The successful development of the livestock industry directly depends on veterinary and sanitary wellbeing. There are different types of disinfectants on the market, but their use in the same doses or overuse rates leads to increasing antimicrobial resistance of microorganisms. This fact can cause the appearance of more robust microorganisms, increase economic costs, and lead to an environmental disaster in the livestock sector. The disinfection efficiency depends on many factors, such as the concentration and temperature of the disinfectant, exposure time, room air temperature, the purity of the treated surface, and the sprayers' technical capabilities. A laboratory setup has been developed to simulate the disinfection process using a new sprayer under various operating conditions. A measuring unit was developed to conduct studies of the dispersion analysis of the spray. According to the experimental data, graphical dependencies are constructed showing the effect of the working pressure in the vortex device on heating of compressed air at the inlet to the sprayer, the degree of heating of the disinfectant liquid by compressed hot air, and the kinematic viscosity of the disinfectant liquid versus its temperature. The droplet sizes at different conditions of the sprayer operation are obtained. A thermomechanical (dispersion-condensation) method of applying the disinfectant liquid is proposed to increase veterinary and sanitary measure efficiency. The method's principle is based on breaking up the liquid into fine particles and heating them from a hot gas flow kinetic energy. Based on the obtained experimental data, the operating conditions of the developed vortex injector sprayer were determined to satisfy specific veterinary and sanitary requirements.
