The paper presents the results of mathematical and simulation modeling of heat and mass transfer during infrared (IR) micronization of soybean grain. A physico-mathematical model was developed that accounts for the absorption of radiant energy in the surface layer, non-stationary heat conduction within the grain mass, and temperature-dependent moisture diffusion. The process was described using a system of differential equations in spherical coordinates that characterize the temporal and spatial distribution of temperature and moisture. Boundary conditions were formulated based on the energy balance at the grain surface, including absorbed infrared flux, convective heat exchange, and evaporation losses. Numerical implementation was carried out using the implicit finite-difference method in the Python environment with NumPy and SciPy libraries. A simulation model was created that enables variation of structural and operating parameters (heat-flux density, irradiation duration, grain-layer thickness) and prediction of process outcomes.
The results include calculated distributions of temperature and moisture in the grain under various processing conditions. It was established that at a heat-flux density of 20–25 kW/m², the central grain temperature reaches 150 ± 5 °C within 80–90 s, ensuring effective inactivation of antinutritional compounds without protein degradation. The average relative deviation between simulated and experimental data did not exceed 6 %, confirming the reliability of the proposed model. The simulation tool provides visualization of thermal and moisture fields and enables determination of optimal operating parameters with regard to energy efficiency and product quality. The developed model can be applied for the design of infrared processing equipment, optimization of operating regimes, and creation of automated control systems for high-protein raw materials.

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.
