In more detail, the controller 281A may control the refrigeration cycle device 13 for cooling the fermentation tank 112. The refrigerant may be evaporated while passing through the evaporator 134 to take away heat from the fermentation tank 112. When the refrigeration cycle device 13 is driven, the fermentation tank 112 may be gradually cooled, and the fermentation container 12 accommodated in the fermentation tank 112 and the liquid malt accommodated in the fermentation container 12 may be cooled.

When cooling the fermentation tank 112 as described above, the evaporator 134 can cool the fermentation container 12, and the controller 281A is frozen according to the temperature sensed by the temperature sensor 16 installed in the fermentation tank 112. The cycle device 13 can be controlled.

The controller 281A may control the compressor so that the temperature sensed by the temperature sensor 16 is maintained at a set temperature (eg, 35° C.). In more detail, the controller 281A may turn on the compressor of the refrigeration cycle device 13 when the temperature sensed by the temperature sensor 16 exceeds the compressor ON temperature (eg, 35.5° C.). The control module 280 may turn off the compressor when the temperature sensed by the temperature sensor 16 is less than or equal to the compressor off temperature (eg, 34.5° C.).

During the additive input step (S500), which will be described later, the feedwater heater 53 is turned off, so the temperature of the fermentation container 12 was set during the cooling step (S300) by the water introduced into the fermentation container 12 together with the additive. It may drop slightly compared to the set temperature. For example, until then, the temperature of the fermentation container 12 is maintained at around 35°C, and when additives and water are added to the fermentation container 12 together, the temperature of the fermentation container 12 may decrease to around 30°C. Therefore, it is preferable that the set temperature in the cooling step (S300) is determined in consideration of this temperature drop.

The controller 281A may keep the exhaust valve 156 closed during the fermentation tank cooling step (S300), and the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 is external through the exhaust valve 156 It does not escape to, and the air inside the fermentation tank 112 can be quickly cooled.

Exceptionally, when the temperature of the fermentation container 12 is lower than the set temperature even when the refrigeration cycle device 13 is turned off because the external temperature is very low, the controller 281A is the heater 14 located below the fermentation tank 112. ) Can be turned on. The controller 281A may turn on the heater 14 when the temperature sensed by the temperature sensor 16 is less than the heater on temperature. The control module 280 may turn off the heater when the temperature sensed by the temperature sensor 16 is higher than the heater off temperature.

On the other hand, the beverage manufacturing step may include an air supply step (S400).

In more detail, in the beverage maker, after the fermentation tank cooling step (S300) is started and the compressor of the refrigeration cycle device 13 is turned on, the temperature sensed by the temperature sensor 16 is at least once less than the compressor off temperature, An air supply step (S400) of mixing liquid malt by supplying air into the fermentation container 12 may be performed. Alternatively, in the beverage maker, when the fermentation tank cooling step (S300) as described above is started and the heater 14 is turned on, the temperature sensed by the temperature sensor 16 is at least once more than the heater off temperature, the fermentation container 12 An air supply step (S400) of mixing liquid malt by supplying air may be performed.

The beverage maker may control the refrigeration cycle device 13 and the heater 14 on and off according to the temperature sensed by the temperature sensor 16, even during the air supply step S400, and such a refrigeration cycle device 13 And the on/off control of the heater 14 may be continued until the additive input step (S500) described later is completed.

In the air supply step (S400), the controller 281A may turn on the air pump 82 and open the bypass valve 35 and the main valve 40. In addition, the controller 281A can open the gas discharge valve 73 and the exhaust valve 156, and keep the air supply valve 159 and the material supply valve 310 closed.

While the air pump 82 is on, air injected into the air injection channel 81 may flow from the first main channel 41 to the second main channel 42 through the bypass channel 43, and It may be introduced into the fermentation container 12 through the valve 40. As described above, the air introduced into the fermentation container 12 may collide with the liquid malt to help the malt and hot water to be more evenly mixed, and the air that collides with the liquid malt may supply oxygen to the liquid malt. That is, stirring and aeration can be performed.

