The liquid supply device and the beverage dispenser as described above have the following common problems. That is, if careless oxidation progresses in wine in a wine bottle or a beverage in a mixing case, the taste and aroma of the beverage deteriorate. In Patent Document 1, although the nitrogen gas of the nitrogen gas cylinder is supplied to the wine bottle by the gas supply tube to prevent the oxidation of wine, it is necessary to perform work such as replacement of the nitrogen gas cylinder on a regular basis. There was a problem that the management was troublesome and the liquid supply device became unusable during such work.

On the other hand, in the liquid supply device described in Patent Document 1, it is not preferable that the wine stored in the wine bottle is oxidized, but the wine poured into the wine glass by the wine supply tube is to some extent. It may be preferable for the oxidation to proceed to. In that case, it is necessary to transfer the wine in the wine glass to the decanter and then perform the decanter again, and there is a problem in convenience such that it takes time and effort until the wine is ready to drink.

The techniques described in the present specification have been completed based on the above circumstances, firstly for the purpose of facilitating management and suppressing oxidation of beverages, and secondly. The purpose is to improve the convenience of making beverages ready to drink.

(1) The beverage supply machine according to the technique described in the present specification has a beverage supply unit that supplies the beverage of the beverage source and a separation film that separates oxygen and nitrogen contained in the air, and before separation. A separation unit that produces at least nitrogen-enriched air having a higher nitrogen content than the air in the above, and a nitrogen-enriched air supply unit that is connected to the separation unit and supplies the nitrogen-enriched air to the beverage supply source. And.

In this way, the beverage of the beverage source is supplied by the beverage supply unit. At the separation part, at least nitrogen-enriched air is generated by separating nitrogen and oxygen contained in air by a separation membrane. The nitrogen-enriched air generated in the separation part has a higher nitrogen content and a lower oxygen content than the air before separation. Therefore, the nitrogen-enriched air is supplied to the beverage supply source by the nitrogen-enriched air supply unit, so that the beverage in the beverage supply source is less likely to be oxidized. If the oxidation of the beverage in the beverage supply source is suppressed, the taste and aroma of the beverage supplied by the beverage supply unit will be good. Here, nitrogen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation part, so that the nitrogen stored in the conventional nitrogen cylinder is used for drinking. Compared to the need to replace the nitrogen cylinder to suppress oxidation, it is easier to manage and the unusable period associated with the work is reduced, which is more convenient.

(2) Further, in the beverage supply machine, in addition to the above (1), the beverage supply unit supplies the beverage to the container, and the separation unit has a higher oxygen content than the air before separation. Is producing high oxygen-enriched air, and may be provided with an oxygen-enriched air supply unit connected to the separation unit to supply the oxygen-enriched air to the container. By doing so, in the separation portion, the nitrogen and oxygen contained in the air are separated by the separation membrane, so that oxygen-enriched air is generated in addition to the nitrogen-enriched air. The oxygen-enriched air generated in the separation section has a higher oxygen content and a lower nitrogen content than the air before separation. Therefore, when handling a type of beverage whose taste and aroma are enriched by oxidation, the oxygen-enriched air is supplied to the container by the oxygen-enriched air supply unit, so that the beverage in the container is oxidized. Can be promoted and the taste and aroma of the beverage can be enriched. Compared to the case where the beverage in the container is transferred and the decanter that promotes oxidation is separately performed, the beverage can be made ready to drink without taking time and effort, which is excellent in convenience. Moreover, both the nitrogen-enriched air and the oxygen-enriched air generated by the separation portion can be effectively used.

(3) In addition to the above (2), the beverage supply machine has an oxygen-enriched air supply unit interposed in the beverage supply adjusting unit and an oxygen-enriched air supply unit. The valve is provided with at least a beverage supply adjusting unit and a control unit connected to and controlling the oxygen-enriched air supply valve, and the control unit comprises the oxygen produced by the oxygen-enriched air supply unit. The beverage supply adjusting unit and the oxygen-enriched air supply valve may be controlled so that the supply of the enriched air is started prior to the supply of the beverage by the beverage supply unit. By doing so, the beverage supply adjusting unit is controlled by the control unit, so that the supply amount and the supply timing of the beverage from the beverage supply unit to the container are adjusted. By controlling the oxygen-enriched air supply valve by the control unit, the supply amount and supply timing of the oxygen-enriched air from the oxygen-enriched air supply unit to the container are adjusted. Then, the control unit controls the beverage supply adjustment unit and the oxygen-enriched air supply valve, so that the oxygen-enriched air supply by the oxygen-enriched air supply unit starts prior to the beverage supply by the beverage supply unit. Therefore, the beverage is supplied into the container in a state of being filled with oxygen-enriched air in advance. As a result, the oxidation of the beverage is efficiently promoted in the container, and the beverage can be made more speedy to drink.

(4) Further, in addition to the above (2) or (3) in the beverage supply machine, the oxygen-enriched air supply unit sprays the oxygen-enriched air on the beverage supplied to the container. It may be arranged at an angle with respect to the beverage supply unit so as to be. In this way, the oxygen-enriched air supplied from the oxygen-enriched air supply unit, which is tilted with respect to the beverage supply unit, is blown to the beverage supplied from the beverage supply unit to the container. Therefore, oxygen-enriched air is easily mixed with the beverage. As a result, the oxidation of the beverage is efficiently promoted, and the beverage can be made more speedy to drink.

(5) Further, in addition to any of the above (2) to (4), the beverage supply machine includes a container storage unit for accommodating the container, and the oxygen-enriched air supply unit is the container. The oxygen-enriched air may be supplied to the accommodating portion. By doing so, when the oxygen-enriched air is supplied to the container accommodating portion from the oxygen-enriched air supply portion, the oxygen-enriched air is also supplied to the container accommodated in the container accommodating portion. By filling the container accommodating portion accommodating the container with oxygen-enriched air, the oxygen-enriched air in the container can easily stay. As a result, the oxidation of the beverage by the oxygen-enriched air is more likely to be promoted than in the case where the oxygen-enriched air is supplied to the container in an environment open to the outside.

(6) Further, in addition to any of the above (2) to (5), the beverage supply unit may supply wine or sake as the beverage to the container. In this way, wine or sake, which is a beverage supplied to the container by the beverage supply unit, is promoted to oxidize by supplying oxygen-enriched air to the container by the oxygen-enriched air supply unit, and taste and taste. The scent will be rich. The beverage supply source is a bottle containing wine or sake, which is a beverage.

(7) In addition to the above (1), the beverage supply unit supplies the beverage to the container, and is connected to the separation unit to supply the nitrogen-enriched air to the container. A second nitrogen-enriched air supply unit may be provided. In this way, the nitrogen-enriched air generated in the separation unit is supplied to the beverage supply source by the nitrogen-enriched air supply unit and to the container by the second nitrogen-enriched air supply unit. Therefore, when handling a type of beverage whose taste and aroma are likely to deteriorate due to oxidation, the nitrogen-enriched air is supplied to the beverage supply source by the nitrogen-enriched air supply unit, so that the nitrogen-enriched air is in the beverage supply source. The oxidation of the beverage is suppressed, and the nitrogen-enriched air is supplied to the container by the second nitrogen-enriched air supply unit, so that the oxidation of the beverage in the container is suppressed, so that the taste and aroma of the beverage are further enhanced. It becomes difficult to deteriorate.

(8) Further, in addition to the above (7), the beverage feeder includes a mixing unit that mixes the raw material of the beverage and the liquid that dissolves the raw material to produce the beverage. The beverage source may be configured. In this way, in the mixing section constituting the beverage supply source, the raw material of the beverage and the liquid can be mixed and the raw material can be dissolved in the liquid to produce the beverage. Here, when the raw material and the liquid are mixed, the air existing in the surroundings is easily taken into the beverage, and there is a concern that the oxygen contained in the air dissolves in the beverage and promotes oxidation. In that respect, since nitrogen-enriched air is supplied to the mixing unit constituting the beverage supply source by the nitrogen-enriched air supply unit, it is difficult for oxygen to dissolve in the beverage when the raw material and the liquid are mixed. As a result, the beverage produced in the mixing portion is less likely to be oxidized. The beverage supplied from the mixing unit to the container by the beverage supply unit is exposed to the nitrogen-enriched air supplied to the container by the second nitrogen-enriched air supply unit. In this way, the beverage is continuously suppressed from oxidation by the nitrogen-enriched air from the time it is produced in the mixing portion until it is supplied to the container, so that the deterioration of taste and aroma is effectively suppressed. Will be done.

