Abstract

The paper presents the construction of an air-jet ultrasonic aerosol generator that allows adjustment of the dispersing jet. It shows the calculation methodology which includes an air-jet ultrasonic generator and the dosing chamber of the atomized liquid. It is considering using this type of air-jet ultrasonic aerosol generator for cleaning and antimicrobial treatment of surfaces covered with biofilm in the food industry. High antimicrobial resistance of microorganisms in biofilms in the food industry is influenced by the failure of an agent to penetrate inside the biofilm.