While air is injected into the fermentation container 12, the fermentation container 12 may be expanded by the air injected into the fermentation container 12. Some of the air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 may be pushed by the expanded fermentation container 12 to flow into the air supply channel 154, and to the outside through the exhaust valve 156. Can be exhausted. Thereby, the fermentation container 12 can be easily expanded, and the air of the second main channel 42 can be quickly introduced into the fermentation container 12 and mixed with liquid malt.

The controller 281A can mix air into the liquid malt during the mixing setting time when the air pump 82 is turned on, and when the air pump 82 is turned on and the mixing setting time elapses, the air supply step (S400) can be completed. have. Upon completion of the air supply step S400, the controller 281A may turn off the air pump 82 and close the bypass valve 35. In addition, the controller 281A may close the gas discharge valve 73 and the exhaust valve 156 upon completion of the air supply step S400.

The beverage manufacturing step may include an additive input step (S500).

In more detail, the beverage maker may perform the additive input step (S500) after the air supply step (S400).

In the additive input step (S500), the first additive of the first capsule (C1), the second additive of the second capsule (C2), and the third additive of the third capsule (C3) are introduced into the fermentation container 12 Can be. At this time, the first capsule (C1) is a capsule mounted on the initial capsule mounting portion 31, the second capsule (C2) is a capsule mounted on the intermediate capsule mounting portion 32, and the third capsule (C3) is the final capsule. It is a capsule mounted on the mounting portion 33.

During the additive input step (S500), the controller 281A may turn on the feed water pump 52 and maintain the feed water heater 53 in an off state. Further, the controller 281A may keep the bypass valve 35 closed and open the material supply valve 310 and the main valve 40. Also, the controller 281A may open the gas discharge valve 73 and the exhaust valve 156.

When the water supply pump 52 is turned on, the water in the water tank 51 passes through the water supply pump 52 and the water heater 53, flows to the first main channel 41, and passes through the material supply valve 310. It may be introduced into the first capsule C1. The water introduced into the first capsule C1 may be mixed with the first additive contained in the first capsule C1, and may flow to the first connection channel 311 together with the first additive.

The fluid (a mixture of water and the first additive) introduced into the second capsule C2 through the first connection channel 311 is mixed with the second additive contained in the second capsule C2, and a second additive It may flow together with the second connection channel 312.

The fluid (water, a mixture of the first additive and the second additive) introduced into the third capsule C3 through the second connection channel 312 is mixed with the third additive contained in the third capsule C3. , It may flow to the second main channel 42 together with the third additive.

A fluid (a mixture of water, a first additive, a second additive, and a third additive) flowing through the second main channel 42 may pass through the main valve 40 and flow into the fermentation container 12. Accordingly, all of the additives contained in the capsules C1, C2, and C3 may be introduced into the fermentation container 12.

The controller 281A may complete the additive input process (S500) when the accumulated flow rate sensed by the flow meter 56 from the start of the additive input process (S500) reaches the set additive input flow rate. Upon completion of the additive injection process (S500), the controller 281A may turn off the water supply pump 52.

The beverage manufacturing step may include a step of removing residual water from the material feeder (S600).

In more detail, when the additive input step (S500) is all completed, a material feeder residual water removal step (S600) of removing residual water in the material feeder 3 may be performed.

In the material feeder residual water removal step (S600), the controller 281A may turn on the air pump 82 and keep the air supply valve 159 closed. Further, the controller 281A can open-control the material supply valve 310 and the main valve 40. In addition, the controller 281A can open-control the gas discharge valve 73 and the exhaust valve 156.

When the air pump 82 is turned on, the air injected into the air injection channel 81 may flow to the first main channel 41 and pass through the material supply valve 310 to be introduced into the first capsule C1. . The air introduced into the first capsule (C1) passes through the first capsule (C1), the second capsule (C2), and the third capsule (C3) in sequence, and the residual water remaining in each is transferred to the second main channel 42. You can blow it out. Air flowing through the second main channel 42 may be introduced into the fermentation container 12 together with residual water.

Accordingly, additives and residual water that have not yet been extracted from each capsule C1, C2, and C3 can be introduced into the fermentation container 12 without leaving any remaining.

As residual water and air are injected into the fermentation container 12 from the second main channel 42, the fermentation container 12 may be further expanded, and between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 Some of the air may be pushed by the expanded fermentation container 12 to flow into the air supply channel 154 and may be exhausted to the outside through the exhaust valve 156. Accordingly, the fermentation container 12 can be easily expanded, and air and residual water of the second main channel 42 can be quickly introduced into the fermentation container 12.

