Embodiments of the present invention will now be described with reference to the drawings. 1 is a side view of the double pipe 12 of the beverage supply device 1 of the present invention, FIG. 2 is a perspective view of the beverage supply device 1, and FIG. 3 is a diagram showing an internal configuration of the beverage supply device 1. In addition, in FIG.
Those having the same reference numerals as are the same. In the case 5 of the beverage supply device 1 of the present invention, a regenerator tank 7 filled with a gel regenerator 6 and a cooling device 8 including a compressor and a condenser (not shown) are provided. The beverage cooling pipe 9 drawn out from the beverage tank 2 is inserted and fitted into an outer pipe 11 having a larger pipe diameter, and a double pipe 12 is constituted by both. A gap 13 is formed between the beverage cooling pipe 9 and the outer pipe 11, and an outlet pipe 14 is provided at the end of the outer pipe 11 located on the upstream side and the downstream side of the flow of the beverage in the beverage cooling pipe 9. , And the inlet pipe 15 are respectively connected,
The space 13 communicates with the space 13.

The double pipe 12 is wound in a coil shape and immersed in the regenerator 6 in the regenerator tank 7, and the outlet pipe of the condenser drawn from the cooling device 8 has an expansion valve 16 installed therein. Is connected to the inlet pipe 15 and the outlet pipe 14 is connected to the suction side of the compressor of the cooling device 8. Further, the temperature sensing cylinder 17 of the expansion valve 16 is provided so as to sense the temperature of the outlet pipe 14, and thus the interval 13 serves as an evaporator of the cooling device 8. The beverage cooling pipe 9 coming out of the outer pipe 11 is connected to the cock 4 provided on the upper front surface of the case 5.

When the cooling device 8 is operated with the above configuration,
The high-temperature and high-pressure refrigerant discharged from the compressor is condensed in the condenser, decompressed by the expansion valve 16, and then flows from the inlet pipe 15 into the space 13 in the double pipe 12. The depressurized refrigerant evaporates in the space 13, cools the inner beverage cooling pipe 9 by the endothermic action generated at that time, and at the same time cools the outer cool storage agent 6, so that the beverage cooling pipe 9 and the cool storage agent 6 become low in temperature. The degree of superheat of the refrigerant in the space 13 is adjusted by the expansion valve 16.

When the cock 4 is opened in such a state, the beer in the beverage tank 2 is extruded into the beverage cooling pipe 9 by the pressure from the carbon dioxide gas cylinder 3 and passes through the beverage cooling pipe 9 in the double pipe 12 portion. It comes out from the outer pipe 11 and is extracted from the cock 4. At this time, the flow of the beverage becomes a counterflow with the flow of the refrigerant in the interval 13 and is cooled by the refrigerant that evaporates in the interval 13 via the wall surface of the beverage cooling pipe 9, so that the beverage is instantly drinkable at a low temperature. It will be leaked from the cock 4.

Here, when the beverage is continuously extracted, the refrigerant is heated through the beverage cooling pipe 9 and the temperature tends to rise. However, since the cold storage agent 6 is at a low temperature, the refrigerant is passed through the outer pipe 12. Since the refrigerant is cooled as a result, the temperature rise is suppressed. Therefore, even if the beverage is continuously extracted, the reduction of the cooling effect is suppressed, and the beverage just before drinking can be continuously extracted. Further, at this time, since the water tank as in the conventional case is not required, the maintenance and inspection work can be extremely simplified, and the entire apparatus can be downsized.

Although the present invention is applied to the beverage supply device for extracting beer in the embodiments, the present invention is not limited to this, and the present invention is effective for a beverage supply device for extracting various beverages such as juice.

[0016]

As described above in detail, according to the invention of claim 1, the beverage cooling pipe is constantly cooled by the low temperature refrigerant supplied in the space between the beverage cooling pipe and the outer pipe, so that the beverage extruded from the beverage tank. In the process of passing through the beverage cooling pipe, it will be instantly cooled from the wall surface that is at a low temperature, so that the ready-to-drink beverage can be smoothly supplied. In particular, unlike the conventional case, a water tank for cooling the beverage cooling pipe is not required, so that the maintenance and inspection can be remarkably simplified and the size of the entire device can be reduced.

Further, according to the second aspect of the invention, since the double pipe constituted by the beverage cooling pipe and the outer pipe is immersed in the cool storage agent, the cool storage agent is supplied at a low temperature within the space inside the outer pipe. It is always cooled by the refrigerant to a low temperature, and even if the beverage is continuously extracted, the temperature rise of the low-temperature refrigerant in the interval is suppressed by cooling from the regenerator, so drinks that are ready for drinking at a low temperature can be continuously It will be able to be extracted.
