Description

【０００１】
【発明の属する技術分野】
本発明は、各種食品のかやくや添加物として用いられる揚げ玉を自動的に製造することができる揚げ玉製造方法及び装置に関する。
【０００２】
【従来の技術】
従来、テンプラを揚げた後にできるテンプラ滓は、そのまま捨てるのはもったいないので、うどん、そば、お好み焼き等の加薬として用いられている。しかし、近年、加薬としての用途はうどんやそば等のみならず、多種多用な加工食品に用いられており、例えば、その一例としてパン粉の代替品としての使用をあげることができる。
しかし、テンプラを揚げた際の副産物としてのテンプラ滓の量はきわめて限られたものであるため、近年、小麦粉から揚げ玉のみを製造することができる図８に示すような揚げ玉製造装置Ｂが開発されている。
【０００３】
図示するように、上面が開口した長尺箱状の油槽８０内には加熱油８１が貯えられている。油槽８０の上流側の上方には、粘稠質の揚げ玉原料８２を油槽８０内の加熱油８１中に粒状に連続して落下して供給する原料供給機構８３が配設されている。そして、油槽８０の下流側端部に設けた加熱油取り出し口８４より加熱油８１を取り出し、加熱油８１を油槽８０の上流側端部に設けた加熱油流出口８５から油槽８０中に流出する加熱油循環路８６が設けられている。また、油槽８０の上方には、加熱油８１中に揚げ玉原料８２を落下することによって製造され加熱油８１表面に浮遊する揚げ玉８７を、上流側から下流側に向けて移送する掻き板８８ａ付きのチェンコンベア８８ｂからなる揚げ玉移送機構８８が配設されている。
なお、図示の揚げ玉製造装置Ｂにおいて、８９は揚げ玉回収箱、９０は油槽８０を加熱する加熱手段、９１は加熱油循環路８６に設けた循環ポンプである。
【０００４】
上記した構成によって、加熱手段９０によって油槽８０中の加熱油８１を所定の温度まで加熱すると共に、加熱油循環路８６に設けた循環ポンプ９１を駆動して、油槽８０から加熱油取り出し口８４を通して加熱油８１を取り出すと共に、加熱油流出口８５を通して油槽８０中に加熱油８１を流出し、油槽８０内の加熱油８１を上流側から下流側にゆるやかな速度で流す。また、揚げ玉移送機構８８を駆動してチェンコンベア８８ｂを回転し、掻き板８８ａを加熱油８１の表面に沿って上流側から下流側に移動する。
その後、原料供給機構８３から粘稠質の揚げ玉原料８２を油槽８０内の加熱油８１中に粒状に連続して落下して供給すると、揚げ玉原料８２の表面張力で球状になった後、加熱油８１によって揚げられ、球状の揚げ玉８７を製造することができる。このような揚げ玉８７は、いったん油面より相当深さ沈んだ後、比重が油より軽いので、徐々に浮き上がり、加熱油８１の表面に浮遊することになる。その後、揚げ玉移送機構８８の掻き板８８ａによって油槽８０内を上流側から下流側に向けて移送され、油槽８０の下流側に設けた排出口より排出され、揚げ玉回収箱８９内に回収される。
このように、揚げ玉製造装置Ｂを用いることによって、揚げ玉８７を大量製造することができる。
【０００５】
【発明が解決しようとする課題】
しかし、上記した構成を有する揚げ玉製造装置Ｂは、未だ、以下の解決すべき課題を有していた。
即ち、図８に示すように、加熱油循環路８６に設けた循環ポンプ９１を駆動して、加熱油流出口８５を通して油槽８０中に流出した加熱油８１の流れは乱流となって上方に移動した後、下流側に向かって流れることになる。従って、原料供給機構８３から粒状に連続して加熱油８１中に供給される揚げ玉原料８２は、乱流状態の加熱油８１中に落下することになるが、乱流状態では、加熱油８１の流れが乱れているのみならず、表面に沿ってのみしか加熱油８１は上流側から下流側に向けて流れないため、図８に示すように、加熱油８１中で複雑な動きをしながら加熱油８１の表面に浮遊することになる。その結果、揚げ玉８７同士が干渉したり衝突し、一部がひっついたり、一体化して、大きさ及び形状の異なる揚げ玉８７が製造されることになり、揚げ玉８７の商品価値を著しく低下させることになる。
【０００６】
本発明は、このような事情に鑑みなされたものであり、均一の形状及び均一の粒径を有し、商品価値を著しく高めることができる揚げ玉を大量製造することができる揚げ玉製造方法及び装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
前記目的に沿う本発明に係る揚げ玉製造方法は、多数の小孔からなる揚げ玉原料流出ノズルから粘稠質の揚げ玉原料を、該揚げ玉原料の表面張力で球状化して加熱油中に連続して落下し、前記揚げ玉原料が前記加熱油中に供給される個所における該加熱油の流れを、前記揚げ玉原料が落下する位置の上流側の加熱油中に設けられた整流発生機構を介して、該加熱油の表面から前記揚げ玉原料が該加熱油中を落下する位置まで上流側から下流側に向けて層流とし、前記加熱油中に落下した前記揚げ玉原料を下流側に流しながら加熱し浮き上がらせて均一な形状と均一な粒径の揚げ玉を製造する。
この場合、整流が上層部のみならず下層部でも確保されているので、揚げ玉原料が落下する深さ（例えば、加熱油の表面から１５０ｍｍ）の全長にわたって加熱油の均一な流れ（整流された流れ）を確保できる。従って、いったん加熱油の下層部まで落下した揚げ玉原料は、その後、一定距離、下流側に向けて水平移動した後に、揚げ玉となって、徐々に上り勾配で加熱油の表面まで放物線を描きながら浮遊することになる。従って、粒状の揚げ玉原料は、それぞれが独立した球体の状態で十分に揚げられ均一な形状と均一な粒径を有する揚げ玉を製造することができ、揚げ玉の商品価値を高めることができる。なお、揚げ玉の形状は、粒状の揚げ玉原料の粘稠度、落下速度等を調整することによって球状以外の形状、例えば、傘状、円盤状とすることもできる。
