Abstract

PURPOSE:To enable brewage to be discharged at a proper temperature and under superior bubbling conditions by a method wherein an end part or a mid-way part of a cooling pipe is provided with a flow metering valve of which a metering amount is automatically adjusted in correspondence to a gas pressure acting against brewages contained in a liquid containing pressure container with a pressure adjusting mechanism. CONSTITUTION:One end of a cooling pipe 16 arranged in a cooling water 2 is connected to a brewage inlet 18 of a flow metering valve 17 and the other end is connected to a dispensing head 8 fixed to a draft beer barrel 6 through a conduit 5. In order to feed beer, a pressure reducing valve 11 is operated to act a pressure of carbon dioxide gas from a bomb 10 to a draft beer barrel 6. this pressure is set in correspondence with a beer temperature within the draft beer barrel 6. For example, in case that a surrounding air shows a high temperature in summer season or the like and beer in the draft beer barrel 6 of which temperature is increased up to a high temperature of about 30 deg.C is to be fed out, a pressure of carbon dioxide gas is increased, resulting in that a pressure to be supplied to a pressurizing port 22 of the flow metering valve 17 is increased and a valve 25 is pushed down against a pushing-up force of a spring 26. Accordingly, the beer is metered in a brewage passage 28 and its flowing speed is reduced, so that the beer can be fed out into a mug or the like under a superior condition without any lack of cooling amount.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a beverage dispensing device, and in particular, a beverage dispensing device for cooling and cooling a beverage in a liquid storage pressure container by force-feeding it to a cooling pipe using gas pressure. This relates to a device that enables pouring at a reduced pressure and at an appropriate temperature.

Beverages in the present invention include juices, wine, carbonated drinks,
Although the type of draft beer does not matter, the prior art and the embodiments of the invention will be described using draft beer as an example.

(Prior Art) As a device for dispensing draft beer from a draft beer barrel into a mug or the like, the one shown in FIG. 27 is known. In FIG. 27, cooling pipe 3 disposed in cooling water 2 in main body 1
One end is connected to a pouring cock 4 which is a spout, and the other end is connected to a beer conduit 5 outside the main body 1. Further, a dispensing 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 dispensing head 8 is connected to the beer conduit 5 through a joint 9. Further, 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 gas inlet 13 which is a convex portion of the dispensing head 8 via a gas conduit 12. Further, the cooling water 2 is cooled by a refrigeration mechanism 14, and a certain amount of ice (-) is stored as ice (not shown).

Therefore, in order to pour out draft beer, first, the pressure reducing valve 11 is set to a predetermined pressure, and the carbon dioxide gas in the carbon dioxide gas cylinder 10 is introduced into the draft beer barrel 6 through the gas inlet 13 of the dispensing head 8.
to be introduced within. As a result, the draft beer in the draft beer barrel 6 is supplied to the cooling pipe 3 from a siphon pipe (not shown) through the beer conduit 5 by gas pressure, and by opening the pouring cock 4, heat exchange is performed with the cooling water 2. The liquid is cooled and poured into a container 15 such as a mug.

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 carbon dioxide pressure acting on the beverage is constant, the higher the beverage temperature is, the smaller the volume of CO2 gas that can be dissolved in the beverage, making it easier to foam, and the faster the pouring speed is, the greater the degree of fluidity or stirring of the beverage. The easier it is to foam. Therefore, the carbon dioxide pressure according to the beverage temperature is adjusted to the draft beer barrel 6.
You need to add it inside. 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 released from the beverage and the so-called air will become beer, and if it is too high, the 002 gas volume 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. 27, 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 beverage is poured at a high temperature, if the carbon dioxide gas pressure acting on the beverage is high, the pouring speed becomes faster and the time the beverage takes to pass 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. That is, for example, when pouring out the draft beer in the draft beer barrel 6 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 disadvantage of pouring it out is that it gets too cold.

