Abstract

PURPOSE:To eject a beverage in any state at proper temp. in a well foamed state by one apparatus by selecting the cooling degree and vacuum degree of the beverage corresponding to the gas pressure allowed to act on the carbonated beverage in a liquid storage pressure container. CONSTITUTION:A pressure detector 26 detects the gas pressure from a carbon dioxide cylinder 10 and, when the detected value becomes a set value, an opening and closing valve is opened and an opening and closing valve 22 is closed and, contrarily, when said value is lower than the set value, the opening and closing valve 22 is opened and the opening and closing valve 24 is closed. When pressure is set to about 1.3kg/cm<2> in such a case that the temp. of the beer in a draft beer cask 6 is about 10 deg.C, the optimum volume of CO2 can be dissolved in the beer. For example, when the set value of the pressure detector 26 is set to 2.5kg/cm<2>, in such a case that the temp. of the beer in the draft beer cask 6 may be relatively low temp. of 10 deg.C and the pressure of carbon dioxide may be also low, the opening and closing valve 22 is opened and the opening and closing valve 24 is closed. When the first ejecting cock 21 is opened, the beer in the draft beer cask 6 passes through the opening and closing valve 22 from a beer conduit 5 to be supplied to the first cooling pipe 19 and is ejected from the first ejecting cock 21. Therefore, draft beer can be serviced at a proper temp. in a proper foamed state.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a dispensing device for dispensing sparkling beverages such as carbonated beverages and draft beer, and particularly relates to a dispensing device for dispensing sparkling beverages such as carbonated beverages and draft beer, and particularly for dispensing sparkling beverages such as carbonated beverages and draft beer by gas pressure from a beverage supply source such as a draft beer barrel. This invention relates to a device that can press out a sparkling beverage, reduce the pressure appropriately, and pour it out at an appropriate temperature.

The beverage in the present invention is a sparkling beverage such as a carbonated beverage or draft beer, but to simplify the explanation, the prior art and the embodiments of the invention will be explained using draft beer as an example.

(Prior Art) A device as shown in FIG. 23 is known as a device for pouring draft beer from a draft beer barrel into a mug or the like. That is, one end of the cooling pipe 3 disposed in the cooling water 2 in the main body 1 is connected to the spout cock 4, which is a spout, and the other end is connected to the spout cock 4.
It is connected to the outside beer conduit 5. A dispense head 8 is attached to the take-out lower part of the draft beer barrel 6, which is a liquid storage pressure vessel, and the upper part of the dispense head 8 is connected to the beer conduit 5 through a joint 9. Further, a pressure reducing valve 11 attached to a carbon dioxide gas cylinder 10 which is a gas supply source is connected to a dispensing head 8 via a gas conduit 12.
It is connected to the gas inlet 13, which is a convex portion of the gas inlet 13. Furthermore, the cooling water 2 is cooled by a refrigeration mechanism 14, and a part of the cooling water 2 becomes ice (not shown) and is stored in a certain amount.

In order to pour out draft beer in the above device, a pressure reducing valve 11 is used.
If the carbon dioxide gas in the carbon dioxide gas cylinder 10 is introduced into the draft beer barrel 6 from the gas inlet 13 of the dispense head 8 by setting the pressure to a predetermined pressure, the draft beer in the rod will flow through the siphon pipe (not shown) due to this gas pressure. is supplied to the cooling pipe 3 through the conduit 5, and by opening the spout cock 4,
Container 1, such as a mug, is cooled by heat exchange with cooling water 2
It is poured out at 5.

By the way, during this pouring, it is preferable to generate a predetermined amount of fine, fairly creamy foam, which greatly affects the flavor of the draft beer. This foaming is related to carbon dioxide pressure at the time of pouring, beverage temperature, pouring speed, etc.
The amount of CO2 gas volume dissolved in a sparkling beverage such as draft beer is determined by the beverage temperature and pressure. In other words, when the pressure of carbon dioxide gas acting on the beverage is constant, the higher the beverage temperature is, the smaller the volume of CO2 gas that can dissolve in the beverage, making it easier to foam. It's easy to do.

