FIG. 5 is a view for explaining the liquid circulation standby and the cleaning or sterilization of the liquid passage in the liquid processing apparatus for producing a carbon dioxide-containing beverage shown in FIG.

図4において、従来の炭酸ガス入り飲料製造用液体の液処理装置(以下、単に液処理装置と称することがある)5は、図示しない上流側の供給元から矢印F1の向きで送液配管POにより弁V1を経て送液部(図示では受タンク)Tへ供給された液体Lを、送液配管PAの途中に設けられたポンプPにより送液して高温(1例として135℃)で加熱殺菌処理する加熱機器Hと、該加熱機器Hと送液配管PBで接続されて前記高温の液体Lを常温(1例として30℃)へ冷却処理する冷却機器CAと、該冷却機器CAと送液配管PCで接続されて前記常温の液体Lを炭酸ガス吸収に適した常温以下の低温度(1例として1℃)まで冷却処理する冷却機器CBと、該冷却機器CBと送液配管PDで接続されて前記低温度の液体Lに炭酸ガスを所定濃度まで吸収させるカーボネータCCによって主に構成されている。   In FIG. 4, a conventional liquid processing apparatus (hereinafter sometimes simply referred to as a liquid processing apparatus) 5 for producing a beverage containing carbon dioxide gas is supplied from a non-illustrated upstream supply source in the direction of arrow F1. The liquid L supplied to the liquid feeding part (reception tank in the figure) T through the valve V1 is fed by a pump P provided in the middle of the liquid feeding pipe PA and heated at a high temperature (135 ° C. as an example). A heating device H for sterilization, a cooling device CA connected to the heating device H by a liquid feeding pipe PB and cooling the high temperature liquid L to room temperature (30 ° C. as an example), and the cooling device CA A cooling device CB that is connected by a liquid pipe PC and cools the liquid L at room temperature to a low temperature below normal temperature (1 ° C. as an example) suitable for carbon dioxide absorption, and the cooling device CB and a liquid supply pipe PD. Connect the carbon dioxide gas to the low temperature liquid L It is mainly constituted by a carbonator CC imbibing up to a concentration.

また、前記送液配管PDの途中には弁V6と弁V7によって構成される切換え弁VDが設けられ、弁V2を介して前記弁V7と前記送液部Tとを接続するリターン配管RPが設けられており、カーボネータCC内の液体Lは送液配管PPの途中に設けられたポンプP2によって図示しない充填装置に向けて送液されるようになっている。   Further, a switching valve VD composed of a valve V6 and a valve V7 is provided in the middle of the liquid supply pipe PD, and a return pipe RP for connecting the valve V7 and the liquid supply part T is provided via the valve V2. The liquid L in the carbonator CC is fed toward a filling device (not shown) by a pump P2 provided in the middle of the liquid feeding pipe PP.

次に、従来の液処理装置5の作用を図4および図5に基づいて説明する。
液処理装置5の製造運転時は、弁V1を開、弁V2を閉に、切換え弁VDの弁V6を開、弁V7を閉にして、図示しない上流側の供給元から送液部Tに送液された液体Lが、図4に太線で示すように、ポンプPによって送液部Tから矢印F2の方向に送液配管PA、加熱機器H、送液配管PB、冷却機器CA、送液配管PC、冷却機器CBへ、さらに、切換え弁VD経由で矢印F4の方向に送液配管PDをカーボネータCCに向けて送液され、前記カーボネータCCで炭酸ガスが所定量吸収されて滅菌済の炭酸ガス入り飲料となって、前記カーボネータCCからポンプP2によって送液配管PPを介して図示しない下流の充填装置へ送液される。
即ち、液体Lは、加熱機器Hでの高圧下の高温加熱により微生物が滅菌処理され、常温への冷却処理を経て、炭酸ガス吸収に適した常温以下の低温度まで冷却処理されて、カーボネータCCで所定濃度の炭酸ガスを吸収して炭酸ガス入り飲料となった後、下流側の充填装置でびん或いは缶等の容器に所定量充填される。
Next, the operation of the conventional liquid processing apparatus 5 will be described with reference to FIGS.
During the manufacturing operation of the liquid processing device 5, the valve V1 is opened, the valve V2 is closed, the valve V6 of the switching valve VD is opened, and the valve V7 is closed. As shown by a thick line in FIG. 4, the liquid L that has been fed is fed from the liquid feeding part T in the direction of the arrow F2 by the pump P to the liquid feeding pipe PA, the heating equipment H, the liquid feeding pipe PB, the cooling equipment CA, and the liquid feeding. The pipe PC and the cooling device CB are further fed via the switching valve VD in the direction of the arrow F4 toward the carbonator CC. The carbonator CC absorbs a predetermined amount of carbon dioxide and sterilized carbon dioxide. A beverage containing gas is supplied from the carbonator CC to a downstream filling device (not shown) via the liquid supply pipe PP by the pump P2.
That is, the liquid L is sterilized by microorganisms by high-temperature heating under high pressure in the heating device H, cooled to room temperature, cooled to a low temperature below room temperature suitable for carbon dioxide absorption, and then the carbonator CC After absorbing carbon dioxide of a predetermined concentration to obtain a drink containing carbon dioxide, a predetermined amount is filled in a container such as a bottle or a can with a downstream filling device.

