This study addresses the need to utilize bench-scale experimental results for ultraviolet (UV) light disinfection on solid food surfaces by proposing a novel framework to evaluate the fluence rate field of arbitrarily placed UV sources to ensure proper disinfection in industrial-scale food processing. Despite extensive research establishing UV fluence values for disinfection of various food types, industrial applications often face challenges due to nonhomogeneous UV distribution. This study introduces a method capable of determining the fluence distribution on solid food and food contact surfaces in both static and moving environments. Additionally, it aids in selecting the appropriate light sources and irradiation times. Our model leverages UV radiation models from different engineering disciplines to determine the UV fluence and dose distribution on the surface of convex objects. This helps to understand and optimize processes for proper decontamination, improved food quality, and a longer shelf life for processed products.