The controller 281A turns on the air pump 82 for a set time to remove residual water, and when the set time for removing residual water elapses, the material feeder may complete the step of removing residual water (S600).

When the material feeder residual water removal step (S600) is completed, the controller 281A may turn off the air pump 82 and close the material supply valve 310 and the main valve 40. In addition, the controller 281A can close the gas discharge valve 73 and the exhaust valve 156.

When the material feeder residual water removal step S600 is completed, the controller 281A may display a capsule separation message on the display 282 indicating that the capsules C1, C2, and C3 may be removed, and the user may display the material feeder ( In 3) you can remove the empty capsule.

The beverage manufacturing step may include a fermentation step (S700) (S800).

In more detail, after the completion of the material feeder residual water removal step (S600), the first fermentation step (S700) and the second fermentation step (S800) may be sequentially performed.

According to an example of the first fermentation step (S700), the first fermentation step (S700) may include a pre-fermentation process and a main fermentation process. This fermentation process can be carried out after the entire fermentation process is completed.

The entire fermentation process is a process for rapidly and actively activating the yeast added to the fermentation container 12 during the additive input step (S500).

The controller 281A may control the refrigeration cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 maintains the previous fermentation target temperature (eg, 30° C.) during the entire fermentation process. have. After the start of the entire fermentation process, the controller 281A periodically opens and closes the gas discharge valve 73, and stores the pressure value sensed by the gas pressure sensor 72 immediately after the gas discharge valve 73 is closed. It can be stored in the sub (not shown). The controller 281A may calculate the amount of change in pressure by comparing the stored pressure value with a pressure value sensed after a predetermined period of time elapses while the gas discharge valve 73 is closed. When the calculated change in pressure exceeds the pre-fermentation set pressure, the controller 281A may determine that the pre-fermentation has been completed, and may complete the pre-fermentation process.

The controller 281A may start the main fermentation process when the entire fermentation process is completed.

The controller 281A may control the refrigeration cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 maintains the main fermentation target temperature (eg, 21° C.) during the main fermentation process. have. In this case, the main fermentation target temperature may be higher than the previous fermentation target temperature.

After the start of the main fermentation process, the control module 280 periodically opens and closes the gas discharge valve 73, and stores the pressure sensed by the gas pressure sensor 72 while the gas discharge valve 73 is closed. Not shown). When the change in pressure periodically sensed by the gas pressure sensor 72 exceeds the main fermentation set pressure, the control module 280 may determine that the main fermentation has been completed, and may complete the first fermentation step S700.

However, the first fermentation step (S700) is not limited thereto, and according to another example of the first fermentation step (S700), the first fermentation step (S700) does not include the entire fermentation process and may include only the main fermentation process. have. This description will be omitted because it is redundant.

Meanwhile, the controller 281A may start the second fermentation step S800 after completion of the first fermentation step S700.

The controller 281A may control the refrigeration cycle device 13 and the heater 14 so that the temperature measured by the temperature sensor 16 becomes the secondary fermentation target temperature during the second fermentation step (S800).

During the second fermentation step (S800), since the internal pressure of the fermentation container 12 is high, there is a concern that a large noise may be generated when the gas discharge valve 73 is opened. In order to solve the above concerns, the controller 281A keeps the gas discharge valve 73 closed during the second fermentation step (S800), and opens/closes the pressure relief valve 76 provided with the noise reduction device 77. Can be controlled.

After the start of the second fermentation step (S800), the controller 281A periodically opens and closes the pressure release valve 76, and the pressure sensed by the gas pressure sensor 72 while the pressure release valve 76 is closed. Can be stored in a storage unit (not shown). When the change in pressure periodically sensed by the gas pressure sensor 72 exceeds the second fermentation set pressure, the controller 281A may determine that the second fermentation has been completed, and may complete the second fermentation step S800.

The beverage manufacturing step may include a aging step (S900).

In more detail, when both the first fermentation step (S700) and the second fermentation step (S800) are completed, the aging step (S900) may be performed.

The controller 281A can wait for the aging time during the aging step, and during this aging time, the refrigeration cycle device 13 and the heater ( 14) can be controlled.

