Description

【0001】
【発明の属する技術分野】
本発明は、飲料抽出装置に関するものである。
【0002】
【従来の技術】
従来、飲料抽出装置としては、例えば特開平1−158592号公報に記載されたものが知られている。
【0003】
以下、図面を参照しながら上記従来の飲料抽出装置を説明する。図12は、従来の飲料抽出装置の概略構成図である。
【0004】
図12において、1は、コーヒー等の飲料原料9と湯12が混合されるシリンダ、2はシリンダ1の下面開口部、3は下面開口部2を覆うフィルタ、4はフィルタ3を下面開口部2に押し付けるろ過液受け、5はシリンダ1の上面開口部、6は上面開口部5を閉じる弁機構、7は弁機構6を駆動する弁機構被駆動軸、8は飲料原料9を貯蔵する貯蔵・搬出装置である。
【0005】
10は湯弁11を介しシリンダ1に湯12を供給する温水タンク、13はシリンダ1上部に形成され、シリンダ1方向へ下方に傾斜した原料受け、14は原料受け13へ飲料原料9を投入するシュート、15は飲料原料と湯の混合液である。
【0006】
16はシリンダ上部のエア上部導入口17とシリンダ下部のエア下部導入口18に連結されたエアポンプ、19はシリンダ上部のエア上部導入口17とシリンダ下部のエア下部導入口18のいずれかにエアを送る3方切替え弁、20はシリンダ内に湯を流し込む給湯ノズルであり、21は、湯弁11と連通し、温水タンク10から吐出された湯を給湯ノズル20に注ぐ湯注入管である。
【0007】
以上のように構成された飲料抽出装置について、以下その動作を説明する。
【0008】
まず、待機状態では、弁機構6は開いており、ろ過液受け4はシリンダ1の下方にあり、シリンダ1とは接触していない。
【0009】
販売信号により、フィルタ3を上面にのせたろ過液受け4は上方に移動してシリンダ下部を塞ぐと、貯蔵・搬出装置8より飲料原料9がシュート14を介して原料受け13へ投入され、湯弁11を介して温水タンク10より送出された湯12が湯注入管21を通り給湯ノズル20より原料受け13上に流れ、原料受け13上にある飲料原料9をシリンダ1内に流し込む。
【0010】
シリンダ1内の飲料原料9と湯12の混合液15中に、エアポンプ16より3方切替え弁19を介して下部エア導入口18に所定時間空気が吹き込まれる。この注入された空気により、混合液15は攪拌され飲料原料9より飲料のエキス抽出が促進される。
【0011】
混合液15のエアによる攪拌終了後、シリンダ1内で飲料原料と湯は所定時間滞留した後、弁機構駆動装置7により弁機構6がシリンダ1の上面開口部5を閉じ、空気がエアポンプ16より3方切替え弁19によって上部エア導入口17よりシリンダ1内に吹き込む。
【0012】
シリンダ1内は加圧されて、混合液15は下面開口部2よりフィルタ3を通過し、ろ過液受け4に強制ろ過されて図12には示されていないカップへ抽出液が送出されると、弁機構6が開きろ過液受け4が下方に移動し、シリンダ1内の湯を含んだ飲料原料のかすがフィルタ3上に落ちフィルタ3が送出されて抽出かすがシリンダ1の下方から移動すると待機状態に戻る。
【0013】
【発明が解決しようとする課題】
しかしながら、従来の飲料抽出装置では飲料原料9と湯12の混合液15をエアで強制的に激しく攪拌することで抽出液が酸化し、渋味が強くなり飲料の味が落ちるという欠点があった。
【0014】
本発明は従来の課題を解決するもので、渋味が少なく抽出濃度が高い、おいしい飲料の抽出ができる、飲料抽出装置を提供することを目的とする。
【0015】
【課題を解決するための手段】
