Description

  The present invention relates to a beverage preparation nozzle for preparing a beverage in which a stock solution is diluted with a diluent.

Microorganisms are difficult to grow in stock solutions such as syrups for juices that contain high concentrations of sugar, which is a nutrient source for microorganisms, but beverages that are diluted with diluted solutions have moderately diluted sugar concentrations. Therefore, microorganisms are easy to grow.
For this reason, when the stock solution and the diluted solution are mixed and diluted in the nozzle, there is a possibility that a beverage with a moderately diluted sugar concentration adheres to the nozzle and remains in the nozzle, and various germs may grow, and the nozzle is frequently washed. There is a problem that takes time.
In order to solve this problem, in the conventional beverage preparation nozzle, a stock solution nozzle for discharging the stock solution and a dilution solution nozzle for discharging the dilution solution are provided independently so that the diluted beverage does not remain in the nozzle. The undiluted solution discharged from the undiluted solution nozzle and the dilute solution discharged from the diluting solution nozzle are mixed by colliding with each other in the air apart from any nozzle (see, for example, Patent Document 1).

JP 2008-189327 A

However, in the conventional beverage preparation nozzle, splashes are generated at the time of collision between the stock solution and the diluted solution, and the periphery of the nozzle tends to become dirty, and air may be mixed at the time of the collision between the stock solution and the diluted solution to impair the taste of the beverage. is there.
The present invention has been made in view of the above circumstances, and it is possible to suppress the adhesion of the diluted beverage in the nozzle, while making it difficult to get dirty around the nozzle and less likely to impair the taste of the beverage. An object is to provide a nozzle.

  1st characteristic structure of this invention is a drink preparation nozzle for preparing the drink which diluted the undiluted solution with the dilution liquid, Comprising: The 1st front-end | tip part which the 1st discharge port which discharges undiluted solution opens downward is provided. A first nozzle member, and a second nozzle member provided with a second tip portion in which the second discharge port for discharging the diluent opens downward, and the first tip portion is directed downward from the second discharge port. The second discharge port is formed in an annular shape surrounding the first tip, and the first discharge port is disposed downstream of the second discharge port in the discharge direction. There is in point.

In the beverage preparation nozzle of this configuration, the first tip portion where the first discharge port for discharging the stock solution opens downward is disposed so as to protrude downward from the second discharge port for discharging the diluent, Since the discharge port is formed in an annular shape surrounding the first tip, the first discharge port and the second discharge port can be arranged close to each other in the discharge port radial direction.
In addition, since the first discharge port is disposed downstream of the second discharge port in the discharge direction, the diluted liquid discharged from the second discharge port is located outside the second nozzle member along the outer periphery of the first tip portion. The first discharge port can be exposed to the flowing down diluent.
Therefore, if it is a drink preparation nozzle of this structure, an undiluted | stock solution can be merged and mixed in the diluent which flows along the outer periphery of a 1st front-end | tip part on the outer side of a 1st nozzle member and a 2nd nozzle member. Therefore, while making it possible to suppress the residue of the diluted beverage from adhering to the nozzle, it is difficult for droplets to form, and it is difficult for air to enter the diluted beverage, making it difficult for the periphery of the nozzle to become dirty, and the taste of the beverage. There is little risk of damage.
In addition, since the first discharge port is disposed downstream of the second discharge port in the discharge direction, there is no possibility that the stock solution discharged from the first discharge port enters the second nozzle member.
Therefore, the second nozzle member is effectively cleaned with the diluent that passes through the second nozzle member, and the frequency of cleaning the second nozzle member can be reduced.

  The second characteristic configuration of the present invention is that the first tip portion is formed in a convex curved surface shape protruding toward the downstream side in the ejection direction.

If it is this structure, it will become easy to make the dilution liquid discharged from the 2nd discharge port flow smoothly toward the 1st discharge port side along the 1st front-end | tip part formed in the convex curve shape. It is easy to be surely exposed to the diluent flowing down the discharge port.
Moreover, when it is desired to open a plurality of the first discharge ports, the surface area of the first tip portion can be secured large, and the interval between the adjacent first discharge ports can be set large, and the strength of the first tip portion can be set. Easy to secure.

  A third characteristic configuration of the present invention is that a plurality of the first discharge ports are open to the first tip portion.

In this configuration, since the plurality of first discharge ports are opened at the first tip portion formed in the convex curved surface shape, at least one of the plurality of first discharge ports is opened obliquely downward. And can be placed in the diluting liquid flowing down.
Therefore, it is possible to give the stock solution discharged from the first discharge port a velocity component in a direction crossing the flow direction of the diluent, and to promote collision between the stock solution and the diluent in the diluent. It is easy to dilute uniformly.

It is a partial cross section side view which shows a drink preparation nozzle. It is sectional drawing which shows the front-end | tip part of a drink preparation nozzle. It is a front view which shows the front-end | tip part of a drink preparation nozzle.
