本発明は、一群の食品トレイが搭載されたカートを収納した状態で、食品トレイ上の食品に対して冷却処理あるいは加熱処理を行うカート棚式の食品加工装置に関する。 The present invention relates to a cart shelf type food processing apparatus that performs cooling treatment or heat treatment on food on a food tray in a state where a cart on which a group of food trays is mounted is stored.

この種の食品加工装置において、一群の食品トレイが搭載されたカートを庫内に収容して、カートごと冷却処理や加熱処理を行うことは、例えば、特許文献１に記載の貯蔵庫に公知である。そこでは、前面が開口する収納室を備えた貯蔵庫本体と、庫内空気を冷却ないし加熱する運転機構部と、収納室を開閉する扉などで貯蔵庫を構成している。庫内に収容されるカートは、基台と、基台に立設される一対の支柱と、各支柱の間に形成される多段状の棚などで構成されており、各棚に食品が盛り付けられたトレイを載置することができる。カートを貯蔵庫に収容した状態では、棚部分が収納室に収容され、基台は収納室の底壁と床面との間の空間に収まっている。この状態で扉を閉止することにより、収納室を閉止して食品の冷却処理や加熱処理を行うことができる。カートを貯蔵庫本体に収容した状態において、支柱の基台側の基端部分が接当干渉するのを防ぐために、収納室の底壁の前縁には先の基端部分を受入れる切欠が形成されている。 In this type of food processing apparatus, it is known, for example, in the storage described in Patent Document 1, that a cart on which a group of food trays is mounted is housed in a refrigerator and the entire cart is cooled or heat-treated. .. There, the storage is composed of a storage main body having a storage room with an open front, an operation mechanism for cooling or heating the air inside the storage, a door for opening and closing the storage room, and the like. The cart housed in the refrigerator is composed of a base, a pair of columns erected on the base, and a multi-tiered shelf formed between the columns, and food is served on each shelf. The tray can be placed. When the cart is housed in the storage, the shelves are housed in the storage room, and the base is housed in the space between the bottom wall and the floor of the storage room. By closing the door in this state, the storage chamber can be closed to cool or heat the food. When the cart is housed in the storage body, a notch is formed on the leading edge of the bottom wall of the storage chamber to receive the tip end portion in order to prevent the base end portion on the base side of the support column from contacting and interfering with each other. ing.

この種の食品加工装置は定期的に収納室内を洗浄装置で洗浄し、収納室の周囲壁に付着した食材の断片や煮汁などを洗い流して、収納室内を衛生的な状態に保持する必要がある。本出願人は、洗浄装置を備えた食品加工装置を先に提案しているが（特許文献２）、この食品加工装置はカートごと出し入れを行う装置ではなく、食品トレイを人手で収納室内の棚に出し入れする。 In this type of food processing equipment, it is necessary to regularly clean the storage room with a washing device to wash away food fragments and broth adhering to the surrounding walls of the storage room to keep the storage room in a hygienic condition. .. The applicant has previously proposed a food processing device equipped with a cleaning device (Patent Document 2), but this food processing device is not a device for loading and unloading the entire cart, but a shelf in the storage room for manually storing food trays. Put in and out.

また、本出願人はドアが開放された状態であることをドアスイッチで検知し、ドアスイッチがオン状態に切換った場合に庫内灯が点灯されるようにした冷蔵庫を先に提案している（特許文献３）。 In addition, the applicant first proposed a refrigerator in which the door switch detects that the door is open and the interior light is turned on when the door switch is switched to the on state. (Patent Document 3).

洗浄装置を備えたカート棚式の食品加工装置において収納室内の洗浄を行う場合には、カートを貯蔵庫本体から分離し、扉を閉じた状態で洗浄水を散布して、食材の断片などを洗い流す。しかし、カート棚式の食品加工装置の場合には、扉を閉じているにも拘らず、収納室の底壁の前縁に設けられた切欠を塞ぐことができないため、洗浄水の一部が底壁前端の切欠から床面に流下して、床面を汚損することがある。また、カートを収納室に収容するのに備えて予冷運転や予熱運転を行う場合に、収納室内の冷気や暖気が先の切欠部分から漏れ出る不具合もある。 When cleaning the storage room in a cart shelf-type food processing device equipped with a washing device, separate the cart from the storage body and spray washing water with the door closed to wash away food fragments. .. However, in the case of a cart shelf type food processing device, even though the door is closed, the notch provided in the leading edge of the bottom wall of the storage room cannot be closed, so that a part of the washing water is partially used. It may flow down to the floor surface from the notch at the front end of the bottom wall and stain the floor surface. Further, when the pre-cooling operation or the preheating operation is performed in preparation for accommodating the cart in the storage chamber, there is a problem that the cold air or warm air in the storage chamber leaks from the notch portion.

本発明の目的は、収納庫の洗浄時に洗浄水の一部が床面へ流下して、床面が洗浄水で汚損されるのを解消でき、従って、常に衛生的な状態で収納庫の洗浄を行えるカート棚式の食品加工装置を提供することにある。 An object of the present invention is to prevent a part of the washing water from flowing down to the floor surface during cleaning of the storage and the floor surface being contaminated with the washing water. Therefore, the storage is always cleaned in a hygienic state. The purpose is to provide a cart shelf type food processing device capable of performing the above.

