[Prior art]
As the frozen beverage dispenser mentioned above, a dispenser for a carbonated frozen beverage (FUB (Frozen Uncarbonated Beverage)) and a dispenser for a carbonated frozen beverage (FCB (Frozen Carbonated Beverage)) are known.
[0003]
Here, the dispenser for non-carbonated frozen beverages is for producing sorbet-like frozen beverages by cooling and stirring syrup and dilution water in a tank open to atmospheric pressure. The volume expansion rate of the finished beverage that has become a sherbet just by entraining some air in the container is low. On the other hand, the dispenser for carbonated frozen beverages is a sorbet-like frozen beverage produced by cooling and stirring in a pressure tank in which syrup and diluted water are pressurized with carbon dioxide gas. Since the bubble of carbon dioxide gas is mixed in the beverage, the volume expansion rate of the finished beverage is high, and the mouthfeel when the beverage is contained in the mouth is softer and cooler than the non-carbonated frozen beverage.
[0004]
Next, the structure of a conventional dispenser and the beverage system of the dispenser are shown in FIGS. 3 and 4 for a dispenser for producing a non-carbonated frozen beverage.

[0006]
With such a configuration, a fixed amount of syrup and dilution water are supplied to and stored in the tank 1 of the dispenser main body A through the syrup supply line 11 and the dilution water supply line 12, and the operation of the cooling unit 4 is performed on the surface of the evaporator 5 a of the cooling cylinder 5. A sorbet-like frozen beverage is produced by stirring the frosted ice and the liquid beverage while scraping the frozen ice with the stirring blades 5b and 5c serving as augers. When the cup is set on the bend stage 3 and the cock of the beverage nozzle 2 is opened, the frozen beverage is discharged and supplied from the tank 1 by the feeding action of the screw type stirring blades 5b and 5c assembled to the cooling cylinder 5.
[0007]
On the other hand, a conventional frozen beverage dispenser for producing a carbonated frozen beverage comprises a tank (corresponding to the tank 1 in FIG. 3) mounted on the dispenser body as a sealed pressure tank, and a carbon dioxide gas cylinder is placed in the pressure tank. The carbon dioxide gas is kept in a pressurized state, and the syrup and dilution water supplied through the syrup supply line and dilution water supply line are cooled and stirred to produce a sherbet-like frozen beverage.
[0008]
[Problems to be solved by the invention]
As for the non-carbonated frozen beverage and the carbonated frozen beverage, the carbonated frozen beverage has a higher volume expansion rate and soft mouthfeel than the non-carbonated frozen beverage. In order to manufacture frozen beverages, it is necessary to equip a pressure tank that requires pressure resistance and airtightness as a tank to be mounted on the dispenser body. Compared to dispensers, the product cost is significantly higher, which is one of the causes that hinders its spread.
[0009]
The present invention has been made in view of the above points, and its purpose is to make it possible to easily produce a carbonated frozen beverage by utilizing a tank open to atmospheric pressure mounted on a dispenser for a conventional non-carbonated frozen beverage. An object of the present invention is to provide a frozen beverage dispenser.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a cooler also serving as an auger type ice maker and a beverage agitator are incorporated, and a beverage supply nozzle is drawn out toward a bend stage. equipped with tanks, syrup supply line, syrup was fed to the tank through a dilution water supply line, the frozen beverage dispenser to produce a frozen beverage by cooling the dilution water, carbonated inwardly atmospheric open type tank of the An air supply nozzle connected to the gas cylinder is incorporated, and carbonic acid gas is blown into the liquid of the beverage stored in the tank through the air supply nozzle to produce a carbonated frozen beverage.
[0014]
With this configuration, the carbon dioxide gas blown into the tank through the air supply nozzle becomes bubbles and mixes with the beverage in the process of diffusing in the tank, and is taken into the sherbet-like beverage. It should be noted that surplus carbon dioxide gas that could not be absorbed by the beverage escapes onto the liquid surface of the beverage and is diffused to the atmosphere side. Thus, without the addition of carbon dioxide gas pressure here instead a tank mounted on the dispenser body to the pressure tank of the closed type, in here by utilizing an atmospheric pressure open type tank simply adding air supply nozzle carbon dioxide A carbonated frozen beverage can be easily produced.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, FIG. 1 the embodiment of the present invention will be described with reference to indicate to the real施例in FIG. In addition, in the figure of each Example, the same code | symbol is attached | subjected to the same member corresponding to FIG. 3, FIG. 4, and the description is abbreviate | omitted.
