The article presents an overview of the main methods of high-temperature processing of grain crops, which allows to improve digestibility, taste, and increase the nutritional value of raw materials with the right technology: microwave heating, IR heating, ohmic heating, high pressure and steam exposure. As raw materials for high-temperature processing, cereals, including perennial ear crops, are considered: perennial winter wheat (Trititrigia) variety “Pamyati Lyubimovoy» and Wheatgrass gray variety "Sova".

In agriculture, according to the data of the statistical collection, the production of grain crops occupies a large part. At the moment, much attention is paid to the study of perennial crops: Gray Wheatgrass (Latin Thinopyrum intermedium), Trititrigia (Latin Trititrigia cziczinii Tsvelev). These crops help slow soil erosion and minimize nutrient leaching. The non-cereal part of cultivated plants is an important reserve for strengthening the fodder base of animal husbandry and expands the range of sources of raw materials for the microbiological industry in the production of fodder proteins. The article provides an overview of technologies and equipment for harvesting grain crops, with the help of which one of the optimal methods of harvesting perennial grain crops, the stripping method, can be distinguished. This method reduces grain trauma and allows harvesting crops in the early stages of ripeness, when the grain contains more nutrients than fully ripe, and the grain has a strong bond with the stem.
