  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected about the same or equivalent element, and the description is abbreviate | omitted when description overlaps.

  FIG. 1 shows an overall configuration of a beverage providing apparatus 1 for providing a grain-based sparkling beverage provided with a currant 10 according to the embodiment. Here, the cereal sparkling beverage is a sparkling beverage made from cereals such as beer and sparkling liquor. Examples of the cereal include a group consisting of barley, wheat, rice, corn, beans and potatoes. 1 type or more selected from more is contained. The grain-type sparkling beverage includes alcoholic beverages as well as beverages that do not contain alcohol. Below, it demonstrates as what provides beer as a grain-type sparkling beverage.

  The beverage providing device 1 is provided in a restaurant, for example, and is a device that dispenses beer from the currant 10 in accordance with a customer order or the like. First, the whole structure of the drink provision apparatus 1 is demonstrated. The beverage providing device 1 includes a carbon dioxide cylinder 2, a pressure reducing valve 3, a carbon dioxide hose 4, a beer barrel 5, a head 6, a beer hose 7, a server 8, and a cooling device 9 in addition to the currant 10. ing.

  The carbon dioxide cylinder 2 is a substantially cylindrical container filled with carbon dioxide at a high pressure. The carbon dioxide cylinder 2 has a function of pushing out the beer liquid inside the beer barrel 5 to the server 8 and also has a function of keeping the amount of carbon dioxide contained in the beer liquid inside the beer barrel 5 at an appropriate amount. Inside the carbon dioxide cylinder 2, the carbon dioxide is filled in a liquid state, for example, at a pressure of about 6 to 8 MPa. The carbon dioxide gas cylinder 2 includes a remaining amount indicator 2 a that displays the amount of carbon dioxide gas inside the carbon dioxide gas cylinder 2. As the remaining amount indicator 2a, for example, a needle-shaped one can be used. In this case, when the needle is pointing upward, the amount of carbon dioxide in the carbon dioxide cylinder 2 is relatively large, When the needle is pointing downward, it indicates that the amount of carbon dioxide in the carbon dioxide cylinder 2 has decreased. Thus, the carbon dioxide gas cylinder 2 is provided with the remaining amount indicator 2a, so that the amount of carbon dioxide gas in the carbon dioxide gas cylinder 2 can be visually recognized. The carbon dioxide gas cylinder 2 is provided with an opening / closing handle (not shown) that can be rotated by a user at the upper part of the carbon dioxide gas cylinder 2. Can be opened and closed.

  The pressure reducing valve 3 is a device for adjusting the pressure (hereinafter referred to as gas pressure) due to carbon dioxide applied to the beer liquid inside the beer barrel 5. The pressure reducing valve 3 includes a residual pressure indicator 3 a that displays the residual pressure of the carbon dioxide gas in the carbon dioxide cylinder 2 and a rotary operation unit 3 b for adjusting the gas pressure. For example, the user can increase the gas pressure by rotating the operation unit 3b in the clockwise direction and can decrease the gas pressure by rotating the operation unit 3b in the counterclockwise direction. Here, the amount of carbon dioxide dissolved in the liquid decreases as the temperature of the liquid increases, and increases as the temperature of the liquid decreases. Therefore, by adjusting the gas pressure to an appropriate value with the pressure reducing valve 3 in accordance with the temperature of the beer liquid in the beer barrel 5, gas separation in which carbon dioxide gas escapes from the beer liquid at a high temperature, or the beer liquid generates carbon dioxide at a low temperature. It is possible to prevent oversaturation that is excessively absorbed.

