図７あるいは特許文献１、２に示されるような従来の食鳥屠体の放血処理手段にあっては、該食鳥屠体がオーバーコンベア２によって放血処理室内を移動せしめられながら放血するため、該放血処理室内に食鳥屠体の血液や外皮の破片が飛散して放血処理室内が汚染されるとともに、衛生面でも良好な状態を保持できない。
また、かかる従来技術にあっては、放血処理後において放血処理室を洗浄する際には、放血処理室の外壁に蒸気あるいは水を噴出して、この蒸気あるいは水によって該放血処理室内の汚染物を洗い流すようになっているが、かかる蒸気あるいは水の併用では、特に血液や油脂分の完全洗浄が困難で、十分な洗浄効果が得られ難い。このため洗浄用の蒸気及び水の消費量も多くなる。 In the conventional blood release processing means of the poultry carcass as shown in FIG. 7 or Patent Documents 1 and 2, the poultry carcass discharges blood while being moved in the blood release processing chamber by the over conveyor 2, The blood of the poultry carcass and the debris of the outer skin are scattered in the blood release treatment chamber to contaminate the blood release treatment chamber, and the hygienic condition cannot be maintained.
Further, in this prior art, when the blood release treatment chamber is washed after the blood release treatment, steam or water is jetted to the outer wall of the blood release treatment chamber, and the vapor or water causes contaminants in the blood release treatment chamber. However, the combined use of such steam or water makes it difficult to completely clean blood and oil and fat, and it is difficult to obtain a sufficient cleaning effect. For this reason, consumption of steam and water for cleaning increases.

また、図６あるいは特許文献３に示されるような従来の食鳥屠体の脱毛前における温熱処理手段にあっては、食鳥屠体の温熱処理時及び温熱処理施行後の温熱処理槽内部の洗浄時に使用水蒸気が処理室内に漏洩して該処理室内の湿度が異常に上昇して、処理室内の衛生状態が悪化するとともに、処理室内湿度の異常上昇に伴う食鳥屠体の品質低下が発生し易い。
さらには、温熱処理槽０２１での使用水蒸気２３による多量の熱量を外部に放出するので、エネルギー効率が低下する。 Moreover, in the conventional heat treatment means before depilation of a poultry carcass as shown in FIG. 6 or Patent Document 3, the inside of the heat treatment tank inside the heat treatment of the poultry carcass and after the heat treatment is performed. Water vapor leaks into the processing chamber at the time of cleaning, and the humidity in the processing chamber rises abnormally. This deteriorates the hygienic condition in the processing chamber, and causes deterioration in the quality of the poultry carcass due to the abnormal increase in humidity in the processing chamber. Easy to do.
Furthermore, since a large amount of heat generated by the steam 23 used in the thermal heat treatment tank 021 is released to the outside, the energy efficiency is lowered.

従って、本発明はかかる従来技術の課題に鑑み、食肉屠体の放血処理時において食肉屠体の血液や外皮の破片の飛散による処理室内の汚染を回避して良好な衛生状態を保持し、処理室内の汚染物質の除去効果を向上せしめて洗浄時間を短縮するとともに洗浄用の蒸気及び水の消費量を低減し、さらには食肉屠体の温熱処理時において処理室内湿度の異常上昇に伴う食鳥屠体の品質低下を回避するとともに使用水蒸気の熱量を有効利用してエネルギー効率を向上可能とした食肉屠体の解体前処理方法及びその装置を提供することを目的とする。   Therefore, in view of the problems of the prior art, the present invention avoids contamination in the processing chamber due to the scattering of blood of the meat carcass and debris of the meat carcass at the time of exsanguination of the meat carcass, maintains a good hygiene condition, Poultry that improves the removal effect of indoor pollutants, shortens cleaning time, reduces consumption of steam and water for cleaning, and also causes abnormal increase in humidity in processing chamber during heat treatment of meat carcass An object of the present invention is to provide a meat carcass pretreatment method and apparatus for avoiding deterioration in carcass quality and improving energy efficiency by effectively using the amount of heat of steam used.