ここで、前記充填装置等の下流側機器の運転が一旦停止となる事態が生じた場合には、前記液体Lは、弁V1を閉、弁V2を開として、また、切換え弁VDの弁V6を閉、弁V7を開として、図5に太線で示すように、ポンプPによって送液部Tから図示矢印F2の方向に送液配管PA,加熱機器H、送液配管PB、冷却機器CA、送液配管PC、冷却機器CB、送液配管PD、切換え弁VDへ、さらに、切換え弁VDから図示矢印FPの方向にリターン配管RPを経て送液部Tへのループで循環されて循環待機状態となり、切換え弁VDから下流側のカーボネータCCへの送液が停止される。   Here, when the operation of the downstream device such as the filling device is temporarily stopped, the liquid L closes the valve V1, opens the valve V2, and the valve V6 of the switching valve VD. Is closed, the valve V7 is opened, and as shown by a thick line in FIG. 5, the pump P feeds the liquid feeding pipe PA, the heating equipment H, the liquid feeding pipe PB, the cooling equipment CA in the direction of the arrow F2 from the liquid feeding section T.

また、液処理装置5は、製造運転の前或いは後は、加熱機器Hで加熱された熱水或いは過酢酸溶液等の適宜温度の滅菌液から成る洗浄または滅菌用液体S(図5では洗浄または滅菌用液体Sを( )表示している。)が、図5の太線で示すルートで所定時間循環されて、前記液体Lの通路が洗浄または滅菌される。   In addition, before or after the manufacturing operation, the liquid processing apparatus 5 is a cleaning or sterilizing liquid S (in FIG. 5, a cleaning or sterilizing liquid S or a sterilizing liquid having an appropriate temperature such as hot water or a peracetic acid solution). The sterilization liquid S is indicated by ()), and is circulated for a predetermined time in the route indicated by the thick line in FIG.

前記説明の従来の炭酸ガス入り飲料製造用液体の液処理装置5の技術では、切換え弁VDから送液部Tへ送液するリターン配管RPを経る液体Lが循環待機状態の場合に、一旦加熱機器Hにより高温の殺菌温度で加熱殺菌された液体Lが、冷却機器CAによって常温へ冷却され、さらに冷却機器CBによって常温以下の低温度まで冷却された後、再び送液部Tを経て加熱機器Hによって高温の殺菌温度まで再加熱を受けることになり、多くの熱エネルギーを消費し、エネルギーコストが多大となっている可能性がある。   In the technology of the conventional liquid processing apparatus 5 for producing beverage containing carbon dioxide gas as described above, when the liquid L passing through the return pipe RP fed from the switching valve VD to the liquid feeding part T is in a circulation standby state, it is heated once. The liquid L sterilized by heating at a high sterilization temperature by the device H is cooled to room temperature by the cooling device CA, and further cooled to a low temperature below the room temperature by the cooling device CB, and then again through the liquid feeding part T and the heating device. It will be reheated to high sterilization temperature by H, consumes a lot of heat energy, and energy cost may be great.