[0016]
[Example 1]
FIG. 1 shows Example 1 according to the embodiment of the present invention. In this embodiment, the dispenser main body A and the atmospheric pressure open tank 1 mounted on the dispenser main body are the same as those of the conventional structure shown in FIG. On the other hand, with regard to the automatic beverage supply unit B combined with the dispenser main body A, a carbonator 13 is newly connected after the water pump 12b of the dilution water supply line 12 leading to the water tap 10 and is pulled out from the carbonator 13. A carbonated water supply line 14 is piped between a syrup nozzle 6 disposed in a tank 1 of the dispenser main body A (the tank 1 contains an auger type ice making machine 5 similar to that described in FIG. 3). . Further, carbon dioxide is supplied to the carbonator 13 through a carbon dioxide supply line 15 piped between the carbon dioxide cylinder 9. 14a is a carbonated water distributor, 14b is a carbonated water valve, 14c is a carbonated water flow regulator, 14d is a sanitation valve, and 14e is a three-way joint with a check valve.
[0017]
With such a configuration, when the dispenser is operated, carbonated water is produced and stored in the carbonator 13 using the dilution water supplied from the water tap 10 and the carbon dioxide supplied from the carbon dioxide cylinder 9 as raw materials. When a syrup supply command is given as the beverage level of the tank 1 mounted on the dispenser body A decreases, carbonated water is extracted from the carbonator 13 together with the syrup extracted from the syrup container 8, and the carbonated water supply line 14, syrup valve is extracted. The tank 1 is replenished through 11c. As a result, as the frozen beverage is cooled and stirred in the tank 1, the carbon dioxide dissolved in the carbonated water is foamed and the fine bubbles are mixed into the sherbet-like beverage, whereby the volume of the finished beverage is increased. A carbonated frozen beverage having a high expansion rate and a soft mouthfeel is produced. It should be noted that surplus carbon dioxide that cannot be mixed in the beverage escapes from the tank 1 to the atmosphere after it escapes onto the liquid surface.
[0018]
[Example 2]
FIG. 2 shows Example 2 according to the embodiment of the present invention. In this embodiment, a carbon dioxide gas supply nozzle 16 is disposed at the inner bottom of the tank 1 that is open to atmospheric pressure similar to that mounted on the dispenser body of FIG. A gas nozzle 16 is connected to the carbon dioxide gas cylinder 9 through a gas line 15. The air supply nozzle 16 is made of porous ceramics, and the carbon dioxide gas supplied from the carbon dioxide gas cylinder 9 becomes fine bubbles and diffuses into the tank. Note that an air supply control valve 17 is connected to the carbon dioxide supply line 15 and is controlled to open and close by a command from the operation controller so that carbon dioxide is intermittently supplied to the tank 1. In addition, the syrup and dilution water are supplied with respect to the tank 1 through the syrup nozzle 6 similarly to the drink system | strain described in FIG.
[0019]
As a result, in the process of producing a frozen beverage by cooling and stirring the syrup and dilution water supplied to the tank 1, the carbon dioxide gas supplied into the tank as fine bubbles from the air supply nozzle 16 diffuses. This is mixed with a sherbet-like beverage, thereby producing a carbonated frozen beverage containing a large amount of carbon dioxide gas and having a high volume expansion rate. It should be noted that surplus carbon dioxide that cannot be mixed in the beverage escapes from the tank 1 to the atmosphere after it escapes onto the liquid surface.
[0020]
【The invention's effect】
As described above, according to the configuration of the present invention, the atmospheric pressure release mounted on the dispenser for the non-carbonated frozen beverage can be used without adopting the sealed pressure vessel in the tank as the frozen manufacturing unit mounted on the dispenser body. by utilizing the tank shape, simply by retrofitting a carbon dioxide gas supply nozzle inwardly of that tank may be volume expansion rate is high and mouthfeel is also simple to produce a soft carbonated frozen beverages.
[0021]
In addition, a dispenser can be provided at a low cost because a simple structure open atmospheric pressure tank can be employed without mounting a pressure tank that has a complicated structure and is required to have a pressure resistance function, unlike the conventional carbonated frozen beverage dispenser.