(9) Further, in addition to the above (8), the beverage supply machine adjusts the supply of the nitrogen-enriched air in at least one of the nitrogen-enriched air supply unit and the second nitrogen-enriched air supply unit. The nitrogen-enriched air supply valve is provided with at least a nitrogen-enriched air supply valve and a control unit connected to and controls the nitrogen-enriched air supply valve, and the control unit is the nitrogen-enriched air supply unit. The nitrogen-enriched air supply valve and the mixing unit may be controlled so that the supply of the nitrogen-enriched air by the above is started prior to the production of the beverage in the mixing unit. By doing so, the nitrogen-enriched air supply valve is controlled by the control unit, so that at least one of the nitrogen-enriched air supply unit and the second nitrogen-enriched air supply unit becomes at least one of the mixing unit and the container. The supply amount and supply timing of nitrogen-enriched air will be adjusted. By controlling the mixing unit by the control unit, the timing at which the beverage is produced and the time for mixing the raw material and the liquid are adjusted. Then, by controlling the nitrogen-enriched air supply valve and the mixing unit by the control unit, the supply of nitrogen-enriched air by the nitrogen-enriched air supply unit is started prior to the production of the beverage in the mixing unit. Therefore, the supply of the beverage to the container and the production of the beverage in the mixing portion are started with the inside of at least one of the container and the mixing portion filled with nitrogen-enriched air in advance. It will be. As a result, oxidation of the beverage is efficiently suppressed in at least one of the container and the mixing portion, and the taste and aroma of the beverage are less likely to deteriorate.

(10) Further, in the beverage feeder, in addition to any of the above (7) to (9), one end side is connected to the separation portion and the other end side is the nitrogen-enriched air supply portion and the second. A common nitrogen-enriched air supply unit may be provided that is connected to both of the nitrogen-enriched air supply units. In this way, the nitrogen-enriched air supply unit and the second nitrogen-enriched air supply unit are indirectly connected to the separation unit via the common nitrogen-enriched air supply unit. Therefore, the nitrogen-enriched air generated in the separation unit is distributed to the nitrogen-enriched air supply unit and the second nitrogen-enriched air supply unit via the common nitrogen-enriched air supply unit. Compared to the case where the nitrogen-enriched air supply unit and the second nitrogen-enriched air supply unit are individually connected to the separation unit, the configuration of the separation unit is simpler, so for example, a general-purpose product is used as the separation unit. Is possible.

(11) Further, in addition to any of the above (7) to (10), the beverage supply machine includes a container storage unit for accommodating the container, and the second nitrogen-enriched air supply unit is provided. , The nitrogen-enriched air may be supplied to the container accommodating portion. By doing so, when the nitrogen-enriched air is supplied to the container accommodating portion from the second nitrogen-enriched air supply portion, the nitrogen-enriched air is also supplied to the container accommodated in the container accommodating portion. .. By filling the container accommodating portion accommodating the container with the nitrogen-enriched air, the nitrogen-enriched air in the container can easily stay. As a result, the beverage in the container is less likely to be oxidized by the nitrogen-enriched air as compared with the case where the nitrogen-enriched air is supplied to the container in an environment open to the outside.

(12) Further, in addition to any of the above (7) to (11), the beverage feeder produces oxygen-enriched air having a higher oxygen content than the air before separation. An oxygen-enriched air discharge unit that is connected to the separation unit and discharges the oxygen-enriched air to the outside may be provided. By doing so, the oxidatively enriched air generated in the separation portion can be discharged to the outside by the oxygen enriched air discharge portion.

(13) The beverage supply machine according to the technique described in the present specification has a beverage supply unit that supplies the beverage to the container and a separation film that separates oxygen and nitrogen contained in the air, and the air before separation. It is provided with a separation unit that produces at least oxygen-enriched air having a higher oxygen content than the above, and an oxygen-enriched air supply unit that is connected to the separation unit and supplies the oxygen-enriched air to the container. ..

In this way, the beverage is supplied to the container by the beverage supply unit. At the separation part, at least oxygen-enriched air is generated by separating nitrogen and oxygen contained in air by a separation membrane. The oxygen-enriched air generated in the separation section has a higher oxygen content and a lower nitrogen content than the air before separation. Therefore, when handling a type of beverage whose taste and aroma are enriched by oxidation, the oxygen-enriched air is supplied to the container by the oxygen-enriched air supply unit, so that the beverage in the container is oxidized. Can be promoted and the taste and aroma of the beverage can be enriched. Compared to the case where the beverage in the container is transferred and the decanter that promotes oxidation is separately performed, the beverage can be made ready to drink without taking time and effort, which is excellent in convenience. Here, oxygen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation part, so that oxygen stored in the oxygen cylinder is used to promote the oxidation of the beverage. Compared to the need for work such as replacement of oxygen cylinders, it is easier to manage and the unusable period associated with the work is reduced, which is more convenient.

(14) Further, in the beverage supply machine, in addition to the above (13), the beverage supply unit supplies the beverage from the beverage supply source, and the separation unit is more nitrogen-based than the air before separation. A nitrogen-enriched air supply unit that produces nitrogen-enriched air having a high content and is connected to the separation unit to supply the nitrogen-enriched air to the beverage supply source may be provided. In this way, in the separation portion, nitrogen and oxygen contained in the air are separated by the separation membrane, so that nitrogen-enriched air is generated in addition to the oxygen-enriched air. The nitrogen-enriched air generated in the separation part has a higher nitrogen content and a lower oxygen content than the air before separation. Therefore, the nitrogen-enriched air is supplied to the beverage supply source by the nitrogen-enriched air supply unit, so that the beverage in the beverage supply source is less likely to be oxidized. If the oxidation of the beverage in the beverage supply source is suppressed, the taste and aroma of the beverage supplied by the beverage supply unit will be good. Moreover, both the nitrogen-enriched air and the oxygen-enriched air generated by the separation portion can be effectively used.

(15) Further, in addition to the above (13) or (14), the beverage supply machine is interposed in the beverage supply adjusting unit interposed in the beverage supply unit and the oxygen-enriched air supply unit. The oxygen-enriched air supply valve includes at least the beverage supply adjusting unit and a control unit connected to and controls the oxygen-enriched air supply valve, and the control unit comprises the oxygen-enriched air. The beverage supply adjusting unit and the oxygen-enriched air supply valve may be controlled so that the supply of the oxygen-enriched air by the supply unit is started prior to the supply of the beverage by the beverage supply unit. By doing so, the beverage supply adjusting unit is controlled by the control unit, so that the supply amount and the supply timing of the beverage from the beverage supply unit to the container are adjusted. By controlling the oxygen-enriched air supply valve by the control unit, the supply amount and supply timing of the oxygen-enriched air from the oxygen-enriched air supply unit to the container are adjusted. Then, the control unit controls the beverage supply adjustment unit and the oxygen-enriched air supply valve, so that the oxygen-enriched air supply by the oxygen-enriched air supply unit starts prior to the beverage supply by the beverage supply unit. Therefore, the beverage is supplied into the container in a state of being filled with oxygen-enriched air in advance. As a result, the oxidation of the beverage is efficiently promoted in the container, and the beverage can be made more speedy to drink.

(16) Further, the beverage feeder is added to any of the above (13) to (15), and the oxygen-enriched air supply unit is the oxygen-enriched beverage with respect to the beverage supplied to the container. It may be arranged at an angle with respect to the beverage supply unit so that air can be blown. In this way, the oxygen-enriched air supplied from the oxygen-enriched air supply unit, which is tilted with respect to the beverage supply unit, is blown to the beverage supplied from the beverage supply unit to the container. Therefore, oxygen-enriched air is easily mixed with the beverage. As a result, the oxidation of the beverage is efficiently promoted, and the beverage can be made more speedy to drink.

