On the anode side of the electrode 21, the oxidizing agents such as oxygen and chlorine contained in the cleaning liquid 15 react and are removed from the cleaning liquid 15, so that the redox potential of the cleaning liquid 15 shifts to the negative side. When 2000 CC tap water was actually applied for reduction treatment by applying a DC voltage of 15 V between the electrodes plated with platinum on titanium metal, the redox potential before treatment was about +530 mV, while 1 hour Was reduced to about -200 mV. The redox potential was measured using a glass electrode type hydrogen ion concentration meter manufactured by Horiba Ltd. When the redox potential becomes low, the viscosity of the cleaning liquid 15 becomes low and the permeability to food becomes high.
It is considered that this is because the surface tension of the is low. Therefore, the cleaning liquid 15 permeates into the concave portion of the food surface, and the pollutants such as pesticides attached to the cleaning liquid 15 can be eluted or can be easily released, and the cleaning performance superior to that of ordinary tap water can be obtained. Obtainable. It should be noted that the electrode 21 used for the reduction treatment of the cleaning liquid 15 is preferably made of the above-mentioned titanium metal that is chemically stable and is plated with platinum. It may be composed of a harmless material even if eluted. Further, the reduction treatment of the cleaning liquid 15 by the potential control means 20 is not a consumable material,
Since electric energy is used, stable processing capacity can always be achieved in long-term use.

Since it is in a floating state, part of the food surface is always exposed, and it is difficult to remove contaminants adhering to the exposed part. In this embodiment, the cleaning liquid 15 is sprayed from the sprayer 35 to the exposed portion of the food, so that the contaminants can be mechanically removed by the physical energy sprayed from the sprayer 35. On the other hand, in the portion immersed in the cleaning liquid 15, the cleaning liquid 15 is the potential control means 20.
Since the liquid reforming means 27 imparts surface activity to the surface of the cleaning liquid 15, the cleaning liquid 15 permeates the food to promote the elution of contaminants, and the spraying pressure of the sprayer 35 causes the cleaning liquid 15 to stir. It is possible to easily remove contaminants from food and obtain excellent cleaning performance. Further, the lid 36 provided in the cleaning tank 14 can prevent the cleaning liquid 15 from splashing outside the food cleaning device, and the cleaning liquid 15 splashed by the lid 36 can be repelled toward the food. It is possible to clean the entire exposed part.

現することができる。As described above, according to the present invention, it is possible to reduce the viscosity of the cleaning liquid by subjecting the cleaning liquid for cleaning foods to reduction treatment (controlling the redox potential to the lower side) by the potential control means. The permeability of the cleaning liquid into food is improved, the contaminants adhering to the recesses on the food surface can be easily eluted and removed, and excellent cleaning performance can be realized. This can provide hygienic and safe food. Further, since the reduction treatment of the cleaning liquid by the potential control means can be performed in the cleaning tank,
A compact cleaning device can be realized without the need for a reduction tank.

液を得ることができる。Further, since the cleaning liquid is provided with the surface activity by the liquid reforming means, the wettability of the cleaning liquid with respect to the organic food surface is improved similarly to the reduction treatment by the potential control means described above. Permeate into the concave portion of the food surface, and the contaminants adhering to the concave portion can be eluted or can be easily desorbed, and excellent cleaning performance can be obtained. Further, the cyclosilicate compound that constitutes the liquid reforming means is chemically stable, and the compound component does not dissolve in the cleaning liquid, so that a highly safe food cleaning liquid can be obtained.

の洗浄液を得ることができる。Further, by using the potential control means and the liquid reforming means in combination, the permeability to food can be further improved, so that excellent cleaning performance can be realized in a short time. Further, the pH of the cleaning liquid treated by the potential control means and the liquid reforming means is almost the same as that before the treatment, and since the above-mentioned treatment changes the properties of the cleaning liquid itself, there is a problem of corrosion of the cleaning tank. Is reduced, the selection range of materials and parts to be used is widened, and a highly safe food cleaning solution can be obtained.

自身の破損や傷の発生を防止することができる。Moreover, since the swirling flow generating means generates a swirling flow around the vertical direction of the cleaning tank in the cleaning liquid for washing the food, the physical energy of the swirling flow causes contamination attached to the food surface. The substance can be mechanically desorbed and removed. Moreover, since the action of the potential control unit and the liquid reforming unit described above can be promoted by the generation of the swirling flow, excellent cleaning performance can be realized in a short time. Further, since the food suspended in the cleaning liquid moves or rotates along with the swirling flow about the vertical direction of the cleaning tank, the collision of the food with the wall surface of the cleaning tank is suppressed, and the food itself is not damaged or damaged. Occurrence can be prevented.

分全体の洗浄が可能となる。Further, since the cleaning liquid is sprayed onto the exposed portion of the food by the liquid spraying means, the contaminants can be mechanically removed by the physical energy sprayed from the liquid spraying means. On the other hand, in the portion immersed in the cleaning liquid, the cleaning liquid is subjected to reduction treatment by the potential control means, and further the surface modification is imparted by the liquid reforming means. Due to the stirring action of the cleaning liquid due to the jet pressure of the body, contaminants can be easily removed from food, and excellent cleaning performance can be obtained. In addition, the lid provided in the washing tank can prevent the washing liquid from splashing out of the food washing device, and the lid can splash the washing liquid back toward the food so that the entire exposed portion of the food is washed. Is possible.
