[第一の実施形態]
まず、生のコーヒー豆を用意し、これを常法により、すなわち、コーヒー豆の温度が200℃〜300℃となるように焙煎機を利用して焙煎する。そして、この焙煎工程において発生する300℃程度の高温の空気流であって、匂いガスを含む空気流を回収する。その後、回収した匂いガスを含む空気流を公知の冷却手段を使用して、100℃以下にし、この冷却した匂いガスを含む空気流を、霧状の冷水と接触させてから、この霧状の冷水を10℃以下に冷却することによって、コーヒーの香りを溶存する液体(コーヒーの香りがする液体)を得る。このようにして、本実施形態に係るコーヒー香を有する液体を得る。
[First embodiment]
First, raw coffee beans are prepared and roasted by a conventional method, that is, using a roasting machine so that the temperature of the coffee beans is 200 ° C to 300 ° C. Then, an air flow having a high temperature of about 300 ° C. generated in the roasting process and containing an odor gas is recovered. Thereafter, the air flow containing the recovered odor gas is set to 100 ° C. or lower using a known cooling means, and the air flow containing the cooled odor gas is brought into contact with the mist-like cold water. By cooling the cold water to 10 ° C. or lower, a liquid in which the coffee scent is dissolved (a liquid having a coffee scent) is obtained. Thus, the liquid which has the coffee fragrance which concerns on this embodiment is obtained.

なお、以上の実施形態において行われるすべての工程、すなわち、焙煎、匂いガスを含む空気流の回収・冷却、空気流と霧状の冷水との接触、及び、霧状の冷水の冷却は、密閉空間内において行うことが好ましい。これは、これらの工程を密閉空間内に行うことによって、本発明に係る匂い物質、すなわち、本発明に係るコーヒー香を有する液体における香りの成分を、逃さず回収することができるからである。   In addition, all the steps performed in the above embodiment, namely, roasting, recovery / cooling of the air flow including the odor gas, contact of the air flow with the mist-like cold water, and cooling of the mist-like cold water, It is preferable to carry out in an enclosed space. This is because the odorous substance according to the present invention, that is, the scent component in the liquid having the coffee scent according to the present invention can be recovered without missing by performing these steps in the sealed space.

また、以上の実施形態において、匂いガスを含む空気流を回収する際は、焙煎工程の後半からとすることが好ましい。これは、焙煎工程の前半においては、キャベツ臭等の悪臭が発生するため、焙煎工程の後半から匂いガスを含む空気流を回収することによって、良質なコーヒーの匂い物質のみを回収することができるからである。   In the above embodiment, it is preferable that the air flow including the odor gas is recovered from the latter half of the roasting process. This is because the bad smell such as cabbage odor is generated in the first half of the roasting process, so that only the good coffee odor substance is recovered by collecting the air flow containing odor gas from the second half of the roasting process. Because you can.

さらに、以上の実施形態において、匂いガスを含む300℃程度の高温の空気流は、公知の手段を適宜利用して、その酸化を防止して香りの劣化を防止するようにすることが好ましい。   Furthermore, in the above embodiment, it is preferable that a high-temperature air stream containing about odor gas at a temperature of about 300 ° C. is appropriately used by a known means to prevent its oxidation and prevent deterioration of the scent.

なお、以上の実施形態において、冷却した匂いガスを含む空気流と接触させる霧状の冷水は、噴霧器等を噴霧して得られるものが一例として挙げられる。また、ここでの霧状の冷水は、匂いガスの水中溶存度を確保するため等から、その温度を0℃〜10℃の範囲内とすることが好ましい。   In addition, in the above embodiment, the mist-like cold water contacted with the air flow containing the cooled odor gas can be obtained by spraying a sprayer or the like as an example. Moreover, it is preferable to make the temperature into the range of 0 degreeC-10 degreeC in order to ensure the dissolved degree of the odor gas in the water, etc. here.