Therefore, it is necessary to apply carbon dioxide gas pressure in the rod according to the temperature of the beverage. The higher the temperature of the beverage, the higher this pressure needs to be; if it is too low, it will not be able to suppress the carbon dioxide gas liberated from the beverage, resulting in so-called vented beer, and if it is too high, the volume of CO2 gas will be excessive. Also, since the dispensing speed becomes faster, more bubbles are produced when dispensing.

(Problem to be Solved by the Invention) However, as shown in Fig. 23, the conventional pouring device maintains a constant cooling degree and reduced pressure regardless of the carbon dioxide pressure in the draft beer barrel 6, the beverage temperature, or the CO2 gas volume dissolved in the beverage. Since the carbon dioxide gas pressure acting on the beverage is high, the pouring speed becomes faster and the time the beverage passes through the cooling pipe 3 becomes shorter, resulting in less heat exchange with the cooling water 2 and insufficient cooling. Conversely, if the pressure is low, the pouring speed will be slow and overcooling will occur. In other words, when pouring out draft beer from a draft beer barrel that has been left in an outside temperature of 30 degrees Celsius or higher for a long time, such as in the summer, high pressure is applied, resulting in insufficient cooling; The problem was that it would get too cold when served.

In addition, in recent years, sales of draft beer with a high dissolved rate of CO2 gas volume (hereinafter referred to as high acidity) have become active, and in order to pour out this draft beer, the pressure of carbon dioxide gas applied to the beverage must be higher than that of conventional draft beer. It is necessary to suppress the foaming of carbon dioxide gas liberated from the beverage, and therefore, the above-mentioned problem of insufficient cooling occurs and good pouring is not possible.

The present invention was made from this point of view, and its purpose is to control the carbon dioxide pressure applied to sparkling beverages, the beverage temperature in the liquid storage pressure container, and the CO2 gas volume dissolved in the beverage, even though it is a single device. To provide a sparkling beverage dispensing device capable of pouring out a sparkling beverage at an appropriate temperature and with good foaming regardless of the temperature.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the sparkling beverage dispensing device of the present invention includes a liquid storage pressure vessel containing a sparkling beverage, a gas supply source, and a gas supply source. A pressure adjustment mechanism that adjusts the gas pressure supplied from the supply source and supplies it to the sparkling beverage in the liquid storage pressure vessel, a cooling water tank, a plurality of cooling pipes arranged in the cooling water tank, and a cooling water tank. It is equipped with at least one spout provided outside and a selection means for selecting one of the plurality of cooling pipes according to the gas pressure supplied to the sparkling beverage, and the selection means selects one of the plurality of cooling pipes according to the gas pressure supplied to the sparkling beverage. It is characterized by supplying the sparkling beverage to the cooling pipe and pouring it out from the spout. In addition, the pressure regulation mechanism is implemented with a general pressure regulation valve (pressure reducing valve) that artificially regulates the pressure, and also includes a pressure control valve with a heat sensitive body, and the temperature in the liquid storage pressure vessel is increased by the thermal signal of the heat sensitive body. The gas pressure supplied to the sparkling beverage may be automatically adjusted.

It also has a liquid storage pressure vessel containing a sparkling beverage, a gas supply source, and a heat sensitive body, and upon receiving a thermal signal from the heat sensitive body, gas pressure is supplied from the gas supply source to the sparkling beverage in the liquid storage pressure vessel. A pressure control valve that automatically adjusts, a cooling water tank, at least one cooling pipe disposed within the cooling water tank, at least one spout provided outside the cooling water tank, and a pressure control valve. A sparkling beverage dispenser comprising a selection means for communicating or blocking a cooling pipe according to the adjusted gas pressure, and supplying the sparkling beverage to the cooling pipe selected by the selection means and pouring it out from the spout. It can also be a device. In either case, the selection means may be a switching valve device that can switch based on a signal from the gas pressure supplied to the sparkling beverage, or a spout that can be selected based on a signal from the gas pressure supplied to the sparkling beverage. .

(Function) By passing the sparkling beverage through a cooling pipe that corresponds to the gas pressure supplied to the sparkling beverage in the liquid storage pressure vessel, the sparkling beverage can be cooled in just the right amount.

(Example) Hereinafter, a first example of the present invention will be described with reference to FIG. Note that the same parts as those shown in FIG. 23 are given the same numbers and the explanation thereof will be omitted. Cooling water 18 is stored in a cooling water tank 17 of the main body 16, and a first cooling pipe 19 and a second cooling pipe 20 are provided as cooling flow passages having different lengths, diameters, piping resistances, and heat exchange areas. has been done.

