Description

本発明は、野菜や海藻等の食品に付着したゴミ等（虫や異物汚れ等）を洗い流すために用いられる食品洗浄装置に関する。 The present invention relates to a food washing apparatus used for washing away dust (insects, foreign matter dirt, etc.) adhering to food such as vegetables and seaweed.

従来、野菜等の洗浄対象食品を洗浄水槽内で洗浄させるようにした食品洗浄装置が提案されている（特許文献１参照）。 2. Description of the Related Art Conventionally, a food cleaning apparatus has been proposed in which foods to be cleaned such as vegetables are cleaned in a cleaning water tank (see Patent Document 1).

この食品洗浄装置は、噴射ノズルによって洗浄水槽内へ空気と水を同時に噴射し、洗浄水に回転水流を与えることで洗浄するように形成されていた。
しかしながら、従来のように回転水流を与える洗浄方法では、水流が単に渦流になって流動するだけになるため、個々の被洗浄食品が分散せずに渦状に回転するだけになり、これでは十分な洗浄効果が得られないという問題があった。 This food washing apparatus was formed so that air and water were simultaneously jetted into a washing water tank by an injection nozzle, and washing was performed by applying a rotating water flow to the washing water.
However, in the conventional washing method that gives a rotating water flow, the water flow is simply swirled and flows, so that the individual foods to be washed only rotate in a vortex without being dispersed. There was a problem that the cleaning effect could not be obtained.

また、従来、前記洗浄水槽の底部に空気噴出管を配設させることで曝気用ブロアからの空気を洗浄室内で上向きに噴出させるようにした食品洗浄装置が提案されている（特許文献２参照）。 Conventionally, a food washing apparatus has been proposed in which an air jet pipe is disposed at the bottom of the washing water tank so that air from the aeration blower is jetted upward in the washing chamber (see Patent Document 2). .

しかしながら、従来のように空気を洗浄水槽の底部から上向きに噴射させる場合、この空気噴出装置に他に水流を生じさせるための給水装置が必要になる。
このように空気噴出装置と給水装置を別々に設ける必要があるため、コスト的に不利になるし、清掃等のメンテナンスや装置のコンパクト化に不利になるという問題があった。 However, when air is jetted upward from the bottom of the washing water tank as in the prior art, a water supply device is additionally required for generating a water flow in the air jetting device.
Thus, since it is necessary to provide an air ejection apparatus and a water supply apparatus separately, there existed a problem that it became disadvantageous in terms of cost, and it became disadvantageous for maintenance, such as cleaning, and compactness of an apparatus.

At this time, aeration and water flow due to the bubbles are uniformly dispersed throughout the cleaning water tank. By spraying so that the food to be cleaned can be swept evenly from the bottom and lifted up and down so that it can be cracked, the cost, maintenance, and compactness can be achieved. It is an object of the present invention to provide a food cleaning apparatus that is advantageous in the above.

The washing basket (9) is provided with a bottom screen (92) at the bottom of the cylindrical body (90) and a screen cylinder (93) at the upper end (95) of the cylindrical body (90). In addition, a water flow blocking portion (92a) is formed in the central portion of the bottom screen (92).

本発明の食品洗浄装置（請求項１）では、洗浄に際し、洗浄水槽の底部から含気水を噴射させるもので、このとき圧力水管の先端に噴射ストレーナを取り付けているため、含気水である気泡と水流を洗浄水槽の全体に亘って均一に分散させるように噴射させることができる。 In the food washing apparatus of the present invention (Claim 1), the aerated water is jetted from the bottom of the washing water tank at the time of washing. At this time, since the spray strainer is attached to the tip of the pressure water pipe, the aerated water The bubbles and the water flow can be sprayed so as to be uniformly dispersed throughout the washing water tank.

