For example, a coffee maker extracts an extract from ground coffee beans, but it is doubtful whether all umami components are extracted. <00OO028>The present inventor has conducted research starting from this naive question. The present invention aims to provide an extract extraction device that can more effectively extract active ingredients and umami components.

Means for Solving the Problems

[0005] The inventor, driven by a strong desire to create better-tasting coffee, conducted extensive research. As a result, it was discovered that delicious coffee can be brewed using the following extract extraction device. In other words, an embodiment for solving the above-mentioned problems is an extract extraction device having a plurality of magnets and a conductive member, wherein the plurality of magnets have portions of different polarities close together or in contact, the conductive member is made up of a plurality of conductors with different electrical resistances, and the conductive member is wrapped around the magnets.

[0006] The extract extraction device according to this embodiment is installed near the extract-containing member, and current is applied to the conductive member.

[0011] The extract-containing material may be organic or inorganic. For example, the extract-containing material may be a beverage ingredient such as coffee beans, black tea leaves, green tea leaves, or barley (barley tea). It may also be a plant-derived ingredient in traditional Chinese medicines or supplements, such as Houttuynia cordata, kudzu, Epimedium, peony, or corn silk. It may also be an animal-derived ingredient in traditional Chinese medicines or supplements, such as earthworms, newts, or clams. Furthermore, it may be a mineral-derived ingredient in beverages or supplements. The current supplied to the conductive material should preferably be direct current, but alternating current is also acceptable.

[0012] The invention of a beverage manufacturing method is characterized by comprising the steps of immersing an extract-containing member in a liquid, arranging one of the above-described extract extraction devices nearby, and applying electricity to the conductive member of the extract extraction device.

Modes for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described. The invention described in the claims is not limited to the embodiments described below. The extractor device 1 of the present embodiment has two bar magnets 2 and 3 and a conductor member 5 as shown in FIG. 1, and the conductor member 5 is wound around the two bar magnets 2 and 3.

[0019] As shown in FIG. 3, the conductor member 5 is formed by twisting and combining three metal wires 10, 11, and 12. The metal wire 10 is a copper wire, the metal wire 11 is an aluminum wire, and the metal wire 12 is an iron wire. That is, all of the metal wires 10, 11, and 12 are electrically conductive. The conductor member 5 is formed by twisting three metal wires 10, 11, and 12 together. The metal wires 10, 11, and 12 are made of different materials and naturally have different electrical resistances. That is, the metal wire 10 is a copper wire, and the volume resistivity at 0 degrees Celsius is 1.55 μΩcm (micro-ohm-centimeter). The metal wire 11 is an aluminum wire, and the volume resistivity at 0 degrees Celsius is 2.50 μΩcm (micro-ohm-centimeter). The metal wire 12 is an iron wire, and the volume resistivity at room temperature is 10 to 20 μΩcm (micro-ohm-centimeter).

[0020] The bar magnets 2 and 3 are entirely straight bar-shaped. One end side of the bar magnets 2 and 3 has a N pole, and the other end side has a S pole. In the present embodiment, as shown in FIGS. 1 and 2, the bar magnets 2 and 3 are arranged in parallel. Different polarity parts of the bar magnets 2 and 3 are close or in contact. That is, when looking at the left side of the drawing of the extractor device 1, the N pole side of one bar magnet 2 is in contact with the S pole side of the other bar magnet 3. When looking at the right side of the drawing of the extractor device 1, the S pole side of one bar magnet 2 is in contact with the N pole side of the other bar magnet 3. And the conductor member 5 is wound around the two bar magnets 2 and 3. The winding path of the conductor member 5 around the bar magnets 2 and 3 is in a figure-eight shape as shown in FIG. 2.

[0021] Hereinafter, an explanation will be given in accordance with FIG. 2. As shown in Figure 2(a), the wire member 5 starts from the left end of one bar magnet 2, wraps around to the back of the drawing, and surrounds almost the entire circumference of the bar magnet 2. Its tip then wraps around to the back of the other bar magnet 3, starting from the left end, and surrounds almost the entire circumference of the bar magnet 3. Its tip then returns to the side of the bar magnet 2, wraps around to the back of the drawing, and surrounds almost the entire circumference of the bar magnet 2. This winding is repeated until the wire member 5 is wrapped around both bar magnets 2 and 3. In this embodiment, the conductor member 5 is wound around the entire circumference of the rod-shaped portion of one bar magnet 2 and extends to the adjacent bar magnet 3, and the conductor member 5 is wound around the entire circumference of the rod-shaped portion of the adjacent bar magnet 3 and extends back to the original bar magnet 2.

