Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup vending machine and a powder dispenser for discharging a beverage using powder raw material and hot water.

FIG. 1 shows a schematic view of a beverage pipe in a powder dispenser for selling a cup beverage based on one cup of powder raw material. In the figure, three raw material boxes 1 each store powdered raw materials such as sencha, hojicha, and oolong tea.
Raw material motors 2 for discharging the respective raw materials are provided, and the raw materials discharged from the raw material box 1 by the driving of these raw material motors 2 are respectively supplied to the corresponding stirring balls 4 through the shooters 3.

The water stored in the cassette tank 5 is kept constant in the hot water tank 6 by driving the pump 7 based on the detection of a water level switch (not shown) provided in the hot water tank 6 and opening the hot water tank water supply valve V1. Water at the water level is stored. The water in the hot water tank 6 is heated by the heater 8 to hot water having a constant temperature. Further, based on the detection of the water level switch (not shown), the pump 7 is driven and the cold water tank water supply valve V2 is opened, so that the cold water tank 9 stores water at a constant water level. A cooler 11 to which a refrigerant is supplied from a cooling device 10 is provided in the cold water tank 9, and the water in the cold water tank 9 is cooled to a constant temperature.

At the time of selling hot beverages, hot water in the hot water tank 6 is discharged to the agitating bowl 4 through the hot water supply pipe 12 by opening one of the hot water valves V3 to V5. As a result, the raw material and hot water supplied to the stirring ball 4 are mixed and discharged as hot beverage into the cup 14 through the beverage supply pipe 13. On the other hand, when selling cold beverages, the cooling water in the cold water tank 9 is cooled by the cold water valves V6 to V6.
One of the bottles 8 is opened and discharged into the stirring bowl 4 through the cold water supply pipe 15 to be supplied to the cup 11 as a cold beverage.

In the powder dispenser having such a structure, the raw material motor 2 is driven for t seconds in advance for each raw material, and the discharge amount Q (g) resulting therefrom is measured with a balance several times.
The average value S of the discharge amount Q / t (g / sec) per unit time is input as data, and at the time of sale, when the powder raw material amount to be discharged into the cup beverage is W (g), W / S The raw material motor 2 is driven according to the obtained raw material discharge time (seconds).

[0006]

However, in this method, it is necessary to perform the discharge / measurement operation for one raw material a plurality of times for three raw materials, which requires a lot of labor and time. Also, in this type of powder dispenser, the unit of the energization time of the raw material motor 2 is not seconds, but 1 second is 10 seconds.
It is managed with a numerical value of 0, and it is unfamiliar with such numerical notation, and the discharge amount may differ even with the same numerical value (discharge time) due to the difference in the type of raw material. Correspondence is not clear. For example, if the discharge time is changed from 0.5 second (50 in the unit) to 0.52 second (52 in the unit), it can be intuitively estimated how much the discharge amount will increase. It doesn't matter how much the change from 50 to 52 increases. Therefore, when changing the amount of hot water (or the amount of cold water), it is necessary to adjust the amount of raw material according to the amount of increase or decrease, but the work of increasing or decreasing the amount of time is also troublesome. As described above, the conventional setting work has a problem that it cannot be easily performed unless the work content is sufficiently mastered.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an apparatus capable of easily setting the amount of raw material.

Here, as Example 1, the setting in the case of sencha, which is a hot beverage, will be described. Standard hot water amount D = 100cc,
When the standard raw material amount E and the standard raw material amount discharge time F (both are known values), (E / B) / F is calculated several times, and the average value k
= 4.95, the raw material discharge time T is T = (A / B) * (C / D) * (1 / k) = (0.9 / 0.21) * (100/100) * (1 / 4.95) = 0.86 seconds. (Example 2) In the case of Hojicha as a hot beverage Standard hot water amount A = 90 cc Bulk specific gravity B = 0.21 g / cc Standard raw material amount E and standard raw material amount discharge time F (both known values), (E / B) / F is calculated several times, and the raw material discharge time T when the raw material discharge amount A = 1.0 g and the hot water amount D = 120 cc is T = (A / B), (C / D), (1 / k) = (1 / 0.21), (120/100), (1 / 4.80) = 1.19 seconds.

As described above, according to the present invention, the discharge data of the dispenser can be set simply by the discharge amount (g) instead of the discharge amount per unit time, which facilitates the setting work. . Further, the increase / decrease of the raw material can be changed by operating the increase / decrease key operation in units of%, so that an accurate raw material discharge time can be obtained. Furthermore, when the amount of hot water or the amount of cold water is changed, the raw material discharge time is automatically calculated, so that a beverage having a uniform concentration can always be provided.
