[0002] Conventionally, there is a known pressurizing device (isotropic pressurizing device) for performing pressure treatment (HPP treatment: High pressure Processing) on ​​a processed object for the purpose of sterilizing microorganisms attached to the processed object such as food. In such a pressurizing device, the processed object is contained in a cylindrical pressure container, and the pressure treatment is performed by sealing a pressure medium in the pressure container. Compared with high-temperature heating treatment, this pressure treatment is effective because it causes less damage to the taste, texture, and flavor of the food, but it is difficult to sterilize bacteria that are resistant to pressure (for example, spore fungi).

[0003] In this regard, Patent Document 1 discloses a technique for killing spore fungi by combining the above-mentioned pressure treatment with a heat treatment at 100°C or lower. Specifically, Patent Document 1 discloses a technique for killing spore fungi by heating the object at 100 kg / cm2 at a temperature of 100°C or lower. 2 After the above hydrostatic pressure treatment, a heat treatment is performed at a temperature of 55°C to 100°C for more than 1 minute.

[0017] Hereinafter, a pressurizing device 1 (cold isotropic pressurizing device, isotropic pressurizing device) according to an embodiment of the present invention will be described with reference to the drawings. Figure 1 It is a perspective view of a pressurizing device 1 according to one embodiment of the present invention. Figure 2 It is a cross-sectional view of the pressure container 2 and the storage container 50 of the pressurizing device 1 according to the present embodiment. Figure 3 1 is a cross-sectional view of a storage container 50 of the pressurizing device 1 according to the present embodiment. The pressurizing device 1 performs isotropic pressurization on the workpiece W using a pressure medium.

[0018] In the following description, the object W to be processed is food, but the object W may be a product other than food (eg, beverage) or an inorganic substance (inorganic powder) such as metal powder or ceramic powder.

[0019] A pressurizing device 1 according to one embodiment of the present invention includes a pressure container 2 ( Figure 2 )、the storage container 50 and the pressurizing device body 100 ( Figure 1 The pressurizing device body 100 includes a pressurizing frame 10 , a carry-in rail 11 , a carry-out rail 12 , a moving rail 13 , a water supply and drainage unit 31 (pressure medium supply mechanism), a pump unit 32 (pressurizing mechanism), and a control unit 35 .

[0020] The pressure container 2 accommodates the processed object W therein and performs isotropic pressure treatment on the processed object W. The pressure container 2 includes a container body 20, a first cover 21, and a second cover 22. The pressure container 2 is formed of a metal material such as stainless steel in order to have high pressure resistance.

[0021] The container body 20 includes a cylindrical inner circumferential surface formed around a central axis CL1 extending in the horizontal direction. A processing space S1 defined by the inner circumferential surface is formed inside the container body 20, and both ends of the inner circumferential surface in the axial direction are opened ( Figure 2 ).

[0022] The first cover 21 and the second cover 22 are respectively installed at the two ends of the container body 20 in the axial direction to seal the processing space S1. The first cover 21 has a sealing portion 21A and a flange 21B, and the second cover 22 has a sealing portion 22A and a flange 22B. The sealing portion 21A and the sealing portion 22A are respectively inserted into the first opening 20A and the second opening 20B of the container body 20 ( Figure 1 ), the processing space S1 is sealed. The flange 21B and the flange 22B are in contact with both ends of the container body 20 in the axial direction.

[0023] The first cover 21 has a water supply and drainage channel 211, and the second cover 22 has a water supply and drainage channel 221. The water supply and drainage channel 211 connects the outside of the first cover 21 with the processing space S1, and the pressure medium after the pressurization treatment is discharged from the processing space S1 through the water supply and drainage channel 211. In addition, the water supply and drainage channel 221 is connected to the water supply and drainage assembly 31 and the pump assembly 32 through a flow path not shown in the figure, and the pressure medium flows into the processing space S1 through the water supply and drainage channel 221, and the pressure medium is discharged from the processing space S1 through the water supply and drainage channel 221. The water supply and drainage channel 211 and the water supply and drainage channel 221 are provided with valves not shown in the figure that can be opened and closed as needed.

[0024] The storage container 50 stores the processed object W and is arranged in the processing space S1 ( Figure 2 In this embodiment, a storage space S2 ( Figure 2 ).

[0025] Pressure frame 10 ( Figure 1 ) has the function of supporting the axial force acting on the two end covers of the pressure container 2. The pressure frame 10 has a frame structure, and if the pressure container 2 is arranged at the pressurization position P in the frame, the processed object W in the pressure container 2 is subjected to isotropic pressurization treatment.

[0026] The moving guide rail 13 guides the container body 20 so that the container body 20 of the pressure container 2 can move between the pressurizing position P and the standby position Q. The container body 20 is driven by a driving force of a driving mechanism (not shown) to move between the pressurizing position P and the standby position Q. Figure 1 As shown in FIG. 1 , the standby position Q is a position away from the pressurizing position P. In addition, the first cover portion 21 and the second cover portion 22 of the pressure container 2 are always arranged at the pressurizing position P. If the container body 20 is arranged at the pressurizing position P, the driving cylinder (not shown) moves the first cover portion 21 and the second cover portion 22 in the axial direction, and Figure 2 As shown, it is installed at both ends of the container body 20.

[0027] The carrying-in guide 11 guides the storage container 50 toward the inside of the container body 20 waiting at the waiting position Q before the pressurization process. On the other hand, the carrying-out guide 12 guides the storage container 50 so as to be extracted from the container body 20 moved to the waiting position Q after the pressurization process.