[0022] In this embodiment, the conductor member 5 is wound around the entire circumference of the rod portion of one bar magnet 2 only once, reaching the adjacent bar magnet 3, and then around the entire circumference of the rod portion of the adjacent bar magnet 3 only once, returning to the original bar magnet 2. However, the present invention is not limited to this configuration, and the conductor member 5 may be wound around the entire circumference of the rod portion of one bar magnet 2 multiple times, reaching the adjacent bar magnet 3, and then around the entire circumference of the rod portion of the adjacent bar magnet 3 multiple times, returning to the original bar magnet 2. When viewed in cross-section with the wire member 5 wrapped around it, as shown in Figure 2(b), the wire member 5 surrounds the entire circumference of both bar magnets 2 and 3, forming an "8" shape.

[0023] Due to the limitations of the diagrams, Figures 1 and 2 depict the wire member 5 with a small number of turns and a large gap between the windings relative to both bar magnets 2 and 3. However, in reality, the wire member 5 has a larger number of turns. In other words, although the conductor member 5 is loosely wound in Figures 1 and 2, it is actually tightly wound. The number of turns in the conductor component 5 is not limited, but it is preferable that it be between 8 and 100 turns. Furthermore, although the conductor member 5 is shown as being wound in a single layer in Figures 1 and 2, it may also be wound in multiple layers, such as double or triple.

[0024] An AC / DC adapter 20 is connected to the conductor member 5, and a direct current is supplied from the AC / DC adapter 20. The direction of current flow to the conductor member 5 does not matter. That is, the polarity of the connection between the AC / DC adapter 20 and the conductor member 5 does not matter. A voltage of 2 volts or higher is preferable.

[0025] Next, the method of using the extract extraction device 1 of this embodiment will be described. Figure 4 shows an example of making a coffee beverage by extracting extract from coffee beans 30 using the extract extraction device 1. To prepare a coffee beverage, water 32 and roasted coffee beans 30 are placed in a designated container 31. The container 31 is preferably made of a material that is not conductive and has low magnetic and electromagnetic shielding properties, such as ceramics or glass, but it may also be made of metal. Coffee Bean 30 is not ground into powder, but rather the beans retain their original shape. Water 32 is at room temperature. The extract extraction device 1 is placed near the container 31, as shown in Figure 4. A direct current is supplied from the AC / DC adapter 20 to the conductive wire member 5 of the extract extraction device 1, and this state is maintained. As a result, coffee extract is released from the coffee beans 30, and the water in the container 31 turns brown. When the desired strength is reached, the coffee beverage is removed from the container 31. According to this embodiment, the active ingredients and flavor components can be extracted to the maximum extent. [Examples]

[0026] The coffee beverage was manufactured using the apparatus shown in Figure 4 and the method described above. The water used was commercially available bottled water. The coffee beans were purchased from a retail store. Container 31 was a clear glass container that came with a commercially available coffee maker. The coffee beans were used at a ratio of 10 grams per 150cc of water. The coffee beans were not ground and retained their shape. Water 32 and roasted coffee beans 30 were placed in container 31, and the extract extraction device 1 was propped up next to container 31. A DC current was supplied to the conductor 5 from the AC / DC adapter 20. The applied voltage was 9 volts. The AC / DC adapter 20 is rated at 9 volts and 2 amperes.

[0027] When this condition was maintained and left unattended, discoloration was observed in the water after about an hour. After approximately 10 hours from the start of power supply, the water had reached a suitable color. The inventor himself tasted the coffee beverage he created, drinking it black, and found it delicious. To ensure objectivity, we had three coffee bean shop employees sample the coffee, and all of them rated it as delicious.

[0028] As a comparative experiment, a coffee beverage (Example Beverage) was produced using the extract extraction apparatus 1 described above. As Comparative Example 1, a coffee beverage (Comparative Example 1) was produced using ground coffee powder and a commercially available coffee maker. As Comparative Example 2, cold brew coffee (Comparative Example 2) was made using ground coffee powder. Ten testers compared the beverages described above, along with Comparative Example 1 and Comparative Example 2. Each coffee beverage was consumed black. The beverages were also compared when heated and at room temperature. As a result, all 10 participants recognized that the three types of coffee beverages differed in taste and flavor. Furthermore, all testers rated the sample beverage as having the best flavor.

[0029] Furthermore, the coffee beverage (example beverage) produced using extract extraction device 1 was stored at room temperature for approximately one year after production, but no spoilage was observed. The taste and flavor also appeared unchanged.