本発明に係る揚げ玉製造装置は、上面が開口し内部に加熱油を貯えた長尺の油槽と、
前記油槽の上流側の上方に配設され、粘稠質の揚げ玉原料を表面張力で球状化して前記油槽内の加熱油中に連続して落下して供給する原料供給機構と、
前記油槽の下流側端部に設けた加熱油取り出し口より前記加熱油を取り出し、循環ポンプを介して前記加熱油を前記油槽の上流側端部に設けた加熱油流出口から前記油槽中に流出する加熱油循環路と、
前記加熱油中にあって、前記揚げ玉原料が落下する個所の上流側に配設され、前記揚げ玉原料が前記加熱油中を落下する深さまでの前記加熱油の流れを層流とする整流発生機構と、
前記油槽の上方に配設され、前記加熱油中に前記揚げ玉原料を落下することによって製造され前記加熱油表面に浮遊する揚げ玉を、上流側から下流側に向けて移送する揚げ玉移送機構とを具備する揚げ玉製造装置であって、
前記整流発生機構は、前記油槽の底部に設けられ前記加熱油を上方に向けて流出する前記加熱油流出口の上方に上、下に間隔をあけて重合状態に配設され、基部がそれぞれ該加熱油流出口の上流側周縁部に接続されると共に、先部が弧を描きながら前部上方に向けて延びる第１、第２の加熱油案内板を具備し、該第２の加熱油案内板の基部に連絡開口を設け、前記第１、第２の加熱油案内板の間に該連絡開口を通して前記加熱油流出口からの加熱油が弧状に流れる上部整流形成流路を形成すると共に、前記第２の加熱油案内板の下面に下部整流形成流路を形成した。
【０００８】
この場合、原料供給機構から粒状に連続して整流（層流）状態の加熱油中に落下することができ、しかも、整流が上層部のみならず下層部でも確保されているので、それぞれが独立した球体の状態で十分に揚げられ均一な形状と均一な粒径を有する商品価値の高い揚げ玉を大量生産することができる。
【０００９】
上記構成を有する揚げ玉製造装置において、整流発生機構は、油槽の底部に設けられ加熱油を上方に向けて流出する加熱油流出口の上方に上、下に間隔をあけて重合状態に配設され、基部がそれぞれ加熱油流出口の上流側周縁部に接続されると共に、先部が弧を描きながら前部上方に向けて延びる第１、第２の加熱油案内板を具備し、第２の加熱油案内板の基部に連絡開口を設け、第１、第２の加熱油案内板の間に連絡開口を通して加熱油流出口からの加熱油が弧状に流れる上部整流形成流路を形成すると共に、第２の加熱油案内板の下面に下部整流形成流路を形成しているので、簡易な構造で、粒状の揚げ玉原料が落下してくる加熱油の個所において、上層部のみならず下層部にも容易かつ確実に整流を形成することができ、均一な形状及び均一な粒径を有する商品価値の高い揚げ玉を製造することができる。
【００１０】
さらに、揚げ玉原料が落下する個所と、揚げ玉移送機構の上流側端との間に、浮上した揚げ玉を下流側へ押しやる揚げ玉滞留防止機構を配設することもできる。この場合、加熱油の表面に浮上した揚げ玉原料が浮上個所に滞留するのを防止することができるので、揚げ玉製造装置のライン速度を高めることができ、揚げ玉をより確実に大量に製造することができる。
【００１１】
【発明の実施の形態】
続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
まず、図１及び図２を参照して、本発明の一実施の形態に係る揚げ玉製造装置Ａの全体構成を説明する。
図示するように、上面が開口した長尺箱状の油槽１０内には加熱油１１が貯えられている。油槽１０の上流側の上方には、粘稠質の揚げ玉原料１２を油槽１０内の加熱油１１中に粒状に連続して落下して供給する原料供給機構１３が配設されている。
油槽１０の下流側端部に設けた加熱油取り出し口１４より加熱油１１を取り出し、加熱油１１を油槽１０の上流側端部に設けた加熱油流出口１５から油槽１０中に流出する加熱油循環路１６が設けられており、加熱油循環路１６の中途部分には循環ポンプ１７が取付けられている。
【００１２】
油槽１０の上方には、加熱油１１中に揚げ玉原料１２を落下することによって製造され加熱油１１表面に浮遊する揚げ玉１８を、上流側から下流側に向けて移送する掻き板１９付きのチェンコンベア２０からなる揚げ玉移送機構２１が配設されている。
加熱油１１中において揚げ玉原料１２が落下する個所の上流側には、加熱油１１の表面から揚げ玉原料１２が落下する深さ（最落下位置）までの加熱油１１の流れを、上流側から下流側に向けて層状に流れる整流にする整流発生機構２２が配設されている。
油槽１０の下方には、油槽１０を加熱する加熱手段の一例である複数のバーナー２３が配設されている。なお、バーナー２３に変えて電熱ヒーターを用いることもできる。
油槽１０の下流側端部には揚げ玉製造装置Ａによって製造された揚げ玉１８を回収する揚げ玉回収箱２４が連設されている。
【００１３】
次に、上記した構成を有する揚げ玉製造装置Ａの各部の構成について、図１〜図４を参照して詳細に説明する。
図１に示すように、長尺の油槽１０の上流側は、原料供給機構１３から粒状の揚げ玉原料１２が落下してくる個所を含めて、落下してくる揚げ玉原料１２を加熱油１１中に十分な深さ浸漬することができるように深底となっている。一方、油槽１０の下流側は、表面に揚げ玉１８を浮遊させるに十分な深さを有すればよいので浅底となっており、また、深底部２５と浅底部２６の中間には、その内面に沿って揚げ玉１８を円滑に浮き上がらせるための傾斜部２７が形成されている。また、深底部２５の上流側端には、幅方向に間隔をあけて一対の加熱油流出口１５が設けられている。
