    THE DEVELOPMENT ADVANCED GRANULATION TECHNOLOGY OF COMPOUND FEEDS
    (2019) B. Yegorov, N. Batievskaya
    The advantages of using granular mixed fodders in comparison whith the loose сompound feeds have been analyzed in the article. A detailed analysis of the production of granulated feed in the world and in Ukraine for the last ten years has been presented. The article is dedicated to the justification of the use of granulation technology in the feed industry. The advantages and disadvantages of granulation technology are presented, as well as the structural scheme of the traditional technology of production of granulated mixed fodders with the receipt of granules grains is considered. The detailed analysis of technological processes of the traditional technology ofgranulated mixed fodders production with the receipt of granule grains with the description of technological regimes of each process has been given. The main disadvantages of traditional technology of granulated feed production have been considered and possible solutions of these problems are presented. As the development of the feed industry is characterized by the intensification of technological processes aimed primarily at improving sanitary quality, the methods of preliminary wet-heat preparation of mixed fodder, in particular, the application of expansion to the granulation process, have been presented as the basis for further development of the advanced granulation technology. The advantages of using expansion, the principle of the expander and the technological features of the process have been considered. The generalization of the conducted analytical and experimental studies allowed to develop the advanced technology of granulation in the form of a blend granulated crumb, which will increase the output of finished products. The technology for the production of granulated сompound feed in the form of a blend granulated crumb and expanded crumb have been presented in the article. The description of technological processes and technological regimes (moisture of products, use of sieves, vapor pressure, steam consumption, duration, etc.) have been presented too. The physical and microbiological characteristics of granulated and expanded feed, as well as granulated grains and expanded grains are given.