これにより、洗浄対象食品を全体的に満遍なく下から煽って、かき解すように上下に浮沈させるといった効果的な洗浄を行なうことができる。
また、洗浄水槽内に着脱可能に装着される洗浄カゴを備えることで、野菜等の洗浄対象食品を洗浄カゴに収容した状態で洗浄することができるため、洗浄対象食品の投入作業や取り出し作業等の取り扱いを容易にさせて能率よく作業を行なうことができるし、作業者の労力負担を軽減させることができる。
この噴射ストレーナを使用した食品洗浄装置（請求項１）は、被洗浄食品として比重の軽い葉物野菜等の洗浄に有効である。 Accordingly, it is possible to perform effective cleaning such that the food to be cleaned is entirely evenly crushed from the bottom and floated up and down so as to be broken.
In addition, by providing a washing basket that is detachably mounted in the washing water tank, it is possible to wash the food to be washed such as vegetables in the washing basket. It is possible to make the handling easy and work efficiently, and to reduce the labor burden on the operator.
The food washing apparatus using the spray strainer (Claim 1) is effective for washing leafy vegetables having a light specific gravity as a food to be washed.

特に、洗浄水槽の底面を逆錐形底面に形成させ、その中央部から噴射ストレーナによって含気水を噴射させるため（請求項２）、逆錐形底面が噴射方向のガイドとして機能し、含気水の飛散方向を安定させることができる。これにより、含気水の不規則方向への飛散を防止して含気水を効果的に被洗浄食品に浴びせることができる。 In particular, since the bottom surface of the washing water tank is formed into an inverted conical bottom surface, and the aerated water is injected from the central portion thereof by an injection strainer (Claim 2), the inverted conical bottom surface functions as a guide in the injection direction. The direction of water scattering can be stabilized. Thereby, scattering of the aerated water in irregular directions can be prevented, and the aerated water can be effectively bathed in the food to be cleaned.

また、圧力水管の途中に曝気用泡発生装置を設けた含気水噴射装置を備えているため、従来と異なり、空気噴出装置と給水装置とを別々に設ける必要がなく、コスト、メンテナンス、コンパクト化の面で有利になる。
また、空気噴出装置を構成する曝気用ブロアが不要になるため、省エネになるし、騒音による作業環境の悪化を解消できる。 In addition, since it is equipped with an aerated water injection device with an aeration bubble generator in the middle of the pressure water pipe, unlike the conventional case, there is no need to separately provide an air blowing device and a water supply device. This is advantageous in terms of conversion.
Further, since the aeration blower constituting the air jetting device is not required, energy saving is achieved, and deterioration of the work environment due to noise can be eliminated.

また、洗浄に伴って洗浄水の水面部分に浮き上がったゴミ等は洗浄水と共にオーバーフロー縁をオーバーフローして濾過水槽内に流入し、ここで濾過されてゴミ等が除去される。
このように、オーバーフロー縁を設けたことによってゴミ等を含む洗浄水を濾過水槽内に導入させて確実に濾過させることができる。 Further, the dust and the like floating on the surface of the cleaning water accompanying the cleaning overflows the overflow edge together with the cleaning water and flows into the filtered water tank, where it is filtered to remove the dust and the like.
Thus, by providing the overflow edge, it is possible to introduce the cleaning water containing dust and the like into the filtered water tank and reliably filter it.

特に、オーバーフロー縁を洗浄水槽の上端縁の全縁に亘って形成させたので（請求項３）、洗浄水槽のどこからでもオーバーフローさせることができ、ゴミ等を含む洗浄水がオーバーフローできずに滞留してしまうといったことがない。
また、集水口の開口幅を洗浄水槽の直径よりも幅広に形成させたので（請求項３）、
集水面積を広くとることができ、ゴミ等を含む洗浄水の流れをスムーズさせて、確実に濾過水槽に流入させることができる。 In particular, since the overflow edge is formed over the entire upper edge of the washing water tank (Claim 3), it can be overflowed from anywhere in the washing water tank, and the washing water containing dust etc. stays without overflowing. There is no such thing.
Moreover, since the opening width of the water collecting port is formed wider than the diameter of the washing water tank (Claim 3),
The water collection area can be increased, and the flow of cleaning water containing dust and the like can be made smooth to reliably flow into the filtered water tank.

