INFLUENCE OF WATER-TREATMENT PARAMETERS ON INDICATORS OF FLOUR PRODUCTION WITH THE USE OF GRAIN SPELT

Currently, the spelt grain can be characterized by growing demand due to its high economic properties. Flour is a popular product of grain processing in Ukraine. An important indicator of the competitiveness of a modern flour mill is the efficient use of raw materials. It is not fully studied the technological and flour-mill properties of grain of the spelt determine the relevance of the research, the results of which are given in the article. The purpose of the scientific research is the scientific substantiation of the optimal parameters of water-heat treatment of wheat grain during the flour production in the low-productivity factories. The research methods presented in this article refer to generally accepted and valid at the time of their conduct. Approximation of the obtained data was carried out using methods of statistical analysis and mathematic modeling. The greatest influence on the endosperm usage coefficient and the complex efficiency criterion determines the moisture content of the grain, but the duration of the irrigation has the least effect. The optimal parameters of the water-heat treatment are grain moisture 15.0-15.5% and the duration of evaporation up to 5-10 hours. Reducing the duration of wetting up to 5 hours is recommended in the low productivity enterprises, as the corresponding losses during the production of flour are offset by a reduction in the complexity of the process. A promising direction of further research is the study of the influence of parameters of the developed flour-milling process on wheat grain spelled. The results of the relevant studies will make it possible to integrate new raw materials into existing high-productivity flour mills
