Description

【０００１】
【発明の属する技術分野】
本発明は、お茶のほか、胡麻、麦、そば等の穀物類等を適度な粒度（細かさ）の粉末に粉砕するための粉砕機の改良に関する。
【０００２】
【従来の技術】
お茶は趣向品であるばかりではなく、健康食品として親しまれている。お茶にはビタミンやミネラルが豊富に含まれており、そのままのお茶を単にお湯によって出したのでは茶がらに上記の栄養分の大半が残ってしまい、栄養素の摂取ができない状態になる。そのため、葉茶を粉末茶にし、これをお湯により出せば上記栄養素の充分の摂取が可能になる。
ところで、現在、葉茶を粉末茶にする粉砕機としては、一般的には粉砕面が平面の石臼が使用されている。
【０００３】
【発明が解決しようとする課題】
しかしながら上記石臼は、上臼と下臼の対向する粉砕面が互いに平面形状のため、粉砕面における滞留時間が短くなって適度な粒度の粉末茶が得られないことがあった。この解決策としては臼の粉砕面における滞留時間を長くするために大きな直径のものを使用して粉砕工程を長くすることも考えられるが、かかる方法は装置の大型化が避けられないと同時に駆動用の動力も大きなものが必要となって好ましくない。
【０００４】
そこで、本願発明者は上記問題点を解決するために、先に特願平６−２７２８１９号により、図１０に示すような技術を提供した。この技術を以下先願技術という。
この図１０に示す粉砕機は、内面１０１ａ側に摺鉢状の粉砕面１０１ｂを備えたセラミックス製の下臼１０１と、外面１０２ａ側に形成した粉砕面１０２ｂが上記下臼１０１の粉砕面１０１ｂと合致すると共に内面１０２ｃ側に漏斗形のホッパ−部１０２ｄを形成したセラミックス製の上臼１０２と、上臼１０２を回転駆動するための駆動装置１０３とから構成された新規な小（卓上）型の粉砕機である。
【０００５】
上記先願技術の粉砕機は、従来の石臼タイプのものに比べて小型で構造がシンプルなため取り扱いがし易い等の点で優れているが、例えば葉茶ａの種類によっては投入した葉茶ａが上臼のホッパ−部１０２ｄ内でブリッジ状に絡み合いを起こし、上臼１０２の下部に設けた材料排出口１０２ｅ付近で葉茶（材料）が停滞して粉砕面側への移動（供給）がスム−ズに行えないことがある。
【０００６】
また、上記先願技術の粉砕機は粉砕面で粉砕された粉末茶が上臼１０２と下臼１０１の接合端面イの排出口から排出される方式であるが、その処理物（粉末茶）が受け皿（部）１０４上に落ちて滞積し、排出口へスム−ズに誘導されないことがある。
【０００７】
また、上記先願技術の粉砕機には粉砕粒度を調整する目的のため角度変更装置１０５を設けて臼体を傾斜運転（駆動）するようにしているが、該角度変更装置は構造が複雑のためコスト高の要因になっている。
【０００８】
【課題を解決するための手段】
本願発明は上記先願技術における諸々の問題点をさらに解決するためのもので、第１の発明は、内面（８ａ）側に摺鉢状の粉砕面（８ｂ）を備えた下臼（８）と、外面（１５ｃ）側に形成した粉砕面（１５ａ）が上記下臼（８）の粉砕面（８ｂ）と合致すると共に内面（１５ｅ）側に漏斗形のホッパ−部（１５ｄ）を形成した上臼（１５）と、上臼（１５）を回転するための回転駆動装置（２５）と、これらを収納するための本体ケ−ス（２）とからなるものにおいて、上記本体ケ−ス（２）には粉砕処理物を受け止めるための受け皿部（３ａ）を設けると共にさらに本体ケ−ス（２）側には上臼（１５）のホッパ−部（１５ｄ）内に供給された粉砕未処理物を上臼（１５）の回転に伴って撹拌するようにした撹拌部材（２１）を付設し、更に、前記本体ケ−ス（２）には所定の傾き角度で拘束できる運搬用の持ち手（３６）を付設し、また本体ケ−ス（２）の下部には滑り止め部材（３７）を設けて粉砕機（１）の傾斜運転を可能にしたことを特徴とする粉砕機を提案するものである。
本発明によれば、上蓋ケ−スに撹拌部材（２１）を付設し、この撹拌部材（２１）により上臼のホッパ−部内の未処理物（葉茶ａ）を上臼（１５）の回転に伴って撹拌するようにしたため、ホッパ−部（１５ｄ）に投入された未処理物はブリッジ状に絡まることなく上臼の下部の材料排出口より粉砕面にスム−ズに排出される。更に、持ち手（３６）の角度を変更するのみで機体を所望の角度に傾斜設置できる。
【０００９】
また、第２の発明は、前記第１の発明において、上臼（１５）側には掃き出し部材（１７ｂ）を付設し、該掃き出し部材（１７ｂ）が上臼（１５）の回転に伴って受け皿部（３ａ）に滞積した粉砕処理物を受け皿部（３ａ）に連接する掃き出し口（３ｃ）方向に掃き出すようにしたことを特徴とする粉砕機を提案するものである。
