Description
本発明は、食肉処理施設において、食肉処理施設の衛生管理基準を満たしながら、牛、豚等、家畜の屠畜・解体及び内臓処理等の食肉処理過程に冷熱及び給湯を供給するとともに、冷温熱使用量を平準化して省エネを可能にした冷温熱供給方法及び装置に関する。 In the meat processing facility, while satisfying the hygiene management standards of the meat processing facility, while supplying cooling and hot water to the meat processing process such as cattle, pigs, slaughtering and dismantling of livestock and internal organs processing, The present invention relates to a cooling / heating supply method and apparatus that can save energy by leveling the amount used.
従来、食肉処理施設には、牛、豚等の屠畜及び解体を行なう屠畜解体室、及び内臓処理を行う内臓処理室と、後工程の、懸肉処理（枝肉洗浄後の水切り）、枝肉冷却、計量、格付け、下見、セリ、保管、出荷等を行なう懸肉室、及びさらに部分肉カット等を行なう処理室等が設けられている。これらの処理室での食肉処理過程において、法律で定められた衛生管理基準を遵守するために、大量の温水、冷水、氷等が使用されている。そのため、食肉処理施設では、電気、ガス等、大量のエネルギーが消費されている。 Conventionally, in a meat processing facility, a slaughtering and demolition room for slaughtering and dismantling of cattle and pigs, an internal organs processing room for performing internal organ processing, and a carcass processing (draining after carcass washing), carcass There are a suspension chamber for cooling, weighing, rating, previewing, seri, storage, shipping, etc., and a processing chamber for performing partial meat cutting and the like. In the meat processing process in these processing rooms, a large amount of hot water, cold water, ice, etc. are used in order to comply with the sanitary management standards defined by law. Therefore, a large amount of energy such as electricity and gas is consumed in the meat processing facility.
屠畜及び解体の食肉処理過程となる皮剥ぎライン及び背割りラインには、皮剥ぎ機、背割りソー及びナイフ等の食肉処理器具の洗浄殺菌用に８３℃以上の熱湯が要求されている。そのため、食肉処理過程で充分な給湯量を確保するため、ボイラーが常時運転されている。内臓処理を行う内臓処理室には、内臓を煮沸した後の冷却のために、５℃の冷水が要求される。そのため、内臓処理室では、従来から氷水が使用されている。 Hot water at 83 ° C. or higher is required for the skinning line and the back split line, which are meat processing processes for slaughter and dismantling, for cleaning and sterilizing meat processing equipment such as a skin peeling machine, a back split saw and a knife. Therefore, the boiler is always operated in order to ensure a sufficient amount of hot water supply in the meat processing process. In the visceral treatment chamber for performing the visceral treatment, cold water of 5 ° C. is required for cooling after boiling the viscera. Therefore, ice water has been conventionally used in the visceral treatment chamber.
屠畜、解体を行う屠畜解体室及び後工程となる懸肉室の室温は、１０℃に維持されるが、豚の体温は４０℃以上あり、時には４０℃近くまで上昇している屠体も持ち込まれるため、負荷変動が大きい。そのため、かかる負荷変動にも対応できる冷熱供給が必要とされている。 The room temperature of the slaughterhouse and slaughterhouse for performing slaughter and dismantling and the suspension room as a post-process is maintained at 10 ° C, but the body temperature of the pig is 40 ° C or higher, and sometimes the carcass has risen to nearly 40 ° C. The load fluctuation is large. Therefore, there is a need for cold supply that can cope with such load fluctuations.
食肉用家畜を屠畜し加工処理する食肉処理場の冷却作湯システムとして、特許文献１には、ＣＯ２を熱媒体としたヒートポンプ装置を使用することが開示されている。ＣＯ２を熱媒体としたヒートポンプ装置は、圧縮工程でＣＯ２を超臨界状態にすることにより、約９０℃の高温水を製造でき、給湯用として好適であることが知られている。 As a cooling hot water system for a slaughterhouse for slaughtering and processing meat livestock, Patent Document 1 discloses the use of a heat pump device using CO 2 as a heat medium. It is known that a heat pump apparatus using CO 2 as a heat medium can produce high-temperature water of about 90 ° C. by bringing CO 2 into a supercritical state in a compression process, and is suitable for hot water supply.