(17) Further, in addition to any of the above (13) to (16), the beverage supply machine includes a container storage unit for accommodating the container, and the oxygen-enriched air supply unit is the container. The oxygen-enriched air may be supplied to the accommodating portion. By doing so, when the oxygen-enriched air is supplied to the container accommodating portion from the oxygen-enriched air supply portion, the oxygen-enriched air is also supplied to the container accommodated in the container accommodating portion. By filling the container accommodating portion accommodating the container with oxygen-enriched air, the oxygen-enriched air in the container can easily stay. As a result, the oxidation of the beverage by the oxygen-enriched air is more likely to be promoted than in the case where the oxygen-enriched air is supplied to the container in an environment open to the outside.

According to the technique described in the present specification, firstly, oxidation of the beverage can be suppressed while facilitating management, and secondly, the convenience of making the beverage ready to drink is improved. be able to.

<Embodiment 1>
The first embodiment will be described with reference to FIG. In this embodiment, as an example of a beverage feeder, a wine dispenser 10 that supplies wine (beverage) W is shown.

As shown in FIG. 1, the wine dispenser 10 has a glass stage (container accommodating portion) 11 for accommodating a glass (container) G and a glass bottle (beverage supply source) B for accommodating wine W to wine in the glass G. A wine supply pipe (beverage supply unit) 12 for supplying W is provided at least. A plurality of bottles B (two bottles are exemplified in FIG. 1) are placed side by side in the bottle storage area. Further, the wine dispenser 10 is provided with an operation unit provided with an operation switch capable of allowing the user to perform a wine W pouring operation or the like.

The glass stage 11 has a substantially box shape, and a sufficient storage space for accommodating the glass G is secured inside the glass stage 11. A grill 11A on which the glass G is placed is laid on the bottom surface of the glass stage 11. An opening for taking in and out the glass G is provided on the front surface of the glass stage 11. It is possible to install an openable door at the opening of the glass stage 11, but it is also possible not to install such a door.

The wine supply pipe 12 is connected to the bottle B on one end side and to the glass stage 11 on the other end side. The wine supply pipe 12 has a bifurcated branch structure on one end side, and has two wine supply branch pipes (beverage supply branch portions) 12A. The two wine supply branch pipes 12A are inserted into the mouths of the two bottles B, respectively. A stopper B1 for keeping the inside of the bottle B airtight is press-fitted into the mouth of the bottle B, and the stopper B1 is provided with an opening for inserting the wine supply branch pipe 12A. A wine supply valve (beverage supply adjusting unit) 13 is interposed in each of the two wine supply branch pipes 12A in the wine supply pipe 12. The wine supply valve 13 can adjust the supply timing and supply amount of wine W in the wine supply branch pipe 12A according to the opening / closing timing and opening degree thereof. The other end side of the wine supply pipe 12 is introduced into the glass stage 11 through the pipe introduction opening 11B formed on the top surface of the glass stage 11. The other end of the wine supply pipe 12 is arranged so as to face the opening of the glass G placed on the grill 11A. Therefore, when the wine W is poured out from the spout port provided on the other end side of the wine supply pipe 12, the poured wine W is poured into the glass G. It should be noted that the two wine supply valves 13 can open only the other with one of them closed, but can also open both of them. For example, when the two wine supply valves 13 are opened together, the wine W is flowed from the two bottles B to the two wine supply branch pipes 12A, and at the common portion on the other end side of the wine supply pipe 12. After merging, it is supplied to the glass G.

Here, in the conventional wine dispenser, there is a problem that if careless oxidation of wine in a bottle progresses, the taste and aroma of the wine deteriorate, and the quality of the wine supplied to the glass is not good. .. On the other hand, although it is conceivable to prevent the oxidation of wine by supplying the nitrogen gas of the nitrogen gas cylinder to the wine bottle, it is necessary to perform work such as replacement of the nitrogen gas cylinder on a regular basis, which is troublesome to manage. There was a problem that the wine dispenser became unusable during such work.

On the other hand, although it is not preferable for the wine stored in the bottle to proceed with oxidation, it may be preferable for the wine poured into the glass to proceed with oxidation to some extent. For example, when handling red wines that have a strong astringency, a reducing odor, or a wine that has been bottled for a short period of time and has a closed aroma. In that case, it is necessary to transfer the wine in the glass to a decanter and then perform the decanter again, which causes a problem in convenience such as it takes time and effort until the wine is ready to drink.

Therefore, the wine dispenser 10 according to the present embodiment generates nitrogen-enriched air and oxygen-enriched air by separating oxygen and nitrogen from the air, and bottles B the nitrogen-enriched air and the oxygen-enriched air. And a distribution mechanism 20 for distributing to the glass stage 11. The distribution mechanism 20 includes a separation unit 21 including a separation film that separates oxygen and nitrogen from air, and an oxygen-enriched air supply pipe (oxygen-enriched air supply unit) that supplies oxygen-enriched air to the glass stage 11 and the glass G. ) 22, And at least a nitrogen-enriched air supply pipe (nitrogen-enriched air supply unit) 23 for supplying the nitrogen-enriched air to the bottle B. Further, the distribution mechanism 20 includes at least an air pump 24 having a suction port for taking in outside air, and a filter unit 25 for filtering the outside air taken in by the air pump 24 and supplying it to the separation unit 21.

According to the separation unit 21 and the nitrogen-enriched air supply pipe 23 provided in the distribution mechanism 20, the following actions and effects can be obtained. That is, the nitrogen-enriched air generated in the separation unit 21 is supplied to the bottle B by the nitrogen-enriched air supply pipe 23, so that the inside of the bottle B becomes a low oxygen environment. W is less likely to oxidize. If the oxidation of the wine W stored in the bottle B is suppressed, the taste and aroma of the wine W supplied to the glass G even if there is a time before the wine W is supplied by the wine supply pipe 12. Will be good. Here, since the nitrogen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation unit 21, the nitrogen stored in the conventional nitrogen cylinder is used for wine. Compared to the need for work such as replacement of a nitrogen cylinder to suppress the oxidation of W, it is easier to manage and the unusable period associated with the work is reduced, which is excellent in convenience.

On the other hand, according to the separation unit 21 and the oxygen-enriched air supply pipe 22 provided in the distribution mechanism 20, the following actions and effects can be obtained. That is, the oxygen-enriched air generated in the separation unit 21 is supplied to the glass G by the oxygen-enriched air supply pipe 22, so that the oxidation of the wine W poured into the glass G is promoted, and the wine W It can enrich the taste and aroma. For example, when handling red wine with strong astringency, when the oxidation of wine W is promoted by oxygen-enriched air, the polyphenols that cause astringency are reduced, and the astringency is alleviated. Further, when handling red wine having a reduced odor, the reduced odor is alleviated when the oxidation of the wine W is promoted by the oxygen-enriched air. Further, when handling red wine having a short period after being bottled and having a closed aroma, when the oxidation of the wine W is promoted by the oxygen-enriched air, the aroma is opened and the original flavor is obtained. In this way, compared to the case where the wine W of the glass G is transferred and the decanter that promotes oxidation is separately performed, it is convenient because the wine W can be made ready to drink without taking time and effort. Excellent for. Here, since the oxygen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation unit 21, the oxygen stored in the oxygen cylinder is used to oxidize the wine W. Compared to the need for work such as replacement of oxygen cylinders when promoting work, management is easier and the unusable period associated with the work is reduced, which is excellent in convenience. Then, both the nitrogen-enriched air and the oxygen-enriched air generated by the separation unit 21 can be effectively used. If only one of the nitrogen-enriched air and the oxygen-enriched air is used, it is necessary to exhaust the other, but according to the present embodiment, this necessity can be eliminated.

