The beer maker may perform a fermentation step (S900) (S1000) of fermenting the material in the beer production pack 12 after the dispenser residual water removal step (S800) is completed.

The fermentation step (S900) (S1000) may include a primary fermentation well (S900) and a secondary fermentation well (S1000) that are sequentially performed.

In the beer making machine, alcohol and carbon dioxide are simultaneously produced in the beer material during the fermentation step (S900) (S1000). The fermentation step (S900) (S1000) prioritizes the production of alcohol (ethanol) and can first carry out the primary erection tablet (S900) that does not capture carbon dioxide, and generates and captures carbon dioxide after the primary erection tablet (S900).

The controller 109 may maintain the pressure inside the beer production pack 12 within the set pressure range of the fermenter while opening and closing the gas extraction valve 73 while comparing the pressure detected by the pressure sensor 72 with the set pressure.

Here, the set pressure is a pressure set lower than the target pressure of the fermenter, and the set pressure is a pressure set lower than the target pressure of the fermenter by the reference pressure. For example, when the fermenter target pressure is 1.5 bar, the reference pressure may be any one of 0.045 bar to 0.075 bar, which is within 3% to 5% of the fermenter target pressure.

When the detection value P of the pressure sensor 72 exceeds the set pressure in the secondary ignition effect well S1000, the gas extraction valve 73 is opened, and the detection value P of the pressure sensor 72 is equal to or less than the set pressure. If this is the case, the gas extraction valve 73 may be closed.

The secondary fermentation effect tablet (S1000) is a process of additionally fermenting beer ingredients while determining whether to end fermentation at a set time (for example, 12 hours or 24 hours).

The secondary fermentation effect tablet (S1000) may be repeated with a close fermentation process and an open fermentation process over time, and the number of open fermentation processes per set time gradually decreases as fermentation continues.

The controller 109 may count the number of openings of the gas ejection valve 73 to determine the end point of the secondary ignition effect well S1000, and the gas ejection valve 73 may not be opened for a set time or the gas If the number of times the take-off valve 73 is opened is less than the set number of times, it can be determined by itself that the secondary repelling effect well S1000 has ended.

The controller 109 may determine the end of the secondary outbreak effect definition according to the number of open fermentation processes performed during the set time. Detailed control of the secondary outbreak effect tablet S1000 will be described in detail with reference to FIG. 8.

The fermentation step (S900) (S1000) may be terminated if the number of openings of the gas extraction valve 73 during the set time is less than the set number.

The beer maker may perform the aging step (S1100) after the end of the fermentation step (S900) (S1000). The aging step (S1100) may be performed when the secondary erection effect (S1000) ends.

During the aging step (S1100), the gas extraction valve 73 may be kept closed for a aging set time.

The aging set time may be set longer than the set time.

The aging step (S1100) may be performed during the aging set time. The aging step (S1100) may end when the aging set time has elapsed.

The controller 1090 may control the compressor 131 such that the temperature of beer during the aging set time is maintained between the upper limit of the aging set temperature and the lower limit of the aging set temperature.

The controller 109 may turn off the compressor 131 when the temperature sensed by the temperature sensor 16 is less than or equal to the lower limit of the aging set temperature, and if the temperature sensed by the temperature sensor 16 is greater than or equal to the upper limit of the aging set temperature. , The compressor 131 can be turned on.

The controller 109 can keep the gas blowing valve 73 open for a set time after opening the gas blowing valve 73. When the time measured by the timer reaches the open setting time after the gas extraction valve 73 is opened, the controller 109 changes the difference between the first pressure P1 and the second pressure P2 stored in the data storage unit. It can be compared with the target pressure change.(S907)(S908)

Here, the difference (P2-P1) between the first pressure (P1) and the second pressure (P2) stored in the data storage unit may be a change value (P) of the pressure detected by the pressure sensor 72 during the close set time. .

The controller 109 may terminate the primary eruption effect well S900 when the change value P=P2-P1 of the pressure is less than the target pressure change amount.

When the pressure change value (P=P2-P1) is equal to or greater than the target pressure change amount, the controller 100 returns to the process of closing the gas extraction valve 73 to re-detect the fermentation degree, and the gas extraction valve 73 ), the new first pressure P1 sensed by the pressure sensor 72 at the time of closing is stored in a data storage unit (not shown), and the process can be repeated thereafter (S908) (S903).

When the sensed value P of the pressure sensor 72 exceeds the set pressure in the secondary erection valve S1000, the gas extraction valve 73 may be opened. (S1002) (S1003)

In addition, in the secondary erection valve S1000, when the detection value P of the pressure sensor 72 is equal to or less than the set pressure, the gas extraction valve 73 may be closed. (S1002) (S1001)

The controller 109 may open and close the gas extraction valve 73 while comparing the pressure sensed by the pressure sensor 72 with the set pressure until the elapsed time after the second fermentation is started reaches the set time. . (S1001) (S1002) (S1003) And the controller 109 can integrate the number of openings of the gas outlet valve 73 for a set time.

When the set time is reached after the second fermentation is started, the controller 109 may compare the accumulated number of times the gas extraction valve 73 is opened with the set number of times. (S1004) (S1005)

The secondary ignition effect well (S1000) may be terminated if the number of openings of the gas extraction valve 73 during the set time is less than the set number of times (S1005) (S1100).

If the number of times the opening of the gas extraction valve 73 is greater than or equal to the set number of times during the set time, the secondary ignition effect well S1000 opens the gas extraction valve 73 according to the detection value P of the pressure sensor 72 as described above. , It can be repeated to close.(S1001)(S1002)(S1003)(S1004)

The set time is a predetermined time to determine the end of the second fermentation, and may be set shorter than the aging set time in the attribute step S1100.

For example, when the set time is set to 12 hours, the secondary ignition effect well S1000 may be determined to be terminated according to the number of times the gas extraction valve 73 is opened for 12 hours.

In addition, a specific number of times may be set, such as 1 time, 2 times, or 3 times.

When the set number of times is set to one, the secondary ignition effect well S1000 may be terminated if the gas draw valve 73 is not opened for a set time.

As another example, when the set number of times is set to 3 times, the secondary ignition effect well S1000 may be terminated if the gas extraction valve 73 is not opened or opened once or twice during the set time. On the other hand, if the gas draw valve 73 is opened three or more times during the set time, it may not be terminated.

The second foot effect tablet (S1000) is set at a predetermined time period, and it may be determined whether or not the end. When determining whether or not the first end is finished, the second foot effect correction (S1000) resets the timer counting time to 0 when the second foot effect correction (S1000) is not finished, and repeats the above process again for the same set time. (S1006)(S1001)(S1002)(S1003)(S1004)

As the fermentation of beer gradually ends, the change in pressure detected by the pressure sensor 72 gradually decreases, and the secondary fermentation effect well (S1000) performs a determination of the end of the secondary fermentation at least once, and then a set time In the meantime, if the number of openings of the gas draw valve 73 is less than the set number, it may be terminated.

On the other hand, the flow paths such as the main flow path 2, the beer flow path 61, the gas flow path 71, the air injection flow path 81, and the air supply flow path 154 described in this embodiment can pass through the fluid. It can be formed by a hose or tube, it is also possible to be composed of a plurality of hoses or a plurality of tubes that are continuous in the longitudinal direction, at least two other valves, pumps, branch pipes or other pipes and other arrangements disposed therebetween Of course, it is also possible to include a hose or tube.
