Vibro-pressing loading is one from most effective methods of dehydration of damp dispersive materials such as alcoholic bard, beer pellets, beet press, coffee and barley slime for their further use as valuable additives to agricultural fodders or as a fuel. Main efficiency characteristics of the equipment for dehydration by the method of vibro-pressing loading are: productivity of liquid removal up to 20 ÷ 25 t / h, energy efficiency 2,7 ÷ 3,2 kW / t, final humidity of processed material 20 ÷ 25%. High efficiency of the method conditioned by periodical overdistribution of solid particles of processed material in a press-form of the equipment with their mutual rotations, sliding and movements in locations of more stable balance, with more dense stacking of particles and removal of liquid from spaces between them. There are several types of drives for vibro-pressing equipment: mechanical (unbalanced), hydraulic and electromagnetic. Each this type of drives has some advantages and disadvantages. One of tasks of this article is to analyze these types of drive and to select an optimal variant that will provide maximal productivity of working process, minimal energy expenses and humidity of processed material. A scheme of a versatile vibro-press that can be equipped with unbalanced, hydraulic pulse or electromagnetic drive is presented in the article. There is elaborated dynamic and mathematic models of the vibro-press. Equations of the mathematic model set connection between of working parameters of dehydration process, design parameters of the equipment and physical-mechanical characteristics of processed material. These equations can be used as a foundation for elaboration of a design calculation method for determination of optimal parameters of the vibro-press depending from given characteristics of material and parameters of dehydration efficiency.

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"
