DIGITAL EXPRESS ANALYSIS OF BUCKWHEAT GRAIN FRACTIONAL COMPOSITION AS A STAGE OF INDUSTRY 4.0 INTRODUCTION AT GRAIN PROCESSING ENTERPRISES

SFODRL

Abstract

The modern level of digitalization in the grain storage and processing industry is represented by neural network methods (separation of grain mass and impurities by color), computer vision algorithms (determination of grain vitreousness), methods of grain separation by optical prope­rties (photosorting using high-speed scanning of grain mass and subsequent image processing according to a given algorithm – color characteristics, shape, geometric dimensions). Buckwheat grain is characterized by a large variability in size, which requires its separation into fractions by size before being sent for peeling, therefore, an important aspect of increasing the efficiency of buckwheat fractionation is the possibility of digitalizing the definitions of grain granulometric composition. The objects of research in the work were samples of buckwheat grain from 6 districts of the Altai Territory. The analysis of the fractional composition of buckwheat samples was carried out according to the "Rules of organization and management of the technological process at grain enterprises" in the program "Granulometry" and "Histograms" developed at the Department "Technology of grain storage and Processing" AltSTU. This method of determining the granulometric composition of buckwheat grain, allows you to obtain a quantitative assessment of particle sizes, use information technology in production, thereby reducing the complexity of analysis, besides digital systems have an exceptional ability to promptly correct the results and correct errors. Comparison of the results of buckwheat grain fractionation by the sieve method and using the "Granulometry" program showed high convergence of the data obtained. The average processing time of one sample by the proposed method is reduced by 3-4 times. The results of the study confirm the effectiveness of the "Granulometry" program for express analysis of the fractional composition of buckwheat grain, selection of sieves and preparation of batches of buckwheat for processing.
