[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extraction device having a function of effectively extracting a mixed solution of an extraction device used for a cup-type vending machine or the like.

[0002]

2. Description of the Related Art In recent years, as an extraction apparatus of this type, an apparatus which mixes coffee powder raw materials obtained by grinding coffee beans with hot water, inclines the mixture, and extracts the extract is well known.
As described above, it is shown that in order to dissolve a fixed amount of powdered raw material with a fixed amount of boiling water, a good effect cannot be obtained in a stationary state in which hot water and the powdered raw material are simply mixed, and stirring is required.

A structure of a conventional extraction device characterized by using compressed air to stir a mixture of hot water and a powdered raw material is disclosed in Japanese Utility Model Laid-Open Publication No. 64-31480.

Hereinafter, the above-mentioned conventional extracting device will be described with reference to the drawings. FIG. 10 is a block diagram showing a configuration of a conventional extraction device. In FIG. 10, reference numeral 1 denotes an extraction chamber for stirring hot water and powdered raw materials to form a mixed liquid. Reference numeral 2 denotes a shooter, which is a passage for introducing hot water and powdered raw materials into the extraction chamber 1. 3 is an extraction chamber valve,
The shooter 2 and the extraction chamber 1 are opened and closed. Reference numeral 4 denotes an air pump for introducing compressed air for stirring a mixture of hot water and powdered raw materials. Reference numeral 4a denotes a driving motor, which is a motor for driving the air pump 4. Reference numeral 5 denotes a filter for filtering the mixture. Reference numeral 6 denotes a filter pedestal, on which the filter 5 is placed and the extraction chamber 1 is sealed. Arrows indicate the direction of travel of the air.

[0005] The operation of the extraction apparatus configured as described above will be described below. First, the extraction chamber valve 3 is lowered in a state where the extraction chamber 1 and the filter cradle 6 are in close contact with each other through a filter 5, and hot water and powder raw material are put into the extraction chamber 1 from the shooter 5. By electrically operating the drive motor 4a of the air pump 4, the compressed air is introduced from the outside and agitated, and the extraction chamber 1 is closed by raising the extraction chamber valve 3, so that the mixed liquid is stirred. Pressurized extraction with the same compressed air.

[0006]

However, by stirring a mixture of boiling water and powdered raw material, a powder extract and aroma are extracted from the powdered raw material into boiling water.
In the above conventional configuration, since the drive motor of the air pump for stirring the mixed liquid is controlled by the rated number of rotations, it is only stirred with a fixed compressed air, so that the beverage is continuously sold. In the case of a powdery raw material having a small contact area with hot water at the time of lowering the temperature of the hot water or stirring, and having a coarse particle size, there is a disadvantage that the powder extract and aroma are not sufficiently extracted from the powdery raw material into the hot water.

The present invention solves the above-mentioned conventional problems and provides an extraction apparatus in which stirring and extraction are effectively performed.

[0008]

SUMMARY OF THE INVENTION To achieve this object, the present invention is to control the rotation speed of a drive motor of an air pump at the time of stirring and pressurized extraction to fluctuate the amount of compressed air to thereby improve the stirring and extraction effects. By improving the temperature, it is possible to sufficiently agitate a wide variety of raw materials, such as a case where the temperature of the hot water is lowered or a powder raw material having a coarse particle size is used.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to an extraction chamber in which boiling water and a powdered raw material are stirred to form a mixed solution,
A shooter, which is a passage for charging, an extraction chamber valve for opening and closing the shooter and the extraction chamber, and an air pump for stirring a mixed solution of hot water and powdered raw material with compressed air,
A drive motor that drives the air pump, a drive motor rotation speed control unit that varies the amount of compressed air of the air pump by changing the rotation speed of the drive motor, and variably setting the rotation speed of the drive motor; A main control unit for controlling the drive motor rotation speed control means, a filter for filtering the mixture, and a filter pedestal for mounting the filter and sealing the extraction chamber are provided.

When the temperature of the hot water drops when the beverage is sold continuously, the temperature of the hot water is detected by the hot water temperature detecting means, and the rotation speed of the drive motor of the air pump is controlled by the drive motor speed control. By increasing the amount of compressed air, the agitation of the mixed liquid is improved even when the temperature of the hot water is lowered, and the powder extract and the aroma can be sufficiently extracted from the powder raw material into the hot water. Further, even in the case of a powdery raw material having a coarse particle size, sufficient stirring can be achieved by the same operation as that for lowering the hot water temperature by variably setting the rotation speed of the drive motor using the main control unit. However, when there is a problem of insufficient filter strength at the time of extraction, the extraction can be performed by reducing the rotation speed of the drive motor by the motor drive rotation speed control means to reduce the amount of compressed air. As mentioned above,
By electrically controlling the drive motor of the air pump by controlling the rotation speed of the drive motor and varying the amount of compressed air at the time of stirring and extraction, it is possible to supply a beverage from which the powder extract has been sufficiently extracted.