特許文献１に開示されたシステムでは、空気を熱源としＣＯ２を熱媒体としたヒートポンプ装置を屠畜解体室内又は室外近傍に設置している。そして、屠畜解体時に食肉用屠体から放散される熱を主たる熱源として該ヒートポンプ装置で高温水を製造するとともに、同時に屠畜解体室等、処理室内雰囲気の冷却消霧を行っている。このシステムは、既設の屠畜解体室等の処理室の大幅な改造を伴うため、省エネルギー対策として既設の食肉処理施設に適用することは困難である。 In the system disclosed in Patent Document 1, a heat pump device using air as a heat source and CO 2 as a heat medium is installed in the slaughterhouse or in the vicinity of the outdoor. And while producing high temperature water with this heat pump device by using the heat dissipated from the meat carcass at the time of slaughtering as a main heat source, cooling and fogging of the atmosphere in the processing room such as the slaughtering room is performed at the same time. Since this system is accompanied by a large remodeling of a processing room such as an existing slaughterhouse demolition room, it is difficult to apply this system to an existing meat processing facility as an energy saving measure.
特許文献２には、氷蓄熱槽を備えた冷凍装置の凝縮熱をＣＯ２給湯用ヒートポンプの熱源として利用して、季節や寒冷地等に関係なく年間を通して９０℃前後の高温水を安定して供給可能とすることが開示されている。 Patent Document 2, the heat of condensation of the refrigeration system including an ice thermal storage tank used as the heat source of the CO 2 hot water supply pump, stable and 90 ° C. before and after the hot water throughout the year irrespective of the season or a cold region, etc. It is disclosed that supply is possible.
さらに、特許文献３には、氷蓄熱ユニット及び給湯ユニットを備えた空気調和装置において、製氷用蓄熱運転及び給湯蓄熱運転を同時に行なう同時運転から、いずれか一方の運転に切り替え可能とする制御手段が開示されている。 Furthermore, in Patent Document 3, in an air conditioner including an ice heat storage unit and a hot water supply unit, there is a control means that can switch from simultaneous operation in which ice storage heat storage operation and hot water storage heat operation are performed simultaneously to either one of the operations. It is disclosed.
食肉処理施設においては、前述のように、大量のエネルギーが消費されるため、エネルギー使用量の節減を目的として、太陽光発電による自然エネルギーの導入、夜間電力を使用する氷蓄熱によるエネルギー負荷の平準化と言ったエネルギー対策が図られてきた。しかし、法律に適った食肉処理施設の衛生管理基準を維持しながら、食肉処理工程全体を見据えてシステム的な省エネ対策を行なうような手段は、従来講じられていなかった。 As mentioned above, a large amount of energy is consumed at slaughterhouses. For the purpose of reducing energy consumption, the introduction of natural energy through solar power generation and the leveling of energy load due to ice heat storage using nighttime electricity are used. Energy countermeasures such as conversion have been attempted. However, there has been no conventional means for systematic energy saving measures with a view to the entire slaughtering process while maintaining sanitary management standards for slaughtering facilities that comply with the law.
本発明は、かかる従来技術の課題に鑑み、食肉処理施設における屠畜解体及び内臓処理等の食肉処理過程において必要となる冷熱及び給湯負荷に対応して、エネルギー負荷の平準化を達成し、法律に適った食肉処理施設の衛生管理基準を維持できる省エネルギーシステムを構築することを目的とする。 In view of the problems of the prior art, the present invention achieves energy load leveling in response to cold and hot water loads required in the meat processing process such as slaughtering and internal organ processing in the meat processing facility, The purpose is to build an energy-saving system that can maintain sanitary management standards for slaughterhouses that are suitable for food.
