Research of the character of distribution and electromagnetic field in the field of action of an experimental microwave ventilation unit for construction of heat treatment systems

At the modern level of scientific development, the technology of post-harvest processing of grain and feed using a microwave field of ultra-high frequency (UHF) is widely used. It allows you to solve several problems at the same time: disinfection and drying of grain, pre-sowing treatment of seeds, preparation and disinfection of feed. Serious limitations in the implementation of microwave technologies in drying and disinfection of grain are the uneven distribution of the microwave field over the thickness of the grain layer and the operational reliability of magnetron power supplies. Providing a more uniform distribution of the microwave field in the processing area is possible by improving the design of the waveguides. In this work, a computer model of the working area of a laboratory facility has been developed, containing 2 microwave power sources for processing the grain layer, and the electromagnetic field distribution has been modeled. Based on the simulation results, an experimental model was developed with variable parameters of the product pipeline. Further, the planning and implementation of experimental studies of the study of the propagation of the electric field strength in the product pipeline of the installation filled.