図1において、本発明の実施の形態に係わる炭酸ガス入り飲料製造用液体の液処理装置(以下、単に液処理装置と称することがある)1は、先に図4に基づいて説明した液処理装置5と同様に、送液部T、加熱機器H、冷却機器CA、冷却機器CB、カーボネータCCによって主に構成されているが、冷却機器CAと冷却機器CBが近い位置に配置されていて、冷却機器CAと冷却機器CBとを接続する送液配管PCの途中に弁V3、弁V4、弁V5によって構成される切換え弁VCが設けられ、弁V4と弁V2を介して送液部Tと接続するリターン配管RAが、また、弁V7と弁V5を接続するリターン配管RBが設けられている。
なお、前記リターン配管RAとリターン配管RBは、切換え弁VCの弁V5を開にすることにより接続状態とすることができるようになっている。
In FIG. 1, a liquid processing apparatus (hereinafter, simply referred to as a liquid processing apparatus) 1 for producing a carbon dioxide-containing beverage according to an embodiment of the present invention is the liquid processing described above with reference to FIG. Like the device 5, the liquid feeding unit T, the heating device H, the cooling device CA, the cooling device CB, and the carbonator CC are mainly configured, but the cooling device CA and the cooling device CB are arranged in a close position, A switching valve VC composed of a valve V3, a valve V4, and a valve V5 is provided in the middle of the liquid feeding pipe PC that connects the cooling device CA and the cooling device CB, and the liquid feeding unit T is connected to the liquid feeding unit T via the valve V4 and the valve V2. A return pipe RA for connection and a return pipe RB for connecting the valve V7 and the valve V5 are provided.
The return pipe RA and the return pipe RB can be connected by opening the valve V5 of the switching valve VC.

次に、本発明の実施の形態に係わる炭酸ガス入り飲料製造用液体の液処理装置1の作用を図1から図3に基づいて説明する。
液処理装置1の製造運転時は、切換え弁VCの弁V3を開、弁V4を閉に、切換え弁VDの弁V6を開、弁V7を閉にして、図示しない上流側の供給元から送液部Tに送液された液体Lが、図1に太線で示すように、ポンプPによって送液部Tから矢印F2の方向に送液配管PA、加熱機器H、送液配管PB、冷却機器CA、切換え弁VCを伴う送液配管PC、冷却機器CBへ、さらに、矢印F4の方向に切換え弁VDを伴う送液配管PDを介してカーボネータCCへ送液され、前記カーボネータCCで炭酸ガスが所定量吸収されて滅菌済の炭酸ガス入り飲料となって、前記カーボネータCCからポンプP2によって送液配管PPを介して図示しない下流の充填装置へ送液される。
即ち、液体Lは、加熱機器Hでの高圧下の高温加熱により微生物が滅菌処理され、常温への冷却処理を経て、炭酸ガス吸収に適した常温以下の低温度まで冷却処理されて、カーボネータCCで所定濃度の炭酸ガスを吸収して炭酸ガス入り飲料となった後、下流側の充填装置でびん或いは缶等の容器に所定量充填される。
Next, the operation of the liquid treatment apparatus 1 for producing liquid containing carbon dioxide gas according to the embodiment of the present invention will be described with reference to FIGS.
During the manufacturing operation of the liquid processing apparatus 1, the valve V3 of the switching valve VC is opened, the valve V4 is closed, the valve V6 of the switching valve VD is opened, and the valve V7 is closed. The liquid L fed to the liquid part T is fed by the pump P from the liquid feed part T in the direction of the arrow F2, as shown by a thick line in FIG. The liquid is fed to the carbonator CC via the liquid feed pipe PC with the switching valve VD in the direction of the arrow F4 to the CA, the liquid feed pipe PC with the switching valve VC, and the cooling device CB. A predetermined amount is absorbed and becomes a sterilized carbon dioxide-containing beverage, which is fed from the carbonator CC to the downstream filling device (not shown) via the liquid feeding pipe PP by the pump P2.
That is, the liquid L is sterilized by microorganisms by high-temperature heating under high pressure in the heating device H, cooled to room temperature, cooled to a low temperature below room temperature suitable for carbon dioxide absorption, and then the carbonator CC After absorbing carbon dioxide of a predetermined concentration to obtain a drink containing carbon dioxide, a predetermined amount is filled in a container such as a bottle or a can with a downstream filling device.