Since the beverage maker is mainly used indoors, the temperature outside the beverage maker is generally between the upper limit of the set aging temperature and the lower limit of the set aging temperature, or higher than the upper limit of the set aging temperature. In this case, the controller 281A can turn off the compressor of the refrigeration cycle device 13 when the temperature sensed by the temperature sensor 16 is less than the lower limit of the set aging temperature, and the temperature sensed by the temperature sensor 16 If it is more than the upper limit of the set aging temperature, the compressor can be turned on.

Exceptionally, when the temperature outside the beverage maker is lower than the lower limit of the set aging temperature, the controller 281A may turn on the heater 14 when the temperature detected by the temperature sensor 16 is less than the lower limit, and the temperature sensor 16 ), the heater 14 can be turned off when the temperature sensed at is higher than the upper limit of the set aging temperature.

When the aging time of the beverage maker elapses, all beverage production may be completed.

However, in some cases, when the aging step (S900) is omitted and the second fermentation step (S800) is completed, the production of the beverage may be completed.

The controller 281A may display the completion of beverage production through the display 282 or the like.

In addition, the controller 281A may control the compressor 134 to maintain the temperature of the fermentation tank 112 between an upper limit and a lower limit of a preset drinking temperature. The controller 281A may turn on the compressor of the refrigeration cycle device 13 when the temperature sensed by the temperature sensor 16 is higher than the upper limit of the drinking temperature, and the temperature sensed by the temperature sensor 16 is less than the lower limit of the drinking temperature. When lowered, the compressor can be turned off. In this way, the beverage maker can always provide a cool beverage to the user.

The controller 281A may maintain the temperature of the fermentation tank 112 between the upper limit value and the lower limit value of the preset drinking temperature until the beverage dispensing step S1000 to be described later is completed.

The beverage maker according to an embodiment of the present invention may further include a beverage taking out step (S1000) of taking out a beverage after the beverage manufacturing is completed.

According to an example of the beverage dispensing step S1000, the beverage discharging step S1000 may include a beverage dispensing process and a dispenser cleaning process.

In the beverage dispensing step S1000, the user may dispensing the beverage by operating the dispenser 62.

After the beverage production is completed, when the user opens the dispenser 62, the controller 281A may open the main valve 40 and the beverage dispensing valve 64.

When the main valve 40 and the beverage withdrawal valve 64 are opened, the beverage in the fermentation container 12 is discharged from the fermentation container 12 by air pressure between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112. It may flow to the second main channel 42, and may flow from the second main channel 42 to the beverage dispensing channel 61 to be dispensed to the dispenser 62.

When the user closes the dispenser 62 after dispensing a portion of the beverage through the dispenser 62, the controller 281A may close the main valve 40 and the beverage dispensing valve 64. As a result, one beverage taking out process can be completed.

Thereafter, the controller 281A can turn on the air pump 82, open the air supply valve 159, and keep the exhaust valve 156 closed.

When the air pump 82 is turned on, the air injected into the air injection channel 81 flows from the first main channel 41 to the air supply channel 154, and the outer surface of the fermentation container 12 and the fermentation tank 112 It can be supplied between the inner walls of the. The air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 may pressurize the fermentation container 12 with a pressure that allows the beverage of the fermentation container 12 to rise to the second main channel 42. . This is to form a sufficient high pressure between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 so that the beverage from the fermentation container 12 can be smoothly and quickly taken out during subsequent beverage extraction.

The user can take out the beverage at least once through the dispenser 62. That is, the beverage dispensing process may be performed at least once, and the controller 281A includes a time when the dispenser 62 is opened, a time when the air pump 152 is driven, and the main valve 40 after beverage production is completed. It is possible to determine whether or not the beverage is dispensed using information such as the on-in time.

The controller 281A can close the air supply valve 159 when the beverage dispensing is completed. Further, the controller 281A may open the exhaust valve 156 for a set time of completion when the beverage dispensing is completed and the dispenser 62 is in a closed state.

During the open control of the exhaust valve 156, air between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 is exhausted to the exhaust valve 156 through the air supply channel 154 and the exhaust channel 157. The pressure of the space between the outer surface of the fermentation container 12 and the inner wall of the fermentation tank 112 may be equal to atmospheric pressure.