Then, a suction tube is connected between the upper portion of the hot water tank and the air pump suction port, and the high-temperature steam in the hot water tank is sucked and sent to the extraction chamber to be stirred, thereby preventing the temperature of the mixture from dropping. The stirring effect can be improved. However, since there is a drop in the temperature of the high-temperature steam between the upper part of the hot water tank and the inlet of the air pump, it is necessary to minimize the length of the suction tube and take measures to keep it warm.

At the time of stirring, only the shooter opening at the top of the extraction chamber is closed by raising the convex extraction chamber valve and closing the air valve. By doing so, the vapor accompanying the scent produced when the mixed solution is produced is circulated. At the time of pressurized extraction, the shooter opening and the circulation opening at the top of the extraction chamber are closed, and an air valve is opened to perform pressure extraction. This makes it possible to supply a high-quality beverage without escaping a fragrance that is very important for a beverage (especially a coffee beverage) at the time of stirring, and to improve the extraction effect.

Extracts and scents can be sufficiently extracted. Further, even in the case of a powdery material having a coarse particle size, sufficient stirring can be achieved by the same operation as that for lowering the hot water temperature by variably setting the rotation speed of the stirring body drive motor using the main control unit.

In addition, hot water and air are injected by a pump by switching the hot water valve and the air valve by controlling the rotation speed regardless of the temperature of the hot water and the particle size of the powdery raw material. Since there is a difference between the pressure and the air pressure for preventing the remaining liquid, the pressure was adjusted by a flow rate regulator for adjusting the flow rates of the hot water and the air between the hot water valve and the pipe configuration of the pump outlet.

When the temperature of the hot water drops when the beverage is sold continuously, the temperature of the hot water is detected by the hot water temperature detecting means, and the rotation speed of the drive motor of the air pump is controlled by the drive motor speed control. By lowering the amount of hot water poured into the beverage package and increasing the contact time between the powder raw material and the hot water, the stirring property of the mixed liquid is improved even if the hot water temperature is lowered, The hot water can sufficiently extract the powder extract and the aroma. Further, even in the case of a powdery raw material having a coarse particle size, sufficient stirring can be achieved by the same operation as that for lowering the hot water temperature by variably setting the rotation speed of the drive motor using the main control unit. However, at the time of air injection for preventing remaining beverage liquid, the air can be extracted by increasing the rotation speed of the drive motor by the motor drive rotation speed control means to increase the amount of compressed air. As described above, a beverage from which a powder extract has been sufficiently extracted can be supplied by varying the amount of hot water extraction and air extraction at the time of hot water extraction and air extraction by electrically controlling the drive motor of the air pump by controlling the drive motor speed.

The pressure was adjusted by the flow regulator, but the drive motor of the air pump was electrically changed by the drive motor rotation speed control means, so that the flow regulator became unnecessary and the mechanism was simplified. be able to.

As described above, according to the present invention, when the temperature of the hot water drops when the beverage is sold continuously, the low temperature of the hot water is detected by the hot water detecting means, and the driving motor speed is controlled. By increasing the number of rotations of the drive motor of the air pump and increasing the amount of compressed air, even if the temperature of the hot water is low, the agitation of the mixed liquid is improved, and the powder extract and scent can be sufficiently converted from the powder raw material to the hot water Can be extracted. Further, even in the case of a powdery raw material having a coarse particle size, sufficient stirring can be achieved by the same operation as that for lowering the hot water temperature by variably setting the rotation speed of the drive motor using the main control unit. However,
When there is a problem of insufficient filter strength at the time of extraction, the extraction can be performed by lowering the rotation speed of the drive motor by the motor drive rotation speed control means to reduce the amount of compressed air. As described above, a beverage from which a powder extract has been sufficiently extracted can be supplied by varying the amount of compressed air during stirring and extraction by electrically controlling the drive motor of the air pump by controlling the rotation speed of the drive motor.

Further, conventionally, air in a vending machine warehouse at a temperature lower than the temperature of the mixed liquid is sucked by an air pump, sent to an extraction chamber and agitated and extracted under pressure. Due to the decrease in temperature, the extraction of the powder extract from the powdered raw material into hot water was insufficient, and there was a problem that the stirring effect and the temperature of the beverage were lowered, but the upper part in the hot water tank and the air pump suction port were By connecting a suction tube, sucking high-temperature steam in the hot water tank, sending it to the extraction chamber and stirring the mixture, it is possible to prevent a decrease in the temperature of the mixed liquid and improve the stirring effect.