本発明によれば、粉砕面で微粉末に粉砕された処理物、例えば粉末茶（ｂ）は上下両臼の接合端面から受け皿部（３ａ）に排出（落下）するが、この排出された粉末が受け皿（３ａ）部に滞積した場合にも、上臼側に設けて上臼の回転に伴って一緒に回転する掃き出し部材（１７ｂ）により掃き出し口（３ｃ）へ向かって強制的に掃き出される。更に、持ち手（３６）の角度を変更するのみで機体を所望の角度に傾斜設置できる。
【００１１】
【発明の実施の形態】
以下、図１乃至図９に示す実施例に基づいて本発明の実施の形態について説明する。
図中１は粉砕機であり、一例として卓上型を示す。２は合成樹脂製の本体ケ−スであり、同ケ−ス２は後述の上、下臼を収納するための上部ケ−ス３と、回転駆動装置等を収納するための下部ケ−ス４と、上部ケ−ス３を上方から覆うようにして中間部ケ−ス５に開閉自在に軸着した上蓋ケ−ス６と、上部ケ−ス３と下部ケ−ス２間を連結するための上記中間部ケ−ス５と、下部ケ−ス４の下端開口部４ａを閉鎖するように同部に止着した底蓋ケ−ス７とから構成されている。
【００１２】
８は上記上部ケ−ス３に収納され、その内面８ａ側に摺鉢状の粉砕面８ｂを形成したアルミナ磁器、普通磁器、陶器等のセラミックス製の下臼である。該下臼８の中央下面には合成樹脂製の取付補助台９が、その突出部９ａを下臼８に形成した貫通孔８ｃに下方から挿入して合体されている。なお、合体に際しては下臼８の取付用突出部８ｄと取付補助台９の突出部９ａの間に接着剤１０を注入して両者を一体に合体している。また上記貫通孔８ｃには、その上部に位置して丸穴からなる軸穴１１ａを形成した穴部材１１が接着固定されている。更に上記下臼８の内面（上面）８ａ側には図２に示すように複数の平行溝からなる主溝８ｈとその主溝８ｈに対し交差する方向にその向きを変更した副溝８ｊからなる粉砕面８ｂが形成されている。
９ｂは取付補助台９の側周面に形成した取付凹部であり、同部は円周に沿って均等間隔に３カ所設けられており、該補助台９は、中間部ケ−ス５の上部の受け部５ａ上にベ−ス金具１２と共にネジ１３により止着された合成樹脂製の取付支持台１４の取付凸部１４ａに対しその取付凹部９ｂを嵌め合わせて取付けられている。
【００１３】
１５は上臼で、その粉砕面１５ａが上記下臼８の粉砕面８ｂに合致し、その上端部１５ｂを上記下臼８の上端部８ｅと略同一の長さに形成されている。該上臼１５は上記の下臼８と同じセラミックス製である。また、該上臼１５の外面（下面）１５ｃ側には上記粉砕面１５ａが形成されていると共に内面（上面）１５ｅ側に位置してホッパ−部１５ｄが形成されている。
【００１４】
ホッパ−部１５ｄは、上部の材料投入口端１５ｍ側から下部の材料排出口１５ｆ側に向かって狭められた漏斗形状になっていて下部の材料排出口１５ｆは外面（下面）側の粉砕面１５ａ側と連通している。１５ｇは下部の中央に位置して形成した貫通孔であり、同孔１５ｇには軸穴１６ａを形成した合成樹脂製の穴部材１６が嵌合接着されている。
【００１５】
上記粉砕面１５ａは上記下臼８の粉砕面８ｂと対向した外面（下面）１５ｃ側に形成され、該粉砕面１５ａには上記下臼８の場合と同様に主溝１５ｈと副溝１５ｉが全周にわたり交互に形成されている。さらに上臼１５の粉砕面１５ａ側には、図４に示すように、臼体の回転方向に合わせて材料排出口１５ｆの下端から粉砕面１５ａに至るように形成した円弧状の材料用ガイド溝１５ｎが形成されている。なお、上記上臼１５と下臼８は、各種実験の結果、その中心角度（開口角度）が６０度〜９０度程度のものが特に使用に適しており、本願実施例の例えば図１乃至図５のものは９０度のものが使用されている。
【００１６】
１７は上臼１５のホッパ−部１５ｄの材料投入口端１５ｍ側を塞ぐようにしてその外周面に形成した取付溝１５ｋに対し取り外し自在に嵌着したポリエチレンやポリプロピレン等の合成樹脂製の内蓋であり、透明或いは半透明材で形成されている。該内蓋１７は臼を傾斜させて粉砕機１を作動させた場合にホッパ−部１５ｄ内の粉砕未処理物（例えば、葉茶ａ）が材料投入口端１５ｍ側から臼外へこぼれ落ちないようにするものである。また同蓋１７の上面中央には上蓋ケ−ス６の材料投入口６ａに連接するようにして材料補給穴１７ａが形成されている。
１７ｂは刷毛状の掃き出し部材であり、上記内蓋１７を上臼１５に嵌着した際に同部材１７ｂが受け皿部３ａ上の滞積した粉末処理物（粉末茶ｂ）を掃き出しできるように設けられており、同部材１７ｂは本実施例では内蓋１７と一体成形され、また内蓋１７の外周面の２カ所に適宜間隔で設けられている。
【００１７】
