PRODUCTION TECHNOLOGIES OF FORMED PREMIXES

Abstract

The article presents theoretical analysis and practical experience of the production of premixes (P) by different technologies of preparation of the filler. Their advantages and disadvantages are stated. The classification of premix fillers is presented and the distribution of biologically active substances in the premix composition, which is made on different fillers, is schematically presented. The technology of production of a complex filler premixes (CFP) in the form is theoretically and practically substantiated. Various methods of forming depending on the composition of the complex filler are considered, as well as the technological scheme of their production is presented. The results of industrial approbation of technologies of forming (granulation, briquetting, rolling, extrusion) of fillers and ready premixes in the production conditions of TG "VBA" "Izvestnyaki" are presented. The physical indicators of the formed complex fillers / premixes were investigated, and on the basis of the analysis of the obtaineddata it was found that granulation and briquetting can be subjected to CFP consisting of 75… 50% wheat bran and 25… 50% limestone flour. The pellet is a CFP consisting of 85% wheat bran and 15% limestone flour. Optimal technological modes of forming KNP and P in different ways have been established, as a result of which it is possible to obtain particles of P, which, upon further mixing with the feed components, ensure a high homogeneity of the finished feed. The results of the study of microbiological parameters are presented, it is established that the formation of CFP or P reduces the bacterial flora and improves the conditions during their storage. The proposed technological methods of preparation of CFP can eliminate the stratification and stabilize its composition during transportation and storage.