本発明の請求項1に記載の発明は、上下に開口部を有するシリンダの下面開口部にフィルタを配置し前記シリンダの上面開口部から前記シリンダ内に飲料原料と湯を供給した後、前記上面開口部を閉じて前記シリンダ内に空気を圧入して、前記フィルタでろ過された飲料を得るものであって、前記シリンダ内に湯を供給する湯注入管の出口に複数の湯放出孔を有するプレートを保持した給湯ノズルを備え、前記シリンダ内に湯を供給する際に前記給湯ノズルの前記プレートが前記シリンダの前記上面開口部の中央の上方に位置するように構成したものにおいて、前記プレートは給湯ノズルの下端より上方に位置し、前記給湯ノズルの下端は先細のテーパ形状とするとともに、前記給湯ノズルの内面は上方から下方に向かって外側に広がる構造とし、前記湯放出孔から放出される湯の一部が前記テーパ形状に沿って流れ、前記シリンダの内壁に当たる湯を減らして前記シリンダ内に注ぐものであり、シリンダの上面開口部の中央の上方に位置するプレートの複数の湯放出孔から湯がシリンダ内部の飲料原料の広範囲に注がれるため、飲料原料と湯の接触面積が増え、エアで強制的に攪拌を行わなくても高濃度の飲料が抽出でき、エアで強制的に攪拌しないので飲料原料と湯の混合液の空気による酸化が少なくなって渋味の少ない抽出ができるという作用を有する。さらに、飲料原料と湯の混合液にエアを吹き込む必要がないので、エアポンプの動作時間が減少し、エアポンプの寿命が長くなるという作用も有する。また、飲料原料の充填率の低いシリンダ内壁に注ぐ湯を減らし、シリンダ内部の飲料原料に当たり易くすることで、さらに飲料原料のエキスの抽出がより促進され、高い濃度でおいしい飲料が抽出されるという作用を有する。
【0016】
請求項2に記載の発明は、請求項1に記載の発明に、さらに、給湯ノズル内部の湯注入管先端とプレートとの間に網状部材を設けたものであり、湯注入管内を湯が不均一に流れてきた場合でも網状部材により湯の流れの偏りがなくなりプレートの全面により均一に湯が当たり、プレートの各湯放出孔から均一に湯が分散して放出され、シリンダ内の飲料原料に湯がより均一に注がれ、飲料原料のエキスの抽出が促進され、請求項1に記載の作用に加えてさらに高濃度でおいしい飲料を抽出できるという作用を有する。
【0018】
請求項に記載の発明は、請求項1または2に記載の発明において、給湯ノズルが弾塑性材料で構成されており、前記給湯ノズルを所定の形に変形させたときにプレートが着脱可能なように前記プレートの外周部を前記給湯ノズルの内面に周方向に形成した溝に挿入保持させたものであり、プレートの着脱が容易であり、プレートの清掃が行い易く、プレートの定期的な清掃で、継続的にシリンダ内にシャワー状給湯することができるので、常に高い濃度でおいしい飲料が抽出されるという作用を有する。
【0019】
請求項に記載の発明は、請求項1からのいずれか一項に記載の発明において、給湯ノズルへ差し込まれた湯注入管先端とプレートの中心との距離を2mm以上で8mm以下としたものであり、湯が給湯ノズルの内面を沿って流れる等によりプレートに偏って湯が当ることが少なくなることで、プレートの湯放出孔から湯が均等に放出されやすくなり、請求項1および請求項2に記載の作用に加えてさらに飲料原料のエキスの抽出がより促進され、高い濃度でおいしい飲料が抽出されるという作用を有する。
【0022】
【発明の実施の形態】
以下、本発明による飲料抽出装置の実施の形態について、図面を参照しながら説明する。なお、従来と同一構成については、同一符号を付して、詳細な説明を省略する。
【0023】
(実施の形態1)
図1は、本発明の実施の形態1による飲料抽出装置の概略構成図を示し、図2は同実施の形態の給湯ノズルおよびプレートを示す要部断面拡大図である。図3は、同実施の形態の飲料抽出装置の待機状態におけるシリンダと弁機構と給湯ノズルとろ過液受けを示す概略図、図4は、同実施の形態の飲料抽出装置のエア送出中におけるシリンダと弁機構と給湯ノズルとろ過液受けを示す概略図である。
【0024】
図1において、8aは固定シュートであり、貯蔵・搬出装置8の下部に取付けられており、飲料原料9が貯蔵・搬出装置8内より固定シュート8aを通過し移動シュート25上へ落ちる。23はシュート回動駆動装置であり、軸24により回転自在に上端を軸支された移動シュート25を駆動する。
【0025】
26は上面が略円錐状に開口したシリンダ、28は給湯ノズル22にとりつけられ湯を放出するための複数の湯放出孔28aをもつプレートである。
【0026】
