  • Publication number: 20070110860
    Abstract: This invention is a modular, adjustable, easy to maintain, portable or fixed food sanitation tunnel, comprising an enclosing means for subjecting food to sanitizers including UV light, ozone, hydroperoxides, superoxides and hydroxyl radicals, and a method for using the system. The enclosing means includes one or more UV radiation sources and one or more target rods located within a tunnel, such as a c-shaped shell. The UV radiation sources are preferably UV light sources that emit UV light of approximately 185 to 254 nm. The target rods are approximately up to 0-30% titanium dioxide, up to 0-30% silver and up to 0-30% copper, by weight. The system may include a mister for the efficient production of hydroxyl radicals by the UV light sources. Parts of the system are easily removable for cleaning and for maintenance. Also, in an alternative embodiment, the tunnel is located on a frame, and the frame is on wheels.
