 According to the results of the NDR, the methods and possible directions of automation of the technological process of grain drying in a tower dryer were investigated. A new structure of an automated grain drying system based on programmable logic controllers (PLCs) was proposed, and an automated system based on this was developed and put into production. The developed automated grain drying management system solves the problem of improving the quality of grain processing and reducing overhead costs when using the technological process of drying. About 50% of the grain harvested on the territory of Ukraine has high humidity and needs drying. Only after all excess moisture has been removed from the fresh grain and it has been brought to a dry state, you can count on long-term storage and further use of the product. Grain drying is a complex, continuous and energy-intensive process. Changing the technological parameters of drying (for example, temperature regimes) affects its quality parameters. In addition, at grain processing facilities, the number of executive mechanisms and parameters that are controlled is steadily increasing, and the operator is no longer able to independently manage the technological processes of loading, unloading, preliminary processing, etc. On the other hand, the reduction of energy costs for grain drying is considered as the most important task in the development of new drying technologies and designs of grain dryers. Introduction of new or modernization of existing dryers can to be considered effective enough, as a reduction in specific energy consumption has been achieved (with mandatory preservation of grain quality). In this connection, the issue of complex automation of grain processing and storage facilities arises, as drying is one of its main ways to improve grain quality, save energy, reduce the impact of the human factor, and increase enterprise productivity.
