In addition, the basket body 230 may be provided with a bidirectional check valve, which allows the pressure medium to flow between the processing space S and the inside of the basket body 230.

The thermocouple accommodating part 231 accommodates the thermocouple 50 described later in connection with the connection of the first lid part 21 and the basket 23. The thermocouple accommodating part 231 has a circular tube shape, and both ends thereof are open. The base end of the thermocouple accommodating portion 231 is fixed to the side surface of the basket body 230 on the first cover portion 21 side. The front end of the thermocouple accommodating part 231 is located inside the basket body 230.

The opening and closing part 232 is arranged on the upper surface of the basket body 230 so as to be openable and closable. The operator opens and closes the opening and closing portion 232, thereby allowing the object to be processed into and out of the basket body 230.

The pair of holes 233 are each opened on the side surface of the basket body 230 on the first cover 21 side. The hole 233 receives the aforementioned connecting bolt 214.

As shown in FIG. 4, in this embodiment, after a pair of connecting bolts 214 are inserted into a pair of holes 233, a nut (not shown) is screwed on the tip of the connecting bolt 214, thereby connecting the bolt 214 with the hole. 233 interconnected. As a result, the first lid 21 and the basket 23 can be integrally attached to the container body 20 of the pressure container 2. Then, inside the pressure vessel 2, the first cover 21 is connected to the basket 23 in the processing space S. In addition, in FIG. 2, a plurality of cover units 2S (first cover 21, basket 23) are arranged in the standby position Q.

In addition, the CIP device 1 has a thermocouple 50 (temperature sensor). The thermocouple 50 is supported by the first cover 21, and has a detection unit 50S arranged in the processing space S because the first cover 21 is mounted on the container body 20 of the pressure vessel 2, and outputs an output corresponding to the temperature of the detection unit 50S Output signal.

The thermocouple 50 is inserted into the thermocouple housing part 231 (sensor housing part) 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.

4, the axial length of the processing space S of the pressure vessel 2 is L, and the axial distance of the processing space S from the end on the side of the first cover 21 to the detecting portion 50S of the thermocouple 50 is In the case of M, the relationship of 0<M/L<1 is met. In this embodiment, the distance M is also equivalent to the length of the thermocouple accommodating part 231.

In the case of applying isostatic pressure to the processed object, first prepare: the container body 20, the first cover 21, the basket 23, the thermocouple 50, and the pressurizing device body 100 (preparation process). As described above, the first lid 21 and the basket 23 are connected (fixed) to each other in advance, thereby forming the lid unit 2S (container fixing process). The worker inserts processed objects such as food into the basket 23 of the lid unit 2S (containment process). In addition, the control unit 35 controls the preheating heater 33 to adjust the temperature of the cover unit 2S at the standby position Q (temperature adjustment process). As a result, the to-be-processed object contained in the basket 23 can be kept warm. Moreover, in other embodiments, the heater 33 for preheating may not be provided. Then, based on the operator's command operation, the control unit 35 drives the first cover cylinder 61 to attach the cover unit 2S to the container body 20. As a result, the pressure vessel 2 (except for the second lid 22) is assembled (pressure vessel assembly process).

Next, by causing the control unit 35 to drive the moving mechanism 60, the container body 20 including the lid unit 2S is set at the pressurizing position P in the press frame 10 (pressurizing process). At the pressure position P on the rail 13, the second lid portion 22 is arranged to face the container body 20.

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

Next, the control unit 35 is caused to control the water supply and drainage unit 31, and the hot water (pressure medium) is supplied from the water supply and drainage unit 31 through the right frame 10B and the second cover 22 into the processing space S. The warm water is filled until the processing space S is filled. Next, the control unit 35 controls the pump unit 32 to pressurize the warm water in the processing space S (isostatic pressure processing, pressure processing process). At this time, the volume of warm water in the processing space S is reduced by pressurization, and water at room temperature is additionally replenished. The equalizing and pressurizing treatment is continued for a predetermined period of time, thereby exerting a sterilization effect on the processed objects in the basket 23 and the like.

In addition, in this embodiment, as described above, warm water is supplied into the pressure vessel 2 before pressurization, and water at room temperature is replenished during pressurization. This is because it is not suitable for replenishing pressurized high-temperature water (warm water) due to the characteristics of the sealing member (not shown) in the pressure vessel 2. In this case, the temperature in the pressure vessel 2 during pressurization is lower than before pressurization. Therefore, it is important to use the thermocouple 50 to detect the temperature in the processing space S during pressurization.

After the equal pressure equalization and pressurization treatment is completed, the treatment space S is subjected to a decompression treatment. At this time, the warm water is drained from the drain valve 211 of the first cover 21. In addition, the warm water is also discharged through the water supply and drainage channel 221 of the second cover 22. The second cover cylinder 12 is made to pass through the pressure plate to detach the second cover 22 from the container body 20. 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 pressure-treated object is taken out from the basket 23 of the lid unit 2S (pressure vessel disassembly process).

