Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a beverage manufacturing method in a vending machine that mixes liquid and powder raw materials to create a beverage.

(Prior Art) Conventionally, as a method for making a beverage by mixing liquid and powder raw materials at the time of dispensing a beverage in a beverage vending machine, for example, there is a method as shown in Japanese Utility Model Application Publication No. 100205/1983. In many cases, liquid and powder raw materials are mixed in a mixing container or supply trough, and the mixture is poured into a cup.

However, with this method, liquids such as cold or hot water are temperature sensitive due to temperature differences with the mixing container or supply trough, making it difficult to provide a beverage at a constant temperature, and powdered raw materials are Although it is washed away by liquid,
Due to their nature, powdered raw materials tend to stick and remain in the mixing vessel or feed trough and are therefore unhygienic unless additional cleaning means are provided. In addition, the above publication describes a method for supplying a powder raw material in the middle while supplying a liquid, and a method for supplying a powder raw material in the middle while supplying a liquid, regarding the supply of a liquid and a powder raw material. However, in both cases, liquid and powder raw material are supplied at the same time, so the powder raw material is likely to be scattered around by the splashing of the liquid.

In addition, as shown in Japanese Utility Model Publication No. 39-32623, a predetermined amount of liquid and powder raw material is supplied to a supply trough, which is led to a stirrer, and the remaining amount of liquid is supplied to the stirrer. A known method is to mix the mixture and pour it into a cup.

Although this method achieves sufficient mixing, it promotes mixing outside the cup, and the above-mentioned problems still remain.

For this reason, it is preferable to supply and mix the liquid and powder raw materials directly into the cup without using a mixing container or a supply trough. As this method, as shown in Japanese Utility Model Publication No. 53-42637,
A method has been proposed in which liquid is supplied into a cup containing powdered raw materials in advance and mixed within the cup.

According to this method, the above-mentioned temperature and hygiene problems can be solved, but with this method, the powdered raw materials stored in advance are blown up by the jetting pressure of the liquid, causing them to get dirty or get stuck inside the cup. It tends to stick and is difficult to remove.

Furthermore, as shown in Japanese Utility Model Publication No. 43-28895, a method has also been proposed in which liquid and powdered raw material held in a film-like packaging material are supplied and mixed in a cup when the beverage is served.

However, in this case, if the liquid and the powder raw material are supplied into the cup at the same time, that is, if the powder raw material is supplied while the liquid is being continuously supplied, the liquid and the powder raw material do not mix well and the liquid level increases. The powdered raw material floating on the top is likely to scatter outside the cup along with water droplets, and therefore the liquid supply flow rate cannot be increased, and it is necessary to supply a constant quantity over time, and the mixing effect is not sufficient. do not have. In addition, a fixed amount of powdered raw material is sealed in a film-like packaging material, and each filling section is opened one after another to take out the powdered raw material, so the powdered raw material must be packaged in a special form. figure,
A dedicated opening device is also required.

For this reason, it is desirable to use a general-purpose canister that feeds out a fixed amount of powdered raw material in order to supply the powdered raw material, but if you feed the powdered raw material directly from the canister into the cup, is close to the cup, and as a result, moisture from the liquid supplied into the cup tends to enter the outlet of the canister, causing the powder raw material to solidify and hinder the discharge of the powder raw material.

(Problems to be Solved by the Invention) As mentioned above, in the conventional beverage manufacturing method in which liquid and powdered ingredients are mixed in a cup, there are problems such as adhesion of powdered ingredients, scattering, and insufficient mixing. .

The present invention was conceived in view of the above-mentioned problems, and aims to reliably mix and agitate liquid and powder raw materials within a cup, while also preventing the surroundings from being contaminated. .

Furthermore, a waste liquid detection switch 43 is provided above the waste liquid container 42 , and a detection float 45 suspended by a chain 44 of the waste liquid detection switch 43 is inserted into the waste liquid container 42 .
Further, an overflow pipe 46 is connected from the upper part of the liquid tank 22 to the waste liquid container 42 .

Although not shown, a coin sales mechanism is provided inside the door body 2, and a coin sales mechanism is provided inside the door body 2.
A coin slot and on-sale indicator lamp are provided on the front of the machine.

