Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bubble removing device for a carbon dioxide beverage and a server equipped with the device, and more particularly to a draft beer service device for supplying draft beer from a draft beer barrel to a jug or the like via an instant cooling type beer server.

[0002]

[Prior art]

 FIG. 4 is a block diagram showing an instant cooling type draft beer server.

Carbon dioxide gas is supplied from a carbon dioxide gas cylinder 81 to a fitting 84 of the raw beer barrel 80 via a pressure regulating valve 82 and a gas hose 83. The draft beer in the draft beer barrel 80 is pressed by the carbon dioxide gas supplied from the fitting 84, and is supplied to the beer supply hose 86 via the down tube 87 and the fitting 85. The draft beer supplied to the beer supply hose 86 is cooled when passing through the cooling coil 91 of the server main body 96 of the instant cooling type draft beer server 90. The cooled draft beer is poured into the glass 93 or the like when the pouring valve 92 is opened. The cooling coil 91 is cooled by the cooling water in the cooling water tank 94, which is cooled by the cooling unit 95. Reference numeral 88 is a bubble removing device, which will be described later, provided with a gas vent valve 89.

When the beer in the draft beer barrel 80 is exhausted and emptied and the pouring is continued in a state filled with carbon dioxide gas, carbon dioxide gas is inevitably mixed in the beer supply hose 86 and the cooling coil 91. If the empty draft beer barrel 80 is newly replaced in this state and the pouring operation is performed again, the carbon dioxide gas and the beer are poured in a mixed state at the beginning, so that stable pouring cannot be performed. In extreme cases, a few mugs of beer are wasted. In order to solve this, a foam removing device may be used in some cases.

Here, the bubble cutting device will be described.

As shown in FIGS. 4 and 5, the bubble removing device 88 includes a cylindrical body 97, and a top plate 99 and a bottom plate 98 fixed to the upper and lower ends of the cylindrical body 97, respectively. A gas vent 101 is formed on the top plate 99, and a beer inlet 103 and a beer outlet 104 are formed on the bottom plate 98. The outlet of the beer supply hose 86 is connected to the beer inlet 103, and the inlet of the cooling coil 91 is connected to the beer outlet 104. Further, the gas vent port 101 is provided with a gas vent valve 89 via a conduit.

The liquid level of beer in the whipping device 88 is held at an appropriate fixed position, and when the amount of beer in the draft beer barrel 80 becomes low and carbon dioxide gas is mixed in the beer to be poured out. Immediately, the pouring valve 92 is closed to stop the pouring operation, and the draft beer barrel 80 is replaced (note that the fitting 85 has a check valve, so that the backflow of beer does not occur). After that, the gas vent valve 89 is opened to guide the carbon dioxide gas in the beer supply hose 86 to the bubble removing device 88, but the carbon dioxide gas passes through the beer 102 and the beer 102 is entangled and it takes a long time to settle down. Standing time is necessary. Generally, it is about 30 seconds, and when it is long, it is about 60 seconds.

When carbon dioxide gas is separated from beer in the beer supply hose 86 or the like during normal pouring due to high temperature or low pressure, the gas enters the bubble removing device 88, and The beer 86 cannot be smoothly poured out because the beer 86 is caught.

[0009]

[Problems to be solved by the device]

 In the above conventional technology, since the liquid inlet and the liquid outlet are not partitioned, the liquid near the liquid outlet is drastically diffused in the bubble cutting device, and the beverage must be poured out quickly when the beverage container is replaced. Despite the situation, it requires a long waiting time, resulting in poor service. Further, if carbon dioxide gas is separated in a beer hose or the like even during normal pouring, beer is smeared in the vicinity of the liquid outlet in the bubble removing device, which prevents smooth beer pouring.

The present invention has been made in view of the above-mentioned problems of the conventional technique, and a carbon dioxide beverage can be immediately poured out after replacement of a foam cutting device and a beverage container that can quickly perform foam cutting, The objective is to provide a server that can continue pouring even if carbon dioxide separation occurs.