【００１４】
図１及び図２に示すように、原料供給機構１３は、粘稠質のメリケン粉を攪拌しながら貯留すると共に下方に定量的に切り出すことができるホッパー２８と、ホッパー２８の下部に配設されると共に、下面に多数の小孔からなる揚げ玉原料流出ノズル２９を具備する横長パン３０とから構成されている。そして、この揚げ玉原料流出ノズル２９を通して、加熱油１１中に、粒状の揚げ玉原料１２を連続的に落下して供給することができる。
【００１５】
図１及び図２に示す揚げ玉移送機構２１において、チェンコンベア２０は、油槽１０の上方において、幅方向に平行間隔をあけて配設した一対の無端チェン３１から構成されており、無端チェン３１間には、アタッチメントを介して、多数の掻き板１９が、長手方向に所定ピッチで架設されている。なお、図示するように、各掻き板１９は横長の矩形板からなり、その両端は、油槽１０の両側壁の内面に略当接する位置に配置されている。また、チェンコンベア２０は、下流側スプロケット３２を固着した回転軸３３に連動連結された回転モータ３４によって回転駆動される。
【００１６】
図１〜図４に示す整流発生機構２２において、油槽１０の深底部２５に設けられ加熱油１１を上方に向けて流出する加熱油流出口１５の上方には、上、下に間隔をあけて第１、第２の加熱油案内板３５、３６が重合状態に配設されている。第１、第２の加熱油案内板３５、３６の基部はそれぞれ加熱油流出口１５の上流側周縁部に接続されると共に、先部は弧を描きながら前部上方に向けて延びている。また、第２の加熱油案内板３６の基部には横長矩形形状の連絡開口３７が設けられている。
従って、第１、第２の加熱油案内板３５、３６の間に連絡開口３７を通して加熱油流出口１５からの加熱油１１が弧状に流れる上部整流形成流路３８を形成することができると共に、第２の加熱油案内板３６の下面に下部整流形成流路３９を形成することができる。
【００１７】
次に、上記した構成を有する揚げ玉製造装置Ａを用いて揚げ玉１８を製造する揚げ玉製造方法について説明する。
まず、バーナー２３によって油槽１０中の加熱油１１を所定の温度（例えば、１７０°〜２００°）まで加熱すると共に、加熱油循環路１６に設けた循環ポンプ１７を駆動して、油槽１０から加熱油取り出し口１４を通して加熱油１１を取り出すと共に、加熱油流出口１５を通して油槽１０中に加熱油１１を流出し、油槽１０内の加熱油１１を上流側から下流側にゆるやかな速度で流す。また、揚げ玉移送機構２１を駆動してチェンコンベア２０を回転し、掻き板１９を加熱油１１の表面に沿って上流側から下流側に移動する。
【００１８】
その後、原料供給機構１３から粘稠質の揚げ玉原料１２を油槽１０内の加熱油１１中に粒状に連続して落下して供給すると、揚げ玉原料１２の表面張力で球状になった後、加熱油１１によって揚げられ、球状の揚げ玉１８を製造することができる。このような揚げ玉１８は、いったん油面より相当深さ沈んだ後、比重が油より軽いので、徐々に浮き上がり、加熱油１１の表面に浮遊することになる。その後、揚げ玉移送機構２１の掻き板１９によって油槽１０内を上流側から下流側に向けて移送され、油槽１０の下流側に設けた排出口４０より排出され、揚げ玉回収箱２４内に回収される。
このように、揚げ玉製造装置Ａを用いることによって、揚げ玉１８を大量製造することができる。
【００１９】
また、本実施の形態では、第１、第２の加熱油案内板３５、３６の間に加熱油１１が弧状に流れる上部整流形成流路３８と、第２の加熱油案内板３６の下面に下部整流形成流路３９を形成したので、原料供給機構１３から粒状に連続して加熱油１１中に供給される揚げ玉原料１２を、整流状態の加熱油１１中に落下することにできる。しかも、整流が上層部のみならず下層部でも確保されているので、揚げ玉原料１２が落下する深さの全長にわたって加熱油１１の均一な流れを確保できる。従って、いったん加熱油１１の下層部まで落下した揚げ玉原料１２は、その後、一定距離、下流側に向けて水平移動した後に徐々に上り勾配で加熱油１１の表面まで浮遊することになる。即ち、揚げ玉原料１２の落下と同時に上層部で熱交換が始まり水分の蒸発が進みながら下層部に向けて沈むにつれて、徐々に浮力がつき下層部の最落下位置で浮力が最大になると共に落下エネルギーがなくなる。その後、揚げ玉１８は下層部における流れによって放物線を描きながら加熱油１１の表面に浮遊することになる。その結果、それぞれが独立した球体の状態で十分に揚げられ均一な形状と均一な粒径を有する揚げ玉１８を製造することができ、揚げ玉１８の商品価値を高めることができる。
【００２０】
図５に上記した揚げ玉製造装置Ａの変形例に係る揚げ玉製造装置Ａ１を示す。図示するように、揚げ玉製造装置Ａ１は、以下の構成を除いて、実質的に揚げ玉製造装置Ａと同一の構成を有するので、同一の構成要素は同一の符号で示す。
図示するように、本変形例は、揚げ玉原料１２が落下する油槽１０内の個所と、揚げ玉移送機構２１の上流側端との間に、加熱油１１に上流側から下流側への流動エネルギーを付与して浮上した揚げ玉１８を下流側へ押しやる揚げ玉滞留防止機構の一例である回転パドル４１を配設したことを特徴とする。
このような構成とすることによって、粒状の揚げ玉原料１２をさらに積極的に分離させて独立した球体の状態で十分に揚げ、さらに均一な形状と均一な粒径を有する揚げ玉１８を製造することができ、揚げ玉１８の商品価値をさらに高めることができる。また、揚げ玉製造装置Ａ１のライン速度を高めることができるので、より大量に製造することができる。