Subsequently, each configuration provided in the distribution mechanism 20 will be described in detail. The separation unit 21 has at least a separation membrane and a housing for accommodating the separation membrane. The separation membrane is a hollow fiber membrane made by bundling a large number of hollow fibers made of a polymer material, and has a property that oxygen and moisture can easily pass through, but nitrogen cannot easily pass through. Therefore, when air is passed through the separation membrane, oxygen and moisture contained in the air tend to easily permeate the separation membrane, whereas nitrogen contained in the air tends to be difficult to permeate the separation membrane. be. Utilizing such a property of the separation membrane, the separation unit 21 can separate oxygen and nitrogen from the air to generate nitrogen-enriched air and oxygen-enriched air. The nitrogen-enriched air has a higher nitrogen content (nitrogen concentration) and a lower oxygen content (oxygen concentration) than the air before separation. Oxygen-enriched air has a higher oxygen content and a lower nitrogen content than the air before separation. As the separation unit 21, for example, "SEPURUN (registered trademark) N2" manufactured by Daicel-Evonik Industries, Inc. can be used, but other products can also be used as appropriate. When the flow ratio of the generated nitrogen-enriched air to the oxygen-enriched air is "1: 1" using such a separation unit 21, the nitrogen content in the nitrogen-enriched air is, for example, about 93%. The oxygen content is about 6%, whereas the oxygen content in oxygen-enriched air is, for example, about 36% and the nitrogen content is about 63%. Generally, the content of nitrogen contained in the atmosphere is about 78%, and the content of oxygen contained in the atmosphere is about 21%. The air supplied to the separation unit 21 is the outside air taken in by the air pump 24, and is filtered by the filter unit 25 in advance to remove dust and the like contained in the outside air. As a result, problems such as clogging are less likely to occur in the separation membrane provided in the separation portion 21.

Of the oxygen-enriched air supply pipe 22 and the nitrogen-enriched air supply pipe 23 provided in the distribution mechanism 20, the nitrogen-enriched air supply pipe 23 will be described above. The nitrogen-enriched air supply pipe 23 is connected to the separation portion 21 on one end side and to the bottle B on the other end side. One end of the nitrogen-enriched air supply pipe 23 is connected to a portion of the separation portion 21 where nitrogen-enriched air is generated. The nitrogen-enriched air supply pipe 23 has a bifurcated branch structure on the other end side, and has two nitrogen-enriched air supply branch pipes (nitrogen-enriched air supply branch) 23A. The two nitrogen-enriched air supply branch pipes 23A are inserted into the openings formed in the respective plugs B1 press-fitted into the mouths of the two bottles B, respectively. The stopper B1 may be formed with two openings into which the wine supply branch pipe 12A and the nitrogen-enriched air supply pipe 23 are individually inserted, but the wine supply branch pipe 12A and the nitrogen-enriched air supply pipe are formed. One opening into which the 23 is inserted together may be formed.

A nitrogen-enriched air supply valve (nitrogen-enriched air supply valve) 26 is interposed in the nitrogen-enriched air supply pipe 23. The nitrogen-enriched air supply valve 26 is connected to a portion of the nitrogen-enriched air supply pipe 23 on the separation portion 21 side of the nitrogen-enriched air supply branch pipe 23A, that is, a common portion. The nitrogen-enriched air supply valve 26 can adjust the supply timing and supply amount of nitrogen-enriched air to the bottle B by adjusting the opening / closing timing and opening degree thereof. When the nitrogen-enriched air supply valve 26 is opened, the nitrogen-enriched air generated in the separation unit 21 is diverted from the common portion of the nitrogen-enriched air supply pipe 23 to the two nitrogen-enriched air supply valves 26. After that, it is supplied into each of the two bottles B.

Here, the inside of the bottle B to which the nitrogen-enriched air is supplied by the nitrogen-enriched air supply pipe 23 is a closed space by the stopper B1 that seals the mouth. Therefore, when the nitrogen-enriched air is supplied into the bottle B with the wine supply valve 13 open, the wine W in the bottle B can be pushed out into the wine supply pipe 12 by the pressure of the nitrogen-enriched air. As a result, the wine W can be poured into the glass G from the spout of the wine supply pipe 12. In this way, by supplying the nitrogen-enriched air into the bottle B by the nitrogen-enriched air supply pipe 23, the wine W is poured into the glass G while suppressing the oxidation of the wine W in the bottle B. Can be done. As a result, it is not necessary to separately prepare a dedicated device (pump, etc.) for pouring out the wine W.

Next, the oxygen-enriched air supply pipe 22 will be described. The oxygen-enriched air supply pipe 22 is connected to the separation portion 21 on one end side and to the glass stage 11 on the other end side. One end side of the oxygen-enriched air supply pipe 22 is connected to a portion of the separation portion 21 where oxygen-enriched air is generated. The other end side of the oxygen-enriched air supply pipe 22 is introduced into the glass stage 11 through the pipe introduction opening 11B formed on the top surface of the glass stage 11. The pipe introduction opening 11B may be one opening into which the wine supply pipe 12 and the oxygen-enriched air supply pipe 22 are both inserted, but the wine supply pipe 12 and the oxygen-enriched air supply pipe 22 are individually inserted. It may be two openings to be inserted. The other end side of the oxygen-enriched air supply pipe 22 is arranged so as to face the opening of the glass G placed on the grill 11A together with the other end side of the wine supply pipe 12. Therefore, when oxygen-enriched air is supplied from the supply port provided on the other end side of the oxygen-enriched air supply pipe 22, the inside of the glass G is filled with the supplied oxygen-enriched air and the glass surrounding the glass G is surrounded. The space inside the stage 11 is also filled. By filling the space in the glass stage 11 with the oxygen-enriched air in this way, the oxygen-enriched air in the glass G can easily stay. As a result, the oxidation of wine W by the oxygen-enriched air is more likely to be promoted than in the case where the oxygen-enriched air is supplied to the glass G in an environment open to the outside.

An oxygen-enriched air supply valve (oxygen-enriched air supply valve) 27 is interposed in the oxygen-enriched air supply pipe 22. The oxygen-enriched air supply valve 27 can adjust the supply timing and supply amount of oxygen-enriched air in the oxygen-enriched air supply pipe 22 by adjusting the opening / closing timing and opening degree thereof.

The wine dispenser 10 includes a control device (control unit, control box) 30. The control device 30 is connected to valves 13, 26, 27, an air pump 24, an operation unit, and the like. The control device 30 has a microcomputer, and the microcomputer includes a CPU, a memory, and the like, which are connected to each other via a bus. The control device 30 is supposed to control the operation of each valve 13, 26, 27 and the air pump 24 based on the operation input to the operation unit by the user. Besides that, the control device 30 can control the operation of each valve 13, 26, 27 and the air pump 24 based on the program stored in the memory. In this way, the operations of the valves 13, 26, 27 and the air pump 24 are appropriately controlled by the control device 30, so that the timing and amount of nitrogen-enriched air and oxygen-enriched air generated in the separation unit 21 and the like can be controlled. Is adjusted, the supply timing and supply amount of wine W to the glass G are adjusted, the supply timing and supply amount of nitrogen-enriched air to the bottle B are adjusted, and the oxygen richness to the glass G and the glass stage 11 is adjusted. The supply timing and supply amount of the converted air are adjusted.

In particular, the control device 30 has a wine supply valve 13 and oxygen-enriched air so that the supply of oxygen-enriched air by the oxygen-enriched air supply pipe 22 is started prior to the supply of wine W by the wine supply pipe 12. It controls the supply valve 27. Specifically, when the operation for starting the pouring of the wine W is input to the operation unit, the control device 30 drives the air pump 24 to drive the nitrogen-enriched air and the oxygen-enriched air in the separation unit 21. The oxygen-enriched air supply valve 27 is opened to supply the oxygen-enriched air to the glass stage 11, and the nitrogen-enriched air supply valve 26 is opened to supply the nitrogen-enriched air to the bottle B. When the oxygen-enriched air is supplied for a predetermined time and the internal space of the glass stage 11 (including the internal space of the glass G) is sufficiently filled with the oxygen-enriched air, the control device 30 is subsequently subjected to the control device 30. , The wine supply valve 13 is opened to supply the wine W to the glass G. In this way, the wine supply valve 13 and the oxygen-enriched air supply valve 27 are controlled by the control device 30, so that the glass G and the glass stage 11 are provided with the oxygen-enriched air supply pipe prior to the supply of the wine W. Since the supply of oxygen-enriched air is started by 22, the wine W is supplied with the inside of the glass G and the glass stage 11 filled with oxygen-enriched air in advance. As a result, the oxidation of the wine W is efficiently promoted in the glass G, so that the wine W can be made more speedy to drink.

