The CIP apparatus 1 applies isostatic pressing treatment to an object to be treated using a pressure medium.

[0012] Hereinafter, embodiments of the present disclosure are described with reference to drawings. In the following description, an object to be treated which is an object to which treatment is applied is food. However, an object to be treated may be other than food, and an inorganic substance (inorganic powder) such as metal powder or ceramic powder may be an object to be treated.

[0013] The CIP apparatus 1 according to an embodiment of the present disclosure includes a pressure vessel 2, a basket 23 (storage vessel), and a pressing apparatus body 100. The pressing apparatus body 100 includes: a press frame 10; a second lid cylinder 12; rails 13; a water supply/discharge unit 31 (pressure medium supply mechanism); a pump unit 32 (pressing mechanism); a preheating heater 33; a controller 35, a movement mechanism 60; a first lid cylinder 61, and a cart 65.

[0014] An object to be treated is stored in the pressure vessel 2, and the pressure vessel 2 applies isostatic pressing treatment to the object to be treated. The pressure vessel 2 includes a vessel body 20, a first lid 21 (lid), and a second lid 22 (lid). The pressure vessel 2 is made of a metal material such as stainless steel.

[0015] The vessel body 20 includes an inner peripheral surface having a cylindrical shape which is formed around a center axis extending along a horizontal direction. In the vessel body 20, a treatment space S defined by the inner peripheral surface is formed. Both end portions of the inner peripheral surface in an axial direction are opened.

[0016] The first lid 21 and the second lid 22 are respectively mounted on both end portions of the vessel body 20 in the axial direction to seal the treatment space S.

[0017] The basket 23 stores an object to be treated, and is disposed in the treatment space S of the pressure vessel 2. In the present embodiment, the basket 23 is formed of a resin material having a cylindrical shape. The basket 23 has a semi-sealed structure for allowing pressing treatment of an object to be treated stored in the basket 23. Water can be stored in the basket 23. The basket 23 has heat insulation performance.

[0018] The first lid 21 and the basket 23 form a lid unit 2S (a storage unit for an isostatic pressing apparatus) in the present embodiment. The lid unit 2S is integrally mounted on the vessel body 20.

[0019] The press frame 10 has a function of supporting an axial force acting on both end lids of the pressure vessel 2. The press frame 10 has a frame structure, and when the pressure vessel 2 is disposed at a pressing position P in the frame, isostatic pressing treatment is applied to an object to be treated in the pressure vessel 2.

[0020] The second lid cylinder 12 is a hydraulic cylinder supported by a right frame 1OB of the press frame 10 in an extensible and retractable manner. The second lid cylinder 12 has a function of mounting and separating the second lid 22 of the pressure vessel 2 disposed at the pressing position P to and from the vessel body 20 by way of a pressure receiving plate.

[0021] The rails 13 guide the pressure vessel 2 such that the pressure vessel 2 is movable between the pressing position P and a standby position Q. As illustrated in FIG. 2, the standby position Q is the position spaced apart rearward from the pressing position P. In the pressure vessel 2, the vessel body 20 and the first lid 21 move between the pressing position P and the standby position Q, and the second lid 22 is always disposed at the pressing position P. That is, the second lid 22 is fixed to the second lid cylinder 12 in advance.

[0022] The water supply/discharge unit 31 includes a tank 31A, and supplies a pressure medium to the treatment space S of the pressure vessel 2. In the present embodiment, fresh water or hot water is used as the pressure medium.

[0023] The pump unit 32 pressurizes the pressure medium sealed in the treatment space S. In the present embodiment, simultaneously with supplying of the pressure medium to the treatment space S, the pressure medium is pressurized by the pump unit 32.

[0024] The preheating heater 33 heats (adjusts a temperature of) the lid unit 2S before the pressing treatment is performed when necessary.

[0025] The movement mechanism 60 includes a hydraulic cylinder (not illustrated), and moves the vessel body 20 on which the lid unit 2S is mounted between the pressing position P and the standby position Q.

