Krystyna Lupko – Ph.D. student of Dnipro State Agrarian and Economic University (St. S. Efremova, 25, Dnipro, Ukraine, 49000, e-mail: kristina.dsau@gmail.com, https://orcid.org/0000-0001-9237-5659).
Separation is an important process of processing seed material of small-seeded crops. This process is based on technical and technological principles of separation of seed material depending on differences in physical and mechanical properties of individual components of seed material. The quality of seed directly depends on the quality of separation. Cylindrical triers are seed cleaning machines designed to separate seeds that differ in length. The working body of the trier is a cylinder with an inner honeycomb surface and a prefabricated hopper, which is mounted on the axial support of the cylinder. The principle of operation of the trier is based on the rotation of the cylinder, during which the cells get seeds of different geometric sizes. The aim of the study is to determine the theoretical patterns of change of technological parameters of the process of separation of seed material of small-seeded crops from the design and regime parameters of the cylindrical honeycomb trier by numerical simulation. A model of the process of separation of seeds of small-seeded crops on a cylindrical honeycomb trier in the Simcenter STAR-CCM+ software package has been developed. Based on the physical and mechanical properties of seed material on the example of mustard seeds, the initial and boundary conditions of the cylindrical honeycomb trier, the separation process is visualized depending on research factors (number of seeds and impurities in the seed mixture, trier cylinder and trier cylinder and diameter). The next stage of research is to determine the dependence of the values of the minimum and maximum angles of seed exit from the cell of the trier cylinder on the research factors.

Publisher Vinnytsia National Agrarian University
In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University is the chief editor of the "Vibrations in engineering and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