６は上蓋ケースで、下端５ｂを下部ケ−ス４の上端４ｂ側に嵌着してなる中間部ケ−ス５に対し開閉自在に軸着されており、上蓋ケース６側に設けたピン１８を中間部ケ−ス５側のヒンジ溝５ｃに係合して上蓋ケ−ス６を開閉自在に軸着してなる軸着部と、同部に対向して反対側の位置に設けた上蓋ケ−ス６側のフック１９とフック用のバネ２０と中間部ケ−ス５側に設けたフック用突起５ｄ等からなる止着部とが設けられている。なお、上蓋ケース６を開蓋する場合は、止着部の押圧部材４１をバネ２０に抗して内側に押さえれば上蓋ケース６側のフック１９が中間部ケ−ス５側のフック用突起５ｄから外れて開蓋できるようになっている。
【００１８】
２１は撹拌部材で上臼５のホッパ−部１５ｄ、特に下部に位置する材料排出口１５ｆ付近でブリッジ状に絡み合って停滞する粉砕未処理物（例えば葉茶ａ）を上臼１５の回転に伴ってその都度撹拌するように備えられており、更に同部材２１は上蓋ケ−ス６の中央に位置する材料投入口６ａに付設した保持部６ｄに対し外（上方）側から挿入装着されており、下方の先端部２１ａが上臼１５の下部の材料排出口１５ｆ上にあるように配置されている。
２１ｂは撹拌部材２１を保持部６ｄに装着保持するための保持用鍔を示す。なお、撹拌部材２１は先細状に形成され、保持部６ｄに保持された撹拌部材２１を上方に抜き取ることにより交換が可能であり、例えば切損したりした場合は新しいものに交換することが可能である。
２２は材料投入口６ａに対し上方側から取脱自在に装着するようにした透明或いは半透明またはケ−スと同色の合成樹脂製の栓体を示す。
【００１９】
また、３は上部ケースで、上蓋ケ−ス６によりその外側が覆うわれるとともに上臼１５及び下臼８を収納するようにしたもので、中間部ケ−ス５の上端側の受け部５ａ上に載置されていて上蓋ケ−ス６の開蓋時、上、下臼１５、８の取り外し後に同ケ−スの取り外しができるようになっている。３ｃは下臼８と上臼１５の接合端面イから排出された粉末処理物（例えば、粉末茶ｂ）を機外へ排出するための注ぎ口状の掃き出し口であり、上臼１５と下臼８との接合端面イから排出されて受け皿部３ａ上に落下及び滞積した粉末処理物（粉末茶ｂ）を上臼１５の回転に伴って回転する内蓋１７の掃き出し部材１７ｂにより掃き出し口３ｃ方向に掃き集め、同口３ｃより機外に排出させるようになっている。なお、掃き出し口３ｃは受け皿部３ａに連接して設けられている。
【００２０】
２３は上蓋ケ−ス６の内面側に付設した上部補助ケ−スであり、上部ケ−ス３の上端開口部３ｄを内蓋１７のさらに上方から閉鎖するようにして設けられるもので、中央に形成した補助穴２３ａに止着した装着部材２４を介して上蓋ケ−ス６の材料投入口６ａの周囲の内方突出部６ｅに嵌合止着されている。なお、上蓋ケ−ス６の内方突出部６ｅの下端６ｆは内蓋１７の材料補給穴１７ａの周囲の上方突起１７ｃ内の受け部１７ｄに当接している。
【００２１】
また４は回転駆動装置２５等を収納するための下部ケ−スであり、同ケ−ス４内には交流駆動用の小型モ−タ−２６と、小型モ−タ−２６の回転を低速に変速するための変速ギヤ−２７が合体された状態で収納されている。２８はモ−タ−２６とギヤ−２７を合体するためのネジ部材を示す。
【００２２】
２９は回転駆動装置２５を中間部ケ−ス５の取付部５ａ上の取付用のベ−ス金具１２に、その下面１２ｃ側に位置して吊り下げ状に止着するための取付金具であり、該取付金具２９は３組ギヤ−ケ−ス３０に一体的に固設され（１組は図示されていない）、各金具２９をネジ３１によってベース金具１２に止着している。
なお、取付に際し、回転駆動装置２５の出力軸となる回転軸３２はベ−ス金具１２の軸穴１２ｄ、支持部材１４の軸穴１４ｂ、下臼８の穴部材１１の軸穴１１ａ、上臼１５の穴部材１６の軸穴１６ｂを貫通し、最上部に位置する上記上臼１５の軸穴１６ｂから先端のネジ部３２ａが上方に突出した状態で取り付けられるもので、突出した先端のネジ部３２ａに対しさらに外面が円弧状の丸みを持った袋ナット３３を上方よりネジ着して上臼１５並びに下臼８を回転軸３２に取り付けるようにしている。
なお、この上、下臼１５，８の回転軸３２への取付により、上臼１５のみが回転することになる。つまり、下臼８側はその穴部材１１の軸穴１１ａが丸穴になっていて回転軸３２と無関係で一体に回転することはないが、上臼１５側は穴部材１６の軸穴１６ａが小判形になっていてこれが回転軸３２の小判形状部分３２ｂに嵌合しているため回転軸３２と一体に回転するようになっている。
【００２３】
１４はベ−ス金具１２上にビス１３によりネジ着した合成樹脂製の支持部材であり、同部材１４のその取付凸部１４ａに対し上記下臼８の取付補助台９の取付凹部９ｂを嵌め合せて上臼１５の回転駆動時に下臼８が不用意に回転しないようにしている。９ｄは支持部材１４に形成したバネ収納部であり、同部９ｄにはコイルバネ３４と上下方向に進退自在なピストン状の押圧部材３５が収納されており、押圧部材３５の先端３５ａが補助取付台９の下面の受け止め部９ｅに当接して同台９と一体の下臼８を上記コイルバネ１５のバネ力により上臼１５側に押圧するようにしている。なお、このバネ力の強弱を調節すると上臼１５と下臼８の粉砕面の粉砕圧力が任意に変化し、処理物の粉砕粒度の調節が行えるようになっている。
