Walnuts are currently a unique product, the components of which are used in the food industry, the production of medical and cosmetic products, the production of building materials, as an energy product and in other areas of activity. Ukraine is one of the leading producers of walnuts, but most of them are offered in the shell. The maximum economic efficiency of walnut processing technology is achieved through the use of a full cycle of processing and the use of all components: pericarp, kernels, shells, membranes. Therefore, the development of an energy-efficient line for a full cycle of walnut processing is currently very relevant for this promising branch of agriculture. Analysis of recent studies and publications shows that the attention of researchers and practitioners in most cases is directed to solving individual problems that arise before them, that is, individual technological processes and operations have been studied. Namely, the complete processing of sins ensures the maximum profit from their cultivation. In this work, the authors set a goal to develop a technology for processing walnuts that would provide the most complete cycle of their processing, which will provide, accordingly, the maximum profit from its implementation. The technology of complete processing of walnuts involves the use of a significant number of different machines that use different types of energy. For more efficient use of energy, it is recommended to use measures and means that intensify technological processes. In particular, an effective means of intensifying technological processes is the vibration effect on the processed material. This is especially true for the drying operation, because the implementation of this operation requires almost half of all the energy consumed in the technology. The technology also involves the use of non-traditional energy sources.

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.
