Dissolved liquid can be produced continuously and quickly. The mixing system does not need to be at a high pressure particularly for the purpose of dissolution, nor does it need to be at a special low temperature such as a carbocooler.

る。Therefore, even when increasing the production of carbonated beverage products, the carbon dioxide gas absorption step does not become a bottleneck in product production. In addition, since the liquid temperature does not need to be kept low in the bottling process and the device can be operated near normal temperature, dew condensation does not occur in the bottle mouth and the crown portion, and the amount of heating heat in the heat sterilization process after the bottling process can be saved.

来る。Further, the carbon dioxide dissolving apparatus of the present invention can be used as a deaerator since a dissolved gas such as oxygen can be separated and removed from a liquid to be dissolved. It can also be applied to various conditions and processes (dissolution and generation of anaerobic liquid atmosphere) in which the dissolution of oxygen is an obstacle.

実に立証される。Conventionally, it was generally known that a static mixer is simply used for the purpose of gas-liquid mixing. However, according to the present invention, the effect of the simple mixing expected from the operation of the conventional gas-liquid mixing is incomparable. A high dissolution effect was obtained. The effect is clearly demonstrated by the fact that a concentration as high as 4 times as high as that of the high-pressure melting method of the carbocooler was achieved without increasing the pressure.
