Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage dispenser and a beverage dispensing system including the beverage dispenser, and more particularly, to a beverage dispenser for dispensing and dispensing a foamed beverage in which gas dissolved in the beverage naturally foams.
And a beverage dispensing system.

[0002]

2. Description of the Related Art Heretofore, there has been known a beverage dispenser which automatically and quantitatively pours a sparkling beverage such as beer or low-malt beer into a drinking container such as a paper cup, a glass, or a mug. The beverage dispenser is arranged such that a sparkling beverage is introduced from a beverage container provided outside the beverage dispenser through an external pipe, and the introduced sparkling beverage passes through a cooling water tank provided inside. It is cooled through the internal pipe and discharged from the outlet end of the internal pipe into a drinking container to distribute and discharge the sparkling beverage.

[0003] Here, a gas such as carbon dioxide gas is dissolved in the sparkling beverage, and when the sparkling beverage is poured into a drinking container, the dissolved gas is liberated from the beverage to foam spontaneously, and foam is generated. appear. This foam is called natural foaming.For example, when beer is poured into a mug, carbon dioxide is released from the beer poured into the mug, and the released carbon dioxide is deposited as natural foam on the liquid level of the beer. This is one factor that visually stimulates the taste.

However, natural foaming tends to disappear due to the coarse grain of the foam, and the function as a lid for suppressing the escape of carbon dioxide contained in beer lasts only for a short time. Is said to be easily reduced.

Therefore, a certain beer dispenser is
Inside the dispenser, foam with a finer grain than natural foam (hereinafter referred to as creamy foam) is created. During beer pouring, beer is poured so as to suppress the occurrence of natural foam, and a predetermined amount of beer is discharged. After being poured, the creamy foam produced is additionally placed on the beer surface in a predetermined amount to optimize the beer-to-foam ratio (ratio between the height up to the beer liquid level and the foam-only height). However, about 7: 3 to 8: 2), the flavor of the beer is maintained for a long time.

This type of beer dispenser is designed to reduce the head drop of beer to be poured by tilting the mug in order to suppress the occurrence of natural foaming during beer pouring, and the beer poured into the mug. The liberation of carbon dioxide gas is reduced by reducing the agitation force of the gas.

[0007]

By the way, the conventional beer dispenser connects the internal pipe through which the beer passes or a beverage container such as a beer barrel to the dispenser and introduces the beer stored in the beer barrel into the dispenser. The external piping to be used is generally configured by connecting various joints and a plurality of pipes in series, and the inner diameters of these joints and the plurality of pipes are different from each other.

For this reason, the flow rate of beer passing through the inside of these pipes changes at the portion where the inner diameter changes, and this change in the flow rate disturbs the rectification state of the beer, promotes the release of carbon dioxide gas, and spontaneously foams. Increase. Therefore, even if the posture of the mug during beer pouring is improved, natural foaming already generated inside the pipe cannot be reduced,
Natural foaming could not be reduced sufficiently. Such a problem is not limited to the beer dispenser for dispensing and dispensing beer, but also applies to a beverage dispenser for dispensing and dispensing other sparkling beverages.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a beverage dispenser and a beverage dispensing system capable of suppressing occurrence of natural foaming before pouring of a sparkling beverage.

[0010]

In order to achieve the above object, a beverage dispenser according to the present invention (Claim 1) distributes a foamed beverage introduced from the outside and passed through an internal pipe to a predetermined drinking container. In the outgoing beverage dispenser,
The inner diameter of the pipe from the supply end where the sparkling beverage is introduced to the pouring end where the sparkling beverage is discharged into the drinking container is formed substantially uniformly.

Here, the outside means the outside of the beverage dispenser, for example, a beverage container containing and storing a sparkling beverage. In addition, sparkling beverages,
Also includes beer, low-malt beer similar to beer, and other carbonated beverages. In addition, the drinking container includes a paper cup, a plastic cup, a glass, a cup, a mug, and the like, and also includes a pitcher for distributing to the mug and the like, which is not directly used for drinking.

The pipes include not only tubular pipes and tubes, but also joints for connecting these pipes and the like, and various sensors connected to a piping system through which the beverage passes to detect the flow rate and the like. And the like.
The term “substantially uniform” means that the inner diameter does not need to be physically the same value physically in all the cross sections of the pipe, and the ratio of the minimum value to the maximum value of the internal diameter may be, for example, 70% or more. Is 80% or more, more preferably 90% or more, and optimally 100%. Further, in addition to forming the inner diameter substantially uniformly, a portion where the inner diameter changes within a substantially uniform range is formed not smoothly but smoothly so that the inner diameter changes continuously. This is preferable because the rectification state of the sparkling beverage is not easily disturbed.

According to the beverage dispenser according to the first aspect, the inner diameter of the pipe from the supply end where the sparkling beverage is introduced to the pouring end where the sparkling beverage is discharged into the drinking container is substantially uniform. Due to the formation, the disturbance of the rectification state of the sparkling beverage generated in the portion where the inner diameter of the pipe changes is suppressed, and the gas dissolved in the beverage is prevented from being released from the beverage, and as a result, natural foaming in the pipe is suppressed. Can be reduced.

Although the present invention is directed to a beverage dispenser for a sparkling beverage in which spontaneous foaming occurs, it does not prevent the invention from being applied to a beverage dispenser for a beverage other than the sparkling beverage. Even when applied to a beverage dispenser for beverages, it does not disturb the straightening state of the beverage in the piping, which reduces the resistance to the flow of the beverage and stabilizes the flow rate of the beverage to be poured into the drinking container. Can be planned.

