Description

【0001】
【発明の属する技術分野】
本発明は、水を殺菌処理する飲料物殺菌方法及びその装置に関するものである。
【0002】
【従来の技術】
一般的に、自動販売機は、図12に示す如く、氷水や湯を供給する水供給ライン1と、コーヒー、紅茶、日本茶、清涼飲料等の粉末や原液の原料を供給する原料供給ライン2とを備え、水供給ライン1には、所定量の水を貯留した水タンク3と、水タンク3から供給ポンプ4及び水フィルタ5を介して水を一時的に溜めるシスターン6と、シスターン6から水を供給されて氷水を製造する製氷機7と、シスターン6から水を供給されて湯を沸かす湯タンク8等を備えており、原料供給ライン2には、原料を供給するキャニスタ9を備えている。
【0003】
自動販売機が飲料物を提供する際には、水供給ライン1からシスターン6を介して水を供給すると共に原料供給ライン2から原料を供給し、水と原料の混合により所望の飲料物にしてカップ等の容器10に注いでいる。
【0004】
又、近年、消費先の要求等から水等を殺菌することが求められているため、自動販売機の中にはシスターン6の内部もしくはシスターン6の近傍の流路位置に、塩素を発生して水を塩素殺菌処理する塩素発生器(図示せず)や、波長254nm等を含む紫外光を照射して水を光殺菌処理する連続紫外線ランプ(図示せず)が備えられている。ここで、連続紫外線ランプの照射光に含まれる光の波長の254nm付近の領域は、図13に示す如く、殺菌作用の分光特性により殺菌効果が高いことが明らかである。
【0005】
【発明が解決しようとする課題】
しかしながら、塩素発生器を用いて水を塩素殺菌処理する場合には、水に残留塩素が生じ、飲料物(特に抽出処理したコーヒー等)の香味が劣化するという問題があった。又、連続紫外線ランプを用いて水を光殺菌処理する場合には、照射のチャージングに時間が掛かることに対応して、連続紫外線ランプを常に連続点灯させる必要があるため、連続紫外線ランプの寿命が短く、ランニングコストが高いという問題があった。
【0006】
本発明は上述の実情に鑑みてなしたもので、塩素の殺菌処理や連続紫外線ランプの使用を不要にして飲料物を殺菌し得る飲料物殺菌方法及びその装置を提供することを目的としている。
【0007】
【課題を解決するための手段】
本発明の請求項1は、水を流下させると同時に、紫外光を含む閃光を水の流下方向に沿うよう照射して流下中の水を殺菌処理することを特徴とする飲料物殺菌方法、に係るものである。
【0008】
本発明の請求項2は、水面を露出させるよう上部を開放して一側から他側へ水を流す水路と、該水路の上部に位置して水路の流路方向に延在するフラッシュランプとを備え、前記フラッシュランプより紫外光を含む閃光を照射して流下中の水を殺菌処理し得るよう構成したことを特徴とする飲料物殺菌装置、に係るものである。
【0009】
又、本発明の請求項3に示す如く、水路は、水面の露出が大きくなるよう流路面を大きく形成した浅底の流路体でもよい。
【0010】
更に、請求項4に示す如く、水に対するフラッシュランプの後方に、光を反射させて水面の方向へ向かわせる反射板を備えてもよい。
【0011】
本発明の請求項5は、透過材で構成されて水を流し得る流路管と、該流路管に隣接して流路管の流路方向に延在するフラッシュランプとを備え、前記フラッシュランプにより紫外光を含む閃光を照射して流下中の水を殺菌処理し得るよう構成したことを特徴とする飲料物殺菌装置、に係るものである。
【0012】
又、本発明の請求項6に示す如く、流路管とフラッシュランプを囲む筒状の反射板を備え、前記反射板により光を反射させて流路管へ向かわせるよう構成してもよい。
【0013】
更に又、請求項7に示す如く、フラッシュランプは、照射一回あたり0.01J/mL〜10J/mLの照射エネルギーを発生させるよう構成されるものであり、請求項8に示す如く、フラッシュランプは、振動数1Hz〜100Hz、発光時間1.0μS〜1.0mS、出力範囲0.2W〜500Wにより構成されるものである。
【0014】
飲料物を提供する際には、流下する水を、紫外光を含む閃光により殺菌処理し、飲料物にするよう供給する。
【0015】
このように、本発明の請求項1、2又は5によれば、紫外光を含む閃光により流下中の水を殺菌処理するので、塩素殺菌処理を不要にして残留塩素の発生を無くし、飲料物の香味の劣化を防止することができる。又、塩素等の他の物質を使用しないので、衛生管理を容易にすると共にサニテーション性を向上させることができる。更に、本発明の請求項2又は5によれば、フラッシュランプを連続点灯することなく必要に応じて使用し得るので、フラッシュランプの寿命を延ばすと共に電気消費量を抑制し、ランニングコストを低減することができる。更に又、本発明の請求項5によれば、流路管を流れる水は外気に触れることがないので、水中へ菌が侵入することを防止し、殺菌処理の効率低下を防止することができる。
