Abstract

Effective means of reducing the loss of grain products are its processing and bringing it to the condition humidity by means of heat treatment. One of these methods - micronization of grain allows to reduce non-productive energy consumption, improve the quality of the finished product, it can be considered the most promising for thermal processing of grain in the food industry. The purpose of this study is to increase the energy and quality efficiency of the grain micronization process by studying the features of its flow in various technological conditions. The analysis of sources devoted to the issue of grain micronization shows that the main direction of research is the substantiation of process parameters and the development of new technological methods. To successfully conduct research in this direction, it is necessary to understand all the features of the elements of this system (installation and grain) that arise during the implementation of the micronization process. The nature of the interaction between the material and IR radiation largely depends on the optical characteristics of the grain. Optical properties of materials are usually characterized by their transmission, absorption and reflection capacity. The optical characteristics of materials depend on a number of factors, such as structure, humidity, process temperature, etc. The properties of vitreous and floury grains are particularly different. The effect of grain structure especially affects the reflection coefficients of radiant energy. So, for the same wavelength of 0,9-1,3 μm and moisture content of 5-30%, for floury wheat grains it is equal to 0.68-0,73, while for vitreous grains it has a value of 0,48-0,54. There cannot be a universal approach to determine the rational parameters of the grain micronization process. In each case, there must be specific approaches to determine the rational parameters of the process. This will significantly increase the energy and quality efficiency of the grain processing process.