As described above, the wine dispenser (beverage supply machine) 10 of the present embodiment is contained in the wine supply pipe (beverage supply unit) 12 for supplying the wine (beverage) W of the bottle (beverage supply source) B and the air. A separation unit 21 that has a separation film that separates oxygen and nitrogen and produces at least nitrogen-enriched air with a higher nitrogen content than the air before separation, and a nitrogen-enriched unit that is connected to the separation unit 21. A nitrogen-enriched air supply pipe (nitrogen-enriched air supply unit) 23 for supplying air to the bottle B is provided.

In this way, the wine W in the bottle B is supplied by the wine supply pipe 12. In the separation unit 21, at least nitrogen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation membrane. The nitrogen-enriched air generated in the separation unit 21 has a higher nitrogen content and a lower oxygen content than the air before separation. Therefore, the nitrogen-enriched air is supplied to the bottle B by the nitrogen-enriched air supply pipe 23, so that the wine W in the bottle B is less likely to be oxidized. If the oxidation of the wine W in the bottle B is suppressed, the taste and aroma of the wine W supplied by the wine supply pipe 12 will be good. Here, since the nitrogen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation unit 21, the nitrogen stored in the conventional nitrogen cylinder is used for wine. Compared to the need for work such as replacement of a nitrogen cylinder to suppress the oxidation of W, it is easier to manage and the unusable period associated with the work is reduced, which is excellent in convenience. As a result, it is possible to suppress the oxidation of wine W while facilitating management.

Further, the wine supply pipe 12 supplies the wine W to the glass (container) G, and the separation unit 21 generates oxygen-enriched air having a higher oxygen content than the air before separation, and is separated. An oxygen-enriched air supply pipe (oxygen-enriched air supply unit) 22 connected to a unit 21 and supplying oxygen-enriched air to the glass G is provided. In this way, the separation unit 21 separates nitrogen and oxygen contained in the air by the separation membrane, so that oxygen-enriched air is generated in addition to the nitrogen-enriched air. The oxygen-enriched air generated in the separation unit 21 has a higher oxygen content and a lower nitrogen content than the air before separation. Therefore, when handling a type of wine W whose taste and aroma are enriched by oxidation as a beverage, the oxygen-enriched air is supplied to the glass G by the oxygen-enriched air supply pipe 22 to the glass G. Oxidation of a certain wine W is promoted, and the taste and aroma of the wine W can be enriched. Compared to the case where the wine W of the glass G is transferred and the decanter that promotes oxidation is separately performed, the wine W can be made ready to drink without taking time and effort, which is excellent in convenience. Moreover, both the nitrogen-enriched air and the oxygen-enriched air generated by the separation unit 21 can be effectively used.

Further, a wine supply valve (beverage supply adjusting unit) 13 interposed in the wine supply pipe 12 and an oxygen enriched air supply valve (oxygen enriched air supply valve) 27 interposed in the oxygen enriched air supply pipe 22. And at least a control device (control unit) 30 connected to and controlling the wine supply valve 13 and the oxygen-enriched air supply valve 27, and the control device 30 is an oxygen-enriched air supply pipe 22. The wine supply valve 13 and the oxygen-enriched air supply valve 27 are controlled so that the supply of oxygen-enriched air is started prior to the supply of wine W by the wine supply pipe 12. By doing so, the wine supply valve 13 is controlled by the control device 30, and the supply timing and supply amount of the wine W from the wine supply pipe 12 to the glass G are adjusted. By controlling the oxygen-enriched air supply valve 27 by the control device 30, the supply timing and supply amount of the oxygen-enriched air from the oxygen-enriched air supply pipe 22 to the glass G are adjusted. Then, by controlling the wine supply valve 13 and the oxygen-enriched air supply valve 27 by the control device 30, the oxygen-enriched air is supplied by the oxygen-enriched air supply pipe 22 and the wine W is supplied by the wine supply pipe 12. Since it is started prior to the above, the wine W is supplied into the glass G in a state of being filled with oxygen-enriched air in advance. As a result, the oxidation of the wine W is efficiently promoted in the glass G, and the wine W can be made more speedy to drink.

Further, a glass stage (container accommodating portion) 11 for accommodating the glass G is provided, and the oxygen-enriched air supply pipe 22 supplies oxygen-enriched air to the glass stage 11. By doing so, when the oxygen-enriched air is supplied to the glass stage 11 from the oxygen-enriched air supply pipe 22, the oxygen-enriched air is also supplied to the glass G housed in the glass stage 11. By filling the glass stage 11 accommodating the glass G with the oxygen-enriched air, the oxygen-enriched air in the glass G can easily stay. As a result, the oxidation of wine W by the oxygen-enriched air is more likely to be promoted than in the case where the oxygen-enriched air is supplied to the glass G in an environment open to the outside.

Further, the wine supply pipe 12 supplies wine W to the glass G as a beverage. In this way, the wine W, which is a beverage supplied to the glass G by the wine supply pipe 12, is promoted to be oxidized by supplying the oxygen-enriched air to the glass G by the oxygen-enriched air supply pipe 22. , The taste and aroma will be rich.

<Embodiment 2>
The second embodiment will be described with reference to FIG. In the second embodiment, the arrangement of the oxygen-enriched air supply pipe 122 is changed from the first embodiment described above.

Further, the same reference numerals are used to the components having the same names as those in the above-described first embodiment, which appear in the description of the present embodiment, and the subscript "1" is added to the beginning thereof.

As shown in FIG. 2, in the oxygen-enriched air supply pipe 122 according to the present embodiment, the other end side introduced into the glass stage is tilted with respect to the other end side of the wine supply pipe 112 similarly introduced. It is arranged. In this way, the axes on the other ends of the oxygen-enriched air supply pipe 122 and the wine supply pipe 112 intersect each other, so that the oxygen-enriched air supply pipe 122 is supplied from the supply port provided on the other end side. The oxygen-enriched air is blown from the oblique side to the droplet L of the wine W discharged from the spout provided on the other end side of the wine supply pipe 112. As a result, oxygen-enriched air is easily mixed with the droplet L of the wine W poured out into the glass G, so that the oxidation of the wine W is efficiently promoted and the wine W is made more speedy to drink. Can be done. If the oxygen-enriched air supply pipe 122 and the wine supply pipe 112 are arranged so that the axes on the other ends of each intersect at a position higher than the wine W supply upper limit position in the glass G, the spout is outlet. Since the certainty that the oxygen-enriched air is blown to the droplet L of the wine W on the way from the wine W is increased, the oxygen is more easily dissolved in the droplet L of the wine W. The specific arrangement of the oxygen-enriched air supply pipe 122 and the wine supply pipe 112 can be appropriately changed in addition to the above.

As described above, according to the present embodiment, the oxygen-enriched air supply pipe 122 is tilted with respect to the wine supply pipe 112 so that the oxygen-enriched air is blown to the wine W supplied to the glass G. Will be distributed. In this way, with respect to the wine W supplied from the wine supply pipe 112 to the glass G, the oxygen-enriched air supplied from the oxygen-enriched air supply pipe 122 inclined with respect to the wine supply pipe 112 is supplied. Since it is sprayed, oxygen-enriched air is easily mixed with the wine W. As a result, the oxidation of the wine W is efficiently promoted, and the wine W can be made more speedy to drink.

It is provided with at least a mixing case (mixing unit, beverage supply source) 44 to be used. The mixing case 44 mixes the tea powder P supplied from the tea powder supply device 42 and the water WA supplied from the water supply pipe 43 to generate tea T, and the generated tea T is used in the cup C of the cup stage 41. Can be supplied. It can be said that the mixing case 44 is a source of tea T. The tea dispenser 40 is provided with an operation unit provided with an operation switch capable of allowing the user to perform a tea T pouring operation or the like.

The cup stage 41 has a substantially box shape, and a sufficient storage space for accommodating the cup C is secured inside the cup stage 41. A grill 41A on which the cup C is placed is laid on the bottom surface of the cup stage 41. An opening for inserting and removing the cup C is provided on the front surface of the cup stage 41. It is possible to install an openable door in the opening of the cup stage 41, but it is also possible not to install such a door.