  The beer barrel 5 is a container filled with beer liquid. Since the inside of the beer barrel 5 is hermetically sealed, various germs and the like are prevented from entering the inside of the beer barrel 5. Further, for example, a card-like liquid temperature detection unit 5a can be attached to the surface of the beer barrel 5, and the temperature of the beer in the beer barrel 5 can be detected by the liquid temperature detection unit 5a. it can. In addition to the temperature of the beer in the beer barrel 5, the liquid temperature detector 5a displays the optimum value of the gas pressure corresponding to the detected temperature of the beer. Therefore, the user can adjust the gas pressure in the beer barrel 5 to an optimum value by operating the operation unit 3b of the pressure reducing valve 3 and setting the gas pressure to the value displayed on the liquid temperature detection unit 5a. It has become. The beer barrel 5 includes a tube 5b through which beer flows and a base (also referred to as a fitting valve) 5c. The tube 5b of the beer barrel 5 extends vertically inside the beer barrel 5, and the cap 5c is provided at the upper end of the tube 5b.

  The head 6 has a function of sending the carbon dioxide in the carbon dioxide cylinder 2 into the beer barrel 5 through the pressure reducing valve 3 and the carbon dioxide hose 4 and sending out the beer liquid in the beer barrel 5 to the server 8. The head 6 has an operation handle 6a capable of opening and closing a flow path of carbon dioxide gas and beer liquid by moving up and down, a gas joint 6b connected to the carbon dioxide hose 4, and a beer joint 6c connected to the beer hose 7. It has. The lower part of the head 6 is connected to the base 5c of the beer barrel 5, and the carbon dioxide hose 4 and the beer hose are lowered by lowering the operation handle 6a of the head 6 with the lower part of the head 6 connected to the base 5c. 7 is opened, and by raising the operation handle 6a of the head 6, the channels of the carbon dioxide hose 4 and the beer hose 7 are closed. The gas joint 6b and the beer joint 6c are detachable from the main body 6d extending vertically at the center of the head 6, and the gas joint 6b, the beer joint 6c and the main body 6d can be disassembled. Thus, the head 6 can be easily cleaned.

  The server 8 is connected to the head 6 via the beer hose 7, and has a function of cooling the beer liquid sent from the beer barrel 5 via the head 6 and the beer hose 7. The server 8 is a so-called electric cooling type instantaneous cooling type server, and inside the server 8 is a cooling device 9 that functions as a supply device that cools beer liquid from the beer hose 7 and supplies beverages to the currant 10. Is provided. The cooling device 9 includes a cooling tank 9a that stores cooling water therein, and a beer pipe 9b that is connected to the beer hose 7 and formed in a spiral shape inside the cooling tank 9a. A refrigerant pipe 9c connected to a refrigeration cycle apparatus (not shown) of the cooling device 9 is provided on the inner side surface of the cooling tank 9a vertically, and ice 9d is added to the refrigerant pipe 9c by the refrigeration cycle inside the refrigeration cycle apparatus. Is formed, the water in the cooling tank 9a is cooled, and the beer inside the beer pipe 9b is further cooled. In addition, the beer pipe 9b is formed in a spiral shape and ensures a long flow path for the beer liquid in the cooling tank 9a, so that the beer liquid in the beer pipe 9b is instantly cooled more preferably in the cooling device 9. Is done.

  In the present embodiment, an example in which the beer barrel 5 is provided outside the server 8 and the server 8 is an electric cooling instantaneous cooling server provided with a cooling device 9 is described. However, instead of the electric cooling type instantaneous cooling type server, an ice cooling type instantaneous cooling type server or a barrel storing type server in which the beer barrel 5, the head 6 and the beer hose 7 are provided in the refrigerator is used. It may be. Here, the ice-cooled instantaneous cooling server is a server in which ice is provided in the cooling tank and the beer pipe is cooled by the ice via a cold plate (not shown). Moreover, a barrel storage server is a server provided with the structure where the beer barrel, the head, and the beer hose were stored in the refrigerator, and the beer hose is cooled by this refrigerator.

  Here, it demonstrates in detail about the currant 10 which pours out the beer cooled by the cooling device 9. FIG.