The first cooling pipe 19 has a small pipe resistance and heat exchange area, and the second cooling pipe 20 has a large pipe resistance and a heat exchange area. One end of the first cooling pipe 19 is connected to a first spout 21 that is a spout, the other end is connected to an on-off valve 22, and one end of the second cooling pipe 20 is connected to a second spout that is a spout.
It is connected to the spout 23 and the other end is connected to the on-off valve 24. Also, this on-off valve 22 and on-off valve 24, which are switching valve devices,
is connected to a beer conduit 5 as a supply pipe on the upstream side (hereinafter referred to as upstream side) with respect to the flow direction of the beverage. A pressure reducing valve 11 which is a pressure regulating mechanism attached to a carbon dioxide gas cylinder 10 which is a gas supply source is connected to a pressure detector 26 in the main body 16 via a first gas conduit 25, and this pressure detector 26 is connected to a pressure detector 26 inside the main body 16. It is connected to the gas inlet 13 of the dispense head 8 via a two-gas conduit 27 . This pressure detector 26 is electrically connected to the on-off valve 22 and the on-off valve 24, and is connected to the carbon dioxide cylinder 10 via the pressure reducing valve 11.
Detects the pressure of carbon dioxide gas supplied from the sensor, and when the value exceeds a certain set value, the on-off valve 24 opens and the on-off valve 22 closes, and conversely, when it is lower than the set value, the on-off valve 22 opens and the on-off valve 24 closes. is being done. In other words, this is the selection means. Since this is an existing technology, detailed explanation will be omitted.

Next, the operation of this device will be explained. First, to dispense beer, the dispense head 8 is connected to the draft beer barrel 6, and carbon dioxide pressure is applied to the draft beer barrel 6. As mentioned above, this carbon dioxide pressure needs to be set according to the beer temperature in the draft beer barrel 6, and for example, if this temperature is 10°C.
If it is around 1.3kg depending on the type of beer
By setting the pressure around /cd, the CO is optimal for beer.
2 gas volumes can be dissolved.

By the way, the setting value of the pressure detector 26 mentioned above is set to 2, for example.
．． 5) cg/c-, when the beer temperature in the draft beer barrel 6 is relatively low at 10° C. and the carbon dioxide pressure is low, the on-off valve 22 opens and the on-off valve 24 closes. Therefore, when the first pouring pot 21 is opened, the beer in the draft beer barrel 6 is supplied from the draft beer barrel 6 through the on-off valve 22 to the first cooling pipe 19, and from the first pouring pot 21 to a mug (not shown), etc. Pours out (cannot be poured from the second pouring pot 23)
.

At this time, the beer flows through the first cooling pipe 19, which has a smaller piping resistance and heat exchange area than the second cooling pipe 20, so it is not only cooled from around 10°C to around 7°C, which is suitable for drinking, but also
．． The pressure is reduced from around 3 kg/c to a pressure that can be easily poured out. Therefore, draft beer can be provided at an appropriate temperature and foaming without causing problems such as overcooling or slow pouring speed.

However, when pouring beer from the draft beer barrel 6, which has been heated to a high temperature close to 30 degrees Celsius, such as during the summer when the outside temperature is high, a carbon dioxide pressure of around 1.3) cg/C- is suitable for beer. Since it is not possible to keep the CO2 gas volume dissolved and the so-called venting results in beer, it is necessary to apply a pressure of around 3.2 kg/c-, depending on the type of beer. Therefore, the pressure detector 26
If the set value is 2.5 kg/c-, the on-off valve 22 is closed and the on-off valve 24 is opened. Then, when the second pouring pot 23 is opened, the beer in the draft beer barrel 6 is supplied from the beer conduit 5 through the on-off valve 24 to the second cooling pipe 20, and is poured out from the second pouring pot 23 into a mug (not shown) or the like. It will be done. It is not poured from the first pouring pot 21.

At this time, the beer flows through the second cooling pipe 20, which has a large piping resistance and heat exchange area, and through this second cooling pipe 20, beer at around 30°C is cooled to around 7°C and from a pressure of around 3.2 kg/c-. As long as the length and diameter are such that the pressure can be reduced to a pressure that allows easy pouring, beer can be poured under conditions similar to beer at 10° C., as described above.

