The article presents the design and energy principles for developing an infrared (IR) micronizer intended for the thermal treatment of legume grains aimed at inactivating antinutritional compounds and improving feed nutritional quality. The use of medium-wave infrared radiation (λ = 2-4 μm) was found to provide uniform volumetric heating of the grain layer and reduce specific energy consumption by 30-40 % compared to conventional convective drying. A schematic design of the proposed micronizer includes a treatment chamber with polished reflectors, a block of quartz emitters, a mixing mechanism, a multilayer thermal insulation casing, and an automated temperature-control system. The optimal design and operating parameters were determined as follows: emitter power 1.0-1.5 kW, heat-flux density 15-25 kW/m2, distance from emitters to the grain layer 150 mm, and grain-layer thickness 15-20 mm. Experimental results demonstrated that heating at 140-160 °C for 70-90 s reduces urease activity by a factor of 8-10 while preserving 97-98 % of the crude protein content. The overall thermal efficiency of the unit reached 0.78-0.82, confirming its high energy performance. The use of polished aluminum reflectors decreased heat losses by 15-18 %, and PID-based power control maintained temperature stability within ±2 °C. The developed structural and energy solutions form a scientific and practical basis for creating next-generation industrial IR systems for feed processing, ensuring the safety, quality, and nutritional integrity of legume raw materials used in compound feed production.

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.