[0028] The water supply and drainage unit 31 includes a tank 31A, and supplies a pressure medium to the processing space S1 of the pressure container 2. In the present embodiment, water or hot water is used as the pressure medium.

[0029] The pump unit 32 pressurizes the pressure medium introduced into the processing space S1. In the present embodiment, the pressure medium is supplied to the processing space S1 and the pump unit 32 pressurizes the pressure medium.

[0030] The control unit 35 controls the operation of the water supply and drainage unit 31, the pump unit 32, the driving mechanism, and the driving cylinder. The control unit 35 has an operation panel (not shown).

[0031] Reference Figure 3 The storage container 50 includes a storage container body 501 , a lid 502 (opening and closing member), a first check valve 503 , a second check valve 504 , and a sealing member 505 .

[0032] The storage container body 501 is the main body of the storage container 50, and is in the cylindrical shape formed around the central axis CL2. The storage space S2 of the cylindrical inner peripheral surface of the storage container body 501 is defined and accommodates the processed object W in the inside of the storage container body 501. In addition, in the storage container body 501, an end is opened in the axial two ends of the storage container body 501 to form a peristome. The peristome allows the processed object W to pass through so that the processed object W is configured in the storage space S2. In other words, the operator can drop the processed object W into the storage space S2 through the peristome.

[0033] The cover 502 is mounted on the axial end of the storage container body 501 to open and close the opening. A plurality of bolt insertion portions 502A are formed on the cover 502. Figure 3 As shown, the cover 502 is fixed to the storage container body 501 by tightening the fastening bolt 506 inserted into the bolt insertion portion 502A and tightening it in the bolt hole (not shown) opened in the cover 502 and the storage container body 501. The sealing member 505 exists in the joint portion of the storage container body 501 and the cover 502, and prevents the pressure medium from flowing between the processing space S1 and the storage space S2 through the joint portion.

[0034] In addition, the cover 502 is formed with a first flow path L1 and a second flow path L2. The first flow path L1 and the second flow path L2 connect the outside of the storage container 50 (in Figure 2 The processing space S1 and the receiving space S2 are connected to each other, allowing the pressure medium to flow.

[0035] The first check valve 503 is disposed in the first flow path L1. When the pressure of the processing space S1 is higher than the pressure of the receiving space S2, the first check valve 503 allows the flow of the pressure medium from the processing space S1 to the receiving space S2 in the first flow path L1 while blocking the flow of the pressure medium from the receiving space S2 to the processing space S1 in the first flow path L1. On the other hand, when the pressure of the processing space S1 is lower than the pressure of the receiving space S2, the first check valve 503 blocks the flow of the pressure medium between the processing space S1 and the receiving space S2 in the first flow path L1 and seals the receiving space S2.

[0036] The second check valve 504 is disposed in the second flow path L2. When the pressure of the receiving space S2 is higher than the pressure of the processing space S1, the second check valve 504 allows the flow of the pressure medium from the receiving space S2 to the processing space S1 in the second flow path L2 while blocking the flow of the pressure medium from the processing space S1 to the receiving space S2. On the other hand, when the pressure of the processing space S1 is higher than the pressure of the receiving space S2, the second check valve 504 blocks the flow of the pressure medium between the processing space S1 and the receiving space S2 in the second flow path L2 and seals the receiving space S2.

[0037] In addition, in the present embodiment, the pressure of the processing space S1 and the receiving space S2 being equal means, for example, that the pressure difference between the two is less than 0.3 MPa (check valve operating threshold). The check valve operating threshold can be set according to the use conditions of the first check valve 503 and the second check valve 504. In addition, as described later, the pressure of the processing space S1 is set to 600 MPa during the pressurized treatment, so the state in which the pressure difference between the processing space S1 and the receiving space S2 is less than the check valve operating threshold can be regarded as the state in which the pressure of the processing space S1 and the pressure of the receiving space S2 are equal to each other.

[0038] In addition, in the present embodiment, the storage container body 501 and the cover 502 of the storage container 50 are formed of a material having a lower thermal conductivity than the pressure container 2. Specifically, the storage container body 501 and the cover 502 may be formed of vinyl chloride, MC nylon, Teflon (registered trademark), etc. In addition, these materials may be used in part of the storage container body 501 and the cover 502. According to this structure, the heat preservation property of the storage container 50 can be maintained at a high level. On the other hand, as described above, the pressure container 2 is formed of a metal material having high pressure resistance in order to perform a pressurization process.

[0039] When the isotropic pressure treatment is performed on the object to be processed W, the pressure vessel 2, the storage container 50, and the pressurizing device body 100 are first prepared (preparation step). As described above, the container body 20 of the pressure vessel 2 is arranged at the standby position Q on the moving guide rail 13, and the first cover 21 and the second cover 22 of the pressure vessel 2 are arranged on the pressure frame 10. In addition, the storage container 50 is arranged on the guide rail 11 for carrying in. The operator stores the object to be processed W such as food in the storage container body 501 through the opening of the storage container body 501 in the state where the cover 502 is removed (processed object storage step). In addition, if the operator installs the cover 502 on the storage container body 501 and closes the opening of the storage container body 501, after installing the pipe not shown in the figure at the inlet of the first flow path L1, 80°C hot water (first pressure medium) is supplied to the storage space S2 through the first flow path L1 (processed object storage step). At this time, through the action of the first check valve 503, if the storage space S2 is filled with hot water, the first flow path L1 is closed. Alternatively, hot water may be supplied to the processing space S1 through the opening of the storage container body 501 when the cover 502 is removed from the storage container body 501. Figure 3 The posture of the storage container body 501 is changed so that the central axis CL2 of the storage container body 501 is oriented in the up-down direction and the opening of the storage container body 501 is oriented upward.