かかる目的を達成するため、本発明の食肉処理施設の冷温熱供給装置は、
ＣＯ２を冷媒としたヒートポンプ装置と該ヒートポンプ装置で冷却されたブラインを冷熱源とする氷蓄熱装置とを備え、食肉処理施設の屠畜解体室、懸肉室及び内臓処理室に屠体解体処理用又は空調用の冷温熱を供給する食肉処理施設の冷温熱供給装置において、
前記ヒートポンプ装置で製造された高温水を貯留する貯湯槽、及び該貯湯槽に貯留された高温水を前記屠畜解体室に温熱源として供給する送湯装置と、
前記氷蓄熱装置で製造された冷水を前記内臓処理室に冷熱源として供する冷熱源供給装置と、
前記ヒートポンプ装置と氷蓄熱装置間にブラインを循環させる第１ブライン循環路と、
該第１ブライン循環路から分岐され、該ヒートポンプ装置又は氷蓄熱装置で冷却されたブラインを前記屠畜解体室及び懸肉室の空調器に送る第２ブライン循環路と、
該第１ブライン循環路と第２ブライン循環路との分岐部に設けられた切換弁と、を備えたものである。
In order to achieve such an object, the cold / heat supply apparatus for meat processing facilities of the present invention comprises:
A heat pump device using CO 2 as a refrigerant and an ice heat storage device using brine cooled by the heat pump device as a cold heat source, and carcass dismantling processing in the slaughterhouse, suspension room and internal organs processing room of the meat processing facility In the cool / heat supply device of the meat processing facility that supplies the cool / heat for air conditioning or air conditioning,
A hot water storage tank for storing hot water produced by the heat pump device, and a hot water supply apparatus for supplying the hot water stored in the hot water storage tank as a heat source to the slaughterhouse,
A cold heat source supply device for supplying cold water produced by the ice heat storage device to the internal treatment chamber as a cold heat source;
A first brine circulation path for circulating brine between the heat pump device and the ice heat storage device;
A second brine circuit branching from the first brine circuit and sending the brine cooled by the heat pump device or the ice heat storage device to the air conditioner of the slaughterhouse and suspension chamber;
And a switching valve provided at a branch portion between the first brine circulation path and the second brine circulation path.
本発明装置では、食肉処理を行なわない時に、ＣＯ２を冷媒とするヒートポンプ装置を稼動させて、屠畜解体室で必要とする８３℃以上の高温水を貯湯槽に貯留する。食肉処理施設の皮剥ぎライン及び背割りラインにおける衛生管理基準を維持できる。この蓄熱と並行して、第１ブライン循環路を通して、ヒートポンプ装置で冷却されたブラインを氷蓄熱装置に送ることにより、氷蓄熱装置の蓄氷を行なう。 In the apparatus of the present invention, when the meat processing is not performed, a heat pump device using CO 2 as a refrigerant is operated, and high-temperature water of 83 ° C. or higher required in the slaughterhouse demolition room is stored in the hot water storage tank. Sanitary control standards can be maintained in the slaughtering and skinning lines. In parallel with this heat storage, the ice cooled by the ice heat storage device is performed by sending the brine cooled by the heat pump device to the ice heat storage device through the first brine circulation path.
食肉処理時には、前記切換弁でブラインの流路を切り換えることで、第２ブライン循環路を通して、ヒートポンプ装置又は氷蓄熱装置で冷却されたブラインを屠畜解体室及び懸肉室の空調器に送り、屠畜解体室及び懸肉室の空調を行なうことができる。同時に、氷蓄熱装置で製造された氷水を冷熱源として内臓処理室で煮沸された内臓、その他の冷却を行なう。
このように、食肉処理を行なわない時間帯に蓄熱蓄氷運転を行なうので、食肉処理時にヒートポンプ装置を稼動させる必要がなくなる。そのため、1日のエネルギー負荷を平準化でき、１日の電力等のエネルギー消費量を平準化できる。
At the time of meat processing, by switching the brine flow path with the switching valve, the brine cooled by the heat pump device or the ice heat storage device is sent to the air conditioner of the slaughterhouse and suspension room through the second brine circulation path, Air conditioning of the slaughter room and the suspension room can be performed. At the same time, the internal organs boiled in the internal organ processing chamber are cooled by using ice water produced by the ice heat storage device as a cold heat source.