After turning on the exhaust valve 156, the controller 281A may close the exhaust valve 156 when the completion setting time elapses.

If the cleaning step (S1100) is not performed after the beverage dispensing is completed, or the cleaning step (S1100) does not include a main channel cleaning process to be described later, the controller 281A may use the fermentation container 12 on the display 282, etc. You may be prompted to remove the pack asking you to remove it. The user can open the fermentation lid 107 to take the fermentation container 12 out of the fermentation tank module 111.

When the fermentation reed 107 is opened as described above, if the inside of the fermentation tank 112 is a high pressure higher than the set pressure than the atmospheric pressure, the fermentation container 12 may bounce to the top of the fermentation tank 112 due to this pressure difference.

On the other hand, before the user opens the fermentation reed 107, when some of the air between the fermentation container 12 and the fermentation tank 112 is exhausted through the exhaust valve 156, when the fermentation reed 107 is opened , The fermentation container 12 does not bounce upward, and is maintained inside the fermentation tank 112.

That is, the user can safely and cleanly take out the used fermentation container 12 from the fermentation tank 112.

Meanwhile, the dispenser cleaning process may be performed after at least one beverage dispensing process.

If there is a significant time interval before the last beverage dispensing process is completed and the next beverage dispensing process is performed, there is a concern that the inside of the dispenser 62 may be contaminated by the beverage remaining in the dispenser 62.

Accordingly, when the user attempts to dispense a beverage after the dispenser cleaning setting time has elapsed from the last beverage dispensing process, the controller 281A may perform the dispenser cleaning process.

In more detail, the controller 281A may start a timer (not shown) when each beverage dispensing process is completed, and may reset the timer when the next beverage dispensing process is started. The controller 281A may perform a dispenser cleaning process when the timer passes the dispenser cleaning set time and the dispenser 62 is opened.

In addition, the controller 281A may perform a dispenser cleaning process by receiving a dispenser cleaning command from an input unit or a mobile terminal.

When the dispenser cleaning process is started, the controller 281A may display a cleaning notification on the display 282 or the like. The cleaning notification may include a content instructing the user not to bring a cup or cup to the dispenser 62.

An example of the dispenser cleaning process may include a water washing process and an air washing process.

During the water washing process, the controller 281A may turn on the feed pump 52. In addition, the controller 281A may open the sub valve 92 and the beverage dispensing valve 64 and keep the material supply valve 310 and the bypass valve 35 closed.

When the water supply pump 52 is turned on, water sucked from the water tank 51 to the water supply pump 52 may flow from the water supply channel 55B to the sub channel 91 and pass through the sub valve 92 It may flow into the dispensing channel 61 and may pass through the beverage dispensing valve 64 to be dispensed with the dispenser 62. In the process of discharging water to the dispenser 62, cleaning may be performed by being taken out together with debris and foreign substances inside the dispenser 62.

Water and foreign substances taken out of the dispenser 62 may fall into the beverage container 101 (see FIG. 2 ).

The controller 281A may complete the water washing process when the accumulated water quantity of the flow meter 56 reaches the set water washing flow rate from the start of the water washing process. In this case, the water washing set flow rate may be less than the cleaning set flow rate in the cleaning steps S100 and S1100.

The controller 281A may turn off the feed pump when the water washing process is completed. Further, the controller 281A may start the air cleaning process when the water cleaning process is completed.

The controller 281A may turn on the air pump 82 when the air cleaning process is started.

When the air pump 82 is turned on, the air injected from the air pump 82 into the first main channel 41 through the air injection channel 81 passes through the feed water heater 53 to the sub-channel 91. It flows, passes through the sub-valve 92, flows to the beverage dispensing channel 61, passes through the beverage dispensing valve 64, and may be discharged to the dispenser 62. While air is discharged to the dispenser 62, cleaning may be performed by being blown out together with the residual water remaining in the dispenser 62. Accordingly, it is possible to minimize the influence of the residual water on the taste of the beverage during the subsequent beverage extraction process.

The controller 281A may complete the air cleaning process when the air cleaning process is started and the air cleaning set time elapses. When the air cleaning process is completed, the controller 281A may turn off the air pump 82 and close the sub valve 92. This may complete the dispenser cleaning process.