[0040] Next, the operator inserts the storage container 50 into the container body 20 along the carrying-in guide rail 11 (storage container placement step). In addition, the operator operates the control unit 35 to place the container body 20 along the moving guide rail 13 at the pressurizing position P in the pressure frame 10. At the pressurizing position P on the moving guide rail 13, the first cover 21 and the second cover 22 are arranged to face the container body 20. Next, when the container body 20 is arranged at the pressurizing position P, the drive cylinder (not shown) is extended, and the first cover 21 and the second cover 22 are respectively installed on the container body 20 ( Figure 2 ). As a result, the processing space S1 becomes sealed.

[0041] Next, the control unit 35 receives the operator's operation command to control the water supply and drainage assembly 31, and water (the second pressure medium) at room temperature (20°C) is supplied from the water supply and drainage assembly 31 to the processing space S1 of the pressure vessel 2. The amount of the water is, for example, 200 L. The temperature of the water is set to be lower than the temperature of the hot water put into the storage space S2. The water is filled until the processing space S1 is full.

[0042] Next, the control unit 35 controls the pump assembly 32 to pressurize the water in the processing space S1 (isotropic pressurization treatment, pressurization treatment step). At this time, since the volume of the water in the processing space S1 is reduced due to pressurization, water at room temperature (for example, 32L) is added. During pressurization, the pressure of the processing space S1 is set to about 600MPa. On the other hand, the receiving space S2 in the receiving container 50 is set to atmospheric pressure when pressurization begins. Therefore, based on the pressure difference between the processing space S1 and the receiving space S2, the first check valve 503 opens the first flow path L1, allowing water (the second pressure medium) to flow from the processing space S1 to the receiving space S2 through the first flow path L1. In other words, when the inflow channel of water from the processing space S1 to the receiving space S2 during pressurization is limited to the first flow path L1 opened by the first check valve 503, the processed object W in the receiving container 50 is subjected to isotropic pressurization treatment. Soon, if the pressures of the processing space S1 and the receiving space S2 are equal to each other, in other words, if the pressure of the receiving space S2 reaches about 600 MPa, the first check valve 503 closes the first flow path L1, and the flow of water from the processing space S1 to the receiving space S2 stops. In this way, the first check valve 503 suppresses the replacement of the pressure medium between the processing space S1 and the receiving space S2, and the temperature in the receiving space S2 is maintained at 70°C to 80°C by the heat insulation performance of the receiving container 50 (heat preservation function), and high pressure is applied to the processed object W for a specified time, thereby exerting a high sterilization effect on the processed object W in the receiving container 50.

[0043] If the pressurization treatment is completed, the decompression treatment of the processing space S1 is implemented. Specifically, water is discharged from the water supply and drainage channel 211 of the first cover 21 and the water supply and drainage channel 221 of the second cover 22. At this time, if the water is gradually discharged from the processing space S1, a pressure difference occurs between the processing space S1 and the receiving space S2, and the second flow path L2 is opened by the second check valve 504. As a result, the pressure medium (the water mixed with the hot water initially put into the receiving space S2 and the water added to the processing space S1) is discharged from the receiving space S2 to the processing space S1, the inside of the receiving space S2 is close to the atmospheric pressure, and the pressure vessel 2 is decompressed (decompression treatment step).

[0044] Thereafter, the driving cylinder (not shown) detaches the first cover 21 and the second cover 22 from the container body 20 via the pressure plate. Then, the container body 20 including the storage container 50 is moved to the standby position Q ( Figure 1 Then, the storage container 50 is pulled out from the container body 20 along the guide rail 12 for carrying out, and the processed object W after the pressure treatment is taken out from the storage container 50.

[0045] In addition, a plurality of storage containers 50 may be prepared for one container body 20. In this case, while one storage container 50 is placed in the container body 20 and is pressurized at the pressurizing position P, the storage container 50 on the loading guide rail 11 may be loaded with the processed object W and supplied with hot water (the first pressure medium).

