The amount of the powder raw material, that is, the amount of rotation of the discharger 17 is controlled by the control unit 53 so as to correspond to the rank set by the taste setting means. As described above, when the concentration of coffee (the amount of powdered raw material) is set as “rank 5”, the amount of sugar is set as “rank 4”, and the amount of milk is set as “rank 2”, first the coffee The amount of powder material (coffee powder) of “rank 4” obtained by subtracting the amount of “rank 1” previously reserved in the holding chute 22 from the set amount of “rank 5” is discharged 19 The amount of rotation (rotation time) of the discharger 17 is controlled so that the discharger 17 discharges the discharger. Then, the “rank 4” powder material discharged from the discharge port 19 is put into the mixing bowl 15 through the holding chute 22 together with the “rank 1” powder material. That is, in the mixing bowl 15, the “rank 1” and the “rank 4” are added and the powder material of the “rank 5” is supplied as set.

For sugar, the “rank 4” set
The amount of the raw material (sugar powder) in the amount of “rank 3” obtained by subtracting the amount of “rank 1” previously held in the holding chute 22 from the amount of the material is discharged from the outlet 19. The rotation amount (rotation time) of 17 is controlled. The “rank 3” powder material discharged from the discharge port 19 is put into the mixing bowl 15 through the holding chute 22 together with the “rank 1” powder material. That is, in the mixing bowl 15, the “rank 1” and the “rank 3” are added and the powder material of the “rank 4” is supplied as set.

As for the milk, the amount of the powder raw material (milk 1) corresponding to the amount of “rank 1” obtained by subtracting the amount of “rank 1” previously reserved in the holding chute 22 from the set amount of “rank 2” The amount of rotation (rotation time) of the discharge body 17 is controlled so that the powder (powder) is discharged from the discharge port 19.
The “rank 1” powder material discharged from the discharge port 19 is put into the mixing bowl 15 through the holding chute 22 together with the “rank 1” powder material. That is, in the mixing bowl 15, the "rank 1" and the "rank 1" are added, and the powder material of the "rank 2" as set is supplied.

Each of the powdery raw materials put into the mixing bowl 15 is mixed into the hot water swirling in the mixing bowl 15 to be stirred and mixed, whereby coffee having a set taste is prepared.

A strong amount of warm air is blown through the holding chute 22, and the steam in the mixing bowl 15 is discharged to the outside of the airframe 1 more efficiently through the exhaust path 40 by the warm air. It does not reach the outlet 19.

If only the steam in the mixing bowl 15 is exhausted, the temperature of the beverage (coffee) being stirred and mixed in the mixing bowl 15 is lowered, and the commercial value is impaired. Since a strong amount of hot air is blown through the hot air passage 34, a decrease in the temperature of the beverage can be suppressed.

After the beverage in the mixing bowl 15 is poured into the cup and the mixing bowl 15 is washed, each shutter 23 in each holding chute 22 rotates from a substantially vertical state to a substantially horizontal state. On hold shoot 2
2 is closed, and each canister 16 is closed.
The discharge motor 18 is driven for a predetermined time to rotate the discharge body 17, whereby the powder material in each canister 16 is discharged from the discharge port 19 into the holding chute 22 by an amount corresponding to “rank 1”. Is held on standby for the next sales operation. The powder raw material is discharged from the discharge port 19 of the canister 16 and the holding chute 22 is discharged.
When falling, the air in the holding chute 22 flows out of the air vent hole 22a in accordance with the fall, so that the powder material falls smoothly and quickly.

After the beverage is sold, the rotation of the exhaust fan 41 is stopped, and the rotation speed of the hot air fan 35 is switched from high speed to low speed.
4, the powder is constantly fed to the lower side of each shutter 23, and the heat of the hot air keeps the powder raw material in the holding chute 22 in a dry state, thereby preventing its solidification and quality deterioration.

As described above, a predetermined amount of powdered raw material is reserved in the holding chute 22 in advance, and the powdered raw material is put into the mixing bowl 15 at the time of selling the beverage, and the shortage of powder is supplied from the canister 16. Only the raw material is discharged, so that a predetermined amount of the powder raw material can be promptly supplied into the mixing bowl 15, and accordingly,
The desired beverage can be promptly provided to the user of the vending machine without shortening the process time of preparing the beverage and requiring a long waiting time.
