continuous off-center rotation was determined to be rather significant in achieving temperature uniformity and preventing the local heating problems over the surface of the samples.
