Justification of Technology for Obtaining Dry Feed Concentrate for Farm Animals

Abstract

<jats:p>The results of research on the justification of technology for obtaining feed concentrate for farm animals are presented. It was found that the use of subsurface whey in the process of obtaining feed molasses contributes to an increase in its sugar content in comparison with molasses obtained from acidified water according to the currently used technology, but increases the duration of the process and the cost of electricity. It has lower humidity due to the presence of dry matter in the serum. The duration of the process of obtaining molasses based on water is less due to the fact that the availability of the reaction mixture is higher than when obtaining molasses based on serum. Molasses with a high sugar content was used to produce the concentrate. It was mixed with bran in certain proportions: 1,5:1,0; 2,0:1,0; 2,5:1,0, which corresponds to the humidity of 40, 50, 60 %. Composite variants were dried at IR-radiation flux densities of 15, 17.5, 20 kW/m<jats:sup>2</jats:sup>. The dependence of the sugar content in the composite on its humidity and the density of the IR-radiation flux is established. Indicators of the feed value of the received product are determined. A flowchart for obtaining feed concentrate has been developed.</jats:p>
