The article presents the results of a review study of modern approaches to feed material mixing and structural and technological solutions for mixing equipment used in compound feed production. The importance of high-quality mixing of complete feed, premixes, and protein-mineral-vitamin supplements for ensuring stable nutritional value, safety, and efficiency of animal feeding is substantiated. The main mechanisms of bulk material mixing-convective, diffusive, and shear mixing-as well as the features of their interaction at different stages of the technological process are analyzed. It has been established that, alongside the positive effect of these mechanisms on mixture uniformity, the possibility of segregation, remixing-induced re-segregation, and local accumulation of individual components should be taken into account. The main groups of mixture uniformity indices are considered, including variance-based indices, contact indices, and distance-based indices. The feasibility of using relative standard deviation as a practical criterion for assessing the uniformity of compound feed component distribution is demonstrated. The main designs of feed material mixers are analyzed, and their advantages and disadvantages are identified with regard to material movement patterns, energy consumption, mixing intensity, and susceptibility of components to segregation. The prospects of using Y- and V-shaped mixers in batch production of compound feed and premixes are substantiated. A structural and technological design of a Y-shaped bulk material mixer with a stepper-motor drive, gate servomotors, a damping system, an accelerometer, a rhombus-shaped distributor, and an automated control system is proposed. The application of these technical solutions creates the prerequisites for improving mixture uniformity, reducing mixing time, expanding the range of controllable operating modes, and decreasing energy consumption. The review results can be used for further substantiation of the structural parameters and operating modes of mixing equipment.

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.