また、本発明の食品洗浄装置（請求項４）では、含気水噴射装置の曝気用泡発生装置が、水噴射ノズルから絞り管内に向けて噴射させた水の勢いにより空気取り込み口から空気を取り込んで含気させるように形成されている。
従って、駆動装置としては循環ポンプだけで済み、その構造が簡単になるし、コスト、メンテナンス、コンパクト、安全の各面で有利になる。 Further, in the food cleaning device of the present invention (Claim 4 ), the aeration foam generating device of the aerated water jetting device draws air from the air intake port by the momentum of the water jetted from the water jet nozzle into the throttle tube. It is formed so as to be taken in and aerated.
Therefore, only a circulation pump is required as a driving device, the structure is simplified, and it is advantageous in terms of cost, maintenance, compactness, and safety.

本発明の食品洗浄装置（請求項５）は、圧力水管の先端に上向きに開口した噴出口を形成させた構成と、洗浄カゴの底部スクリーンの中央部分に水流遮断部を形成させた構成に特徴がある。
このように、上向きに開口した噴出口を形成させることで強い噴出力を得ることができるし、水流遮断部を形成させることで含気水による気泡と水流を洗浄水槽の全体に亘って均一に分散させることができ、この噴出口と水流遮断部との組み合わせによって、比重の重い被洗浄食品についても効果的な洗浄を行うことができる。 The food washing apparatus according to the present invention (Claim 5 ) is characterized by a structure in which an upwardly opening spout is formed at the tip of the pressure water pipe and a structure in which a water flow blocking part is formed in the central portion of the bottom screen of the washing basket. There is.
In this way, it is possible to obtain a strong jet power by forming a jet port that opens upward, and by forming a water flow blocking portion, bubbles and water flow due to the aerated water can be uniformly distributed over the entire washing water tank. It is possible to disperse, and effective cleaning can be performed even on foods to be cleaned that have a high specific gravity by combining the jet outlet and the water flow blocking unit.

図１、２、３で示す実施例１は請求項１に対応した食品洗浄装置で、機枠１上に洗浄水槽２と濾過水槽７が組み付けられている。
前記洗浄水槽２は、上面が開口し、底面が逆錐形底面（逆円錐底面）２１に形成された円形容器に形成されている。
実施例の洗浄水槽２は、底面が中央に向けて次第に縮小した逆円錐底面に形成された円形容器に形成されているが、これに限らず、角形容器に形成してもよく、この角形容器の逆錐形底面２１は、周囲が四角形で、中央部に向けて次第に円形になるように形成する。 The first embodiment shown in FIGS. 1, 2, and 3 is a food washing apparatus corresponding to claim 1, and a washing water tank 2 and a filtration water tank 7 are assembled on a machine frame 1.
The washing water tank 2 is formed in a circular container having an upper surface opened and a bottom surface formed in an inverted conical bottom surface (inverted conical bottom surface) 21.
The cleaning water tank 2 of the embodiment is formed in a circular container formed on an inverted conical bottom surface whose bottom surface is gradually reduced toward the center, but is not limited thereto, and may be formed in a rectangular container. The inverted conical bottom surface 21 is formed to have a quadrangular periphery and gradually become a circle toward the center.

この洗浄水槽２の上端縁はその全周がオーバーフロー縁２２に形成され、このオーバーフロー縁２２の全外周に外向きのフランジ面２０が形成され、このフランジ面２０に連続して前記洗浄水槽２の直径よりも幅広に開口した集水口２３が形成されている。 The upper end edge of the washing water tank 2 is formed at the overflow edge 22 on the entire periphery, and an outward flange surface 20 is formed on the entire outer periphery of the overflow edge 22. A water collection port 23 that is wider than the diameter is formed.

実施例では、洗浄水槽２の半周部分に一定幅の円弧状フランジ面２０ａを形成させ、洗浄水槽２の他方の半周部分に前記円弧状フランジ部２０ａの両端から接線方向に延長して平行フランジ部２０ｂ，２０ｂを形成させ、この平行フランジ部２０ｂ，２０ｂの幅全体を集水口２３の幅として形成させている。これにより集水面積を広くとることができる。 In the embodiment, an arc-shaped flange surface 20a having a constant width is formed on the half-circumferential portion of the washing water tank 2, and the other half-circumferential portion of the washing water tank 2 is extended tangentially from both ends of the arc-shaped flange portion 20a. 20b and 20b are formed, and the entire width of the parallel flange portions 20b and 20b is formed as the width of the water collecting port 23. Thereby, a water collection area can be taken widely.

