Food product surface sterilization apparatus and method

This invention describes an apparatus designed to sterilize the surface of food products by exposing them to germicidal agents like ultraviolet light, sound waves, or ozone. Food moves through the apparatus, for example, by rotating in a drum or via a screw conveyor, while being treated. The system includes a controller to manage the sterilization process safely and effectively, and the claims specifically focus on germicidal emitters that can withstand high-pressure water sprays for cleaning.

Why it matters: Since 2003, advancements in UV-C LED technology offer more compact, durable, and energy-efficient germicidal emitters, making robust, high-pressure-resistant designs more feasible. Modern industrial control systems also simplify integration and safety protocols for food processing.
