Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a dispensing device for cooling and dispensing a sparkling beverage.

(Prior Art) A wide variety of beverages are used, including draft beer and various soft drinks, but draft beer, which is a sparkling beverage, will be explained below as an example. As is well known, draft beer contains a certain amount of carbon dioxide gas, and foaming occurs when carbon dioxide gas is liberated, which is not a desirable phenomenon.

When draft beer is in a non-flowing state, the relationship between pressure and temperature is such that when the pressure is kept constant, the higher the temperature, the easier it is to foam, and when the temperature is kept constant, the easier it is to foam when the pressure is lower. The relationship between the two maintains a balanced and stable state under certain conditions, but when it is in a fluid state, the balance between these conditions is broken and carbon dioxide gas foams. The foaming condition in this case is related to the flow rate and the flow state; when the flow rate is high, the foaming is intense and when the flow rate is slow, the foaming is slow.

Conventionally, when pouring draft beer into a cup or the like for sale, the draft beer is cooled to a constant temperature in a storage tank installed in a refrigerator room when it is large-scale, and from this storage tank a pouring device on the sales counter is used. The pipes were connected by long pipes, and the pipes were poured by opening and closing the tap of the pouring device. However, in this case, even if the liquid storage tank is cooled to an appropriate temperature, the temperature may rise before reaching the dispensing device, or the liquid storage tank may not be cooled to the appropriate temperature, so generally speaking, dispensing A relatively long beverage cooling pipe was wound around the inside of the device to provide a cooling function such as cooling draft beer.

(Problem that the invention aims to solve) However, the temperature of the draft beer flowing into such a pouring device varies greatly due to the liquid storage tank connected to it, the length of piping from this to the pouring device, and the heat insulation structure. There were cases where proper dispensing could not be performed because the

The present invention eliminates such drawbacks and aims to provide a cooling dispensing device that always dispenses a beverage at an appropriate temperature regardless of the distance from the beverage supply source to the dispensing device.

[Structure of the idea]

(Means for Solving the Problems) In order to solve the above problems, the present invention stores a cooling liquid in a cooling water tank and includes an evaporation pipe connected to a refrigeration device and a beverage supply pipe connected to a beverage supply source. A device for dispensing a beverage from a pouring pot provided at an end of the beverage cooling pipe, comprising: a pump for taking out the cooling liquid from the cooling water tank; and an object to be cooled provided outside the cooling water tank. a joint provided at the discharge port of the pump; a return conduit that is removably connected to the joint as needed and returns the coolant taken out by the pump directly to the cooling water tank; A cooling pipe is provided in place of the return pipe, if necessary, and is detachably connected to circulate the cooling liquid taken out from the cooling water tank to cool the object to be cooled. That is.

(Function) By selectively using the return pipe and the cooling pipe as necessary, it is possible to prevent the temperature of the beverage from changing depending on the distance from the beverage supply source to the pouring device.

(Embodiment) The present invention will be described below with reference to an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a cooling water tank, and the outside of the cooling water tank 1 is covered with a heat insulating material 2, and a cooling liquid 3 such as water or antifreeze is stored in the cooling water tank 1. An evaporation pipe 5 connected to a refrigeration device for cooling the cooling liquid 3 and a beverage cooling pipe 6 for cooling the beverage are immersed in the cooling liquid 3. Both ends of the beverage cooling pipe 6 are led out to the outside of the cooling water tank 1, and one end of the pipe is connected to an inlet 7 and connected to a beer barrel or liquid storage as a beverage supply source via a pipe 8 as an object to be cooled. Tank (hereinafter referred to as liquid storage tank)
9, the other end of the pipe is connected from the outlet 10 to a pouring pot 11, and the pouring pot 11 is opened to pour draft beer into a cup (not shown). The draft beer as a beverage in the liquid storage tank 9 is in contact with carbon dioxide gas which has been adjusted to an appropriate pressure by a pressure regulator 13 from a carbon dioxide gas cylinder 12, and the draft beer is sent out from the liquid storage tank 9 due to the pressure of this carbon dioxide gas. .

The cooling liquid 3 is cooled in the evaporation pipe 5 by the operation of the refrigeration device 4, while the draft beer is cooled by the cooling liquid 3 while flowing in the beverage cooling pipe 6. When an illegal liquid is used as the coolant 3, the liquid temperature control element 14 detects the temperature of the coolant 3 and controls the operation of the refrigeration device 4 in order to prevent overcooling of the draft beer. When water is used as the coolant 3, ice 15 is generated around the evaporation tube 5, and the coolant 3 is cooled by the melting heat of the ice 15. In this case, the liquid temperature control element 14 controls the ice storage control element. Will be using it.

By the way, if the distance between the liquid storage tank 9 and the cooling water tank 1 is close enough that temperature rise while flowing in the piping 8 is not a problem, connect the joint 22 of the discharge port 17 of the pump 16 as shown in FIG. One end of a pipe 18 serving as a return pipe is removably connected to the pipe, and the other end is connected to an outlet 19, and the coolant 3 taken out from the cooling water tank 1 is directly returned to the water tank 1 via the pipe 18 for circulation. This improves heat exchange with the evaporation pipe 5 and the beverage cooling pipe 6.

In addition, if the distance between the liquid storage tank 9 and the cooling water tank 1 is large and the temperature rise while flowing in the pipe 8 becomes a problem, remove the pipe 18 from the joint 22 of the discharge port 17 and the outflow port 19, As shown in Figure 2,
Circulation hose 20 as a cooling pipe that covers the pipe 8
One end is detachably connected to the joint 22 of the discharge port 17, and the other end is connected to the outflow port 19 via the return hose 21. As a result, pump 1
The cooling liquid 3 discharged from the cooling water tank 1 cools the pipe 8 and then flows into the cooling water tank 1 to cool the cooling liquid 3 in the cooling water tank 1.
will be circulated.

The present invention is characterized in that the method shown in FIG. 1 and the method shown in FIG. 2 described above can be used appropriately as required. In other words, the draft beer is in the pipe 8.
If the temperature rise becomes a problem during the flow, remove the piping 18 shown in FIG. 1 and connect one end of the circulation hose 20 shown in FIG. 21 to the outlet 19.

In addition, in the above embodiment, an example was shown in which the liquid storage tank 9 was left in an atmosphere at outside temperature, but the present invention is not limited to this. The piping 8 may be connected to the inlet 7 of the pouring device on the sales counter outside the refrigeration room, and at this time the cooling liquid 3 in the cooling water tank 1 may be circulated through the piping 8 by the pump 16. It goes without saying that it is also possible to circulate and cool the cooling liquid 3 through an object completely separate from the piping 8, such as the liquid storage tank 9. Furthermore, the piping 8 and the circulation hose 20 may be arranged so that they are in contact with each other,
Further, it is more preferable that the piping 8, the circulation hose 20, and the return hose 21 be provided with a heat insulating material (not shown).

[Effect of idea]

As explained above, according to the present invention, there is a return pipe for directly returning the cooling liquid taken out from the cooling water tank to the cooling water tank, and a cooling liquid taken out from the cooling water tank is circulated outside to cool the object to be cooled. The cooling pipes can be selectively used as needed, and a beverage at an appropriate temperature can be dispensed regardless of the distance from the beverage supply source to the cooling water layer.