Thus, since the heat storage ice storage operation is performed during a time period when the meat processing is not performed, it is not necessary to operate the heat pump device during the meat processing. Therefore, the daily energy load can be leveled, and the daily energy consumption such as electric power can be leveled.
また、氷蓄熱装置で製造した氷水を冷熱源として内臓処理室における冷却を行なうと共に、該氷水で冷却した冷ブラインを用いて、屠畜解体室及び懸肉室の空調を行なうことができる。これによって、内臓処理室、屠畜解体室及び懸肉室に必要な冷熱源を氷蓄熱装置の氷水の冷熱源のみを使用してまかなうことができるので、省エネを可能にする。
また、内臓処理室では、従来のように大量の氷水を製造する必要がなくなるので、設備費の削減及び節水が可能になる。
Moreover, while cooling the internal organs processing chamber using ice water produced by the ice heat storage device as a cold heat source, air conditioning of the slaughterhouse and the suspension chamber can be performed using the cold brine cooled by the ice water. As a result, the cooling source required for the visceral processing chamber, the slaughterhouse and the suspension chamber can be provided using only the cooling source of the ice water of the ice heat storage device, thus enabling energy saving.
In addition, in the visceral treatment chamber, it is not necessary to produce a large amount of ice water as in the prior art, so that the equipment cost can be reduced and water can be saved.
また、前記切換弁により、第１ブライン循環路と第２ブライン循環路とを切り換え可能にしたので、氷蓄熱装置での蓄氷と、屠畜解体室及び懸肉室の空調とを、同時に、又は夫々別個に行なうことができる。これによって、冷温熱供給装置の運転の自由度を広げることができる。なお、氷蓄熱装置の氷残量を常に監視し、余剰分があればブラインを第１ブライン循環路を通すことによって、氷水の冷熱源を有効に取り出すことができる。 In addition, since the first brine circulation path and the second brine circulation path can be switched by the switching valve, the ice storage in the ice heat storage device and the air conditioning of the slaughterhouse dismantling room and the suspension room are performed simultaneously. Or each can be done separately. Thereby, the freedom degree of operation | movement of a cold / hot heat supply apparatus can be expanded. In addition, the ice heat storage device is always monitored, and if there is a surplus, the cold water source of ice water can be effectively taken out by passing the brine through the first brine circulation path.
本発明装置において、太陽熱集熱装置と、該太陽熱集熱器で製造した高温水を貯留する第２貯湯槽と、該第２貯湯槽に貯留された高温水を食肉処理施設に温熱源として供給する第２送湯装置と、を備えているとよい。このように、太陽熱集熱装置を付設することによって、温熱源の補充が可能になる。なお、太陽熱集熱装置で製造された高温水は、比較的低温であるので、ヒートポンプ装置で製造された高温水と混合することで温度調節用として使用できる。あるいは太陽熱集熱装置で製造された高温水を、単独で作業員の手洗い用等として使用できる。 In the apparatus of the present invention, a solar heat collector, a second hot water tank storing hot water produced by the solar heat collector, and supplying the hot water stored in the second hot water tank to the meat processing facility as a heat source And a second hot water supply device. In this manner, the solar heat collecting device is attached, so that the heat source can be supplemented. In addition, since the high temperature water manufactured with the solar heat collecting device is comparatively low temperature, it can be used for temperature control by mixing with the high temperature water manufactured with the heat pump device. Alternatively, high-temperature water produced by a solar heat collector can be used alone for hand washing of workers.