本発明は、前面に開口を有する収納庫３と、収納庫３の前面の開口を揺動開閉するドア１１とを備え、一群の食品トレイ４０が搭載されたカート２を収納庫３内に収容して、カート２ごと冷却処理や加熱処理を行うカート棚式の食品加工装置を対象とする。食品加工装置は、収納庫３内に冷気あるいは暖気を供給する処理空気供給装置４と、収納庫３に洗浄水を送給する洗浄構造５と、これら両者４・５の作動状態を制御する制御部１０とを備える。カート２のトレイ収容部３７を収納庫３に収容した状態において、カート２のフレーム部３６の一部を受入れる切欠１６が、収納庫３の底壁３ａの前部に形成されている。収納庫３に、前記切欠１６を収納庫３の内面側から覆って、洗浄水が切欠１６へ流下するのを防止する遮蔽体６５を備えた遮水構造６４が設けられている。遮蔽体６５は、切欠１６を庫内側から覆う遮蔽位置と、庫内におけるカート２の移動軌跡の外へ退避する退避位置とに変位可能に構成されている。遮蔽体６５が遮蔽位置に変位されたことを検知して、検知信号を制御部１０に出力するセンサー７５が収納庫３に配置されている。そして、センサー７５から制御部１０へ検知信号が出力され、かつ洗浄構造５のスタートスイッチがオン操作された状態でのみ、洗浄構造５が制御部１０で起動されて洗浄作業を行うように構成されていることを特徴とする。 The present invention includes a storage cabinet 3 having an opening on the front surface and a door 11 that swings open and closes the opening on the front surface of the storage cabinet 3, and accommodates a cart 2 on which a group of food trays 40 is mounted in the storage cabinet 3. Then, the target is a cart shelf type food processing device that performs cooling treatment and heat treatment together with the cart 2. The food processing device controls the operating state of the processing air supply device 4 that supplies cold air or warm air into the storage 3, the cleaning structure 5 that supplies cleaning water to the storage 3, and both of these 4 and 5. A unit 10 is provided. In a state where the tray accommodating portion 37 of the cart 2 is accommodated in the storage 3, a notch 16 for receiving a part of the frame portion 36 of the cart 2 is formed in the front portion of the bottom wall 3a of the storage 3. The storage 3 is provided with a water-impervious structure 64 provided with a shield 65 that covers the notch 16 from the inner surface side of the storage 3 and prevents the washing water from flowing down into the notch 16. The shield 65 is configured to be displaceable at a shield position that covers the notch 16 from the inside of the refrigerator and a retracted position that retracts out of the movement locus of the cart 2 in the refrigerator. A sensor 75 that detects that the shield 65 has been displaced to the shield position and outputs a detection signal to the control unit 10 is arranged in the storage 3. Then, only when the detection signal is output from the sensor 75 to the control unit 10 and the start switch of the cleaning structure 5 is turned on, the cleaning structure 5 is activated by the control unit 10 to perform the cleaning operation. It is characterized by being.

収納庫３の底壁３ａの前部に立設した前壁１５に、カート２のフレーム部３６の出し入れを許す切欠１６が凹み形成されている。遮蔽体６５は、収納庫３に設けたヒンジ６６で遮蔽位置と退避位置の間で往復移動可能に支持されている。遮蔽位置における遮蔽体６５を移動不能に位置保持する位置保持具６７と、センサー７５は前記前壁１５に配置されており、遮蔽位置における遮蔽体６５と正対している。遮蔽体６５が遮蔽位置へ切換るときの移動動作によって、センサー７５がオン状態に切換って、遮蔽体６５が位置保持具６７で位置保持される。 A notch 16 that allows the frame portion 36 of the cart 2 to be taken in and out is formed in a recess in the front wall 15 that stands on the front portion of the bottom wall 3a of the storage 3. The shield 65 is supported by a hinge 66 provided in the storage 3 so as to be reciprocally movable between the shield position and the retracted position. The position holder 67 that holds the shield 65 in the shield position immovably and the sensor 75 are arranged on the front wall 15 and face the shield 65 in the shield position. The movement operation when the shield 65 switches to the shield position causes the sensor 75 to switch to the ON state, and the shield 65 is held in position by the position holder 67.

遮蔽体６５は遮蔽ばね６８で遮蔽位置へ向かって移動付勢されている。カート２が収納庫３から離脱するのに追随して、遮蔽体６５が遮蔽ばね６８の付勢力を受けて退避位置から遮蔽位置へ向かって揺動移動して、センサー７５をオン状態に切換え操作する。 The shield 65 is moved and urged toward the shield position by the shield spring 68. Following the removal of the cart 2 from the storage 3, the shield 65 receives the urging force of the shield spring 68 and swings from the retracted position to the shield position to switch the sensor 75 to the ON state. do.

遮蔽体６５の一側端と前壁１５がヒンジ６６を介して連結されて、遮蔽体６５の全体が前後揺動可能に支持されている。センサー７５は前壁１５の後面に配置されて、遮蔽位置における遮蔽体６５の板面と正対している。遮蔽位置における遮蔽体６５は、切欠１６の上開口と、内開口およびセンサー７５を収納庫３の側から覆っている。 One side end of the shield 65 and the front wall 15 are connected via a hinge 66, and the entire shield 65 is supported so as to be swingable back and forth. The sensor 75 is arranged on the rear surface of the front wall 15 and faces the plate surface of the shield 65 at the shield position. The shield 65 at the shield position covers the upper opening of the notch 16, the inner opening, and the sensor 75 from the side of the storage 3.

遮蔽体６５の下端と前壁１５がヒンジ６６を介して連結されて、遮蔽体６５の全体が前後傾動可能に支持されている。センサー７５は前壁１５の上面に配置されて、遮蔽位置における遮蔽体６５の板面と正対している。遮蔽位置における遮蔽体６５はヒンジ６６の上側へ起立して、切欠１６の上開口と、内開口およびセンサー７５を収納庫３の側から覆っている。 The lower end of the shield 65 and the front wall 15 are connected via a hinge 66, and the entire shield 65 is supported so as to be tiltable back and forth. The sensor 75 is arranged on the upper surface of the front wall 15 and faces the plate surface of the shield 65 at the shield position. The shield 65 at the shield position stands above the hinge 66 and covers the upper opening of the notch 16, the inner opening, and the sensor 75 from the side of the storage 3.

遮蔽体６５は、切欠１６を覆う下カバー７１と、下カバー７１に固定されてドア１１の後面壁６３と対向する上カバー７０と、上カバー７０の上部に設けられドア１１の後面壁６３に密着する止水パッキン７２を備えている。下カバー７１は、遮蔽位置において切欠１６の上開口を覆う排水壁７１ａと、遮蔽位置において切欠１６の内開口およびセンサー７５を庫内側から覆う縦壁７１ｂを一体に備えている。排水壁７１ａは、ドア１１の後面壁６３より前方へ突出する状態で前向きに張り出されている。 The shield 65 is provided on the lower cover 71 that covers the notch 16, the upper cover 70 that is fixed to the lower cover 71 and faces the rear wall 63 of the door 11, and the rear wall 63 of the door 11 that is provided above the upper cover 70. It is provided with a waterproof packing 72 that adheres tightly. The lower cover 71 integrally includes a drain wall 71a that covers the upper opening of the notch 16 at the shielding position, and a vertical wall 71b that covers the inner opening of the notch 16 and the sensor 75 from the inside of the refrigerator at the shielding position. The drainage wall 71a projects forward in a state of projecting forward from the rear wall 63 of the door 11.