When the dispenser cleaning process is completed, the controller 281A may start the beverage dispensing process again.

On the other hand, when all of the beverages in the fermentation container 12 are taken out and the controller 281A determines that the beverage is taken out, the controller 281A may further perform a beverage manufacturing step and a cleaning step S1100 after the beverage is taken out.

The beverage manufacturing step and the cleaning step S1100 after the beverage is taken out may include at least one of a first cleaning process and a second cleaning process. When the cleaning step S1100 includes the first cleaning process and the second cleaning process, the execution order of each cleaning process may not be limited.

Since the first cleaning process is the same as or similar to the cleaning step S100 before the beverage manufacturing step described above, the overlapping content will be omitted. Hereinafter, the second cleaning process will be described.

The second cleaning process is carried out in a state where the beverage is taken out and the empty fermentation container 12 is mounted, or the user removes the empty fermentation container 12 and installs a separate cleaning pack in the fermentation tank 112. It can be carried out later. Hereinafter, for convenience of explanation, a case where a separate cleaning pack is accommodated in the fermentation tank 112 will be described as an example.

When the beverage dispensing of the fermentation container 12 is completed, the controller 281A may display a container replacement notification on the display 282 or the like. The user may open the fermentation reed and remove the empty fermentation container 12 from the fermentation tank 112 and then insert a separate cleaning pack into the fermentation tank 112. Thereafter, the fermentation reed 107 can be closed.

Thereafter, the controller 281A may start a second cleaning process.

At the start of the second cleaning process, the controller 281A may turn on the feed water pump 52 and the feed water heater 53, and close the beverage dispensing valve 64. In addition, the controller 281A may open the material supply valve 310, the bypass valve 35, and the main valve 40.

At the start of the second cleaning process, the controller 281A may open the gas discharge valve 73 and the exhaust valve 156. In addition, the controller 281A can open the sub valve 92.

When the water supply pump 52 is turned on, the water in the water tank 51 flows to the water supply heater 53 and may be heated in the water supply heater 53.

Water (ie, hot water) heated by the water supply heater 53 may be divided into a sub-channel 91 and a first main channel 41 to flow.

Water flowing through the sub-channel 91 may pass through the sub-valve 92 and flow into the beverage dispensing channel 61. The water flowing through the beverage dispensing channel 61 may flow into the second main channel 42 and pass through the main valve 40 to be introduced into the cleaning pack accommodated in the fermentation tank 112.

In addition, water flowing through the first main channel 41 may be divided into a material feeder 3 and a bypass channel 43 to flow.

The water flowing to the material feeder 3 sequentially passes through the material supply valve 310, the initial capsule mounting portion 31, the intermediate capsule mounting portion 32, and the final capsule mounting portion 33 to the second main channel 43. It may flow, and may be introduced into the cleaning pack accommodated in the fermentation tank 112 through the main valve 40.

Water flowing to the bypass channel 43 may pass through the bypass valve 35 and flow to the second main channel 43, and pass through the main valve 40 to the cleaning pack accommodated in the fermentation tank 112. Can be introduced.

During the above control, the main channels 41 and 42, the bypass channel 43, the sub-channel 91, the valves installed in the respective channels, and the main channel connection part 115 may be sterilized and cleaned. In addition, each capsule mounting portion 31, 32, 33 and the connection channels 311, 312 can be sterilized and cleaned.

The controller 281A may perform the above-described cleaning during the second cleaning set time, and may complete the second cleaning process after the second cleaning set time.

The controller 281A may turn off the water supply pump 52 and the water supply heater 53 after the second cleaning setting time has elapsed, and the main valve 40, the bypass valve 35, and the material supply valve 310 ), the sub-valve 92, the gas discharge valve 73, and the exhaust valve 156 can be closed.

On the other hand, after the cleaning step (S1100) is completed, the user may open the fermentation reed 107 and take out a cleaning pack containing water that has been washed in the fermentation tank 112 for processing.

5 is a perspective view of the material feeder closed, and FIG. 6 is a perspective view of the material feeder open.

The capsules (C1) (C2) (C3) described above are exemplary, and hereinafter, instead of the capsules, beverage material capsules (C1) (C2) (C3) will be named and described. In addition, the material accommodating part is named and described as the material accommodating part 31, 32, 33.