In addition, in recent years, sales of draft beer with a high dissolved rate of CO2 gas volume (hereinafter referred to as high acid content) 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, resulting in the problem of insufficient cooling as described above, making it impossible to pour out the beverage properly.

The present invention was made from this point of view, and its purpose is to control the gas pressure that acts on the beverage, the beverage temperature in the liquid storage pressure container, or the gas volume dissolved in the beverage, even though it is a single device. To provide a beverage dispensing device capable of dispensing a beverage at an appropriate temperature and with good foaming regardless of the conditions.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention provides a liquid storage pressure vessel containing a beverage, a gas supply source, and a gas pressure supplied from the gas supply source. A pressure adjustment mechanism that adjusts the temperature and acts on the beverage in the liquid storage pressure vessel, a cooling pipe that circulates and cools the beverage taken out from the liquid storage pressure vessel, a spout that pours out this beverage, and a cooling pipe that It is characterized by comprising a throttle valve which is provided at the end or in the middle and whose throttle amount is automatically adjusted according to the gas pressure acting on the beverage in the liquid storage pressure container by means of a pressure adjustment mechanism, and A liquid storage pressure vessel containing a beverage, a gas supply source, a pressure adjustment mechanism that adjusts the gas pressure supplied from the gas supply source to act on the beverage in the liquid storage container, and a liquid storage pressure vessel taken out from the liquid storage pressure vessel. A cooling pipe that circulates and cools the beverage, a spout that pours out the beverage, a throttle valve provided at the end or midway of the cooling pipe, and a throttle valve that acts on the beverage in the liquid storage pressure vessel. The throttle valve is characterized by comprising a throttle means that is operated manually or automatically to adjust the throttle amount of the throttle valve in accordance with the gas pressure to be applied. Further, the throttle means may consist of a pressure transducer that detects the gas pressure acting on the beverage in the storage pressure container, and an actuation device that operates the throttle valve based on a signal from the pressure transducer. It may consist of a display device that displays the gas pressure applied to the beverage in the liquid pressure container, an actuation device that operates the throttle valve, and an operation section that controls the actuation device based on the signal from the display device. A pressure transducer that detects the gas pressure applied to the beverage in the liquid storage pressure container, a display that displays the gas pressure detected by the pressure transducer, an actuator that operates the throttle valve, and a signal from the display device. It may also include an operating section for controlling the actuating device. In addition to being implemented with a general pressure regulating valve that artificially adjusts the pressure, the pressure regulating mechanism also includes a heat sensitive part and a gas pressure that is applied to the beverage in the liquid storage pressure container based on the heat sensitive signal of the heat sensitive part. It may also consist of a pressure control valve that automatically adjusts the pressure.

(Function) By using the throttle valve and the throttle means, the beverage can be supplied at a predetermined pouring speed even if the gas pressure acting on the liquid storage pressure container is high or low.

(Example) Hereinafter, a first example of the present invention will be described based on FIGS. 1 to 4. One end of the cooling pipe 16 disposed in the cooling water 2 is connected to a drinking port 18 of a throttle valve 17, and the other end is connected to a dispense head attached to a draft beer barrel 6, which is a liquid storage pressure vessel, via a beer conduit 5. 8 is connected. Further, the downstream side of the Garo conduit 19, which is connected to the carbon dioxide gas cylinder 10 which is a gas supply source via a pressure reducing valve 11 which is a pressure adjustment mechanism, is branched into a first gas conduit 20 and a second gas conduit 21. , the first gas conduit 20 is connected to the dispense head 8;
Further, the second gas conduit 21 is connected to a pressurizing port 22 of the throttle valve 17. Furthermore, the beverage outlet 23 of the throttle valve 17 is connected to the pouring cock 4, which is a spout.