【００２１】
図６及び図７に上記した揚げ玉製造装置Ａの変形例に係る揚げ玉製造装置Ａ２を示す。図示するように、揚げ玉製造装置Ａ２は、揚げ玉製造装置Ａの整流発生機構２２に相当する整流発生機構４２を、揚げ玉原料１２が落下する個所の上流側に内部を縦仕切板４３と横仕切板４４で仕切られた長手方向に延びる案内筒４５から構成し、案内筒４５の内部に上、下部整流形成流路４６、４７を設けたことを特徴とする。
この場合も、簡易な構造で、粒状の揚げ玉原料１２が落下してくる加熱油１１の個所において、上層部のみならず下層部にも容易かつ確実に整流を形成することができるので、粒状の揚げ玉原料１２は、それぞれが独立した球体の状態で十分に揚げられ均一な形状と均一な粒径を有する揚げ玉１８を製造することができ、揚げ玉１８の商品価値を高めることができる。
【００２２】
以上、本発明を、一実施の形態を参照して説明してきたが、本発明は何ら上記した実施の形態に記載の構成に限定されるものではなく、特許請求の範囲に記載されている事項の範囲内で考えられるその他の実施の形態や変形例も含むものである。
【００２３】
【発明の効果】
請求項１記載の揚げ玉製造方法においては、加熱油中において揚げ玉原料が落下する個所の上流側に、揚げ玉原料が落下する深さまでの加熱油の流れを、上流側から下流側に向けて層状に流れる整流にし、この整流に粒状の揚げ玉原料を連続して加熱油中に落下することができ、しかも、整流が上層部のみならず下層部でも確保されているので、揚げ玉原料が落下する深さの全長にわたって加熱油の均一な流れを確保できる。従って、いったん加熱油の下層部まで落下した揚げ玉原料は前方に向けて放物線を描きながら揚げ玉となって加熱油の表面まで浮遊することになり、均一な形状と均一な粒径を有する揚げ玉を製造することができ、揚げ玉の商品価値を高めることができる。

【００２５】
そして、整流発生機構を、加熱油流出口の上方に上、下に間隔をあけて設けた第１、第２の加熱油案内板によって加熱油流出口からの加熱油が弧状に流れる上部整流形成流路を形成すると共に、第２の加熱油案内板の下面に下部整流形成流路を形成したので、粒状の揚げ玉原料が落下してくる加熱油の個所において、上層部のみならず下層部にも容易かつ確実に整流を形成することができ、均一な形状及び均一な粒径を有する商品価値の高い揚げ玉を製造することができる。
【００２６】
請求項３記載の揚げ玉製造装置においては、揚げ玉原料が落下する個所と、揚げ玉移送機構の上流側端との間に揚げ玉滞留防止機構を配設したので、加熱油の表面に浮上した揚げ玉が浮上個所に滞留するのを防止することができ、揚げ玉製造装置のライン速度を高めることができ、揚げ玉をより確実に大量に製造することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a fried ball manufacturing method and apparatus capable of automatically manufacturing fried balls used as a kaya or additive for various foods.
[0002]
[Prior art]
Conventionally, tempura rice cake made after fried tempura is wasteful to throw away as it is, so it has been used as an additive for udon, soba, okonomiyaki, etc. However, in recent years, the use as a medicine has been used not only for udon and soba, but also for various processed foods. For example, it can be used as a substitute for bread crumbs.
However, since the amount of tempura koji as a by-product when tempura is fried is very limited, in recent years, a fried ball manufacturing apparatus B as shown in FIG. 8 capable of producing only fried balls from flour has been developed. ing.
[0003]
As shown in the figure, heating oil 81 is stored in a long box-shaped oil tank 80 whose upper surface is open. Above the upstream side of the oil tank 80, a raw material supply mechanism 83 is provided in which a viscous deep-fried ball raw material 82 is continuously dropped and supplied into the heating oil 81 in the oil tank 80. Then, the heating oil 81 is taken out from the heating oil