【００２４】
図６乃至図９において、３６は吊り下げ用の持ち手で、本体ケ−スの中間部ケ−ス５の補強部５ｅに一体形成したガイド部５ｆに持ち手３６に形成した取付穴３６ａを嵌合して備えられており、更に持ち手３６は本体ケ−ス１側に付設した滑り止め部材３７と協働して角度変更装置３８をも構成している。つまり、粉砕機１は処理物の粉砕粒度を調節するために、例えば図９にあるように掃き出し口３ｃ側に約３０度傾斜させて運転する。
即ち、持ち手３６を任意の角度（例えば図９において角度θを略３０度）に設定した状態で、ネジ具４４の握り部４４ａを締め付け方向に回すとネジ部４４ｂが中間部ケ−ス５側の補強部５ｅのネジ孔５ｇにネジ着して持ち手３６は、図７に示すように握り部４４ａの内面４４ｃと補強部５ｅの当接部５ｅ′間で締め付け固定された状態になり、その角度で回動が拘束される。そして持ち手３６を拘束した状態で図９のように設置面３９に傾斜設置すれば粉砕機１の傾斜運転が可能になる。なお通常、ネジ具４４は締め付けを緩めた状態にあり、何ら拘束を受けるがないため持ち手３６は補強部５ｅのガイド部５ｆを中心に自在に回動し、通常の持ち手の機能になる。
【００２５】
４５はワッシャ−、４６は抜け止め用の割りピンを示す。
３７は角度調整装置のもう一方を構成する本体ケ−ス２側に付設したゴム或いは柔軟性のある合成樹脂等からなる滑り止め部材であり、底蓋ケ−ス７の底部外周面における掃き出し口３ｃ側に位置してけ強固に止着されている。
【００２６】
また、７は底蓋ケ−スであり、下部ケ−ス４の下端開口部４ａを閉鎖するためのもので、中央には回転駆動装置２５からの運転時の発熱を本体ケ−ス外へ放熱するための空気穴７ｃが形成されている。
４０は底蓋ケ−ス７、下部ケ−ス４、中間部ケ−ス５を一体連結するための連結用ネジであり、底蓋ケ−ス７側の取付穴７ａより同ネジを差し込み、その先端のネジ部４０ａを中間部ケ−ス５の受け止め部５ａ上のベ−ス金具１２のネジ部１２ｆにネジ着するようにしたもので、上記の連結は上記連結用ネジ３本（２本は図示されていない）で行われている。
４２は電源スイッチ兼用のタイマ−であり、粉砕機の回転（運転）時間を任意に設定するためのもので、目的の粉砕粒度等に合わせて時間長さが設定される。
【００２７】
次に上記粉砕機１の使用し葉茶ａを粉末茶ｂにする場合について説明する。
粉砕機１の停止状態において、上蓋ケ−ス６の栓体２２を外し、同ケ−ス２２の材料投入口６ａより葉茶ａを上臼１５のホッパ−部１５ｄ内に所定量投入供給する。
そして、図示外の電源コ−ドをコンセントに差し込み、電源（タイマ−４２）をオンにすると回転駆動装置２５が始動し、回転軸３２が低速度で回転する。この回転により上臼１５が回転し、投入された葉茶ａも回転し、上蓋ケ−ス６に固定的に付設した撹拌部材２１の存在により、投入された葉茶ａが撹拌される。そのため葉茶ａはホッパー部１５内でブリッジ状に組み合うことが防止され上臼１５の下部の材料排出口１５ｆよりスム−ズに排出される。
また、同口１５ｆより排出された葉茶は上臼１５の回転に伴う遠心力により材料用ガイド溝１５ｎを経て粉砕面１５ａに誘導される。葉茶ａはさらに上臼１５の回転により上下両臼１５、８の主溝１５ｈ、８ｈ並びに副溝１５ｉ、８ｊの交差及び摺動により粉砕あるいは擂り潰されながら溝内または溝上を移動し、放射方向である外周側に向かって移動する。この場合、上下両臼の粉砕面１５ａ、８ｂが摺鉢状であるため、葉茶ａは粉砕面を行ったり来りして長く滞留し、そして徐々に外周側へ向かって移動しながらより微細に粉砕されていく。
なお、粉砕作業を連続して行う場合は材料の減り具合を栓体２１越しに或いは上蓋ケ−ス６を開蓋した状態で、見ながらホッパ−部１５ｄ内に葉茶ａを供給するようにする。
【００２８】
粉砕が進むと、上臼１５と下臼８の接合端面イより粉砕された粉末茶ｂが排出され、それが受け皿部３ａ上に落下する。落下した粉末茶ｂは、上臼１５と共に回転する内蓋１７に設けられた掃き出し部材１７ｂの回転移動による掃き出し作用により掃き出し口３ｃ方向に掃き出しされて移動し、受け皿部３ａに連接して設けた掃き出し口３ｃから機外へ排出される。排出された粉末茶ｂは掃き出し口３ｃに位置して別設置されたコップ等の容器内に落下し溜められる。
【００２９】
なお、本願発明の粉砕機は、任意の角度、例えば水平状態から４５度の範囲の傾斜角度で使用することにより粉末茶等の粒度を調節することが可能である。つまり図９のように傾斜させた状態で駆動すると、葉茶の粉砕面に滞在する時間（粉砕工程の時間）がそれに伴って短くなり、図１のように水平状態で粉砕する場合に比べて粒度の粗いものができる。
