Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for extracting beverages such as drained coffee, barley tea, and cold tea (green tea).
[0002]
[Prior art]
Conventional beverage extraction methods, for example, coffee extraction methods, use hot water such as “drip”, “siphon”, “espresso” and others that use room temperature water called “watering”. . This “watering out” extraction method is called a water drip or Dutch method.
The coffee put by this “watering out” is popular among coffee lovers because it does not escape the scent and can bring out good sweetness and soft bitterness.
A conventional extraction device for extracting coffee by such “watering” (hereinafter simply referred to as “watering coffee”) includes a glass water storage tank and a glass extraction tank disposed below the water storage tank. And a container for receiving the extraction liquid flowing out from the outlet of the extraction tank. In order to extract drained coffee with this extraction device, coffee powder is put in the extraction tank, and a very small amount of water is extracted in the extraction tank by adjusting the flow rate adjustment valve provided at the outlet of the water storage tank. The extract is dripped intermittently, and the extract liquid dripped little by little from the extraction tank, that is, the drained coffee is stored in the container.
[0003]
There are two methods for extracting barley tea: a method in which roasted barley is boiled in hot water, and a method in which the barley tea is extracted by simply immersing it in water without heating.
[0004]
[Problems to be solved by the invention]
By the way, extraction of watered coffee has an advantage that it can produce a fragrance and taste that cannot be produced by other extractions, but has a problem that extraction requires a long time (for example, 8 to 24 hours). For this reason, in the coffee shop, it must be extracted before opening the shop, preparation for opening the shop is troublesome, and the quality control of the watered coffee is complicated. Also, since the time required for extraction is too long, it was impossible to extract after receiving the customer's order. Therefore, even if it is known that the flavor of the watered coffee is excellent and meets the customer's needs, it is extremely difficult to adopt it as a business item.
[0005]
In addition, in the case of cold beverages typified by barley tea, if you respect the incense, it will be boiled and extracted with hot water, and after cooling it must be cooled naturally in the refrigerator after cooling naturally, which takes time and effort. . Similarly, since cold tea uses hot water during extraction, it was necessary to cool it separately after extraction.
[0006]
Then, an object of this invention is to provide the drink extraction apparatus which can extract drinks, such as draining coffee, easily in a short time.
[0007]
[Means for Solving the Problems]

The opening of the extraction bag body is sealed by the sealing mechanism in a state where the extraction bag body containing the extraction raw material and water is placed and accommodated on the extraction bag body support portion in the decompression container, and the inside of the decompression container is decompressed. Thus, the beverage extraction apparatus is characterized in that the air in the extraction bag is extracted while being deaerated from the ventilation portion.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, taking extraction of drained coffee as an example.
1 is a perspective view seen from the front side of the operation of the drained coffee extraction device 1 with the lid open, FIG. 2 is a cross-sectional view of the extraction device 1 with the lid closed, and FIG. 4 is a perspective view of the extraction bag body 3. FIG.
[0009]
As shown in FIG. 1 and FIG. 2, the drained coffee extraction device 1 is provided with a decompression container 2 inclined on the top of a housing 4, and an opening 3 a of an extraction bag 3 is provided inside the decompression container 2. A vacuum pump 5, a power supply device, and the like are provided in the casing 4 below the decompression container 2, and the operation panel 6 is provided on the side surface of the casing 4 located on the inclined upper end side of the decompression container 2. A control device 7 is provided on the back side of the operation panel 6. That is, the inside of the decompression container 2 in the present invention is inclined so that the operation front side facing the operator is high and the opposite side is low.
[0010]
The decompression vessel 2 is composed of a metal box-like decompression vessel body 2a having an inclined bottom and an upper surface opened, and a lid 2b that seals the upper surface opening of the decompression vessel body 2a, and is provided on the lower side. The lid 2b is supported by the hinge mechanism 9 so as to be openable and closable with respect to the decompression vessel body 2a, and the lid 2b can be locked in a closed state by the locking mechanism 10 provided on the high side, and the window of the lid 2b closed with a transparent plate material 11 so that the inside of the decompression vessel main body 2a can be confirmed.
