Each of the mixing balls 4 is equipped with a stirrer (not shown) for mixing the discharged raw material and hot water. Reference numeral 7 indicates a cup set on the bend stage 8. The cup 7 is discharged from the cup mechanism 9 shown in FIG. 2 by driving the cup motor 10 and set at a predetermined position of the bend stage 8 through the cup shooter 11. 12 is a bend stage 8 for the beverage mixed with the mixing ball 4.
It is a beverage pipe for guiding into the upper cup 7. 13 is
The exhaust fan motor exhausts heat so that heat is not accumulated in the vending machine, and 14 is a bucket for receiving a drink spilled on the bend stage 8.

When selling a coffee drink with the vending machine having the above-mentioned structure, the raw material canister 1 drives the corresponding raw material motor 2 to discharge hot water of coffee, sugar, and cream to the central mixing bowl 4. , The corresponding hot water valve 6 is opened for a predetermined time, hot water is discharged to the mixing ball 4, and the agitator in the mixing ball 4 is driven to mix the raw material and hot water, and the cup 7 is made into a coffee beverage. Discharge. As a result of mixing with a stirrer in this sales, air bubbles are generated in the coffee beverage, but since this foam disappears naturally after a while, this foam generation is particularly unpopular and unpleasant to the beverage purchaser. It's not about giving.

On the other hand, the control operation when selling a cappuccino drink will be described with reference to the time chart shown in FIG.
When the sales command is output at the time point t ₀ , first, the cup 7 is set on the bend stage 8, and 0.5 seconds after the time point t _{0 of the} sales command, the corresponding hot water valve 6 is opened for 2.7 seconds. Approximately 80 on the corresponding (center) mixing ball 4
While cc of hot water is discharged, the agitator in the mixing ball 4 is driven for 3 seconds after 1 second from the time point t ₀ ,
Further, 1.5 seconds after the time point t ₀ , the coffee raw material motor 2
Is driven for 0.6 seconds, and the sugar raw material motor 2 is driven for 0.85 seconds, so that 1.8 is applied to the mixing ball 4.
g of coffee raw material and 6 g of sugar are discharged. Then, the raw materials are mixed by a stirrer in the mixing ball 4 and discharged to the cup 7.

1.8 seconds after the stirring motor is stopped, hot water is discharged again, and the stirring motor is driven after the discharge.
This operation is for washing out the raw materials adhering to the mixing ball 4 and the beverage pipe 12, and the washed liquid is also discharged to the cup 7.

Now, 1.0 second after the driving stop time t _{1 of the} second stirring motor (for coffee), the hot water valve 6 is opened for 0.7 seconds, and 20 cc is placed on the second mixing ball 4 from the right.
Hot water is discharged, and 1.2 seconds after the time point t ₁ , the stirring motor in the mixing ball 4 is driven for 0.5 seconds,
Further, 1.4 seconds after the time point t ₁ , the whipped cream raw material motor 2 is driven for 0.3 seconds, and 5 g of whipped cream is discharged to the mixing ball 4. As a result, the whipped cream discharged to the mixing ball 4 is discharged to the cup 7 while being mixed with hot water.

1.8 seconds after the time t ₂ when the stirring motor (for whipped cream) is stopped, 20 cc of hot water is discharged to the mixing ball 4 and 0.2 seconds after the discharge is stopped. By driving the stirring motor, the whipped cream pipe is washed away and the cup 7
Is discharged. At this time point t _3, all the sales operations are completed.

[0009]

However, in the above control operation, the discharge of the coffee beverage to the cup 7 ends at time t ₁ , but at this time, the bubbles generated by the agitation still remain. As a result of discharging the whipped cream before the bubbles disappear, the high-viscosity whipped cream wraps the bubbles, and the bubbles do not disappear forever, so there is a problem that the product is not well-made and the value as a product is lost. To prevent this, the timing of the whipped cream discharge should be further delayed, and the whipped cream should be added after the air bubbles disappear, but in that case, the selling time is prolonged and the purchaser takes out the coffee beverage before the cream discharge. Such a problem occurs.

The present invention has been made in order to solve the above-mentioned problems, and provides a beverage cooking control device capable of providing a good-quality cappuccino beverage by defoaming before the discharge of whipped cream. With the goal.

DISCLOSURE OF THE INVENTION The present invention relates to a cup-type vending machine which discharges a coffee beverage obtained by mixing coffee raw material and hot water into a cup and then further discharges a whipped cream. A beverage cooking apparatus, comprising an air pump or valve, wherein the air pump or valve is driven for a predetermined time after the coffee beverage is discharged into the cup and before the whipped cream is discharged, and air or carbon dioxide gas is introduced into the cup. It is characterized by spraying bubbles on the liquid surface of the coffee drink.

[0012]

Immediately after the coffee beverage is discharged into the cup, air bubbles are generated on the liquid surface of the coffee beverage due to the mixing and the discharge. Therefore, an air pump or a valve that releases gas from a carbon dioxide gas cylinder is operated for a predetermined period of time to blow air or carbon dioxide gas onto the liquid surface of the coffee beverage to crush the bubbles, and then whipped cream is discharged. Eliminates the wrapping of air bubbles in the cream.