本発明に係るカート棚式の食品加工装置では、収納庫３の底壁３ａの前部の切欠１６を覆う遮蔽体６５を備えた遮水構造６４を設けた。この遮蔽体６５は、切欠１６を庫内側から覆う遮蔽位置と退避位置とに変位可能とした。このように、遮水構造６４を備えた食品加工装置によれば、収納庫３の内部を洗浄構造５で洗浄する際に、洗浄水が切欠１６へ浸入するのを遮蔽体６５で遮断し止水できる。 In the cart shelf type food processing apparatus according to the present invention, a water shielding structure 64 provided with a shielding body 65 covering a notch 16 at the front portion of the bottom wall 3a of the storage 3 is provided. The shield 65 can be displaced to a shield position and a retracted position that cover the notch 16 from the inside of the refrigerator. As described above, according to the food processing apparatus provided with the water-impervious structure 64, when the inside of the storage 3 is cleaned by the cleaning structure 5, the shielding body 65 blocks and stops the washing water from entering the notch 16. I can water.

また、遮蔽体６５が遮蔽位置に変位されたことを検知するセンサー７５を装置本体１に配置して、センサー７５から制御部１０へ検知信号が出力され、かつ洗浄構造５のスタートスイッチがオン操作された状態でのみ、洗浄構造５が制御部１０で起動されて洗浄作業を行えるようにした。従って、作業者のうっかりミスで、遮蔽体６５が退避位置に位置保持された状態のままで、洗浄構造５のスタートスイッチがオン操作されたとしても、洗浄構造５が起動することはない。従って、常に遮蔽体６５が遮蔽位置に変位された状態で洗浄構造５を作動させて、洗浄水が切欠１６から床面Ｆへ流下して床面Ｆが洗浄水で汚損されるのを解消でき、常に衛生的な状態で収納庫３内の洗浄を行うことができる。 Further, a sensor 75 for detecting that the shield 65 has been displaced to the shield position is arranged in the apparatus main body 1, a detection signal is output from the sensor 75 to the control unit 10, and the start switch of the cleaning structure 5 is turned on. The cleaning structure 5 is activated by the control unit 10 so that the cleaning operation can be performed only in this state. Therefore, even if the start switch of the cleaning structure 5 is turned on while the shield 65 is held in the retracted position due to an accidental mistake by the operator, the cleaning structure 5 will not be activated. Therefore, the cleaning structure 5 can be operated with the shielding body 65 always displaced to the shielding position, so that the cleaning water can be prevented from flowing down from the notch 16 to the floor surface F and the floor surface F being polluted by the cleaning water. , The inside of the storage 3 can be cleaned at all times in a hygienic state.

収納庫３の底壁３ａの前部に立設した前壁１５に、カート２のフレーム部３６の出し入れを許す切欠１６を凹み形成し、遮蔽体６５は、ヒンジ６６で遮蔽位置と退避位置の間で往復移動可能に支持するようにした。こうした遮水構造６４によれば、冷却処理や洗浄作業を行う際に、作業者が遮蔽体６５をヒンジ６６の周りに移動操作するだけで、遮蔽体６５を遮蔽位置と退避位置に適確に位置切換えすることができる。また、位置保持具６７とセンサー７５を前記前壁１５に配置して、遮蔽体６５が遮蔽位置へ切換えられるときの移動動作を利用してセンサー７５をオン状態に切換え、同時に遮蔽体６５を位置保持具６７で移動不能に位置保持できるようにした。従って、遮蔽位置へ切換った状態の遮蔽体６５が、外部の振動や洗浄水の流動作用を受けて退避位置側へ分離移動するのを確実に防止して、切欠１６の止水をさらに確実に行えるうえ、一旦オン状態に切換ったセンサー７５がオフ状態に切換ることがないので、洗浄作業を確実に行うことができる。 A notch 16 that allows the frame portion 36 of the cart 2 to be taken in and out is formed in the front wall 15 erected on the front portion of the bottom wall 3a of the storage 3, and the shield 65 is held at the shield position and the retracted position by the hinge 66. It is supported so that it can be moved back and forth between them. According to such a water-impervious structure 64, when the cooling process or the cleaning work is performed, the operator simply moves the shield body 65 around the hinge 66, and the shield body 65 is accurately set to the shield position and the retracted position. The position can be switched. Further, the position holder 67 and the sensor 75 are arranged on the front wall 15, and the sensor 75 is switched to the on state by utilizing the movement operation when the shield 65 is switched to the shield position, and the shield 65 is positioned at the same time. The position can be held immovably by the holder 67. Therefore, the shield 65 in the state of being switched to the shield position is surely prevented from being separated and moved to the retracted position side due to the external vibration and the flow action of the washing water, and the water stoppage of the notch 16 is further ensured. In addition, since the sensor 75 once switched to the on state does not switch to the off state, the cleaning work can be surely performed.

遮蔽体６５を遮蔽ばね６８で遮蔽位置へ向かって移動付勢して、カート２が収納庫３から離脱するのに追随して、遮蔽体６５が退避位置から遮蔽位置へ向かって揺動移動して、センサー７５をオン状態に切換え操作できるようにした。こうした遮水構造６４によれば、単にカート２を収納庫３から離脱操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力で退避位置から遮蔽位置へ移動できるので、作業者が遮蔽体６５を退避位置で位置保持具６７から分離して、遮蔽位置へ移動操作する手間を省くことができる。また、カート２を装置本体１から分離した洗浄作業時はもちろん、予冷運転や予熱運転を行う際には、切欠１６が遮蔽体６５で自動的に覆われるので、切欠１６から冷気漏れや暖気漏れ、あるいは外気流入が生じることを極力防いでエネルギーロスを減少できる。 The shield 65 is moved and urged by the shield spring 68 toward the shield position, and the shield 65 swings and moves from the retracted position to the shield position as the cart 2 separates from the storage 3. The sensor 75 can be switched to the on state. According to such a water-impervious structure 64, the shield 65 can be moved from the retracted position to the shield position by the urging force of the shield spring 68 by simply moving the cart 2 away from the storage 3, so that the operator can move the shield 65 from the retracted position to the shield position. Can be separated from the position holder 67 at the retracted position, and the trouble of moving to the shielded position can be saved. Further, since the notch 16 is automatically covered with the shield 65 not only during the cleaning work in which the cart 2 is separated from the apparatus main body 1 but also during the precooling operation and the preheating operation, cold air leakage and warm air leakage from the notch 16 Alternatively, energy loss can be reduced by preventing the inflow of outside air as much as possible.