The material feeder 3 includes a material receiving body 36 having a material receiving portion 31, 32, 33 in which the beverage material capsules C1, C2, and C3 containing the beverage material are detachably mounted, and A lead module 37 covering the material receiving portions 31, 32, and 33 may be included.

Since the beverage material capsule can be accommodated in the material feeder 3, the material receiving body 36 may be defined as a beverage material capsule receiving body.

The lid module 37 may include a lid 38 covering the material receiving body 36, and a locking operation part 371 for releasing the lock of the lid 38.

The beverage material capsule stopper 317 and the beverage material capsule (C1) (C2) (C3) may be sealed so as not to leak out. Thereby, the cleanliness of the material feeder 3 can be maintained.

In addition, a pressure sealing portion 318A may be formed on the upper surface of the pressing portion contact portion 318. Even though the beverage material capsule sealing part 317A is formed, when the material leaks through the gap between the beverage material capsules C1, C2, and C3 and the beverage material capsule stopper 317, the pressure sealing part 318A ) Can prevent the leaked material from leaking out of the material receiving portions 31, 32, and 33. Accordingly, the cleanliness of the material feeder 3 can be more effectively maintained.

However, it is of course possible that the pressure sealing portion 318A is not provided in the pressing portion contact portion 318 and a sealing (not shown) is provided on the pressing portions 47A, 47B, and 47C. The sealing may be provided to surround the lower outer circumference of the pressing portions 47A, 47B, and 47C, and may contact the inner circumference of the material receiving portions 31, 32, and 33. Thereby, the material can be prevented from leaking out between the pressing portions 47A, 47B, 47C and the material receiving portions 31, 32, and 33.

Meanwhile, a first magnetic body 392 may be disposed in the material receiving body 36, and a second magnetic body 393 acting as a repulsive force with the first magnetic body 392 may be disposed in the lid module 37.

The first magnetic body 392 may be positioned in front of the material receiving portions 31, 32, and 33, and the second magnetic body 393 may be positioned in front of the pressing portions 47A, 47B, and 47C. I can. When the lid module 37 is closed, the first magnetic body 392 and the second magnetic body 393 may face each other vertically.

At least one of the first magnetic body 392 and the second magnetic body 393 may include a magnet.

When the first magnetic body 392 and the second magnetic body 393 exert a repulsive force on each other, unlocking of the lid module 37 may be made easier. In addition, in the unlocked state, the gap g between the bottom surface 391 of the lid module 37 and the upper surface 39A of the material receiving body 36 can be easily maintained.

12 is a cross-sectional view showing that yeast and coating liquid are injected into a beverage material capsule. 13 is a cross-sectional view showing a mixture of yeast and coating liquid in a beverage material capsule.

Referring to Figure 12, the beverage material contained in the beverage material capsule (C1) (C2) (C3) includes a powder material (E) provided in a powder form and a coating solution (C) coating the powder material (E). I can.

The powdered material (E) is characterized in that it has a viscosity when in contact with water, for example, may be yeast. In addition, the coating liquid (C) may be defined as a liquid mixed with the powder material (E) but not mixed.

The coating solution (C) may be at least one of propylene glycol, hop oil, flavoring solution, ethylene, vegetable glycerin, edible oil, and alcohol. In addition, various liquids that are edible and not compatible with the powdered material (E) may be used as the coating liquid (C).

On the other hand, when the coating liquid (C) is hop oil or flavoring liquid, the number of beverage material capsules (C1) (C2) (C3) accommodated in the material feeder (3) may be reduced. In detail, when the coating liquid (C) is a hop oil and a flavor additive, yeast, hop oil, and flavor additive may be added to one beverage material capsule (C1) to be accommodated in the material feeder (3). Accordingly, the number of the beverage material capsules C1, C2, and C3 and the material receiving portions 31, 32 and 33 accommodated in the material feeder 3 can be reduced. Accordingly, the material feeder 3 can be downsized, and the beverage maker can be downsized.

For convenience of explanation, in the following description, a beverage material capsule and a material accommodated in the beverage material capsule will be described with a focus on the first beverage material capsule C1. However, this is not limited to the first beverage material capsule (C1), and the content described below may be applied to the second beverage material capsule (C2) or the third beverage material capsule (C3).