30は、図示しない駆動装置に連結された被駆動軸であり、31は一端が被駆動軸30に固定された軸体である。また、軸体31の他端に弁機構6を連結している。32は軸体31に設けられ、軸体31に湯注入管27を固定する固定具である。
【0027】
そして、飲料抽出装置が待機状態およびシリンダ26内に湯を給湯する時には給湯ノズル22がシリンダ26の上面開口部中央の上方に位置し、抽出が終わりエアでシリンダ26内の混合液15を抽出する時には、弁機構6がシリンダ26内の上面開口部33を密閉する位置にくるように、被駆動軸30と軸体31と固定具32と湯注入管27と湯注入管27の先端にある給湯ノズル22は、回動、および上下方向に移動する。
【0028】
また、図2に示すように、給湯ノズル22に設置されているプレート28は、複数の湯放出孔28aを持つ上に凹、下に凸の曲面形状をなしシリンダ26内に湯をシャワー状に流下する。
【0029】
以上のように構成された飲料抽出装置について、以下その動作を説明する。
【0030】
待機状態では図3に示すように、プレート28を保持する給湯ノズル22がシリンダ26の上面開口部33の中心上方にくるように設置されており、フィルタ3を上方に載せたろ過液受け4はシリンダ26の下方にあるが、下面開口部2を塞いではいない。
【0031】
販売信号によりろ過液受け4は上昇しフィルタ3を介してシリンダ26の下面開口部2を塞ぐ。その後、シュート駆動回転装置23が移動シュート25を軸24を中心に回動し、飲料原料9がシリンダ26の中央付近に落ちる位置に保持する。
【0032】
その後、飲料原料9が固定シュート8aを通過し、移動シュート25上に落ちた後、シリンダ26内にすべり落ちる。そして、飲料原料9がシリンダ26内に投入し終わると、移動シュート25は待機状態に戻る。
【0033】
その後、温水タンク10の湯弁11が開き、湯12が湯注入管27を通過し給湯ノズル22内に注がれ、プレート28にある複数の湯放出孔28aより、シャワー状に湯12がシリンダ26内に放出され飲料原料9と湯12が攪拌されて、飲料のエキスが抽出される。
【0034】
その後、湯弁11が閉じ、飲料原料9と湯12の混合液15がシリンダ26内で滞留した後、被駆動軸30が回転降下し、被駆動軸30と連動して動く弁機構6は、エア上部導入口17より上の位置で上面開口部33を閉じる(図4)。
【0035】
そして、空気がエアポンプ16によりエア上部導入口17からシリンダ26内へ吹き込まれ、シリンダ26内は加圧されて混合液15は下面開口部2よりフィルタ3を通過しろ過液受け4に強制ろ過され飲料が抽出され、ろ過液受け4の排出口から図中には示していないカップへ送出される。
【0036】
カップへ飲料の送出が完了すると、被駆動軸30が上方へ移動することで弁機構6も同時に上昇しシリンダ26より離れ、さらに被駆動軸30は回転し、給湯ノズル22がシリンダ26の上面開口部33の中央上方位置にくると停止する。同時にろ過液受け4は下降し、シリンダ26の下面開口部2から離れると、シリンダ26内の抽出完了後の、湯を含んだ飲料原料はろ過液受け4上のフィルタ3上に落下し、フィルタが図にはないカスバケツの方へフィルタ3が引張られることによりフィルタ3上に落下した湯を含んだ飲料原料がカスバケツの方へ移動し、待機状態に戻る。
【0037】
以上のように本実施の形態の飲料抽出装置は、複数の湯を放出するための湯放出孔28aをもつプレート28を備えた給湯ノズル22をシリンダ26内に給湯する際に、シリンダ26内の上面開口部33の中央上方に位置するように設置することにより、湯12がシリンダ26内部の広範囲に注がれ飲料原料9と湯12を混合し、濃度が高い飲料エキスの抽出が出来るので、濃度が高い飲料の抽出ができ、さらに従来行われていたエアを飲料原料9と湯12の混合液15に吹き込み、飲料原料9と湯12の攪拌を行わないので、空気による酸化が少なく渋味が少ないおいしい飲料が抽出できる。
【0038】
(実施の形態2)