また、本発明装置において、前記冷熱源供給装置が、氷蓄熱装置の氷水と被冷却水とを熱交換して被冷却水を冷却する熱交換器と、水補給部を備え該熱交換器と内臓処理室との間に被冷却水を循環させる被冷却水循環路と、を備えているとよい。これによって、該被冷却水の循環量を調整することによって、内臓処理室に供給する被冷却水の温度を調整できると共に、内臓処理室で消費される被冷却水量に応じて水補給部での給水量を調整できるので、被冷却水の無駄な使用をなくし、節水が可能になる。また、補充水量を調整することにより、被冷却水の温度管理を正確に行なうことができるので、内臓処理の衛生管理基準が遵守され、内臓の品質維持が可能となる。 Further, in the apparatus of the present invention, the cold heat source supply device includes a heat exchanger that cools the water to be cooled by exchanging heat between the ice water and the water to be cooled of the ice heat storage device, and a water replenishment unit. A cooling water circulation path for circulating the cooling water between the built-in treatment chamber and the built-in treatment chamber may be provided. Thus, by adjusting the circulation amount of the cooling water, the temperature of the cooling water supplied to the visceral treatment chamber can be adjusted, and the water replenishing unit can adjust the temperature of the cooling water consumed in the visceral treatment chamber. Since the amount of water supply can be adjusted, wasteful use of the water to be cooled is eliminated and water can be saved. Moreover, since the temperature control of the to-be-cooled water can be accurately performed by adjusting the amount of replenishing water, the hygiene management standards for the internal organ treatment are observed, and the internal organ quality can be maintained.
次に、前記本発明装置を用いた本発明の食肉処理施設の冷温熱供給方法は、
ヒートポンプ装置のガスクーラで高温水を製造し、該高温水を貯湯槽に貯留すると共に、該ヒートポンプ装置の蒸発器で冷却したブラインを前記氷蓄熱装置に供して氷水を製造する蓄熱蓄氷ステップと、
該貯湯槽に貯留された高温水を、屠畜解体室に食肉処理器具の洗浄殺菌用として供する給湯ステップと、
氷蓄熱装置で製造した氷水と熱交換させて冷却したブラインを屠畜解体室及び懸肉室の空調器に送って該屠畜解体室及び懸肉室の空調を行なう空調ステップと、
氷蓄熱装置の氷水を冷熱源として該内臓処理室の冷却を行なう冷却ステップと、からなり、
食肉処理を行なわない時に前記蓄熱蓄氷ステップを行い、食肉処理を行なう時に、前記給湯ステップ、空調ステップ及び冷却ステップを行なうようにしたものである。
Next, the method for supplying cold and hot heat of the meat processing facility of the present invention using the apparatus of the present invention,
A heat storage ice storage step of producing high-temperature water with a gas cooler of a heat pump device, storing the high-temperature water in a hot water storage tank, and supplying ice water to the ice heat storage device using brine cooled by an evaporator of the heat pump device;
A hot water supply step for supplying high-temperature water stored in the hot water storage tank to the slaughterhouse demolition room for washing and sterilizing meat processing instruments;
An air conditioning step of air-conditioning the slaughterhouse and suspension room by sending brine cooled with ice water produced by the ice heat storage device to the air conditioner of the slaughterhouse and suspension room;
A cooling step for cooling the visceral treatment chamber using ice water of the ice heat storage device as a cold heat source,
The heat storage ice storage step is performed when meat processing is not performed, and the hot water supply step, air conditioning step, and cooling step are performed when meat processing is performed.
本発明方法では、食肉処理を行なわない時に前記蓄熱蓄氷ステップを行い、食肉処理を行なう時に、前記給湯ステップ、空調ステップ及び冷却ステップを行なうようにしたので、食肉処理時にヒートポンプ装置及び氷蓄熱装置を稼動させる必要がなくなり、１日のエネルギー負荷を平準化でき、１日の電力等のエネルギー消費量の平準化を達成できる。 In the method of the present invention, the heat storage ice storage step is performed when the meat processing is not performed, and the hot water supply step, the air conditioning step and the cooling step are performed when the meat processing is performed, so that the heat pump device and the ice heat storage device are processed during the meat processing. It is no longer necessary to operate the vehicle, and the daily energy load can be leveled, and the level of energy consumption such as daily power can be leveled.