なお、以上の実施形態においては、匂いガスを含む空気流と霧状の冷水とを接触させて匂い物質を得ることを特徴としているので、非親水性・揮発性のガスを回収すること無く、ホットコーヒーの匂いと同種かつ親水性であって、良質なコーヒーの匂いを有する匂い物質のみを選択して回収することができると認められる。   In the above embodiment, since it is characterized by obtaining an odorous substance by contacting an air stream containing odorous gas with mist-like cold water, without collecting non-hydrophilic / volatile gas, It is recognized that only odorous substances that are of the same kind and hydrophilicity as hot coffee odor and have a good coffee odor can be selected and recovered.

そのため、本実施形態に係るコーヒー香を有する液体は、コーヒーの豊かな香りが凝縮されたものを含んでおり、当該液体を、通常抽出方法によって得た一定量のコーヒー液と合わせて適温に加熱するだけで、「焙煎したて、挽きたて、淹れたて」の香りにも匹敵するホットコーヒーを、簡単に作ることができる。   Therefore, the liquid having coffee aroma according to the present embodiment includes a condensed coffee rich aroma, and the liquid is heated to an appropriate temperature together with a certain amount of coffee liquid obtained by a normal extraction method. By simply doing, you can easily make hot coffee that matches the scent of “roasted, freshly ground, freshly brewed”.

次に、本発明に係るコーヒー香を有する液体を実施するための第二の形態について説明する。   Next, the 2nd form for implementing the liquid which has the coffee incense based on this invention is demonstrated.

[第二の実施形態]
まず、常法により、コーヒーの抽出を行う。すなわち、粉砕した焙煎済みコーヒー豆を入れたフィルタに熱湯を注ぎ、しばらく蒸らした後に、表面の泡を崩さぬように少しずつ湯を注ぎコーヒーを抽出する。このようにして、粉砕した焙煎済みコーヒー豆とお湯とを接触させ、この際に発生する蒸気を回収する。その後、この回収した蒸気を10℃以下に冷却することによって、コーヒーの香りがする液体を得る。このようにして、本実施形態に係るコーヒー香を有する液体を得る。
[Second Embodiment]
First, coffee is extracted by a conventional method. That is, hot water is poured into a filter containing crushed roasted coffee beans and steamed for a while, and then hot water is poured little by little so as not to break the foam on the surface to extract coffee. In this manner, the crushed roasted coffee beans are brought into contact with hot water, and the steam generated at this time is recovered. Thereafter, the recovered steam is cooled to 10 ° C. or lower to obtain a liquid scented with coffee. Thus, the liquid which has the coffee fragrance which concerns on this embodiment is obtained.

なお、以上の実施形態において行われるすべての工程、すなわち、焙煎済みコーヒー豆とお湯との接触、及び、ここで発生する蒸気の回収・冷却は、密閉空間内において行うことが好ましい。これは、これらの工程を密閉空間内に行うことによって、本発明に係る匂い物質、すなわち、本発明に係るコーヒー香を有する液体における香りの成分を、逃さず回収することができるからである。   In addition, it is preferable to perform all the processes performed in the above embodiment, that is, the contact between the roasted coffee beans and hot water, and the recovery / cooling of the steam generated here in the sealed space. This is because the odorous substance according to the present invention, that is, the scent component in the liquid having the coffee scent according to the present invention can be recovered without missing by performing these steps in the sealed space.

[その他の実施形態]
また、本発明に係るコーヒー香を有する液体を凍結固体化することもできる。即ち、本発明に係るコーヒー香を有する液体の温度を下げ、これを凍結させたものを得ることができる。例えば、本発明に係るコーヒー香を有する液体をドライアイス化したものが得られる。このようにして、本発明に係るコーヒー香を有する液体を凍結固体化したものを製造することもできる。
[Other Embodiments]
Moreover, the liquid which has the coffee scent according to the present invention can be frozen and solidified. That is, the temperature of the liquid having the coffee scent according to the present invention can be lowered to obtain a frozen product. For example, a liquid obtained by converting the liquid having coffee aroma according to the present invention into dry ice is obtained. Thus, what freeze-solidified the liquid which has the coffee fragrance which concerns on this invention can also be manufactured.