[0026] The first lid cylinder 61 has both a function of mounting the lid unit 2S on the vessel body and a function of separating the lid unit 2S from the vessel body 20 at the standby position Q. The first lid cylinder 61 includes a cylinder body 62 and a rod portion 63. The cylinder body 62 is fixed to an upper surface portion of the vessel body 20. Along with supply of hydraulic oil from a hydraulic source (not illustrated) to the first lid cylinder 61 and discharge of the hydraulic oil from the first lid cylinder 61, the rod portion 63 extends and retracts with respect to the cylinder body 62. A proximal end portion of a connecting wire 64 is connected to a distal end portion of the rod portion 63, and a distal end portion of the connecting wire 64 is locked to a locking portion 21S of thefirstlid21. When the rod portion 63 retracts so as to enter the cylinder body 62 from a state illustrated in FIG. 1, the lid unit 2S is towed by the first lid cylinder 61 and mounted on the vessel body 20. On the other hand, when the rod portion 63 extends from a state where the lid unit 2S is mounted on the vessel body 20 with respect to the cylinder body 62, the lid unit 2S is separated from the vessel body 20. The cart 65 supports the basket 23 of the lid unit 2S from below. Immediately before the lid unit 2S is mounted on the vessel body 20, an operator separates the cart from the vessel body 20. In order to smoothly mount the lid unit 2S on the vessel body 20, rollers (not illustrated) may be disposed on a lower end of a distal end portion of the basket 23. The rollers roll on the inner peripheral surface of the vessel body 20 so as to assist mounting of the lid unit 2S.

[0027] The controller 35 controls operations of the first lid cylinder 61, the second lid cylinder 12, the water supply/discharge unit 31, the pump unit 32, the preheating heater 33, and the movement mechanism 60. The controller 35 includes an operation panel (not illustrated).

[0028] With reference to FIG. 3 and FIG. 4, the first lid 21 includes: a first lid body 210; a drain valve 211; a sealing portion 212; a spring 213; and a pair of connecting bolts 214 (connecting portions).

[0029] The first lid body 210 is a body portion of the first lid 21. The first lid body 210 includes a first body portion 210A and a second body portion 21OB, and has a two-stage cylindrical shape.

[0030] The drain valve 211 is formed in the first lid body 210 below a center axis of the first lid body 210 along an axial direction of the first lid body 210. The drain valve 211 allows the outside of the first lid body 210 and the treatment space S to communicate with each other. Thedrain valve 211 may be formed on the second lid 22.

[0031] The sealing portion 212 is mounted on an outer side surface of the first lid body 210 so as to seal the drain valve 211. The spring 213 biases the sealing portion 212 outward in the axial direction. When the sealing portion 212 is separated from the drain valve 211 by a biasing force of the spring 213, a pressure medium (water) is discharged from the basket 23 (treatment space S) through the drain valve 211.

[0032] The pair of connecting bolts 214 is fixed to a distal end portion of the second body portion 210B. The connecting bolts 214 are inserted into hole portions 233 formed in the basket 23. The connection between the first lid 21 and the basket 23 is not limited to the connection using the bolts.

[0033] The second lid 22 includes: a second lid body 220; and a water supply/discharge path 221 (FIG. 3). High-pressure pipes and the like are provided to the second lid 22.

[0034] The second lid body 220 is a body portion of the second lid 22, and has the same shape as the first lid body 210.

[0035] The water supply/discharge path 221 allows the outside of the second lid 22 and the treatment space S to communicate with each other. The water supply/discharge path 221 communicates with the water supply/discharge unit 31 and the pump unit 32 through a flow path (not illustrated) formed in the second lid cylinder 12 and the right frame 10B.

[0036] The basket 23 includes: a basket body 230; a thermocouple storing portion 231 (sensor storing portion); an opening and closing portion 232; and a pair of hole portions 233 (portions to be connected).

[0037] The basket body 230 is made of a resin material and has a cylindrical shape. An object to be treated such as food is stored in the basket body 230. In the basket body 230, check valves in both directions may be disposed. Such check valves enable the flow of a pressure medium between the treatment space S and the inside of the basket body 230.

[0038] The thermocouple storing portion 231 receives a thermocouple 50 described later when the first lid 21 and the basket 23 are connected with each other. The thermocouple storing portion 231 has a circular pipe shape, and both end portions of the thermocouple storing portion 231 are opened. A proximal end portion of the thermocouple storing portion 231 is fixed to a side surface of the basket body 230 on a first lid 21 side. A distal end portion of the thermocouple storing portion 231 is located in the basket body 230.

[0039] The opening and closing portion 232 is disposed on an upper surface portion of the basket body 230 in an openable/closable manner. By opening and closing the opening and closing portion 232, an operator can put an object to be treated into the basket body 230 and can take out the object to be treated from the basket body 230. A plurality of opening portions (not illustrated) may be formed in the opening and closing portion 232, and a pressure medium is allowed to flow between the inside of the basket body 230 and the treatment space S through the opening portions.

[0040] The pair of hole portions 233 is opened on a side surface of the basket body 230 on a first lid 21 side. The hole portions 233 receive the connecting bolts 214 described above.

