Annotation

The paper analyzes the current state and prospects of further development of the technology of post-harvest treatment of grain seeds and vegetables, in particular its drying, on the conditions of which depends the quality of the sowing material. One of the ways to solve this problem is to apply convective drying in a pseudo-liquefied state with periodic heating and cooling of the seeds, which allows to maintain the temperature of the dried seeds within the specified limits and thereby maintain its high sowing qualities. To study the parameters of such drying at the Vinnitsa National Agricultural University a laboratory sample of a vibrating dryer with a U-shaped working chamber for drying granular or fine-grained products was created, which allows the temperature and flow of the fluid to be controlled during drying, as well as the oscillation amplitude of the drying chamber. As a result of studies of vibration parameters influence of the working chamber of the dryer (the trajectory of its oscillations, vibration speed and vibration acceleration), the temperature and flow rate of the coolant (atmospheric air) and its humidity, the possibility of a significant reduction of energy consumption, increase of intensity and reduction of drying time is established. As a result of the research, the design and development of a vibrating convective dryer of intermittent heating with a vertical drive shaft was proposed, which allows to combine the advantages of convection vibrating tray and mine dryers, in which, in order to intensify the drying process and reduce the energy consumption, the phenomenon of thermodiffusion, or the movement of moisture in a material under the action of a temperature gradient (which coincides in direction with the flow of heat), that greatly reduces the energy consumption and duration of the drying process. Consistent alternation of periods of heating of particles of granular products with heated air and their cooling with atmospheric air, due to the phenomenon of thermodiffusion, significantly intensifies the drying process and reduces its energy intensity and leads to an increase in the productivity of the vibration dryer.

Keywords: vibration convective mine dryer, pseudo-liquefied state, thermodiffusion.

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.