以下、本発明による飲料抽出装置の実施の形態2について、図面を参照しながら説明する。なお、従来および実施の形態1と同一構成については、同一符号を付して詳細な説明を省略する。
【0039】
図5は、本発明の実施の形態2による飲料抽出装置の給湯部40の断面図である。
【0040】
図5において、34は給湯ノズル22内において、湯注入管の先端とプレート間に設けられた網状部材である。
【0041】
本実施の形態における飲料抽出装置は、図2に示された実施の形態1における給湯部40を、図5に示すように、湯注入管27の先端とプレート28の間に網状部材34を取り付けたものに置き換えたものであり、その他の構成は実施の形態1と同一である。
【0042】
本実施の形態では、湯注入管27を湯が通過した後、網状部材34を通過し湯が整流化された後、プレート28の湯放出孔28aからシリンダ26内に湯が供給される。
【0043】
以上のように本実施の形態の飲料抽出装置は、湯が網状部材34を通過することで、細かく分散されて整流化されることにより、整流され湯量の違い等で湯注入管27内を湯が不均一に流れてきた場合においても、給湯ノズル22内のプレート28の複数の湯放出孔28aに湯がより均一に供給され、複数の湯放出孔28aからシリンダ26内全面に、より均一な強さのシャワー状給湯が行われるので、より濃度が高くおいしい飲料の抽出が可能となる。
【0044】
(実施の形態3)
以下、本発明による飲料抽出装置の実施の形態3について、図面を参照しながら説明する。なお、従来および実施の形態1および2と同一構成については、同一符号を付して詳細な説明を省略する。
【0045】
図6は、本発明の実施の形態3による飲料抽出装置の給湯部40の断面図である。
【0046】
本実施の形態における飲料抽出装置の概略構成図は、図1に示された実施の形態1および2における給湯部40を、図6に示すように、プレート28が設置された位置より下部の、給湯ノズル22の下端35aは先細のテーパ形状で給湯ノズル35の内面はプレート28より下方の部分がプレート28の上方の部分より大きく外側に広がっているものに変えたものであり、シリンダ26内に給湯する際に、プレート28の中心から離れ給湯ノズル35とプレートの取付け位置に近い位置に開けられている湯放出孔28aから放出した湯は給湯ノズル35の下端35aの内側のテーパ部に沿ってシリンダ26内に流れる。
【0047】
以上のように本実施の形態の飲料抽出装置は、給湯ノズル35の内部を給湯ノズル35のプレート28より下方の部分を前記のテーパ形状としたものに変えることにより、プレート28の湯放出孔28aから放出される湯の一部がテーパ部を添ってシリンダ26内に注がれるので、シリンダ26の内壁に当たる湯が減り、シリンダ26内壁付近の飲料原料9の充填率の低い部分に注ぐ湯12の割合が減少するので、より多くの飲料原料9の表面に湯12が接触し、飲料原料9のエキスの抽出が促進され、高濃度でおいしいコーヒーが抽出される。
【0048】
(実施の形態4)
以下、本発明による飲料抽出装置の実施の形態4について、図面を参照しながら説明する。なお、従来および実施の形態1および2および3と同一構成については、同一符号を付して詳細な説明を省略する。
【0049】
図7は、本発明の実施の形態4による飲料抽出装置の給湯ノズル50にプレート51の断面図である。
【0050】
本実施の形態における飲料抽出装置の概略構成図は、図1に示された実施の形態1および2および3における給湯ノズルとプレートを、給湯ノズル50はシリコン等の弾塑性材料で製作し、図7に示すように、給湯ノズル50の下部内面にプレート51が保持できるようにプレート51の外周形状にあわせた溝を設け、この溝部分にプレート51の側面を挿入することのみで給湯ノズル50にプレート51を設置することができる形状としたものである。
【0051】
給湯ノズル50にプレート51をネジ等を用いて固定しているのではないので、道具を用いる必要がなく、ワンタッチで容易に給湯ノズル50からプレート51を取り外しできるので、プレート51の清掃が行い易くプレート51の穴がスケール等で詰まることなく均一な状態でシリンダ内にシャワー状給湯することができるので、常に高い濃度でおいしい飲料が抽出される。
