Description

  The present invention relates to a beer pouring device having excellent cleaning efficiency, and more particularly to a beer pouring device capable of efficiently raising the temperature of an antifreeze when washing a beer passage.

  Conventionally, in a beer pouring device, in order to prevent the growth and adhesion of foreign substances such as yeast, after using the pouring device, a washing operation for washing the beer passage (cooling serpentine, etc.) in the device is performed. There must be.

  However, if the cleaning solution is immediately passed through the cooling serpentine tube immersed in the antifreeze solution after use, the cleaning solution (for example, water) freezes and the passage is clogged because the antifreeze solution has a negative temperature. This makes cleaning impossible.

For this purpose, when washing, the frozen liquid cooled to the minus temperature must be raised to the plus temperature once in advance.
That is, it is necessary to raise the temperature of the antifreeze liquid (usually at a negative temperature) by leaving it at room temperature for a long time, and to raise the temperature so that the water does not freeze even when the washing water flows through the cooling serpentine tube, that is, higher than 0 degree.

For this reason, a method has been developed in which a heater is provided in the cooling water tank of the beer pouring device to positively warm the antifreeze and raise the temperature higher than 0 ° C., and at the same time warm the cooling serpentine (see Patent Document 1).
If this method is adopted, the temperature of the antifreeze liquid is raised by the heater, so that it is not necessary to raise the temperature of the antifreeze liquid at room temperature for a long time.

JP-A-2006-44690

However, even if this method is adopted, it is necessary to warm the entire antifreeze liquid contained in the cooling water tank.
Since the heat capacity of the entire antifreeze liquid is large, it still takes time to raise the temperature, which is not always satisfactory from the point of temperature raising efficiency.
That is, although it is only necessary to warm the antifreeze around the cooling serpentine, the antifreeze in the region having a large heat capacity, that is, the antifreeze in the entire cooling water tank including the cooling pipe other than the cooling serpentine is warmed, resulting in poor thermal efficiency. Of course, both time and cost will increase.
The present invention has been made against the background described above.
That is, an object of the present invention is to solve the problems of the conventional beer pouring device and to provide a beer pouring device capable of efficiently raising the antifreeze in advance when cleaning the beer passage.

  As a result of intensive investigations to solve the above problems, the present inventors have found that a temperature rise region with a small heat capacity can be secured by arranging a partition sleeve between the cooling serpentine tube and the cooling pipe. Based on this, the present invention has been completed.

  That is, the present invention includes (1) a cooling water tank having antifreeze, a cooling pipe (refrigerant evaporating pipe) for cooling the antifreeze in the water tank, and a cooling serpentine (drinking water cooling pipe) disposed inside the cooling pipe. A beer pouring device comprising a stirrer disposed in the center of the inner side, wherein a partition sleeve is disposed between the cooling serpentine tube and the cooling pipe, and a heater is disposed inside the partition sleeve. Exists in the output device.

  Further, according to the present invention, (3), the auxiliary moving sleeve comprises an upper auxiliary moving sleeve and a lower auxiliary moving sleeve. The upper auxiliary moving sleeve is inserted into the partition sleeve so as to be movable up and down, and the lower auxiliary moving sleeve is also moved up and down. It exists in the beer extraction apparatus of the said (2) description inserted freely outside.

  Moreover, this invention exists in the beer extraction apparatus of the said (2) description to which the movement of (4) and an auxiliary | assistant moving sleeve is performed by an up-and-down moving means.

  Moreover, this invention exists in the beer extraction apparatus of the said (1) description to which the drinking liquid supplied to (5) and a beer extraction apparatus is previously cooled with the cooling device using antifreeze.

  Moreover, this invention exists in the beer extraction apparatus of the said (1) description by which the drink liquid supplied to a beer extraction apparatus is cooled previously with the cooling device using cooling water.

  Moreover, this invention exists in the beer extraction apparatus of the said (1) description in which the drink liquid barrel for supplying a drink liquid to a beer extraction apparatus is cooled by the refrigeration apparatus.

  In addition, as long as the objective of this invention is met, the structure which combined said (1)-(7) is also employable.

The beer pouring device of the present invention can efficiently raise the temperature of the antifreeze in advance when washing the drinking water passage.
In the closed state, the inner side of the partition sleeve becomes a closed region, and the antifreeze liquid cannot move between the inner side and the outer side, and warms efficiently in a region having a small heat capacity.

(Beer pouring device)
The beer pouring device A of the present invention cools the beer being transferred from the beer barrel T to the beer cock 7 at the most advanced portion through the cooling serpentine 3 disposed in the cooling water tank 1 filled with the antifreeze liquid. It is a device that pours beer of minus temperature.
Further, when the beer passage is washed, the beer passage is also a device that can be preheated with an antifreeze solution in advance and prevent the washing water from becoming iced in the cooling serpentine.
As a method for cleaning the cooling serpentine tube, for example, a method of supplying a cleaning liquid from the connection port 10 and discharging the beer cock 7 together with dirt is adopted.

