Abstract

PROBLEM TO BE SOLVED: To prepae a beverage having stable concentration by detecting the temperature of a hot water to be supplied to an extraction room and setting up extraction conditions based on the detected temperature. SOLUTION: When a vending signal is outputted from a main control part 9, a beverage preparation control part 8 allows a beverage preparing part 2 to execute a beverage extraction control, i.e., a series of processes such as a steaming process, an agitation process and an extraction process. At the time of the steaming process and the agitation process, the control part 8 controls steaming time, agitation time and agitation strength based on contents stored in a memory by a temperature sensor in an extraction room 20d. Since extraction conditions such as steaming time, agitation strength and agitation time are changed based on the temperature of hot water supplied to the extraction room 20d, a coffee beverage having stable concentration can be served even when the temperature of hot water for extraction is different. Since correction values are stored in the memory differently from a program, the correction values can easily be changed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage extracting apparatus applied to a cup-type vending machine for extracting coffee, black tea, oolong tea, green tea and the like from beverage raw materials and selling them in cups. The present invention relates to a beverage extracting device capable of producing a stable beverage.

[0002]

2. Description of the Related Art A conventional beverage extracting apparatus includes an extractor for extracting a beverage from a mixture of powdered raw material (coffee powder) and hot water supplied from above, a powdered raw material container for supplying the powdered raw material to the extractor, A hot water tank for supplying hot water to the extractor and a control unit for controlling the extractor and the hot water tank are provided. The hot water tank heats tap water supplied through a tap water solenoid valve to make hot water for extraction at a predetermined temperature (for example, 97 ° C.), and a temperature for detecting the temperature of hot water in the hot water tank. It has a sensor, a float for detecting the amount of hot water in the hot water tank, and a hot water solenoid valve for supplying hot water in the hot water tank to the extractor.

[0003] In the beverage brewing apparatus configured as described above, when the sales signal is output to the control unit, the control unit opens the hot water electromagnetic valve to supply a fixed amount of hot water from the hot water tank to the brewing machine and to extract the hot water. The machine is controlled to extract the coffee beverage.
On the other hand, when hot water is supplied to the extractor, the amount of hot water in the hot water tank is reduced. Therefore, the control unit opens the tap water solenoid valve based on the detection of the amount of hot water in the float and replenishes tap water. When tap water is supplied to the hot water tank, the temperature of the hot water in the hot water tank decreases. Therefore, the control unit heats the hot water in the hot water tank by the heater based on the detection of the hot water temperature by the temperature sensor. Since the temperature of the hot water in the hot water tank is kept constant, the time for extracting the coffee beverage can be shortened, and the coffee beverage can be provided without waiting for the customer much. In addition, if the supply of tap water to the hot water tank increases continuously and the hot water temperature drops to a predetermined temperature (for example, less than 85 ° C.), the sales are stopped. Thereby, since extraction is always performed at a temperature suitable for extraction, a high-quality coffee beverage can be provided.

[0004]

However, according to the conventional beverage brewing apparatus, the temperature of hot water used for brewing is at least 85.
Because of the temperature difference between the temperature and the maximum of 97 ° C., the degree of elution of coffee components such as taste, astringency, bitterness, and sourness is different, and there is a problem that the concentration of the coffee beverage is not constant.

[0005] Accordingly, an object of the present invention is to provide a beverage extraction device capable of producing a beverage having a stable concentration.

[0006]

In order to achieve the above object, the present invention provides a beverage extracting apparatus for extracting a beverage from a mixture of a beverage raw material and hot water supplied into an extraction chamber under predetermined extraction conditions. A raw material tank for supplying a raw material to the extraction chamber, a hot water tank for supplying the hot water to the extraction chamber,
There is provided a beverage extracting apparatus, comprising: a temperature detecting means for detecting a temperature of the hot water; and a control means for setting the brewing condition based on the temperature detected by the temperature detecting means.