  As shown in FIG. 2, the currant 10 includes a lever 11 that can be held and moved by a hand, a slide valve (not shown) that opens and closes a beer flow path inside the currant 10 by operating the lever 11, and a slide It comprises a currant body 13 that holds the valve so as to be movable inside, and a nozzle (pipe) 14 that extends vertically downward from the currant body 13.

  The lever 11 of the currant 10 is movable to the left side of FIG. 2 in a state where the user is located on the left side of FIG. Hereinafter, the lever 11 is formed in a substantially cylindrical shape extending upward from the currant body 13.

  The nozzle 14 extends vertically downward from the curran main body 13, and a flow path through which beer circulates is communicated with the beer flow path in the curran main body 13 inside the nozzle 14.

  A pouring member 20 for pouring the beer liquid in the liquid channel into the beverage container A is attached to the tip portion 14 a of the nozzle 14.

  As shown in FIGS. 2 and 3, the dispensing member 20 includes a bearing portion 21 that is attached to the tip portion 14 a of the nozzle 14, and a rotating portion 22 that is rotatably attached to the tip portion 14 a via the bearing portion 21. I have.

  The bearing portion 21 is an annular portion disposed coaxially with the tubular nozzle 14, and is interposed between the nozzle 14 and the rotating portion 22 to freely rotate the rotating portion 22 with respect to the nozzle 14.

  The rotating part 22 has a hexagonal annular side wall part 23 and a bottom part 22 a that closes the lower end opening of the side wall part 23, and is arranged coaxially with the tubular nozzle 14 like the bearing part 21. Therefore, the rotation axis R of the rotating unit 22 coincides with the central axis of the nozzle 14.

  The side wall portion 23 is formed around the rotation axis R of the rotating portion 22 and is constituted by six wall portions 23a to 23f. On the wall portions 23a to 23f, every other nozzle (in the present embodiment, on the wall portions 23a, 23c, and 23e) is provided with a dispensing nozzle 24 that extends outward. Each pouring nozzle 24 is a tubular member and communicates with the internal space of the rotating portion 22. Therefore, each pouring nozzle 24 can introduce beer in the rotating portion 22 into the inside and pour it out from the tip opening (pour-out port) 25.

As shown in FIG. 3, each of the three pouring nozzles 24 is bent so as to exhibit an L shape in plan view. More specifically, the three dispensing nozzles 24 bend at a bending angle θ ₁ (90 ° in FIG. 3) so as to face the same rotation direction (clockwise direction in FIG. 3) with respect to the rotation axis R of the rotating portion 22. ing. Therefore, the pouring direction D of the beer liquid poured out from the tip opening 25 of the pouring nozzle 24 is a direction different from the axial direction of the rotation axis R of the rotation unit 22 and the rotation axis R of the rotation unit 22 The direction does not intersect with the axial direction. The bending angle θ ₁ is preferably in the range of 90 ° to 135 °.

Incidentally, the three pouring nozzle 24, as shown in FIG. 2, the distal end is inclined at an inclination angle theta ₂ facing down. Inclination angle theta ₂ is equal to or less than 45 ° greater than, for example, 0 °.

  Then, operation | movement of each component at the time of pouring beer into the drink container A using the currant 10 is demonstrated, referring FIG.

  First, when the user of the beverage providing device 1 operates the lever 11 and a beer flow path from the currant body 13 to the nozzle 14 is established, the beer flows into the rotating portion 22 of the dispensing member 20 from the nozzle 14. To do. Then, the beer is poured out from the tip opening 25 through the pouring nozzle 24 communicating with the internal space of the rotating part 22. The beer poured out from the front end opening 25 collides with the inner surface of the beverage container A, for example, and flows down spirally toward the bottom of the beverage container A along the inner surface.