[0046] As described above, in the present embodiment, the storage container 50 has the first flow path L1, the second flow path L2, the first check valve 503, and the second check valve 504. According to this structure, the object to be processed W is stored in the storage space S2 of the storage container 50, and the storage container 50 is arranged in the processing space S1 of the pressure container 2, and the pressure medium is supplied to the processing space S1, thereby isotropically pressurizing the object to be processed W. In particular, the first flow path L1 and the second flow path L2 are provided in the storage container 50, and the first check valve 503 and the second check valve 504 are arranged in each flow path. Therefore, if the pressure medium formed by hot water is supplied to the storage space S2 together with the object to be processed W in advance, and the pressure medium formed by water with a temperature lower than the temperature of the hot water is supplied to the processing space S1 of the pressure container 2 and pressurized, then the pressure medium flows from the processing space S1 to the storage space S2 by the action of the first check valve 503, and the object to be processed W is isotropically pressurized. At this time, since the pressure medium is suppressed from flowing out from the storage space S2 to the processing space S1 by the action of the second check valve 504, the object to be processed W can be subjected to pressure treatment while the temperature in the storage space S2 is maintained close to the temperature of hot water. As a result, the object to be processed W can be subjected to pressure treatment and heat treatment in parallel. In addition, there is no need to fill the pressure medium formed by hot water into the processing space S1 of the pressure vessel 2 in order to perform heat treatment on the object to be processed W, so the necessity of using a material with high heat resistance for the pressure vessel 2 is reduced. If the pressure medium is discharged from the processing space S1 after the pressure treatment is completed, the second check valve 504 allows the pressure medium to flow out from the storage space S2 to the processing space S1 based on the pressure difference between the processing space S1 and the storage space S2. Therefore, the situation where the storage container 50 is damaged due to the pressure difference between the processing space S1 and the storage space S2 is suppressed. As described above, during the pressurization treatment of the processed object W, even if there is a temperature difference of more than 10°C between the pressure medium inside and outside the storage container 50, the processed object W can be pressurized while the storage container 50 is kept warm. In other words, it is not necessary to supply hot water to the processing space S1 in order to perform a heating treatment on the processed object W. Therefore, the pressure container 2 can be designed with emphasis on pressure resistance, and the necessity of designing the pressure container 2 and its surrounding components to be resistant to high temperatures and selecting materials is reduced.

[0047] Furthermore, in the present embodiment, the storage container 50 is formed of a material having a lower thermal conductivity than the pressure container 2. Therefore, since the thermal insulation performance of the storage container 50 is set higher than the thermal insulation performance of the pressure container 2, the heat preservation performance of the storage space S2 during the pressurization process is improved, and the object W can be stably heated. In addition, the necessity of using a material having high heat resistance for the pressure container 2 is reduced, and a material having high pressure resistance can be used.

[0048] In addition, in the present embodiment, the first flow path L1 and the second flow path L2 are respectively arranged on the cover 502 in a manner that allows the pressure medium to flow between the storage space S2 and the processing space S1 through the cover 502. In addition, the first check valve 503 and the second check valve 504 are respectively installed on the cover 502 corresponding to the first flow path L1 and the second flow path L2. Therefore, the processed object W can be easily put into the storage space S2 through the opening of the storage container body 501. In addition, by centrally arranging the first flow path L1, the second flow path L2, the first check valve 503 and the second check valve 504 on the cover 502, the structure of the storage container 50 can be simplified, and the maintenance convenience of the storage container 50 can be improved.

[0049] In addition, in the present embodiment, the cover 502 is mounted on the storage container body 501 in such a manner as to close (seal) the opening of the storage container body 501 in the axial direction. As described above, since the opening is formed at the axial end of the storage container body 501, the rigidity of the storage container body 501 can be maintained higher than when the opening is formed at the axial center of the storage container body 501. In addition, the processed object W and the pressure medium can be easily put into the storage space S2 through the axial end of the storage container body 501, and the airtightness of the storage container 50 can be improved.

[0050] In addition, in this embodiment, the pressurizing device body 100 of the pressurizing device 1 further includes a water supply and drainage assembly 31 for supplying a pressure medium to the processing space S1 of the pressure container 2 and a pump assembly 32 for pressurizing the pressure medium supplied to the processing space S1. Therefore, the processed object W can be subjected to isotropic pressurization treatment in a stable manner.

[0051] The isotropic pressure treatment method for isotropically pressurizing the object W using a pressure medium according to the present embodiment includes the following steps: The isotropic pressure treatment method includes a preparation step, an object storage step, a storage container arrangement step, and a pressure treatment step.

[0052] In the preparation step, a pressure vessel 2 and a storage container 50 are prepared. A processing space S1 capable of receiving a pressure medium is formed inside the pressure vessel 2, and a storage space S2 capable of storing a processed object W is formed inside the storage container 50. The storage container 50 includes a first flow path L1 and a second flow path L2 connecting the storage space S2 and the outside of the storage container 50.

[0053] In the process object storage step, the process object W is stored in the storage space S2 of the storage container 50, and the storage space S2 is filled with a first pressure medium consisting of hot water.

[0054] In the storage container placement step, the storage container 50 including the processed object W is placed in the processing space S1 of the pressure vessel 2 .

[0055] In the pressurization step, a second pressure medium formed by water whose temperature is set lower than that of the hot water is supplied to the processing space S1 of the pressure container 2 and pressurized. While allowing the second pressure medium to flow from the processing space S1 into the receiving space S2 through the first flow path L1, an isotropic pressurization treatment is performed on the processed object W in the receiving container 50.

[0056] According to this method, if the first pressure medium formed of hot water is supplied to the storage space S2 together with the processed object W in the processed object storage step, and the second pressure medium formed of water with a temperature lower than the temperature of the hot water is supplied to the processing space S1 of the pressure container 2 and pressurized in the pressurization step, the second pressure medium flows from the processing space S1 into the storage space S2 through the first flow path L1, and the processed object W is isotropically pressurized. Therefore, the processed object W can be pressurized while the temperature in the storage space S2 is maintained close to the temperature of the hot water. As a result, the processed object W can be pressurized and heated in parallel.

