Description

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

  Conventionally, a beverage dispenser generally has a structure in which a beverage in which a syrup and a diluent (diluted water or carbonated water) are mixed in a mixing nozzle flows down to a cup (beverage container). In the case of such a structure that mixes beverages, diluted syrup adheres to the inner wall surface of the mixing nozzle and remains, so there is a risk that germs will easily propagate, and daily nozzle cleaning is essential for hygiene management. Met. Further, since the syrup nozzle cannot be removed, it has been difficult to clean it.

  On the other hand, since it is difficult to perform daily nozzle cleaning in a cup-type vending machine, the nozzle that discharges syrup and the nozzle that discharges diluent are each independent, and the discharged syrup and diluent are mixed on the inner wall surface of the cup. It is said. In the case of this method, the syrup that remains in the syrup nozzle discharge port and is not diluted can maintain a strong acidity (pH <7) concentration at which miscellaneous bacteria do not propagate (see, for example, Patent Document 1 and Patent Document 2).

  Thus, since the nozzle of the cup type vending machine is provided with the syrup nozzle and the diluting liquid nozzle independently, there is no possibility that various germs propagate.

  However, since the cups used in the beverage dispenser have different shapes and the positions where the cups are placed are not constant, it is not possible to adopt a method of mixing syrup and diluent on the inner wall surface of the cup.

  There is also a method in which the syrup discharged from the nozzle and the diluent are directly mixed and allowed to flow down into the cup. However, since this method does not allow the syrup and diluent to mix sufficiently, the beverage at the bottom of the cup is syrup. The concentration is high (for example, sugar content 14), the upper beverage has a low syrup concentration (for example, sugar content 6), and the syrup concentration is uneven (for example, sugar content difference 8).

  The present invention has been made in order to solve the above-described problems. A uniform syrup concentration is obtained in a beverage dispenser, a cup-type vending machine, or the like that supplies a diluted beverage by mixing a syrup and a diluent. An object of the present invention is to provide a beverage supply device that can supply the beverage and hygienically manage the nozzle.

In order to achieve the above object, a beverage supply device according to claim 1 of the present invention includes a beverage nozzle comprising a beverage nozzle that collides and mixes a syrup and a diluted solution of diluted water and / or carbonated water in the air. A feeding device,
The beverage nozzle is connected to a syrup pipe and discharges syrup, and is connected to a diluting liquid connecting pipe in which the diluting water pipe and the carbonated water pipe are merged, and is a diluting liquid consisting of diluting water and / or carbonated water. A diluent nozzle for discharging
A buffer space for absorbing the expansion of carbonated water is provided between the diluent connecting pipe and the diluent nozzle.

  Moreover, the beverage supply apparatus according to claim 2 of the present invention is characterized in that, in claim 1 described above, a pressure decompression section for decompressing carbonated water is provided on the downstream side of the buffer space.

  According to the first aspect of the present invention, since the undiluted syrup that remains in the discharge port of the syrup discharge nozzle can maintain a strong acidity (pH <7) concentration, there is no possibility of various bacteria breeding, and the nozzle is hygienic. In addition, even when carbonated water foams and expands, the expansion is absorbed in the buffer space, so that a weak carbonated beverage is supplied by the beverage supply device. In addition, the carbonated water discharged from the diluent nozzle can be prevented from scattering.

  According to the invention of claim 2, it is possible to suppress a decrease in the volume of carbonated water supplied to the cup by reducing the pressure of carbonated water.