【0016】
本発明の請求項3に示す如く、水路は、水面の露出が大きくなるよう流路面を大きく形成した浅底の流路体であると、露出する水面が照射エネルギーを十分に受けると共に浅底により水の底にまで閃光が到達するので、水を効率的に殺菌処理することができる。
【0017】
本発明の請求項4に示す如く、水に対するフラッシュランプの後方に、光を反射させて水面の方向へ向かわせる反射板を備えると、照射エネルギーを無駄にすることなく照射し得るので、水を効率的に殺菌処理することができる。
【0018】
本発明の請求項6に示す如く、流路管とフラッシュランプを囲む筒状の反射板を備え、前記反射板により光を反射させて流路管へ向かわせるよう構成すると、流路管と異なる方向に照射された閃光が反射されて流路管に向かうので、流路管の周囲方向から閃光が入射して効率良く殺菌することができる。
【0019】
本発明の請求項7に示す如く、フラッシュランプは、照射一回あたり0.01J/mL〜10J/mLの照射エネルギーを発生させるよう構成され、もしくは、本発明の請求項8に示す如く、フラッシュランプは、振動数1Hz〜100Hz、発光時間1.0μS〜1.0mS、出力範囲0.2W〜500Wにより構成されると、フラッシュランプの紫外光を含む閃光により水を適切に殺菌処理するので、残留塩素の発生を無くして飲料物の香味の劣化を好適に防止することができる。又、フラッシュランプを必要に応じて適切に使用し得るので、フラッシュランプの寿命を更に延ばすと共に電気消費量を確実に抑制し、ランニングコストを一層低減することができる。
【0020】
【発明の実施の形態】
図1〜図4は本発明の飲料物殺菌方法及びその装置を実施する形態の第一例を示すものである。
【0021】
第一例の飲料物殺菌装置は、シスターン6の下流側の配管の中途位置に、水面を露出させるよう上部を開放して一側から他側へ水を流す所定長さの水路11を、フランジ等の接続部材(図示せず)を介して接続し、水路11の上部には、水路11の流路方向に延在して水路11の長さに対応する棒状のフラッシュランプ12を配置し、水に対するフラッシュランプ12の後方には、光を反射させて水面Sの方向へ向かわせる曲面の反射板13を備えている。ここで、水路11は、水面Sの露出が大きくなるよう流路面を大きく形成した浅底の流路体14で構成されており、反射板13はアルミコーティング等の鏡面加工されている。
【0022】
一方、フラッシュランプ12は、振動数1Hz〜100Hz、発光時間1.0μS〜1.0mS、出力範囲0.2W〜500Wの能力を備えて紫外光を発するアーク放電ランプ又はエキシマランプの中から特にキセノンフラッシュランプが選択されており、キセノンフラッシュランプから発する閃光は、水路11を流下する水に一回あたり0.01J/mL〜10J/mLの照射エネルギーを照射するよう構成されている。又、フラッシュランプ12は、ランプ配線15を介して、水路11の外部に配置されたランプ制御部16に接続されており、ランプ制御部16は、飲料物の要求等の外部からの信号を受ける全体制御部17にスイッチ部18を介して接続される演算カウンター19と、演算カウンター19より接続されるパルス発生器20と、パルス発生器20より接続されると共にフラッシュランプ12に接続するコントローラ21とを備えている。ここで、スイッチ部18は、水供給ライン1と原料供給ライン2等に接続されており、飲料物の要求があった場合にはフラッシュランプ12、水供給ライン1と原料供給ライン2等を制御するようにしている。又、図4ではフラッシュランプ12を二つ示しているが、一つでもよいし、三つ以上の複数でもよい。更に、フラッシュランプ12の近傍には空冷ファン(図示せず)を備えてもよい。なお、フラッシュランプ12と水面の間には、図5に示す如く、石英、合成石英、合成フューズドシリカ(アモルファス二酸化シリコン)、溶融石英、合成サファイア(酸化アルミニウム)等の透過材22を掛止してもよい。
【0023】
以下、本発明の飲料物殺菌方法及びその装置を実施する形態の第一例の作用を説明する。
【0024】
自動販売機で飲料物を入れる際には、外部のボタン等を押すことにより飲料物要求信号を全体制御部17に送り、全体制御部17は、飲料物の選択等の種々の判断をしてスイッチ部18より水供給ライン1及び原料供給ライン2に制御信号を送り、水供給ライン1から氷水や湯を供給すると共に原料供給ライン2から原料を供給し、水と原料の混合により所望の飲料物にしてカップ等の容器10に注ぐ。