[0057] In addition, in the present embodiment, the preparation step includes a step of preparing a container in which the flow path is formed by a first flow path L1 and a second flow path L2 which are independent of each other, and having a first check valve 503 and a second check valve 504 as the receiving container 50, wherein the first check valve 503 is arranged in the first flow path L1, and when the pressure of the processing space S1 is higher than the pressure of the receiving space S2, the flow of the pressure medium in the first flow path L1 from the processing space S1 to the receiving space S2 is allowed under a state in which the flow of the pressure medium in the first flow path L1 from the receiving space S2 to the processing space S1 is blocked, and when the pressure in the processing space S1 is lower than the pressure in the receiving space S2, the flow of the pressure medium in the first flow path L1 from the receiving space S2 to the processing space S1 is blocked. The second check valve 504 is arranged in the second flow path L2 to prevent the flow of pressure medium between the processing space S1 and the receiving space S2 in the first flow path L1 and to seal the receiving space S2. When the pressure of the receiving space S2 is higher than the pressure of the processing space S1, the flow of pressure medium from the receiving space S2 to the processing space S1 in the second flow path L2 is prevented while preventing the flow of pressure medium from the processing space S1 to the receiving space S2. When the pressure of the processing space S1 is higher than the pressure of the receiving space S2, the flow of pressure medium between the processing space S1 and the receiving space S2 in the second flow path L2 is prevented and the receiving space S2 is sealed.

[0058] In addition, the pressurization treatment step includes the following steps: while limiting the inflow channel of the second pressure medium from the processing space S1 to the storage space S2 during pressurization to the first flow path L1 opened by the first check valve 503, isotropically pressurizing the processed object W in the storage container 50.

[0059] In addition, the isotropic pressurization treatment method also includes a decompression treatment step. After the pressurization treatment step, the second pressure medium is discharged from the processing space S1, and the second flow path L2 is opened by using the second check valve 504 due to the pressure difference generated between the processing space S1 and the receiving space S2, thereby decompressing the pressure container 2 while allowing the pressure medium containing the first pressure medium and the second pressure medium to be discharged from the receiving space S2 to the processing space S1.

[0060] According to this method, the second pressure medium flows from the processing space S1 into the receiving space S2 through the action of the first check valve 503, and the processed object W is isotropically pressurized. At this time, since the first pressure medium is suppressed from flowing out of the receiving space S2 into the processing space S1 through the action of the second check valve 504, the processed object W can be pressurized while the temperature in the receiving space S2 is stably maintained at a temperature close to that of hot water. In addition, if the pressure medium is discharged from the processing space S1 after the pressurization treatment is completed, the second check valve 504 allows the pressure medium to flow out of the receiving space S2 into the processing space S1 based on the pressure difference between the processing space S1 and the receiving space S2. Therefore, the situation in which the receiving container 50 is damaged due to the pressure difference between the processing space S1 and the receiving space S2 is further suppressed.

[0061] In addition, in this embodiment, the preparation step includes the step of preparing a container having a storage container body 501 and a cover 502 as the storage container 50, wherein the storage container body 501 has a cylindrical inner circumferential surface that defines a storage space S2, and is formed with an opening portion that allows the processed object W to pass through so that the processed object W can be arranged in the storage space S2, and the cover portion 502 can open and close the opening portion, and a first flow path L1, a second flow path L2, a first check valve 503 and a second check valve 504 are respectively provided on the cover portion 502.

[0062] Furthermore, the processed object accommodating step includes the steps of accommodating the processed object W in the accommodating space S2 through the opening, filling the accommodating space S2 with the first pressure medium, and closing the opening with the cover 502 .

[0063] According to this method, the processed object W can be easily put into the storage space S2 through the opening of the storage container body 501. In addition, by centrally arranging the first flow path L1, the second flow path L2, the first check valve 503 and the second check valve 504 on the cover 502, the maintenance convenience of the storage container 50 can be improved.

[0064] Furthermore, in the present embodiment, the preparation step includes a step of preparing, as the storage container 50 , a container formed of a material having a lower thermal conductivity than the pressure container 2 .

[0065] In addition, the pressurization treatment step includes the following steps: during the pressurization process, the inflow channel of the second pressure medium from the processing space S1 to the receiving space S2 is limited to the first flow path L1, and the first pressure medium is inhibited from flowing out of the receiving space S2 to the processing space S1, and the receiving space S2 is insulated using the receiving container 50.

[0066] According to this method, the thermal insulation performance of the storage container 50 is set higher than that of the pressure container 2, and the outflow of the first pressure medium from the storage space S2 to the processing space S1 is suppressed, thereby improving the thermal insulation performance of the pressurized storage space S2.

[0067] Moreover, the storage container 50 involved in this embodiment is a storage container for an isotropic pressurizing device that can be detachably installed in a pressure vessel 2 in a pressurizing device 1 that uses a pressure medium to perform isotropic pressurization treatment on a processed object W, wherein the pressure vessel 2 includes a cylindrical inner circumferential surface and a processing space S1 is formed inside that can accommodate the processed object W. The storage container 50 includes: a storage space S; a first flow path L1 connecting the storage space S2 and the processing space S1; a second flow path L2 which is independently provided with the first flow path L1 and connects the storage space S2 and the processing space S1; and a first check valve 503 and a second check valve 504, wherein the first check valve 503 is arranged in the first flow path L1, and allows the pressure medium in the first flow path L1 to flow from the processing space S1 to the storage space S2 while preventing the pressure medium in the first flow path L1 from flowing from the storage space S2 to the processing space S1 when the pressure in the processing space S1 is higher than the pressure in the storage space S2, and the pressure in the processing space S1 is lower than the pressure in the storage space S2. The second check valve 504 is arranged in the second flow path L2. When the pressure of the receiving space S2 is higher than the pressure of the processing space S1, the flow of the pressure medium from the processing space S1 to the receiving space S2 in the second flow path L2 is allowed while the flow of the pressure medium from the processing space S1 to the receiving space S2 in the second flow path L2 is blocked. When the pressure of the processing space S1 is higher than the pressure of the receiving space S2, the flow of the pressure medium between the processing space S1 and the receiving space S2 in the second flow path L2 is blocked and the receiving space S2 is sealed.