遮蔽体６５は、その一側端に設けたヒンジ６６で前後揺動可能に支持した。また、センサー７５は前壁１５の後面に配置して、遮蔽位置における遮蔽体６５の板面と正対させるようにした。こうした遮水構造６４によれば、遮蔽位置における遮蔽体６５で、切欠１６の上開口と、内開口およびセンサー７５を収納庫３の側から覆うことができるので、洗浄水が切欠１６およびセンサー７５へ向かって流動するのを遮蔽体６５で確実に遮蔽し止水できる。また、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ移動操作できるので、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。 The shield 65 was supported by a hinge 66 provided at one end thereof so as to be swingable back and forth. Further, the sensor 75 is arranged on the rear surface of the front wall 15 so as to face the plate surface of the shield body 65 at the shield position. According to such a water-impervious structure 64, the upper opening of the notch 16 and the inner opening and the sensor 75 can be covered from the side of the storage 3 by the shielding body 65 at the shielding position, so that the washing water can be covered by the notch 16 and the sensor 75. The shield 65 can reliably shield the flow toward the water and stop the water. Further, since the shield 65 can be moved from the shield position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1, the operator can move the shield 65. It is possible to save the trouble of moving from the shielded position to the retracted position.

遮蔽体６５は、その下端に設けたヒンジ６６で前後傾動可能に支持した。また、センサー７５は前壁１５の上面に配置して、遮蔽位置における遮蔽体６５の板面と正対させるようにした。こうした遮水構造６４によれば、遮蔽位置における遮蔽体６５をヒンジ６６の上側へ起立させて、切欠１６の上開口と、内開口およびセンサー７５を収納庫３の側から覆うことができるので、洗浄水が切欠１６およびセンサー７５へ向かって流動するのを遮蔽体６５で確実に遮蔽し止水できる。また、上記の遮水構造６４と同様に、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ移動操作できるので、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。 The shield 65 was supported by a hinge 66 provided at the lower end thereof so as to be tilted back and forth. Further, the sensor 75 is arranged on the upper surface of the front wall 15 so as to face the plate surface of the shield 65 at the shield position. According to such a water-impervious structure 64, the shield 65 at the shield position can be erected above the hinge 66 to cover the upper opening, the inner opening, and the sensor 75 of the notch 16 from the side of the storage 3. The shield 65 can reliably shield the washing water from flowing toward the notch 16 and the sensor 75 to stop the water. Further, similarly to the above-mentioned water-shielding structure 64, the shield body 65 is moved from the shielded position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1. Therefore, it is possible to save the trouble of the operator moving the shield 65 from the shield position to the retracted position.

遮蔽体６５は、切欠１６を覆う下カバー７１と、下カバー７１に固定される上カバー７０と、上カバー７０の上部に設けられドア１１の後面壁６３に密着する止水パッキン７２を備えるようにした。また、下カバー７１は、切欠１６の上開口を覆う排水壁７１ａと、切欠１６の内開口およびセンサー７５を庫内側から覆う縦壁７１ｂを一体に備えるようにして、排水壁７１ａをドア１１の後面壁６３より前方へ突出する状態で前向きに張り出すようにした。こうした遮水構造６４によれば、何らかの異常で洗浄水が止水パッキン７２と後面壁６３の封止面を通過して流下してきたとしても、洗浄水を排水壁７１ａで止水して、その左右両端から収納庫３の底壁３ａへと流下でき、洗浄水が切欠１６やセンサー７５の近傍へ浸入するのをさらに確実に解消できる。従って、閉じた状態におけるドア１１の後面壁６３が切欠１６の上方に位置している場合であっても、洗浄水が切欠１６を介して床面Ｆへ流下するのを解消できる。 The shield 65 includes a lower cover 71 that covers the notch 16, an upper cover 70 that is fixed to the lower cover 71, and a waterproof packing 72 that is provided above the upper cover 70 and is in close contact with the rear wall 63 of the door 11. I made it. Further, the lower cover 71 integrally includes a drainage wall 71a that covers the upper opening of the notch 16 and a vertical wall 71b that covers the inner opening of the notch 16 and the sensor 75 from the inside of the refrigerator. The rear wall 63 is projected forward so as to project forward. According to such an impermeable structure 64, even if the cleaning water flows down through the sealing surface of the waterproof packing 72 and the rear wall 63 due to some abnormality, the cleaning water is stopped by the drain wall 71a and the cleaning water is stopped. It can flow down from both the left and right ends to the bottom wall 3a of the storage 3, and it is possible to more reliably eliminate the infiltration of the washing water into the vicinity of the notch 16 and the sensor 75. Therefore, even when the rear wall 63 of the door 11 in the closed state is located above the notch 16, it is possible to eliminate the washing water flowing down to the floor surface F through the notch 16.

上記の急速冷却庫では、食品に対する冷却処理に先立って予冷運転を行い、冷却庫本体１の収納庫３の内部を所定温度にまで冷却する。予冷運転におけるカート２は、冷却庫本体１から分離されて、収納庫３の開口面が右ドア１１で閉止されており、このときの切欠１６は右ドア１１に設けたシャッター４５で閉塞されている（図５参照）。従って、予冷運転時に庫内の冷気が切欠１６から流出し、あるいは外気が切欠１６から庫内に侵入するのを解消して、収納庫３内を効率良く所定温度に冷却することができる。 In the above-mentioned rapid cooling chamber, a precooling operation is performed prior to the cooling treatment of the food, and the inside of the storage chamber 3 of the cooling chamber main body 1 is cooled to a predetermined temperature. The cart 2 in the precooling operation is separated from the cooling cabinet main body 1, and the opening surface of the storage cabinet 3 is closed by the right door 11, and the notch 16 at this time is closed by the shutter 45 provided on the right door 11. (See Fig. 5). Therefore, it is possible to eliminate the cold air in the refrigerator from flowing out from the notch 16 or the outside air from entering the refrigerator through the notch 16 during the pre-cooling operation, and efficiently cool the inside of the storage 3 to a predetermined temperature.

