The control module 280 may maintain the on state of the bypass valve 35 and the main valve 9 upon completion of the first hot water supply process. The control module 280 may maintain the on state of the gas outlet valve 73 upon completion of the first hot water supply process. The control module 280 may maintain the on state of the exhaust valve 156 upon completion of the first hot water supply process. During the first hot water supply process, water may be introduced into the beverage manufacturing pack 12, and the beverage manufacturing pack 12 may be expanded by the introduced water, and the beverage manufacturing pack 12 and the fermentation tank 112 Some of the air between) may be pushed by the expanded beverage preparation pack 12 to flow into the air supply passage 154 and may be exhausted to the outside through the exhaust valve 156.

The control module 280 may turn on the air injection pump 82 at the start of the air injection process. In addition, the control module 280 may control the flow path switching valve 20 so that the air injection flow path 81 and the bypass flow path 4C communicate with each other at the start of the air injection process, and close the air supply opening/closing valve 159 Can be controlled.

While the air injection pump 82 is on, the air pumped by the air injection pump 82 can flow into the bypass flow path 4C through the air injection flow path 81, and drink through the main valve 9 It may be introduced into the manufacturing pack 12. In this way, the air introduced into the beverage manufacturing pack 12 may collide with the liquid malt, thereby helping the malt and hot water to be more evenly mixed (Mixing).

As air is introduced into the beverage manufacturing pack 12, the beverage manufacturing pack 12 may be expanded, and some of the air between the beverage manufacturing pack 12 and the fermentation tank 112 is expanded. It may be pushed into the air supply passage 154 and may be exhausted to the outside through the exhaust valve 156.

When the pressure sensed by the pressure sensor 72 is greater than or equal to the set pressure, the control module 280 may complete the air injection process and may turn off the air injection pump 82 to complete the air injection process.
