Abstract: Now much attention is paid to a problem of decrease in power consumption of production and upgrading of the received products and, as a result, leading to increase in cost efficiency [1]. By production of forages and feed additives, the extrusive technologies including are more and more actively applied: crushing, mixing and pressing. However in this technology mean the considerable raw and metabolic cost. The rational technology of processing of grain raw materials has to ensure safety of the useful properties of raw materials at each stage of its processing in particular at stages of its crushing and extruding. In a number of works there are data about use of cryogenic technologies for decrease in power communications in the processed raw materials (preliminary partial destruction of the processed raw materials due to the expansion which is present at it the free moisture upon its transition from liquid state to solid). In particular A.I. Naumov, Egorov G. And, E.D. Kazakov, V.L. Kretovich investigated as temperature influences and also in unison temperature and humidity, and mechanical characteristics of wheat of a grade Tsezium 31 of Altai Krai. Mealy and vitreous fractions of grain were exposed the negative and positive temperatures, and then to a refinement. It was established that low temperatures affect not only covers, but also all volume of grain. If temperature of grain is negative (lower than-10 and below), then the free and bound moisture which always is in a time, capillaries and intercellular spaces of grain, turning into ice and extending, loosens structure of grain and weakens communications between its constituents. As a result of it the resilience of grain to a refinement decreases. Besides, decrease in temperature leads to decrease of a kinetic energy of a headway of molecules of substance, reduces their speed and a free length, grain becomes less viscid and ductile, its brittleness increases.

Key words: crushing, power consumption, grain raw materials, technological process, power, formula-feed industry, mathematical model, resource-saving.