予冷運転が終了すると、右ドア１１を開いた状態で、一群の食品トレイ４０が搭載されたカート２を収納庫３へ向かって押し込む。このとき、基台部３５がガイド枠１８で移動案内されるので、カート２のトレイ収容部３７を収納庫３内へ適正に押し込むことができる。切欠１６を介して収納庫３に進入したフレーム部３６は、収納庫３の底壁３ａの上方に浮き離れた状態で位置しており、基台部３５は格納空間１３内に位置している。また、フレーム部３６の縦枠部３６ａ側が前壁１５の前側にはみ出た状態で、閉塞板４１が封止パッキン１７に接当している。 When the precooling operation is completed, the cart 2 on which the group of food trays 40 is mounted is pushed toward the storage 3 with the right door 11 open. At this time, since the base portion 35 is moved and guided by the guide frame 18, the tray accommodating portion 37 of the cart 2 can be properly pushed into the storage 3. The frame portion 36 that has entered the storage 3 through the notch 16 is located above the bottom wall 3a of the storage 3 in a floating state, and the base portion 35 is located in the storage space 13. .. Further, the closing plate 41 is in contact with the sealing packing 17 in a state where the vertical frame portion 36a side of the frame portion 36 protrudes to the front side of the front wall 15.

カート２を冷却庫本体１内に収納した状態において、右ドア１１を閉じ操作すると、カート２の閉塞板４１を切欠１６の周縁の封止パッキン１７に圧接させて、切欠１６を閉塞板４１で閉塞することができる。同時に図６に示すように、ドアパッキン２９の下辺直線部が閉塞板４１の前面と封止パッキン１７に密着するので、収納庫３の気密性を確保することができる。また、右ドア１１を閉じ操作することにより、フレーム部３６の縦枠部３６ａ側がフレーム収容部３１に入り込んで、シャッター４５をキックばね４７の付勢力に抗して、図５に示す開姿勢に強制的に変位操作するので、右ドア１１を支障なく閉じることができる。この状態のカート２の前面はドア１１で覆い隠されるので、食品を冷却処理するときの急速冷却庫の外観をすっきりさせることができる。 When the right door 11 is closed while the cart 2 is housed in the cooler main body 1, the closing plate 41 of the cart 2 is pressed against the sealing packing 17 on the periphery of the notch 16 and the notch 16 is pressed by the closing plate 41. Can be blocked. At the same time, as shown in FIG. 6, since the straight portion on the lower side of the door packing 29 is in close contact with the front surface of the closing plate 41 and the sealing packing 17, the airtightness of the storage 3 can be ensured. Further, by closing the right door 11, the vertical frame portion 36a side of the frame portion 36 enters the frame accommodating portion 31, and the shutter 45 is brought into the open posture shown in FIG. 5 against the urging force of the kick spring 47. Since the displacement operation is forcibly performed, the right door 11 can be closed without any trouble. Since the front surface of the cart 2 in this state is covered with the door 11, the appearance of the rapid cooler when the food is cooled can be made clear.

右ドア１１を閉じたときの同ドア１１の後面壁６３は、切欠１６の真上に位置している。そのため、収納庫３の内部を洗浄する場合に、右ドア１１の後面壁６３に沿って流下する洗浄水が切欠１６へ流下し、床面Ｆへ流出するおそれがある。こうした洗浄水の流出を確実に防止するために、閉じた右ドア１１と収納庫３の底壁３ａの前部の間に、切欠１６を収納庫３の内面側から覆う遮水構造６４が設けられている。図４、図５、図８に示すように遮水構造６４は、切欠１６の上面および後面を庫内側から覆う遮蔽体６５と、遮蔽体６５を遮蔽位置と退避位置の間で前後揺動可能（往復移動可能）に支持するヒンジ６６と、遮蔽体６５を遮蔽位置と退避位置において移動不能に位置保持する位置保持具６７と、遮蔽体６５を遮蔽位置へ向かって移動付勢する遮蔽ばね６８とを備えている。 The rear wall 63 of the door 11 when the right door 11 is closed is located directly above the notch 16. Therefore, when cleaning the inside of the storage 3, the washing water flowing down along the rear wall 63 of the right door 11 may flow down to the notch 16 and flow out to the floor surface F. In order to reliably prevent such outflow of washing water, a water-impervious structure 64 is provided between the closed right door 11 and the front portion of the bottom wall 3a of the storage 3 to cover the notch 16 from the inner surface side of the storage 3.

遮蔽位置における遮蔽体６５は、図５示すように切欠１６の上開口および内開口を収納庫３の側から覆うので、ドア１１の内面に沿って流下し、あるいは収納庫３の内方から切欠１６へ向かって飛散する洗浄水を、遮蔽体６５で受け止めて底壁３ａへと流下させることができる。カート２を収納庫３内へ押し込み操作する際には、フレーム部３６の後端が遮蔽体６５に接当するので、遮蔽体６５はカート２の進入動作に連動して遮蔽位置から退避位置へ変位操作される。また、カート２のトレイ収容部３７が収納庫３内に完全に収まった状態では、遮蔽体６５は図９に示すようにカート２の侵入領域の右側方へ退避した状態で、位置保持具６７で位置保持される。従って、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。 As shown in FIG. 5, the shield 65 at the shield position covers the upper opening and the inner opening of the notch 16 from the side of the storage 3, so that the shield 65 flows down along the inner surface of the door 11 or is notched from the inside of the storage 3. The washing water scattered toward 16 can be received by the shield 65 and flowed down to the bottom wall 3a. When the cart 2 is pushed into the storage 3, the rear end of the frame portion 36 comes into contact with the shield 65, so that the shield 65 moves from the shield position to the retract position in conjunction with the approaching operation of the cart 2. It is displaced. Further, when the tray accommodating portion 37 of the cart 2 is completely housed in the storage 3, the shield 65 is retracted to the right side of the intrusion area of the cart 2 as shown in FIG. 9, and the position holder 67 The position is held by. Therefore, it is possible to save the time and effort for the operator to move the shield 65 from the shield position to the retracted position.

