Description

  The present invention relates to a beverage cooling supply device and a beverage cooling method for cooling and supplying beer and other beverages, and in particular, a cooling coil separation type in which a cooling coil constituting a beverage cooling unit of a beverage cooling device can be separated and taken out. The present invention relates to a beverage cooling supply apparatus and a beverage cooling method using the same.

  When selling beverages such as beer, sparkling liquor, soft drinks and juices at restaurants, beverage cooling to cool the beverage contained in the storage tank to a suitable temperature and pour it into beverage containers such as cups and glasses A supply device (hereinafter simply referred to as “beverage server”) is used. The beverage server cools the beverage taken out from the storage tank in the process of passing through a cooling coil disposed in the cooling tank, and is poured into the beverage container from the dispensing tap.

  In order to sufficiently exhibit the cooling effect, this beverage server is structured to be immersed in the cooling water in the cooling tank immediately before the pouring tap, that is, to the connection portion between the cooling coil and the pouring tap. By adopting such a structure, the liquid temperature of the beverage in the cooling coil does not rise even when the use interval of the beverage server is long. However, it is necessary to periodically clean the cooling coil and the pouring tap, which are the flow paths of the beverage, for maintenance purposes, and it is necessary to remove the pouring tap from the server body and clean it. In this case, if the pouring tap is removed from the main body, the cooling water will flow out from the opening. Therefore, a plug means for preventing flow is provided, or the cooling water is reduced in advance so that the water level is lowered from the opening. .

  On the other hand, as another method, the above-mentioned problem can be solved by providing the pouring tap body at a position higher than the cooling water surface, but the connecting portion between the pouring tap and the cooling coil cannot be cooled by the cooling water. . In particular, in order to greatly reduce the maintenance work of stores that use the server in recent years, the cooling coil and the dispensing tap of the beverage server have been separated from the device so that they can be removed and cleaned at the management company's washing plant. A cooling coil separation type server has been proposed.

  The cooling coil separation type beverage server will be described with reference to FIGS. That is, FIG. 1 shows a schematic structure inside the beverage server 1 as a whole. The beverage server 1 includes a housing 2, a water tank 3 disposed in the housing 2, and a cooling coil assembly 10 disposed in the water tank 3. The water tank 3 is provided with a cooling coil 4 for cooling the cooling water 5 in the water tank, and a coolant having a lower temperature is supplied from a cooling device (not shown) to cool the cooling water. The cooling coil assembly 10 includes a coil 11 having one end connected to a beverage supply source such as a beer barrel (not shown) and the other end connected to a dispensing tap 12.

  FIG. 2 shows the cooling coil assembly 10 of the beverage server, where (a) shows a front view and (b) shows a side view. FIG. 3 is a perspective view of the cooling coil assembly. The cooling coil assembly 10 shown in the figure has two coiled beverage passages 11 (11a, 11b) wound spirally. A pouring tap 12 (12a, 12b) is attached to one end of each cooling passage 11a, 11b, and pipe joints 13a, 13b connected to a beverage storage container such as a beer barrel are attached to the other end. Is provided. The dispensing tap 12 is detachably attached to the front panel 14 a of the support plate 14 that supports the entire cooling coil 11 and constitutes the cooling coil assembly 10 as a whole. As described above, the cooling coil assembly 10 is disposed in the water tank 3 to which cold water for cooling the beverage is supplied and circulates, and functions as a cooling unit for the beverage server.

  Since the cooling coil separation type beverage server as described above has a configuration in which the cooling coil assembly 10 can be removed, the front panel 14a to which the dispensing tap 12 is attached must be disposed on the top of the housing 2. . For this reason, the pouring tap 12 is located in the upper part of the water tank, and the part to which the pouring tap 12 of the cooling coil 11 is connected (the part indicated by (A) in FIG. 1) is located above the water surface H of the water tank 3. It becomes an exposed part that cannot be immersed in cooling water. Therefore, if the beverage is repeatedly dispensed within a short period of time, the time for the beverage to stagnate in the exposed part is short, and this will not be a problem. If the part stays for a long time, the upper part of the water tank has a normal temperature atmosphere or a high temperature atmosphere due to heat generated by a stirrer or the like of the cooling water, so that the temperature of the cooled beverage rises. If it is poured into a cup or mug in this state, the liquid temperature rises, or in the case of effervescent beverages, the beverage with a high liquid temperature is excessively foamed due to the initial extraction. I get out of order.

  The present invention has been made to solve the above-described problems, and in the beverage server having a structure in which the vicinity of the connection portion with the dispensing tap of the beverage cooling coil is exposed to the atmosphere on the water surface of the cooling water tank, the exposed portion is provided. It is an object to prevent an increase in the temperature of a beverage that stays in the bottle.

  The above-described problems are solved by the following means according to the present invention.

The present invention includes a water tank that contains cooling water, a cooling coil that is disposed in the water tank and that cools the beverage by allowing it to pass through, and a dispensing tap that is connected to the end of the cooling coil and that dispenses the beverage. In the beverage cooling and supply device, the mounting position of the dispensing tap to the water tank is higher than the cooling water surface in the water tank.
Beverage cooling, characterized in that a thin fabric having water permeability is wound around a portion of the cooling coil that is exposed to the vicinity of the connection portion of the dispensing tap, and one end of the fabric is immersed in the cooling water. It is a supply device.