As shown in FIG. 3, the throttle valve 17 has a drinking capacity of 18.
Beverage outlet 23. It is composed of a main body 24 having a pressurizing port 22, a valve 25 provided in the main body 24, and a spring 26, and receives the carbon dioxide pressure supplied to the pressurizing port 22 on a pressure receiving surface 27 of the valve 25. This allows the valve 25 to move up and down. That is, when the gas pressure supplied to the pressurizing port 22 is relatively low, the valve 25 is located at the position shown in FIG. It is pushed down against the push-up blade and reaches the position shown in FIG.

At this time, when the valve 25 is lowered, the beverage flow path 28 is restricted. Further, the valve 25 is formed with a stepped portion 25a, and this stepped portion 25a acts as a stopper to prevent the valve 25 from descending by a predetermined amount or more (even if the beverage flow path 28 is throttled, the minimum clearance is (to be maintained)

In order to pour out beer, the pressure reducing valve 11 is operated to apply carbon dioxide pressure from the carbon dioxide gas cylinder 10 to the draft beer barrel 6. This carbon dioxide pressure needs to be set according to the beer temperature in the draft beer barrel 6, as described above.

For example, in winter, when the beer temperature in the draft beer barrel 6 is relatively low and the carbon dioxide pressure is low, the carbon dioxide pressure supplied to the pressurizing port 22 of the throttle valve 17 will also be low. When the cock 4 is opened, the beer in the draft beer barrel 6 flows from the beer conduit 5 to the cooling pipe 16. Beverage channel 2 of throttle valve 17
8 and is poured out from the pouring cock 4 into a jug (not shown) or the like. At this time, the beer is not squeezed much in the beverage flow path 28, so there is no problem of slow pouring speed, and since the time for heat exchange with the cooling water 2 is shortened, the beer is kept at an appropriate temperature without overcooling. In addition, draft beer can be served with foam. Also, at this time, gas and beer flow as shown in the block diagram of FIG.

However, when the outside temperature is high such as in the summer and the beer in the draft beer barrel 6 is to be poured out at a temperature close to 30 degrees Celsius, the carbon dioxide pressure must be increased to dissolve the appropriate volume of Co2 gas for the beer. Must be. Therefore, the pressure of carbon dioxide gas supplied to the pressurizing port 22 of the throttle valve 17 increases, and the valve 25 is pushed down against the push-up blade of the spring 26. Therefore, the beer is squeezed in the beverage flow path 28 and the flow rate is reduced, so the problem of high pouring speed does not occur, and the time for heat exchange with the cooling water 2 is longer than before, resulting in insufficient cooling. Beer can be poured into a mug or the like in good condition without any problems.

It should be noted that the present invention is not limited to the above-described one embodiment, and the present invention is not limited to the first embodiment.
In place of the throttle valve 17 used in the figure, a throttle valve 29 as shown in FIG. 5 or a throttle valve 30 as shown in FIG. 6 may be used. That is, in FIG. 5 showing the second embodiment of the present invention, the throttle valve 29 has a drinking capacity of 31. Beverage outlet 32. Pressure port 3
3, a diaphragm 35 provided within the main body 34, a valve 36, and a spring 37,
The valve 36 can move up and down by receiving the gas pressure supplied to the pressurizing port 33 with the diaphragm 35. Therefore, if the beverage outlet 31 is connected to the cooling pipe 16, the beverage outlet 32 is connected to the pouring cock 4, and the pressurizing port 33 is connected to the second gas conduit 21, the temperature of the beer in the draft beer barrel 6 can be adjusted as in the previous embodiment. Since the opening degree of the valve 36, that is, the amount of restriction of the beverage channel 38, changes automatically and continuously in accordance with the carbon dioxide gas pressure supplied to the pressurizing port 33, good pouring is possible.