止水パッキン７２は、断面が中空Ｄ字状に形成されており、その円弧表面が右ドア１１の後面壁６３に密着して、右ドア１１に沿って流下する洗浄水を止水し、その左右両端から収納庫３の底壁３ａへと流下させる。下カバー７１の排水壁７１ａの前縁は、右ドア１１の後面壁６３より前方へ突出する状態で前向きに張り出し形成されている（図５参照）。従って、洗浄水が何らかの異常で止水パッキン７２と後面壁６３の封止面を通過して流下してきたとしても、洗浄水を排水壁７１ａで止水して、その左右両端から収納庫３の底壁３ａへと流下させることができる。さらに、裾壁７１ｃと切欠１６の後縁の間には、小さな隙間が確保してあるので、万が一洗浄水が切欠１６に達したとしても、先の隙間から底壁３ａへと流下させることができる。 The water blocking packing 72 has a hollow D-shaped cross section, and its arc surface is in close contact with the rear wall 63 of the right door 11 to stop the washing water flowing down along the right door 11 and stop the washing water. It flows down from both the left and right ends to the bottom wall 3a of the storage 3. The leading edge of the drainage wall 71a of the lower cover 71 is formed so as to project forward from the rear wall 63 of the right door 11 (see FIG. 5). Therefore, even if the cleaning water flows down through the sealing surface of the waterproof packing 72 and the rear wall 63 due to some abnormality, the cleaning water is stopped by the drain wall 71a and the storage 3 is stored from the left and right ends thereof. It can flow down to the bottom wall 3a. Further, since a small gap is secured between the hem wall 71c and the trailing edge of the notch 16, even if the washing water reaches the notch 16, it can flow down from the gap to the bottom wall 3a. can.

位置保持具６７は磁石で構成されており、遮蔽体６５の下カバー７１の縦壁７１ｂを遮蔽位置と退避位置において移動不能に位置保持する。そのために、前壁１５のピラー３０側の端部後面と、収納庫３の右内周面の後寄りの２個所に位置保持具６７を配置している。洗浄作業を行う場合には、退避位置に位置保持された遮蔽体６５を位置保持具６７から分離して、遮蔽位置へと戻す必要がある。このときの遮蔽体６５は、位置保持具６７から分離されるのと同時に、遮蔽ばね６８の付勢力を受けて遮蔽位置へ自動的に移動変位し、下カバー７１の縦壁７１ｂが前壁１５側の位置保持具６７で吸着保持されるので、遮蔽体６５を退避位置から遮蔽位置へ移動する手間を省くことができる。 The position holder 67 is composed of a magnet, and holds the vertical wall 71b of the lower cover 71 of the shield 65 in an immovable position at the shield position and the retracted position. For this purpose, the position holders 67 are arranged at two locations, the rear surface of the end portion of the front wall 15 on the pillar 30 side and the rear surface of the right inner peripheral surface of the storage 3. When performing the cleaning work, it is necessary to separate the shield 65 whose position is held at the retracted position from the position holder 67 and return it to the shield position. At this time, the shield 65 is separated from the position holder 67, and at the same time, is automatically moved and displaced to the shield position by receiving the urging force of the shield spring 68, and the vertical wall 71b of the lower cover 71 is the front wall 15. Since it is attracted and held by the position holder 67 on the side, it is possible to save the trouble of moving the shield 65 from the retracted position to the shield position.

また、磁石の磁気吸着作用で遮蔽体６５を遮蔽位置や退避位置に位置保持できるので、例えば位置保持具６７をラッチ構造などの機械的な保持構造で構成してある場合に比べて、位置保持具６７の構造の簡素化と低コスト化を同時に実現できる。さらに、遮蔽体６５が遮蔽位置へ切換えられるときの移動動作を利用して後述するセンサー７５をオン状態に切換え、同時に遮蔽体６５を位置保持具６７で移動不能に位置保持するので、遮蔽位置へ切換った状態の遮蔽体６５が、外部の振動や洗浄水の流動作用を受けて退避位置側へ分離移動するのを確実に防止して、切欠１６の止水をさらに確実に行える。また、一旦オン状態に切換ったセンサー７５がオフ状態に切換ることがないので、洗浄作業を確実に行うことができる。 Further, since the shield 65 can be held at the shield position or the retracted position by the magnetic attraction action of the magnet, the position is held as compared with the case where the position holder 67 is configured with a mechanical holding structure such as a latch structure, for example. The structure of the tool 67 can be simplified and the cost can be reduced at the same time. Further, the sensor 75, which will be described later, is switched to the ON state by utilizing the movement operation when the shield 65 is switched to the shield position, and at the same time, the shield 65 is held in the immovable position by the position holder 67, so that the shield 65 is moved to the shield position. The shield 65 in the switched state is surely prevented from being separated and moved to the retracted position side due to the external vibration and the flowing action of the washing water, so that the notch 16 can be stopped more reliably. Further, since the sensor 75 once switched to the on state does not switch to the off state, the cleaning work can be reliably performed.

遮蔽体６５が退避位置に位置保持された状態のままで、洗浄作業を行うと、洗浄水が切欠１６へと流れ落ち、その一部が床面Ｆへ流出するおそれがある。こうしたうっかりミスを解消するために、図８に示すように、遮蔽位置において遮蔽体６５対向する前壁１５に、遮蔽体６５が遮蔽位置へ切換ったことを検知するセンサー７５を配置している。センサー７５は市販されている防水型のスイッチ付きマグネットからなる。図１に示すように、センサー７５は、プラスチック製のハウジング７６の内部に永久磁石７７と、磁気スイッチ７８を封入して構成してあり、遮蔽体６５が遮蔽位置へ切換った状態において、磁気スイッチ７８がオン状態に切換って出力信号を制御部１０に出力する。制御部１０は、センサー７５からオン信号が出力され、さらに洗浄構造５のスタートスイッチ（図示していない）がオン操作された状態でのみ、洗浄構造５を起動させる。従って、遮蔽体６５が退避位置に位置保持された状態のままで洗浄構造５が作動するのを確実に防止できる。センサー７５の後面は、前壁１５の後面に固定した目隠しカバー７９で塞がれている。目隠しカバー７９は磁気吸着できないステンレス板材で形成される。 If the cleaning operation is performed while the shield 65 is held in the retracted position, the cleaning water may flow down to the notch 16 and a part of the cleaning water may flow out to the floor surface F. In order to eliminate such an inadvertent mistake, as shown in FIG. 8, a sensor 75 for detecting that the shield 65 has switched to the shield position is arranged on the front wall 15 facing the shield 65 at the shield position. .. The sensor 75 consists of a commercially available waterproof magnet with a switch. As shown in FIG. 1, the sensor 75 is configured by enclosing a permanent magnet 77 and a magnetic switch 78 inside a plastic housing 76, and is magnetic when the shield 65 is switched to the shield position. The switch 78 switches to the ON state and outputs an output signal to the control unit 10. The control unit 10 activates the cleaning structure 5 only when an ON signal is output from the sensor 75 and the start switch (not shown) of the cleaning structure 5 is turned ON. Therefore, it is possible to reliably prevent the cleaning structure 5 from operating while the shield 65 is held in the retracted position. The rear surface of the sensor 75 is closed with a blind cover 79 fixed to the rear surface of the front wall 15. The blind cover 79 is made of a stainless steel plate that cannot be magnetically attracted.