[0011]

[Means for Solving the Problems]

 A bubble removing device of the present invention for achieving the above object, an outer cylinder, an inner cylinder shorter than the outer cylinder, which is provided in the outer cylinder, and a lower end portion of the outer cylinder and the inner cylinder. A bottom plate having a liquid inlet communicating with the inner cylinder and a liquid outlet communicating with the outer cylinder, and a top plate provided at the upper end of the outer cylinder having a gas vent port. .

In addition, the server of the present invention supplies carbon dioxide gas into a beverage container that stores the carbon dioxide gas beverage, and transfers the carbon dioxide gas beverage from the beverage container to the server body by the gas pressure. In the server for carbon dioxide beverages to be poured out, the bubble removing device of the present invention is used to connect the beverage container and the server main body so that the liquid inlet and the liquid outlet communicate with the beverage container and the server main body, respectively. It is characterized by being interposed between them.

[0013]

[Action]

 In the present invention configured as described above, in the unlikely event that carbon dioxide gas or a liquid mixture containing carbon dioxide gas is supplied from the liquid inlet into the inner cylinder of the bubble removing device, the carbon dioxide gas moves upward. Then, the liquid is separated from the liquid and discharged from the degassing device to the outside of the bubble removing device. On the other hand, the liquid overflows from the inner cylinder, is stored in the outer cylinder outside the inner cylinder, and exits from the liquid outlet. In this way, since the liquid inlet and the liquid outlet are separated by the inner cylinder, the liquid is contained in the inner cylinder of the bubble eliminator, the liquid is not contained in the vicinity of the liquid outlet, and the liquid is separated from the foam. Flows out of the liquid outlet, and the bubbles are removed quickly.

According to the present invention as set forth in claim 2, when the beverage container is replaced, the bubbles are quickly removed, so that the liquid can be smoothly dispensed immediately after the replacement.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a beer server equipped with a frothing device of the present invention, FIG. 2 is a cross-sectional view of the frothing device of the present invention, and FIG. 3 is a control block of the beer server shown in FIG. It is a figure.

As shown in FIG. 1, in this beer server, a beer supply hose 7 has a cooling coil 9 side provided with a bubble removing device 16 to be described later of the present invention, and a beer supply hose 7 fitting 5 side has a liquid shortage sensor. 18 is provided. Other configurations are the same as those of the conventional example.

As shown in FIG. 2, the bubble removing device 16 is provided with an inner cylinder 20 in an outer cylinder 19 and a lower end surface thereof fixed to a bottom plate 21, and a solenoid valve 17 to a gas vent 24 via a conduit. Is provided. The lower end of the inner cylinder 20 and the lower portion of the outer cylinder 19 are sealed by a seal member (not shown). That is, the beer entrance 22 and the beer exit 23 are separated by the inner cylinder 20. The outer cylinder 19 and the bottom plate 21, or the outer cylinder 19 and the top plate 25 may be integrally formed.

Next, a control block diagram of the beer server will be described with reference to FIGS. 1 and 3.

The spout valve 14 is opened and closed by a plunger 32 controlled by a plunger drive circuit 31. The solenoid valve 17 is opened and closed by the valve opening / closing circuit 33. The server operation unit 29 includes a first switch 27 and a second switch 28, and when the first switch 27 is turned on, the CPU 30 outputs an instruction to the plunger drive circuit 31 to open the pouring valve 14. Then you can start pouring out the beer. Further, when the second switch 28 is turned on, the CPU 30 outputs a command for closing the dispensing valve 14 to the plunger drive circuit 31, and the dispensing can be completed. The liquid shortage sensor 18 is of a capacitance type, and when it is detected that beer has run out in the draft beer barrel 1 and the beer passing through the beer supply hose 7 contains a large amount of foam, This is output to the CPU 30, and the CPU 30 outputs to the plunger drive circuit 31 a command to close the pouring valve 14 accordingly. The solenoid valve 17 is opened for a predetermined time by the CPU 30 via the valve opening / closing circuit 33 at the time when the pouring operation is started by turning on the first switch 27. The bubbles contained in the beer in 7 are discharged to the outside via the bubble removing device 16. When the beer in the beer supply hose 7 contains a large amount of bubbles, the liquid shortage sensor 18 is a well-known one and has two electrode surfaces (sensor surfaces) to detect the capacitance between the electrodes. If the detected value suddenly changes, the fact is output to the CPU 30.