Therefore, beer can be poured into a mug or the like in good condition without problems such as insufficient cooling or fast pouring speed.

Furthermore, when pouring out highly carbonated beer, it is necessary to apply a higher carbon dioxide pressure than conventional draft beer, as described above. For example, when the beer temperature in the draft beer barrel 6 is around 30°C, the carbon dioxide pressure to dissolve the optimal CO2 gas volume in beer is around 3.2 kg / c- for conventional beer. For highly carbonated beers, it should be around 3.5 kg/cd.

Therefore, for example, the set value of the pressure detector 26 is set to 3.4 kg/
cJ, when the beer temperature in the draft beer barrel 6 rises to around 30°C in the summer, etc., if the beer is conventional beer, it will be poured out from the first pouring port 21 via the first cooling pipe 19, If it is a highly carbonated beer, it can also be used for the purpose of pouring out from the second spout 23 via the second pouring pipe 20.

Further, for example, when dispensing is performed using the first dispensing pot 21, the second dispensing pot 23 may be removed and the stopper may be closed with a lid (not shown) instead.

When dispensing is performed on the second cooling pipe 20 side, the first dispensing pot 21 and the lid may be replaced. At this time, a second pouring pot 23 may be prepared, but from a cost perspective, the first pouring pot 23 may be prepared.
It is better to use the pouring pot 21 instead.

FIG. 2 shows a second embodiment of the present invention, in which one end of the first cooling pipe 19 is connected to an on-off valve 22, and the other end of the first cooling pipe 19 is connected via an on-off valve 28 to a spout cock 29, which is a spout. , and one end of the second cooling pipe 20 is connected to the on-off valve 24, and the other end is connected to the pouring cock 29 via the on-off valve 30, and the pressure detector 26 is connected to the on-off valve 22, which is a switching valve device. .2
4゜28.30 as a selection means, when the carbon dioxide pressure exceeds the set value, the on-off valve 24 and the on-off valve 30 open, and the on-off valve 22 and the on-off valve 28 close, and vice versa. The on-off valve 22 and the on-off valve 28 are opened, and the on-off valve 24 and the on-off valve 30 are closed.

Other details are the same as in FIG.

The operation of this device is such that when the carbon dioxide pressure applied to the beer in the draft beer barrel 6 is lower than the set value of the pressure detector 26, the beer passes from the draft beer barrel 6 through the beer conduit 5 and the on-off valve 22 and increases the piping resistance. It is supplied to the first cooling pipe 19 with a small heat exchange area, and is supplied to the pouring cock 2 via the on-off valve 28.
9, so it can be poured out without being supercooled. Conversely, if the carbon dioxide pressure applied to the beer in the draft beer barrel is higher than the set value of the pressure detector 26, the beer will be poured out due to piping resistance and heat exchange area. Since it is sufficiently cooled through the large second cooling pipe 20, the problem of insufficient cooling can be overcome and good pouring can be achieved. According to the second embodiment, there is only one pouring cock 29 compared to the first embodiment, so the problem of incorrect selection of the pouring cock does not occur.

3 and 4 show a third embodiment of the present invention, in which three boats of a three-way valve 31, which is a switching valve device, are connected to a first cooling pipe 19, a second cooling pipe 20, and a beer conduit 5, respectively. The three-way valve 31 is electrically connected to the pressure detector 26 and serves as a selection means to connect the beer conduit 5 and the first cooling pipe 19 as shown in FIG. 4(a) when the carbon dioxide pressure is lower than the set value. On the other hand, when the temperature exceeds the set value, the beer conduit 5 and the second cooling pipe 20 are brought into communication as shown in FIG. 4(b). , the other details are the same as in FIG.

The function of this device is similar to the above-mentioned embodiment, by selecting whether to flow the beer into the first cooling pipe 19 or the second cooling pipe 20 according to the carbon dioxide pressure acting on the beer in the draft beer barrel 6. Since the number of valves is reduced compared to the first embodiment, it is advantageous in terms of cost and miniaturization of the device.

