On the Issue of Energy Efficiency of Dividing Grain Materials into Parts

Cereals have become widely used as affordable food products, and their processing unlocks their nutritional potential. A decrease in the energy efficiency of technological processes for processing grain raw materials occurs due to changes in the design of specialized machines and the use of less energy-intensive grinding methods, for example, by shearing. Grain feed entering the body is transformed in the digestive tract and ensures the implementation of all vital functions of the animal. The fewer nutrients are excreted, the more efficiently the feed is used. The article presents a scientific hypothesis that the energy efficiency of the grain processing process should consist not only of the specific energy intensity of the process (the ratio of energy consumed to productivity), but also equally of the feed bioconversion indicator. Tests on dividing caryopsis into parts were carried out on privately manufactured equipment using strain gauges. An experiment to determine the nutritional value of wheat grain raw materials was ordered from a specialized laboratory. An analysis of the known accumulated experience and available literature shows that when processing grain raw materials, on average, the leaders in energy costs are: grinding, drying, separation and mixing. The proposed methodological approach includes the development of an objective description of the process of processing grain crops using the example of preparing feed mixtures for farm animals.
