The article is dedicated to the development of innovative equipment for the inactivation of milk microflora. It provides an analysis of existing methods to suppress the growth and destruction of microorganisms in milk, aiming to enhance product quality indicators. The advantages and disadvantages of current pasteurization equipment are highlighted. An overview of alternative methods for milk inactivation is presented, focusing on the impact of ultraviolet radiation on bacteria and lower organisms. It is concluded that a major advantage of ultraviolet (UV) milk treatment, in addition to its bactericidal effect, is its minimal impact on proteins under efficient operating conditions.
Considering the limited penetration of UV rays into milk, a device is proposed—a milk disinfection separator that separates microorganisms from the main product by placing them in the form of a thin laminar film accessible for effective irradiation. Special attention is given to justifying the parameters of the UV irradiation section. The methodology for hydraulic calculation of device movement is presented, along with a method for determining the bactericidal effectiveness of UV irradiation on microorganisms and the necessary lethal dose for this purpose.
By specifying the system's productivity, knowing the bactericidal dose required to deactivate bacteria, and considering the irradiation intensity of the UV source, the dimensions of the irradiation section and the required electrical power of the equipment are determined.
The article proposes modern LED arrays with the necessary UV wavelength range, along with diagrams for their connection and equipment control.
Key words: UV irradiation section, milk inactivation, milk disinfection separator, lethal radiation dose, LEDs