In addition, as described above, before attaching the lid unit 2S to the container body 20, the temperature of the object to be processed in the basket 23 may be adjusted by the heater 33 for preheating (temperature adjustment process). At this time, the temperature of the object to be processed in the above-mentioned temperature adjustment process may be monitored by the thermocouple 50 (adjustment temperature monitoring process).

In addition, as shown in FIG. 2, a plurality of lid units 2S may be prepared for one container body 20. That is, one cover unit 2S including one basket 23 and one first cover 21, and another cover unit 2S including other baskets 23 and other first cover 21 are prepared. Then, the pressure treatment process for the pressure vessel 2 containing the one lid unit 2S, and the temperature adjustment process for the other basket 23 or the other lid unit 2S containing the other basket 23 are simultaneously performed.

In this embodiment as described above, the temperature of the object to be processed in the pressurization process can be monitored by the thermocouple 50. Therefore, even if the to-be-processed object is a food, etc., which is easily affected by temperature, the pressure treatment can be stably performed. Furthermore, since the detection part 50S of the thermocouple 50 is arrange|positioned in the processing space S, the temperature of a to-be-processed object can be detected accurately. In addition, since the thermocouple 50 is supported by the first cover 21, the circuit wiring of the thermocouple 50 can be drawn to the outside of the pressure vessel 2 through the inside of the first cover 21. Therefore, the need to pull the above-mentioned circuit wiring to the container body 20 is reduced.

In addition, 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 part 50S of the thermocouple 50 is arrange|positioned in the processing space S, especially in the basket 23, it can detect the temperature of a to-be-processed object more accurately.

In addition, in the present embodiment, the basket 23 has a thermocouple accommodating portion 231 that accommodates the thermocouple 50 in the interior along with the connection of the first lid portion 21 and the basket 23. Therefore, the thermocouple 50 is accommodated in the thermocouple accommodating part 231 in the basket 23, so that the thermocouple 50 can be prevented from being damaged due to interference with the object to be processed.

Furthermore, in the present embodiment, the first cover 21 and the basket 23 are integrally attached to the container body 20, so the detection part 50S of the thermocouple 50 can be easily arranged in the basket 23 in the processing space S. Furthermore, before the lid unit 2S is mounted on the container body 20, the temperature of the processed object in the basket 23 can be monitored. In addition, the relative positions of the first cover 21, the basket 23, and the thermocouple 50 are fixed. Therefore, it is not necessary to attach and detach the thermocouple 50 every time to prevent damage to the thermocouple 50 and maintain the position of the thermocouple 50 stably.

In addition, in the present embodiment, as described above, the relationship of 0<M/L<1 is satisfied. Therefore, since the detection part 50S of the thermocouple 50 is arrange|positioned in the processing space S, the temperature of a to-be-processed object can be detected more accurately.

Furthermore, in this embodiment, the thermocouple 50 is used as a temperature sensor for detecting the temperature in the processing space S. Therefore, with the simple thermocouple 50, the temperature of the processed object can be easily detected.

Furthermore, in this embodiment, the control unit 35 receives the output signal of the thermocouple 50 during the period from the above-mentioned object storage process through the pressurization process to the pressure vessel disassembly process, so that the inside of the basket 23 can be measured. The temperature of the processed material. Generally, when warm water is used in the CIP device 1, first, the temperature of the basket 23 is increased by the heater 33 for preheating in the preheating stage of the basket 23. After that, after supplying warm water into the pressure vessel 2, the temperature in the pressure vessel 2 is lowered in the pressurization stage. On the other hand, when the CIP device 1 uses cold water, the pressure vessel 2 is cooled in advance (temperature adjustment) at the standby position Q. After that, after supplying cold water into the pressure vessel 2, the temperature in the pressure vessel 2 is increased in the pressurization stage. In the present embodiment, the thermocouple 50 can accurately detect such temperature changes in the pressure vessel 2 (and the basket 23). Moreover, in the temperature adjustment process performed before the pressurization process, the control unit 35 also receives the output signal of the thermocouple 50, so that the temperature of the processed object in the basket 23 before the pressurization process can be measured.

And, as mentioned above, in this embodiment, the 1st cover part 21 and the basket 23 are connected beforehand, and the cover unit 2S (accommodating unit for equal pressure processing) is comprised.

According to the structure of the cover unit 2S, by attaching the cover unit 2S to the container body 20, the detection part 50S of the thermocouple 50 and the processed object can be easily arranged in the processing space S. In addition, as shown in FIG. 2, a plurality of cover units 2S are prepared in advance, and the pressing position P is sequentially (alternately) conveyed, thereby efficiently performing the pressing treatment on the object to be processed.