【0025】
又、同時に、ランプ制御部16では、制御信号より演算カウンター19がパルス発生器20にパルス回数指令を与えるよう信号を送り、パルス発生器20はコントローラ21に単位時間における規則的なパルス信号を送り、コントローラ21はドリガーとして制御してフラッシュランプ12を所定のパルス数で閃光を発生させる。
【0026】
この時、水路11を流下する水は、フラッシュランプ12の紫外光を含む閃光により殺菌処理されている。
【0027】
次に、本発明の飲料物殺菌装置に用いるフラッシュランプ12の殺菌の実験結果について説明する。
【0028】
<実験>
1)供試菌の培養及び調整
供試菌株は、大腸菌(Escherichia coli)、Pseudomonas diminuta、Bacillus pumilus(芽胞)、及びAspergillus niger(胞子)である。大腸菌とPseudomonas diminutaはSCD培地等の培地で増殖させ、滅菌水で希釈し、調整し、菌数が1×10/mlの菌液を得る。芽胞又は胞子の液は次のように調整する。
▲1▼Bacillus pumilusの芽胞液の調整は、寒天培地にて35℃で7日間培養の後、生理食塩水により培地上の胞子を回収し、ガラスビーズ処理、ナイロンメッシュ濾過して80℃で20分間熱処理し、原液菌数約1.0×1010CFU/mlになるよう、遠心集菌後、滅菌水により懸濁して4℃で保存し、更に、芽胞液を滅菌水で希釈し調整し、約1.0×10CFU/mlの菌液を得る。
▲2▼Aspergillus nigerの胞子の調整は、PDA寒天培地にて25℃で7日間培養の後、0.1%Tween80水溶液により培地上の胞子を回収し、約30分間激しく振とうさせてナイロンメッシュ濾過し、原液菌数約1.0×10CFU/mlになるよう、遠心集菌後、滅菌水により懸濁し、更に、滅菌水で希釈し調整し、約1.0×10CFU/mlの菌液を得る。
【0029】
2)照射方法及び照射条件
サンプル液調整は、オートクレーブしたシャーレ(原則として平均内径27mm)に菌液(原則として6ml)を無菌的に入れ、水深11mmとなるよう調整し、フラッシュランプ12により直ちに照射する。ここでサンプル液は、フラッシュランプ12から水面までの距離を15mmにするようフラッシュランプ12の直下に配置し、フラッシュランプ12は、所定の周波数(2Hz〜33Hz)で1秒〜8秒間照射する。
【0030】
3)菌数測定方法
照射後、サンプル液0.1mlを寒天平板に塗布し、所定温度で、24h〜48h培養し、コロニーカウントを行った。コロニー数がカウントに適さないほど多くなりそうなサンプルでは、サンプル液を10倍希釈した後、上記の操作を行なった。以下、結果を〔表1〕に示す。
【0031】
【表1】

Figure 2004057845
【0032】
その結果、大腸菌は、1mlの液に対し2回の閃光(パルス)を照射した場合(菌液量に対するフラッシュランプ12の入力エネルギー量は0.67J/ml)、その44%が殺菌され、4回の閃光(1.33J/ml)を照射した場合では、その85%が殺菌され、8回の閃光(2.67J/ml)を照射した場合では、その99.99%以上が殺菌された。他の細菌では、大腸菌より効果が弱いものの、照射を強力にすることにより99.8%以上の殺菌効果が認められた。カビ類であるAspergillus nigerの胞子は特に耐性が強かったが、入力エネルギーを更に高めることにより、99%まで殺菌できた。Aspergillus nigerの胞子は液量を16.9mlまで増加しても容積あたりの入力エネルギーが確保されれば殺菌効果は低下しなかった。
【0033】
従って、衛生上の指標とされている大腸菌に注目すれば、その50%〜99.99%を殺菌する条件(菌液量に対するフラッシュランプ12の入力エネルギー量)は0.7J/ml〜2.7J/mlであった。また、薬剤等の抵抗性の強いBacillus属の細菌に対しても、11.0J/mlの照射で99.99%以上が殺菌できた。即ち0.7J/ml〜11.0J/mlの入力エネルギーを与えることにより、水を適確に殺菌することができる。ここで、照射エネルギーが0.7J/ml未満の場合には十分に殺菌することができず、11.0J/mlより大きい場合には、ムダなエネルギーが多いという問題がある。
【0034】
このように、紫外光を含む閃光により流下中の水を殺菌処理するので、塩素殺菌処理を不要にして残留塩素の発生を無くし、飲料物の香味の劣化を防止することができる。又、塩素等の他の物質を使用しないので、衛生管理を容易にすると共にサニテーション性を向上させることができる。更に、フラッシュランプ12を連続点灯することなく必要に応じて使用し得るので、フラッシュランプ12の寿命を延ばすと共に電気消費量を抑制し、ランニングコストを低減することができる。