  As described above, the beer pouring direction D at this time is a direction different from the axial direction of the rotation axis R of the rotating portion 22 and a direction not intersecting with the axial direction of the rotating shaft R of the rotating portion 22. Therefore, a moment around the rotation axis R is generated by beer extraction. More specifically, the pouring nozzle 24 bent in the clockwise direction with respect to the rotation axis R generates a counterclockwise moment with respect to the rotation axis R in the rotating portion 22 as a reaction force for beer pouring. As shown in FIG. 4, the rotating portion 22 that can freely rotate with respect to the nozzle 14 by the action of the moment rotates the rotating portion 22 and the dispensing nozzle 24 integrally with respect to the rotation axis R counterclockwise. To do.

  Thus, in the above-described pouring member 20, the rotating portion 22 rotatably attached to the tip portion 14 a of the nozzle 14 rotates when beer is poured from the tip opening 25 of the pouring nozzle 24. At this time, the beer poured from the tip opening 25 of the dispensing nozzle 24 hits the inner surface of the beverage container A or the liquid surface of the beer in the beverage container A, and both the beer liquid and the foam rotate around the rotation axis R. Move in the direction and involve a lot of air during the movement.

  If most of the gas contained in the foam of beer is carbon dioxide, the specific gravity of the air present outside the foam and the specific gravity of the gas in the foam with a high carbon dioxide gas ratio are greatly different. Is prone to collapse. Therefore, as described above, the difference between the specific gravity inside the foam and the specific gravity outside the foam is alleviated by incorporating air into the beer and taking the air into the foam. As a result, the time until the foam collapses becomes longer and the foam retention is improved.

  That is, in the above-described pouring member 20, when the beer is poured out, the rotating unit 22 rotates, and a lot of air is caught in the beer.

  In addition, in the pouring member 20, since the rotating part 22 rotates when beer is poured out, the direction in which beer is poured out from the tip opening 25 of the pouring nozzle 24 is not always constant and time Changes over time. As a result, beer is injected into the beverage container A not only from one direction but also from various directions, and the beer is effectively mixed in the beverage container A.

  In general, it is desirable that beverages provided at restaurants and the like be homogeneous throughout the beverage container immediately after being poured into the beverage container, but many beverages contain multiple types of materials with different specific gravities. In addition, since the specific gravity of each of the plurality of types of materials is different, it tends to be inhomogeneous. By pouring beer using the pouring member 20 described above, beer is effectively mixed in the beverage container A, and the beer is homogenized.

  In the case where the sparkling beverage is a beverage composed of a plurality of types of liquids or a beverage containing a solid content, it tends to be non-homogeneous, but can be homogenized by using the dispensing member 20. Become. Examples of beverages containing solids include beverages in which powder is dissolved in liquid, and beverages made by adding liquid to powder. Examples of beverages composed of a plurality of types of liquid include beer beverages (so-called half-and-half) made by mixing two types of beer liquids in the same amount.

  In addition, since the dispensing nozzle 24 is a separate member from the side wall 23, the beverage can be changed by changing the shape of the dispensing nozzle or selecting a dispensing nozzle having a different shape as necessary. Can be easily changed.

  Note that the dispensing nozzle 24 is not limited to the nozzle having the shape described above, and various shapes of nozzles can be employed. For example, by changing the length or diameter of the pouring nozzle 24 or changing the size of the pouring opening 25, the rotational speed of the rotating portion 22 described above can be adjusted. As a method for increasing the rotation speed of the rotating portion 22, a method in which the diameter of the dispensing nozzle 24 is made smaller than the diameter of the nozzle 14, and the area of the internal space of the side wall portion 23 (area in a plane perpendicular to the rotation axis R) There are a method of reducing the cross-sectional area of the extraction nozzle 24, a method of making the diameter of the extraction opening 25 smaller than the diameter of the extraction nozzle 24, and the like.

  By increasing the rotation speed of the rotating part 22, the momentum of beer colliding with the inner surface of the beverage container A or the liquid level of the beer liquid in the beverage container increases, the carbon dioxide gas of the beer is appropriately released, and the taste and fragrance are increased. You can pour a beer that stands out. In addition, since foam can be formed at the same time when beer is poured out (ie, poured once), the amount of carbon dioxide contained in the beer liquid compared to when foam is separately formed (twice poured). The carbon dioxide is less likely to accumulate in the stomach. Furthermore, once-poured beer requires a technique that is high to some extent for the pourer, but by pouring using the above-described pouring member 20, it is possible to pour once even without high technical capabilities.