前記集水口２３は樋状流路２４に接続され、この樋状流路２４の底部に回収管２５が接続され、この回収管２５が前記濾過水槽７内に延長されている。
従って、洗浄水槽２のオーバーフロー縁２２を越流したオーバーフロー水（洗浄水）はフランジ面２０を流れて集水口２３に流入し、さらに樋状流路２４から回収管２５を経て前記濾過水槽７内に流入する。なお、図３では濾過水槽７の図示を省略している。 The water collection port 23 is connected to a bowl-shaped flow path 24, a recovery pipe 25 is connected to the bottom of the bowl-shaped flow path 24, and the recovery pipe 25 is extended into the filtered water tank 7.
Accordingly, the overflow water (wash water) that has overflowed the overflow edge 22 of the wash water tank 2 flows through the flange surface 20 and flows into the water collection port 23, and further passes from the bowl-shaped flow path 24 through the recovery pipe 25 to the filtered water tank 7. Flow into. In addition, illustration of the filtration water tank 7 is abbreviate | omitted in FIG.

前記洗浄水槽２の逆錐形底面２１の中央部（最底部）には底部室２９が形成され、この底部室２９に噴射ストレーナ６が配設されている。
なお、図において、符号３５は洗浄水槽用のドレン排水弁である。 A bottom chamber 29 is formed at the center (bottommost portion) of the inverted conical bottom surface 21 of the washing water tank 2, and the jet strainer 6 is disposed in the bottom chamber 29.
In the figure, reference numeral 35 denotes a drain drain valve for a washing water tank.

前記濾過水槽７は、前記洗浄水槽２のオーバーフロー縁２２からオーバーフローしたゴミ等を含む洗浄水を流入させて濾過させるもので、方形容器に形成されている。 The filtered water tank 7 is made to flow by washing water containing dust and the like overflowing from the overflow edge 22 of the washing water tank 2 and is formed in a rectangular container.

この濾過水槽７の内部には循環ポンプ８として水中ポンプが設置され、この循環ポンプ８により濾過水槽７内の洗浄水を含気水噴射装置５に圧送させる。この循環ポンプ８としては低圧ポンプを使用できる。
また、濾過水槽７には、洗浄作業の間は給水管７３により常に給水され、また、汚れた洗浄水はオーバーフロー孔７２から装置外に排出させるようになっている。
なお、図において、符号７０は濾過水槽用のドレン排水弁である。 Inside the filtered water tank 7, a submersible pump is installed as a circulation pump 8, and the washing water in the filtered water tank 7 is pumped to the aerated water injection device 5 by the circulation pump 8. As this circulation pump 8, a low-pressure pump can be used.
The filtered water tank 7 is always supplied with water by a water supply pipe 73 during the cleaning operation, and dirty cleaning water is discharged from the overflow hole 72 to the outside of the apparatus.
In the figure, reference numeral 70 denotes a drain drain valve for a filtered water tank.

前記回収管２５の濾過水槽７内での排出口２６には、濾過用メッシュ袋７１が着脱可能に取り付けられている。
この濾過用メッシュ袋７１は、綿、麻、合成樹脂材によるメッシュで形成され、その口部を前記排出口２６に被せて縛ることにより着脱可能に取り付けるようになっている。 A filtration mesh bag 71 is detachably attached to the discharge port 26 in the filtered water tank 7 of the recovery pipe 25.
The mesh bag 71 for filtration is formed of a mesh made of cotton, hemp, or synthetic resin material, and is detachably attached by covering and tying the mouth portion over the discharge port 26.

前記含気水噴射装置５は、濾過水槽７の洗浄水を圧送させるための循環ポンプ８と、この循環ポンプ８と前記洗浄水槽２の底部室２９との間に配管した圧力水管５１と、この圧力水管５１の先端に取り付けた噴射ストレーナ６と、圧力水管５１の途中に設けた曝気用泡発生装置４によって構成されている。 The aerated water injection device 5 includes a circulation pump 8 for pumping the wash water of the filtered water tank 7, a pressure water pipe 51 piped between the circulation pump 8 and the bottom chamber 29 of the wash water tank 2, The spray strainer 6 attached to the tip of the pressure water pipe 51 and the aeration bubble generating device 4 provided in the middle of the pressure water pipe 51 are configured.