【0052】
(実施の形態5)
以下、本発明による飲料抽出装置の実施の形態5について、図面を参照しながら説明する。なお、従来および実施の形態1および2および3および4と同一構成については、同一符号を付して詳細な説明を省略する。
【0053】
図8は、本発明の実施の形態5による飲料抽出装置の給湯ノズル50と湯注入管27とプレート51の断面図である。
【0054】
図8において、Bは、湯注入管27とプレート51の中心との距離を表す。
【0055】
また、図9は、湯注入管27とプレート51の中心との距離Bと飲料抽出液の濃度の関係を示した図である。湯注入管27とプレート51の中心間距離Bが5mmの場合において飲料抽出液濃度は最大の値となっており、湯注入管27とプレート51の距離Bを2mm〜8mmの長さとすると高濃度の抽出液が得られる。
【0056】
湯注入管27とプレート51の距離Bが2mm〜8mmの長さとした場合には、湯注入管から吐出した湯12がプレート51に均一に当たり、プレート51の湯放出孔51aから均一に湯12が放出され、シリンダ26内の飲料原料9に均一に湯12が当たるので濃度が高くおいしい飲料が抽出できる。
【0057】
(実施の形態6)
図10は、本発明の実施の形態6による飲料抽出装置の概略構成図を示し、図11は同実施の形態の弁機構60およびプレート61および湯注入管27を示す要部断面拡大図である。
【0058】
図10において、60は弁機構であり、中心軸が空洞となっている。61は、弁機構60の中心に取付けられた、湯を放出するための複数の湯放出孔61aもつプレートである。
【0059】
62は、図示しない駆動装置に連結された被駆動軸であり、63は一端が被駆動軸62に固定された軸体である。また、軸体63の他端に弁機構60を連結している。
【0060】
66は、弁機構60の中心軸の空洞部に湯が流れるために湯注入管27と弁機構60を接続する、接続口である。
【0061】
また、図11に示すように、弁機構60の中心軸は中空となっており、弁機構60の中心軸を湯が流れ、弁機構の下端中央に取付けられたプレート61は、複数の湯放出孔61aを持つ上に凹、下に凸の曲面形状をなし、シリンダ26の上面開口部を弁機構60で閉じた状態で、湯をシリンダ26内にシャワー状に流下する。
【0062】
64は、空気孔であり、湯弁11が開き温水タンク10から湯が放出される場合には、空気孔64は開放状態であり、湯が温水タンク10から湯注入管27へ流れていく。
【0063】
また、65は空気孔弁であり、抽出した飲料をシリンダ26内からカップへ送出する際には空気孔64をふさぐ機構となっている。
【0064】
以上のように構成された飲料抽出装置について、以下その動作を説明する。
【0065】
待機状態では、シリンダ26の上面開口部33は弁機構60で塞がれてはおらず、フィルタ3を上方に載せたろ過液受け4はシリンダ26の下方にあるが、下面開口部2を塞いではいない。
【0066】
販売信号によりろ過液受け4は上昇しフィルタ3を介してシリンダ26の下面開口部2を塞ぐ。その後、シュート駆動回転装置23が移動シュート25を軸24を中心に回動し、飲料原料9がシリンダ26の中央付近に落ちる位置に保持する。
【0067】
その後、飲料原料9が固定シュート8aを通過し、移動シュート25上に落ちた後、シリンダ26内にすべり落ちる。そして、飲料原料9がシリンダ26内に投入し終わると、移動シュート25は待機状態に戻る。
【0068】
その後、被駆動軸62が回転降下し、被駆動軸62と連動して動く弁機構60は、エア上部導入口17より上の位置で上面開口部33を閉じる。
【0069】
そして、温水タンク10の湯弁11が開き、湯12が湯注入管27を通過し、弁機構60の中空部分を通過し、プレート61にある複数の湯放出孔61aより、シャワー状に湯12がシリンダ26内に放出され飲料原料9と湯12が攪拌されて、飲料のエキスが抽出される。
【0070】