Further, the throttle valve 30 in FIG. 6 showing the third embodiment of the present invention has a drinking capacity of 39. Beverage outlet 40. A main body 42 having a pressurizing port 41, and a bellows 4 provided within this main body 42.
3, a valve 44, and a spring 45, the bellows 43 receives the gas pressure supplied to the pressurizing port 41, and as the bellows 43 expands and contracts, the valve 44 can move up and down. Therefore, the beverage population 39 is the cooling pipe 1
6, and if the beverage outlet 40 is connected to the pouring cock 4 and the pressurizing port 41 is connected to the second gas conduit 21, the temperature of the beer in the draft beer barrel 6, that is, the supply to the pressurizing port 41, as in the previous embodiment. Valve 4 automatically and continuously depending on the carbon dioxide pressure
4, that is, the amount of constriction of the beverage flow path 46 changes, making it possible to perform good pouring.

In addition, as a throttle valve, a seventh embodiment, which is a fourth embodiment of the present invention, is used.
A throttle valve 47 provided with an adjusting screw 52 as shown in FIGS. and 8 may also be used. This throttle valve 47 has a drinking population of 48

Compared to the throttle valve 17 described above, the adjustment screw 52 and spring 53 are
This allows for fine adjustment, which brings about an advantageous effect when pouring out the draft beer with high carbonation content mentioned above. That is,
If the beverage outlet 48 is connected to the cooling pipe 16, the beverage outlet 49 is connected to the pouring cock 4, and the pressurizing port 50 is connected to the second gas conduit 21, the gas pressure supplied to the pressurizing port 50 is relatively low. If the temperature is high, the condition will be as shown in FIG. 7, and if the temperature is high, the condition will be as shown in FIG. It can be done.

9 to 11 show a fifth embodiment of the present invention, in which one end of a cooling pipe 16 disposed in the cooling water 2 is connected to a drinking port 58 of a throttle valve 57, and the other end is connected to a beer conduit 5. It is connected to a dispensing head 8 attached to the draft beer keg 6 via. Further, in the middle of the gas conduit 59 that connects the carbon dioxide gas cylinder 10 and the dispensing head 8 via the pressure reducing valve 11, which is a pressure adjustment mechanism, there is a pressure sensor that detects the gas pressure in these five gas conduits and converts it into an electrical signal. A converter 60 is provided. Furthermore, the beverage outlet 61 of the throttle valve 57
is connected to the pouring cock 4.

Further, a motor 62, which is an actuating device, is mechanically connected to the throttle valve 57 through a rotating shaft 65, and receives a signal from the pressure transducer 60, so that its rotation is controlled.

The pressure transducer 60 and motor 62 constitute a throttle means. Further, the throttle valve 57 is connected to the beverage inlet 5.
8. It is composed of a main body 63 having a beverage outlet 61 and a valve 64 having a threaded part provided in the main body 63,
The valve 64 is configured to move up and down as the rotation shaft 65 is rotated forward or backward by the motor 62. That is, when the pressure detected by the pressure transducer 60 (the carbon dioxide pressure supplied to the draft beer barrel 6) increases, a signal is sent to the motor 62 to rotate the rotary shaft 65 in the direction of closing the valve 64. Conversely, when the gas pressure becomes low, a signal is sent to the motor 62 to rotate the rotary shaft 65 in the direction to open the valve 65. Therefore, as in the embodiment described above, the opening degree of the valve 64 automatically changes depending on the temperature and type of beer in the draft beer barrel 6, that is, the pressure of carbon dioxide gas supplied to the draft beer barrel 6, so that good pouring is possible. .

Also, the throttle valve 57 used in FIG. Instead of the motor 62, a throttle valve 6 as shown in FIG. 12 showing a sixth embodiment of the present invention is used.

The electromagnet 67, which is activated in response to a signal from 0, is used as a throttle means, and the electromagnet 67 and the valve 71 are connected to move the valve 71 up and down. Therefore, the beverage inlet 68 is connected to the cooling pipe 1.
6, and by connecting the beverage outlet 69 to the pouring cock 4, good pouring becomes possible as in the previous embodiment.