The present invention also includes a water tank that contains cooling water, a cooling coil that is disposed in the water tank and that cools the beverage by allowing it to pass through, and a dispensing tap that is connected to the end of the cooling coil to dispense the beverage. A beverage cooling method using a beverage cooling and supply device in which the position of the dispensing tap attached to the water tank is higher than the cooling water surface in the water tank,
A thin woven fabric having water permeability is wound around a portion of the cooling coil exposed to the vicinity of the connection portion of the dispensing tap, and one end of the woven fabric is immersed in the cooling water to immerse the cooling coil in the atmosphere. A beverage cooling method using a beverage cooling and supplying apparatus characterized in that an exposed portion is cooled.

  In addition, this invention can be implemented more effectively by using a gauze as said textile fabric.

  According to the present invention, the air-exposed portion of the beverage cooling coil can be constantly moisturized and the coil-exposed portion can be always kept at a low temperature by the heat of evaporation of the water. Can be issued.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 4 is a diagram for explaining the beverage server 20 according to the embodiment of the present invention, and shows a schematic configuration diagram when the present invention is applied to the separation-type beverage server 1 described with reference to FIGS. 1 to 3. Therefore, the same components as those of the beverage server 1 described in FIGS. 1 to 3 are denoted by the same reference numerals for convenience of description.

  The beverage server 20 includes a housing 2, a cooling water tank 3, and a cooling coil assembly 10 that can be taken out and separated. The cooling coil assembly 10 has a coiled beverage passage 11 wound in a spiral shape. A pouring tap 12 is attached to one end of the cooling passage 11 and the other end is a beer barrel or the like. Connected to beverage storage container. The dispensing tap 12 is detachably attached to the front panel 14 a of the support plate 14 that supports the entire cooling coil 11 and constitutes the cooling coil assembly 10 as a whole.

  As already explained in the beverage server 1 of FIGS. 1 to 3, the cooling server 20 is exposed to the atmosphere above the water surface H of the aquarium at the connection part (a) with the pouring tap of the cooling coil 11. Yes. In the present embodiment, a belt-like gauze 15 is wound around the exposed portion (A), and the end of the gauze is immersed in the cooling water 5 of the water tank 3. As a form of immersing the end portion in the cooling water 5, the end portion may be immersed in the cooling water while being wound around the coil, or the end portion 15 a may be suspended in the cooling water 5 as illustrated. Good.

  By winding the gauze 15 around the exposed portion and immersing a part thereof in the cooling water, the gauze 15 sucks up the cooling water, and the exposed portion of the coil 11 is always kept wet. The gauze that retains water evaporates according to the ambient temperature, but the exposed portion (a) of the coil is always kept at a low temperature by the heat of evaporation. Therefore, even if the beverage stagnates inside the portion (A) exposed to the air of the cooling coil 11, the beverage is not warmed and can be maintained at a low temperature. Therefore, even when there is an interval between the beverages, the beverage can be poured out in a well-cooled state. And even if a drink is effervescent, it is prevented from foaming too much and it becomes possible to pour a drink in a good state.

  In the above example, the material wound around the exposed portion of the cooling coil is gauze. However, the material is not limited to gauze, and may be any material that has water absorption (water permeability) and moisture retention and can be wound around the coil. Natural vegetable fiber fabrics are preferred. In addition, a film-like sponge is effective because it has a good water absorption and has a structure in which the absorbed water easily evaporates. The reason why gauze is most suitable is a natural plant fiber fabric made of cotton, and is a thin plain fabric woven coarsely, so it is thin and soft, excellent in water absorption and water retention, and also absorbs moisture due to its thinness. Since the moisture easily evaporates and the heat of evaporation is suitably removed, the coil is effectively cooled.

  Next, an embodiment in which the present invention is applied to a cooling coil separation type beer server will be described.

1 has the same structure as the beverage server 1 shown in FIG. 1, the gauze is wrapped twice around the exposed portion of the server for beer whose exposed portion of the cooling coil is about 10 cm, and about 2 cm of one end is suspended in the cold water of the aquarium, The surface temperature of the cooling pipe was measured with the pouring stopped for 30 minutes, and compared with the case where the cold insulation material (foamed urethane) was applied to the exposed part of the cooling coil and the exposed state (no treatment). . In addition, in order to check the foaming state, after pouring for 30 minutes, it was poured into a jockey, the foam thickness of the first cup was applied to the exposed part, the gauze was applied to the exposed part, the cold exposed material was applied to the exposed state (nothing Treatment) was measured and compared. The temperature at the measurement location was 30 ° C.
(1) Surface temperature 30 minutes after stopping pouring When gauze is applied: Approximately 22 ° C
When cold insulation is applied: approx. 23 ° C
Control (no treatment): about 29 ° C
(2) Foam thickness When gauze is applied: approx. 12 mm
When cold insulation is applied: approx. 16mm
Control (no treatment): about 28mm
As can be seen from the above results, it can be seen that the effect of cold insulation is greatest when gauze is wound.

It is a figure which shows the internal structure of the drink server of a cooling coil separation type. The cooling coil assembly is shown, (a) is a front view and (b) is a side view. It is a perspective view of a cooling coil assembly. It is a figure explaining embodiment of this invention.