【0035】
水路11は、水面Sの露出が大きくなるよう流路面を大きく形成した浅底の流路体14であると、露出する水面Sが照射エネルギーを十分に受けると共に浅底により水の底にまで閃光が到達するので、水を効率的に殺菌処理することができる。
【0036】
水に対するフラッシュランプ12の後方に、光を反射させて水面Sの方向へ向かわせる反射板13を備えると、照射エネルギーを無駄にすることなく照射し得るので、水を効率的に殺菌処理することができる。
【0037】
フラッシュランプ12は、照射一回あたり0.01J/mL〜10J/mLの照射エネルギーを発生させるよう構成されると共に、フラッシュランプ12は、振動数1Hz〜100Hz、発光時間1.0μS〜1.0mS、出力範囲0.2W〜500Wにより構成されると、フラッシュランプ12の紫外光を含む閃光により水を適切に殺菌処理するので、残留塩素の発生を無くして飲料物の香味の劣化を好適に防止することができる。又、フラッシュランプ12を必要に応じて適切に使用し得るので、フラッシュランプ12の寿命を更に延ばすと共に電気消費量を確実に抑制し、ランニングコストを一層低減することができる。
【0038】
図6〜図11は本発明の飲料物殺菌方法及びその装置を実施する形態の第二例を示すものである。
【0039】
第二例の飲料物殺菌装置は、シスターン6の下流側の配管23に備えられるよう、透過材で構成されて水を流す所定長さの流路管24を備え、流路管24の上方隣接位置には、流路管24の流路方向に延在して流路管24の長さに対応するよう、第一例と略同様な性能及びランプ制御部16を備えた棒状のフラッシュランプ25を配置し、流路管24とフラッシュランプ25の外方には、流路管24とフラッシュランプ25を囲むよう、上側反射部26aと下側反射部26bにより開閉可能な円筒状の反射板26を備えている。なお、流路管24と配管23の接続は、流路管24の端部に備えられた差込部材27と、配管23の端部に備えられた受入部材28を締結することにより、差込部材27の差込面29と受入部材28の受入面30を面接触させて流路管24と配管23の間から漏れがないように接続している。
【0040】
ここで、流路管24の透過材は、石英、合成石英、合成フューズドシリカ(アモルファス二酸化シリコン)、溶融石英、合成サファイア(酸化アルミニウム)等で形成されており、円筒状の反射板26は、支持部材31,32を介してフラッシュランプ25及び流路管24を所定位置に配置し、フラッシュランプ25からの閃光が反射により流路管24に集まるよう、断面形状が真円で形成されると共にアルミコーティング等の鏡面加工が施されている。又、円筒状の反射板26は、図11に示す如く、断面形状を楕円で形成し、流路管24を楕円の焦点位置に配置してもよい。
【0041】
以下、本発明の飲料物殺菌方法及びその装置を実施する形態の第二例の作用を説明する。
【0042】
自動販売機で飲料物を入れる際には、第一例と略同様に処理し、フラッシュランプ25の紫外光を含む閃光により流路管24内の水を殺菌処理している。
【0043】
このように、流路管24を流れる水は外気に触れることがないので、水中へ菌が侵入することを防止し、殺菌処理の効率低下を防止することができる。又、第二例の飲料物供給方法及びその装置によれば、第一例と略同様な作用効果を得ることができる。
【0044】
更に、流路管24とフラッシュランプ25を囲む筒状の反射板26を備え、前記反射板26により光を反射させて流路管24へ向かわせるよう構成すると、流路管24と異なる方向に照射された閃光が反射されて流路管24に向かうので、流路管24の周囲方向から閃光が入射して効率良く殺菌することができる。更に又、反射板26の断面形状を楕円で形成して流路管24を楕円の焦点位置に配置すると、フラッシュランプ25からの閃光が反射板26により流路管24に適切に集まるので、流路管24の周囲方向から閃光が入射して効率良く確実に殺菌することができる。
【0045】
なお、本発明の飲料物殺菌方法及びその装置は、上述の形態例にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【0046】

[0027]
Next, experimental results of sterilization of the flash lamp 12 used in the beverage sterilization apparatus of the present invention will be described.