[0068] According to this structure, the first flow path L1 and the second flow path L2 are provided in the storage container 50, and the first check valve 503 and the second check valve 504 are arranged in each flow path. Therefore, if a pressure medium formed by, for example, hot water is supplied to the storage space S2 together with the object to be processed W in advance, and a pressure medium formed by water having a temperature lower than that of the hot water is supplied to the processing space S1 of the pressure container 2 and pressurized, the low-temperature pressure medium flows from the processing space S1 into the storage space S2 by the action of the first check valve 503, and the object to be processed W is isotropically pressurized. At this time, since the pressure medium formed by hot water is suppressed from flowing out of the storage space S2 to the processing space S1 by the action of the second check valve 504, the object to be processed W can be pressurized while the temperature in the storage space S2 is kept close to the temperature of the hot water. As a result, the object to be processed W can be pressurized and heated in parallel.

[0069] The pressurizing device 1 (isotropic pressurizing device), the storage container 50 (storage container for isotropic pressurizing device), and the isotropic pressurizing method according to one embodiment of the present invention have been described above, but the present invention is not limited to these embodiments, and the following modified embodiments may be adopted.

[0070] (1) In the above embodiment, the temperature of the hot water (first pressure medium) previously introduced into the storage space S2 of the storage container 50 is set to 80°C, and the temperature of the water (second pressure medium) supplied to the processing space S1 during pressurization is set to 20°C, but the present invention is not limited to this. Assuming that the temperature of the first pressure medium is higher than the temperature of the second pressure medium, the respective temperatures may be adjusted according to the processed object W.

[0071] (2) In the above embodiment, one cover 502 is mounted on the axial end of the storage container 50 and the first flow path L1, the second flow path L2, the first check valve 503 and the second check valve 504 are provided on the cover 502. However, the present invention is not limited to this. Figure 4 1 is a cross-sectional view of a storage container 50A of an isotropic pressurizing device according to a first variant embodiment of the present invention. In the storage container 50A, openings are formed at both ends of the storage container body 501 in the axial direction, and a pair of lids 502 are mounted on the storage container body 501 in a manner to close the openings. Figure 4 The right cover 502 is provided with a first flow path L1 and a first check valve 503. Figure 4 The left cover 502 is provided with a second flow path L2 and a second check valve 504. In this structure, the object W can be isotropically pressurized while maintaining the heat preservation of the storage space S2 of the storage container 50. Figure 4In the embodiment, the first flow path L1, the second flow path L2, the first check valve 503 and the second check valve 504 may be collectively provided in one cover 502. As described above, the opening and the cover 502 formed in the storage container body 501 are not limited to one each, and a plurality of them may be provided.

[0072] also, Figure 5 2 is a cross-sectional view of a storage container 50B of an isotropic pressurizing device according to a second variant embodiment of the present invention. An opening and closing cover 51 (opening and closing member) that can open and close the central portion of the storage container body 501 is provided in the storage container 50B. Since the opening and closing cover 51 can seal and open the storage space S2, if the opening and closing cover 51 closes the storage container body 501, the flow of the pressure medium between the processing space S1 and the storage space S2 through the peripheral portion of the opening and closing cover 51 does not occur. In addition, a first flow path L1, a second flow path L2, a first check valve 503 and a second check valve 504 are provided at the axial end of the storage container body 501. In this structure, the isotropic pressurization treatment can also be performed on the processed object W while maintaining the heat preservation of the storage space S2 of the storage container 50.

[0073] The present invention provides an isotropic pressurizing device, which uses a pressure medium to perform isotropic pressurizing treatment on a processed object. The isotropic pressurizing device includes: a pressure vessel, which forms a processing space that can receive the pressure medium; and a receiving container, which is arranged in the processing space of the pressure vessel and forms a receiving space that can receive the processed object, wherein the receiving container has: a first flow path, which connects the receiving space and the processing space to each other; a second flow path, which is independently provided from the first flow path and connects the receiving space and the processing space to each other; a first check valve, which is arranged in the first flow path, and allows the pressure medium in the first flow path to flow from the receiving space to the processing space when the pressure in the processing space is higher than the pressure in the receiving space. and a second check valve, which is arranged in the second flow path and, when the pressure of the receiving space is higher than the pressure of the processing space, allows the flow of the pressure medium in the second flow path from the processing space to the receiving space while preventing the flow of the pressure medium in the second flow path from the processing space to the receiving space, and, when the pressure of the processing space is higher than the pressure of the receiving space, prevents the flow of the pressure medium in the second flow path from the processing space to the receiving space, and, when the pressure of the processing space is higher than the pressure of the receiving space, prevents the flow of the pressure medium in the second flow path between the processing space and the receiving space, and seals the receiving space.