ここで、製造運転時に、前記充填装置等の下流側機器の運転が一旦停止となる事態が生じた場合には、前記液体Lは、弁V1を閉、弁V2を開として、また、切換え弁VCの弁V4を開、弁V3を閉、弁V5を閉として、図2に太線で示すように、ポンプPによって送液部Tから図示矢印F2の方向に送液配管PA、加熱機器H、送液配管PB、冷却機器CA、送液配管PC、切換え弁VCへ、さらに、切換え弁VCから図示矢印FAの方向にリターン配管RAを経て送液部Tへのループで循環されて、循環待機状態となり、切換え弁VCから下流側の冷却機器CBへの送液が停止される。   Here, when the operation of the downstream equipment such as the filling device is temporarily stopped during the manufacturing operation, the liquid L is closed with the valve V1 and the valve V2 open. The valve V4 of the VC is opened, the valve V3 is closed, the valve V5 is closed, and as shown by a thick line in FIG. 2, the liquid feed pipe PA, the heating device H, Circulated to the liquid feeding pipe PB, the cooling device CA, the liquid feeding pipe PC, the switching valve VC, and further circulated in a loop from the switching valve VC to the liquid feeding section T via the return pipe RA in the direction of the arrow FA shown in the figure. Then, the liquid feeding from the switching valve VC to the downstream cooling device CB is stopped.

また、液処理装置1は、製造運転の前或いは後は、洗浄または滅菌用液体Sが送液部T内に満たされ、弁V1を閉、弁V2を開として、また、切換え弁VCの弁V3を開、弁V5を開、弁V4を閉として、前記送液部T内に満たされた洗浄または滅菌用液体Sが、図3に太線で示すように、ポンプPによって送液部Tから図示矢印F2の方向に送液配管PA、加熱機器H、送液配管PB、冷却機器CA、切換え弁VCを伴った送液配管PC、冷却機器CB、送液配管PD,切換え弁VDから図示矢印FBの方向にリターン配管RBを弁V5へ、さらに弁V2経由でリターン配管RAを送液部Tへのループで、加熱機器Hで適宜温度に加熱されて所定時間循環され、前記液体Lの通路が所定条件で洗浄または滅菌される。
なお、前記説明では弁V4を閉にした場合を説明したが、弁V4を適宜流量調整できる開度で開にして、洗浄または滅菌用液体Sを送液配管PCから冷却機器CB,送液配管PD、切換え弁VD、リターン配管RB、弁V5経由リターン配管RAへ送液するとともに、送液配管PCから弁V4を経由してリターン配管RAへ送液するというように送液を分岐するとしてもよい。
In addition, before or after the manufacturing operation, the liquid processing apparatus 1 is filled with the cleaning or sterilizing liquid S in the liquid feeding portion T, the valve V1 is closed, the valve V2 is opened, and the valve of the switching valve VC. The V3 is opened, the valve V5 is opened, and the valve V4 is closed, and the cleaning or sterilizing liquid S filled in the liquid feeding part T is discharged from the liquid feeding part T by the pump P as shown by a bold line in FIG. In the direction of the illustrated arrow F2, the arrow from the liquid feeding pipe PA, the heating equipment H, the liquid feeding pipe PB, the cooling equipment CA, the liquid feeding pipe PC with the switching valve VC, the cooling equipment CB, the liquid feeding pipe PD, and the switching valve VD. The return pipe RB is routed to the valve V5 in the direction of FB, and the return pipe RA is looped to the liquid feeding section T via the valve V2, and is heated to an appropriate temperature by the heating device H and circulated for a predetermined time, and the passage of the liquid L Is washed or sterilized under predetermined conditions.
In the above description, the valve V4 is closed. However, the valve V4 is opened at an opening that allows the flow rate to be appropriately adjusted, and the cleaning or sterilizing liquid S is supplied from the liquid supply pipe PC to the cooling device CB and the liquid supply pipe. Even if the liquid feeding is branched such that the liquid is fed to the return pipe RA via the PD, the switching valve VD, the return pipe RB, and the valve V5, and the liquid is fed from the liquid feeding pipe PC to the return pipe RA via the valve V4. Good.

前記説明のように、液体Lの循環待機の場合に液体Lが冷却機器CBを経由しないので、加熱機器Hでの加熱の際の熱エネルギーが少なくてすみ、さらに、冷却機器CBを冷却機器CAに近い配置として、切換え弁VCを設けることにより、冷却機器CB周りのための液体通路の洗浄または滅菌用液体Sの加熱装置を設ける必要がなく、また、加熱機器Hによる前記洗浄または滅菌用液体Sの加熱が有効利用されるので、効率的である。   As described above, since the liquid L does not pass through the cooling device CB when the liquid L is in circulation standby, less heat energy is required when heating with the heating device H, and the cooling device CB is replaced with the cooling device CA. By providing the switching valve VC as an arrangement close to the above, there is no need to provide a liquid passage cleaning or sterilizing liquid S heating device around the cooling device CB, and the cleaning or sterilizing liquid by the heating device H is not necessary. Since heating of S is effectively used, it is efficient.