Further, the beverage dispenser of the present invention (claim 2) is the beverage dispenser according to claim 1,
The ratio of the minimum value to the maximum value of the inner diameter of the pipe is 70%
It is characterized by the above.

This is a concrete example of the uniformity of the inner diameter of the pipe. The closer this ratio is to 100%, the smaller the bubble ratio of natural foaming is, which is preferable. According to the study of the present inventors, When this ratio is 70%, the bubble ratio sharply decreases, and the generation of natural bubbles can be improved satisfactorily. In addition, when the ratio is about 70%, a pipe having a substantially uniform inner diameter (ratio 70%) is used. The cost required for manufacturing does not increase. Therefore, according to the beverage dispenser of the second aspect, it is possible to suppress the occurrence of natural foaming without increasing the cost, and to realize a suitable cost performance.

[0017] The foam ratio refers to the natural foaming itself deposited on the liquid surface of the beverage relative to the height of the liquid beverage portion when the foamed beverage is poured into a glass having a substantially uniform diameter in the height direction. It refers to the ratio of height.

Further, a beverage dispenser according to the present invention (claim 3) is characterized in that in the beverage dispenser according to claim 1 or 2, the pipe is connected to a plurality of partial pipes. The pipe inside the beverage dispenser may be a single pipe, but is generally configured by connecting a plurality of pipes (partial pipes) with a joint or the like. In the case of the pipes connected by the above, the inner diameter of all the partial pipes is substantially uniform, or the ratio of the minimum value to the maximum value among the inner diameters of all the partial pipes is 70% or more. Thus, the effects of the first or second aspect of the invention can be exhibited.

Further, the beverage dispensing system of the present invention (claim 4) comprises: a beverage container containing a sparkling beverage;
A beverage dispenser for distributing and dispensing the sparkling beverage introduced from the outside and passing through the internal piping to a predetermined drinking container, one end of the beverage dispenser connected to the beverage container, and the other end connected to the beverage dispenser, And an external pipe for introducing the sparkling beverage sent from the dispenser into the beverage dispenser, wherein the sparkling beverage is discharged into the drinking container from a supply end where the sparkling beverage is introduced. An inner diameter of the inner pipe reaching the pouring end and an inner diameter of the outer pipe extending from the one end to the other end are formed substantially uniformly.

In the beverage dispenser of the invention described above, only the inside (pipe) inside the beverage dispenser is formed to have a substantially uniform inner diameter. In the beverage dispensing system according to the fourth aspect, the foamed beverage is stored. The inner diameter of the beverage container is substantially uniform, including the external piping connecting the stored beverage container and the beverage dispenser, and the entire piping (the internal piping and the external piping) through which the foamed beverage passes is formed. By forming the inside diameter to be substantially uniform, it is possible to further suppress the occurrence of natural foaming as compared to the case where the inside diameter of only the internal pipe of the beverage dispenser is formed to be substantially uniform.

The term “substantially uniform” means that the inner diameter does not need to be physically the same in all the cross sections of the pipe, and the ratio of the minimum value to the maximum value of the internal diameter is, for example, 70% or more. Preferably 80% or more, more preferably 9%
0% or more, optimally 100%. In addition, in the present invention, in addition to forming the inner diameter substantially uniform, the portion where the inner diameter changes within a substantially uniform range is not suddenly changed, but is smooth, that is, the inner diameter is continuously changed. It is preferable to change the shape so that the rectification state of the sparkling beverage is not easily disturbed.

Also, the present invention is a beverage dispensing system for a sparkling beverage in which natural foaming occurs,
It does not prevent application to beverage dispensing systems for beverages other than sparkling beverages, and even when applied to beverage dispensing systems for beverages other than sparkling beverages, it may disturb the straightening state of the beverage in the piping. Therefore, the resistance to the flow of the beverage is reduced, and the flow rate of the beverage to be poured into the drinking container can be stabilized.

In the beverage dispensing system according to the present invention, the ratio of the minimum value to the maximum value of the inner diameters of the internal pipe and the external pipe is 70% or more. There is a feature.

This is a concrete example of the uniformity of the inner diameter of the entire pipe. The closer this ratio is to 100%, the smaller the natural foaming ratio becomes, which is preferable. For example, when the ratio is 70%, the bubble ratio sharply decreases, and the generation of natural bubbles can be satisfactorily improved. When the ratio is about 70%, the inner diameter is substantially uniform (ratio 70%). The cost required to manufacture the piping does not increase. Therefore, according to the beverage dispenser according to claim 5, without increasing the cost,
Natural foaming can be suppressed, and suitable cost performance can be realized.

Further, in the beverage dispensing system according to the present invention (claim 6), in the beverage dispensing system according to claim 4 or 5, the internal pipe of the beverage dispenser is connected to a plurality of partial pipes. It is characterized by the following. The internal pipe of the beverage dispenser may be a single pipe, but is generally configured by connecting a plurality of pipes (partial pipes) by a joint or the like. In the case of connected pipes, the inner diameters of all partial pipes and external pipes are substantially uniform, or the ratio of the minimum value to the maximum value of the internal diameters of all partial pipes and external pipes is 70% or more. Claim 4 described above.
Alternatively, the effects of the invention according to claim 5 can be exhibited.