5 and 6 show a fourth embodiment of the present invention, in which a three-way valve 31 is provided in place of the on-off valves 22 and 24 in FIG. 2, and a three-way valve 32 is provided in place of the on-off valves 28 and 30. , are electrically connected to the pressure detector 26, and as a selection means, when the carbon dioxide pressure is lower than the set value, the beer conduit 5, the first cooling pipe 19, and the pouring cock 29 are connected as shown in FIG. 6(a). On the other hand, when the temperature exceeds the set value, the beer conduit 5, the second cooling pipe 20, and the pouring cock 29 are in communication as shown in FIG. 6(b). The rest is the same as in FIG. 2.

The operation of this device is similar to that of the previous embodiment, and since there is only one pouring cock, there is no possibility of incorrect selection.

Further, in the above-mentioned embodiment, there are two cooling pipes, but the cooling pipes are not limited to this, and three or more cooling pipes may be provided as shown in FIG. In FIG. 7, the first cooling pipe 33
, a second cooling pipe 34, and a 'JN3 cooling pipe 35 are disposed in the cooling water 18, and each end is connected to an on-off valve 36, a first outlet pot 37, an on-off valve 38, a second outlet pot 39, and an on-off valve. 4
0 and the third spout 41. The first cooling pipe 33, the second cooling pipe 34, and the third cooling pipe 35 have different piping resistance, heat exchange area, etc. The tube 35 is designed to be larger. Further, the pressure detector 26 is electrically connected to an on-off valve 36°38.40 which is a switching valve device, and is used as a selection means to determine whether the pressure applied to the beer in the draft beer barrel 6 is lower than the first set value P1. and on-off valve 36
opens and the on-off valve 38.40 closes, and when the first set value is greater than or equal to 21 and less than the second set value P2, the on-off valve 38 opens and the on-off valve 36.40 closes, and from the second set value P2. When the temperature rises, the on-off valve 40 opens and the on-off valves 36 and 38 close. Other details are the same as in Figure 1, but better quality control is achieved by subdividing the switching based on carbon dioxide pressure.
The advantage is that better pouring can be expected.

FIG. 8 shows a type in which the three spout cocks in FIG. 7 are combined into one, and both ends of the first cooling pipe 33 are connected to on-off valves
and the on-off valve 42 , both ends of the second cooling pipe 34 are connected to the on-off valve 38 and the on-off valve 43 , and the third cooling pipe 35 is connected to the on-off valve 43 .
Both ends are connected to an on-off valve 40 and an on-off valve 44. Also, on-off valves 42, 43, and 44, which are switching valve devices, are connected to a pouring cock 45 on the downstream side. In this case, on-off valve 3
6, on-off valve 42, on-off valve 38, on-off valve 43, on-off valve 40
The opening/closing valve 44 is made to operate in conjunction with the opening/closing valve 44, and the other features are the same as those shown in FIG. 7, but since there is only one pouring cock 45, there is an advantage that mistakes in selection of the pouring cock are eliminated.

By the way, in the embodiments described so far, the pressure detector 26
is located between the pressure reducing valve 11 and the gas inlet 13 of the dispense head 8, and was used to detect the carbon dioxide pressure before entering the draft beer barrel 6. However, as shown in FIG. The gas pressure may be detected, or it may be provided outside the main body, although not shown.

Furthermore, as shown in FIG. 10, the display effect can be improved by displaying the pressure detected by the pressure detector 26 on the front of the device on the display board 46.

In addition, as shown in FIGS. 11 to 13, the first cooling pipe 47
A second cooling pipe 48 having a larger piping resistance and heat exchange area than the first cooling pipe 47 is connected to the beer conduit 5 on the upstream side, and the downstream side of the first cooling pipe 47 is connected to the first pouring pot 49. Connect the downstream side of the second cooling pipe 48 to the second pouring pot 50
The same effect as in the first embodiment can be expected by simply connecting it to . That is, the pressure reducing valve 51, which is a pressure regulating mechanism, is normally
As shown in Figure 3, the pressure of carbon dioxide gas from the carbon dioxide gas cylinder 10 is reduced to a predetermined pressure by turning the center handle and aligning the arrow on the handle with the scale on the outside. Depending on whether the water is higher or lower (as shown in FIG. 12), whether to pour from the first pouring pot 49 or from the second pouring pot 50 is selected as shown in FIG. Therefore, the selection means in this case is a spout such as the first spout 49 or the second spout 50.