本発明はかかる目的を達成するもので、食肉屠体に初期切断、放血を含む前処理を施し、次いで脱毛前の温熱処理を施すようにした食肉屠体の解体前処理方法において、一部または全部が外部に開放可能な放血処理槽内で前記食肉屠体に前記前処理を施した後における該放血処理槽の洗浄処理として、該放血処理槽を閉鎖状態にして該放血処理槽内に蒸気を供給して該蒸気により放血処理槽の内部を洗浄する蒸気洗浄工程を施し、次いで該放血処理槽内に水を供給して該水により放血処理槽の内部を洗浄する水洗浄工程を施し、
更に前記放血処理槽の廃棄物排出通路に切換え手段を配置し、前記切換え手段による排出通路の切換えにより、前記蒸気洗浄工程後に該蒸気洗浄工程による油脂分、血液分等の一次廃棄物を一次廃棄物処理手段に搬出し、前記水洗浄工程後に該水洗浄工程による廃液を前記一次廃棄物処理手段に対して独立して配置された廃液処理手段に搬出することを特徴とする。 The present invention achieves such an object. In the method for pre-disassembling a meat carcass, the meat carcass is subjected to a pretreatment including initial cutting and exsanguination, and then a heat treatment before hair removal. As a cleaning process for the blood treatment tank after the pretreatment of the meat carcass in a blood release treatment tank that can be opened to the outside, the blood release treatment tank is closed and steam is released into the blood discharge treatment tank. the supplying subjected to steam cleaning step of cleaning the interior of the exsanguination process vessel by steam, then facilities a water washing step of washing the inside of exsanguination processing tank by the water by supplying water to dissipating blood treatment tank ,

It is carried out to a waste treatment means, and after the water washing step, waste liquid from the water washing step is carried out to a waste liquid treatment means arranged independently of the primary waste treatment means.

さらに本発明は、次のように構成する。
即ち、食肉屠体に初期切断、放血を含む前処理を施し、次いで脱毛前に該食肉屠体を温熱処理槽に導入し、該温熱処理槽内において該食肉屠体を蒸気によって加熱生成された温水により加熱する温熱処理を施すようにした食肉屠体の解体前処理方法において、前記温熱処理の施行後に前記温熱処理槽を水蒸気回収ダクトで覆って該温熱処理槽内を実質的な閉鎖空間に形成し、該温熱処理槽内に蒸気を供給して該蒸気により温熱処理槽の内部を洗浄し、該洗浄後の蒸気を前記水蒸気回収ダクト内を通して水蒸気回収管に回収することを特徴とする。 Furthermore, this invention is comprised as follows.
That is, the meat carcass was subjected to pretreatment including initial cutting and exsanguination, and then the meat carcass was introduced into a heat treatment tank before hair removal, and the meat carcass was generated by heating in the heat treatment tank . In the pre-disassembly pretreatment method for meat carcass that is subjected to thermal heat treatment heated by warm water , the thermal heat treatment tank is covered with a steam recovery duct after the thermal heat treatment is performed, so that the inside of the thermal heat treatment tank is made into a substantially closed space. The steam is supplied into the thermal heat treatment tank, the interior of the thermal heat treatment tank is cleaned with the steam, and the cleaned steam is collected in a steam recovery pipe through the steam recovery duct.

また、前記食肉屠体の解体前処理方法を実施する装置の発明として、食肉屠体に初期切断、放血を含む前処理を施す前処理手段を備え、前処理手段により前記食肉屠体に前記前処理を施した後、該食肉屠体に脱毛前の温熱処理を施すように構成された食肉屠体の解体前処理装置であって、前記食肉屠体を移動せしめる移動コンベアが内設されるとともに両端が開閉可能な中空の放血処理槽と、該放血処理槽の排出通路の下流側に設けられて該油脂分、血液分等の一次廃棄物を処理する一次廃棄物処理装置と、前記放血処理槽からの廃液を処理する廃液処理装置と、前記廃棄物排出通路に設けられて前記放血処理槽からの前記一次廃棄物排出時には前記放血処理槽の排出通路と一次廃棄物処理装置を接続し、前記放血処理槽からの前記廃液排出時には前記放血処理槽の排出通路と廃液処理装置とを接続する切換弁とを備えてなることを特徴とする食肉屠体の解体前処理装置を提案する。   In addition, as an invention of an apparatus for performing the method for pre-disassembling a meat carcass, the meat carcass includes pre-processing means for performing pre-processing including initial cutting and blood release, and the pre-processing means applies the pre-processing means to the meat carcass. A processing apparatus for disassembling a meat carcass configured to perform a heat treatment before hair removal on the meat carcass after the processing, and a moving conveyor for moving the meat carcass is provided in the apparatus. A hollow blood release treatment tank that can be opened and closed at both ends, a primary waste treatment apparatus that is provided downstream of the discharge passage of the blood release treatment tank and that treats primary waste such as fats and oils and blood, and the blood release treatment A waste liquid treatment apparatus for treating a waste liquid from a tank, and a discharge path of the blood discharge treatment tank and a primary waste treatment apparatus are connected to the waste discharge treatment path when the primary waste is discharged from the blood discharge treatment tank, Discharge of the waste liquid from the blood discharge treatment tank Proposes dismantling pretreatment apparatus meat carcasses, characterized by comprising a switching valve for connecting the discharge passage and the waste liquid treatment apparatus of the exsanguination process tank.