上記の食品加工装置によれば、作業者のうっかりミスで、遮蔽体６５が退避位置に位置保持された状態のままで、洗浄構造５のスタートスイッチがオン操作されたとしても、洗浄構造５が起動することはない。従って、常に遮蔽体６５が遮蔽位置に変位された状態で洗浄構造５を作動させて、洗浄水が切欠１６から床面Ｆへ流下して床面Ｆが洗浄水で汚損されるのを解消でき、常に衛生的な状態で収納庫３内の洗浄を行える。 According to the above-mentioned food processing apparatus, even if the start switch of the cleaning structure 5 is turned on while the shield 65 is held in the retracted position due to an accidental mistake by the operator, the cleaning structure 5 is operated. It never starts. Therefore, the cleaning structure 5 can be operated with the shielding body 65 always displaced to the shielding position, so that the cleaning water can be prevented from flowing down from the notch 16 to the floor surface F and the floor surface F being polluted by the cleaning water. , The inside of the storage 3 can be cleaned at all times in a hygienic state.

また、上記のカート棚式の急速冷却庫によれば、カート２を冷却庫本体１から分離し、右ドア１１を閉じて洗浄作業を行う状態では、切欠１６の上面および後面が遮蔽体６５で覆われ、さらに止水パッキン７２が右ドア１１の後面壁６３に密着する。従って、右ドア１１の後面壁６３に沿って流下する洗浄水が切欠１６に浸入するのを確実に防止して、洗浄水の一部が切欠１６から床面Ｆへ流下して、床面Ｆが洗浄水で汚損されるのを解消でき、常に衛生的な状態で収納庫３内の洗浄を行える。また、洗浄後には、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ移動操作できる。さらに、洗浄作業時はもちろん予冷運転を行う際にも、切欠１６がシャッター４５と遮蔽体６５で覆われるので、切欠１６から冷気漏れ、あるいは外気流入が生じることを防いでエネルギーロスを減少できる。 Further, according to the above-mentioned cart shelf type rapid cooling cabinet, in a state where the cart 2 is separated from the cooling cabinet main body 1 and the right door 11 is closed to perform cleaning work, the upper surface and the rear surface of the notch 16 are covered with a shield 65. It is covered and the waterproof packing 72 is in close contact with the rear wall 63 of the right door 11. Therefore, the washing water flowing down along the rear wall 63 of the right door 11 is surely prevented from entering the notch 16, and a part of the washing water flows down from the notch 16 to the floor surface F, so that the floor surface F Can be eliminated from being contaminated with washing water, and the inside of the storage 3 can be washed in a hygienic state at all times. Further, after cleaning, the shield 65 can be moved from the shield position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1. Further, since the notch 16 is covered with the shutter 45 and the shield 65 not only during the cleaning work but also during the precooling operation, it is possible to prevent cold air leakage or outside air inflow from the notch 16 and reduce energy loss.

遮蔽体６５をヒンジ６６で遮蔽位置と退避位置の間で往復移動可能に支持し、各位置において遮蔽体６５を位置保持具６７で移動不能に位置保持するので、冷却処理や洗浄作業を行う際には、遮蔽体６５を位置保持具６７から分離してヒンジ６６の周りに移動操作するだけで、遮蔽体６５を遮蔽位置と退避位置に適確に位置切換えすることができる。また、遮蔽位置においては、遮蔽体６５に設けた止水パッキン７２がドア１１の後面壁６３に密着するので、右ドア１１の後面壁６３に沿って流下する洗浄水が切欠１６に浸入するのを確実に防止できる。 The shield 65 is supported by the hinge 66 so as to be reciprocally movable between the shield position and the retracted position, and the shield 65 is held in an immovable position by the position holder 67 at each position. The shield 65 can be accurately switched between the shield position and the retracted position simply by separating the shield 65 from the position holder 67 and moving the shield 65 around the hinge 66. Further, at the shielding position, the waterproof packing 72 provided on the shielding body 65 is in close contact with the rear wall 63 of the door 11, so that the washing water flowing down along the rear wall 63 of the right door 11 enters the notch 16. Can be reliably prevented.

遮蔽体６５は、遮蔽位置においてのみ位置保持具６７で移動不能に位置保持することができる。その場合には、遮蔽体６５が遮蔽ばね６８で遮蔽位置へ向かって移動付勢してあるので、カート２が収納庫３から離脱するのに追随して、遮蔽体６５を退避位置から遮蔽位置へ向かって揺動移動させて、センサー７５をオン状態に切換え操作できる。こうした遮水構造６４によれば、単にカート２を収納庫３から離脱操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力で退避位置から遮蔽位置へ移動できるので、作業者が遮蔽体６５を退避位置で位置保持具６７から分離して、遮蔽位置へ移動させる手間を省くことができる。また、カート２を装置本体１から分離した洗浄作業時はもちろん、予冷運転を行う際には、切欠１６が遮蔽体６５で自動的に覆われるので、切欠１６から冷気漏れ、あるいは外気流入が生じることを極力防いでエネルギーロスを減少できる。 The shield 65 can be immovably held by the position holder 67 only at the shield position. In that case, since the shield 65 is moved and urged toward the shield position by the shield spring 68, the shield 65 is moved from the retracted position to the shield position following the removal of the cart 2 from the storage 3. The sensor 75 can be switched to the on state by swinging toward. According to such a water-impervious structure 64, the shield 65 can be moved from the retracted position to the shield position by the urging force of the shield spring 68 by simply moving the cart 2 away from the storage 3, so that the operator can move the shield 65 from the retracted position to the shield position. Can be separated from the position holder 67 at the retracted position and moved to the shielded position. Further, since the notch 16 is automatically covered with the shield 65 not only during the cleaning work in which the cart 2 is separated from the apparatus main body 1 but also during the precooling operation, cold air leaks or outside air flows in from the notch 16. You can prevent this as much as possible and reduce energy loss.