[0041] As illustrated in FIG. 4, in the present embodiment, the pair of connecting bolts 214 is inserted into the pair of hole portions 233 and, thereafter, nuts (not illustrated) are fastened to the distal end portions of the connecting bolts 214 so that the connecting bolts 214 and the hole portions 233 are connected to each other. As a result, the first lid 21 and the basket 23 can be integrally mounted on the vessel body 20 of the pressure vessel 2. Therefore, in the pressure vessel 2, the first lid 21 is connected to the basket 23 in the treatment space S. In FIG. 2, a plurality of lid units 2S (first lids 21, baskets 23) are disposed at the standby position Q.

[0042] Further, the CIP apparatus 1 includes the thermocouple 50 (a temperature sensor). The thermocouple 50 is supported by the first lid 21. The thermocouple 50 has a detection unit 50S which is disposed in the treatment space S when the first lid 21 is mounted on the vessel body 20 of the pressure vessel 2. The thermocouple 50 outputs an output signal corresponding to a temperature detected by the detection unit 50S.

[0043] The thermocouple 50 is inserted into the thermocouple storing portion 231 (sensor storing portion) of the basket 23. As a result, when the first lid 21 is mounted on the vessel body 20 of the pressure vessel 2 together with the basket 23, the detection unit 50S of the thermocouple 50 is disposed in the basket 23 in the treatment space S.

[0044] With reference to FIG. 4, assuming a length of the treatment space S in the pressure vessel 2 in the axial direction as L, and a distance in the axial direction from an end portion of the treatment space S on the first lid 21 side to the detection unit 50S of the thermocouple 50 as M, a relationship of 0 < M/L < 1 is satisfied. In the present embodiment, the distance M is also equal to a length of the thermocouple storing portion 231.

[0045] When applying isostatic pressing treatment to an object to be treated, first, the vessel body , the first lid 21, the basket 23, the thermocouple 50, and the pressing apparatus body 100 are prepared (preparation step). As described above, the lid unit 2S is formed by connecting (fixing) the first lid 21 and the basket 23 to each other in advance (storage vessel fixing step). An operator inserts an object to be treated such as food into the basket 23 of the lid unit 2S (storing step). The controller 35 adjusts a temperature of the lid unit 2S at the standby position Q by controlling the preheating heater 33 (temperature adjusting step). As a result, a temperature of the object to be treated stored in the basket 23 can be maintained. In another embodiment, the preheating heater 33 may not be provided. Then, in response to a command operation by an operator, the controller drives the first lid cylinder 61 so that the lid unit 2S is mounted on the vessel body 20. As a result, the pressure vessel 2 (excluding the second lid 22) is assembled (pressure vessel assembling step).

[0046] Next, the controller 35 drives the movement mechanism 60 so as to set the vessel body 20 including the lid unit 2S at the pressing position P in the press frame 10 (pressing treatment step). At the pressing position P on the rails 13, the second lid 22 is disposed in a state where the second lid 22 faces the vessel body 20.

[0047] When the vessel body 20 is disposed at the pressing position P, the second lid cylinder 12 extends, and the second lid 22 is mounted on the vessel body 20 by way of the pressure receiving plate (not illustrated). As a result, the treatment space S is brought into a sealed state.

[0048] Next, the controller 35 controls the water supply/discharge unit 31 so as to supply hot water (pressure medium) from the water supply/discharge unit 31 into the treatment space S through the right frame 1OB and the second lid 22. Hot water is supplied to the treatment space S until the treatment space S is filled with hot water. Next, the controller 35 controls the pump unit 32 so as to pressurize hot water in the treatment space S (isostatic pressing treatment, pressing treatment step). At this stage of the operation, since the volume of hot water in the treatment space S is reduced by pressing, water at a room temperature is additionally replenished. By continuously performing the isostatic pressing treatment for a predetermined time, sterilization or the like is applied to an object to be treated in the basket 23.

[0049] In the present embodiment, as described above, hot water is supplied to the pressure vessel 2 before pressing, and water at a room temperature is replenished during pressing. This is because, in view of characteristics of a seal member (not illustrated) and the like in the pressure vessel 2, it is not preferable to replenish pressurized high-temperature water (hot water) into the pressure vessel 2. In this case, a temperature in the pressure vessel 2 during pressing is lower than the temperature before the pressing. Therefore, it is important to detect a temperature in the treatment space S by the thermocouple 50 during pressing.

[0050] When the isostatic pressing treatment is finished, the pressure reducing treatment is applied to the treatment space S. At this stage of the operation, hot water is discharged from the drain valve 211 of the first lid 21. Hot water is also discharged through water supply/discharge path 221 of the second lid 22. The second lid cylinder 12 separates the second lid 22 from the vessel body by way of the pressure receiving plate. Then, the vessel body 20 including the lid unit 2S is again moved to the standby position Q by the movement mechanism 60 (FIG. 1). Then, the lid unit 2S is taken out from the vessel body 20 by the first lid cylinder 61, and an object to be treated to which pressing treatment has been applied is taken out from the basket 23 of the lid unit 2S (pressure vessel disassembling step).

