Vibrating separation on sieves is one of the most common ways of loose materialsseparating, and seeds of agricultural crops in particular. Vibrating separators have a number of advantages, as they allow combining the processes of transportation and material separation. In the designs of the existing seed cleaning machines of this type, from the point of view of the design parameters of the working body, setting and mode of operation, it is difficult to improve the indicator of the completeness of the separation of grain mixtures into fractions. Therefore, there is a need to find ways to intensify this process, to develop and study the operation of technical means for their implementation.
One of the ways to improve the conditions for the movement of components of grain mixtures through the holes of the sieves is to create an electric field above them. Theoretically, there is a certain initial value of the intensity of the electric field, at which the seed will start to orient itself in it. The optimal tension value will be the one at which the degree of orientation of the seeds on the oscillating sieve in the longitudinal direction will be maximum (when their longitudinal axis will be perpendicular to the sieve).
The paper describes the results of the process study of separating seeds of cereal crops on a vibrating electric separator and substantiates the optimal values of the electric field intensity E, which can achieve the maximum effect of seed orientation on the sieve.
The results of experimental studies showed that the effect of the electric field on the seeds of different crops is not the same. It reveals itself the least on wheat seeds, since the quantity of seeds oriented in the electric field was about 35%. For barley seeds, the value of the studied indicator was 48%. The maximum percentage of oriented oat seeds was about 53% at the maximum intensity of the electric field of 6.67 kV/cmover the sieve.
It was revealed that the orientation of the seeds on the sieve affects the intensity of its sieving through the holes. Under conditions of maximum orientation, the index of sifting of wheat seed increased by 20...23%, barley seed - by 26...30%, oats seed - by 47%.

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.