かかる発明によれば、食肉屠体に閉鎖空間での温熱処理を施す前工程で、一部または全部が外部に開放された開放空間、具体的には食肉屠体を移動せしめる移動コンベアが内設されるとともに両端が開閉可能な中空の放血処理槽内で食肉屠体に初期切断、放血を含む前処理を施すので、食肉屠体の血液や外皮の破片は前記放血処理槽の内壁に当たった後、該放血処理槽の下部に落下して溜められてから該放血処理槽外に導出されるので、前記処理室内に食肉屠体の血液や外皮の破片が飛散して該処理室内を汚染するのを回避できるとともに、衛生面でも良好な状態を保持できる。   According to this invention, in the pre-process in which the heat treatment in the closed space is performed on the meat carcass, an open space in which part or all of the meat carcass is opened to the outside, specifically, a moving conveyor for moving the meat carcass is provided. At the same time, the meat carcass is initially cut and subjected to pretreatment including exsanguination in a hollow exsanguination chamber that can be opened and closed at both ends, so that the blood of the meat carcass and debris of the outer skin hit the inner wall of the exsanguination chamber Then, after being dropped and stored in the lower part of the blood-bleeding treatment tank, it is led out of the blood-bleeding treatment tank, so that blood of the meat carcass and debris of the outer skin are scattered in the treatment room to contaminate the treatment room. Can be avoided, and a good state of hygiene can be maintained.

また、前記放血処理槽内での初期切断、放血を含む前処理後に、該放血処理槽の廃棄物排出通路に設置された切換弁（切換え手段）によって放血処理槽と一次廃棄物処理装置とを接続し、放血処理槽内を閉鎖状態にして該放血処理槽内に蒸気を噴出し、該蒸気により放血処理槽の内部を洗浄し、かかる蒸気洗浄工程による油脂分、血液分等の一次廃棄物を前記切換弁を通して前記一次廃棄物処理装置に排出し、該一次廃棄物を肥料等に活用する。
また、前記蒸気洗浄工程終了後に、前記切換弁を切り換えて前記放血処理槽と前記一次廃棄物処理装置に対して独立して配置された廃液処理装置とを接続し、放血処理槽内を閉鎖状態にして該放血処理槽内に水を噴出して該水により放血処理槽の内部を洗浄して前記蒸気洗浄工程における残存付着物を洗い流し、この廃液を前記廃液処理装置に排出する。 In addition, after the initial cutting and pretreatment including the exsanguination in the exsanguination treatment tank, the exsanguination treatment tank and the primary waste disposal apparatus are connected by a switching valve (switching means) installed in the waste discharge passage of the exsanguination treatment tank. Connected, the blood release treatment tank is closed, and steam is spouted into the blood discharge treatment tank, the inside of the blood release treatment tank is washed with the vapor, and primary waste such as oil and fat and blood in the vapor washing process Is discharged to the primary waste treatment apparatus through the switching valve, and the primary waste is used as fertilizer or the like.
Further, after completion of the steam cleaning step, the switching valve is switched to connect the blood discharge treatment tank and the waste liquid treatment apparatus disposed independently of the primary waste treatment apparatus, and the blood discharge treatment tank is closed. Then, water is spouted into the blood discharge treatment tank, the inside of the blood discharge treatment tank is washed with the water, the remaining deposits in the steam washing step are washed away, and the waste liquid is discharged to the waste liquid treatment apparatus.

