Description

  The present invention relates to a cooling device for a beer barrel that is wound around the body of a beer barrel and keeps the temperature of the beer in the barrel below a certain level.

  A beer server system used in a restaurant or the like is configured to send beer in a beer barrel to a dispenser by a gas pressure from a gas cylinder and to cool to a drinking temperature by a cooling function of the dispenser.

  In this system, it is important to control the temperature of the beer barrel during installation and storage. For example, if a beer barrel is installed in a place with a high room temperature, such as a kitchen in summer, the beer in the barrel becomes too hot, and the dispenser cannot keep up with cooling, so that a fresh beer is provided. In particular, if the temperature of beer exceeds 30 degrees, it will foam abnormally and impair the quality of beer.

  Thus, conventionally, a cover provided with a cold insulation agent on a cover wound around a barrel has been proposed (Patent Document 1).

JP 2002-249173 A

  The thing of patent document 1 can cool a beer barrel only while the cold-retaining agent is cold, and the said cold-retaining function falls with time. In particular, the higher the temperature of the beer barrel, the shorter the cold storage function is lost. That is, there is a problem that it cannot be stably kept cold for a long time.

  Moreover, in order to obtain the cold-retaining function of the cold-retaining agent, it is necessary to put the cover in a refrigerator or a freezer for several hours before use. In other words, there is a problem that the storage space of the refrigerator or the freezer is pressed during that time.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a cooling device that can stably cool a beer barrel for a long time and can secure a reasonable cooling heat source. That is.

  In order to achieve the above-described object, in the present invention, a cover body to be attached to a beer barrel, one end is a water outlet, the other end is a drain outlet, both ends are connected to a cold water source, and the cover body is attached to the mounting surface. The means of providing the cold water circulation path which forms the heat exchange part with the said beer barrel, and the pump which supplies cold water from the said cold water source with respect to this cold water circulation path was used.

  According to this means, by attaching the cover body to the beer barrel and operating the pump, cold water is circulated and supplied from the cold water source to the cold water circulation path, and the beer barrel is removed by the cold water flowing through the heat exchange section of the cold water circulation path. Cooling. This cooling function continues while the pump is running. That is, the cooling effect (cold insulation effect) can be enhanced by continuing to operate the pump during business. However, even when the operation of repeating the operation and stoppage of the pump by a timer or the like is taken, an excessive temperature rise of the beer barrel (beer in the barrel) can be suppressed.

  The essence of the present invention is to suppress an increase in the temperature of beer in the barrel by cooling the beer barrel. In this regard, if attention is paid to which part of the beer barrel can be cooled to effectively suppress the temperature rise of the beer in the barrel, the position of the heat exchange part of the cold water circulation path, that is, the cover body, It is preferable to adopt a configuration that is detachably attached to the waist. This is because even if the upper surface (top surface) of the beer barrel is cooled, there is no beer there, and cooling the waistline can effectively suppress the temperature rise of the beer in the barrel. At the same time, it is also effective to cool the bottom of the beer barrel at the same time.

  Moreover, regarding the raw material of a cover body, it is preferable to have the softness | flexibility wound around the trunk | drum of beer barrels, such as a textile and a resin-made sheet | seat. This is because the cover body can be mounted in close contact with the beer barrel, and thereby the heat exchange part of the cold water circulation path can be brought close to the beer barrel to enhance the cold insulation effect. Moreover, if it is a flexible cover body, handling and removal | desorption to a beer barrel are easy, and also it can fold compactly at the time of storage. However, it does not exclude that the cover body is made of hard plastic or metal.

  On the other hand, the cold water circulation path is preferably formed by meandering the heat exchange part. This is because the cooling function can be further enhanced by increasing the flow path length (heat exchange area) of the heat exchange section.

  Furthermore, the cold water source may be any one that generates and stores cold water, but if a water-cooled beer dispenser is used, it is not necessary to prepare a separate cold water source, which is reasonable.

  ADVANTAGE OF THE INVENTION According to this invention, the temperature of a beer keg (beer in a keg) can be suppressed to 30 degrees or less stably for a long time, and a quality beer can be provided during business. In addition, if the beer in the barrel is cooled to some extent, the capacity burden of the beer dispenser that finally cools the beer to the time of drinking becomes light. Accordingly, if it is assumed that the beer barrel is cooled according to the present invention, it is possible to employ a beer dispenser that is relatively small and inexpensive and has a small cooling capacity. As a result, the installation space for the beer dispenser can be reduced, and running costs such as electricity costs can be reduced.

