Designing the structure of the system for automating the process of grinding sunflower meal

Automation of agricultural production allows to increase reliability and extend the service life of technical means, etc. In the cost of livestock products, feed accounts for up to 70% of all costs, which causes its uncompetitiveness and, therefore, there is a problem of creating a highly efficient technical means for the production of feed, and especially for grinding sunflower meal for the preparation of high-protein feed. The purpose of the article is to design the structure of a system for automating the process of grinding sunflower meal for the preparation of high-protein feed by using DFD data flow diagrams. Based on the analysis of literature sources, a general view and schematic diagram of an automated control system for the grinding of sunflower meal on an upgraded SM-2500G shredder has been developed, which will allow controlling its operation when receiving cake in granular and bulk forms. A description of the DFD diagram of an automated control system for the grinding of cake on an upgraded shredder is presented. The values of the number of functional points and link connectivities are determined depending on the DFD diagrams. The prospect of further implementation of the obtained research results is the use of various types of DFDs, which will allow to design the structure of the system for automating the process of grinding sunflower meal for the preparation of high-protein feed on an upgraded SM-2500G shredder.
