クハン石を用いたり、活性炭などで濾過したり、あるい
はアルカリ水作製器（特開昭61−97099号公報）などを
用いて味を良くする例が知られている。Conventional technology Conventionally, this type of coffee maker has a structure in which crushed coffee beans, tea, tea leaves, etc. are received by a net or a paper filter, and hot water is poured from the top so that an appropriate extract liquid accumulates at the bottom. Was there. Also, there are some coffee beans such as siphon coffee makers and teapots that have a structure in which beans and leaves are immersed in hot water for extraction. In order to improve the taste of coffee or tea, natural stones or amber stones are used for the water itself, it is filtered with activated carbon, or an alkaline water maker (JP-A-61-97099) is used. There are known examples of improving taste.
発明が解決しようとする課題 従来のこの種のコーヒーメーカーでは、積極的に味を変
化させることは困難であった。Problems to be Solved by the Invention In a conventional coffee maker of this type, it was difficult to positively change the taste.
浄水器や天然石やアルカリ水作製器の場合などは水その
ものに対しある種のイオンを加除することが主眼であ
り、コーヒー中の成分との反応を積極的に図れるもので
はなかった。In the case of water purifiers, natural stones, and alkaline water generators, the main objective is to add or remove certain ions to the water itself, and it has not been possible to positively achieve a reaction with the ingredients in coffee.
また、活性炭を用いる代表例として家庭用浄水器がある
が、一般にこれらの活性炭は常温以下の比較的低温で効
果を有するため、高温での使用はなされていないのが実
情であった。特に熱湯に対しての吸着はあまり効果がな
いと思われていた。In addition, there is a household water purifier as a typical example of using activated carbon, but since these activated carbons generally have an effect at a relatively low temperature below normal temperature, they have not been used at high temperature. In particular, adsorption to hot water was thought to be less effective.
一方、コーヒー中のカフェインは有効成分であり乍らカ
フェインレスのコーヒーが欲しいというときがあった
り、コーヒー中の渋味を抑えたいときなど、その場合に
応じてさまざまな欲求があった。On the other hand, caffeine in coffee is an active ingredient, and there are various desires depending on the case, such as when decaffeinated coffee is desired or when the astringency in coffee is desired to be suppressed.
本発明は上記問題を解決するもので、積極的に味を変化
させることができるコーヒーメーカーを提供することを
目的とするものである。The present invention solves the above problems, and an object of the present invention is to provide a coffee maker capable of positively changing the taste.
課題を解決するための手段 上記問題を解決するために本発明は、粉砕されたコーヒ

着剤を内蔵するフィルタ部を着脱自在にコーヒー抽出部
の下に設けたものである。Means for Solving the Problems In order to solve the above problems, the present invention, in a coffee maker for extracting ground coffee beans and hot water by contact with a drip or siphon, as an adsorbent,
Targeting caffeine as an active ingredient of coffee, activated carbon with an average pore radius distributed around 10Å is used, and a filter part containing this adsorbent is detachably installed under the coffee extraction part. .
作用 上記構成により、コーヒー抽出液がフィルタ部を通過す
るときに、対象の成分を効率よく、吸着し、減少させる
ことができる。Action With the above configuration, the target component can be efficiently adsorbed and reduced when the coffee extract passes through the filter section.
コーヒー抽出液中にはカフェインが1000PPM前後含まれ
ており、高分子黒褐色成分としてたとえばクロロゲン酸
の多量体が考えられるが、このクロロゲン酸も同じよう
に1000PPM前後含まれている。Caffeine is contained in the coffee extract in an amount of about 1000 PPM, and a polymer black-brown component may be, for example, a multimer of chlorogenic acid. This chlorogenic acid is also contained in an amount of about 1000 PPM.
これらの成分は分子量がかなり大きいため、熱湯下でも
吸着剤の細孔分布などを選べば、かなりの吸着能を有す

きる。すなわち、吸着剤として平均細孔半径が10Å付近
に分布した活性炭を使用することにより、分子量194の
カフェインが選択的に吸着除去される。また、平均細孔
半径が30〜100Å付近に分布した活性炭を使用すること
により、コーヒーの不良成分としての高分子黒褐色成分
が選択的に吸着除去される。Since these components have a considerably large molecular weight, they can have a considerable adsorbing ability even when they are heated in hot water by selecting the pore distribution of the adsorbent, and the taste of coffee can be positively changed. That is, caffeine having a molecular weight of 194 is selectively adsorbed and removed by using activated carbon having an average pore radius distributed around 10Å as an adsorbent. Further, by using activated carbon having an average pore radius distributed in the vicinity of 30 to 100Å, a high molecular black-brown component as a poor component of coffee is selectively adsorbed and removed.
