Device for cleaning food with ozone water, and method of cleaning food using cleaning device
First Claim
1. A food washing apparatus for washing food materials such as food material stuffs to be eaten raw, grains, tubers, seeds, or nuts by using ozonized water, comprising:
- an ozonized water generator;
a washing tank in which the food materials are put and which can rotate to wash the food materials, the washing tank having a polygon shaped cross-section extending perpendicular to an axis of rotation of the washing tank;
a drainage part formed on only one side of the polygon shaped cross-section of the washing tank and including a large number of openings to such a degree that water passes through and the food materials do not pass through; and
wash water pipings which are disposed in the washing tank in an axial direction and in which water spray holes for spraying wash water including at least ozonized water generated by the ozonized water generator into the washing tank are formed,wherein while at least part of the wash water sprayed from the wash water pipings is drained from the washing tank every rotation of the washing tank, washing of the food materials is performed.

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. Further, there is also a method in which a receiving tank (8) for wash water drained from the washing tank (1) is provided, and at least one part of the wash water in the receiving tank (8) is returned to an inlet side of the ozonized water generator (10) to perform cyclic use of the wash water.

41. A food washing apparatus for washing food materials such as food material stuffs to be eaten raw, grains, tubers, seeds, or nuts, by using ozonized water, comprising:
-
an ozonized water generator for generating ozonized water at an anode side by electrolysis of water and for generating alkaline water at a cathode side; an ozonized water tank for storing the ozonized water generated at the anode side by the ozonized water generator; an alkaline water tank for storing the alkaline water generated at the cathode side by the ozonized water generator; a rotatable cylindrical washing tank in which a drainage part including a large number of openings to such a degree that water passes through and the food materials do not pass through is formed in a longitudinal direction; and a second wash water piping which is disposed to pass through substantially a center part of the washing tank in an axial direction and in which a large number of water spray holes are formed at a place corresponding to a rear half portion of the washing tank; a first wash water piping which is an outside pipe of a double pipe having the second wash water piping as an inside pipe and formed at a place corresponding to a front half portion of the washing tank, and includes a large number of water spray holes formed in an axial direction, the outside pipe and the inside pipe being coaxial and coextensive for a portion thereof; and a piping system capable of supplying the ozonized water, the alkaline water and clean water to each of the second wash water piping and the first wash water piping by a changeover operation of valves, wherein while at least one part of wash water sprayed from the first and the second wash water pipings is drained from the washing tank every rotation of the washing tank, washing of the food materials is performed. - View Dependent Claims (42, 43, 44)