【００３０】
次に本粉砕機１の使用後の手入れにつて説明する。
本願発明の粉砕機は上蓋ケ−ス６、内部ケ−ス３が分解可能で掃除がしやすくなっている。
まず、上蓋ケ−ス６を開蓋する。必要により本体ケ−ス側の軸着部より上蓋ケ−ス６を外す。次に袋ナット３３を緩めて外し、上臼１５を持ち上げて回転軸３２から外す。下臼８も同様に持ち上げて外し、そして両臼の取り外しが終わったならば内部ケ−ス３を外す。上下両臼、内部ケ−スは刷毛さらには必要により水洗いして付着した粉末残物を取り除き、空拭き、乾燥する。また本体ケ−ス１側も刷毛等で清掃する。上記の如く清掃が済んで一旦取り外した上臼等は取り外しとは逆の手順で本体ケ−スに再組み付けて、掃除が完了する。なお、使用後の清掃（手入れ）はその都度行う必要はなく付着状況等を見て必要により行う。
【００３１】
【発明の効果】
請求項１記載の発明によれば、上蓋ケ−スに撹拌部材を付設し、この撹拌部材により上臼のホッパ−部内の未処理物（葉茶ａ）を上臼の回転に伴って撹拌するようにしたため、ホッパ−部に投入された未処理物はブリッジ状に絡まることなく上臼の下部の材料排出口より粉砕面にスム−ズに排出されことになり、粉砕作業が一段と効率的に行えるようになる。
【００３２】
請求項２記載の発明によれば、粉砕面で微粉末に粉砕された処理物、例えば粉末茶ｂは上下両臼の接合端面から受け皿部に排出（落下）するが、この排出された粉末が受け皿部に滞積した場合にも、上臼に取着して上臼の回転に伴って一緒に回転する内蓋の掃き出し部材により掃き出し口へ向かって強制的に掃き出されるようにしたため、請求項１の効果に加え処理物の機外への排出が効率的に行えるようになる。
【００３３】
更に、前記請求項１又は２の発明においては、傾斜状態で粉砕機を駆動して処理物の粉砕粒度を調節する角度変更装置を、所定の角度に固定（拘束）できる持ち手と本体ケ−スの下部に設けた滑り止め部材とで構成したため、従来の角度変更装置に比べて簡単な構造でコストを低減することができた。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a crusher for crushing cereals such as sesame, wheat, buckwheat and the like into powder having an appropriate particle size (fineness) in addition to tea.
[0002]
[Prior art]
Tea is not only a favorite but also popular as a health food. Tea contains abundant vitamins and minerals, and if the tea is simply put out with hot water, most of the above nutrients remain in the tea and the nutrients cannot be consumed. Therefore, if the leaf tea is made into powdered tea and served with hot water, sufficient intake of the above nutrients becomes possible.
By the way, as a pulverizer for converting leaf tea into powdered tea, a mortar having a flat pulverized surface is generally used.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned stone mill, since the crushed surfaces of the upper mill and the lower mill facing each other are flat, the residence time on the crushed surface is shortened, and powder tea with an appropriate particle size may not be obtained. As a solution to this, it is conceivable to lengthen the grinding process by using a large diameter in order to increase the residence time on the grinding surface of the mortar. It is not preferable because a large power is required.