[0011]
Further, the other end of the suction-side flow path having one end connected to the suction port of the vacuum pump 5 is connected to the exhaust port 12 opened in the bottom surface portion of the decompression container body 2a. Therefore, when the vacuum pump 5 is operated in a state where the top surface opening of the decompression container body 2a is covered with the lid 2b and the decompression container 2 is closed, the air in the decompression chamber 13 surrounded by the decompression container body 2a and the lid body 2b. Can be discharged to the outside through the exhaust port 12, whereby the pressure in the decompression chamber 13 can be reduced to near vacuum.
In addition, the sealing material 14 is provided on the lower surface of the lid 2b corresponding to the opening edge of the decompression container body 2a, and the airtightness of the decompression chamber 13 is ensured.
[0012]
In the decompression container body 2a, as shown in FIG. 3, the opening 3a of the extraction bag 3 containing the coffee beans and water as the extraction raw material is positioned on the inclined upper side of the bottom so that the opening 3a is located in the sealing mechanism. A bag body stopper 15 is provided on the inclined lower side of the sealing mechanism. The bag body stopper 15 is a stopper that supports the bottom 3b side (the side opposite to the opening 3a) of the extraction bag body 3 and positions the opening 3a in the sealing mechanism. It arrange | positions in the orthogonal direction and can adjust a position according to the size of the extraction bag body 3. FIG. Specifically, it is set by fitting both ends of the plate-shaped bag body stopper 15 into either of the plurality of grooves 16 formed in the vertical direction on both side surfaces of the inclined decompression vessel body 2a. The positional relationship between the opening 3a of the extraction bag 3 and the sealing mechanism can be adjusted by the position of the groove 16 to be joined. Therefore, by adjusting the position of the bag body stopper 15, even the extraction bag body 3 having a different length from the opening 3a to the bottom 3b can be used without any trouble.
[0013]
In this embodiment, the position-adjustable bag body stopper 15 and the bottom surface portion of the decompression container body 2a inclined at a certain angle constitute the main part of the extraction bag body support portion in the present invention. The body support portion can support the opening 3 a of the extraction bag body 3 accommodated in the decompression container 2 at a position higher than the bottom side of the extraction bag body 3. Therefore, when the extraction bag 3 having a large volume (the size from the opening 3a to the bottom 3b is extended to increase the volume in the longitudinal direction) is accommodated in the decompression container body 2a, the position of the bag stopper 15 is set. By adjusting to the inclined lower side, it can be accommodated in the decompression vessel 2 without changing the position of the opening 3a of the extraction bag support.
[0014]
Moreover, since the extraction bag body support part supports the opening 3a of the accommodated extraction bag body 3 at a position higher than the bottom side of the extraction bag body 3, the contents contained in the extraction bag body 3 are stored in the decompression container 2 Never spill inside. Furthermore, since the decompression container body 2a is formed to have substantially the same depth and the upper surface opening edge of the housing is inclined downward from the operation front side, when the decompression container body 2a is attached to the casing 4, the decompression container 2 The bottom surface portion is inclined in such a direction that the operation front side is high and the opposite side is low. Therefore, the contents contained in the extraction bag 3 accommodated in the decompression container 2 are not spilled into the decompression container 2 even from this configuration.
[0015]
A sealing mechanism is provided near the inclined upper end of the decompression chamber 13 of the decompression container 2 having the above-described configuration. This sealing mechanism is provided on the decompression vessel body 2a side so as to be movable up and down, and is fixed to the lower heater block 20 that is long in the width direction of the decompression chamber 13 and the lower surface side of the lid 2b. A long upper heater block 21 is disposed at a position facing the upper heater block 21, and heat rays are attached to the ends of the opposed heater blocks 20, 21. It is comprised so that it may press-contact to the block 21 side. Since the lower heater block 20 is a block-like member that stands upward from the bottom surface of the decompression container body 2a, when the opening 3a side of the extraction bag body 3 is placed, the opening 3a is used as the extraction bag body. 3 is supported at a position that is surely higher than the bottom side. Therefore, in this embodiment, the lower heater block 20 also functions as a part of the extraction bag body support portion.
[0016]
In the pressure cylinder 22, the piston 23 is urged downward by a return spring 24, and the piston 23 divides the inside of the cylinder into an upper first chamber and a lower second chamber, and the second chamber has an opening hole 25. The first chamber is connected to the suction side flow path of the vacuum pump 5 via the branch flow path.
