As a conventional technique, for example, as disclosed in Japanese Patent Laid-Open No. 63-30997, a method of stirring raw materials in a cup has been proposed.

 This conventional structure will be described below with reference to FIG.

A flat spray nozzle 1 is connected to a pressurized hot water supply hose 2a and a cold water hose 2b which supply hot water pressurized by a pressure pump (not shown). Then, pressurized hot water or cold water is injected into the cup 3a placed below the flat spray nozzle 1 and filled with the powder material 3 in advance.

Further, the flat spray nozzle 1 is oscillated by the drive device 4 in the direction of arrow E. 5 is cup 3a
The nozzle is fixed inward, is connected to the hot water supply hose 6, and supplies hot water that is not pressurized into the cup 3a. An ice shooter 7 supplies ice into the cup 3a during cold beverage production.

In the cup raw material agitating device configured as described above, when the cup 3a to which the powder raw material 3 is supplied is set by the sales instruction, the flat spray nozzle 1 is swung by the drive device 4 and, at the same time, pressurized hot water is supplied. Hot water is injected from the hose 2a through the flat spray nozzle 1.

As a result, the powder raw material 3 in the cup 3a is agitated by the water flow, mixed with the hot water, dissolved in the hot water, and becomes a beverage.

After the dissolution is completed, the above pressure injection is stopped and the dilution is subsequently performed. During hot beverage production, hot water is supplied from the hot water supply hose 6 through the fixed nozzle 5 into the cup 3a, and when it reaches a predetermined amount, the hot water is stopped and the preparation of the beverage is completed.

During cold beverage production, after the injection of pressurized hot water from the flat spray nozzle 1 is stopped, cold water is supplied into the cup 3a through the cold water hose 2b, ice is supplied from the ice shooter 7, and the supply is stopped when the predetermined amount is reached. Then, the cold beverage preparation is completed.

Shorter than when supplying a large cup size with a large amount of raw material supplied to the inside, and the amount of pressurized hot water supplied from the pressurized hot water supply spray nozzle is smaller than that of a large cup size with a large amount of raw material supplied into the cup. Then, a specified amount of hot water is supplied into the cup. As a result, the raw material and hot water are agitated by a small amount of water flow compared with a large cup size in which the amount of raw material supplied into the cup is large, and the raw material and hot water are mixed and dissolved with the hot water to form a beverage. Next, ice is supplied and cooled, and then cold water is supplied and stirred to provide one cup of beverage in a shorter time than in the case of a large cup size in which a large amount of raw material is supplied into the cup. . When the material is supplied in a large cup size with a large amount of raw material supplied to the cup, the opening time of the valve connected to the spray nozzle for pressurized hot water supply by the flow rate adjustment device is set to a small cup size with a small amount of raw material supplied into the cup. The amount of pressurized hot water supplied from the pressurized hot water supply spray nozzle is increased compared to the case of a small cup size with a small amount of raw material supply into the cup, and the specified amount of hot water is supplied in the cup. To supply. As a result, the agitation property of the raw material and the hot water is promoted by a large amount of water flow as compared with the case of a small cup size in which the amount of the raw material supplied into the cup is small, and the raw material and hot water are mixed and melted to form a beverage. Next, a large amount of ice is supplied and cooled as compared to the case of a small cup size with a small amount of raw material supply into the cup, and then cold water is supplied and stirred to provide one cup of beverage Is.

As described above, when using a small cup size with a small amount of raw material supplied to the cup, the flow controller adjusts the opening time of the valve connected to the spray nozzle with a small amount of hot water supply per unit time for pressurized hot water. By making it shorter than when using a large cup size with a large amount of raw material supplied to
It is possible to shorten the sales time of a drink for a cup as compared with the case of a large cup size in which a large amount of raw material is supplied into the cup. In addition, when the size of a large cup is large and the amount of raw material supplied to the cup is large, the opening time of the valve connected to the spray nozzle for pressurized hot water supply by the flow rate adjusting device is set to a small cup size with a small amount of raw material supplied to the cup. By making the length longer than that, it is possible to increase the amount of pressurized hot water to be supplied to the cup as compared with the case of a small cup size in which the amount of raw material supplied into the cup is small, and to promote the dissolution and mixing of the raw materials.
That is, by adjusting the amount of hot water supplied from the spray nozzle according to the difference in the solubility due to the difference in the supply amount of the raw material caused by the different cup sizes, it is possible to surely dissolve in a short time. Furthermore, a special device for rocking the spray nozzle when stirring the raw material is not required, and the number of constituent parts is small and the installation area can be small.