The whole schematic diagram of the cooling device of the beer barrel which showed one embodiment of the present invention Same explanatory diagram showing usage example

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an entire cooling device for a beer barrel according to an embodiment of the present invention, in which 1 is a cover body, 2 is a cold water circulation path, and 3 is a pump.

  The cover body 1 has a size corresponding to the beer barrel to be mounted, and here has a rectangular shape having a length and a height that can be wound around the beer barrel. The cover body 1 is made of a flexible material such as a textile or resin sheet. And the stop part 1a, such as a hook_and_loop | surface fastener, a hook, and a buckle which hold | maintains the winding state with respect to a beer barrel, is provided in the appropriate location (typically both edges of a short side) of the cover body 1, and the cover body 1 is attached. The beer barrel is detachably mounted.

  On the other hand, the cold water circulation path 2 is constituted by a water pipe such as a hose or a tube, and a part (intermediate part) thereof is integrally disposed on the cover body 1 to constitute a heat exchange part 2a. In this embodiment, the heat exchanging portion 2a is a meandering pipe, and the heat exchange efficiency (cooling efficiency) is increased by ensuring a large flow path length (heat exchange area). Both ends of the circulation path 2 protrude outward from the cover body 1 by a certain length, and one end is used as a water outlet 1b and the other end is used as a drain outlet 1c.

  Here, regarding the relationship between the cover body 1 and the heat exchange part 2a of the circulation path 2, the cover body 1 may have a double structure, and the heat exchange part 2a may be sandwiched integrally therebetween, or the cover body The heat exchanging portion 2a may be integrally disposed on one side (a mounting surface that comes into contact with the beer barrel during winding). Moreover, a pipe line may be formed in the cover body 1 itself, and this may be used as the heat exchange part 2a.

  The pump 3 is provided near the end of the cold water circulation path 2. Then, both ends of the cold water circulation path 2 are connected to an appropriate cold water source, and the pump 3 is operated to take in cold water from the cold water source from the water intake 1b of the cold water circulation path 2, and through the heat exchanging portion 2a, the drain outlet The cold water is circulated so that the water is returned from 1c to the cold water source.

  FIG. 2 shows an example of use of the cooling device. In this example, a water-cooled beer dispenser 4 is employed as a cold water source. In this water-cooled beer dispenser 4, the inside of the housing 1a is filled with cold water, and a beer liquid pipe (not shown) supplied from the beer barrel 5 via a dispenser head (not shown) is cooled with cold water. The beer flowing through the liquid pipe is cooled to the time of drinking, and the cooled beer is poured out from the cock 4b.

  The cooling device connects the both ends 2b and 2c of the cold water circulation path 2 to such a beer dispenser 4 so as to form a circulation path with the internal cold water of the housing 1a. And the cover body 1 is wound around the trunk | drum outer periphery of the beer barrel 5, and the cold water of the beer dispenser 4 is circulated through the cold water circulation path 2 of this apparatus by operating the pump 3. By such an operation, the cold water of the beer dispenser 4 is taken in from the water intake port 2b of the cold water circulation path 2, and the beer barrel 5 is cooled by the heat exchanging portion 2a formed in the cover body 1, so that the beer in the barrel is 30. It can suppress becoming more than degree. Thereafter, the cold water is returned to the beer dispenser 4 from the drain port 2 c of the cold water circulation path 2, and is again made low temperature cold water by the cooling function of the beer dispenser 4. Thereafter, this operation is repeated while the pump 3 is operating, and the beer barrel 5 can be cooled stably for a long time.

  In addition, since this apparatus suppresses finally that the beer in the barrel of the beer barrel 5 becomes 30 degrees or more, the pump 3 may be operated in this range. That is, it is not necessary to continuously operate, and the cooling load of the beer dispenser 4 can be reduced by performing intermittent operation.

  However, by cooling the beer barrel 5 more actively, the temperature of the beer in the barrel can be lowered before being sent to the beer dispenser 4, so even a small beer dispenser with a small cooling capacity is sufficient. Can serve cold beer until drinking.

  Further, by using the water-cooled beer dispenser 4 as a cold water source, it is possible to rationally secure the cold water source using the existing beer server system, but the configuration of the cold water source is not limited to this, and the beer A cold water tank or the like may be prepared separately from the server system.
