The controller 109 may initiate a water supply step (S200) of supplying water to the beer production pack 12 during the beer production course. The water supply step S200 may be a liquid malt formation step of forming liquid malt by evenly mixing malt with hot water.

Further, the controller 109 may turn off the gas discharge valve 73 upon completion of the water supply step (S200).

The beer manufacturing apparatus may be controlled so that air is introduced into the beer manufacturing pack 12 during the water supply step (S200) as described above.

In addition, the controller 109 first introduces hot water into the beer manufacturing pack 12, then injects air into the beer manufacturing pack 12, and finally, hot water into the beer manufacturing pack 12. After the second inflow, it is possible to complete the water supply step (S200).

The water in the water tank 51 may be supplied to the beer manufacturing pack 12 as in the first hot water supply process, and new hot water may be additionally supplied to the beer manufacturing pack 12. The controller 109 may determine the completion of the second hot water supply process according to the flow rate sensed by the flow meter 56 during the second hot water supply process. When the flow rate sensed by the flow meter 56 reaches the set flow rate during the second hot water supply process, the controller 109 determines that the second hot water supply process is complete, and operates the water supply pump 52 and the water supply heater 53.

Hereinafter, the first fermentation (S900) and the second fermentation (S1000) will be described.

Hereinafter, configurations and operations different from those of the above-described embodiments will be described, and configurations that are the same or similar to those of the above-described embodiments are omitted to avoid redundant descriptions.

14 is a configuration diagram of a control system for primary and secondary fermentation of a beer production apparatus according to an embodiment of the present invention, and FIG. 15 is a control system for primary fermentation by a beer production apparatus according to an embodiment of the present invention. A flow chart showing a sequence, FIG. 16 is a graph showing a pressure change over time during a first fermentation, and FIG. 17 is a flow chart showing a control sequence of a second fermentation by a beer manufacturing apparatus according to an embodiment of the present invention.

The primary fermentation can be done in an open system. That is, air can enter and exit the beer manufacturing pack 12. When the primary fermentation proceeds, alcohol and carbon dioxide may be produced.

The first fermentation can proceed for approximately 5 to 8 days. When the first fermentation is complete, the second fermentation can begin.

Secondary fermentation can take place in a closed system. That is, air cannot enter and exit the beer manufacturing pack 12. However, since carbon dioxide is generated during the fermentation process, the beer manufacturing pack 12 may be overpressured. Therefore, the internal gas must be properly taken out so that the beer production pack 12 is not overpressured.

The beer manufacturing apparatus may include a controller 109 for primary fermentation and secondary fermentation. The controller 109 controls the gas discharge passage 71, the pressure sensor 72, the gas on-off valve 73, the air filter 74, the gas discharge relief valve 75, and the storage unit 109D for fermentation. I can.

The storage unit 109S may store a pressure value measured by the pressure sensor 72. In addition, a pressure value corresponding to the reference value may be stored. The controller 109 may control the storage unit 109S to store the pressure value and load the stored pressure value.

The control system for fermentation includes: a fermentation tank assembly 11 having a fermentation tank with an opening and a fermentation tank cover for opening and closing the opening; A beer production pack 12 inserted into the fermentation tank and accommodated through the opening and containing beer material therein; A gas outlet passage 71 connected to the fermentation tank lid; A gas on-off valve 73 installed in the gas outlet passage 71; And a controller 109 for controlling the gas opening/closing valve 73 during fermentation of the beer material.

The primary fermentation can proceed as an open system. The controller 109 may control the gas opening/closing valve 73 to be turned on. When the gas on-off valve 73 is turned on, the gas outlet passage 71 may be opened (S901).

The first fermentation may proceed so that the first time elapses with the gas opening/closing valve 73 turned on and the gas extraction passage 71 opened (S902).

The control system can determine when the primary fermentation is complete. When the first fermentation is completed, the second fermentation can begin, so it is necessary to judge that the first fermentation is completed at an appropriate time and start the second fermentation.

