First, when the product selection button D is not pressed, the coffee brewer 40 is in a stand-by state for sale, and the cylinder 42 is separated from the filter block 43 and the filter 46. When coins are inserted by the user or the like from this sales standby state and an arbitrary product selection button D is pressed and notified through the vending machine control unit 90, the extraction control unit 91 drives the lifting means 45 to As shown in FIG. 7A, the filter block 43 is moved upward and fitted into the cylinder 42 via the filter 46. Thereafter, the extraction control unit 91 pulverizes the coffee beans supplied from the coffee bean canister 66 by driving the mill 67 to form ground raw beans in the form of a powder raw material. 42 to the inside. When a preset amount of ground beans is put into the cylinder 42, the extraction control unit 91 supplies hot water stored in the hot water tank 60 while the shower unit 41 is heated by the shower hot water heater 47. The hot water is heated to a desired temperature (for example, 90 ° C. or higher) with respect to the coffee raw material and supplied in a shower form.

  When the hot water supplied through the shower unit 41 reaches a preset amount with respect to the coffee raw material in the cylinder 42, the extraction control unit 91 drives the tube pump 52 as shown in FIG. In this case, the coffee raw material and hot water stored in the cylinder 42 are mixed by supplying air from the filter block 43 to the inside of the cylinder 42 through the air supply and extraction conduit 51. Stir the body. As a result, flavor and umami are extracted from the coffee raw material into hot water, and a coffee beverage is generated inside the cylinder 42. In this case, since the cylinder 42 is kept at a suitable temperature by the cylinder heater 48 and the filter block 43 is kept at a suitable temperature by the filter block heater 49, the temperature of the mixture of the coffee raw material and hot water can be maintained to enhance the steaming effect, It is possible to extract high-quality beverages that sufficiently extract flavor and umami while suppressing undesirable components such as miscellaneous taste, astringency, and bitterness.

Thereafter, as shown in FIG. 7C, the extraction controller 91 drives the tube pump 52 (in the embodiment, rotationally drives in the clockwise direction), and the coffee drink generated inside the cylinder 42 is filtered. 46 is supplied to the mixing bowl 68 through the air supply / extraction pipe 51. Even when the coffee beverage is supplied to the mixing bowl 68 through the air supply / extraction pipe 51, the air supply / extraction pipe 51 is heated by the beverage pipe heater 50, so that the temperature of the coffee beverage extracted at a high temperature is high. And can be supplied to the mixing bowl 68.
After the supply of the coffee beverage to the mixing bowl 68 in this way, as shown in FIG. 7 (d), the elevating means 45 is driven to move the filter block 43 downward, and a certain amount of the filter 46 is fed out and used. The later filter 46 and the extracted soot adhering thereto are discarded in the soot bucket 71. In addition, the waste liquid pinch 53 is opened, and the waste liquid is discharged into the bucket 71.

According to the cup-type beverage vending machine 1 according to the embodiment described above, the ambient temperature of the installed beverage is lowered, and the temperature inside the cup-type beverage vending machine 1 is lowered (for example, 30 ° C. or less). ), Even if the hot water supplied from the hot water tank 60 falls below a temperature suitable for extracting a coffee beverage (for example, 90 ° C. or more) due to heat loss when flowing through the hot water pipeline 62. Since it is reheated by the heat generated by the hot water heater 47, it becomes a temperature suitable for extracting the coffee beverage, and the shower-like hot water supplied from the shower unit 41 has a temperature suitable for extracting the coffee beverage. It will spread evenly and uniformly as “steaming water”. Since the cylinder 42 is kept at a suitable temperature by the cylinder heater 48 and the filter block 43 is kept at a suitable temperature by the filter block heater 49, the coffee material in the cylinder 42 is immersed in "steaming water" at a temperature suitable for extracting coffee beverages. By being sufficiently steamed, it is possible to extract a high quality beverage that sufficiently suppresses unfavorable components such as miscellaneous taste, astringency, and bitterness and sufficiently brings out flavor and umami. When the extracted coffee beverage is supplied to the mixing bowl 68 through the air supply and extraction conduit 51, the air supply and extraction conduit 51 is heated by the beverage conduit heater 50, so that the coffee extracted at a high temperature is used. The temperature of the beverage can be maintained and supplied to the mixing bowl 68. Furthermore, since the voltage applied to each heater is turned on and off according to the internal temperature, power can be saved. As a result, it is possible to sell beverages that have been extracted by sufficiently extracting flavor and umami while suppressing undesirable components such as miscellaneous taste, astringency, and bitterness, and can further save power A beverage beverage vending machine can be provided.

  In the above-described embodiment, a cup-type beverage vending machine provided with an apparatus for extracting coffee beverages obtained by grinding coffee beans into powdered raw materials is illustrated, but the present invention uses beverages from other powdered raw materials.