また、前記空調ステップ及び冷却ステップは、氷蓄熱装置の氷水の冷熱源のみで行なうことができる。従って、食肉処理施設の消費電力を節減して、省エネを可能にする。特に、内臓処理室では、従来のように、煮沸処理された内臓、その他の冷却のために大量の氷水を製造する必要がなくなる。そのため、設備費の削減及び節水が可能になる。
また、給湯ステップでは、屠畜解体室に食肉処理器具の洗浄殺菌に必要な８３℃の熱湯を供給でき、これによって、食肉処理施設の皮剥ぎライン及び背割りラインにおける衛生管理基準を維持できる。
Further, the air conditioning step and the cooling step can be performed only by the ice water cooling heat source of the ice heat storage device. Therefore, the power consumption of the meat processing facility is reduced and energy saving is enabled. In particular, in a visceral treatment chamber, it is not necessary to produce a large amount of ice water for cooling the boiled viscera or other organs as in the prior art. As a result, facility costs can be reduced and water can be saved.
Further, in the hot water supply step, hot water of 83 ° C. necessary for cleaning and sterilizing the meat processing equipment can be supplied to the slaughterhouse dismantling room, thereby maintaining the sanitary management standards in the skinning line and the back split line of the meat processing facility.
本発明方法において、食肉処理が行なわれない夜間に蓄熱蓄氷ステップを行なうと共に、食肉処理が行なわれる昼間に給湯ステップ、空調ステップ及び冷却ステップを行なうようにするとよい。このように、電力等のエネルギー消費が少ない夜間に、蓄熱蓄氷ステップを行ない、食肉処理を行なう昼間にヒートポンプ装置を休止させることにより、１日を通して、エネルギー負荷を平準化できる。 In the method of the present invention, it is preferable that the heat storage ice storage step is performed at night when the meat processing is not performed, and the hot water supply step, the air conditioning step and the cooling step are performed during the day when the meat processing is performed. Thus, the energy load can be leveled throughout the day by performing a heat storage ice storage step at night when energy consumption such as electric power is low and suspending the heat pump device during the day when meat processing is performed.
本発明方法において、食肉処理時に貯湯槽の高温水が不足するか又は氷蓄熱装置の蓄氷が不足したとき、ヒートポンプ装置を稼動させ、該貯湯槽に高温水を供給すると共に、該ヒートポンプ装置で冷却したブラインを、屠畜解体室及び懸肉室の空調器に送って該屠畜解体室及び懸肉室の空調を行なうようにするとよい。
このような追いかけ運転を行なうことにより、食肉処理中に高温水又は蓄氷が不足した場合でも食肉処理を続行できる。また、各処理室の負荷変動に対しても、ヒートポンプ装置の追いかけ運転を行なうことで、高負荷時にも十分対応することができる。
In the method of the present invention, when the hot water in the hot water storage tank is insufficient at the time of meat processing or the ice storage in the ice heat storage device is insufficient, the heat pump device is operated to supply the hot water to the hot water storage tank, and the heat pump device It is good to send the cooled brine to the air conditioner of a slaughterhouse and a suspension room, and to air-condition this slaughterhouse and a suspension room.
By performing such a chasing operation, the meat processing can be continued even when high-temperature water or ice storage is insufficient during the meat processing. In addition, it is possible to sufficiently cope with load fluctuations in each processing chamber even when the load is high by performing the chasing operation of the heat pump device.

Thus, energy load leveling can be achieved, and in the hot water supply step, high-temperature water of 83 ° C. or higher can be supplied to the slaughterhouse and suspension room, and the sanitary management standard can be satisfied.
また、氷蓄熱装置の冷熱源のみで屠畜解体室及び懸肉室の空調と、内臓処理室への冷熱源供給を同時に行なうことができるので、省エネを可能とする。 In addition, the air conditioning of the slaughterhouse and the suspension room and the supply of the cold heat source to the visceral treatment chamber can be performed simultaneously with only the cold heat source of the ice heat storage device, thereby enabling energy saving.

(When supplying cold heat directly from the CO 2 water heater 12)
During the meat processing, when the ice storage in the ice heat storage tank 14 or the amount of hot water stored in the hot water storage tank 16 is insufficient, an operation mode (hereinafter referred to as “chase operation”) when supplying cold heat directly from the CO 2 water heater 12. ) Is shown in FIG.