The tea powder supply device 42 has a canister 42A for storing the tea powder P and a shooter 42B arranged on the lower side of the canister 42A. The canister 42A has a substantially box shape, and a discharge port communicating with the shooter 42B is provided on a part of the lower surface thereof. A screw device driven by a motor is provided in the lower part of the canister 42A, and it is possible to discharge the stored tea powder P from the discharge port in a fixed amount as the screw device is driven. .. The shooter 42B has a tubular shape extending in the vertical direction, and the opening on the upper end side communicates with the discharge port of the canister 42A, and the opening on the lower end side faces the input port formed on the top surface of the mixing case 44. It is arranged. According to the above configuration, when the screw device is driven in the canister 42A, the tea powder P stored in the canister 42A is discharged from the discharge port in a predetermined amount, and the released tea powder P passes through the shooter 42B. It is designed to be loaded into the slot of the mixing case 44.

One end of the water supply pipe 43 is connected to the water supply source of the water WA, and the other end of the water supply pipe 43 is connected to the mixing case 44. The water supply pipe 43 has a bifurcated structure on one end side, and has a hot water supply pipe 43A and a cold water supply pipe 43B. The hot water supply pipe 43A is connected to a hot water supply source which is a hot water supply source, and the cold water supply pipe 43B is connected to a cold water supply source which is a cold water supply source. A hot water supply valve 43A1 is interposed in the hot water supply pipe 43A, and the hot water supply timing and the supply amount can be adjusted according to the opening / closing timing and the opening / closing timing of the hot water supply valve 43A1. A chilled water supply valve 43B1 is interposed in the chilled water supply pipe 43B, and the chilled water supply timing and the supply amount can be adjusted according to the opening / closing timing and the opening / closing timing of the chilled water supply valve 43B1. The other end side of the water supply pipe 43 is introduced into the mixing case 44 through the water supply pipe introduction opening 44C formed on the top surface of the mixing case 44. According to the above configuration, when at least one of the hot water supply valve 43A1 and the cold water supply valve 43B1 is opened, water WA is supplied into the mixing case 44 from the other end side of the water supply pipe 43. It should be noted that the hot water supply valve 43A1 and the cold water supply valve 43B1 can be opened only with the other closed, but both can be opened together. For example, when both the hot water supply valve 43A1 and the cold water supply valve 43B1 are opened, the hot water supplied by the hot water supply pipe 43A and the cold water supplied by the cold water supply pipe 43B merge in the middle of the water supply pipe 43. After that, it is supplied to the mixing case 44. Therefore, by adjusting each opening degree of the hot water supply valve 43A1 and the cold water supply valve 43B1, the temperature of the water WA supplied to the mixing case 44 can be adjusted.

The mixing case 44 has a substantially box shape, and a stirring blade 44A is provided on the bottom surface thereof. On the outside of the bottom of the mixing case 44, a stirring motor 44B for driving the stirring blade 44A to rotate is provided. When the stirring blade 44A is rotated by the stirring motor 44B with the tea powder P and the water WA charged in the mixing case 44, the tea powder P and the water WA are mixed and stirred to make tea. The dissolution of the powder P in the water WA is promoted, and the tea T is produced. On the top surface of the mixing case 44, at least a charging port into which the tea powder P supplied from the shooter 42B is charged and a water supply pipe introduction opening 44C into which the water supply pipe 43 is introduced are provided.

At the bottom of the mixing case 44, a tea supply pipe (beverage supply unit) 45 for supplying the generated tea T to the cup C of the cup stage 41 is provided. The tea supply pipe 45 extends downward from the bottom of the mixing case 44, and the extending end thereof is introduced into the cup stage 41 through the pipe introduction opening 41B formed on the top surface of the cup stage 41. The extending end side of the tea supply pipe 45 is arranged so as to face the opening of the cup C placed on the grill 41A. Therefore, when the tea T is poured out from the spout port provided on the extension end side of the tea supply pipe 45, the poured tea T is poured into the cup C.

Here, in the conventional tea dispenser, if the tea in the mixing case is inadvertently oxidized, the taste and aroma of the tea deteriorate, and the quality of the tea supplied to the cup is not good. there were. On the other hand, although it is conceivable to prevent the oxidation of tea by supplying the nitrogen gas of the nitrogen gas cylinder to the mixing case, it is necessary to perform work such as replacement of the nitrogen gas cylinder on a regular basis, which is troublesome to manage. During such work, there was a problem that the tea dispenser became unusable.

Therefore, the tea dispenser 40 according to the present embodiment generates nitrogen-enriched air and oxygen-enriched air by separating oxygen and nitrogen from the air, and puts the nitrogen-enriched air into at least the mixing case 44. A distribution mechanism 220 for distributing oxygen-enriched air to the outside (outside) of the device is provided. The distribution mechanism 220 comprises a separation unit 221 including a separation film that separates oxygen and nitrogen from air, a nitrogen-enriched air supply pipe 223 that supplies nitrogen-enriched air to at least the mixing case 44, and oxygen-enriched air. It is provided with at least an oxygen-enriched air discharge pipe (oxygen-enriched air discharge unit) 46 for discharging to the outside. Further, the distribution mechanism 220 includes at least an air pump 224 having a suction port for taking in outside air, and a filter unit 225 that filters the outside air taken in by the air pump 224 and supplies it to the separation unit 221.

The nitrogen-enriched air supply pipe 223 will be described in detail. The nitrogen-enriched air supply pipe 223 is connected to the separation unit 221 on one end side and to the mixing case 44 and the cup stage 41 on the other end side, respectively, and the nitrogen-enriched air generated by the separation unit 221 is mixed with the mixing case 44. And can be supplied to the cup stage 41, respectively. The nitrogen-enriched air supply pipe 223 has a bifurcated structure on the other end side, and has a first nitrogen-enriched air supply pipe (nitrogen-enriched air supply unit) 47 and a second nitrogen-enriched air supply pipe (second nitrogen-enriched air supply pipe). It has a second nitrogen-enriched air supply unit) 48. The first nitrogen-enriched air supply pipe 47 is introduced into the mixing case 44 through the first nitrogen-enriched air supply pipe introduction opening 44D formed on the top surface of the mixing case 44. The second nitrogen-enriched air supply pipe 48 is introduced into the cup stage 41 through the pipe introduction opening 41B formed on the top surface of the cup stage 41. The second nitrogen-enriched air supply pipe 48, together with the tea supply pipe 45, is arranged so as to face the opening of the cup C placed on the grill 41A. The pipe introduction opening 41B may be one opening into which both the tea supply pipe 45 and the second nitrogen-enriched air supply pipe 48 are inserted, but the tea supply pipe 45 and the second nitrogen-enriched air supply pipe are inserted. There may be two openings into which the 48 are inserted individually. Further, the nitrogen-enriched air supply pipe 223 has a common nitrogen-enriched air supply pipe (common nitrogen) connected to both the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48 on one end side. It has an enriched air supply unit) 49. In the nitrogen-enriched air supply pipe 223, the common nitrogen-enriched air supply pipe 49 on one end side is connected to the portion of the separation portion 221 where oxygen-enriched air is generated. The nitrogen-enriched air generated in the separation unit 221 is distributed from the common nitrogen-enriched air supply pipe 49 to the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48, and then the mixing case. It is designed to be supplied to each of the 44 and the cup stage 41. The distribution ratio of the nitrogen-enriched air in the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48 is the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48. It depends on the ratio of each diameter dimension (cross-sectional area of the internal space). The diameter dimensions of the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48 may be the same, but may be different from each other.

According to the separation unit 221 and the first nitrogen-enriched air supply pipe 47 provided in the distribution mechanism 220, the following actions and effects can be obtained. That is, the nitrogen-enriched air generated in the separation unit 221 is supplied to the mixing case 44 by the first nitrogen-enriched air supply pipe 47, so that the tea T in the mixing case 44 is less likely to be oxidized. In particular, in the mixing case 44, the tea powder P and the water WA are mixed by rotating the stirring blade 44A. At the time of mixing, the surrounding air is easily taken into the tea T, and the oxygen contained in the air is easily taken into the tea T. There is a concern that it will dissolve in tea T and promote oxidation. In that respect, since the nitrogen-enriched air is supplied to the mixing case 44 by the first nitrogen-enriched air supply pipe 47, the inside of the mixing case 44 becomes a low oxygen environment. Therefore, the stirring blade 44A is rotated to rotate the tea powder P. When mixing water WA with water, oxygen is difficult to dissolve in tea T. As a result, the tea T produced in the mixing case 44 is less likely to be oxidized, and the deterioration of the taste and aroma of the tea T with the passage of time is suppressed. Here, nitrogen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation unit 221. Therefore, tea is used using nitrogen stored in a conventional nitrogen cylinder. Compared to the need for work such as replacement of a nitrogen cylinder to suppress the oxidation of T, it is easier to manage and the unusable period associated with the work is reduced, which is excellent in convenience.