前記圧力水管５１の先端は、平面視で洗浄水槽２の中央に位置した底部室２９内において上向きに開口するように配管されている。
圧力水管５１の先端に取り付けた噴射ストレーナ６は、上端に向けて若干小径に形成したテーパ筒形状に形成され、その上端面は閉塞され、その外周面に多数の縦長孔６０が形成され、この多数の縦長孔６０を通して含気水を噴出させることにより気泡と水流を洗浄水槽２の全体に亘って均一に分散させるようになっている。 The tip of the pressure water pipe 51 is piped so as to open upward in the bottom chamber 29 located in the center of the washing water tank 2 in plan view.
The spray strainer 6 attached to the tip of the pressure water pipe 51 is formed in a tapered cylindrical shape having a slightly smaller diameter toward the upper end, its upper end surface is closed, and a number of vertically elongated holes 60 are formed on its outer peripheral surface. Air bubbles and water flow are uniformly distributed over the entire washing water tank 2 by ejecting the aerated water through a large number of the longitudinally long holes 60.

また、洗浄水槽２の底面を逆錐形底面２１に形成させ、その中央から含気水を噴射させるため、逆錐形底面２１が噴射方向のガイドとして機能し、含気水の飛散方向を安定させることができ、洗浄水槽２の底面を平状面に形成したものと異なり含気水の不規則方向への飛散を防止でき、含気水を効果的に被洗浄食品に浴びせることができる。 Further, since the bottom surface of the washing water tank 2 is formed on the inverted conical bottom surface 21 and the aerated water is injected from the center thereof, the inverted conical bottom surface 21 functions as a guide for the injection direction, and the scattering direction of the aerated water is stabilized. Unlike the case where the bottom surface of the washing water tank 2 is formed into a flat surface, scattering of the aerated water in irregular directions can be prevented, and the aerated water can be effectively bathed in the food to be washed.

なお、被洗浄食品が比重の軽い葉物野菜等の場合、噴射ストレーナ６を取り付けずに、圧力水管５１の先端から含気水を直接噴射させた場合、水流が集中して勢いが強くなりすぎるため、被洗浄食品を傷めるおそれがあり、洗浄用曝気としては好ましくない。 When the food to be cleaned is a leafy vegetable having a specific gravity or the like, when the aerated water is directly sprayed from the tip of the pressure water pipe 51 without attaching the spray strainer 6, the water flow is concentrated and the momentum becomes too strong. Therefore, there is a risk of damaging the food to be cleaned, which is not preferable as cleaning aeration.

前記曝気用泡発生装置４は、円周方向に等間隔に配設した数個のカラー４１を介して上流側円板４２と下流側円板４３とを対向接続させることで、両円板４２，４３間に外周に開口して空気取り込み口４４を保持させ、かつ前記上流側円板４２に水噴射ノズル４５を取り付け、前記下流側円板４３にレジューサによって形成した絞り管４６を取り付けた構造になっている。この場合、洗浄水槽２内の水位Ｗが絞り管４６の絞り部分（小径部分）に概ね一致するように設置している。 The aeration foam generator 4 connects both the discs 42 by connecting the upstream disc 42 and the downstream disc 43 to each other through several collars 41 arranged at equal intervals in the circumferential direction. , 43 is opened to the outer periphery to hold the air intake port 44, the water injection nozzle 45 is attached to the upstream disk 42, and the throttle tube 46 formed by a reducer is attached to the downstream disk 43. It has become. In this case, the water level W in the washing water tank 2 is installed so as to substantially coincide with the throttle portion (small diameter portion) of the throttle pipe 46.

