Sevostianov Ivan – Doctor of Technical Sciences, Full Professor, Head of the Department of “Technological Processes and Equipment of Processing and Food Productions” of Vinnytsia National Agrarian University (3 Sonyachna St, Vinnytsia, 21008, Ukraine, e-mail: ivansev70@gmail.com).


A task of increase of efficiency of dehydration processes of damp dispersive materials is actual for several branches of food and processing productions. In particular to these processes belongs a processing of damp dispersive wastes (alcoholic bard, beer pellets, beet press, coffee and barley slime). In case of decrease of their humidity to 20 – 25% solid phase of the waste can be used as a valuable additive to agricultural fodders or as a high-calorie fuel. This allows to resolve problems of waste utilization and environment protection. Results of previously conducting experiments and calculations demonstrate high efficiency of a method vibro-blowing loading in a closed press-form for dehydration of food industry wastes (alcoholic bard, beer pellets and coffee slime), that provides productivity of removal of liquid phase up to 20 ÷ 25 t / h, specific power consuming 2,7 ÷ 3,2 kW / t and final humidity of wastes 20 ÷ 25%. An aim of the article is to analyze known approaches to study of processing of dispersive materials (pressing, vibration and vibro-blowing loading), to examine a mechanism of fulfilment and efficiency of the process of vibro-blowing dehydration of damp dispersive materials in a closed press-form and to determine dependencies between designated efficiency parameters, working parameters of the dehydration process and physical-mechanical characteristics of processed material. Such analysis should carry out from positions of the mechanics, hydraulics and rheology of damp dispersive materials, separately for their solid and liquid phases and also for different stages of vibro-blowing loading. Elaborated calculating method will allow to create high effective equipment for vibro-blowing dehydration of damp dispersive materials with consideration of necessary characteristics of the working process and the processed material.

Keywords: dehydration, closed press-form, damp dispersive materials, amplitude, frequency, pressure, dynamic and mathematic models.

History of journal:

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  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS 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.