  FIG. 5 shows an example of a modification of the dispensing nozzle. Similarly to the above-described pouring nozzle 24, the pouring nozzle 24A of the rotating portion 22 shown in FIG. 5 communicates with the internal space of the rotating portion 22 and extends outward from the walls 23a, 23c, and 23e.

  However, unlike the above-described pouring nozzle 24, the pouring nozzle 24A is a tubular member that extends straight in the radial direction of the rotating portion 22, and the opening at the tip thereof is closed. The dispensing nozzle 24 </ b> A has a side surface opening (spouting port) 25 </ b> A provided on the side surface instead of the tip opening.

  Each of the side openings 25A of the three dispensing nozzles 24A is provided on the same side (counterclockwise side in FIG. 5) with respect to the rotation axis R of the rotating portion 22. Therefore, the pouring direction D of the beer liquid poured out from the side opening 25A of the pouring nozzle 24A is a direction different from the axial direction of the rotating shaft R of the rotating portion 22, and the rotating shaft R of the rotating portion 22 The direction does not intersect with the axial direction.

  Also in the rotating part 22 having such a pouring nozzle 24A, moments around the rotation axis R are generated by beer pouring, as in the rotating part 22 having the pouring nozzle 24 described above. That is, in the rotating unit 22, the rotating unit 22 and the dispensing nozzle 24 rotate clockwise about the rotation axis R. Therefore, homogenization of beer can be achieved also by the pouring member 22 provided with the rotating part 22 shown in FIG.

  In addition, in embodiment mentioned above, although the aspect which rotates the rotation part 22 with the reaction force of beer extraction was shown, you may rotate a rotation part with force other than the reaction force of beer extraction.

  For example, as shown in FIG. 6, the rotation unit 22 may be rotated by providing a propeller unit 27 in the rotation unit 22. The propeller portion 27 has three propellers 27b extending radially from the central portion 27a, and the propeller 27b extends to the wall portions 23b, 23d, and 23f of the side wall portion 23 and is fixed. Each propeller 27b is designed to be inclined in the same direction with respect to a horizontal plane (a plane orthogonal to the rotation axis R). Therefore, when beer flows from the nozzle 14 into the rotating portion 22, a moment around the rotation axis R is generated in the propeller portion 27 due to the inflow pressure. In the configuration shown in FIG. 6, a counterclockwise moment with respect to the rotation axis R is generated in the propeller portion 27. As a result, the rotating portion 22 that can freely rotate with respect to the nozzle 14 rotates counterclockwise with respect to the rotation axis R due to the moment.

  Also in the rotation part 22 having such a propeller part 27, the beer can be homogenized because it rotates about the rotation axis R, similarly to the rotation part 22 having the above-described dispensing nozzles 24, 24 </ b> A.

  In addition, since the rotation part 22 shown in FIG. 6 is not the rotation by the reaction force of beer extraction, there is no restriction | limiting regarding the extraction direction which pours out beer, and can design a spout freely. For example, as shown in FIG. 6, an opening 23g penetrating the wall portion of the side wall portion 23 is provided, and this opening 23g can be used as a spout.

  The present invention is not limited to the above embodiment, and various modifications are possible.

  For example, the number of extraction nozzles provided in the rotating unit is not limited to three, and may be one, two, four or more. Further, the side wall portion of the rotating portion is not limited to a hexagonal ring, and may be, for example, an annular ring or a polygonal ring other than a hexagon. Furthermore, the rotating portion does not necessarily have a side wall portion, and may be an embodiment in which, for example, the dispensing nozzle 24 is directly attached to the nozzle 14.
