The user can input a drink manufacturing command through an input unit provided in the controller 109, a remote controller, or a portable terminal. The controller 109 can control the beverage maker to the beverage making step according to the input of the beverage manufacturing instruction.

The controller 109 can start water supply step S200 for supplying water to the pack 12 during the beverage manufacturing step. The water supplying step (S200) may be a liquid malt formation step of mixing the malt in the pack 12 with hot water to form liquid malt.

The water heated by the water heater 53 can pass through the main flow path 2 and the bypass valve 35 and can flow into the pack 12 through the main valve 9. Hot water introduced into the pack 12 through the main flow path 2 can be mixed with the malt contained in the pack 12 and the malt in the pack 12 can be mixed with water and gradually diluted. On the other hand, since the hot water is supplied to the pack 12, the malt contained in the pack 12 can be quickly and uniformly mixed with hot water.

The pack 12 may gradually expand upon the inflow of water as described above and the air between the pack 12 and the fermenter 112 may partially flow into the air supply passage 154 as the pack 12 is inflated And the air that has flowed into the air supply passage 154 can be exhausted to the exhaust valve 156.

As the air is introduced into the pack 12, the pack 12 can be expanded and a part of the air between the pack 12 and the fermentation tank 112 is pushed by the pack 12 to be inflated, And can be exhausted to the outside through the exhaust valve 156.

The controller 109 can complete the air injection process and turn off the air injection pump 82 to complete the air injection process if the pressure sensed by the pressure sensor 72 is higher than the set pressure. The controller 109 can keep the main valve 9, the bypass valve 35, the gas opening / closing valve 73, and the exhaust valve 156 ON at the completion of the air injection process.

The controller 109 can turn on the water supply pump 52 and the water heater 53 at the start of the second hot water supply process. The water in the water tank 51 can be supplied to the pack 12 as in the case of the first hot water supply process and the hot water can be additionally supplied to the pack 12.

The controller 109 can control the compressor 131 and the expansion mechanism 133 of the refrigeration cycle apparatus 13 to cool the fermentation tank 112. [ The refrigerant compressed in the compressor 131 can be expanded by the expansion mechanism 133 after being condensed in the condenser 132. The refrigerant expanded by the expansion mechanism 133 can pass through the evaporator 134, take the heat of the fermentation tank 112, and evaporate.
