An output signal corresponding to the temperature of the detection unit 50S is output.

The thermocouple 50 is inserted into the thermocouple accommodating portion 231 (sensor accommodating portion) of the basket 23. As a result, when the first lid portion 21 is attached to the container body 20 of the pressure vessel 2 together with the basket 23, the detection portion 50S of the thermocouple 50 is arranged in the basket 23 in the processing space S.

With reference to FIG. 4, the length of the processing space S of the pressure vessel 2 in the axial direction is L, and the axial direction from the end of the processing space S on the first lid portion 21 side to the detection portion 50S of the thermocouple 50. When the distance in is M, the relationship of 0 <M / L <1 is satisfied. In this embodiment, the distance M is also equal to the length of the thermocouple accommodating portion 231.

When performing isotropic pressure pressurization treatment on an object to be processed, first, a container body 20, a first lid 21, a basket 23, a thermocouple 50, and a pressurizing device body 100 are prepared. (Preparation process). As described above, the lid unit 2S is formed by connecting (fixing) the first lid portion 21 and the basket 23 to each other in advance (container container fixing step). The operator inserts an object to be processed such as food into the basket 23 of the lid unit 2S (accommodation step). Further, the control unit 35 adjusts the temperature of the lid unit 2S at the standby position Q by controlling the preheating heater 33 (temperature adjustment step). As a result, the object to be processed contained in the basket 23 can be kept warm. In another embodiment, the preheating heater 33 may not be provided. Then, the control unit 35 drives the first lid cylinder 61 based on the command operation of the operator, and the lid unit 2S is mounted on the container body 20. As a result, the pressure vessel 2 (excluding the second lid 22) is assembled (pressure vessel assembly step).

Next, the control unit 35 drives the moving mechanism 60, so that the container body 20 including the lid unit 2S is installed at the pressurizing position P in the press frame 10 (pressurizing process step). At the pressurizing position P on the rail 13, the second lid portion 22 is arranged so as to face the container body 20.

When the container body 20 is arranged at the pressurizing position P, the second lid cylinder 12 extends, and the second lid portion 22 is attached to the container body 20 via a pressure receiving plate (not shown). As a result, the processing space S is sealed.

Next, the control unit 35 controls the water supply / drainage unit 31, and hot water (pressure medium) is supplied from the water supply / drainage unit 31 into the processing space S through the right frame 10B and the second lid 22. The hot water is filled until the treatment space S is filled. Next, the control unit 35 controls the pump unit 32 to pressurize the hot water in the processing space S (isotropic pressure pressurization treatment, pressurization treatment step). At this time, since the volume of hot water in the treatment space S is reduced by pressurization, water at room temperature is additionally replenished. By continuing the isotropic pressure pressurization treatment for a predetermined time, a bactericidal action or the like on the object to be treated in the basket 23 is exhibited.

In the present embodiment, as described above, hot water is supplied into the pressure vessel 2 before pressurization, and water at room temperature is replenished at the time of pressurization. This is because it is not preferable to replenish the pressurized high-temperature water (warm water) due to the characteristics of the seal member (not shown) in the pressure vessel 2. In this case, the temperature inside the pressure vessel 2 at the time of pressurization is lower than that before the pressurization. Therefore, it is important to detect the temperature in the processing space S by the thermocouple 50 during pressurization.

When the isotropic pressure pressurization process is completed, the process space S is depressurized. At this time, hot water is discharged from the drain valve 211 of the first lid portion 21. Hot water is also discharged through the water supply / drainage channel 221 of the second lid portion 22. The second lid cylinder 12 detaches the second lid portion 22 from the container body 20 via the pressure receiving plate. After that, the container body 20 including the lid unit 2S is moved to the standby position Q again by the moving mechanism 60 (FIG. 1). Then, the lid unit 2S is taken out from the container body 20 by the first lid cylinder 61, and the object to be processed after the pressurization treatment is taken out from the basket 23 of the lid unit 2S (pressure vessel disassembling step).