[0028]
<Experiment>
1) Culture and preparation of test bacteria The test strains are Escherichia coli, Pseudomonas diminuta, Bacillus pumilus (spores), and Aspergillus niger (spores). Escherichia coli and Pseudomonas diminuta are grown on a medium such as SCD medium, diluted with sterilized water, and adjusted to obtain a bacterial solution having a bacterial count of 1 × 10 5 / ml. The spore or spore solution is prepared as follows.
{Circle around (1)} The spore solution of Bacillus pumilus was prepared by culturing on an agar medium at 35 ° C. for 7 days, collecting spores on the medium with physiological saline, treating with glass beads, filtering with nylon mesh, and adjusting the temperature at 80 ° C. for 20 days. heat-minutes, so as to be approximately 1.0 × 10 10 CFU / ml count stock bacteria after centrifugation collection bacteria were suspended by sterile water and stored at 4 ° C., further adjusted by diluting the spore solution with sterile water , About 1.0 × 10 4 CFU / ml.
{Circle around (2)} Aspergillus niger spores are prepared by culturing on a PDA agar medium at 25 ° C. for 7 days, collecting spores on the medium with a 0.1% Tween 80 aqueous solution, and shaking vigorously for about 30 minutes to obtain a nylon mesh. After filtration, the cells were collected by centrifugation, suspended in sterile water, diluted with sterile water and adjusted to about 1.0 × 10 4 CFU / ml so that the number of undiluted bacteria was about 1.0 × 10 7 CFU / ml. Obtain ml of bacterial solution.
[0029]
2) Irradiation Method and Irradiation Condition The sample liquid was adjusted by aseptically putting a bacterial solution (in principle, 6 ml) into an autoclaved petri dish (in principle, an average inner diameter of 27 mm), adjusting the water depth to 11 mm, and immediately irradiating with a flash lamp 12. I do. Here, the sample liquid is disposed immediately below the flash lamp 12 so that the distance from the flash lamp 12 to the water surface is 15 mm, and the flash lamp 12 irradiates at a predetermined frequency (2 Hz to 33 Hz) for 1 second to 8 seconds.
[0030]
3) Method for counting the number of bacteria After irradiation, 0.1 ml of a sample solution was applied to an agar plate, cultured at a predetermined temperature for 24 to 48 hours, and colony count was performed. For a sample in which the number of colonies is likely to be so large that it is not suitable for counting, the above operation was performed after diluting the sample solution 10-fold. Hereinafter, the results are shown in [Table 1].
[0031]
[Table 1]
Figure 2004057845
[0032]
As a result, when E. coli is irradiated with two flashes (pulses) of 1 ml of the liquid (the input energy amount of the flash lamp 12 with respect to the amount of the bacterial liquid is 0.67 J / ml), 44% of the E. coli is sterilized. When the flash (1.33 J / ml) is irradiated, 85% of the light is sterilized, and when the flash (2.67 J / ml) is irradiated, 99.99% or more of the light is sterilized. . Other bacteria were less effective than Escherichia coli, but 99.8% or more of a bactericidal effect was observed by intensifying the irradiation. The spores of the mold Aspergillus niger were particularly resistant, but could be killed to 99% by further increasing the input energy. Aspergillus niger spores did not reduce the bactericidal effect even if the liquid volume was increased to 16.9 ml as long as the input energy per volume was secured.
