From a botanical point of view, walnuts belong to the genus Juglans, which has more than 20 different species. The name of this genus comes from the Latin phrase "iovis glans", which translates as "Jupiter's acorn". Walnut kernels are used in many industries - in medicine, food and perfume industries. With the addition of hard fruit shells, the technological process of tanning leather is carried out. The pericarp, due to its high iodine content, is used to dye fabrics in various shades of brown, as well as for medical purposes. Walnut shells are used to make activated carbon, grinding stones, linoleum, etc. Currently, Ukraine occupies the sixth-eighth position in the world ranking in terms of walnut cultivation, production and export. Over the past 30 years, an average of almost 90,000 tons of nuts have been produced per year. China is the world's leading producer and exporter of walnuts in shell, with over 705,000 tons per year. The top three countries are the United States and Iran, with over 405,000 tons and 256,000 tons respectively. Turkey, Burkina Faso and Mexico are also among the world's leading producers of walnuts. Almost 60% of walnuts in shell are grown and produced in Asia, 25.5% in South and North America. Europe produces 14.4%, Africa 3% [1-3].
Based on the results of previous studies, which established the prospects for using vibration effects on the processed medium during drying, as well as ozone during dehumidification of various agricultural raw materials, we developed the idea of combining vibration technologies and ozonation, which we implemented in a vibration dryer for processing walnuts with an ozone-air mixture.

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.
