及びランニングコストを嵩ませるという問題があった。Since the hollow fiber gas permeable membrane used as the deoxidizing membrane in the deoxidizing membrane section 31 has a low pressure resistance, the pressure difference between the pressure of the treated water and the degassing section is increased to increase the treated water. It is difficult to efficiently degas the dissolved oxygen and other gases that adversely affect the quality of the product liquid. Further, in order to perform deaeration with a limit value that does not damage the hollow fiber gas permeable membrane, it is necessary to perform pressure control with high accuracy, which causes a problem of increasing manufacturing cost and running cost.

Nitrogen gas is blown into the treated water flowing through the treated water supply pipe by a gas blowing device to form treated water (bubble liquid) containing a large number of fine bubbles of carbon dioxide gas or nitrogen gas, and then treated water (bubble liquid). ) Is supplied to the upper part of the vacuum tank and flows downward to the lower part of the vacuum tank (either by swirling with a spiral water channel to the lower part of the vacuum tank or through the holes of the perforated plate to the lower part of the vacuum tank. (By making it flow down countercurrently), while keeping the bubble-liquid contact time long, it is allowed to flow into the treated water retention space above the porous hollow fiber membrane unit, during which the quality of the product liquid is adversely affected. Air and oxygen bubbles and gas, and excess carbon dioxide gas or nitrogen gas are degassed from the treated water with a vacuum pump, and then the treated water that has accumulated in the treated water retention space is provided in the lower part of the vacuum tank. By passing through the filamentous membrane unit, the bubble-liquid contact time is kept long, and the gas is allowed to flow into the lowermost part of the vacuum tank, during which the above-mentioned gas that has not been degassed in the degassing process to the treated water retention space is vacuum pumped. To degas the treated water. Then, the degassed treated water that has flowed into the lowermost portion of the vacuum tank is taken out from the lower portion of the vacuum tank through the treated water delivery pipe and sent to the next step. The reason why the carbon dioxide gas or nitrogen gas is blown into the treated water flowing through the treated water supply pipe to form fine bubbles as described above is to promote the mixing of carbon dioxide gas, etc. And let
This is for facilitating removal of carbon dioxide gas and the like contained in the liquid thereafter by degassing and lowering the concentration thereof. If the beverage is non-carbonated and carbon dioxide should not be mixed, nitrogen gas is used.

させることができる。As described above, the deaerator of the present invention sends the treated water to the treated water supply pipe → the gas blowing device → the vacuum tank, while at the same time supplying the carbon dioxide gas or the nitrogen gas which does not adversely affect the quality of the product liquid. The treated water is blown into the treated water flowing through the treated water supply pipe by a gas blowing device, and the treated water is treated water containing a large number of fine bubbles of carbon dioxide gas or nitrogen gas (bubble liquid),
Then, the treated water (air bubble liquid) is supplied to the upper part of the vacuum tank and flows downward toward the lower part of the vacuum tank (whether it flows downward toward the lower part of the vacuum tank while swirling by the spiral water passage, or each hole of the perforated plate). Through the flow through the vacuum tank toward the lower part of the vacuum tank) to keep the bubble liquid contact time longer, and to flow into the treated water retention space above the porous hollow fiber membrane unit, during which air that adversely affects the quality of the product liquid A porous hollow fiber membrane unit in which oxygen bubbles and gas and excess carbon dioxide gas or nitrogen gas are degassed from the treated water by a vacuum pump, and then the treated water retained in the treated water retention space is provided in the lower part of the vacuum tank. By passing through, the air bubble liquid is allowed to flow to the lowermost part of the vacuum tank while maintaining the contact time for a long time. Degassing from the treated water by the vacuum pump the gas that has not been degassed degassing step in.
Then, the degassed treated water that has flowed into the bottom of the vacuum tank is taken out from the lower part of the vacuum tank through the treated water delivery pipe and sent to the next process, so the dissolved oxygen in the treated water and other gases that adversely affect the quality of the product liquid Can be efficiently degassed from the treated water.