outlet 84 provided at the downstream end of the oil tank 80, and the heating oil 81 flows into the oil tank 80 from the heating oil outlet 85 provided at the upstream end of the oil tank 80. A heating oil circulation path 86 is provided. Also, above the oil tank 80, there is a scraper plate 88a for transferring the fried ball 87 produced by dropping the fried ball raw material 82 into the heated oil 81 and floating on the surface of the heated oil 81 from the upstream side toward the downstream side. A fried ball transfer mechanism 88 comprising a chain conveyor 88b is provided.
In the illustrated fried ball manufacturing apparatus B, 89 is a fried ball collection box, 90 is a heating means for heating the oil tank 80, and 91 is a circulation pump provided in the heating oil circulation path 86.
[0004]
With the configuration described above, the heating oil 90 in the oil tank 80 is heated to a predetermined temperature by the heating means 90, and the circulation pump 91 provided in the heating oil circulation path 86 is driven to pass the heating oil outlet 84 from the oil tank 80. While taking out the heating oil 81, the heating oil 81 flows out into the oil tank 80 through the heating oil outlet 85, and the heating oil 81 in the oil tank 80 flows from the upstream side to the downstream side at a gentle speed. Further, the fried ball transfer mechanism 88 is driven to rotate the chain conveyor 88b, and the scraper plate 88a is moved from the upstream side to the downstream side along the surface of the heating oil 81.
Thereafter, when the viscous deep-fried ball raw material 82 is continuously dropped and supplied into the heating oil 81 in the oil tank 80 from the raw material supply mechanism 83 and supplied, the heated oil 81, a spherical fried ball 87 can be produced. Since such a deep-fried ball 87 sinks a considerable depth from the oil surface and then has a specific gravity lighter than that of the oil, it gradually floats and floats on the surface of the heating oil 81. Thereafter, the inside of the oil tank 80 is transferred from the upstream side to the downstream side by the scraper 88 a of the fried ball transfer mechanism 88, discharged from a discharge port provided on the downstream side of the oil tank 80, and collected in the fried ball collection box 89.
Thus, by using the fried ball manufacturing apparatus B, the fried balls 87 can be mass-produced.