As described above, the first beverage material capsule C1 will be accommodated so that the cover joint CB2 is positioned downward. Accordingly, when the first beverage material capsule C1 is accommodated in the first material receiving portion 31, the beverage material may be located in a space below the capsule body CB. In this case, the amount into which the coating solution C is added, that is, the height L2 of the coating solution C may be equal to or slightly higher than the height L1 of the powder material E. In other words, it will be preferable that the coating solution (C) is filled to a height at which the powder material (E) is all immersed in the coating solution (C).

On the other hand, since the powder material E and the coating solution C are not mixed, when the first beverage material capsule C1 is mixed with motion, they may be mixed with each other and become a mixed state as shown in FIG. 13.

14 is a diagram showing a process in which a beverage material is extracted by supplying water to a beverage material capsule. In fact, in 14-(a) and 14-(b), the first beverage material capsule C1 is seated on the first material receiving part 31 and the capsule cover CC is cut off. Therefore, even if water W is not supplied, a part of the beverage material may be extracted through the outlet 31B. However, for convenience of explanation, it is assumed that beverage ingredients are not extracted in 14-(a) and 14-(b).

First, referring to FIG. 14-(a), after the first beverage material capsule C1 is accommodated in the first material receiving part 31, water W may be supplied in the additive input step S500. .

The water W may be supplied through the inlet 31A of the material receiving part 31. In addition, the water W may be supplied vertically upward from the lower side of the first beverage material capsule C1 along the hole 411 of the fluid supply part 41. In addition, the powder material E and a portion of the coating liquid C, which were under the first beverage material capsule C1, may flow together along the flow of the water W.

On the other hand, since the coating liquid (C) surrounds each of the powders of the powdered material (E) before the water (W) is supplied, contact between the water (W) and the powdered material (E) can be prevented. Accordingly, a phenomenon in which the powder material E is solidified in contact with the water W can be reduced.

In addition, even if the coating solution (C) is solidified by contacting the water (W) with some of the powder of the powder material (E), the remaining powder of the powder material (E) is wrapped in the coating solution (C), Clumping can be prevented from increasing in size.

Next, referring to Fig. 14-(b), the water (W) is continuously supplied until all beverage ingredients are extracted, and the water (W) supplied in the capsule body (CB) is the capsule body. It can flow along the space within (CB).

The powder material (E) and the coating solution (C) may be mixed with each other by the flow of the water (W). Therefore, the powder material (E), the coating liquid (C), and the water (W) may be mixed with each other until the water (W) is supplied and all beverage materials are extracted.

And, as the water (W) is continuously supplied, beverage material may be extracted through the outlet 31B. Beverage ingredients that remain unbrewed can be mixed with water. 14-(c) shows that the powder material (E), the coating liquid (C), and the water (W) are mixed with each other. With reference to this, the state of the beverage material remaining in the first beverage material capsule C1 and the state of the beverage material to be extracted will be described.

A part of the powder material (E) remaining in the upper first beverage material capsule (C1) without being extracted may be extracted according to the flow of the water (W) as a single powder is surrounded by the coating liquid (C). (S1). Accordingly, the powder material E may not be solidified without being in contact with the water W yet. However, as time passes, the water W may penetrate and come into contact with the powder material E, and the powder material E may be solidified.

In addition, the other part of the powder material E may be in a state in which solidification has proceeded (S2). The powder material E, which has undergone solidification, may have viscosity in a state in contact with water. However, due to the flow of the coating liquid (C) according to the supply of the water (W), it will not be easily adhered to the wall surface of the first beverage material capsule (C1).

Meanwhile, the size of the powder material E solidified by the coating solution C may not be larger than a certain level. It can be understood that this is because the extraction time proceeds faster than the time when the size of the solidified powder material E increases, and can be extracted before the size of the solidified powder material E increases.

In addition, the remaining part of the powder material E may be extracted according to the flow of the water W while a plurality of powders are grouped together and surrounded by the coating liquid C (S3).

In addition, beverage materials may be extracted in various forms similar to this, and the coating liquid (C) remains around the powder material (E), so that the powder material (E) in the first beverage material capsule (C1) There is an advantage that the extraction of is easily made.