By the way, in the above-mentioned embodiment, the pressure reducing valve 11.51 was used as the pressure regulating mechanism, but as the pressure regulating mechanism, a heat sensitive body 52 for detecting the temperature of the object to be detected as shown in FIGS. 14 to 16 may be used. By using the pressure control valve 53 that is automatically controlled by the pressure control valve 53, optimal dispensing can be achieved almost automatically. FIG. 14 shows the case where the heat sensitive body 52 is closely attached to the lower surface of the draft beer barrel 6, and FIG.
2 is attached to the upper surface of the barrel holder 54 for receiving the draft beer barrel 6 so that it is brought into close contact with the draft beer barrel 6 by means of a spring (not shown). This shows the case where they are integrated.In either case,
Even if the temperature of the object to be detected (the beer in the draft beer barrel 6 in FIGS. 14 and 15, and the outside air in FIG. 16) changes, the carbon dioxide gas cylinder 10 supplies the gas to the pressure detector 26 in response to the changed temperature. Since the carbon dioxide pressure changes automatically, the amount of change can be set to be optimal depending on the type of beer in the draft beer barrel 6 (for example, conventional beer or beer with high acidity). As in the first embodiment, good pouring is possible without requiring specialized skills. By the way, in FIG. 16, the heat sensitive element 52 is exposed to the outside air and the pressure control valve 53 is controlled by this outside temperature, but this means that if the draft beer barrel 6 is left in the outside air for a certain period of time, the beer inside will naturally reach the outside temperature. This is due to the fact that the temperature rises or falls, and that the beer in the beer conduit 5 is easily influenced by the outside temperature.

Further, although the pressure control valve 53 is provided adjacent to the carbon dioxide gas cylinder 10 in FIGS. 14 to 16, the pressure control valve 53 is not limited thereto, and may be incorporated into the main body 55 as shown in FIG. 17. In this case, the constant pressure valve 56 is connected to the carbon dioxide gas cylinder 10 and the first
Pressure inside the gas pipe 25! It is preferable to keep the carbon dioxide gas pressure supplied to I+ Mii 53 at about 4 to 5 kg/c. In addition, in FIG. 17, the temperature of the beer in the draft beer barrel 6 before it is heat-exchanged with the cooling water 18 is detected by placing the heat-sensitive element 52 in close contact with the conduit between the draft beer conduit 5 and the on-off valve 22°240. The on-off valves 22 and 24 are switched. In this case, the appearance will be the same as in Figure 1, so it will have a clean shape.

Furthermore, even if the pressure control valve 53 is incorporated into the main body 55 as shown in FIG. 17, the heat sensitive element 52 may be provided to detect the temperature of the draft beer barrel 6 or the outside air as shown in FIGS. 14 to 16. It is possible to implement the method as shown in FIG. 18. In FIG. 18, the pressure of carbon dioxide gas supplied from the carbon dioxide gas cylinder 10 via a constant pressure valve 56 is controlled by a pressure control valve 3 controlled by a heat sensitive element 52 that is in close contact with the bottom surface of the draft beer barrel 6 within the barrel pedestal 54. The pressure sensor 26 detects the adjusted carbon dioxide pressure and opens the on-off valve 22.2.
4 switching is being performed.

By the way, FIGS. 14 to 18 show the first embodiment (first embodiment).
Although the explanation has been based on the switching of the on-off valves 22 and 24 in Fig.
It is clear that the present invention can also be implemented by switching a switching valve device such as an on-off valve as explained in FIG.

Furthermore, if there are multiple pouring cocks, installing lamps etc. around the pouring cocks and lighting lamps etc. near the spouting cocks that can be used for pouring can be done to avoid mistakes in the selection of the spouting cock. will disappear. FIG. 19 shows an example in which this is applied to the first embodiment, and a lamp 57 is provided above the first pouring pot 21, and a lamp 58 is provided above the second pouring pot 23.
When valve 2 is open, lamp 57 is turned on and lamp 58 is turned off, and when valve 24 is open, lamp 58 is turned on and lamp 57 is turned off.