As described above, the temperature of the object to be processed in the basket 23 may be adjusted by the preheating heater 33 before the lid unit 2S is attached to the container body 20 (temperature adjustment step). At this time, the temperature of the object to be processed during the temperature adjustment step may be monitored by the thermocouple 50 (adjustment temperature monitoring step).

Further, as shown in FIG. 2, a plurality of lid units 2S may be prepared for one container body 20. That is, one lid unit 2S including one basket 23 and one first lid portion 21 and another lid unit 2S including the other basket 23 and the other first lid portion 21 are prepared. Then, the pressurizing treatment step for the pressure vessel 2 including the one lid unit 2S and the temperature adjusting step for the other basket 23 or the other lid unit 2S including the other basket 23 are performed in parallel. May be executed.

As described above, in the present embodiment, the thermocouple 50 makes it possible to monitor the temperature of the object to be processed during the pressurization treatment. Therefore, even if the object to be treated is easily affected by temperature such as food, the pressure treatment can be stably performed. Further, since the detection unit 50S of the thermocouple 50 is arranged in the processing space S, the temperature of the object to be processed can be detected with high accuracy. Further, since the thermocouple 50 is supported by the first lid portion 21, the electrical wiring of the thermocouple 50 can be extended to the outside of the pressure vessel 2 through the inside of the first lid portion 21. Therefore, the need to route the electrical wiring around the container body 20 is reduced.

Further, in the present embodiment, when the first lid portion 21 is attached to the container body 20 of the pressure vessel 2, the detection portion 50S is arranged in the basket 23. Therefore, since the detection unit 50S of the thermocouple 50 is arranged in the processing space S, particularly in the basket 23, the temperature of the object to be processed can be detected more accurately.

Further, in the present embodiment, the basket 23 has a thermocouple accommodating portion 231 that internally receives the thermocouple 50 in connection with the connection between the first lid portion 21 and the basket 23. Therefore, since the thermocouple 50 is housed in the thermocouple accommodating portion 231 in the basket 23, it is possible to prevent the thermocouple 50 from being damaged by interference with the object to be processed.

Further, in the present embodiment, since the first lid portion 21 and the basket 23 are integrally mounted on the container body 20, the detection portion 50S of the thermocouple 50 can be easily arranged in the processing space S and in the basket 23. Can be done. Further, it is possible to monitor the temperature of the object to be processed in the basket 23 even before the lid unit 2S is attached to the container body 20. Further, since the relative positions of the first lid portion 21, the basket 23, and the thermocouple 50 are fixed, it is not necessary to attach / detach the thermocouple 50 for each treatment, and damage to the thermocouple 50 is prevented, and the thermocouple 50 is prevented from being damaged. The position of can be maintained stably.

Further, in the present embodiment, as described above, the relationship of 0 <M / L <1 is satisfied. Therefore, since the detection unit 50S of the thermocouple 50 is arranged in the processing space S, the temperature of the object to be processed can be detected more accurately.

Further, in the present embodiment, the thermocouple 50 is used as a temperature sensor for detecting the temperature in the processing space S. Therefore, the temperature of the object to be processed can be easily detected by the simple thermocouple 50.

In the present embodiment, the control unit 35 receives the output signal of the thermocouple 50 from the above-mentioned process of accommodating the object to be processed to the process of disassembling the pressure vessel through the pressurizing process, thereby processing the inside of the basket 23. The temperature of an object can be measured. Generally, when hot water is used in the CIP device 1, the temperature of the basket 23 rises in the preheating stage of the basket 23 by the preheating heater 33. After that, after hot water is supplied into the pressure vessel 2, the temperature inside the pressure vessel 2 drops in the pressurizing step. On the other hand, when cold water is used in the CIP device 1, the pressure vessel 2 is pre-cooled at the standby position Q (temperature adjustment). After that, after cold water is supplied into the pressure vessel 2, the temperature inside the pressure vessel 2 rises in the pressurizing step. In the present embodiment, such a temperature change in the pressure vessel 2 (and in the basket 23) can be accurately detected by the thermocouple 50.