[0017]
Therefore, if the vacuum pump 5 is operated in a state where the electromagnetic valve 26 in the middle of the branch flow path is operated to connect the suction-side flow path of the vacuum pump 5 and the first chamber of the cylinder, the first chamber is negatively pressurized. When the piston 23 rises against the bias of the return spring 24, the lower heater block 20 rises and comes into pressure contact with the upper heater block 21, and when heated by heat rays in this state, the extraction bag body sandwiched therebetween 3 can be sealed by thermocompression bonding (sealing by heat sealing). When the electromagnetic valve 26 is operated to communicate the first chamber with the outside air, the piston 23 is lowered by the biasing force of the return spring 24, whereby the lower heater block 20 returns to the original position and the extraction bag 3 All the sealing operations of the opening 3a are completed.
[0018]
As described above, the sealing mechanism shown in the drawing is composed of the lower heater block 20, the upper heater block 21, and the pressure cylinder 22. The lower heater block 20 serves as the lower sealing portion, and the upper heater block 21 serves as the upper sealing portion. Function as.
[0019]
As shown in FIG. 4, the extraction bag body 3 into which coffee beans and water are placed is made of a vertically long heat-sealable transparent resin, one end in the longitudinal direction is sealed in advance to become the bottom side, and the other end is coffee beans. And an opening 3a for water. Further, a breathable ventilation portion 30 that prevents the passage of water and allows the passage of air is formed in a belt shape along the longitudinal direction of the extraction bag body 3 at substantially the center of either one of the front and back sides. The ventilation portion 30 in the present embodiment is a sheet shape in which a paper fiber is impregnated with a resin, and can be heat-sealed with other transparent resin portions constituting the extraction bag body 3. The extraction bag 3 may be a bag having any configuration as long as it has a ventilation portion 30 that prevents the passage of water and allows the passage of air, and the position of the ventilation portion 30 can be appropriately set. it can.
[0020]
The control device 7 includes a one-chip microcomputer incorporating ROM, RAM, CPU, and the like, an input interface and an output interface, and the like. Various operation switches provided on the panel 6 are controlled. In the ROM, a control program for extracting coffee components from the coffee beans and water put in the extraction bag 3 is stored. The control device 7 is not limited to one using a microcomputer, and may be configured by a hard logic circuit.
[0021]
Next, an extraction method for extracting drained coffee using the drained coffee extraction apparatus 1 will be described. Note that the graph shown in FIG. 5 shows the reduced pressure value (dotted line) in the reduced pressure container 2 decompressed by the vacuum pump 5 and the reduced pressure value (solid line) in the extraction bag body 3 accommodated in the reduced pressure container 2 over time. It is a representation.
[0022]
First, coffee beans (ground coffee beans) and water are put into the extraction bag 3 from the opening 3a of the extraction bag 3, and the lid 2b of the decompression container 2 is opened. As shown in FIG. 3, the opening 3 a is placed on the lower heater block 20 while being laid on the bottom of the decompression vessel main body 2 a while supporting the bottom 3 b of the bag 3 with the bag stopper 15. Even if the opening 3a of the extraction bag 3 is open, the extraction bag support supports the opening 3a of the extraction bag 3 at a position higher than the bottom side of the extraction bag 3, so that water spills. Never leave.
[0023]
Next, as shown in FIG. 7, the lid body 2 b is closed and the lid body 2 b is locked by the lock mechanism 10. Then, by performing an input operation on a start switch provided on the operation panel 6, the extraction control of the drained coffee is started.
[0024]
When the control device 7 detects the input of the start switch, the lid 2b is detected based on a signal from a lid 2b open / close detection sensor (not shown) that detects the open / closed state of the lid 2b provided in the decompression vessel 2. Whether the cover 2b is closed or not is detected, the start switch input is validated. On the other hand, when the lid 2b is not closed, the start switch input is invalidated, such as a lamp or buzzer. Attention is drawn to safety.