[0033]
Therefore, if attention is paid to Escherichia coli, which is an indicator of hygiene, the conditions for sterilizing 50% to 99.99% of the E. coli (the amount of input energy of the flash lamp 12 with respect to the amount of bacterial solution) are 0.7 J / ml to 2. It was 7 J / ml. In addition, even against bacteria of the genus Bacillus having high resistance such as drugs, 99.99% or more could be sterilized by irradiation of 11.0 J / ml. That is, by applying an input energy of 0.7 J / ml to 11.0 J / ml, water can be sterilized accurately. Here, when the irradiation energy is less than 0.7 J / ml, it cannot be sufficiently sterilized. When the irradiation energy is more than 11.0 J / ml, there is a problem that much energy is wasted.
[0034]
As described above, since the flowing water is sterilized by the flash light including the ultraviolet light, the chlorine sterilization is not required, the generation of residual chlorine is eliminated, and the deterioration of the flavor of the beverage can be prevented. In addition, since other substances such as chlorine are not used, sanitary management can be facilitated and sanitation can be improved. Further, since the flash lamp 12 can be used as required without being continuously turned on, the life of the flash lamp 12 can be extended, the power consumption can be suppressed, and the running cost can be reduced.
[0035]
When the water channel 11 is a shallow channel member 14 having a large channel surface formed so that the water surface S is exposed to a large extent, the exposed water surface S receives sufficient irradiation energy and flashes to the bottom of the water due to the shallow bottom. , The water can be efficiently sterilized.
[0036]
If a reflection plate 13 that reflects light and is directed toward the water surface S is provided behind the flash lamp 12 for water, irradiation can be performed without wasting irradiation energy, so that water can be efficiently sterilized. Can be.
[0037]
The flash lamp 12 is configured to generate irradiation energy of 0.01 J / mL to 10 J / mL per irradiation, and the flash lamp 12 has a frequency of 1 Hz to 100 Hz and a light emission time of 1.0 μS to 1.0 mS. When the output range is 0.2 W to 500 W, the water is appropriately sterilized by the flash light including the ultraviolet light of the flash lamp 12, so that the generation of residual chlorine is eliminated and the deterioration of the flavor of the beverage is suitably prevented. can do. In addition, since the flash lamp 12 can be appropriately used as required, the life of the flash lamp 12 can be further extended, the electric power consumption can be reliably suppressed, and the running cost can be further reduced.

The connection between the flow pipe 24 and the pipe 23 is performed by fastening an insertion member 27 provided at an end of the flow pipe 24 and a receiving member 28 provided at an end of the pipe 23. The insertion surface 29 of the member 27 and the receiving surface 30 of the receiving member 28 are brought into surface contact with each other so that there is no leakage from between the flow pipe 24 and the pipe 23.
[0040]
Here, the transmission material of the channel tube 24 is formed of quartz, synthetic quartz, synthetic fused silica (amorphous silicon dioxide), fused quartz, synthetic sapphire (aluminum oxide), or the like. The flash lamp 25 and the flow tube 24 are arranged at predetermined positions via the support members 31 and 32, and the cross-sectional shape is formed in a perfect circle so that the flash light from the flash lamp 25 is collected in the flow tube 24 by reflection. In addition, mirror finishing such as aluminum coating is applied.

Further, according to the beverage supply method and the apparatus of the second example, substantially the same operation and effect as the first example can be obtained.
[0044]
Further, when a tubular reflecting plate 26 surrounding the flow tube 24 and the flash lamp 25 is provided, and the light is reflected by the reflecting plate 26 and directed toward the flow tube 24, the light is reflected in a direction different from that of the flow tube 24. The emitted flash light is reflected and travels toward the flow pipe 24, so that the flash light is incident from the surrounding direction of the flow pipe 24 and sterilization can be performed efficiently. Furthermore, when the cross-sectional shape of the reflector 26 is formed in an elliptical shape and the flow tube 24 is disposed at the focal position of the ellipse, the flash light from the flash lamp 25 is appropriately collected in the flow tube 24 by the reflector 26, so that the flow Flash light is incident from the peripheral direction of the duct 24, and sterilization can be performed efficiently and reliably.