Here, FIG. 1 is a front view showing the appearance of the beer pouring device according to the embodiment of the present invention, and FIG. 2 is a side view showing the appearance of the beer pouring device.
FIG. 3 is a side cross-sectional view showing the internal structure of the beer pouring device in a partial cross section, showing an open state.
FIG. 4 is a front sectional view showing the internal structure of the beer pouring device in a partial cross section, and shows an open state.
Moreover, FIG. 5 is a top view which shows the internal structure of a beer extraction apparatus, and shows an open state.

  The beer pouring device A is connected to a beer barrel T located in a separate place, and a carbon dioxide gas cylinder 13 is connected to the beer barrel T for applying pressure to beer.

By the way, a rectangular parallelepiped cooling water tank 1 containing an antifreeze liquid is provided above the beer pouring device A of the present invention.
The cooling water tank 1 is provided with a cooling pipe 2 wound in a coil shape through which a cooling medium such as liquid nitrogen passes. Inside the cooling pipe 2 is cooled in a coil shape through which a drinking liquid such as beer passes. A serpentine tube 3 is provided.

  A partition sleeve 4 is disposed between the cooling serpentine tube 3 and the cooling pipe 2, and an agitating screw 6 driven by a motor or the like is disposed at the inner center of the cooling serpentine tube 3. Thus, the antifreeze liquid Y is stirred and cooled uniformly.

The partition sleeve 4 has an advantage that the region of the antifreeze liquid is divided into two inside and outside and the movement of the antifreeze liquid can be suppressed.
A heater 5 is disposed inside the partition sleeve 4.
As will be described later, the heater 5 is for heating the antifreeze liquid Y at the time of cleaning after use, and a rod-like electric type is used from the viewpoint of heating efficiency.

Here, the partition sleeve 4 will be described in more detail.
FIG. 6 is a diagram for explaining the moving state of the auxiliary moving sleeve, showing the open state, and FIG. 7 is a diagram for explaining the moving state of the auxiliary moving sleeve, showing an intermediate state between the open state and the closed state.
FIG. 8 is a diagram for explaining the movement state of the auxiliary movement sleeve and shows a closed state.
The partition sleeve 4 includes an auxiliary movement sleeve. In the present invention, the provision of this auxiliary movement sleeve is one of the major features.
The auxiliary moving sleeve includes an upper auxiliary moving sleeve 41 and a lower auxiliary moving sleeve 42.
An upper auxiliary moving sleeve 41 is extrapolated to the partition sleeve 4 so as to be movable up and down, and a lower auxiliary moving sleeve 42 is also extrapolated so as to be movable up and down.
These movements in the vertical direction are easily performed by operating the vertical movement means using, for example, link means described later.

When the upper auxiliary moving sleeve 41 is located at the bottom dead center, the lower auxiliary moving sleeve 42 is located at the top dead center (open state), and when the upper auxiliary moving sleeve 41 is located at the top dead center, the lower auxiliary moving sleeve 41 is located at the top dead center. The moving sleeve 42 is located at the bottom dead center (closed state).
That is, the auxiliary moving sleeve serves to make the partition sleeve 4 extendable in the vertical direction.
Therefore, in the open state, the inside of the partition sleeve 4 communicates with the outside, and the antifreeze liquid can freely flow inside and outside.

On the other hand, in the closed state, the inner side of the partition sleeve 4 becomes a closed region, and the inner side and the outer side are partitioned so that the antifreeze liquid cannot flow.
The auxiliary moving sleeve not only suppresses the flow of the antifreeze liquid, but also functions to partition the inside of the cooling water tank 1 into the inner side and the outer side to eliminate a large flow movement of the antifreeze liquid from the inner region to the outer region.

When warming the antifreeze during cleaning, it is only necessary to warm the region of the antifreeze inside the partition sleeve 4 in the cooling water tank in the closed state as described above.
The inner antifreeze region has a smaller heat capacity than the entire antifreeze region, so that the temperature rises faster, shortening the time and improving efficiency.
As described above, the agitator 6 is agitated so that the temperature of the antifreeze rises uniformly during cleaning.

(Vertical movement means)
Here, vertical movement means for moving the upper auxiliary movement sleeve 41 and the lower auxiliary movement sleeve 42 will be described (see FIGS. 6 to 8).
The lower auxiliary moving sleeve 42 is fixed to the moving rod 42A, and the upper auxiliary moving sleeve 41 is guided by the moving rod 42A and is slidable up and down along the partition sleeve 4.
A coil spring 43 acting between the lower auxiliary moving sleeve 42 and the upper auxiliary moving sleeve 41 is mounted on the moving rod 42A.

