VARIATION OF GRANULOMETRIC COMPOSITION OF DIETARY FIBERS BY MILLING THEM IN A VERTICAL MILL

Abstract

In this work, we analyzed the multiple literary sources and summarized the material regarding beet dietary fibers. Their composition, physicochemical, physicomechanical and hygrothermal properties were studied. The study of the particle-size distribution showed that the content of the insoluble fraction exceeded the content of the soluble fractions in all the samples. The use of the secondary products of processing of the plant raw material is also critical; they allow improving the preventive properties of products and enriching them with dietary fibers, protein, and mineral elements. The properties and quality of the raw material are, to the large extent, determined by and depend upon its granulometric composition, that is, upon the size of particles that compose this object. The authors determined the granulometric composition of the studied nutritional supplements. It was found out that the use of the combination of the impacts together with the abrading impact led to the intensification of the process, a decrease in the milling time and the uniformity of the obtained granulometric composition. The choice of the vertical mill as milling equipment in combination with the metal balls added to it to increase the efficiency of milling and uniformity of the granulometric composition of beetroot fibers was proved experimentally.
