窒素処理水生成装置、窒素処理水生成方法、及び、窒素処理水により処理する生鮮魚介類の鮮度保持処理法

Japanese Patent JP5180405

B2

In order to greatly increase the efficiency of reducing the amount of dissolved oxygen in treated water, this nitrogen-treated-water generating device is provided with: a circulation duct that circulates a fluid; a tank that holds treated water and that is provided partway along the circulation duct; a nitrogen gas supplying unit that is connected partway along the circulation duct in order to supply nitrogen gas to the treated water that flows out from the tank; and a fluid mixing processing unit provided partway along the circulation duct in order to mix the nitrogen gas with the treated water while the nitrogen gas forms a bubble group having ultrafine bubbles by means of applying shearing force to the liquid-gas mixed phase of treated water and nitrogen gas supplied from the nitrogen gas supplying unit. The treated water mixed with the bubble group and emitted from the fluid mixing processing unit is circulated within the tank, and by diffusing the oxygen dissolved in the treated water into the nitrogen gas that is in the form of minute bubbles within the tank, the minute nitrogen gas into which the oxygen diffuses is allowed to float up within the treated water and is allowed to escape from the treated water.