To this end, the controller 109 may use a pressure sensor 72 installed in the gas outlet passage 71. The controller 109 may detect a pressure change in the gas extraction passage 71 using the pressure sensor 72, and thus determine the completion timing of the primary fermentation.

When the first time elapses after the gas outlet passage 71 is opened, the controller 109 may control the gas opening/closing valve 73 to be turned off. When the gas on-off valve 73 is turned off, the gas outlet passage 71 may be closed (S903).

When the gas outlet passage 71 is closed, the controller 109 may control the pressure sensor 72 to measure the pressure. In addition, the controller 109 may store the pressure value measured by the pressure sensor 72 as the first pressure value P1 in the storage unit 109S (S904). The first pressure value P1 measured immediately after the open gas outlet passage 71 is closed may be a value close to atmospheric pressure.

The controller 109 may control the gas opening/closing flow path so that the gas extraction flow path 71 is closed while the second time elapses (S905).

When the second time elapses, the controller 109 may control the pressure sensor 72 to measure the pressure. In addition, the controller 109 may store the pressure value measured by the pressure sensor 72 as the second pressure value P2 in the storage unit 109S (S906).

While the gas extraction passage 71 is closed, fermentation may proceed inside the beer manufacturing pack 12, and carbon dioxide may be generated due to the fermentation. Accordingly, the second pressure value P2 may be greater than the first pressure value P1 due to the generation of carbon dioxide.

When the second pressure value P2 is stored, the controller 109 may control the gas on/off valve 73 to be turned on. When the gas on-off valve 73 is turned on, the gas outlet passage 71 may be opened (S907). At this time, carbon dioxide generated by fermentation may be taken out of the beer production apparatus along the gas extraction passage 71.

The controller 109 may control the gas opening/closing flow path so that the gas extraction flow path 71 is opened while the third time elapses (S908).

The controller 109 may calculate a pressure change amount (ΔP = P2-P1) using the second pressure value P2 and the first pressure value P1 stored in the storage unit 109S (S909). The pressure change amount (ΔP) may be a positive number. Alternatively, the controller 109 may calculate a value obtained by dividing the pressure change amount ΔP by the second time.

The controller 109 may compare and calculate whether the pressure change amount ΔP is smaller than the first reference value (S910). The first reference value may be a value previously stored in the storage unit 109S.

When the pressure change amount ΔP is greater than the first reference value, the controller 109 determines that the primary fermentation has not been completed and controls the gas on-off valve 73 to be turned off. And the previous steps (S903 to S909) can be repeated.

When the pressure change amount ΔP is less than the first reference value, the controller 109 determines that the primary fermentation is completed and controls the gas on-off valve 73 to be turned off (S911). And the controller 109 may end the first fermentation and start the second fermentation step.

That is, the controller 109 can calculate the fermentation degree by calculating the pressure change amount ΔP. In addition, the controller 109 may determine whether to end the first fermentation based on the degree of fermentation.

Looking at the graph showing the amount of pressure change (ΔP) over time, the amount of pressure change (ΔP) may gradually increase over time. After the pressure change amount ΔP reaches the maximum value, the pressure change amount ΔP may gradually decrease over time.

The amount of pressure change (ΔP) over time may be related to the generation rate of carbon dioxide generated by fermentation in the beer manufacturing pack 12. That is, the carbon dioxide generation rate gradually increases at the beginning of the first fermentation, but may gradually decrease after reaching the maximum rate.

The controller 109 may repeatedly measure the pressure change amount ΔP, and when the pressure change amount ΔP becomes smaller than the first reference value, it may determine that the first fermentation has been completed.

In the graph showing the pressure change amount ΔP over time, the first reference value may be a value corresponding to two times. However, since the first fermentation can proceed for approximately 5 to 8 days, if the pressure change (△P) becomes smaller than the first reference value after a certain time after the first fermentation starts, it can be determined that the first fermentation is complete have.