Further, as the actuating device, the aforementioned motor 62 and electromagnet 67 are used.
Although not shown in the drawings, the present invention is not limited to this, and can be implemented with a piston cylinder or the like, and furthermore, the signals sent from the pressure transducer 6° to these actuating devices are not limited to electric signals, but can be implemented with various signals and methods.

Further, in the above embodiment, as shown in FIG.
The flow rate of beer has been adjusted by detecting the pressure supplied to the beer with a pressure transducer 6o and automatically controlling the actuating device.
As shown in FIGS. 13 and 16, which are a seventh embodiment of the present invention, the actuating device may be operated manually. That is, the system is the same as that shown in FIG. 9 except that the pressure transducer 60 in FIG. 9 is removed and the motor 62, which is an actuating device, is operated by the operating section 72.

Next, to explain this operation, normally the pressure reducing valve 11 has a first
A scale is displayed as shown in Figure 5, and the pressure is adjusted by turning the central handle according to the temperature and type of beer in the draft beer barrel 6. By turning the handle 73 of the operating section 72, the motor 62, which is an actuating device, is actuated to vary the amount of throttle of the throttle valve 57. That is, the indicator in FIG. 14 is the scale of the pressure reducing valve 11. It should be noted that the actuating device is not limited to the motor 62, but may also be implemented using the electromagnet 67 as in the above-described embodiment or other devices.

Further, in the above embodiment, the pressure reducing valve 11 is used as a pressure regulating mechanism.
Although the explanation has been made using
By using the a-valve 75, optimum dispensing can be achieved almost automatically. FIGS. 17 and 18 show such a pressure control valve 7.

In FIG. 7, a pressure control valve 75 is provided in place of the pressure reducing valve 11 in FIG.
It is the same as that shown in FIG. 1 except that it is closely attached to the lower surface of the draft beer barrel 6. Therefore, even if the temperature of the beer in the draft beer barrel 6 changes, the pressure of carbon dioxide gas supplied from the carbon dioxide gas cylinder 10 to the draft beer barrel 6 automatically changes in response to the change. By setting the settings to be optimal depending on the type of beer (for example, whether it is high carbonated draft beer or not), you can provide beer with stable temperature, flow rate, and foam without the need for specialized techniques. become able to.

Further, although FIG. 17 shows an example in which the heat-sensitive portion 74 is closely attached to the lower surface of the draft beer barrel 6, the heat-sensitive portion 74 is attached to the draft beer barrel 6 as shown in FIG. 19, which is a ninth embodiment of the present invention. The rod holder 76 may be provided with a spring or the like not shown on the top surface of the bar holder 76 so as to be in close contact with the bottom surface of the draft beer barrel 6.
As shown in FIG. 20, which is an embodiment of the present invention, the heat sensitive section 74 may be exposed to the outside air and the pressure control valve 75 may be controlled by this outside temperature. In Figure 19, draft beer barrel 6 is shown as in Figure 17.
The pressure control valve 75 adjusts the carbon dioxide pressure supplied to the draft beer barrel 6 according to the temperature of the beer inside, and the adjusted pressure operates the throttle valve 17.
In the figure, if the draft beer barrel 6 is placed in the outside air for a certain period of time, the temperature of the beer in the draft beer barrel 6 will rise or fall to near the outside temperature.
and a throttle valve 17.

Further, although the pressure control valve 75 is provided adjacent to the carbon dioxide gas cylinder 10 in FIGS. 17, 19, and 20, the pressure control valve 75 is not limited thereto, and may be incorporated into the apparatus as shown in FIG. 21. FIG. 21 shows an eleventh embodiment of the present invention, in which a constant pressure valve 77 is connected to a carbon dioxide gas cylinder 10, and a gas conduit 1
The carbon dioxide pressure supplied from 9 to the pressure control valve 75 is set to 4 to 5.
It is best to keep it at around kg/c-. , also the second
In FIG. 1, the heat sensitive part 74 is brought into close contact with the pipe line between the beer conduit 5 and the cooling pipe 16, so that the beer in the draft beer barrel 6 flows into the cooling water 2.
The pressure control valve 75 and throttle valve 17 are controlled by detecting the temperature before exchanging heat with the air pressure control valve 75 and the throttle valve 17. In this case, the appearance will be the same as in Figure 1, so it will have a clean shape.

