Microwave heating in industry

The article presents an analytical review of publications highlighting the possibilities of innovative application of technologies using the energy of the electromagnetic field of ultrahigh frequency (EMF microwave) in various industries. As the analysis of technologies based on the action of the electromagnetic field of the ultrahigh frequency range shows, they are already used to solve a variety of problems: from sterilizing compotes and drying lumber to producing thermally expanded graphite and the use of these technologies in medicine. This article highlights the main advantages of using the microwave electromagnetic field, regardless of the scope of its practical application. The implementation of innovations, based on the energy of the electromagnetic field of the microwave range in the technological schemes of various industries will reduce energy consumption and improve the efficiency of the technological processes themselves. This implementation will ultimately lead to increased productivity and lower capital and operating costs, it will allow to significantly modernize production in terms of reducing energy consumption per unit of the processed product, and in terms of improving the quality of raw material processing. Possible deficiencies and their solutions in production processes are described. A significant obstacle to the intensive implementation of these technologies is the fact that the nature of wave propagation in different materials, under different initial and final conditions, can differ significantly from each other. This, in turn, implies careful design of the hardware component (emitters and chambers) as well as finding the optimal process parameters (temperature and heating rate, installation power, intensity, frequency and electromagnetic field intensity).