そして、前記循環ポンプ８により圧送させた洗浄水を水噴射ノズル４５から絞り管４６内に向けて噴射させることで、その洗浄水の勢いによる誘引作用で空気取り込み口４４から空気を取り込んで、洗浄水中に気泡を含ませるように形成されている。
なお、水噴射ノズル４５からの勢い、絞り管４６の絞り程度等は適宜に設定することになるが、特に、絞り管４６を絞り過ぎると洗浄水が逆流して空気取り込み口４４から溢れ出てしまうし、絞りが小さくストレートに近くなると気泡が大きくなり、洗浄用曝気としては不適であった。 Then, the cleaning water pumped by the circulation pump 8 is jetted from the water jet nozzle 45 into the throttle pipe 46, so that the air is taken in from the air intake port 44 by the attracting action of the washing water. It is formed so that bubbles are included in water.
The momentum from the water jet nozzle 45 and the degree of restriction of the throttle pipe 46 are set as appropriate. In particular, if the throttle pipe 46 is excessively throttled, the washing water flows backward and overflows from the air intake port 44. However, when the aperture is small and close to straight, the bubbles become large, which is not suitable for cleaning aeration.

本発明の食品洗浄装置は、通常は、洗浄水槽２内に着脱可能に装着される洗浄カゴ９を使用して洗浄する。 The food washing apparatus of the present invention is usually washed using a washing basket 9 that is detachably mounted in the washing water tank 2.

この洗浄カゴ９は、前記洗浄水槽２内に納まるような外径の円形カゴに形成され、筒状胴部９０の底部に底部スクリーン９２が設けられると共に、筒状胴部９０の上端にスクリーン筒部９３が設けられ、そのスクリーン筒部９３の上端に取っ手９４が取り付けられている。
この洗浄カゴ９は洗浄水槽２内に設けたリング状の底受け部材２７上に載置させることで、着脱可能に装着されるが、その装着状態で上端９５が洗浄水槽２のオーバーフロー縁２２に概ね一致するように形成されている。
なお、洗浄カゴ９の装着構造としては、前記した底受け部材２７を形成させる以外に、例えば、洗浄カゴ９の筒状胴部９０の外周面に止め部材（図４の符号９６で示す）を取り付け、この止め部材を洗浄水槽の上端縁で係止させるなど適宜に設計できる。 The cleaning basket 9 is formed in a circular basket having an outer diameter so as to be accommodated in the cleaning water tank 2, and a bottom screen 92 is provided at the bottom of the cylindrical body 90, and a screen cylinder is provided at the upper end of the cylindrical body 90. A portion 93 is provided, and a handle 94 is attached to the upper end of the screen tube portion 93.
The cleaning basket 9 is detachably mounted by being placed on a ring-shaped bottom receiving member 27 provided in the cleaning water tank 2, but the upper end 95 is attached to the overflow edge 22 of the cleaning water tank 2 in the mounted state. It is formed so as to substantially match.
In addition, as a mounting structure of the cleaning basket 9, in addition to forming the bottom receiving member 27 described above, for example, a stopper member (indicated by reference numeral 96 in FIG. 4) is provided on the outer peripheral surface of the cylindrical body 90 of the cleaning basket 9. It can be designed as appropriate, for example, by attaching and locking this stop member at the upper edge of the washing water tank.

なお、洗浄カゴ９の筒状胴部９０は、平板で形成しても良いし、パンチング板やメッシュ板等で形成しても良い。
実施例のスクリーン筒部９３は、多数の細棒を所定の間隔で傾斜させた櫛歯状スクリーンに形成されているが、図４で示すように多数の細棒を所定の間隔で垂直方向に並設させたり、水平方向に並設させたり、格子状に形成させてもよい。
また、スクリーン筒部９３は、櫛歯状スクリーンに限らず、多数のパンチング孔を形成した透孔スクリーンやメッシュスクリーンや金網等で形成しても良い。この場合、櫛歯の間隔、パンチング孔の孔径、メッシュの大きさ等は洗浄対象となる食品の種類等に応じて適宜に決定する。
また、底部スクリーン９２についても、多数のパンチング孔（図４の符号９７で示す）を形成した透孔スクリーンやメッシュスクリーンや金網等で形成できる。 The cylindrical body portion 90 of the cleaning basket 9 may be formed of a flat plate, a punching plate, a mesh plate, or the like.
The screen tube portion 93 of the embodiment is formed as a comb-like screen in which a large number of thin bars are inclined at a predetermined interval. However, as shown in FIG. 4, a large number of thin bars are vertically arranged at a predetermined interval. They may be arranged side by side, arranged side by side in the horizontal direction, or formed in a lattice shape.
Further, the screen cylinder 93 is not limited to the comb-shaped screen, and may be formed of a through-hole screen, a mesh screen, a wire net, or the like in which a number of punching holes are formed. In this case, the interval between the comb teeth, the diameter of the punching holes, the size of the mesh, and the like are appropriately determined according to the type of food to be cleaned.
Further, the bottom screen 92 can also be formed of a through-hole screen, a mesh screen, a wire net, or the like in which a large number of punching holes (indicated by reference numeral 97 in FIG. 4) are formed.

