本発明は一般家庭用などに使用されるコーヒーメーカー
に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a coffee maker for general household use.
従来の技術
従来、この種のコーヒーメーカーは粉砕されたコーヒー

味を良くするために、水そのものに対し天然の石やバク
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 ground coffee beans, tea, black tea leaves, etc. are placed on a screen or paper filter, and hot water is poured from above, allowing the appropriate extract to collect at the bottom. was. Additionally, there are devices such as saifon-style coffee makers and teapots that have a structure in which beans and leaves are immersed in a pot and then extracted. In order to improve the taste of coffee and tea, we use natural stones or bakuhan stones for the water itself, filter it with activated carbon, or use an alkaline water maker (Japanese Unexamined Patent Publication No. 61-97099). There are known examples of improving the 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 With conventional coffee makers of this type, it has been difficult to actively 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 stone, and alkaline water makers, the main purpose is to add and remove certain ions from the water itself, and it is not possible to actively react with the components 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。特譬こ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。Further, a typical example of using activated carbon is a household water purifier, but since activated carbon is generally effective at relatively low temperatures below room temperature, it has not been used at high temperatures. It was thought that adsorption to hot water was not very 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, although caffeine is an active ingredient in coffee, there are times when people want decaffeinated coffee, or when they want to suppress the astringent taste of coffee, and so on, and there are various desires depending on the situation.
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 aims to provide a coffee maker that can actively change 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、ドリップ式コーヒ
ーメーカーやサイフオン式コーヒーメーカーのコーヒー
抽出部の下にコーヒーの有効成分または不良成分を除去
する吸着剤を内蔵するフィルタ部を着脱自在に設置した
ものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a filter that includes an adsorbent for removing active components or defective components of coffee under the coffee extraction part of a drip coffee maker or a siphon coffee maker. The parts are removably installed.
さらに本発明は、吸着剤として、コーヒーの有効成分と
してのカフェインを対象に、細孔分布が通常のヤシ殼活
性炭より大きく、カフェイン吸着能の高い活性炭、また
はコーヒーの不良成分としての高分子黒褐色成分を対象
に、さらに細孔分布が大きく、高分子成分吸着能の高い
活性炭を使用したものである。Furthermore, the present invention uses activated carbon as an adsorbent for caffeine, which is an active ingredient in coffee, and has a larger pore distribution than ordinary coconut shell activated carbon and has a high ability to adsorb caffeine, or a polymer as a defective ingredient in coffee. Targeting dark brown components, activated carbon with a larger pore distribution and high ability to adsorb polymeric components is used.
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。Effect: With the above configuration, target components 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11000PP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11000PP前後含まれている。Coffee extract contains approximately 11,000 PP of caffeine, and the dark brown polymer component may be, for example, a polymer of chlorogenic acid, which also contains approximately 11,000 PP.
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
るものであり、コーヒーの味を積極的に変えることがで
きる。These components have fairly large molecular weights, so if the pore distribution of the adsorbent is selected, they can have a considerable adsorption capacity even under hot water, and can positively change the taste of coffee.
実施例 以下、本発明の一実施伝を図面に基づいて、説明する。Example Hereinafter, one embodiment of the present invention will be explained based on the drawings.

ルタ部7に注がねる。FIG. 1 is a sectional view of a coffee maker according to an embodiment of the present invention. In FIG. 1, ground coffee beans 1 are placed on a mesh or paper filter 2 and placed on a V-shaped brewing section 3. A predetermined amount of water is put into the water tank 4, and the heater 5
The heated oba is poured into the bean l from above along the arrow a in Fig. 1. Then, the necessary extraction is performed in the extraction section 3, and the liquid falls further downward and is poured into the filter section 7.
第2図はフィルタ部7の拡大図の一例を示す。FIG. 2 shows an example of an enlarged view of the filter section 7. As shown in FIG.
フィルタ部7の吸着剤8として、カフェインを除去した
い場合は、ヤ・シ殼活性炭で細孔分布の比較的大きい、
平均細孔半径が10人付近に分布し、細孔容積が0.3
5 m+/f以との破砕炭(粒径0.15〜1.6U程
度)が選ばれる。If you want to remove caffeine as the adsorbent 8 in the filter section 7, coconut shell activated carbon, which has a relatively large pore distribution, can be used.
The average pore radius is distributed around 10, and the pore volume is 0.3.
Crushed coal of 5 m+/f or more (particle size of about 0.15 to 1.6 U) is selected.
他の吸着剤8として、ゼオライトで平均細孔半径が5〜
15人のものでも良い。また、高分子黒褐色成分を除去
したい場合は平均細孔半径が30〜100人で細孔容積
が0.1 ml /9以とのピッチ系活性炭が良い。Another adsorbent 8 is zeolite with an average pore radius of 5~
It may be for 15 people. Further, when it is desired to remove the blackish brown components of the polymer, pitch-based activated carbon having an average pore radius of 30 to 100 pores and a pore volume of 0.1 ml/9 or more is preferable.

lのコーヒー抽出液当りl−10fを用いれば1回のコ
ーヒー抽出には十分であるが、数回に亘って使用すると
か、長期間使用する場合は吸着能(破過能力)に合せて
増量して用いる。This filter section 7 wraps the adsorbent 8 on its upper and lower surfaces with a metal mesh wire mesh or non-woven fabric such as polypropylene, which allows the coffee extract to pass through without letting the adsorbent 8 pass through. It is made of an impermeable metal such as stainless steel or a molded plastic such as polypropylene. The usage amount of adsorbent 8 is 550m
Using l-10f per l of coffee extract is sufficient for one coffee extraction, but if you use it several times or for a long period of time, increase the amount according to the adsorption capacity (breakthrough capacity). and use it.

きるものである。Effects of the Invention As described above, according to the present invention, by removing caffeine, which is an active ingredient in coffee, it can be used for people who are prone to illness, such as those who do not want to put a burden on their heart or those who want to drink coffee before going to bed. It is very effective for people who should not ingest stimulants, and by removing the black-brown high-molecular components, which are similar to bad components, the sourness and astringency are greatly reduced, giving the product a light taste. You can enjoy coffee that is strong, yet the active ingredients of coffee remain almost the same.