図１０は遮水構造６４の別の実施例を示している。そこでは、遮蔽体６５をその下端に設けたヒンジ６６で前後傾倒可能に支持して、遮蔽ばね６８で遮蔽位置へ向かって起立付勢するようにした。遮蔽体６５は、その裾壁７１ｃの左右に固定したにヒンジ６６で支持されている。また、前壁１５の上面にセンサー７５を埋設して、遮蔽体６５が退避姿勢から遮蔽姿勢に切換ったことをセンサー７５で検知できるようにした。センサー７５は、マイクロスイッチ８１と、遮蔽体６５が遮蔽姿勢に切換るときの動作をマイクロスイッチ８１に伝える受動ピン８２と、受動ピン８２を押し出し付勢するばね８３などで構成されている。 FIG. 10 shows another embodiment of the impermeable structure 64. There, the shield 65 was supported by a hinge 66 provided at the lower end thereof so as to be tilted back and forth, and the shield spring 68 was used to erect and urge the shield toward the shield position. The shield 65 is fixed to the left and right of the hem wall 71c and is supported by hinges 66. Further, a sensor 75 is embedded in the upper surface of the front wall 15 so that the sensor 75 can detect that the shield 65 has switched from the retracted posture to the shielded posture. The sensor 75 includes a micro switch 81, a passive pin 82 that transmits the operation when the shield 65 switches to the shield posture to the micro switch 81, a spring 83 that pushes out and urges the passive pin 82, and the like.

こうした遮水構造６４によれば、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ傾動操作できるので、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。また、洗浄作業時はもちろん予冷運転を行う際にも、切欠１６が遮蔽体６５で覆われるので、切欠１６から冷気漏れ、あるいは外気流入が生じることを極力防いでエネルギーロスを減少できる。さらに、フレーム部３６と収納庫３の底壁３ａの間の上下隙間を利用して、遮蔽体６５を退避させることができるので、遮蔽体６５を退避させるためのスペースを別途確保する必要がなく、その分だけ収納庫３の構造を簡素化できる。他は先の実施例と同じであるので、同じ部材に同じ符号を付してその説明を省略する。この実施例から理解できるように、センサー７５は遮蔽位置に切換った遮蔽体６５と正対する収納庫３の内周壁に設けてあればよく、必要があればピラー３０に設けてあってもよい。 According to such a water-impervious structure 64, the shield 65 can be tilted from the shield position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1. It is possible to save the trouble of the operator moving the shield 65 from the shield position to the retracted position. Further, since the notch 16 is covered with the shield 65 not only during the cleaning work but also during the precooling operation, it is possible to prevent cold air leakage or outside air inflow from the notch 16 as much as possible and reduce energy loss. Further, since the shield 65 can be retracted by using the vertical gap between the frame portion 36 and the bottom wall 3a of the storage 3, there is no need to separately secure a space for retracting the shield 65. Therefore, the structure of the storage 3 can be simplified accordingly. Since the other parts are the same as those in the previous embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted. As can be understood from this embodiment, the sensor 75 may be provided on the inner peripheral wall of the storage 3 facing the shield 65 switched to the shielding position, and may be provided on the pillar 30 if necessary. ..

上記の実施例以外に、遮水構造６４は左右一対の遮蔽体６５・６５と、各遮蔽体６５を前後揺動可能に支持するヒンジ６６・６２と。各遮蔽体６５を遮蔽位置へ向かって移動付勢する遮蔽ばね６８・６８などで構成することができる。その場合には、各遮蔽体６５に対応して一対のセンサー７５を設けておくとよい。カート２が装置本体１に対して押し込み操作されるとき、各遮蔽体６５・６５は遮蔽ばね６８・６８の付勢力に抗して遮蔽位置から退避位置へ観音開き状に移動操作される。切欠１６は、収納庫３の底壁３ａの前端に切欠き形成してあってもよい。シャッター構造４４は省略することができる。遮蔽体６５は、付勢ばね６８で退避位置へ向かって移動付勢してあってもよく、作業者が手動で遮蔽位置と退避位置に切換え操作する構造であってもよい。また、止水パッキン７２は、ドア１１の後面壁６３に固定してあってもよい。 In addition to the above embodiment, the water-impervious structure 64 includes a pair of left and right shields 65 and 65, and hinges 66 and 62 that support each shield 65 so as to swing back and forth. Each shielding body 65 can be composed of shielding springs 68, 68 or the like that move and urge the shielding body 65 toward the shielding position. In that case, it is preferable to provide a pair of sensors 75 corresponding to each shield 65. When the cart 2 is pushed against the device main body 1, each of the shields 65 and 65 is moved from the shield position to the retracted position in a double-door manner against the urging force of the shield springs 68 and 68. The notch 16 may be formed at the front end of the bottom wall 3a of the storage 3. The shutter structure 44 can be omitted. The shield 65 may be moved and urged toward the retracted position by the urging spring 68, or may have a structure in which the operator manually switches between the shield position and the retracted position. Further, the waterproof packing 72 may be fixed to the rear wall 63 of the door 11.

位置保持具６７は、磁石で構成する以外に、ラッチ構造や機械的に係脱する係止構造で構成してあってもよい。位置保持具６７は、遮蔽体６５を遮蔽位置へ向かって移動付勢する遮蔽ばね６８が兼ねることができる。その場合には、前壁１５に設けた位置保持具６７を省略してもよい。センサー７５はスイッチ付きマグネット以外に、近接スイッチ、光電スイッチ、マイクロスイッチ、リードスイッチなどのセンサーを適用できる。下カバー７１が磁気吸着不能なステンレス板材で形成してある場合には、磁石と対応する板面に鉄板製の吸着体を固定しておけばよい。本発明に係る食品加工装置は、実施例で説明した急速冷却庫に限られず、食品に対して加熱処理を行う加熱庫等にも適用できる。 The position holder 67 may have a latch structure or a locking structure that mechanically engages and disengages, in addition to the magnet. The position holder 67 can also serve as a shielding spring 68 that moves and urges the shielding body 65 toward the shielding position. In that case, the position holder 67 provided on the front wall 15 may be omitted. In addition to the magnet with a switch, the sensor 75 can apply a sensor such as a proximity switch, a photoelectric switch, a micro switch, or a reed switch. When the lower cover 71 is made of a stainless steel plate that cannot be magnetically attracted, an iron plate adsorbent may be fixed to the plate surface corresponding to the magnet. The food processing apparatus according to the present invention is not limited to the rapid cooling chamber described in the examples, but can also be applied to a heating chamber or the like that heat-treats food.