従って、本実施例の食品洗浄装置では、洗浄カゴ９を使用して洗浄する場合、この洗浄カゴ９内に被洗浄食品を収容させて洗浄水槽２内に沈め、底受け部材２７上に載置させる。
そして、循環ポンプ８を作動させて、濾過水槽７内の洗浄水を圧力水管５１で圧送させながら途中に設けた曝気用泡発生装置４で気泡を含気させ、その含気水を洗浄水槽２の底部から噴射させるもので、このとき圧力水管５１の先端に噴射ストレーナ６を取り付けているため、気泡と水流を洗浄水槽２の全体に亘って均一に分散させるように噴射させることができる。 Therefore, in the food washing apparatus of this embodiment, when washing is performed using the washing basket 9, the food to be washed is accommodated in the washing basket 9 and submerged in the washing water tank 2 and placed on the bottom receiving member 27. Let
Then, the circulating pump 8 is operated, the bubbles are aerated by the aeration bubble generator 4 provided in the middle while the washing water in the filtered water tank 7 is pumped by the pressure water pipe 51, and the aerated water is washed into the washing water tank 2. Since the spray strainer 6 is attached to the tip of the pressure water pipe 51 at this time, the bubbles and the water flow can be sprayed so as to be uniformly distributed over the entire washing water tank 2.

また、洗浄に伴って洗浄水の水面部分に浮き上がったゴミ等、及び水中に浮遊するゴミ等は洗浄水と共に濾過水槽７内に流入していくもので、このとき、濾過用メッシュ袋７１内に流入してゴミ等が除去される。
そして、濾過された濾過水槽７内の洗浄水は循環ポンプ８により圧力水管５１に圧送され、含気水噴射装置５を経て洗浄水槽２内に噴射され、これを繰り返すことで食品を洗浄させていくことができる。 In addition, the dust that floats on the surface of the cleaning water along with the cleaning, and the dust that floats in the water flow into the filtered water tank 7 together with the cleaning water. Inflow and dust etc. are removed.
Then, the filtered washing water in the filtered water tank 7 is pumped to the pressure water pipe 51 by the circulation pump 8 and injected into the washing water tank 2 through the aerated water injection device 5, and the food is washed by repeating this. I can go.

この場合、洗浄作業に際し、循環ポンプ８の作動スイッチを入れると、同時に洗浄時間を設定したタイマ（図示せず）が作動し、このタイマによる設定時間になると、循環ポンプ８の作動スイッチが切れ、洗浄が終了するように制御されている。
なお、図２において、符号１５は制御ボックスである。 In this case, when the operation switch of the circulation pump 8 is turned on during the cleaning operation, a timer (not shown) that sets the cleaning time is activated at the same time. When the time set by this timer is reached, the operation switch of the circulation pump 8 is turned off, It is controlled so that the cleaning is completed.
In FIG. 2, reference numeral 15 denotes a control box.

このようにして洗浄が終了すると、洗浄カゴ９を洗浄水槽２から引き上げ、内部の洗浄済み食品を所定に取り出すことで１回の洗浄サイクルが終了する。 When the cleaning is completed in this way, the cleaning basket 9 is lifted from the cleaning water tank 2, and the internal cleaned food is taken out in a predetermined manner to complete one cleaning cycle.