[0025]
When the input of the start switch is detected, as a preliminary decompression process, the electromagnetic valve 26 is operated to connect the decompression container 2 and the suction port of the vacuum pump 5 through the suction side flow path, and the vacuum pump 5 is operated for 2 to 3 seconds. Activate and perform pre-depressurization. When this preliminary depressurization is performed, the depressurized container 2 is in a depressurized state of, for example, 600 mmHg, and the lid 2b of the depressurized container 2 is pressed against the depressurized container main body 2a by the atmospheric pressure to be surely sealed. In addition, since the opening 3 a of the extraction bag body 3 remains open, the air in the extraction bag body 3 is also discharged and is in the same decompressed state as in the decompression container 2.
[0026]
Next, as the extraction bag body opening sealing step, the electromagnetic valve 26 is operated under the pre-reduced pressure state to shut off the communication between the decompression chamber 13 and the suction side of the vacuum pump 5, and the suction of the vacuum pump 5 The vacuum pump 5 is operated by connecting the side and the first chamber of the cylinder. Then, as shown in FIG. 8, the lower heater block 20 constituting the sealing mechanism is pressed against the upper heater block 21 side by driving the pressure cylinder 22. The upper heater block 21 can reliably receive the upward force from the lower heater block 20 because the lid body 2b is pressed downward by the atmospheric pressure through the preliminary decompression step. In this state, power is supplied to the heat wires of both heater blocks 20 and 21 for about 2 seconds, and the opening 3a of the extraction bag 3 is thermally welded by heating at this time. And if heat welding is complete | finished, the electric power supply to the heat wire of both the heater blocks 20 and 21 will be stopped in a press-contact state, and it will cool for 4 to 6 seconds. When the cooling is completed, the electromagnetic valve 26 is operated to open the first chamber to the atmosphere, thereby returning the lower heater block 20 to the original position. This completes the extraction bag body opening sealing step.
[0027]
Next, as an extraction process for extracting the drained coffee, the electromagnetic valve 26 is operated to connect the decompression container 2 and the suction port of the vacuum pump 5, and the inside of the decompression container 2 is again operated by the operation of the vacuum pump 5. When the pressure is reduced and the pressure is reduced for about 120 to 180 seconds, the inside of the pressure reduction container 2 is reduced to near 0 mmHg.
[0028]
When the pressure in the decompression chamber 13 is reduced in this way, the air in the extraction bag 3 is gradually degassed through the ventilation portion 30 in the sealed extraction bag 3 and the pressure is reduced to near 0 mmHg. . During this decompression process, a phenomenon similar to boiling occurs in the extraction bag 3 at room temperature (low temperature), the air inside the coffee beans, which is a porous material, escapes, and water penetrates into the fine voids of the coffee beans, As a result, the coffee components are extracted with water to produce drained coffee. Moreover, since the ventilation part 30 gives resistance to the air flow and delays the decrease in the atmospheric pressure in the extraction bag body 3, it can be extracted over the same time as heating or boiling of hot water, and the quality of the extraction Can be improved. In other words, the extraction action using heat can be performed at a low temperature by adding the condition of reduced pressure.
[0029]
In addition, in the conventional method of adding watered coffee such as a water drip, it was difficult to remove the coffee by adsorbing the miscellaneous taste of the coffee like drip or siphon performed with hot water, but in the above extraction process When the air in the extraction bag 3 is degassed from the ventilation portion 30, bubbles are generated by the expansion of the air in the fine gaps of the coffee beans, and the miscellaneous taste of the coffee is adsorbed to the bubbles. be able to. Therefore, it is possible to make a drained coffee that does not have a nuisance even if it is extracted at room temperature. Moreover, since the miscellaneous taste contained in the coffee bean skin is difficult to be extracted at room temperature, it is less than in the case of drip or siphon using hot water.
[0030]
When the extraction process is completed, the electromagnetic valve 26 is operated to open the decompression container 2 to the atmosphere for a predetermined time (6 to 8 seconds). And the completion | finish process which alert | reports that extraction of the draining coffee was complete | finished with the lamp | ramp or the buzzer after predetermined time progress is performed. When this end step is completed, the inside of the decompression chamber 13 is returned to the atmospheric pressure, so that the lid 2b can be opened, the lock mechanism 10 is released, the lid 2b is opened, and the extraction bag body from which the coffee component has been extracted is extracted. 3 is taken out (FIG. 9).