On the other hand, according to the separation unit 221 and the second nitrogen-enriched air supply pipe 48 provided in the distribution mechanism 220, the following actions and effects can be obtained. That is, the nitrogen-enriched air generated in the separation unit 221 is supplied to the cup stage 41 by the second nitrogen-enriched air supply pipe 48, so that the inside of the cup C is filled with the supplied nitrogen-enriched air. The space inside the cup stage 41 that surrounds the cup C is also filled. By filling the space in the cup stage 41 with the nitrogen-enriched air in this way, the nitrogen-enriched air in the cup C is likely to stay. As a result, the oxidation of tea T is suitably suppressed by the nitrogen-enriched air, as compared with the case where the nitrogen-enriched air is supplied to the cup C in an environment open to the outside. As described above, since the oxidation of tea T is continuously suppressed by the nitrogen-enriched air from the time it is produced in the mixing case 44 until it is supplied to the cup C, the taste and aroma are deteriorated. Effectively suppressed.

Further, the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48 are indirectly connected to the separation unit 221 via the common nitrogen-enriched air supply pipe 49. Therefore, the nitrogen-enriched air generated in the separation unit 221 is distributed to the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48 via the common nitrogen-enriched air supply pipe 49. It will be. Compared to the case where the first nitrogen-enriched air supply pipe and the second nitrogen-enriched air supply pipe are individually connected to the separation unit 221, one common nitrogen-enriched air supply pipe 49 to the separation unit 221. Along with this, the configuration of the separation unit 221 becomes simple, so that a general-purpose product can be used, for example, as the separation unit 221.

A common nitrogen-enriched air supply valve (nitrogen-enriched air supply valve and a second nitrogen-enriched air supply valve) 50 is interposed in the common nitrogen-enriched air supply pipe 49 constituting the nitrogen-enriched air supply pipe 223. Has been done. The common nitrogen-enriched air supply valve 50 is arranged near the end of the common nitrogen-enriched air supply pipe 49 on the separation portion 221 side. The common nitrogen-enriched air supply valve 50 adjusts its opening / closing timing and opening degree to adjust the distribution timing and distribution amount to the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48. It can be adjusted, and the timing and amount of nitrogen-enriched air supplied to the mixing case 44 and the cup stage 41 can be adjusted. When the common nitrogen-enriched air supply valve 50 is opened, the nitrogen-enriched air generated in the separation unit 221 is released from the common nitrogen-enriched air supply pipe 49 to the first nitrogen-enriched air supply pipe 47 and the second nitrogen-rich air. After being diverted to the chemical air supply pipe 48, it is supplied into the mixing case 44 and the cup stage 41, respectively.

The detailed configuration of the separation unit 221 is as described in the above-described first embodiment, and the separation membrane separates oxygen and nitrogen from the air to generate nitrogen-enriched air and oxygen-enriched air. Can be done. The air supplied to the separation unit 221 is the outside air taken in by the air pump 224, and is filtered by the filter unit 225 in advance to remove dust and the like contained in the outside air. As a result, problems such as clogging are less likely to occur in the separation membrane provided in the separation portion 221.

The oxygen-enriched air discharge pipe 46 provided in the distribution mechanism 220 is connected to the separation portion 221 on one end side, while the other end side is led out to the outside of the device. One end of the oxygen-enriched air discharge pipe 46 is connected to a portion of the separation portion 221 where oxygen-enriched air is generated. The other end of the oxygen-enriched air discharge pipe 46 penetrates the exterior of the tea dispenser 40 and is exposed to the outside of the device. As a result, the oxidatively enriched air generated as the nitrogen-enriched air is generated in the separation unit 221 is discharged to the outside of the device through the oxygen-enriched air discharge pipe 46. Further, the oxygen-enriched air discharge pipe 46 is interposed with an oxygen-enriched air discharge amount adjusting valve 51 for adjusting the amount of oxygen-enriched air discharged.

The tea dispenser 40 includes a control device (control unit, control box) 230. The control device 230 is connected to each valve 43A1, 43B1, 50, 51, an air pump 224, a stirring motor 44B, a screw device and its motor, an operation unit, and the like. The control device 230 has a microcomputer, and the microcomputer includes a CPU, a memory, and the like, which are connected to each other via a bus. The control device 230 is supposed to control the operation of each valve 43A1, 43B1, 50, 51, the air pump 224, the stirring motor 44B, and the screw device and its motor based on the operation input to the operation unit by the user. .. In addition, the control device 230 can control the operation of the valves 43A1, 43B1, 50, 51, the air pump 224, the stirring motor 44B, and the screw device and its motor based on the program stored in the memory. It is said that. In this way, the operations of the valves 43A1, 43B1, 50, 51, the air pump 224, the stirring motor 44B, and the screw device and its motor are appropriately controlled by the control device 230, thereby enriching the nitrogen in the separation unit 221. The timing and amount of oxygen-enriched air generated are adjusted, the timing and amount of nitrogen-enriched air supplied to the mixing case 44 and cup stage 41 are adjusted, and the oxygen-enriched air outside the device is adjusted. The discharge timing and discharge amount are adjusted, the supply timing and supply amount of water WA to the mixing case 44 are adjusted, and the ON / OFF timing (rotation time) and rotation speed of the rotation of the stirring blade 44A in the mixing case 44 are adjusted. Etc. are adjusted so that the ON / OFF timing (rotation time) and the rotation speed of the rotation of the screw device in the canister 42A are adjusted.

In particular, the control device 230 has a common nitrogen-enriched air supply valve so that the supply of nitrogen-enriched air by the first nitrogen-enriched air supply pipe 47 is started prior to the production of tea T in the mixing case 44. It controls 50 and the mixing case 44. Specifically, when the operation for starting the pouring of tea T is input to the operation unit, the control device 230 drives the air pump 224 to drive the nitrogen-enriched air and the oxygen-enriched air in the separation unit 221. The common nitrogen-enriched air supply valve 50 is opened to supply nitrogen-enriched air to the mixing case 44 and the cup stage 41. When the nitrogen-enriched air is supplied for a predetermined time and the internal spaces of the mixing case 44 and the cup stage 41 (including the internal space of the cup C) are sufficiently filled with the nitrogen-enriched air, the process is continued. The control device 230 rotates the screw device of the canister 42A to charge a predetermined amount of tea powder P into the mixing case 44, and supplies water WA from the water supply pipe 43 into the mixing case 44. Then, the control device 230 rotates the stirring blade 44A of the mixing case 44 for a predetermined time to dissolve the tea powder P in water WA to generate tea T, and the produced tea T is used in the cup stage 41. Pour into cup C. In this way, the common nitrogen-enriched air supply valve 50 and the mixing case 44 are controlled by the control device 230, so that the mixing case 44 and the cup stage 41 are nitrogen-enriched by the first nitrogen-enriched air supply pipe 47. Since the supply of air is started prior to the production of tea T in the mixing case 44, the cup is filled with nitrogen-enriched air in advance inside the mixing case 44 and the cup stage 41. The supply of tea T to C and the production of tea T in the mixing case 44 are started. As a result, the oxidation of tea T is efficiently suppressed in each of the cup C and the mixing case 44, and the taste and aroma of tea T are less likely to deteriorate.

As described above, the tea supply machine (beverage supply machine) 40 according to the present embodiment includes a tea supply pipe (beverage supply unit) 45 for supplying tea (beverage) T of the mixing case 44, which is a beverage supply source, and air. It is connected to the separation part 221 and the separation part 221 which have a separation film for separating oxygen and nitrogen contained in the above and generate at least nitrogen-enriched air having a higher nitrogen content than the air before separation. A first nitrogen-enriched air supply pipe (nitrogen-enriched air supply unit) 47 for supplying nitrogen-enriched air to the mixing case 44 is provided.

