The post-harvest processing of grain, especially drying, is one of the most important in the technology of agricultural production. This treatment contributes to obtaining high quality products, their long and effective preservation until the next harvest.
To obtain grain raw materials of conditioned humidity and reduce energy consumption in agricultural production, various methods of intensifying drying are used: vibration drying, recirculation drying, preheating, vacuum drying, drying using infrared radiation, drying by high frequency currents, drying grain under. the influence of an electric field, etc. The use of vibration dryers in combination with ozonation technology, which plays the role of an additional factor in intensifying the drying process, is promising from the point of view of energy consumption and the quality of the obtained raw materials.
Ozone inhibits seed respiration, which in turn contributes to the preservation of a larger supply of nutrients before sowing compared to untreated material. Accelerating the decomposition of complex proteins and starch into constituent elements, ozone, being a strong oxidizing agent, simultaneously acts as an effective disinfectant that destroys the infection of Fusarios and smut fungi.
The prospect of using vibration drying and ozonation technology contributes to the creation of electronic devices for the synthesis of ozone with increased productivity - tubular ozonizers, which is ensured by increasing the inhomogeneity of the electric field strength between the electrode on the outside of the dielectric element and the electrode on the inside of the dielectric element.
The paper presents the results of a theoretical study of energy-physical and thermodynamic processes that occur in the developed electronic device for the synthesis of ozone in order to substantiate and optimize its operation in the future and to ensure energy-efficient drying of grain raw materials during post-harvest processing.