20 and 21 show another embodiment of the present invention, in which a main cooling pipe 59 and an auxiliary cooling pipe 60 are provided in the cooling water 18, and a pressure detector 26 and a switching valve device are provided in the main body 61. A four-way valve 62 is provided. The four boats of the four-way valve 62 are connected to the other end of the main cooling pipe 59, one end of which is connected to the pouring pipe 3, both ends of the cooling pipe 60, and a pipe line that communicates with the beer conduit 5 outside the main body 61. and is connected to. Further, the pressure detector 26 is electrically connected to a four-way valve 62, and beer in the draft beer barrel 6 is supplied from the carbon dioxide gas cylinder 10 via a pressure control valve 53 that uses a heat sensitive element 52 as a selection means. If the carbon dioxide pressure is detected and the value is lower than a certain set value, the four-way valve 62 will be in the position shown in FIG. 21(a), and conversely, if it is higher than the set value, the four-way valve 62 will be in the position shown in FIG. It is made so that.

The operation of this device can be seen, for example, in the example of Wang Rikkyader! If the setting value of 26 is 2.5 kg/cd, the beer temperature in the draft beer barrel 6 is low and the carbon dioxide pressure acting on this beer is 2.5 kg/cd.
When the weight is lower than 5 kg/c+1, the four-way valve 62 is operated as shown in Fig. 21 (
Since the position is a), when the pouring hole 63 is opened, the beer in the draft beer barrel 6 is supplied from the beer conduit 5 to the main cooling pipe 59 without passing through the auxiliary cooling pipe 60, and from the pouring hole 3 to the main cooling pipe 59 (not shown). It is poured into jotsuki etc. At this time, since the beer does not flow through the auxiliary cooling pipe 60, it is poured out with a small degree of cooling and a small degree of pressure reduction, and problems such as overcooling or slow pouring speed do not occur. Conversely, if the temperature of the beer in the draft beer barrel 6 is high and the pressure acting on the beer is 2.5 kg/cd or more, the four-way valve 62 will be in the position shown in FIG. When opened, the beer in the draft beer barrel 6 flows from the beer conduit 5 through the auxiliary cooling pipe 60 to the main cooling pipe 59.
It is then poured from the pouring cup 3 into a jug (not shown) or the like. At this time, the beer is poured with a large degree of cooling and a large degree of reduced pressure, so problems such as insufficient cooling and fast pouring speed do not occur (good pouring is possible).

FIG. 22 shows still another embodiment of the present invention, in which a cooling pipe 64 is disposed in the cooling water 18, one end of this cooling pipe 64 communicates with the beer conduit 5, and the other end branches off into a first pipe. cooling pipe 6
5 and a second cooling pipe 66 having a larger piping resistance and heat exchange area than the first cooling pipe 65. Also, the first cooling pipe 6
The downstream side of the second cooling pipe 66 is connected to the first spout 8 via an on-off valve 67, and the downstream side of the second cooling pipe 66 is connected to a second spout 70 via an on-off valve 69. Also, the on-off valves 67 and 69, which are switching valve devices, are electrically connected to the pressure detector 26 as in the previous embodiment, and the pressure inside the draft beer barrel 6 is controlled via the pressure control valve 53 having a heat sensitive body 52 as a selection means. When the carbon dioxide pressure acting on the beer is lower than the set value, the on-off valve 67 is opened and the on-off valve 69 is closed, and conversely, when it is higher than the set value, the on-off valve 69 is opened and the on-off valve 67 is closed. .

The operation in this embodiment is similar to the previous embodiment, in which the cooling pipe is selected according to the carbon dioxide pressure, and the cooling degree suitable for the beer is adjusted.
Pouring is possible at reduced pressure. Although two pouring cocks are provided in this embodiment, it is possible to connect the downstream sides of the on-off valves 67 and 69 and pouring from one pouring cock, or conversely, increase the number of branches and pour more Of course, changes such as pouring from a tap are possible.

In addition, in FIGS. 20 to 22, the positions of the heat sensitive element 52 and the pressure control valve 53 are set as shown in FIG. 14 to detect beer temperature in the draft beer barrel 6, but as shown in FIGS. 15 to 18, It can be carried out in any positional relationship.

As described above, it goes without saying that the present invention can be implemented in various ways without departing from the spirit thereof.

[Effects of the Invention] As explained above, if the dispensing device of the present invention is used, the degree of cooling and depressurization of the beverage can be selected depending on the gas pressure applied to the foamed beverage in the liquid storage pressure container. Therefore, although it is a single device, it is possible to pour out beverages in any condition with good foaming and at an appropriate temperature.