[0074] According to this structure, the object to be processed is stored in the storage space of the storage container, and the storage container is arranged in the processing space of the pressure container, and the pressure medium is supplied to the processing space, thereby the object to be processed can be subjected to isotropic pressure treatment. In particular, the storage container is provided with a first flow path and a second flow path, and each flow path is provided with a first check valve and a second check valve. Therefore, if a pressure medium formed by, for example, hot water is supplied to the storage space together with the object to be processed in advance, and a pressure medium formed by water with a temperature lower than the temperature of the hot water is supplied to the processing space of the pressure container and pressurized, then through the action of the first check valve, the low-temperature pressure medium flows from the processing space into the storage space, and the object to be processed is subjected to isotropic pressure treatment. At this time, since the pressure medium formed by hot water is suppressed from flowing out of the storage space to the processing space through the action of the second check valve, the object to be processed can be subjected to pressure treatment while the temperature in the storage space is kept close to the temperature of the hot water. As a result, the object to be processed can be subjected to pressure treatment and heating treatment in parallel. In addition, it is not necessary to fill the processing space of the pressure vessel with a pressure medium formed by hot water in order to perform a heat treatment on the processed object, so the necessity of using a material with high heat resistance for the pressure vessel is reduced. Moreover, if the pressure medium is discharged from the processing space after the pressure treatment is completed, the second check valve allows the pressure medium to flow out from the receiving space to the processing space based on the pressure difference between the processing space and the receiving space. Therefore, the situation in which the receiving container is damaged due to the pressure difference between the processing space and the receiving space is suppressed.

[0075] In the above structure, preferably, the storage container is formed of a material having a lower thermal conductivity than that of the pressure container.

[0076] According to this configuration, since the heat insulation performance of the storage container is set higher than the heat insulation performance of the pressure container, the heat insulation performance of the storage space during the pressurization process can be improved.

[0077] In the structure described above, the storage container preferably comprises: a storage container body, which has a cylindrical inner circumferential surface defining the storage space and is formed with at least one opening portion allowing the processed object to pass through so as to arrange the processed object in the storage space; and at least one opening and closing component installed on the storage container body in a manner capable of opening and closing the at least one opening portion, wherein the first flow path and the second flow path are respectively arranged on the at least one opening and closing component, and the first check valve and the second check valve are respectively installed on the at least one opening and closing component corresponding to the first flow path and the second flow path.

[0078] According to this structure, the processed object can be easily put into the storage space through the opening. In addition, the opening and closing member has the first flow path, the second flow path, the first check valve and the second check valve, so that the maintenance convenience of the storage container can be improved.

[0079] In the structure, preferably: the at least one opening portion of the storage container body is formed by opening at least one of the two axial ends of the storage container body, and the at least one opening and closing member is installed on the at least one end of the storage container body in a manner that can open and close the at least one opening portion.

[0080] According to this structure, since the opening is formed at the axial end of the storage container body, the rigidity of the storage container body can be maintained higher than that of the case where the opening is formed at the axial center of the storage container body. In addition, the processed object and the pressure medium can be easily put into the storage space through the axial end of the storage container body.

[0081] The above structure preferably further includes: a pressure medium supply mechanism for supplying a pressure medium to the processing space of the pressure container; and a pressurizing mechanism for pressurizing the pressure medium supplied to the processing space.

[0082] According to this configuration, the object to be processed can be subjected to isotropic pressurization processing in a stable manner.

[0083] In addition, the present invention provides a storage container for an isotropic pressurizing device, which is a pressure container that can be detachably installed in the isotropic pressurizing device, wherein the isotropic pressurizing device uses a pressure medium to perform isotropic pressure treatment on the treated object, and the pressure container includes a cylindrical inner circumferential surface, and a processing space that can accommodate the treated object is formed inside. The storage container for the isotropic pressurizing device includes: a storage space; a first flow path that connects the storage space and the processing space to each other; a second flow path that is independently provided from the first flow path and connects the storage space and the processing space to each other; a first check valve that is arranged in the first flow path, and allows the pressure medium in the first flow path to flow from the processing space to the storage space when the pressure in the processing space is higher than the pressure in the storage space, while preventing the pressure medium in the first flow path from flowing into the processing space, and prevents the pressure medium from flowing into the processing space when the pressure in the processing space is lower than the pressure in the storage space. The first flow path allows the flow of pressure medium between the processing space and the receiving space and seals the receiving space; and a second check valve is arranged in the second flow path, and when the pressure of the receiving space is higher than the pressure of the processing space, the flow of pressure medium from the processing space to the receiving space in the second flow path is blocked, allowing the flow of pressure medium from the receiving space to the processing space in the second flow path while blocking the flow of pressure medium from the processing space to the receiving space, and when the pressure of the processing space is higher than the pressure of the receiving space, blocking the flow of pressure medium between the processing space and the receiving space in the second flow path and sealing the receiving space.

[0084] According to this structure, a first flow path and a second flow path are provided in a storage container for an isotropic pressurizing device, and a first check valve and a second check valve are arranged in each flow path. Therefore, if a pressure medium formed by, for example, hot water is supplied to the storage space together with the object to be processed in advance, and a pressure medium formed by water having a temperature lower than that of the hot water is supplied to the processing space of the pressure container and pressurized, the low-temperature pressure medium flows from the processing space into the storage space through the action of the first check valve, and the object to be processed is isotropically pressurized. At this time, since the pressure medium formed by hot water is suppressed from flowing out of the storage space into the processing space through the action of the second check valve, the object to be processed can be pressurized while keeping the temperature in the storage space close to the temperature of the hot water. As a result, the object to be processed can be pressurized and heated in parallel.

