Automated control scheming of flat-type granaries to ensure grain safety

The article considers the implementation of the strategic grain production planning to provide the population with high-quality and safe food in the Russian markets, as well as to improve the standard of living. Various conditions of grain storage have been investigated. The analysis of flat-type granaries has been carried out and their shortcomings have been revealed. At the established higher wheat moisture the problems that contribute to the loss of weight and quality have been identified. Methods of moisture measurement for grain crops have been studied. During the study, the grain moisture index was measured using thermogravimetric, conductometric, dielcometric and microwave moisture measurement. The influence of the wheat «Favorit» and «Donskaya Elegia» moisture mass fraction on self-heating and grain contamination has been studied. These grain varieties were stored in a flat-type granary. A promising direction for the automated control scheming is the use of waveguide grain moisture sensors for technological operations which require a flat floor surface. The sensor design features and the conditions for their placement have been presented. The study have proved the need to create an automated humidity control scheme to ensure basic indicators of wheat quality. The paper proposes a scheme of water-wave sensors installation.
