The last stage of preparation of fodder mixtures is mixing of components with the help of special devices - mixers of continuous or periodic action. From the point of view of zootechnics, it is important not only to include in the fodder mixture the components provided for by the diet in the required ratio, but also to ensure an even distribution of all components throughout the volume of the mixture. The homogeneity of the mixture ensures the same nutritional value of the feed in all parts of its volume.
Currently, when creating a new generation of mixers for dry fodder mixtures, preference is given to rotating mixers. The advantages of mixers of this type compared to stationary intermittent mixers of any type are: a reduction in feed unloading time, a fully automated chamber cleaning cycle, the absence of stagnant zones and rubbing parts.
The purpose of the research is to determine the rational structural and technological parameters of the intermittent rotary mixer and to study the change in the homogeneity of the mixture when varying their values. Research was conducted in two stages: numerical modeling and experimental research.
Numerical simulation was implemented in the Simcenter Star-CCM+ software package. As research factors, we accept the following parameters: angle of inclination of the blade α (0 °, 45 °, 90 °), mass of material m (0.1 kg, 0.2 kg, 0.3 kg), rotation frequency n (30 rpm min, 60 rpm, 90 rpm), mixing duration t (1 min, 3 min, 5 min).
Experimental studies were carried out on a laboratory installation of a periodic rotary mixer.
As a result of numerical modeling and experimental studies of the mixing process in a rotary mixer of batch feed, the dependences of the change in the homogeneity coefficient of the mixture in the mixer h on the angle of inclination of the blade α, the mass of the material m, the rotation frequency n, and the duration of mixing t were established. By fulfilling the condition of maximizing the homogeneity of the mixture in the Wolfram Cloud software package, the rational parameters of the rotary compound feed mixer of periodic action were obtained: α = 50.5 °, t = 4.415 min., m = 0.11 kg, n = 43.9 rpm. At the same time, the homogeneity coefficient is h = 0.98.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