Furthermore, even when the pressure control valve 75 is incorporated into the device as shown in FIG. 21, the heat sensing section 74 can be configured to detect the temperature of the draft beer barrel 6 or the outside air as shown in FIGS. 17, 19, and 20. It is also possible to implement the method as shown in FIG. 22.

FIG. 22 shows a twelfth embodiment of the present invention, in which the carbon dioxide pressure supplied from the carbon dioxide cylinder 10 via a constant pressure valve 77 is applied to a heat-sensitive part 74 in close contact with the bottom surface of the draft beer barrel 6 in a rod holder 76. The controlled pressure control valve 75 sends the adjusted carbon dioxide pressure to the draft beer barrel 6 and the throttle valve 17 to control the flow rate.

By the way, although the throttle valve 17 has been explained in FIGS. 17 to 22, the throttle valves 29 and 3 as explained in FIGS. 5 to 8 are not limited to this.
It is clear that 0.47 or other throttle valves could also be used.

23 and 24 show a thirteenth embodiment of the present invention. In FIG. 23, a pressure control valve 75 is provided in place of the pressure reducing valve 11 in FIG. The 9th one is closely attached to the bottom side of the draft beer barrel 6.
It is similar to the figure. In this case as well, as in the embodiment shown in FIGS. 17 and 18, the draft beer barrel 6
Since the pressure supplied to the bottle and the throttle of the throttle valve 57 are automatically adjusted, good pouring is possible. It is clear that the actuating devices, the motor 62 and the throttle valve 57, are not limited to this and can be implemented in various ways.

Furthermore, the heat sensitive section 74 and the pressure control valve 75 can also be changed as shown in FIGS. 19 to 22.

Furthermore, the present invention may be configured as shown in FIGS. 25 and 26. FIG. 25 shows a fourteenth embodiment of the present invention, in which the pressure control valve 7 is replaced with the pressure reducing valve 11 in FIG.
5, a heat sensitive part 74 for controlling this pressure control valve 75 is closely attached to the lower surface of the draft beer barrel 6, and a pressure transducer 60 is further provided in the middle of supplying carbon dioxide gas from the pressure control valve 75 to the draft beer barrel 6. , and is the same as FIG. 13 except that a display device 78 is provided to display the pressure detected by the pressure transducer 60. In this case, the operation of the operation section 72 is performed on the display device 7.

Similar to the embodiment shown in FIGS. 17 and 18, the pressure supplied to the draft beer barrel 6 is automatically adjusted depending on the temperature of the object to be detected, so the pressure is reduced by manually operating the actuator by looking at the display device 78. Controlling the valve 57 allows for good dispensing. Incidentally, the motor 62 and the throttle valve 57, which are actuating devices, can of course be implemented using other methods, and the heat sensing section 74 and pressure control valve 75 can also be changed as shown in FIGS. 19 to 22. be.

Further, in the above embodiment, the throttle valve is provided between the cooling pipe 16 and the pouring cock 4, but the throttle valve is not limited to this. It's okay. Furthermore, although the above embodiment has been explained using a water storage type beverage dispensing device, it can also be implemented with a refrigerator-type beverage dispensing device that stores and cools the draft beer barrel 6 in the refrigerator. It goes without saying that the present invention can be modified in various ways without changing the spirit thereof, such as not only draft beer but also juice, wine, etc.

[Effects of the Invention] As explained above, the present invention operates the throttle valve according to the gas pressure acting on the beverage in the liquid storage pressure container to stabilize the temperature and flow rate of the beverage to be dispensed. Since it is a device, it is effective in that it is possible to perform good pouring regardless of the temperature or type of beverage in the liquid storage pressure container.