In such a device, a cup 5 made of paper or the like is stored in a cup storage case 4 of a cup supply device 3.
Canister 1 is stored in a stacked state.
Powder raw materials are stored in one raw material case 12. In addition, a liquid supply port 3 is provided in the liquid tank 22 of the liquid supply device 21.
5, a liquid such as water is injected through a liquid supply pipe 32 via a strainer 34 and a solenoid valve 33. On this occasion,
The liquid enters the upper part of the liquid tank 22 and is led to the lower part through the through hole 27 of the buffle plate 28, so that there is less mixing of the fresh liquid with the lower cooling liquid. Also, depending on the amount of liquid in the liquid tank 22, the liquid supply detection float 31 attached to the movable lever 30 of the liquid supply detection switch 29 moves up and down, turning the liquid supply detection switch 29 on and off to open and close the solenoid valve 33. However, the liquid in the liquid tank 22 is always injected in a constant amount. Furthermore, the compressor 26 of the cooling cycle is driven, and the liquid in the liquid tank 22 is cooled by the evaporator 23.

When a predetermined amount of coins is inserted and the operation button is operated, the cup feeder 5 of the cup feeder 3 is activated and one cup 51 at the bottom of the cup storage case 4 is dispensed. It is disposed at a predetermined position of the cup receiving portion 7 via the canister 11, that is, directly below the tip of the outlet 13 of the canister 11.

Next, the electromagnetic valve 36 and pump 38 of the liquid tank 22 are activated, and a certain amount of the cooling liquid in the liquid tank 22 is injected into the bottom of the cup 51 from the liquid supply nozzle 39 via the liquid supply pipe 37. Pour enough amount to cover the powder raw material to be used, for example, about twice the amount of the powder raw material.

Next, the shutter 18 of the canister 11 is opened, the motor 15 is activated, the feeding body 14 is rotated, and a certain amount of the powder raw material is fed out from the outlet 13 located directly above the cup 51 of the cup receiver 7. directly into the liquid inside. At this time, since the liquid in the cup 51 is almost stationary, the dropped powder raw material sinks into the liquid and
Some of it dissolves. Furthermore, the agitator gear 16 is rotated by the rotation of the feeder body 14, and the agitator 17 is operated to stir the powder raw material in the raw material case 12. In addition, since the liquid supply is stopped when this powdered raw material is introduced, moisture is absorbed into the canister.
It does not adhere to the outlet port 13 of No. 1 or enter the inside.

Then, the electromagnetic valve 36 and the pump 38 of the liquid tank 22 are operated again, and the pump 38 injects the pressurized liquid into the cup 51 together with the amount previously injected into the cup 51 in an amount sufficient to reach a predetermined sales amount. At this time, since the liquid supply nozzle 39 is arranged obliquely from above the cup 51, the liquid is supplied to the cup 51.
Insert the cup 5 from diagonally above the center of the cup 51.
The liquid is spouted under pressure toward the inner wall surface of the cup 51, thereby causing the liquid to swirl vertically within the cup 51.
That is, the powder material at the bottom of the cup 51 is rotated in such a way that it is pushed up above the cup 51,
The powder raw material is mixed with the liquid and stirred.

The above operations are shown in FIGS. 3 to 5.

As an example, when making a beverage of about 250 c.c., for example, pour about 40 c.c. of liquid into the cup 51, which is about twice the amount of the initial powder raw material, and then pour the powder raw material into the cup 51. Pour about 18g, then add about 18g of liquid.
Inject 190c.c.

〔Effect of the invention〕

According to the present invention, first, a fixed amount of liquid is supplied into the cup, and then the powdered raw material is introduced into the cup, and the powdered raw material is allowed to sink into the liquid in an almost stationary state. Create a state where it is almost hidden, and let the two blend together in advance.
Then, the pump pressurizes the liquid and supplies it to the entire volume, so the powder material does not stick to the inside of the cup, and the liquid is supplied into the cup from diagonally above the center of the cup. As the pump pressurizes and ejects the liquid toward the wall, the liquid swirls vertically within the cup, pushing the powder material at the bottom of the cup upwards. Since the moving distance becomes longer, it is possible to provide a beverage that dissolves well, maintains a constant concentration in the upper and lower portions, and reliably mixes and stirs the powdered raw material and liquid.

Furthermore, since the powdered raw material is in the liquid that is initially supplied within the cup, the powdered raw material does not scatter outside the cup, and it is possible to prevent the surrounding area from being contaminated.

Furthermore, since the supply of liquid is stopped when powder raw materials are introduced, moisture does not adhere to the canister outlet or enter the interior.
It's convenient.
