Description

  The present invention relates to a beverage nozzle of a beverage supply device such as a beverage dispenser or a cup type vending machine that supplies a diluted beverage by mixing a liquid raw material and a diluent.

  Conventionally, a beverage dispenser generally has a structure in which a beverage in which a liquid raw material (hereinafter referred to as “syrup” as appropriate) and a diluent (diluted water or carbonated water) are mixed in a mixing nozzle flows down to a cup (beverage container). It is used. In the case of a structure in which the syrup and the diluting liquid are mixed in the mixing nozzle in this way, the diluted syrup adheres to the inner wall surface of the mixing nozzle and remains, so that there is a possibility that various bacteria may easily propagate. Nozzle cleaning was essential for hygiene management.

  On the other hand, since it is difficult to perform daily nozzle cleaning in a cup-type vending machine, the nozzle that discharges the syrup and the nozzle that discharges the diluent are separated and made to collide with the inner wall surface of the cup. To mix. In the case of this mixing method, the undiluted syrup that remains in the syrup nozzle outlet can maintain a strong acid concentration at which no germs grow.

As described above, since the syrup nozzle and the diluting liquid nozzle are provided separately from each other in the nozzle of the cup type vending machine, there is no possibility that various germs propagate.
However, the cups used in beverage dispensers are different in size and shape, and the position where the cup is placed is not constant, and the positional relationship between the cup inner wall surface and the nozzle is not fixed, so the syrup and dilution on the inner wall surface of the cup It was not possible to adopt a method of mixing by colliding with the liquid.

  In order to solve such an inconvenience, for example, in the beverage supply device disclosed in Patent Document 1 filed by the present applicant, a plurality of syrup nozzles are used for one dilution liquid nozzle that discharges the dilution liquid obliquely downward. In which the syrup discharged from any one of the plurality of syrup nozzles and the diluent discharged from the diluent nozzle collide with each other in the air and mixed. Is fed down to the cup.

  However, in the beverage supply device of Patent Document 1, since a plurality of syrup nozzles are arranged in the vertical direction with respect to one diluent nozzle, the plurality of diluent discharge ports of the diluent nozzle are arranged. Since the syrup outlets of the syrup nozzles are different from each other in the syrup outlets, if the beverage is mixed by colliding the syrup and the diluent in the air, the syrup is discharged by each syrup nozzle that has discharged the syrup. There is a problem that the quality of the beverage (brix and forming) supplied to the cup is not constant because the state of collision in the air with the diluted solution is different and the mixing condition of the beverage is not uniform.

  That is, the beverage supplied to the cup is required to have a uniform Brix (BRIX) representing the beverage concentration (sugar content) in each of the upper and lower layers in the cup, but the syrup and the diluent are mixed uniformly. Otherwise, the brix of the beverage supplied to the cup will be uneven. This is because concentrated syrups used in beverage dispensers have specific concentrations and viscosities depending on the type, and particularly concentrated syrups that are highly viscous are difficult to mix with the diluted solution, and the syrup-flavored and thin layers are separated. This is because it has the property of being easily mixed.

  In addition, in the case of a beverage with a strong foaming property, excessive foaming (foaming phenomenon) occurs in the cup, resulting in a so-called fizzy carbonated beverage, and the foam overflows from the cup and the outer surface of the cup. Sometimes it gets wet.

  The present invention has been made to solve the above-described problems, and it is possible to supply a high-quality beverage without unevenness of taste by uniformly mixing a liquid raw material and a diluent and supplying them to a cup, and It is an object of the present invention to provide a beverage nozzle of a beverage supply device capable of supplying a beverage in a high quality finished state while suppressing the separation and release of carbon dioxide gas generated when the beverage is supplied to a cup and excessive forming.
