STUDY OF THE PROPERTIES OF RAPESEED AS A DRYING OBJECT
Vadym Paziuk – Doctor of Technical Sciences, Associate Professor, Leading Research Fellow of the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine (2 Bulakhovsky St., Building 2, Kyiv, 03164, Ukraine, e-mail: vadim_pazuk@ukr.net, https://orcid.org/0000-0002-4955-1941).
The study of the properties of rapeseed as an object of drying involves knowledge of physico-mechanical, hygroscopic, chemical and thermophysical, characteristics. The physico-mechanical properties of seeds include: size and shape, aerodynamic properties, surface condition, specific gravity, porosity and flowability of the grain mass, packing density of the grain mass, bulk and absolute weight, color, hydraulic resistance.
The chemical and mineral composition of rapeseed was analyzed, it is rich in oil content (40-45%), proteins (25-26%), and also rich in potassium (979 mg) and phosphorus (840 mg).Hygroscopic characteristics include studies of the equilibrium humidity of rapeseed under the influence of relative humidity and air temperature. The need to dry rape to 8% reduces biochemical processes in the middle of the material, which improves the quality and does not spoil the seeds. Thermophysical characteristics increase with an increase in the temperature of the coolant and the moisture content of rapeseed. Formulas for calculating the specific heat capacity and thermal conductivity coefficient of rapeseed from the humidity of the material and the temperature of the heat carrier are given. To determine the qualitative characteristics of rapeseed, a method of determining biochemical parameters is presented. Determining biochemical indicators such as germination and germination energy of rapeseed before and after drying allows finding rational regimes. Determined factors of intensification during drying of rapeseed are as follows: increase in driving force, increase in kinetic coefficients, increase in the contact surface of the grain with the coolant. An increase in driving force due to an increase in the difference in moisture content and temperature of the coolant and grain. An increase in the kinetic coefficients is achieved due to an increase in the coefficients of heat transfer, thermal conductivity and drying. An increase in the contact surface of the grain with the coolant is possible due to the activation of the surface and the creation of a loose, pseudo-liquefied or suspended grain layer.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