本実施例では、洗浄カゴ９を備えない場合もあり、この場合には洗浄水槽２の底部に底部スクリーン部材（図示省略）を着脱可能に取り付けると共に、洗浄水槽２の上端縁（オーバーフロー縁）に筒状スクリーン（図示省略）を着脱可能に取り付けて、洗浄水槽２内に被洗浄食品を直接的に投入し、取り出すもので、その他は洗浄カゴ９を使用した前記動作と同様の動作で洗浄することができる。 In this embodiment, the cleaning basket 9 may not be provided. In this case, a bottom screen member (not shown) is detachably attached to the bottom of the cleaning water tank 2 and is attached to the upper edge (overflow edge) of the cleaning water tank 2. A cylindrical screen (not shown) is detachably attached, and the food to be cleaned is directly put into and taken out from the cleaning water tank 2, and the rest is cleaned by the same operation as the operation using the cleaning basket 9. be able to.

次に、図４に示す実施例２について説明する。
この実施例２は、実施例１で使用した噴射ストレーナ６を使用せずに圧力水管５１の先端に上向きに開口した噴出口５５を形成させた構成と、洗浄カゴ９の底部スクリーン９２の中央部分に平板による水流遮断部９２ａを形成させた構成に特徴があり、その他の構成は実施例１と同様である。 Next, Example 2 shown in FIG. 4 will be described.
In the second embodiment, the jet nozzle 55 used in the first embodiment is not used but the jet port 55 opened upward is formed at the tip of the pressure water pipe 51, and the central portion of the bottom screen 92 of the washing basket 9 is formed. The feature is that the flat water flow blocking portion 92a is formed, and the other configuration is the same as that of the first embodiment.

被洗浄食品が比重の重いニンニク、塩蔵キュウリ、ジャガイモ、生姜、小肉片、カット大根、カット人参などの場合、前記した噴射ストレーナ６を使用すると、この噴射ストレーナ６が抵抗となって噴出力が弱められ、その結果、洗浄力が低下することがある。
そこで、噴出力の抵抗となる噴射ストレーナ６を使用せずに、圧力水管５１の先端に上向きに開口した噴出口５５を形成させることにより、強い噴出力を得ることができる。 In the case of garlic, salted cucumbers, potatoes, ginger, small meat pieces, cut radishes, cut carrots, etc., where the food to be cleaned has a high specific gravity, if the above-described spray strainer 6 is used, this spray strainer 6 becomes resistance and the jet power is weakened. As a result, the detergency may be reduced.
Therefore, a strong jet output can be obtained by forming the jet outlet 55 that opens upward at the tip of the pressure water pipe 51 without using the jet strainer 6 that becomes the resistance of the jet output.

また、圧力水管５１の先端に上向きに開口した噴出口５５を形成させただけでは、上向きに含気水の主流が生じるため、含気水による気泡と水流を洗浄水槽２の全体に亘って均一に分散させることが困難になる。
そこで、洗浄カゴ９の底部スクリーン９２の中央部分に水流遮断部９２ａを形成させ、上向きに流動する含気水の主流を前記水流遮断部９２ａにより遮ることで、放射状の水流を生じさせ、これにより含気水による気泡と水流を洗浄水槽２の全体に亘って均一に分散させることができる。 Moreover, since the main flow of the aerated water is generated only by forming the jet port 55 opened upward at the tip of the pressure water pipe 51, the bubbles and the water flow of the aerated water are uniformly distributed over the entire washing water tank 2. It becomes difficult to disperse into.
Therefore, a water flow blocking portion 92a is formed at the central portion of the bottom screen 92 of the washing basket 9, and the main flow of the aerated water flowing upward is blocked by the water flow blocking portion 92a, thereby generating a radial water flow. Air bubbles and water flow due to the aerated water can be uniformly dispersed throughout the washing water tank 2.

このように、上向きに開口した噴出口５５を形成させて強い噴出力を得ることと、水流遮断部９２ａを形成させて含気水による気泡と水流を洗浄水槽２の全体に亘って均一に分散させることとの組み合わせによって、比重の重い被洗浄食品についても効果的な洗浄を行うことができる。 In this way, the jet port 55 opened upward is formed to obtain a strong jet power, and the water flow blocking portion 92a is formed to uniformly disperse bubbles and water flow by the aerated water over the entire washing water tank 2. In combination with this, it is possible to perform effective cleaning even for food to be cleaned having a high specific gravity.
