Abstract

PURPOSE:To extract coffee, tea, etc., at an optimum extraction temperature by allowing a passage to pour the water for extraction into an extracting device only in the case where the temperature of the stored water for extraction reaches the melting temperature or higher of the oily substance. CONSTITUTION:A necessary quantity of water is poured into a container 1, and the container 1 is installed in an electronic range, and heating is started. When the temperature of the water for extraction reaches a desired temperature by heating, a film 3 on the bottom part of the container 1 is molten, and the closure of a hole 5' is released and penetration is permitted, and the heated water in the container 1 starts flowing-down to an extraction part 6 from the hole 5'. The hot water contacts the extracted substance in the extraction part 6, and after extraction, the extraction liquid which passes through a filter 7 drops into a receiving device 9, and extraction is completed. After the container 1 and the extraction part 6 are taken out, the receiving device 9 in which the extraction liquid is stored is used directly as a drinking cup. For example, since the film 3 is made of the substance which shows the physical behavior for heat, the passing through the hole 5' at a desired temperature in the range of 30-100 deg.C is permitted, and the optimum extraction liquid temperature can be set for coffee, tea, and other extractable substance.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a simple extractor that is used for extracting coffee, tea, etc. and that enables extraction at a predetermined extraction water temperature, and the extractor. Regarding the extraction method.

[Conventional technology]

Conventionally, for example, the extraction method for regular coffee is
There is a drip type. This extraction method involves placing a brewing device directly on top of a drinking cup, setting a filter paper, etc., placing coffee powder thereon, and then injecting hot water to perform extraction. Here, when injecting hot water, delicate adjustment of the injection amount and injection time (which leads to adjustment of the hot water temperature) is required, and this is thought to affect the flavor etc. of the coffee extract.

On the other hand, with the extraction method of siphon-type or electric coffee makers with built-in heaters, just by setting coffee grounds and brewing water, hot water is semi-automatically generated and injected into the coffee grounds. Extraction is automatically performed in the extraction section. Therefore, these devices do not require adjustment in brewing operation, as is the case with drip-type devices.

[Problem that the invention seeks to solve]

However, conventional regular coffee extraction equipment, such as drip-type extraction equipment, has the drawback that it is difficult to pour hot water into the appropriate amount (mainly the amount and time) because the extraction operation requires skill. was there. On the other hand, with the above-mentioned semi-automatic extraction equipment, automatically heated hot water is uniformly injected into the coffee grounds, making it virtually impossible to adjust the temperature of the hot water for extraction, which is originally necessary. Met. Also,
There were problems in that the extraction device itself was expensive and not compact.

[Means for solving problems]

The present invention has been made in view of the above problems, and
In order to make it possible to extract coffee, tea, etc. with a simple operation and at the optimum extraction temperature for the material to be extracted, we use a member that has at least a part of the liquid-permeable passage and a member that is solid at room temperature. a container for accommodating extraction water having a bottom made of an oily substance that closes the passage; and at least one extraction chamber connected to or bonded to the bottom and accommodating a material to be extracted; an extractor that opens only when the temperature of the extracted water reaches the melting temperature of the oily substance, and the extraction water is injected into the extractor;
The present invention provides an extraction method in which the extractor and the receiver are placed in a predetermined position in a microwave oven and heated for a predetermined time while the extractor is placed on the receiver.

[Effect]

The "oily substance that closes the passage" of the present invention is water-insoluble and does not melt (open the passage) even if it comes into contact with extraction water at a temperature below its melting temperature, so it can reproduce a constant extraction temperature. can do. - Furthermore, since the "oily substance that closes the passage" of the present invention is water-insoluble, it will not dissolve or mix with the extract. Further, simply by injecting a predetermined amount of room temperature water into the extractor (container) of the present invention by heating in a microwave oven, the hot water generation/extraction operation automatically proceeds.

〔Example〕

Hereinafter, the extractor of the present invention will be explained in detail. Figures 1 and 2
The figure shows a first embodiment of the present invention, which includes a container 1 made of a material such as paper, plastic, glass, etc., containing water 2 used for extraction, and a container 1 provided at the bottom 5 of the container 1. A film 3 made of a substance that exhibits physical behavior in response to heat, that is, an oily substance that is solid at room temperature and melts when heated, such as wax, hardened oil, fatty acid, emulsifier, etc. a sheet 4 made of aluminum or other metal coated on the outside of the bottom of the container 1;
An extracting section 6 which accommodates a material to be extracted 8 such as coffee or tea, and has a bottom portion made of a filter made of paper, plastic, metal, etc.;
A mounting film consisting of a receiver 9 made of a material such as glass, the outside of the body and the outside of the bottom covered with a sheet 1O made of aluminum or other metal, and to which the legs 11 made of the material of plastic or paper notes are joined. 3 is formed by coating, spraying, adsorption, etc., but as long as the holes are closed, it is not necessary to form a film on the entire surface.

