The aim of the study is to increase the efficiency of the operation of the facilities for the thermal processing of raw materials by exposure to electromagnetic radiation and the improvement of their main working organs that ensure the improvement of the quality of the product with the least operating costs. The work differs from existing studies by methodical generalization of the electrodynamic system with various design execution of the working chamber, ensuring the flow of the technological process of heat treatment and disinfection of raw materials due to repeated exposure to EMP. Because of the design features of the bulk resonators, the units have specificity in the principles of operation, in the methods of designing the nodes and all the elements of the energy transfer from the emitter to the raw material as a whole. In a constructive respect, the electrodynamic systems of microwave generators differ from existing ones by combining mobile resonator and beam chambers located in a toroidal shielding body. In microwave technology, this method of energy transfer constitutes an independent field of study. In this case, it is possible to detect the dynamics of the process taking into account the time variation in the dielectric and thermal physical parameters of the raw material, calculate the configuration and dimensions of the cavity resonator in accordance with the wavelength and the critical electric field strength, determine the number of sources and their location in the working chamber.

The result of the research conducted shows that cargo transportation is one of the components of successful activity and efficiency of the enterprise in the agro-industrial complex. The collected data have shown that economic efficiency is influenced by many process parameters. The data collected allowed to make a conclusion that. For the optimization of cargo transportation, the AIC needs careful choice of the number, type and brands of vehicles, taking into account the type of activity of the enterprise, its production volumes and range of cargo transportation. When collecting the data to choose the type and construction of motor vehicles with regard to the operating conditions it was found out that it is necessary to consider many parameters: the type of cargo, the nature and volume of transportation, the mode of operation of motor vehicles, organization of transportation, road and weather conditions. For this purpose, the following information was specified: necessary parameters of the cargo taking into account volume and weight, the choice diagram of the vehicle based on the properties of the cargo. The data received which were used for choosing are provided in tables and graphs. After choosing the type and the number of vehicles and determining the volume of transportation, one of the components of efficient use of vehicles is to optimize the transportation. Optimization of transportation is considered and provided in the form of mathematical formulas. Everything is presented as an example for one of the types of transportation. The issue studied and presented in this article is topical for the farms of the Mari El Republic in conditions of the market economy. That is why the data and calculations received are of practical application in the organization of cargo transportation in the agro-industrial complex enterprises and their optimization for maximum efficiency.