さらに、本発明に係るコーヒー香を有する液体を凍結固体化したものを、通常抽出方法によって得た一定量のコーヒー液と合わせ、適温(5℃前後)に加熱するだけで、香り高いアイスコーヒーを得ることができる。   Furthermore, a frozen and solidified liquid with coffee incense according to the present invention is combined with a certain amount of coffee liquid obtained by a normal extraction method, and heated to an appropriate temperature (around 5 ° C.). Obtainable.

なお、本発明に係るコーヒー香を有する液体のドライアイス化は、高圧二酸化炭素を急減圧し少量の水に噴射するとドライアイスになるという特徴を利用して行う。すなわち、ドライアイスを製造する際に、水の代わりに、本発明に係るコーヒー香を有する液体を使用して、ドライアイス化を行うものである。   In addition, the dry ice conversion of the liquid having a coffee scent according to the present invention is performed by utilizing the feature that when high pressure carbon dioxide is rapidly decompressed and sprayed into a small amount of water, it becomes dry ice. That is, when producing dry ice, the liquid having the coffee scent according to the present invention is used to make dry ice instead of water.

本発明に係るコーヒー香を有する液体を得る工程は、すべてコーヒー豆の生産地において行うことが好ましい。通常、ほとんどのコーヒー豆は輸入品であって、焙煎以降の工程のみが日本国内で行われているが、コーヒー香を有する液体を得る工程をすべてコーヒー豆の生産地において行うことによって、コーヒー豆が生鮮食品であることに起因する問題、例えば、カビ、発酵、虫食いなどの品質劣化等や、日本国内での焙煎工程以降に発生する問題、例えば、焙煎後における多孔質コーヒー豆の酸化による品質劣化等の問題を解決することができるからである。また、日本国内における、輸送コストや、品質管理コストも、大きく減少させることができると認められるからである。さらに、日本国内でコーヒーを得る場合、そのコーヒー豆の出し殻の処理が問題となるが、この問題も解決することができるからである。出し殻を、コーヒー豆を生産した農場に返すこととすれば、環境保全の点からも、多大な効果が期待できる。   It is preferable to perform all the steps of obtaining a liquid having a coffee scent according to the present invention in a coffee bean production area. Usually, most coffee beans are imported products, and only the process after roasting is carried out in Japan. However, by performing all the steps to obtain a liquid with coffee aroma in the coffee bean production area, Problems caused by the fact that the beans are fresh food, such as mold, fermentation, worm-eaten quality degradation, problems that occur after the roasting process in Japan, such as porous coffee beans after roasting This is because problems such as quality deterioration due to oxidation can be solved. In addition, it is recognized that transportation costs and quality control costs in Japan can be greatly reduced. Furthermore, when coffee is obtained in Japan, the processing of the ground bean of coffee beans becomes a problem, but this problem can also be solved. If the rice husk is returned to the farm that produced the coffee beans, a great effect can be expected from the viewpoint of environmental conservation.

なお、本発明に係るコーヒー香を有する液体をコーヒー豆の生産地において得た場合には、当該液体は、酸化による品質劣化を防止するため、無酸素容器に入れて日本等の消費国へと出荷することが望ましく、また、当該液体を使用する際は、容器内の窒素ガス圧により液体を放出できる容器に収容し、酸化劣化を防止することが望ましい。   In addition, when the liquid having the coffee aroma according to the present invention is obtained in the coffee bean production area, the liquid is put in an oxygen-free container to a consumer country such as Japan in order to prevent quality deterioration due to oxidation. It is desirable to ship the liquid, and when the liquid is used, it is desirable to store the liquid in a container that can discharge the liquid by the nitrogen gas pressure in the container to prevent oxidative deterioration.