本実施形態によれば、食肉処理を行わない夜間に、貯湯槽１６への貯湯と、氷蓄熱槽１４の蓄氷とを行い、通常、食肉処理を行なう昼間にＣＯ２給湯機１２を稼動させないので、１日を通してエネルギー負荷を平準化できる。
また、ＣＯ２給湯機１２を用いて、屠畜解体室１１０に８３℃以上の高温水を供給できるので、衛生管理基準を満たすことができる。
According to the present embodiment, hot water storage in the hot water storage tank 16 and ice storage in the ice heat storage tank 14 are performed at night when no meat processing is performed, and the CO 2 water heater 12 is not normally operated during the day when meat processing is performed. Therefore, the energy load can be leveled throughout the day.
Further, by using a CO 2 water heater 12, can be supplied with 83 ° C. or more hot water to butchery畜解member chamber 110 can be filled hygiene standards.
また、食肉処理運転時には、ＣＯ２給湯機１２を稼動させず、貯湯槽１６に貯留された高温水を温熱源とすると共に、氷蓄熱槽１４の蓄氷を冷熱源とし、この冷熱源のみを用いて、屠畜解体室１１０及び懸肉室１３０の空調と、内臓処理室１２０への被冷却水の供給を行なうことができるので、省エネを達成できる。 Further, during the meat processing operation, the CO 2 water heater 12 is not operated, the hot water stored in the hot water tank 16 is used as a heat source, the ice storage in the ice heat storage tank 14 is used as a cold heat source, and only this cold heat source is used. By using it, air conditioning of the slaughterhouse dismantling chamber 110 and the suspension chamber 130 and the supply of cooling water to the internal organ processing chamber 120 can be performed, so that energy saving can be achieved.

As a result, the meat processing operation is not hindered. Moreover, the high temperature water stored in the hot water tank 20 can be used for other uses of the meat processing facility 10.
また、内臓処理室１２０への冷熱源供給手段として、従来は、大量の氷水を製造していたが、本実施形態では、氷蓄熱槽１４の冷水で冷却された被冷却水を被冷却水循環路５２を介して内臓処理室１２０に循環供給している。そして、内臓処理室１２０での冷水使用量に合わせて、被冷却水循環路５２に常温水を補充するようにしているので、被冷却水の無駄な使用を無くすことができる。また、補充水量を調整することにより、被冷却水の温度管理を正確に行なうことができるので、内臓処理の衛生管理基準が遵守され、内臓の品質維持が可能となる。 Further, as a cooling heat source supply means to the internal processing chamber 120, conventionally, a large amount of ice water has been manufactured. In the present embodiment, the cooling water cooled by the cold water in the ice heat storage tank 14 is used as the cooling water circulation path. It is circulated and supplied to the visceral processing chamber 120 via 52. And since the normal temperature water is replenished to the to-be-cooled water circulation path 52 according to the amount of cold water used in the internal organs processing chamber 120, useless use of the to-be-cooled water can be eliminated. Moreover, since the temperature control of the to-be-cooled water can be accurately performed by adjusting the amount of replenishing water, the hygiene management standards for the internal organ treatment are observed, and the internal organ quality can be maintained.
また、本実施形態では、食肉処理運転中に、貯湯槽１６の貯湯量又は氷蓄熱槽１４の蓄氷量が不足した場合、前記追いかけ運転を行なって、貯湯量又は蓄氷量を補充できるので、食肉処理運転に支障をきたすおそれがなくなる。
さらに、屠畜解体室１１０及び懸肉室１３０の負荷変動が激しい場合でも、ヒートポンプ装置の追いかけ運転を行なうことで、十分対応することができる。
Moreover, in this embodiment, when the amount of hot water stored in the hot water storage tank 16 or the amount of ice stored in the ice heat storage tank 14 is insufficient during the meat processing operation, the chasing operation can be performed to replenish the amount of hot water stored or ice stored. There is no risk of disturbing the meat processing operation.
Furthermore, even when the load fluctuations in the slaughterhouse dismantling chamber 110 and the suspension chamber 130 are severe, it is possible to sufficiently cope with the chasing operation of the heat pump device.