[0030] In the examples described above, the extract extraction apparatus 1 was used in the production of a coffee beverage, but it can also be used when using black tea, green tea, barley tea, etc. It can also be used to manufacture herbal medicines and supplements. Furthermore, the extract extraction device 1 can also be used as a water quality improvement device. Specifically, tap water or other water is placed in a designated container 31. Then, the extract extraction device 1 is placed near the container 31, and a direct current is supplied from the AC / DC adapter 20 to the conductive wire 5, and this state is maintained. After maintaining that state for a certain period of time, the water was removed from container 31. The inventor himself tasted this water and found it to be tastier than tap water. To ensure objectivity, we had over 20 family members and friends sample the drink, and everyone agreed that it tasted better than tap water.

[0031] Furthermore, the water-improved water produced using extract extraction device 1 was sealed in plastic bottles and stored at room temperature for approximately one year, but no spoilage was observed. The taste and flavor also did not appear to have changed significantly.

[0032] In the embodiments described above, an example using two magnets 2 and 3 was shown, but the number of magnets is not limited to two; it may be three or more. However, in order to balance the magnetic force, it is desirable that the number of magnets be even. Figure 5(a) shows an extract extraction device with a structure in which four bar magnets 40, 41, 42, and 43 are arranged in parallel. Figure 5(b) shows an extract extraction device with a structure in which the four bar magnets 40, 41, 42, and 43 are arranged three-dimensionally. In this case as well, the bar magnets 40, 41, 42, and 43 have opposite polarity portions in close proximity or in contact with each other. If a structure is adopted in which bar magnets 40, 41, 42, and 43 are arranged three-dimensionally as shown in Figure 5(b), The conductor material is wound around the entire circumference of the rod-shaped portion of a particular magnet and extends to an adjacent magnet, and the conductor material is wound around the entire circumference of the rod-shaped portion of that adjacent magnet and extends to yet another adjacent magnet.

[0033] While the shape of the magnet is preferably rod-shaped for ease of wrapping the conductive wire member 5, the present invention is not limited to this shape. For example, the magnets 45 and 46 may have a rod-shaped portion and a curved portion, as shown in Figures 5(c) and 5(d). Figure 5(c) shows two magnets 45 and 46 stacked three-dimensionally, and Figure 5(d) shows two magnets 45 and 46 arranged planarly with a horizontal offset. In this case as well, the magnets 45 and 46 have opposite polarity portions in close proximity or in contact. Alternatively, block-shaped magnets may be used. It is desirable for multiple magnets to be as close together as possible, and it is recommended that they be in direct contact with each other.

[0034] In the embodiment described above, the winding path of the conductor member 5 around the bar magnets 2 and 3 is in the shape of an "8," and the conductor member 5 surrounds the entire circumference of both bar magnets 2 and 3, exhibiting an "8" shape. That is, the conductor member 5 intersects between the bar magnets 2 and 3. However, the present invention is not limited to this configuration for the winding path of the conductor member 5, and an elliptical winding path that circles the outer circumference of multiple bar magnets may also be adopted.

[0035] The conductor member 5 used in the above-described embodiment is made up of three metal wires 10, 11, and 12 twisted together, and the materials of the metal wires 10, 11, and 12 are copper, aluminum, and iron. The combination of metal wires 10, 11, and 12 is not limited to these three types, and other combinations are also possible. For example, some of the metal wires 10, 11, and 12 may be made of tin, zinc, lead, gold, silver, etc. Non-metallic wires such as carbon wire may also be included. Furthermore, the metal wires 10, 11, and 12 may be alloys. For example, the combination of metal wires 10, 11, and 12 may be copper, bronze, and brass. However, from the standpoint of ease of availability, low cost, and differences in electrical resistance, the optimal combination of metal wires 10, 11, and 12 is copper, aluminum, and iron.

[0036] The inventions according to the embodiments described above can be substituted or combined as long as no contradictions arise. Furthermore, the above embodiments allow for the free substitution or addition of components between each embodiment, as long as they fall within the technical scope of the present invention.

[0037] In the embodiments described above, a direct current was supplied to the conductor member 5 of the extract extraction device 1, but the supplied current may also be alternating current. For example, as shown in Figure 6, an inverter 21 may be connected to the conductor member 5, and alternating current may be supplied from the inverter 21. The frequency of the alternating current supplied to the conductor member 5 may be a low frequency of a few cycles or a high frequency of about 1000 cycles. The voltage is preferably 2 volts or higher. The AC power supply may also be supplied directly to the conductor member 5 with a 50-cycle or 60-cycle commercial power supply, without going through the inverter 20. However, in this case, it is desirable to reduce the voltage to about 20 volts or less by using a resistor.

[0038] In the embodiments described above, the extract extraction device 1 was placed outside the container 31 as shown in Figure 4. However, as shown in Figure 7, the extract extraction device 1 may be placed inside the container 31 after insulating treatment has been applied to the area around it, such as by resin processing.
