Description

[Detailed description of the invention] The present invention relates to a carbonated beverage dispensing device that produces carbonated water from drinking water and carbon dioxide gas, mixes this carbonated water and beverage syrup, and pours it out from a pouring pulp. , relates to improvements in cooling structures for carbonated water and beverage syrups.

A conventional device of this type is shown in FIG.

A coil-shaped evaporator 14 is provided near the inner wall of the cooling tank 13 filled with cooling water 23, and a carbonator tank 16 is provided inside the evaporator 14.
A water cooling pipe 17 and a syrup cooling pipe 18, each wound into a coil, are provided concentrically and stacked next to each other, and a stirring blade 21 is installed in the center to circulate the cooling water as shown by the arrow. , the drinking water is injected into the carbonator tank 16 cooled by the water cooling pipe 17, and the carbon dioxide gas supplied into the carbonator tank 16 through the gas pipe 12 is evaporated to produce carbonated water 11. The carbonated water 11 is led to the pouring pulp 20 through the carbonated water outlet pipe 19, and the beverage syrup cooled through the syrup cooling pipe 18 is guided to the pouring pulp 20, where it is mixed and poured. It had become.

The most important point in this type of carbonated beverage dispensing device is whether or not the carbonation level of the dispensed carbonated beverage can be sufficiently increased.

It is known that the carbonicity of water to be carbonated increases as the water temperature becomes lower, as the carbon dioxide gas pressure increases, and as the water and carbon dioxide gas come into contact more frequently.

However, increasing the carbon dioxide pressure requires the carbonator tank 16 and the pipes 12, 17 connected thereto.
It is necessary to improve the pressure resistance of the carbonator tank 16, and also to increase the water pressure to inject water into the carbonator tank 16, that is, the ability of the water pump (not shown) that supplies drinking water, and the driving power also needs to be increased. It is desirable to keep the pressure as low as possible.

In addition, lower pressure is preferable because there is less pressure change during pouring, so that the release of carbon dioxide from the carbonated beverage can be suppressed to a smaller extent.

Therefore, in order to obtain a carbonated beverage with a higher degree of carbonation, sufficient cooling of the drinking water and appropriate injection speed and flow rate of the drinking water in the carbonator tank are necessary for stirring and mixing in the carbonator tank. At the same time, the carbonated water in the carbonator tank 16 and the carbonated water outlet pipe 19 leading from this to the pouring pulp 20 is sufficiently cooled, and the beverage syrup in the syrup cooling pipe 18 is also sufficiently cooled. It is preferable to keep it.

It goes without saying that this cooling is important not only for increasing carbonation level but also for increasing the refreshing feeling that is a characteristic of carbonated drinks.

In addition, the injection of drinking water into the carbonator tank 16 is temporarily and rapidly performed when the amount of carbonated water 11 held in the carbonator tank 16 becomes less than a certain amount. The temperature of the water is difficult to lower, and it is necessary to cool the water more actively in the carbonator tank 16.

However, as mentioned above, if the carbonator tank 16, water cooling pipe 17, and syrup cooling pipe 18 are arranged side by side,
In a structure in which stirring blades 21 are provided at the center of the cooling pipes 17 and 18 to circulate the cooling water 23, the cooling pipes 17 and 18
Since the cross-sectional area of the circulation flow path in the external measurement is wider than that in the internal measurement, the flow rate of the cooling water 23 flowing around the carbonator tank 16 is slow, and the carbonator tank 16 has a strong swirling flow caused by the stirring blades 21. However, the carbonator tank 16 is not effectively cooled, and the carbonator tank 16 cannot be effectively cooled, and it cannot be said to be sufficient in efficiently dispensing a carbonated beverage with a high refreshing feeling.

In order to solve the above-mentioned drawbacks, the present invention provides a carbonated water cooling pipe in the water cooling pipe, syrup cooling pipe, carbonator tank, and carbonated water outlet pipe leading from the carbonator tank to the poured pulp. It is designed so that this part can also be effectively cooled.1. To provide a carbonated beverage dispensing device capable of dispensing well-cooled carbonated beverages with high acidity with high efficiency.

Hereinafter, a description will be given of FIGS. 2 and 3 showing an embodiment of the present invention.

Note that in FIGS. 2 and 3, the same numbers as those in FIG. 1 are assigned the same names and functions as those in FIG. 1.

An evaporator 14 is installed along the inner wall of the cold water tank 13.
Carbonator tank 16 and water cooling pipe 24. The syrup cooling pipe 18 and the carbonated water cooling pipe 25 are submerged, and as shown in FIG. 3, the water cooling pipe 24. Syrup cooling pipe 18. The carbonated water cooling pipe 25 is formed into a meandering shape so that it has a C-shape in a plan view.

A carbonator tank 16 is assembled into the open end of the C-shape, and the carbonator tank 16 and each of the cooling pipes 24.18.2 are connected to each other.
5 are arranged in a ring shape, and a stirring blade 21 is arranged in the center,
A circulation flow path for the cooling water 23 is formed inside and outside the annular shape.

