Abstract

PROBLEM TO BE SOLVED: To cool a beverage at an approximately uniform beverage temperature even when the discharging speed of the beverage is high, and also, eliminate fear for the freezing in a beverage transfer pipe, and in addition, miniaturize the whole of a server, and reduce the winding number of the beverage transfer pipe as well by making the spiral diameter larger. SOLUTION: The transfer pipe 16 for the beverage, e.g. a draft beer, is spirally arranged in a server main body 11 of a heat-insulating structure, which is formed into a box shape. Water 18 in the server main body 11 is led to a cooling unit 19 by a water-circulating pump 20, and the water 18 is cooled. Then, the supercooled water is jetted downward at the upper section of the server main body 11. By bringing the jetted cooling water into contact with a contact member 24, one section of the cooling water is instantly frozen, and sherbet-form ice 34 is made, and stored. Then, the draft beer which is fed to the transfer pipe 16 from the outside is cooled by the water 18 containing the sherbet-form ice 34, and the draft beer is discharged from a discharging cock 17.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage server used to cool and dispense drinks such as draft beer sent from a beverage supply source such as draft beer barrels.

[0002]

2. Description of the Related Art Conventionally, draft beer servers have been used for cooling and discharging draft beer sent from draft beer barrels, for example. As a conventional draft beer server, a brine pipe and a draft beer transfer pipe are spirally arranged in the vertical direction on the outer peripheral portion and the inner peripheral portion in the server body of the heat insulation structure,
A stirrer is provided at the center of the spiral of the draft beer transfer pipe, and this stirrer is driven by a stirrer motor arranged outside the server main body. The brine is cooled by a cooling device and circulated through the brine pipe. The water is cooled to make ice around the brine pipe, and the draft beer sent from the draft beer barrel to the draft beer transfer pipe is cooled using the latent heat of melting of ice serving as the cold storage agent, and the cooled draft beer is transferred to draft beer. 2. Description of the Related Art There is known a configuration in which an outlet cock is connected to an outlet cock.

[0003]

However, in the above-described conventional configuration, if the drafting speed of the draft beer is high, it takes time for the ice to melt, so that the cooling water temperature rises and the draft beer temperature increases. And high value is inferior. Further, if ice is made near the draft beer transfer pipe, draft beer in the draft beer transfer pipe may be frozen, so that the amount of ice making is restricted and the draft beer cooling efficiency is poor. To prevent this, the whole draft beer server needs to be enlarged, which not only requires a large installation space but also becomes expensive. Furthermore, since the draft beer transfer pipe is arranged inside the brine pipe, if it is set to a predetermined length for cooling, the helical diameter becomes smaller and, therefore, it is necessary to increase the number of windings. Costly and expensive.

[0004] An object of the present invention is to solve the above-mentioned conventional problems. By cooling a beverage in a beverage transfer pipe with water containing sherbet-like ice, the dispensing speed of the beverage is reduced. Even at high speed, the beverage temperature can be cooled almost constantly, so that the value of the beverage can be increased, and the danger of freezing in the beverage transfer tube can be eliminated, and therefore, the cooling efficiency of the beverage can be improved. In addition, the size of the entire server can be reduced, so that not only the installation space can be reduced, but also the cost can be reduced, and further, the beverage transfer pipe can be cooled. Therefore, when the length is set to a predetermined length, the spiral diameter can be designed to be large, so that the number of windings can be reduced, and therefore, the processing can be easily performed. It is intended to provide a beverage server to be able to contribute to the reduction of the cost.

[0008] The discharge means may be configured so that the liquid discharged from the server body circulates to the cooling means.

As the cooling means, a cooling device for directly cooling the liquid can be used, or as the cooling means, a cooling device for cooling the brine and heat exchange of the liquid using the brine cooled by the cooling device. And a heat exchanger for cooling.

According to the present invention configured as described above,
By cooling the beverage in the beverage transfer tube with water containing sherbet-like ice, the beverage temperature can be cooled almost constantly even when the beverage is discharged at a high speed, and the possibility of freezing in the beverage transfer tube is reduced. It is possible to reduce the size of the entire server, and further, when the beverage transfer pipe is set to a predetermined length for cooling, the spiral diameter thereof can be designed to be large. The number of turns can be reduced.

The temperature of the supercooled water spouted from the spout 23 is set to about 0 ° C.
By setting the temperature to −3 ° C., the supercooled water can be brought into contact with the contact member 24 to produce sherbet-like ice.

A stirring shaft 25 is vertically disposed at the center of the spiral of the draft beer transfer pipe 16. The stirring shaft 25 is rotatably supported with its upper part inserted through the cover 13. The agitating blade 26 is attached so that it is located at an intermediate portion in the vertical direction of the spiral of the draft beer transfer pipe 16. The upper protruding portion of the stirring shaft 25 is linked to a stirring motor 27 mounted on the cover 13, and

The supercooled water is guided to the cooling unit 19 and cooled to about 0 ° C. to −3 ° C.
1 and is ejected downward from the ejection port 23. The jetted supercooled water comes into contact with the contact member 24, so that a part thereof is instantaneously frozen and becomes sherbet-like ice 34 and falls into the water 18. Thus, ice is stored in the server body 11. At the same time, the stirring shaft 25 and the stirring blade 26 are rotated by the driving of the stirring motor 27 to stir the water 18 and the sherbet-shaped ice 34, thereby cooling the draft beer transfer pipe 16 as a whole.

3. Supply carbon dioxide into the draft beer barrel 1 via the carbon dioxide supply pipe 32 and the inlet 31 of the dispense head 28,
The draft beer in the draft beer barrel 1 is pressurized by carbon dioxide gas and sent to the draft beer transfer pipe 16 of the draft beer server 3 via the outlet 29 and the outlet pipe 30. The draft beer sent into the draft beer transfer pipe 16 is rapidly cooled through the draft beer transfer pipe 16 while being spirally transferred along the draft beer transfer pipe 16, and is supplied to the pouring cock 17. Therefore, draft beer cooled by opening and closing the pouring cock 17 can be poured.

As described above, since the sherbet-like ice 34 is used, it can be melted instantaneously. Therefore, even if the drafting speed of the draft beer is high, the draft beer is transferred by the latent heat of melting generated instantly as described above. Draft beer conveyed in the pipe 16 can be cooled effectively, and the cooling temperature of draft beer can be cooled substantially uniformly.

The draft beer transfer pipe 16 is surrounded by water 18 containing sherbet-like ice 34, and never drops below 0 ° C., so that draft beer in the draft beer transfer pipe 16 does not freeze.
Moreover, since the ice making position is not restricted as in the conventional example, the draft beer server 3 can be downsized as a whole. Further, since a brine pipe is not required unlike the conventional case, when the draft beer transfer pipe 16 is set to a predetermined length for cooling, the spiral diameter thereof can be designed to be large, and the number of windings can be reduced. Can be.