[0005]
[Problems to be solved by the invention]
However, the fried ball manufacturing apparatus B having the above-described configuration still has the following problems to be solved.
That is, as shown in FIG. 8, the circulation pump 91 provided in the heating oil circulation path 86 is driven, and the flow of the heating oil 81 flowing out into the oil tank 80 through the heating oil outlet 85 becomes a turbulent flow upward. After moving, it will flow downstream. Therefore, the fried ball raw material 82 continuously supplied in granular form from the raw material supply mechanism 83 into the heating oil 81 falls into the heating oil 81 in a turbulent flow state. Since not only the flow is disturbed but also the heating oil 81 flows only from the upstream side toward the downstream side, as shown in FIG. 8, heating is performed while making a complicated movement in the heating oil 81. It floats on the surface of the oil 81. As a result, the fried balls 87 interfere with each other, collide with each other, and partly get stuck or integrated to produce a fried ball 87 having a different size and shape, thereby significantly reducing the commercial value of the fried balls 87. Become.
[0006]
This invention is made | formed in view of such a situation, has a uniform shape and a uniform particle size, and has produced the fried ball manufacturing method and apparatus which can mass-produce the fried ball which can raise a commercial value remarkably. The purpose is to provide.
[0007]
[Means for Solving the Problems]
The fried ball manufacturing method according to the present invention that meets the above-described object is a method in which a thick fried ball raw material is spheroidized by the surface tension of the fried ball raw material from a fried ball raw material outflow nozzle consisting of a large number of small holes and continuously dropped into the heated oil. and, wherein the flow of the heating oil at the location where Agedama feedstock is fed into the heating oil, via a rectifier generating mechanism provided in the heating oil on the upstream side of a position where the Agedama raw material falls, the heating the Agedama material from the surface of the oil to the laminar flow toward the downstream side from an upstream side to a position that dropping the heating in oil, the Agedama raw material dropped lifted heated while passing downstream in the heating oil Manufacturing fried balls with uniform shape and uniform particle size.
In this case, since the rectification is ensured not only in the upper layer part but also in the lower layer part, the uniform flow of the heating oil (rectified flow) over the entire length of the depth at which the fried ball raw material falls (for example, 150 mm from the surface of the heating oil) ) Can be secured. Therefore, the fried ball material once dropped to the lower layer of the heated oil then moves horizontally toward the downstream side for a certain distance, then becomes a fried ball and floats while gradually drawing a parabola up to the surface of the heated oil with an upward gradient. Will do. Therefore, the granular fried ball raw materials can be deeply fried in an independent sphere state to produce fried balls having a uniform shape and a uniform particle size, and the commercial value of the fried balls can be increased.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
First, with reference to FIG.1 and FIG.2, the whole structure of the fried ball manufacturing apparatus A which concerns on one embodiment of this invention is demonstrated.
As shown in the figure, heating oil 11 is stored in an oil tank 10 having a long box shape whose upper surface is open. Above the upstream side of the oil tank 10, a raw material supply mechanism 13 for supplying the viscous deep-frying ball raw material 12 by dropping continuously into the heating oil 11 in the oil tank 10 in a granular form is disposed.
Heating oil 11 is extracted from the heating oil outlet 14 provided at the downstream end of the oil tank 10, and the heating oil 11 flows into the oil tank 10 from the heating oil outlet 15 provided at the upstream end of the oil tank 10. A circulation path 16 is provided, and a circulation pump 17 is attached to a middle portion of the heating oil circulation path 16.
[0012]
Above the oil tank 10, a chain conveyor with a scraper 19 that transports the fried balls 18 that are produced by dropping the fried ball raw material 12 into the heated oil 11 and float on the surface of the heated oil 11 from the upstream side toward the downstream side. A fried ball transfer mechanism 21 comprising 20 is disposed.
In the heating oil 11, the flow of the heating oil 11 from the surface of the heating oil 11 to the depth at which the frying ball raw material 12 falls (the most dropped position) is downstream from the upstream side where the frying ball raw material 12 falls. A rectification generating mechanism 22 for rectifying flowing in layers toward the side is disposed.
Below the oil tank 10, a plurality of burners 23, which are examples of heating means for heating the oil tank 10, are disposed. An electric heater can be used instead of the burner 23.
A frying ball collection box 24 that collects the fried balls 18 produced by the fried ball production apparatus A is connected to the downstream end of the oil tank 10.
[0013]
Next, the structure of each part of the fried ball manufacturing apparatus A having the above-described structure will be described in detail with reference to FIGS.