An outer insertion tube 41A is attached to the upper portion of the upper auxiliary movement sleeve 41, and a moving rod 42A is inserted through the outer insertion tube 41A.
The moving rod 42A is attached to the lower part of the lower auxiliary moving sleeve 42.
Guide slits 41S and 42S are formed in the upper auxiliary moving sleeve 41 and the lower auxiliary moving sleeve 42, respectively.
The projections P1 and P2 formed on the partition sleeve 4 are fitted in the guide slits.
When the projections P1 and P2 abut against the upper and lower ends of the guide slits 41S and 42S, an upper limit (top dead center) and a lower limit (bottom dead center) of movement of each auxiliary moving sleeve are defined.

Further, a bifurcated link L is attached to the upper end of the moving rod 42A and the upper end of the outer insertion tube 41A.
Normally, as shown in FIG. 6, the bifurcated link L is in a straight line (that is, the link L1 and the link L2 constituting the bifurcated link are in a straight line), the lower auxiliary moving sleeve 42 is at the top dead center, and the upper auxiliary moving is performed. The sleeve 41 is at a bottom dead center (opened state).
This open state is a cooling mode, which is a mode used during business hours.

  Now, when the operation is performed to pull the bifurcated link L, as shown in FIG. 7, the upper end of the moving rod 42A and the upper end of the outer insertion tube 41A approach each other, the upper auxiliary moving sleeve 41 moves upward, and the lower auxiliary moving sleeve 42 Move down.

Then, the angle of the bifurcated link L gradually decreases, and as shown in FIG. 8, the lower auxiliary moving sleeve 42 reaches the bottom dead center and the upper auxiliary moving sleeve 41 reaches the top dead center (closed state). Become.
This closed state is a cleaning mode, which is a mode used when cleaning after business.
In the closed state, the lower auxiliary moving sleeve 42 is in contact with the bottom surface of the cooling water tank 1, and the upper auxiliary moving sleeve 41 is at a position beyond a certain distance from the water surface of the cooling water tank 1.

As described above, during the cleaning, the antifreeze liquid is divided into an inner region and an outer region with the partition sleeve as a boundary.
By heating the inner region using the heater 5, the inside of the cooling serpentine tube becomes 0 ° or more, so that the inside of the passage can be cleaned in this state.
Even if washing water is flowed, it does not freeze in the cooling serpentine.
Since the antifreeze in the area inside the partition sleeve is only a part of the total antifreeze, it is fast and efficient.
When the cleaning operation is completed successfully, the bifurcated link is operated to return to the cooling mode (see FIG. 6).
As described above, the beer pouring device of the present invention is provided with the partition sleeve 4 and the rod-shaped heater 5 provided inside the partition leave 4, so that a large flow of antifreeze liquid is suppressed when warming in preparation for cleaning. Is done.
Further, when the vertical auxiliary moving sleeves 41 and 42 are moved and the partition sleeve 4 is extended in the vertical direction, the inside of the cooling water tank 1 can be reliably separated into the inner side and the outer side, and a large flow of water can be eliminated.
The heater 5 can quickly heat only the antifreeze liquid in a small and isolated area having a small heat capacity.

FIG. 9 is a schematic diagram for explaining the difference in the volume of the antifreeze liquid before (A) and after (B) isolation for reference.
It can be understood that the volume V2 (after isolation) of the antifreeze liquid after closing is reduced and the heat capacity for heating is reduced compared to the capacity V1 (before isolation) of the antifreeze liquid before closing the partition sleeve 4.

(refrigerator)
Next, the refrigerator is described.
The beer pouring device A is provided with a refrigerator A1, which is a device for cooling the cooling pipe 2 and cooling the antifreeze liquid Y in the cooling water tank at the lower part thereof.
The refrigerator A1 includes a compressor 9 for compressing and supplying a cooling medium to the cooling pipe 2, a radiator (not shown) for radiating the cooling medium compressed and supplied by the compressor 9, and heat radiation using outside air as cooling air. A cooling fan or the like is provided to supply the container.

On the front side of the refrigerator A 1, a connection port 10 is provided in the vicinity of the radiator, which is a part for connecting the beer hose 12 extending from the beer barrel T to the cooling serpentine 3.
By connecting the beer hose 12 connected to the beer barrel T to the connection port 10, the beer flow path between the beer pouring device A and the beer barrel T communicates integrally.
A discharge port for allowing the antifreeze liquid Y in the cooling water tank 1 to flow through a discharge passage (not shown) is provided below the connection port 10.

(Beer cock)
The beer pouring device A is provided with a beer cock 7, and a receiving tray 11 for placing a beer mug is provided below the beer cock 7.
Beer cooled by passing through the cooling serpentine tube 3, for example, beer at −2.5 ° C. to −3 ° C., is poured into a container placed on the tray 11.
That is, a beer that is cooled to less than 0 ° C. (so-called minus beer) can be poured out through the beer cock 7.