Note that the evaporator 14 is connected to a refrigerator 22,
In addition to cooling the cooling water 23, the operation of the refrigerator 22 is controlled by an ice detector 26 so that a certain amount of ice 15 is always stored around the evaporator 14.

Further, one end of the water cooling pipe 24 is connected to the carbonator tank 16.
0 top and the other end is the drinking water pipe 10. Check valve9. The water is supplied via a water pump 8 to a drinking water source 30 such as tap water.

The carbonator tank 16f (in which the carbon dioxide gas in the carbon dioxide gas cylinder 1 is reduced to a predetermined pressure by the first pressure regulator 2
as well as being introduced through the gas pipe 12.

Drinking water is pressurized by the water pump 8, cooled to an appropriate temperature while flowing through the water cooling pipe 24, and is injected into the carbonator tank 1 as it comes into contact with the carbon dioxide gas and becomes carbonated water.
6 is stirred by a jet stream to increase carbonation level w.

The carbonated water 11 thus produced is stored in a carbonator tank 16.
The carbonated water cooling pipe 25 opens at the bottom of the carbonated water cooling pipe 25, and the carbonated water control valve 28 leads to the extraction pulp 20.

On the other hand, from carbon dioxide gas cylinder 1 to 1st. The carbon dioxide gas, which has been brought to a predetermined pressure through the second pressure regulators 2 and 3, is introduced into the syrup tank 6 through the second gas pipe 5.
By pressurizing the inside of the syrup tank, the syrup 4 in the syrup tank nose is sent from the syrup outlet pipe 7 to the syrup cooling pipe 18, cooled in the syrup cooling pipe 18, and guided to the pouring pulp 20 via the syrup control valve 27. ing.

Note that a water level detector 29 is installed in the carbonator tank 16.
is installed to control the operation of the water pump 8 so that the level of the carbonated water stored therein is always within a certain range.

By opening the pouring pulp 20, the carbonated water, which has been cooled to an appropriate temperature by the pressure of the carbonator tank 16 and the syrup tank 6, is mixed in the 70-tubular extruded pouring pulp 20 and poured out as a carbonated drink. It is supposed to be done.

The carbonated beverage dispensing device according to the present invention has the water cooling pipe 24, the syrup cooling pipe 18, the carbonated water cooling pipe 25, and the carbonator tank 16 arranged as described above. Since the water 230 comes into contact with a strong swirling flow and the space between them and the ice 15 stored on the inner wall of the cold water tank 13 can be configured to be quite narrow, the swirling flow in this part also becomes high speed, and the above-mentioned parts can be effectively cooled both inside and outside of the annular shape, and at the same time can be downsized to the width of the cold water tank 13.

In this way, not only the water cooling pipe 24 but also the carbonaceous tank 1
6 is cooled more actively, the drinking water in the carbonator tank 16 is well cooled and has a low temperature, which facilitates the dissolution of carbon dioxide gas.

There, the carbonation level of the carbonated water produced in the carbonator tank 16 is further increased.

Further, as described above, since the carbonator tank 16 itself is cooled more actively, the cooling by the water cooling pipe 24 can be made to the level of pre-cooling.

Therefore, the water cooling pipe 24 can be made relatively thick or short to reduce the pipe resistance.

Therefore, drinking water can be injected into the carbonator tank 16 at high speed with a lower pressure water pump 8, and the carbonation degree can be improved by contact with carbon dioxide gas. It is possible to use a pipe with a low temperature, which eases operating conditions, reduces operating power, and reduces pipe line pressure resistance.

Furthermore, since the carbonated water cooling pipe 25 is provided between the carbonator tank 16 and the extracted pulp 20 for cooling, the carbonator tank 16 can be cooled immediately after the water pump 8 is stopped.
Even if the spouting pulp 20 is opened when the carbonated water inside the bottle has not been sufficiently cooled to drinking temperature, the carbonated water will be cooled while flowing through the carbonated water cooling pipe 25, resulting in a carbonated beverage that has been cooled to an appropriate temperature. is poured out.

Furthermore, since the carbonated beverage that is poured out is sufficiently cooled, pressure fluctuations during pouring and carbon dioxide emissions due to flow can be suppressed to a lower level.

As described above, the carbonated beverage dispensing device according to the present invention has a rational and efficient structure, and its advantages can be summarized as follows.

(b) The cooling capacity of drinking water can be relaxed and the spouting speed of drinking water can be increased, and at the same time, the overall cooling capacity can be greatly improved, and therefore a carbonated drink with higher carbonation temperature can be obtained.

The discharge pressure of the water pump can be reduced, and costs can be reduced by reducing the operating power of the water pump and reducing the pressure resistance of the water pump and the piping system.

C. There is little variation in carbonated beverage temperature due to continuous pouring.

2. It can be downsized to a large device.