[0004]
In order to solve the above problems, the present inventor previously provided a technique as shown in FIG. 10 according to Japanese Patent Application No. 6-272819. This technology is hereinafter referred to as the prior application technology.
The pulverizer shown in FIG. 10 includes a ceramic lower mortar 101 having a mortar-shaped pulverized surface 101b on the inner surface 101a side, and a pulverized surface 102b formed on the outer surface 102a side. A new small (table) type comprising a ceramic upper mortar 102 having a matching funnel-shaped hopper portion 102d on the inner surface 102c side and a driving device 103 for rotationally driving the upper mortar 102. Crusher.
[0005]
The pulverizer of the above prior application is superior to the conventional stone mill type in that it is small and simple in structure and easy to handle. For example, depending on the type of leaf tea a a is entangled in a bridge shape in the hopper portion 102d of the upper die, and leaf tea (material) stagnates near the material discharge port 102e provided in the lower portion of the upper die 102 and moves (supply) to the grinding surface side. May not be able to be performed smoothly.
[0006]
The pulverizer of the above prior application is a method in which the powdered tea crushed on the pulverized surface is discharged from the discharge port of the joint end face A of the upper mortar 102 and the lower mortar 101. It may fall on the saucer (part) 104 and accumulate, and may not be smoothly guided to the discharge port.
[0007]
In addition, for the purpose of adjusting the pulverization particle size, the pulverizer of the prior application is provided with an angle changing device 105 to incline (drive) the mortar, but the angle changing device has a complicated structure. Therefore, it is a factor of high cost.
[0008]
[Means for Solving the Problems]
