ANALYSIS OF HYDROTHERMAL FEATURES OF GRAIN AND INSTRUMENT DESULPHURIZATION OF MOISTURE CONTROL

The article deals with hydrothermal properties of grain and describes its behavior during moisture treatment, for optimization of technological properties of flour, cereals and mixed fodders, influence of humidity on storage and processing modes of grain and grain products. The moisture content of the grain is discussed, which exceeds the established norm, as a result of which the grain begins to rapidly spoil and the amount of useful substances in it sharply decreases. In this regard, it is recommended to control the processing processes of grain processing, which includes control and regulation of humidity at all stages, from raw material procurement to storage and shipment of finished products. In order to achieve the goal, it is proposed to study, scientific justification, and to decide on specific and little learned tasks of research in the field of measurement of technological parameters of grain. The requirements for selection of the method and design of the instrument for controlling the moisture content of the grain, as well as their high measurement accuracy, the possibility of taking measurements in a continuous technological flow, where the subject of the study should be theoretical and experimental research based on the use of high-frequency or ultra-high-frequency methods and their equipment for controlling the moisture content of the grain in technological processes, are analyzed. Recommendations are given for the development of the nomenclature of standardized metrological characteristics of measuring instruments, and justification of the method of their experimental evaluation, as well as measures aimed at ensuring uniformity of measurements and verification schemes for the developed instruments and control methods for enrichment products, as well as requirements for metrological characteristics of grain moisture control instruments.
