Storing grain quality materials in post harvest handling and storage is largely dependent on correctly implemented the drying process. In agricultural production mainly use costly convection dryer. The main share of wasteful energy consumption accounts for heat drying agent, some heat is lost to the environment through the working surface of the dryers and spent coolant. Ways to reduce these energy costs is to reduce the amount of drying agent in the process to the level necessary to absorb and remove moisture from the dryer and the working volume of the principles of targeted "delivery" of energy to vysushuyemoho material. Last principles successfully implemented using contactless energy supply of electromagnetic fields in a material exposure by microwave or infrared radiation. The article deals with the theoretical background processes of drying material in cyclic mode with infrared heating and high frequency electromagnetic field. The equations change over time settings grain material by heating using high frequency electromagnetic field or infrared light and ventilation in the grain does not allow heated air drying cycle count process. The algorithm calculating the overall process of drying cycle to determine rational modes of the process, providing minimize energy costs.

In the article of experimental research and a particularly important prerequisite is to establish the required values with the least error, because the reliability of the information obtained from the processing of experiments is key to determine the true value of a parameter. According to the results of the study, data were obtained on the actual operating time for failure of the elements of the vibrating platforms VB-10V. The research identified the main prefabricated units and parts that failed: motor, gearbox, synchronizer, vibrator, propeller shafts, clutches. At the same time, cardan shafts and couplings failed the most. In some cases, the destruction of bearings in vibrating exciters has been demonstrated. The method of determining the number of experiments and estimating the error in measuring the studied parameters is based on the basic provisions of probability theory and mathematical statistics. The results of the research indicate a low level of reliability of the cardan shaft, which leads to a long downtime at an unscheduled time of repair, which is 0.8-1.2 hours in the presence of spare parts in stock. As a result of processing the statistical information of the cardan shaft reliability indicators, it was found that the average resource is 261.95 hours, the standard deviation is 53.2 hours, the coefficient of variation is 0.27.

Theoretical calculations and experimental studies show that during the technological process of transporting seeds by technical means, in particular ladle conveyors, macro- and especially microtrauma of grains occurs, which affects a decrease in quality indicators. Analysis of the studies shows that the structural parameters of the working bodies, the biological and physico-mechanical properties of the kernels, as well as the material for the manufacture or coating of the working elements, affect the trauma and quality of the seeds. Experimental data showed that microtrauma of winter wheat grains before transportation was in the range of 22,9- 23,5%, and after completion of the transportation process was 45,3-46,4%, that is, doubled. Further studies to improve the quality of seeds of grain crops, reduce the harmful effects of microorganisms on caryopsis and reduce macro- and microtrauma should be carried out in the relationship and the complex of biological and physico-mechanical features of the entire technological process.