As shown in FIG. 1, the upstream side of the long oil tank 10 includes the falling fried ball raw material 12 in the heating oil 11, including the part where the granular fried ball raw material 12 falls from the raw material supply mechanism 13. It is deep so that it can be immersed to a sufficient depth. On the other hand, the downstream side of the oil tank 10 is shallow as long as it has sufficient depth to float the fried balls 18 on the surface, and there is an inner surface between the deep bottom portion 25 and the shallow bottom portion 26. An inclined portion 27 for smoothly lifting the fried ball 18 is formed. In addition, a pair of heating oil outlets 15 are provided at the upstream end of the deep bottom portion 25 at intervals in the width direction.
[0014]
As shown in FIG. 1 and FIG. 2, the raw material supply mechanism 13 is disposed in a lower part of the hopper 28, which stores the viscous Meriken powder while stirring and can quantitatively cut it downward. At the same time, it is composed of a horizontally long bread 30 having a frying ball material outflow nozzle 29 consisting of a large number of small holes on its lower surface. The granular fried ball raw material 12 can be continuously dropped and supplied into the heating oil 11 through the fried ball raw material outflow nozzle 29.
[0015]
In the fried ball transfer mechanism 21 shown in FIGS. 1 and 2, the chain conveyor 20 is composed of a pair of endless chains 31 disposed above the oil tank 10 at a parallel interval in the width direction. In addition, a large number of scraping plates 19 are installed at a predetermined pitch in the longitudinal direction via attachments. As shown in the figure, each scraper plate 19 is formed of a horizontally long rectangular plate, and both ends thereof are disposed at positions that substantially contact the inner surfaces of both side walls of the oil tank 10. The chain conveyor 20 is rotationally driven by a rotation motor 34 that is linked to a rotation shaft 33 to which a downstream sprocket 32 is fixed.
[0016]
In the rectification generating mechanism 22 shown in FIGS. 1 to 4, there is an upper and lower space above the heating oil outlet 15 provided at the deep bottom portion 25 of the oil tank 10 and flowing out the heating oil 11 upward. First and second heating oil guide plates 35 and 36 are arranged in a superposed state. The base portions of the first and second heating oil guide plates 35 and 36 are connected to the upstream peripheral portion of the heating oil outlet 15, respectively, and the tip portion extends upward while drawing an arc. Further, a communication opening 37 having a horizontally long rectangular shape is provided at the base of the second heating oil guide plate 36.
Therefore, the upper rectification flow path 38 in which the heating oil 11 from the heating oil outlet 15 flows in an arc shape through the communication opening 37 between the first and second heating oil guide plates 35 and 36 can be formed. A lower rectification flow path 39 can be formed on the lower surface of the second heating oil guide plate 36.
[0017]
Next, the fried ball manufacturing method which manufactures the fried ball 18 using the fried ball manufacturing apparatus A which has an above-described structure is demonstrated.
First, the heating oil 11 in the oil tank 10 is heated to a predetermined temperature (for example, 170 ° to 200 °) by the burner 23, and the circulation pump 17 provided in the heating oil circulation path 16 is driven to heat from the oil tank 10. The heating oil 11 is taken out through the oil outlet 14, and the heating oil 11 flows out into the oil tank 10 through the heating oil outlet 15. The heating oil 11 in the oil tank 10 flows from the upstream side to the downstream side at a gentle speed. Further, the frying ball transfer mechanism 21 is driven to rotate the chain conveyor 20, and the scraper 19 is moved along the surface of the heating oil 11 from the upstream side to the downstream side.
[0018]
After that, when the viscous fried ball raw material 12 is continuously dropped and supplied from the raw material supply mechanism 13 into the heated oil 11 in the oil tank 10 in a granular form, the heated oil is made spherical by the surface tension of the fried ball raw material 12. 11, a spherical fried ball 18 can be produced. Since such a deep-fried ball 18 sinks a considerable depth from the oil surface and then has a specific gravity lighter than that of the oil, it gradually floats and floats on the surface of the heating oil 11. Thereafter, the inside of the oil tank 10 is transferred from the upstream side to the downstream side by the scraper 19 of the fried ball transfer mechanism 21, discharged from the discharge port 40 provided on the downstream side of the oil tank 10, and collected in the fried ball collection box 24. .
Thus, by using the fried ball manufacturing apparatus A, the fried balls 18 can be mass-produced.
[0019]
Further, in the present embodiment, the upper rectification flow path 38 in which the heating oil 11 flows in an arc shape between the first and second heating oil guide plates 35 and 36 and the lower surface of the second heating oil guide plate 36 are provided. Since the lower rectification forming flow path 39 is formed, the fried ball raw material 12 continuously supplied in granular form from the raw material supply mechanism 13 into the heating oil 11 can be dropped into the rectified heating oil 11. Moreover, since rectification is ensured not only in the upper layer part but also in the lower layer part, a uniform flow of the heating oil 11 can be secured over the entire length of the depth at which the fried ball raw material 12 falls. Therefore, the fried ball raw material 12 once dropped to the lower layer portion of the heating oil 11 is then horizontally moved toward the downstream side by a certain distance and then gradually floats up to the surface of the heating oil 11 with an upward gradient. That is, as the fried ball raw material 12 is dropped, heat exchange begins in the upper layer, and as the water evaporates and sinks toward the lower layer, the buoyancy gradually increases and the buoyancy becomes maximum at the lowest drop position of the lower layer and the drop energy Disappears. Thereafter, the fried ball 18 floats on the surface of the heating oil 11 while drawing a parabola by the flow in the lower layer. As a result, it is possible to manufacture the fried balls 18 that are sufficiently fried in the form of independent spheres and have a uniform shape and a uniform particle size, and the commercial value of the fried balls 18 can be increased.