Next, the operation of the beer server of this embodiment will be described with reference to FIGS. 1 to 3.

The liquid level of the beer 26 in the bubble removing device 16 is held between the upper end of the outer cylinder 19 and the upper end of the inner cylinder 20, and in the initial state, the solenoid valve 17 and the pouring valve 14 are closed. It In this state, by releasing the carbon dioxide gas cylinder 2, carbon dioxide gas is injected into the draft beer barrel 1 via the pressure regulating valve 3 to apply the pressure necessary for beer pouring. Next, when the switch 27 of 1 is turned on, the CPU 30 outputs a command to open the dispensing valve 14 to the plunger drive circuit 31, and the plunger 32 opens the dispensing valve 14. As a result, the draft beer in the draft beer barrel 1 is poured into the glass 13 from the pouring valve 14 through the down tube 8, the fitting 5, the beer supply hose 7, the foam removing device 16 and the cooling coil 9. When it is desired to finish the beer pouring, when the second switch 28 is turned on, the pouring valve 14 is closed and the beer pouring is finished.

When carbon dioxide gas is significantly separated from beer in the beer supply hose 7 or the like during normal pouring due to high temperature or low pressure, carbon dioxide gas enters the bubble removing device 16, The carbon dioxide gas moves upward and is separated from the beer 26, while the beer 26 overflows from the inner cylinder 20 and is stored in the outer cylinder 19 outside the inner cylinder 20 and flows out from the beer outlet 23. As described above, the beer 26 is spilled in the inner cylinder 20 of the bubble removing device 16, and the beer 26 is not spilled in the vicinity of the beer outlet 24, so that the beer is quickly removed. It can be transferred and beer can be smoothly poured out. The beer pouring operation is repeated, and when the beer in the draft beer barrel 1 is exhausted during the beer pouring and bubbles are supplied from the draft beer barrel 1 to the beer supply hose 7, it is detected by the liquid shortage sensor 18. As a result, the CPU 30 outputs a command for closing the dispensing valve 14 to the plunger drive circuit 31, and the beer dispensing can be completed. Thereafter, when the draft beer barrel 1 is newly replaced and the first switch 27 is turned on, the CPU 30 outputs a command to the valve opening / closing circuit 33 so that the electromagnetic valve 17 of the foam removing device 16 is opened for a certain period of time. Bubbles (due to carbon dioxide gas) in the beer supply hose 7 can be discharged to the outside through the gas outlet 24, the conduit and the solenoid valve 17, and the beer can be smoothly poured out.

In the above-described embodiment, the solenoid valve is opened for a certain period of time immediately after the first switch is turned on after the draft beer barrel is replaced, but the invention is not limited to this. Open the solenoid valve of the bubble-eliminating device for a certain period of time, or install a timer in the CPU, replace the draft beer barrel, turn on the first switch, and after a predetermined time set in the timer of the CPU, The solenoid valve may be opened by the CPU for a certain period of time. Furthermore, the solenoid valve may be temporarily opened before the beer is poured out.

In the above embodiment, an outer cylinder having an outer diameter, an inner diameter, and a length of 75 mm, 65 mm, and 200 mm, and an inner cylinder having an outer diameter, an inner diameter, and a length of 40 mm, 30 mm, and 130 mm, respectively, are used. Set the beer flow rate to 50 ml / sec, the height of the liquid level of the beer in the bubble removing device to 150 mm (20 mm higher than the upper end of the inner cylinder), and carbon dioxide gas in the beer supply hose. Then, when I changed the draft beer barrel and then poured out the beer, I was able to pour out the beer smoothly from the first glass.