  Incidentally, since beer generally contains alcohol, it does not freeze even if the beer is cooled to about minus 3 ° C. If the temperature is lowered to minus 3 ° C, the beer becomes a sherbet. Freezing.

(Temperature controller)
In the beer pouring device A, a temperature controller is attached to the beer cock 7, and the temperature in the beer pouring device A can be visually recognized while operating the beer cock 7.
This temperature controller has a function of adjusting the cooling temperature of beer and performs temperature management of beer poured out from the beer cock 5.

(Refrigerator)
Although Example 1 mentioned above showed in the example where beer pouring device A was placed on a stand and used alone, FIG. 10 shows beer pouring device A placed on refrigeration device B, and The Example 2 connected to the refrigeration apparatus B is shown.

This is a two-stage cooling system in which beer once cooled in the refrigeration apparatus B is sent to the beer pouring apparatus A and further cooled.
A beer barrel T is accommodated in the refrigeration apparatus B, and a carbon dioxide gas cylinder 13 for applying pressure to the beer barrel T and pumping beer is placed outside the beer barrel T.
Incidentally, the lower beer barrel T is a spare stock product used when the upper beer barrel T is empty.
The beer barrel T can be replaced by opening the door of the refrigeration apparatus B.
The upper beer barrel T and the carbon dioxide gas cylinder 13 are connected via a gas hose 14 and are ready for use.

When the beer barrel T is stored in the refrigeration apparatus B, the head T1 to which the beer hose 12 and the gas hose 14 are connected is attached to a fitting base provided at the top of the beer barrel T.
Then, the gas main stopper provided at the tip of the carbon dioxide gas cylinder 13 is opened, the adjustment handle of the pressure regulator 13A is turned, and the pressure of the carbon dioxide gas exiting into the gas hose 14 is adjusted to the temperature of the beer in the beer barrel T (here, The temperature may be adjusted to an appropriate value determined by the set temperature of the refrigerator B).

Now, in order to make the beer pouring device A usable, the handle of the head T1 is operated to open the gas passage in the fitting base of the beer barrel T, and the pressure of the carbon dioxide gas is within the beer barrel T. Set to work on beer.
When the lever of the beer cock 7 is pulled forward in this state, the beer in the beer barrel T flows through the beer hose 12 and the cooling serpentine tube 3 by the pressure of carbon dioxide gas.
And it will be poured from the beer cock 7 into the container mounted on the saucer below.

(Temperature management)
Next, temperature control of the beer pouring device A will be described for reference.
As temperature management of beer pouring device A, temperature management in refrigeration device B which stores beer barrel T, and management of beer pouring temperature by cooling water tank 1 are performed.

The temperature in the refrigeration apparatus B is preferably managed so as to be in a constant temperature state of 4 ° C. or lower.
This is because, when stored at 4 ° C. or lower, active propagation of yeast is suppressed and it is difficult to adhere to the beer hose 12.
Of course, from the viewpoint of economical power costs, the summertime (usually the outside air temperature or room temperature becomes a temperature of 20 ° C. or more at which yeast growth is activated) may be controlled to 10 ° C. or less.

On the other hand, the beer pouring temperature is required to be cooled to a minus temperature in the case of this apparatus.
By keeping the temperature of the antifreeze at a minus temperature lower than 0 ° C., preferably −3 ° C. to −2.5 ° C., the temperature of the beer in the cooling serpentine tube is also cooled to the same temperature and has a unique refreshing feeling. Beer.
When viewed as a whole temperature control, the beer is already cooled below the room temperature (for example, below 4 ° C.) by the refrigeration apparatus B, so that the cooling water tank 1 can be cooled by the antifreeze liquid with relatively little burden.

Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various other modifications are possible without departing from the essence thereof.
The upper auxiliary moving sleeve 41 and the lower auxiliary moving sleeve 42 are extrapolated with respect to the partition sleeve 4, but may be interpolated.

Moreover, in Example 2 mentioned above, although the case where beer was cooled with the refrigeration apparatus B before the beer extraction apparatus A was shown, it connected with another 2nd beer extraction apparatus which cools beer with an antifreeze liquid, and this You may make it pour out from the beer extraction apparatus A of this invention, after letting a beer extraction apparatus pass.
In this case, beer can also be poured out from the second beer pouring device.

The present invention relates to a beer pouring device having excellent cleaning efficiency, and has an advantage that the antifreeze can be efficiently heated before the beer passage is cleaned by partitioning the cooling water tank.
Therefore, as long as this principle is used, the present invention can be widely used for a beverage liquid other than beer, for example, carbonated drinks and juices.