[0020]
FIG. 5 shows a fried ball manufacturing apparatus A1 according to a modification of the fried ball manufacturing apparatus A described above. As shown in the figure, since the fried ball manufacturing apparatus A1 has substantially the same configuration as the fried ball manufacturing apparatus A except for the following configuration, the same components are denoted by the same reference numerals.
As shown in the figure, in this modification, the flow energy from the upstream side to the downstream side is given to the heating oil 11 between the location in the oil tank 10 where the fried ball raw material 12 falls and the upstream side end of the fried ball transfer mechanism 21. The rotating paddle 41 which is an example of the fried ball retention prevention mechanism which pushes the fried ball 18 which gave and floated to the downstream is arrange | positioned.
By adopting such a configuration, the granular deep-frying ball raw material 12 is further actively separated and sufficiently fried in an independent sphere state, and a deep-frying ball 18 having a uniform shape and a uniform particle size can be manufactured. The product value of the fried ball 18 can be further increased. Moreover, since the line speed of fried ball manufacturing apparatus A1 can be raised, it can manufacture in larger quantities.
[0021]
6 and 7 show a fried ball manufacturing apparatus A2 according to a modified example of the fried ball manufacturing apparatus A described above. As shown in the figure, the fried ball manufacturing apparatus A2 includes a rectifying and generating mechanism 42 corresponding to the rectifying and generating mechanism 22 of the fried ball manufacturing apparatus A inside the vertical partition plate 43 and the horizontal partition plate on the upstream side of the location where the fried ball raw material 12 falls. The guide tube 45 is divided by 44 and extends in the longitudinal direction, and upper and lower rectification forming channels 46 and 47 are provided inside the guide tube 45.
Also in this case, since the rectification can be easily and surely formed not only in the upper layer portion but also in the lower layer portion at the location of the heating oil 11 where the granular fried ball raw material 12 falls with a simple structure, The deep-fried ball raw material 12 can be deeply fried in an independent sphere state to produce the deep-fried balls 18 having a uniform shape and a uniform particle size, and the commercial value of the deep-fried balls 18 can be increased.
[0022]
As described above, the present invention has been described with reference to one embodiment. However, the present invention is not limited to the configuration described in the above embodiment, and is described in the claims. Other embodiments and modifications conceivable within the scope of the above are also included.
[0023]
【The invention's effect】

The flow of rectified flow allows granular frying ball raw material to fall continuously into the heating oil, and since rectification is secured not only in the upper layer part but also in the lower layer part, the depth at which the fried ball raw material falls A uniform flow of heated oil can be ensured over the entire length of. Therefore, the fried ball material once dropped to the lower layer of the heated oil becomes a fried ball while drawing a parabola forward and floats to the surface of the heated oil, producing a fried ball having a uniform shape and a uniform particle size Can increase the commercial value of fried balls.
[0024]
In the fried ball manufacturing apparatus according to claims 2 and 3 , the raw material supply mechanism can continuously fall into the heated oil in the rectified state in a granular form, and the rectification is ensured not only in the upper layer part but also in the lower layer part. Therefore, it is possible to mass-produce fried balls with high commercial value having a uniform shape and a uniform particle size that are sufficiently fried in an independent spherical state.
[0025]
Then, the rectification generating mechanism is formed in an upper rectification mode in which the heating oil from the heating oil outlet flows in an arc shape by the first and second heating oil guide plates provided above and below the heating oil outlet at intervals. In addition to forming the flow path and forming the lower rectification flow path on the lower surface of the second heating oil guide plate, not only the upper layer part but also the lower layer part at the location of the heated oil where the granular fried ball raw material falls The rectification can be easily and reliably formed, and a fried ball having a uniform shape and a uniform particle size and having a high commercial value can be manufactured.
[0026]
In the fried ball manufacturing apparatus according to claim 3 , since the fried ball retention preventing mechanism is disposed between the portion where the fried ball raw material falls and the upstream end of the fried ball transfer mechanism, the fried ball that has floated on the surface of the heated oil is floated. It can prevent staying in a part, can raise the line speed of a fried ball manufacturing apparatus, and can manufacture fried balls more reliably in large quantities.