[0085] The present invention provides an isotropic pressure treatment method, which uses a pressure medium to perform isotropic pressure treatment on a treated object, and the isotropic pressure treatment method includes the following steps: a preparation step, respectively preparing a pressure container and a receiving container, wherein a processing space that can receive the pressure medium is formed in the pressure container, and a receiving space that can receive the treated object is formed in the receiving container, and the receiving container includes at least one flow path that connects the receiving space with the outside of the receiving container; a treated object receiving step, wherein the treated object is received in the receiving space of the receiving container, and a first pressure medium is filled into the receiving space; a receiving container configuration step, wherein the receiving container including the treated object is configured in the processing space of the pressure container; and a pressure treatment step, wherein a second pressure medium whose temperature is set to be lower than that of the first pressure medium is supplied to the processing space of the pressure container and the second pressure medium is pressurized, and while allowing the second pressure medium to flow from the processing space into the receiving space through the at least one flow path, the treated object in the receiving container is subjected to isotropic pressure treatment.

[0086] According to the present method, if a first pressure medium formed of, for example, hot water is supplied to the receiving space together with the treated object in the treated object receiving step, and a second pressure medium formed of water having a temperature lower than that of the hot water is supplied to the processing space of the pressure vessel and pressurized in the pressurization step, the second pressure medium flows from the processing space into the receiving space through at least one flow path, and the treated object is isotropically pressurized. Therefore, the treated object can be pressurized while the temperature in the receiving space is kept close to the temperature of the hot water. As a result, the treated object can be pressurized and heated in parallel.

[0087] In the method described, preferably: the preparation step includes the step of preparing a container in which the at least one flow path is formed by a first flow path and a second flow path independent of each other, and has a first check valve and a second check valve as the receiving container, wherein the first check valve is arranged in the first flow path, and when the pressure of the processing space is higher than the pressure of the receiving space, the flow of the pressure medium in the first flow path from the processing space to the receiving space is allowed while the flow of the pressure medium in the first flow path from the receiving space to the processing space is blocked, and when the pressure of the processing space is lower than the pressure of the receiving space, the flow of the pressure medium between the processing space and the receiving space in the first flow path is blocked and the receiving space is sealed, and the second check valve is arranged in the second flow path, and when the pressure of the receiving space is higher than the pressure of the processing space, the flow of the pressure medium in the second flow path from the processing space to the receiving space is allowed while the flow of the pressure medium in the second flow path from the processing space to the receiving space is blocked. The pressure medium in the second flow path flows from the containing space to the processing space, and when the pressure in the processing space is higher than the pressure in the containing space, the flow of the pressure medium between the processing space and the containing space in the second flow path is blocked and the containing space is sealed. The pressurization treatment step includes the following steps: when the inflow channel of the second pressure medium from the processing space to the containing space during pressurization is restricted to the first flow path opened by the first check valve, the processed object in the containing container is subjected to isotropic pressurization treatment. The isotropic pressurization treatment method also includes a decompression treatment step. After the pressurization treatment step, the second pressure medium is discharged from the processing space, and the second flow path is opened by the second check valve due to the pressure difference generated between the processing space and the containing space, so that the pressure inside the pressure container is decompressed while allowing the pressure medium containing the first pressure medium and the second pressure medium to be discharged from the containing space to the processing space.

[0088] According to the present method, the second pressure medium flows from the processing space into the receiving space by the action of the first check valve, and the processed object is isotropically pressurized. At this time, since the first pressure medium is suppressed from flowing out of the receiving space into the processing space by the action of the second check valve, the processed object can be pressurized while the temperature in the receiving space is stably maintained close to the temperature of the first pressure medium. In addition, if the pressure medium is discharged from the processing space after the pressurized treatment is completed, the second check valve allows the pressure medium to flow out of the receiving space into the processing space based on the pressure difference between the processing space and the receiving space. Therefore, the situation in which the receiving container is damaged due to the pressure difference between the processing space and the receiving space is suppressed.

[0089] In the method described, preferably: the preparation step includes the step of preparing a container having a storage container body and at least one opening and closing member as the storage container, wherein the storage container body has a cylindrical inner circumferential surface defining the storage space, and is formed with at least one opening portion allowing the processed object to pass through, so as to arrange the processed object in the storage space, and the at least one opening and closing member is installed on the storage container body in a manner that the at least one opening portion can be opened and closed, and the at least one opening and closing member is respectively provided with the first flow path, the second flow path, the first check valve and the second check valve, and the processed object storage step includes the steps of storing the processed object in the storage space through the at least one opening portion, filling the storage space with the first pressure medium, and closing the at least one opening portion with the at least one opening and closing member.

[0090] According to this method, the processed object can be easily put into the storage space through the opening. In addition, the opening and closing member has the first flow path, the second flow path, the first check valve and the second check valve, so that the maintenance convenience of the storage container can be improved.

[0091] In the method described, preferably: the preparation step includes the step of preparing a container formed of a material with a lower thermal conductivity than that of the pressure vessel as the receiving container, and the pressurization treatment step includes the following steps: during the pressurization process, the inflow channel of the second pressure medium from the processing space to the receiving space is restricted to the at least one flow path, and the first pressure medium is inhibited from flowing out of the receiving space to the processing space, and the receiving space is insulated by using the receiving container.

[0092] According to this method, the thermal insulation performance of the storage container is set higher than the thermal insulation performance of the pressure container, and the outflow of the first pressure medium from the storage space to the processing space is suppressed, so the thermal insulation performance of the pressurized storage space can be improved.