Further, the circulation opening at the upper part of the extraction chamber is connected to the air pump suction port. At the time of stirring, only the shooter opening at the upper part of the extraction chamber is raised and closed by raising the convex extraction chamber valve. By closing the
Circulate the vapor with the scent that comes out of the mixture. At the time of pressurized extraction, the shooter opening and the circulation opening at the top of the extraction chamber are closed, and an air valve is opened to perform pressure extraction. This makes it possible to supply a high-quality beverage without escaping a fragrance that is very important for a beverage (especially a coffee beverage) at the time of stirring, and to improve the extraction effect.

Further, a stirrer is connected to the lower part of the piston, and when the temperature of the hot water drops when the beverage is sold continuously, the lowering of the hot water is detected by the hot water temperature detecting means, and the stirrer is driven. By increasing the number of rotations of the stirrer drive motor of the stirrer by controlling the motor rotation speed and increasing the agitation of the mixture, the agitation of the mixture is improved even if the temperature of the hot water is lowered, and the hot water Powder extract and aroma can be sufficiently extracted. Further, even in the case of a powdery material having a coarse particle size, sufficient stirring can be achieved by the same operation as that for lowering the hot water temperature by variably setting the rotation speed of the stirring body drive motor using the main control unit. As described above, a beverage from which a powder extract has been sufficiently extracted can be supplied by varying the rotation speed during stirring by electrically controlling the rotation speed of the stirring body drive motor of the stirring body drive motor of the stirring body.

Further, when the temperature of the hot water drops when the beverage is sold continuously, the lowering of the hot water temperature is detected by the hot water temperature detecting means, and the rotational speed of the drive motor of the pump is controlled by controlling the rotational speed of the drive motor. By lowering the amount of hot water poured into the beverage package and increasing the contact time between the powdered raw material and the hot water, the stirring property of the mixed liquid is improved even when the hot water temperature is lowered, Can extract the powder extract and the scent sufficiently into boiling water. Further, even in the case of a powdery raw material having a coarse particle size, sufficient stirring can be achieved by the same operation as that for lowering the hot water temperature by variably setting the rotation speed of the drive motor using the main control unit. However, at the time of air injection for preventing remaining beverage liquid, the air can be extracted by increasing the rotation speed of the drive motor by the motor drive rotation speed control means to increase the amount of compressed air. As described above, the beverage in which the powder extract has been sufficiently extracted can be supplied by varying the amount of hot water extraction and air extraction at the time of hot water extraction and air extraction by electrically controlling the drive motor of the pump by controlling the drive motor speed. Also,
Hot water and air are injected by a pump by switching the hot water valve and air valve by controlling the number of rotations regardless of the temperature of the hot water and the particle size of the powder raw material. Because there is a difference between the air pressure for preventing the remaining beverage liquid, the pressure was adjusted by a flow regulator that adjusts the flow rate of hot water and air between the hot water valve and the pipe configuration of the pump outlet. By electrically varying the rotation speed of the drive motor by the drive motor rotation speed control means, a flow controller is not required, and the mechanism can be simplified.

Further, when the temperature of the hot water drops when the beverage is sold continuously, the temperature of the hot water is detected by the hot water detecting means, and the rotation of the drive motor of the air pump is controlled by controlling the drive motor speed. By lowering the number, reducing the amount of hot water injected into the beverage package and increasing the contact time between the powder raw material and the hot water, thereby improving the agitation of the mixed liquid even when the hot water temperature is low, The powder extract and the aroma can be sufficiently extracted from the raw material into boiling water. Further, even in the case of a powdery raw material having a coarse particle size, sufficient stirring can be achieved by the same operation as that for lowering the hot water temperature by variably setting the rotation speed of the drive motor using the main control unit. However, at the time of air injection for preventing remaining beverage liquid, the air can be extracted by increasing the rotation speed of the drive motor by the motor drive rotation speed control means to increase the amount of compressed air. As described above, a beverage from which a powder extract has been sufficiently extracted can be supplied by varying the amount of hot water extraction and air extraction at the time of hot water extraction and air extraction by electrically controlling the drive motor of the air pump by controlling the drive motor speed. In addition, hot water and air are injected by an air pump by switching the hot water valve and the air valve by controlling the rotation speed regardless of the temperature of the hot water and the particle size of the powdery raw material. Because there is a difference between the extraction pressure and the air pressure for preventing the remaining beverage liquid, the pressure is adjusted by a flow regulator that adjusts the flow rate of hot water and air between the hot water valve and the pipeline configuration from the sub tank outlet and to the air pump inlet side. Although the adjustment has been performed, the drive motor of the air pump is electrically varied in rotation speed by the drive motor rotation speed control means, so that a flow controller is not required and the mechanism can be simplified.
