Description

  The present invention relates to a coffee extraction aid, a coffee extractor, and a coffee extraction method using the same, which suppress deterioration during the coffee extraction process.

  Conventionally, when coffee is exposed to air, particularly oxygen, its components are oxidized, the aroma and flavor are lost, the sourness increases, and so-called deterioration has been a problem. In addition, after extraction of coffee, oxidation of fatty acids contained in the coffee produces oxides and so on, so-called rancidity occurs.Since these oxides have a peculiar odor, they adversely affect the flavor of coffee. It was.

  In view of this problem, for example, in Patent Document 1, an injection pipe is suspended in the container body from the coffee liquid injection port of the lid, and the amount of air entering the container is limited by the vent hole of the injection pipe. A coffee liquid storage container is disclosed.

  Furthermore, Patent Document 2 discloses a coffee liquid storage device that includes a lid body that covers an upper opening of a pot body, has a funnel portion at the center, and further has an extraction port.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 shows and explains the configuration of a coffee extraction aid according to the first embodiment of the present invention. As shown in FIG. 1, a filter 101 for coffee extraction is placed so as to cover an upper opening of a storage container 100 for storing extracted coffee. The coffee extraction aid 1 according to the first embodiment is used with its position fixed so that both ends are gripped between the bottom surface of 101 b and the bottom surface of the storage container 100. In addition to being gripped as described above, the coffee extraction auxiliary tool 1 is attached to the mounting portion 101b with a tape or the like, or provided in advance on the bottom surface of the mounting portion 101b of the filter 101. You may make it latch on a stop part.

  The filter 101 includes a filtering unit 101a in which a paper filter is placed and coffee powder is put in the paper filter, and a mounting unit 101b for mounting the filtering unit 101a on the storage container 100. One or a plurality of holes 101c through which filtered coffee is extracted are formed in the lower surface of the filtration unit 101a.

  The coffee extraction auxiliary tool 1 according to the first embodiment is a flat plate member for receiving coffee dropped from the hole 101c of the filter 101 at a close distance from the hole and guiding it to the bottom of the storage container 100. A flow path having a predetermined inclination angle is formed in a straight line. In the case of a commercially available 700 ml device for 5 cups, there is a height of 10 to 11 cm from the hole 101c to the bottom of the storage container 100 at the start of filtration. Conventionally, when the coffee dripped from the hole 101c falls to the bottom of the storage container 100 as it is, if there is such a height, the collision with the bottom surface of the storage container or the storage liquid surface, and the process of recoil, Due to the undulation of the stored liquid surface, the area and time that the extract was exposed to air increased, oxidation progressed, deterioration progressed, and flavor and the like were reduced. On the other hand, according to the coffee extraction auxiliary tool 1 according to the first embodiment, the dropped coffee is received at a close distance, and thereafter, it is guided to the bottom of the storage container 100 while flowing through the surface, so that it is exposed to air. The degree is reduced, oxidation is suppressed, deterioration is also suppressed, and flavor is maintained.

  As described above, the coffee extraction aid 1 according to the first embodiment is a coffee extraction aid 1 that is used together with the filter 101 and the storage container 100, and one end abuts against the bottom surface of the filter 101 and the other end. Is a coffee extraction aid made of a flat plate member that forms a flow path having a predetermined inclination angle by contacting the bottom surface of the storage container 100.

  This is because the coffee extraction aid 1 is made of a flat plate member having one end abutting against the bottom surface of the filter 101 and the other end abutting against the bottom surface of the storage container 100 to form a channel having a predetermined inclination angle. After the coffee dropped from the pipe is received by a part of the flow path, the coffee extraction method is realized in which the coffee flows on the flow path and is led to the storage container.

Second Embodiment
FIG. 2 shows and explains the configuration of a coffee extraction aid according to the second embodiment of the present invention.

A V-shaped channel is formed. In this case, in the process in which the coffee dripped on the surface of the auxiliary tool 3 flows to the bottom surface of the storage container 102, the possibility of leakage from the surface of the auxiliary tool 3 is further reduced.

  As described above, the coffee extraction aid according to the second embodiment forms a partially curved flow path by having one end in contact with the bottom surface of the filter 101 and the other end in contact with the bottom surface of the storage container 102. The first inclined portion 2a, one end of which is in contact with the bottom surface of the mounting portion 101b of the filter 101, and the first inclined portion 2b are continuous and have a gentler inclination angle than the first inclined portion 2a. The coffee extraction aid 2 includes a receiving portion (for example, a flat portion 2b) and a second inclined portion 2c that is continuous from the receiving portion and has an inclination angle substantially perpendicular to the bottom surface.

  This is composed of a flat plate member that forms a partially curved flow path by one end abutting against the bottom surface of the filter 101 and the other end abutting against the bottom surface of the storage container 102, and one end of the mounting portion 101 b of the filter 101. The first inclined portion 2a that is in contact with the bottom surface of the first and second receiving portions (for example, the flat portion 2b) that is continuous from the first inclined portion 2b and has a gentler inclination angle than the first inclined portion 2a, and continuous from the receiving portion. A coffee extraction aid 2 comprising a second inclined portion 2c having an inclination angle substantially perpendicular to the bottom surface receives the coffee dropped from the filter 101 at the receiving portion, and the second inclined portion continues to the receiving portion. The coffee extraction method for guiding the coffee to the storage container 102 is realized by flowing over 2c.
