This study looks at determining the main trends in the application of microwaves on plants in agricultural production in the processing of grain material, it provides examples of their effectiveness and an overview of the use of microwaves on plants available on the Russian market. Additionally, the research studied the experience and developments of leading scientists in the field of microwave radiation. Analysis of the available sources provided information on the positive effect of microwave radiation in the processing of crops. The use of microwaves on plants during drying destroys pathogens and bacteria, in particular, microwave processing of red lentils reduces grey mould damage by up to 30%. Positive results are also noted in the microwave processing of other crops, providing an increase in germination capacity of up to 7% and yield growth of up to 6%. The microwave plant market in Russia is represented mainly by dryers, and the use of microwaves on plants combining several functions of drying, disinfection, and pre-sowing stimulation.

Currently in Russia and other countries in family farms there is a demand for lowering cost of animal production. Main direction to achieve new terchnological solutions characterized by low energy constumption and high efficiency with maintaining high quality of product (mineral). For example, lately in animal production are acquired concentrates with low unity costs. Realising targets releated with lowering costs of forage production with usage comminution and crease of grain. Previously conducted own researches and literature analises shows, that currently used solutions are characterized by big errors made by construction of the devices, and technology effect of obtained product (grain). The paper presents the criteria for optimalization of technical indicators of shredding devices affecting the quality of the product.
