Ozonation for food slicing machine

An apparatus for disinfecting food slicing machines during use, and which does not necessitate stopping the machine to clean. The apparatus generates ozonated water and directs the ozonated water onto the band blade of the machine. The ozonated water is highly antibacterial, but leaves little or no undesirable residue. The apparatus includes a first fluid circuit in which the water flows and is ozonated. A second fluid circuit is in fluid communication with the first circuit, and has an outlet, such as a nozzle, that directs ozonated water onto the band blade. Preferably, the outlet is connected to a blade guide through which the band blade extends, and thereby supplies ozonated water to where it is the most needed: at the cutting surface.