Although the sheets 4 and 10 are provided for the purpose of blocking waves generated by the microwave oven, they are not necessarily necessary depending on the output of the microwave oven used. For example, in the case of a high-output commercial microwave oven, when the sheet is not present, heat is generated from the bottom of the container 1 or the body and bottom of the receiver 9, and the heat is heated from the bottom of the container 1 or the body and bottom of the receiver 9. The existing liquid will be reheated, and in the worst case, the extract may spill over from the receiver 9, etc., so it is safer to provide the above-mentioned sheet, and it also reduces the aroma from the extract.
Optimal extraction is performed without escaping.

Therefore, it is also possible to use a general coffee cup or the like as the receiver 9. On the other hand, the foot 11 is only needed if a metallic material is used at the bottom of the receiver 9 and there is a risk of sparks.

FIGS. 2(A) and 2(B) show the bottom structure of the container 1, in which a sheet 4 is provided to block electromagnetic waves generated by a microwave oven. Incidentally, the heating appliance is not limited to a microwave oven, and the present invention can be carried out using a sheathed heater, an electric opener, and other heating appliances.

In addition, the shape of the bottom part 5 is not limited to a flat one, but may be an uneven shape, an arch shape, etc., and it is possible to provide the extracting part 6 using this shape. It is possible to obtain surface area and improve extraction efficiency. The above shape is similarly applied to the bottom of the extractor 6 and has a similar effect. On the other hand, it is also possible to provide a plurality of extraction units 6 in series. In addition to the holes 5'' provided in the bottom part 5, other members having liquid-permeable passages, such as filter paper, meshes made of metal or plastic, etc., are applied.

In the above configuration, the extraction process of this example will be explained below.

First, a required amount of water is poured into the container 1, placed in a microwave oven, and after closing the door of the microwave oven, heating is started. The heating time set varies depending on the output of the microwave oven used, but in a household microwave oven, for example, about 1 to 2 minutes is required for the amount of water for one cup of coffee.

Next, when the temperature of the extraction water reaches the desired temperature by heating, the film 3 on the bottom of the container 1 melts, and the hole 5° is unclosed and penetrates, so that the heated water in the container 1 flows through the hole. 5 begins to flow down to the extraction section 6.

The hot water comes into contact with the material to be extracted (coffee powder) in the extraction section 6,
After extraction, the extract that has passed through the filter 7 is dripped into the receiver 9, and the extraction process is completed. Then, after removing the container 1 and the extraction part 6, the receiver i in which the extract is stored is directly used as a drinking cup i. According to this embodiment, the film 3 exhibits physical behavior towards heat. Since it consists of a material, it is possible to penetrate the hole 5° at a wide range of temperature in the range of 31℃ to 100℃, making it possible to maintain the optimum extraction liquid temperature for coffee, tea, and other extractable substances. Can be set.

In the second embodiment, a heat-shrinkable film such as a poly film is used as the film 3 for closing the bottom 5, and by shrinking at a predetermined temperature, holes, tears, etc. are created that open the bottom 5. It is something.

As shown in FIG. 3, the third embodiment improves the thermal responsiveness of a bimetal (for example, Teflon coated), a thermomemory alloy, etc., although the explanation of the parts that overlap with the first embodiment will be omitted. The main components are a member 12 that has a valve 12 and a valve 13 made of rubber or the like that is joined to the member 12 and acts as a valve.

When the extractor with this configuration is heated in a microwave oven, if the temperature of the water in the container l is above a certain temperature, the member 1
2 deforms and lifts the valve 13, the hole 5° passes through, and the following is done.
The extraction step is carried out in the same way as in the first example.

According to this embodiment, since the valve function is provided by the action of the heat-responsive member, the container 1 can be used repeatedly.

〔Effect of the invention〕

As described in detail above, according to the extractor and extraction method of the present invention, the bottom portion is made of a member having at least a liquid-permeable passage and an oily substance that is solid at room temperature and closes the passage. a container for accommodating extraction water, and at least one extraction chamber connected to or bonded to the bottom and accommodating a material to be extracted; The extractor is opened only when the temperature reaches the melting temperature or higher, and the extraction water is poured into the extractor, and the extractor and the receiver are placed in a microwave oven with the extractor placed on the receiver. Since the extraction method involves placing the device in a predetermined position and heating it for a predetermined period of time, coffee, tea, etc. can be extracted with a simple operation and at the optimum extraction temperature for the material to be extracted. In addition, the "oily substance that closes the passage" of the present invention is water-insoluble and will not melt (open the passage) even if it comes into contact with extraction water at a temperature below its melting temperature. Temperature can be reproduced. Furthermore, the "oily substance that closes the passage" of the present invention
Since it is water-insoluble, it will not be dissolved or mixed into the extract.