[0031]
Then, when the extracted extraction bag 3 is opened and filtered with a filter or the like to remove the coffee beans, drained coffee is completed. In order to enjoy the flavor, it is desirable that the watered coffee produced in this way be drunk as iced coffee by pouring it into a glass containing ice as it is or by pouring it into a glass containing ice after cooling. However, depending on taste, it may be warmed and drained hot coffee.
[0032]
As described above, the extraction of the drained coffee by the drained coffee extraction apparatus 1 of the present invention takes the required time even if the preliminary decompression step, the extraction bag body opening portion sealing step, the extraction step, and the end step are combined. Can be performed in an extremely short time of 134 to 199 seconds. Also, by simply putting a predetermined amount of coffee beans and water in the extraction bag 3 and setting the extraction bag 3 in the water extraction coffee extraction device 1, pressing the start switch makes it possible to easily make water discharge coffee. . Therefore, it is possible to add watered coffee that maintains a certain quality even without specialized knowledge.
[0033]
Moreover, in this embodiment, after performing a preliminary | backup pressure reduction process, the opening part 3a of the extraction bag body 3 is sealed, and after that, the inside of the pressure reduction container 2 is pressure-reduced again, and an extraction process is performed, Therefore Rupture can be prevented, and a decrease in the atmospheric pressure in the extraction bag 3 can be slightly delayed from the decrease in the atmospheric pressure in the outside (the decompression chamber 13) to extract a flavored water-deposited coffee. That is, the pressure reduction efficiency in the initial stage of the decompression in the decompression vessel 2 is good, and the inside of the extraction bag 3 is preliminarily decompressed by the preliminary decompression and then sealed rather than abruptly decompressing in the state of the atmospheric pressure without the preliminary decompression. When the pressure is reduced, the extraction bag body 3 can be prevented from expanding rapidly, thereby reducing the rupture trouble. Further, since the extraction step is performed after the preliminary decompression, it is possible to prevent moisture from being discharged from the ventilation portion 30 of the extraction bag 3 due to the rapid decompression seen at the beginning of the decompression. For this reason, the inside of the decompression container 2 is not soiled. Furthermore, if leakage of moisture can be prevented, troubles such as occurrence of moisture flowing into the oil of the vacuum pump 5 can be prevented in advance.
[0034]
In order to omit the coffee bean removal operation using a filter or the like, the ground coffee beans may be extracted by placing them in the extraction bag 3 in a state of being included in a filter that allows passage of water and air. . For example, coffee beans may be put in a non-woven bag used for tea bags, for example, and this may be put together with water in the extraction bag 3 and extracted by the above operation. In this way, the coffee beans after extraction remain in the non-woven bag, so that it is not necessary to perform the filtration step as in the above embodiment, and the drained coffee can be added more easily.
[0035]
Moreover, although the said embodiment demonstrated and demonstrated the water | moisture-content coffee, the present invention is not limited to this. In other words, the type of beverage to be extracted is simply an appropriate selection of the type of raw material to be extracted. For example, roasted barley can be used when extracting barley tea, and green tea can be used when cooling tea. In addition, the present invention has a more remarkable effect when used in a coffee shop, a restaurant, a restaurant, and the like.
[0036]
In short, as an extraction method, an extraction bag body opening portion that seals the opening portion of the extraction bag body by putting the extraction raw material and water into the extraction bag body having a ventilation portion that prevents the passage of water and allows the passage of air. Extraction is performed through a sealing step, and then an extraction step in which the air in the extraction bag is degassed and extracted by reducing the pressure in the pressure reduction container while the extraction bag is housed in the pressure reduction container. To do.
[0037]
In addition, the extraction method includes the extraction raw material and water in an extraction bag body having a ventilation portion that prevents the passage of water and allows the passage of air, and the inside of the decompression container with the opening portion of the extraction bag body opened.

In this case, after performing pre-depressurization, the opening of the extraction bag is sealed, and air in the extraction bag is degassed from the vent of the sealed extraction bag, for example, coffee ingredients Since the components are extracted, it is possible to reduce troubles such as the sealed extraction bag body suddenly expanding and rupturing, and water being discharged from the ventilation portion. Therefore, there is no possibility that the inside of the decompression container is soiled.
[0038]