In the graph of the pressure change amount (△P) over time, the vertical axis may be a value obtained by dividing the pressure change amount (△P) by the second time instead of the pressure change amount (△P).

When the gas on-off valve 73 is turned off (S1001) and the primary fermentation is terminated, the secondary fermentation may be started.

In the secondary fermentation, the controller 109 may determine that the secondary fermentation has been completed when the fermentation proceeds for a predetermined time without separately calculating the fermentation degree. The controller 109 may control the gas opening/closing valve 73 to be turned off while the secondary fermentation is in progress. When the gas opening/closing valve part is turned off, the gas outlet passage 71 may be closed.

However, since carbon dioxide is generated during the fermentation process, the beer manufacturing pack 12 may be overpressured. Therefore, the internal gas must be properly taken out so that the beer production pack 12 is not overpressured.

The controller 109 may control the pressure sensor 72 to measure the pressure P (S1002).

The controller 109 may compare and calculate whether the measured pressure P is less than the second reference value (S1002). The second reference value may be a value previously stored in the storage unit 109S.

When the measured pressure P is less than the second reference value, the controller 109 may control the gas on-off valve 73 to maintain the off state.

When the measured pressure P is greater than the second reference value, the controller 109 may compare and calculate whether the measured pressure P is greater than the third reference value (S1004). The third reference value may be a value previously stored in the storage unit 109S.

When the measured pressure P is less than the third reference value, the controller 109 may control the gas on-off valve 73 to maintain the off state.

When the measured pressure P is greater than the second reference value, the controller 109 may control the gas on/off valve 73 to be turned on (S1005). When the gas on-off valve 73 is turned on, the gas outlet passage 71 may be opened. At this time, carbon dioxide generated by fermentation may be taken out of the beer production apparatus along the gas extraction passage 71.

When the fourth time elapses after the gas outlet passage 71 is opened (S1006), the controller 109 may control the gas opening/closing valve 73 to be turned off (S1007). When the gas on-off valve 73 is turned off, the gas outlet passage 71 may be closed.

The controller 109 may repeat the previous steps (S1001 to S1008) when the gas on-off valve 73 is turned off and the fifth time elapses (S1008).

The gas discharge passage 71 may further include a gas discharge relief valve 75. The gas discharge relief valve 75 may prevent the pressure of the beer production pack 12 from rapidly increasing.

The configuration included in the gas discharge passage 71 is a gas discharge relief valve 75, a pressure sensor 72, a gas on-off valve 73, and an air filter 74 along the gas discharge direction of the beer production pack 12. Can be

The controller 109 may calculate the amount of carbonated beer in the first fermentation and the second fermentation. The solubility of carbon dioxide according to temperature and pressure may be previously stored data. The controller 109 may measure the pressure inside the beer production pack 12 and the temperature inside the fermentation tank. Accordingly, the controller 109 may calculate the amount of carbonated beer in real time by comparing the previously stored carbon dioxide solubility data with the measured pressure or temperature.

Specifically, the controller 109 may measure the pressure using a pressure sensor while the gas on-off valve 73 is open during the primary fermentation, and may calculate the amount of carbonic acid. During the secondary fermentation, the pressure can be measured using the pressure sensor 72 while the gas opening/closing valve 73 is closed, and the amount of carbonic acid can be calculated.

Due to carbon dioxide generated during the secondary fermentation, the inside of the beer production pack 12 may be subjected to overpressure. In addition, the controller 109 may lower the pressure inside the beer manufacturing pack 12 by turning on the gas on/off valve 73. The controller 109 may repeatedly turn on and off the gas on-off valve 73 during the secondary fermentation. In addition, the controller 109 may determine that the secondary fermentation is completed and beer production is completed if the gas on-off valve 73 is not turned on for a predetermined time during the secondary fermentation. In addition, the controller 109 may determine that the secondary fermentation is completed and the beer production is completed when a predetermined time elapses after the gas opening/closing valve 73 is turned off during the secondary fermentation.