In this way, the tea T of the mixing case 44 is supplied by the tea supply pipe 45. In the separation unit 221, at least nitrogen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation membrane. The nitrogen-enriched air generated in the separation unit 221 has a higher nitrogen content and a lower oxygen content than the air before separation. Therefore, the nitrogen-enriched air is supplied to the mixing case 44 by the first nitrogen-enriched air supply pipe 47, so that the tea T in the mixing case 44 is less likely to be oxidized. If the oxidation of the tea T in the mixing case 44 is suppressed, the taste and aroma of the tea T supplied by the tea supply pipe 45 will be good. Here, nitrogen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation unit 221. Therefore, tea is used using nitrogen stored in a conventional nitrogen cylinder. Compared to the need for work such as replacement of a nitrogen cylinder to suppress the oxidation of T, it is easier to manage and the unusable period associated with the work is reduced, which is excellent in convenience. As a result, it is possible to suppress the oxidation of tea T while facilitating management.

Further, the tea supply pipe (beverage supply unit) 45 supplies tea (beverage) T to the cup (container) C, and is connected to the separation unit 221 to supply nitrogen-enriched air to the cup C. A nitrogen-enriched air supply pipe (second nitrogen-enriched air supply unit) 48 is provided. In this way, the nitrogen-enriched air generated in the separation unit 221 is supplied to the mixing case 44, which is a beverage supply source, by the first nitrogen-enriched air supply pipe 47, and the second nitrogen-enriched air is supplied. It is supplied to the cup C by the tube 48. Therefore, when handling a type of tea T whose taste and aroma tend to deteriorate due to oxidation as a beverage, the nitrogen-enriched air is supplied to the beverage supply source by the first nitrogen-enriched air supply pipe 47, so that the beverage is beverageed. Oxidation of the tea T in the mixing case 44, which is the supply source, is suppressed, and the nitrogen-enriched air is supplied to the cup C by the second nitrogen-enriched air supply pipe 48, so that the tea T in the cup C is oxidized. Is suppressed, so that the taste and aroma of tea T are less likely to deteriorate.

Further, it is provided with a mixing case (mixing unit) 44 for producing tea T by mixing tea powder (raw material) P, which is a raw material of tea T, and water (liquid) WA, which is a liquid that dissolves tea powder P. The mixing case 44 constitutes a beverage supply source. In this way, in the mixing case 44 constituting the beverage supply source, the tea T can be produced by mixing the tea powder P of the tea T and the water WA and dissolving the tea powder P in the water WA. Here, when the tea powder P and the water WA are mixed, the air existing in the surroundings is easily taken into the tea T, and the oxygen contained in the air dissolves in the tea T to promote oxidation. I am concerned. In that respect, since nitrogen-enriched air is supplied to the mixing case 44 constituting the beverage supply source by the first nitrogen-enriched air supply pipe 47, oxygen is tea when the tea powder P and water WA are mixed. It is difficult to blend in with T. As a result, the tea T produced in the mixing case 44 is less likely to be oxidized. The tea T supplied from the mixing case 44 to the cup C by the tea supply pipe 45 is exposed to the nitrogen-enriched air supplied to the cup C by the second nitrogen-enriched air supply pipe 48. As described above, since the oxidation of tea T is continuously suppressed by the nitrogen-enriched air from the time it is produced in the mixing case 44 until it is supplied to the cup C, deterioration of taste and aroma is effective. Is suppressed.

Further, a common nitrogen-enriched air supply valve (nitrogen-enriched air supply valve) 50 that regulates the supply of nitrogen-enriched air in at least one of the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48. And at least a control device 230 connected to and controlling a common nitrogen-enriched air supply valve 50 and a mixing case 44, and the control device 230 is provided with nitrogen by a first nitrogen-enriched air supply pipe 47. The common nitrogen-enriched air supply valve 50 and the mixing case 44 are controlled so that the supply of enriched air is started prior to the production of tea T in the mixing case 44. By doing so, the common nitrogen-enriched air supply valve 50 is controlled by the control device 230, so that the mixing case can be taken from at least one of the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48. The supply timing and supply amount of nitrogen-enriched air to at least one of 44 and the cup C are adjusted. By controlling the mixing case 44 by the control device 230, the timing at which the tea T is produced, the time for mixing the tea powder P and the water WA, and the like are adjusted. Then, by controlling the common nitrogen-enriched air supply valve 50 and the mixing case 44 by the control device 230, the supply of nitrogen-enriched air by the first nitrogen-enriched air supply pipe 47 becomes the tea T in the mixing case 44. The tea T is supplied and mixed to the cup C with the inside of at least one of the cup C and the mixing case 44 filled with nitrogen-enriched air in advance. At least one of the production of tea T in case 44 will be initiated. As a result, the oxidation of tea T is efficiently suppressed in at least one of the cup C and the mixing case 44, and the taste and aroma of tea T are less likely to deteriorate.

Further, a common nitrogen-enriched air supply pipe (common nitrogen-rich) in which one end side is connected to the separation portion 221 and the other end side is connected to both the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48. (Chemical air supply unit) 49 is provided. In this way, the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48 are indirectly connected to the separation unit 221 via the common nitrogen-enriched air supply pipe 49. .. Therefore, the nitrogen-enriched air generated in the separation unit 221 is distributed to the first nitrogen-enriched air supply pipe 47 and the second nitrogen-enriched air supply pipe 48 via the common nitrogen-enriched air supply pipe 49. It will be. Compared to the case where the first nitrogen-enriched air supply pipe and the second nitrogen-enriched air supply pipe are individually connected to the separation unit 221, the configuration of the separation unit 221 is simpler. It is possible to use general-purpose products.

Further, a cup stage (container accommodating portion) 41 for accommodating the cup C is provided, and the second nitrogen-enriched air supply pipe 48 supplies nitrogen-enriched air to the cup stage 41. By doing so, when the nitrogen-enriched air is supplied to the cup stage 41 from the second nitrogen-enriched air supply pipe 48, the nitrogen-enriched air is also supplied to the cup C housed in the cup stage 41. To. By filling the cup stage 41 accommodating the cup C with the nitrogen-enriched air, the nitrogen-enriched air in the cup C can easily stay. As a result, the tea T in the cup C is less likely to be oxidized by the nitrogen-enriched air as compared with the case where the nitrogen-enriched air is supplied to the cup C in an environment open to the outside.

Further, the separation unit 221 generates oxygen-enriched air having a higher oxygen content than the air before separation, and is connected to the separation unit 221 to discharge the oxygen-enriched air to the outside. A discharge pipe (oxygen-enriched air discharge unit) 46 is provided.

The other end of the nitrogen-enriched air discharge pipe 28 penetrates the exterior of the wine dispenser 310 and is exposed to the outside of the device. As a result, the nitrogen-enriched air generated as the oxygen-enriched air is generated in the separation unit 321 is discharged to the outside of the device through the nitrogen-enriched air discharge pipe 28. Further, the nitrogen-enriched air discharge pipe 28 is interposed with a nitrogen-enriched air discharge amount adjusting valve 29 for adjusting the exhaust amount of the nitrogen-enriched air and the like.

The oxygen-enriched air generated by the separation unit 321 has a higher oxygen content and a lower nitrogen content than the air before separation. Therefore, when handling a type of tea T whose taste and aroma are enriched by oxidation as a beverage, the oxygen-enriched air is supplied to the glass G by the oxygen-enriched air supply pipe 322, so that the glass G is supplied with oxygen-enriched air. Oxidation of a certain wine W is promoted, and the taste and aroma of the wine W can be enriched. Compared to the case where the wine W of the glass G is transferred and the decanter that promotes oxidation is separately performed, the wine W can be made ready to drink without taking time and effort, which is excellent in convenience. Here, the oxygen-enriched air is generated by separating nitrogen and oxygen contained in the air by the separation film of the separation unit 321. Therefore, the oxygen stored in the oxygen cylinder is used to oxidize the wine W. Compared to the need for work such as replacement of oxygen cylinders when promoting work, management is easier and the unusable period associated with the work is reduced, which is excellent in convenience. According to this embodiment, it is possible to improve the convenience of making wine W ready to drink.