その後、湯弁11が閉じ、飲料原料9と湯12の混合液15がシリンダ26内で滞留した後、空気孔弁65が空気孔64をふさぎ、空気がエアポンプ16によりエア上部導入口17からシリンダ26内へ吹き込まれ、シリンダ26内は加圧されて混合液15は下面開口部2よりフィルタ3を通過しろ過液受け4に強制ろ過され飲料が抽出され、ろ過液受け4の排出口から図中には示していないカップへ送出される。
【0071】
カップへ飲料の送出が完了すると、被駆動軸62が上方へ移動することで弁機構60も同時に上昇しシリンダ26より離れ、さらに被駆動軸62は回転し、弁機構60がシリンダ26の上面開口部33の中央上方位置から移動シュート25と反対側に移動し停止する。
【0072】
同時にろ過液受け4は下降し、シリンダ26の下面開口部2から離れると、シリンダ26内の抽出完了後の、湯を含んだ飲料原料はろ過液受け4上のフィルタ3上に落下し、フィルタが図にはないカスバケツの方へフィルタ3が引張られることによりフィルタ3上に落下した湯を含んだ飲料原料がカスバケツの方へ移動し、待機状態に戻る。
【0073】
以上のように本実施の形態の飲料抽出装置は、弁機構60の中心軸が中空となっており、さらに複数の湯を放出するための湯放出孔61aをもつプレート60を弁機構60の中心に備えているので、弁機構60がシリンダ26の上面開口部33を塞いだ状態で、湯弁11が開き、湯注入管を通過した湯が弁機構の中心を通りプレートからシリンダ26内の飲料原料にシャワー状に給湯できる。したがって、飲料原料9と湯12が接触し飲料のエキスを抽出する際に、湯12の蒸気がシリンダ26内からもれることがなくシリンダ26内での湯12の温度降下が減少し、高い湯温で抽出できるので高濃度でおいしい飲料の抽出ができる。
【0074】
【発明の効果】
以上説明したように請求項1に記載の発明は、シリンダ内に湯を供給する湯注入管の出口に複数の湯放出孔を有するプレートを保持した給湯ノズルを備え、前記シリンダ内に湯を供給する際に前記給湯ノズルの前記プレートが前記シリンダの前記上面開口部の中央の上方に位置するように構成したものにおいて、前記プレートは給湯ノズルの下端より上方に位置し、前記給湯ノズルの下端は先細のテーパ形状とするとともに、前記給湯ノズルの内面は上方から下方に向かって外側に広がる構造とし、前記湯放出孔から放出される湯の一部が前記テーパ形状に沿って流れ、前記シリンダの内壁に当たる湯を減らして前記シリンダ内に注ぐものであり、シリンダの上面開口部の中央の上方に位置するプレートの複数の湯放出孔から湯がシリンダ内部の飲料原料の広範囲に注がれるため、エアで強制的に攪拌を行わなくても高濃度の飲料が抽出でき、エアで強制的に攪拌しないので飲料原料と湯の混合液の空気による酸化が少なくなって渋味の少ない抽出ができる。さらに、飲料原料と湯の混合液にエアを吹き込む必要がないので、エアポンプの動作時間が減少し、エアポンプの寿命が長くなる。さらにまた、飲料原料の充填率の低いシリンダ内壁に注ぐ湯を低減し、飲料原料と湯の接触面積が増加し、飲料原料のエキスの抽出がより促進され、より高い濃度で安定したおいしい飲料が抽出できる。
【0075】
また、請求項2に記載の発明は、請求項1に記載の発明に加えて、湯注入管先端とプレート間に網状部材を取り付けたものであり、湯が網状部材を通過した湯は、プレートの複数の湯放出孔からより均一に分散して放出されるので、シリンダ内の飲料原料に湯がより均一に注がれ、請求項1の効果に加えてさらに飲料原料のエキスの抽出がより促進できる。
【0077】
請求項に記載の発明は、請求項1または2に記載の発明に加えて、給湯ノズルが弾塑性材料で構成されており、前記給湯ノズルを所定の形に変形させたときにプレートが着脱可能なように前記プレートの外周部を前記給湯ノズルの内面に周方向に形成した溝に挿入保持させたものであり、プレートの着脱が容易であり、プレートの清掃が行い易く、プレートの定期的な清掃で、継続的にシリンダ内にシャワー状給湯することができるので、常に高い濃度でおいしい飲料が抽出される。
【0078】
