BEST MODE FOR CARRYING OUT THE INVENTION One example of an embodiment of the present invention is shown in FIG.
4 and FIG. FIG. 1 is an overall configuration diagram of an example of an embodiment of the present invention, and FIG. 4 is an explanatory diagram of a mixer element section.

A dispensing head 2 is attached to a draft beer barrel 1. Carbon dioxide cylinder 3 to pressure regulator 4
The carbon dioxide gas depressurized by acts on the draft beer in the draft beer barrel 1, and the draft beer is squeezed out through the dispensing head 2.

The draft beer that has been pressed out passes through a cooling pipe 6 in a cooling tank 5 cooled by a refrigerating device and reaches a pouring pipe line 7 outside the tank. A liquid pouring valve B having a pouring nozzle and a foam pouring valve A having a pouring nozzle 9 are connected to an end of the pouring pipe line 7.

A mixer element 10 is incorporated in the pouring nozzle 9. The mixer element 10 is
As shown in FIG. 4, a plurality of blades 12a and 12b having different twisting directions as a stirring / mixing mechanism 12 are arranged in series in a mixer cylinder 11 having a throttle mechanism 11a at the upper end. . A step portion 11b is formed on the outer surface of the lower end portion of the mixer cylinder 11, and the step portion 11b is inserted until it abuts on the end portion of the pouring nozzle 9. It is held by the frictional force between the outer surface of the mixer cylinder 11 and. Then, the mixing mechanism 12
The ring-shaped stopper 13 is screwed to the lower end of the mixer cylinder 11 to prevent extraction.

As described above, since the mixer cylinder 11 is held by the pouring nozzle 9 by the frictional force, the stopper tube
By grasping 13 and pulling it out, the mixer cylinder 11 can be easily removed together with the stopper 13.

By removing the mixer element 10 in this manner, the foam pouring portion can be used as the liquid pouring portion. The plurality of blades 12a and 12b of the stirring / mixing mechanism 12 having different twisting directions may be fixed or rotatable.

The draft beer extruded by the gas pressure of carbon dioxide gas has its speed increased by passing through the throttle mechanism 11a of the mixer element 10, and the draft beer with large kinetic energy which has increased speed is stirred and mixed by the stirring / mixing mechanism 12. Good quality bubbles can be generated by being agitated and mixed by the plurality of blades 12a, 12b having different twist directions.

As described above, the following effects can be obtained by the structure in which the bubble pouring valve and the liquid pouring valve are provided in a branched manner. Conventionally, a single spout valve that can spout bubbles and liquids has been put into practical use.However, in this case, bubbles are left in the spout nozzle after foaming, and the bubble will remain in the nozzle during the next spout. The bubbles remaining in the first stage will be extracted into a container such as a jug, and a sparkling beverage such as beer will be extracted onto the bubbles. At this time, there was a problem that the initially poured foam became a core of foaming with respect to the foamed beverage extracted in a container such as a jug, and foaming was significantly induced to become full of foam. Further, the finer the foam quality of the foam remaining in the pouring nozzle which is first poured, the more the foaming is induced. For this reason, in order to suppress foaming, foaming is performed so that the quality of the foam is roughened so that there is no hindrance to pouring after foaming. However, since this foam has large foam particles, it was impossible to obtain a high-quality foam, such as immediately defoaming.

In the present invention, the liquid pouring outlet and the foam pouring outlet are separately provided, and an appropriate amount of liquid is extracted from the liquid pouring outlet into a container such as a jug, and then an appropriate amount of foam is poured from another foam pouring outlet. Since it is configured so as to be possible, it is possible to solve the above-mentioned problem after foaming when beer is poured out by one pouring valve and then bubbles are poured out. Also, at the foam pouring outlet, an ideal foam quality can be obtained due to the mixing effect of the mixer element.

Further, when the mixer element of the pouring valve A is removed, the liquid pouring outlet becomes two places (a plurality), and beer and non-beer carbonated drinks (cola, cola, When it is necessary to frequently pour water such as carbonated water), it can be poured efficiently.

Next, the overall construction of another embodiment will be described with reference to FIG. In this example, draft beer that has been pressed out through the dispensing head 2 is divided into two cooling pipes 6a and 6b in the cooling tank 5, and is provided with a foam pouring valve A and a liquid pouring valve B, respectively. It is connected to the outlet line 7.

As a result, chilled beer can be extracted from the liquid pouring outlet and the foam pouring outlet as compared with the case of FIG. Furthermore, the overall configuration of another embodiment will be described with reference to FIG.

In this example, draft beer barrels 1a, 1b and 2
The draft beer individually provided and extruded from each of the draft beer barrels is sent to the cooling pipes 6a and 6b of the two systems in the cooling tank 5, and is poured from the foam pouring valve A and the liquid pouring valve B. It is supposed to be served. That is, the circuit of the bubble pouring valve A and the liquid pouring valve B is provided in parallel.

One is used exclusively for liquid pouring and the other is used exclusively for foam pouring. When the mixer element at the foam pouring outlet is removed, both can be used as liquid pouring. In recent years, for example, different kinds of beer (including different kinds of beverages)
There is also an example in which is mixed with an appropriate ratio and used for drinking. In such a case, in the example shown in FIG. 3, different types of beer can be poured out from different paths, so an appropriate amount of beer is poured into a container such as a jug from the liquid pouring outlet and another beer is poured from the foam pouring outlet. In addition, when the mixer element at the foam pouring outlet is removed, different types of beer can be separately poured out, and the beer can be served as a mixed beer.

Next, another example of how to attach the mixer element 10 to the pouring nozzle 9 will be described with reference to FIG. A mixer element 10 incorporating a mixing mechanism 12 is inserted into the pouring nozzle 9. A male screw is formed at the lower end of the pouring nozzle 9. Then, the mixer element 10 is prevented from being pulled out by screwing a ring-shaped stopper 14 having a female screw formed to be screwed into the male screw.

Then, by removing the stopper 14, the mixer element 10 can be easily removed. Instead of the ring-shaped stopper 14 with a screw, a bayonet-type ring-shaped stopper that is inserted into the lower end of the pouring nozzle 9 and then rotated to prevent the stopper from coming off is locked. Good.

In the above example, the mixer element 10
Has been described above, the short pipe containing the mixer element 10 may be incorporated into the foam pouring pipe line 7 in the form of a threaded joint.

[0023]

EFFECTS OF THE INVENTION The draft beer pouring device of the present invention is as described above, and uses the kinetic energy of draft beer extruded by the gas pressure of carbon dioxide gas to stir and mix with a mixer element to obtain good quality. Foam can be generated. Further, the structure is such that the mixer element can be easily attached and detached, and when the mixer element is removed, the foam pouring outlet can be used as a liquid pouring outlet.