従って、かかる発明によれば、閉鎖状態にした放血処理槽内に蒸気を噴出して該放血処理槽内の油脂分、血液分等の一次廃棄物を一次廃棄物処理装置に完全に排出してから、蒸気による洗浄とは分離して、該放血処理槽内に水を噴出して該水によって蒸気洗浄工程における残存付着物を洗い流すので、従来技術のような蒸気洗浄と水洗浄とを重複して行う工程に比べて放血処理槽内の汚染物質の除去効果が大きくなり、放血処理槽内の洗浄時間を短縮できるとともに、洗浄用の蒸気及び水の消費量を低減できる。   Therefore, according to this invention, steam is spouted into the closed blood release treatment tank, and primary wastes such as fats and oils and blood in the blood release treatment tank are completely discharged to the primary waste treatment apparatus. Therefore, it separates from the cleaning with steam, and jets water into the blood discharge treatment tank to wash away the remaining deposits in the steam cleaning process with the water. In comparison with the steps performed in this step, the effect of removing contaminants in the blood release treatment tank is increased, the cleaning time in the blood release treatment tank can be shortened, and the consumption of cleaning steam and water can be reduced.

また、廃液処理負荷の大きい油脂分、血液分等の一次廃棄物の蒸気による洗浄処理を水洗浄の前に水を混入することなく施して、かかる蒸気による洗浄処理液を水洗浄の洗浄処理液とは別個に一次廃棄物処理装置に排出し、次いで放血処理槽内の水洗浄を行うので、蒸気洗浄と水洗浄とを重複して行う工程に比べて放血処理槽内洗浄時の廃液処理負荷を低減できて、放血処理槽内の洗浄作業効率を向上できる。
さらに、前記油脂分、血液分等の一次廃棄物の蒸気による洗浄処理時に水が混入しないので、蒸気による洗浄処理液からの油脂分、血液分等の活用成分の抽出を容易化できる。 In addition, cleaning with steam of primary waste such as fats and oils and blood with a large waste liquid processing load is performed without mixing water before water cleaning. Waste water treatment load at the time of washing in the blood discharge treatment tank compared to the process of performing steam washing and water washing redundantly Can be reduced, and the cleaning work efficiency in the blood discharge treatment tank can be improved.
Further, since water is not mixed during the cleaning process using the steam of the primary waste such as the fats and oils and blood, it is possible to facilitate the extraction of the utilization components such as the fats and oils and the blood from the cleaning process liquid using the steam.

かかる発明において、好ましくは、前記放血処理槽は、内部通路断面の幅が下部になるに従い縮小するように形成されるとともに、前記排出通路側が下方に位置するように傾斜して設置されてなる。
このように構成すれば、放血処理槽の下部の縮小部に洗浄処理液が溜まり易く、かつ放血処理槽を排出通路側が下方になるように傾斜しているので洗浄処理液を一箇所に集中して排出でき、洗浄処理液の排出を円滑に行うことができる。 In this invention, preferably, the blood discharge treatment tank is formed so as to be reduced as the width of the cross section of the internal passage becomes lower, and is installed so as to be inclined so that the discharge passage side is located below.
If comprised in this way, since a washing | cleaning process liquid is easy to accumulate in the reduction | decrease part of the lower part of a blood-bleeding processing tank, and the blood-bleeding processing tank is inclined so that the discharge channel side may become downward, a washing | cleaning process liquid is concentrated on one place. The cleaning treatment liquid can be discharged smoothly.

さらに、前記油脂分、血液分等の一次廃棄物の蒸気による洗浄処理時に水が混入しないので、蒸気による洗浄処理液からの油脂分、血液分等の活用成分の抽出を容易化できる。 In addition, cleaning with steam of primary waste such as fats and oils and blood with a large waste liquid processing load is performed without mixing water before water cleaning. Since it is discharged to the primary waste treatment apparatus 11 separately, and then the water washing in the blood discharge treatment tank is performed, compared with the process in which steam washing and water washing are performed in duplicate, the blood treatment inside the blood discharge treatment tank 1 is washed 50 times. The waste liquid treatment load can be reduced, and the cleaning work efficiency in the blood discharge treatment tank 1 can be improved.
Further, since water is not mixed during the cleaning process using the steam of the primary waste such as the fats and oils and blood, it is possible to facilitate the extraction of the utilization components such as the fats and oils and the blood from the cleaning process liquid using the steam.
