Microwave assisted vacuum drying offers never questioned advantageous and it is getting more and more popular lately. In spite of its uniqueness there is a rightful resistance and mistrust because the temperature distribution of the workload is far from being homogeneous as a result of the existing inhomogeneous electromagnetic field. The aim of this study is to survey the heat thus field distribution in the workload to prevent local overheating that endangers the quality of the pharmaceutical product. Thermography as a non perturbing thermometrical method was used to map the heat distribution in the workload. To get a 3D information Teflon layers were used to form cross-sectional and photogenic surfaces about the dusty blend and a purpose-developed software to evaluate qualitatively the IR pictures.
