Andrii Puhach – Doctor of Science in Public Administration, Professor Department of Agricultural Machinery Dnipro State Agrarian and Economic University (Sergiy Yefremov str., 25, Dnipro, Ukraine, 49600, е-mail: anpugach13@gmail.com).
Ruslan Brovko – graduate student of the Department of Agricultural Machinery Dnipro State Agrarian and Economic University (Sergiy Yefremov str., 25, Dnipro, Ukraine, 49600, е-mail: ruslan.brovko@ukr.net).
The object of the study is a Krupp EP20 screw press in a modified design with a feeding device, namely a technical system that includes horizontal and vertical screws and a screw path in the part of feeding and pressing oil-containing raw materials. An analysis of scientific and technical information was conducted on the issue of designing and operating oil pressing equipment, as well as the issues of ensuring its reliability, durability, and efficiency. Structural modifications of the Krupp EP20 screw oil press were made to provide the material (oil raw material) with uniformity before feeding into the screw path with a complete and structured list of advantages that confirm the feasibility of using the proposed solution, which allows a comprehensive assessment of the effectiveness of the work performed: no material hanging between the horizontal feeder and the screw path; elimination of cavities in the material flow; uniform material density; prevention of material sticking on the feed coil; stable operation and productivity of the press. The developed design of the screw oil press was tested and its productivity for processing oil-containing raw materials from 680 t/day to 720 t/day of sunflower seed raw materials was established. After testing the pressing, the following products were obtained: - unrefined, unfrozen, pressed sunflower oil of the highest and first grades; - sunflower cake - a solid product obtained by pressing. To establish the qualitative characteristics of the oil, the physical and chemical properties of the oil were determined. The test samples of the obtained sunflower oil fully met the established quality indicators in accordance with the requirements of DSTU 4492:2005 "Sunflower oil. Technical conditions". Thus, it can be stated that the obtained unrefined oil is characterized by proper quality indicators and meets the current standards established for edible oils. The developed press can meet the needs of both small and large processing enterprises that grow oilseeds.

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.
