UV LED Disinfection for Food Safety

Pathogen reduction for food and beverage processing

UV LED technology offers significant process improvements and new capabilities in many food and beverage processing applications. The image above illustrates disinfection of the belt using UV LED technology to inactivate pathogens after the food has passed through the conveyor.The intense UV output has already proven itself in certain industries with reduced maintenance, consistent reliable results, and perhaps most importantly increased manufacturing speeds. UV LED technology improves dramatically year over year, and as a result it is finding its way into broader applications from online chemical stream monitoring to photochemistry to disinfection.

Phoseon research has proven wavelength selection is essential to getting the most from UV LED disinfection systems. We have discovered utilizing both 275nm and 365nm wavelengths provides a synergistic effect allowing even faster, stable reactions. Both nucleotides and proteins can be modified using this light combination. Therefore, both microorganisms and biological material can be inactivated with the right dose from Phoseon SLM-based systems. Our systems are well-suited to disinfect sensitive surfaces due to their low heat emission, high intensity, precise control, and long operating life leading to consumer safety for food processing.
