  • Device for cleaning food with ozone water, and method of cleaning food using cleaning device
    Patent number: 7275551
    Abstract: A food washing apparatus of the invention includes an ozonized water generator (10), a cylindrical washing tank (1) in which the food materials are put and which can rotate to wash the food materials, a drainage part (4) formed at a part of the washing tank (1) and including openings to such a degree that water passes through and the food materials do not pass through, and wash water pipings (2, 9) which are inserted and disposed in the washing tank (1) in an axial direction and in which water spray holes (2a, 2a) for spraying wash water including at least ozonized water are formed, and while at least one part of the wash water sprayed from the wash water pipings (2, 9) is draind from the washing tank (1) every rotation of the washing tank (1), washing of the food materials is performed.
    Type: Grant

  • Electrolytic ozone water production method and device therefor and solid polymer electrolyte membrane regenerating method
    Patent number: 6787020
    Abstract: A method and apparatus for producing water containing ozone by electrolysis includes an anodic electrode, a cathode electrode, and a mechanism for advancing and reversing both or at least one of the electrodes, wherein DC voltage is applied between both electrodes in the state of a solid polymer electrolyte membrane pressed by both electrodes, water flows on both sides of the solid polymer electrolyte membrane, water containing ozone is produced at the anodic electrode, and an operation for changing a pressing force is carried out, after which, the pressing force returns to an original pressing force, thereby carrying out a recovery of the solid polymer electrolyte membrane while continuing the production of the water containing ozone.
