Description

  The present invention relates to a manufacturing apparatus for manufacturing sanitized seawater.

  The sterilized seawater in the present invention is water prepared by diluting electrolyzed water having sterilizing ability, which is generated by a diaphragmless membrane electrolysis or a diaphragm membrane electrolysis using clear seawater as electrolyzed water, with clear seawater, Also, water prepared by diluting electrolyzed water having sterilizing ability produced by non-diaphragm electrolysis or diaphragm electrolysis using dilute salt water as electrolyzed water with clear seawater, and each of these dilutions Water prepared by neutralizing the effective chlorine component contained in the electrolyzed water (neutralizing sterilizing ability) to prepare a sterilized state or a state close to sterilization. The sterilized seawater is used for marine organism breeding and aquaculture water, water for sterilizing and washing fresh seafood, water for maintaining freshness when transporting fresh seafood, and equipment and machinery installed in places that handle fresh seafood. Used for various purposes such as cleaning water.

  When the sanitized seawater is used for these purposes, the effective chlorine component contained in the electrolyzed water, which is the main component of the sanitized seawater, does not affect the marine organisms that are subject to breeding and aquaculture. The electrolytically generated water is diluted with clear seawater so as to have a concentration. In addition, the diluted electrolyzed water having the effective chlorine component adjusted to this level is prepared in a sterilized state or near-sterile state by further neutralizing the effective chlorine component depending on the application.

  The electrolyzed water constituting the sanitized seawater has a sterilizing action (sterilizing ability) of an effective chlorine component generated during electrolysis of the electrolyzed water. When diluting the electrolyzed water, the clarified water is a dilution water. Aseptic bacteria in seawater are sterilized and become sterile. This eliminates the adverse effects of the sanitized seawater on marine organisms and fresh fish and shellfish, and the sanitized seawater is used for marine organisms for breeding and aquaculture, water for sterilizing and washing fresh seafood, It is used for various purposes such as freshness-keeping water and cleaning water for equipment and machinery installed in a place where fresh seafood is handled.

It has already been proposed to use diluted electrolyzed water prepared by diluting electrolyzed water having sterilizing ability with water or seawater for washing and sterilizing live fish and shellfish (see Patent Document 1). In addition, a method for producing water for sterilization adjusted to a predetermined pH by diluting electrolyzed water having sterilizing ability with clear water has already been proposed (see Patent Document 2).

Assuming that a predetermined amount of sanitized seawater in the storage tank 10c is consumed while the sanitized seawater in the second storage tank 10c is being derived, the surface of the sanitized seawater in the second storage tank 10c is set. In the case of lowering to the lowest position, the lower float switch 12a in the tank body 11 is turned off. Based on the OFF operation of the lower float switch 12a, the control device detects that the water surface of the sterilized seawater in the second storage tank 10c has reached the set minimum position, and performs electromagnetic switching of the dilution water introduction means 20c. By switching the valve 24c, the dilution water is introduced into the second storage tank 10b through the second introduction conduit 24b.
