In Ukraine, as the raw material for the production of cereals, flour, flakes, the following main crops are used: wheat,barley, buckwheat, oats, corn, rice, millet, peas. The volume of world grain production has grown significantly in recentyears. In Ukraine, corn is the main fodder crop, and only a small amount is used as a food. Corn has the leading place amongthe major grain crops in world agricultural production. Corn grain production is concentrated in warm regions. In some regions,corn is the basis of the traditional nutrition of the population, but basically it forms part of the feed in the feeding offarm animals.Today about 3500 food and technological products are produced from corn. Corn can largely satisfy the needs oflivestock, its share is almost 30% of concentrated feed. With the advent of new directions in the development of biotechnologyin the world, the significance of this culture will increase even more. The programs of biofuel production are gaining momentum,in connection with which a significant expansion of the sown area under the corn is foreseen.In this article features of water-heat treatment of corn grain during preparation for processing are provided. Featuresof the use of hot and cold grain conditioning in the cereal industry are considered. In the course of this study, it wasdetermined that the optimum water temperature for humidifying corn sugar is 60 ºС. Using a certain water temperature duringhumidification will enable to perform more efficiently the directed change of technological properties of grain, to ensurethe high efficiency of its further processing. The results of research of the water absorption capacity of sugar corn grain arepresented. As can be seen from the research carried out to improve the efficiency of the STI and optimize the processing technology,the grain lots are fractionated into more homogeneous flows of physical properties and treated separately.