[0051] As described above, before the lid unit 2S is mounted on the vessel body 20, a temperature of an object to be treated in the basket 23 may be adjusted by the preheating heater 33 (temperature adjusting step). At this stage of the operation, a temperature of an object to be treated which is being subjected to the temperature adjusting step may be monitored by the thermocouple 50 (adjusted temperature monitoring step).

[0052] As illustrated in FIG. 2, a plurality of lid units 2S may be prepared for one vessel body 20. That is, one lid unit 2S which includes one basket 23 and one first lid 21, and the other lid unit 2S which includes the other basket 23 and the other first lid 21 are prepared. The above-mentioned pressing treatment step for the pressure vessel 2 which includes the one lid unit 2S, and the temperature adjusting step for the other basket 23 or for the other lid unit 2S which includes the other basket 23 may be performed in parallel.

[0053] As described above, in the present embodiment, a temperature of an object to be treated which is being subjected to the pressing treatment can be monitored by the thermocouple 50. For this reason, even when an object to be treated is likely to be easily affected by a temperature as in the case of food, the pressing treatment can be stably performed. In addition, since the detection unit 50S of the thermocouple 50 is disposed in the treatment space S, a temperature of an object to be treated can be accurately detected. In addition, since the thermocouple 50 is supported by the first lid 21, electric wiring of the thermocouple 50 can be pulled out to the outside of the pressure vessel 2 through the first lid 21. With such a configuration, the routing of electric wiring on the vessel body 20 can be reduced.

[0054] In the present embodiment, when the first lid 21 is mounted on the vessel body 20 of the pressure vessel 2, the detection unit 50S is disposed in the basket 23. Therefore, since the detection unit 50S of the thermocouple 50 is disposed in the treatment space S, particularly in the basket 23, the temperature of the object to be treated can be detected more accurately.

[0055] Further, in the present embodiment, the basket 23 has the thermocouple storing portion 231 which receives the thermocouple 50 when the first lid 21 and the basket 23 are connected to each other. In this manner, since the thermocouple 50 is stored in the thermocouple storing portion 231 in the basket 23, it is possible to preventthe thermocouple 50 from being damaged by interference with an object to be treated.

[0056] In the present embodiment, the first lid 21 and the basket 23 are integrally mounted on the vessel body 20. Accordingly, the detection unit 50S of the thermocouple 50 can be easily disposed in the treatment space S and in the basket 23. In addition, a temperature of an object to be treated in the basket 23 can be monitored before the lid unit 2S is mounted on the vessel body 20. In addition, the relative positions of the first lid 21, the basket 23, and the thermocouple 50 are fixed and hence, it is unnecessary to mount or remove the thermocouple 50 for each treatment. Accordingly, it is possible to prevent the thermocouple 50 from being damaged, and the position of the thermocouple 50 can be stably maintained.

[0057] Furthermore, in the present embodiment, as described above, the relationship of 0 < M/L < 1 is satisfied. Therefore, the detection unit 50S of the thermocouple 50 is disposed in the treatment space S and hence, a temperature of an object to be treated can be detected more accurately.

[0058] In addition, in the present embodiment, the thermocouple 50 is used as a temperature sensor that detects a temperature in the treatment space S. Therefore, a temperature of an object to be treated can be easily detected by the simple thermocouple 50.

[0059] In the present embodiment, the controller 35 can measure a temperature of an object to be treated in the basket 23 by receiving an output signal from the thermocouple 50 in the steps from the object-to-be-treated storing step, through the pressing treatment step, to the pressure vessel disassembling step. In general, when hot water is used in the CIP apparatus 1, first, a temperature of the basket 23 increases in a preheating stage of the basket 23 by the preheating heater 33. Then, after hot water is supplied to the pressure vessel 2, a temperature in the pressure vessel 2 decreases at the pressing stage. On the other hand, when cold water is used in the CIP apparatus 1, the pressure vessel 2 is cooled in advance at the standby position Q (temperature adjustment). Then, after cold water is supplied to the pressure vessel 2, a temperature in the pressure vessel 2 increases at a pressing stage. 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. Also in the temperature adjusting step performed prior to the pressing treatment step, the controller 35 receives an output signal of the thermocouple 50. Accordingly, a temperature of an object to be treated in the basket 23 before the pressing treatment is applied to the object to be treated can be measured.

[0060] As described above, in the present embodiment, the first lid 21 and the basket 23 are connected to each other in advance thus forming the lid unit 2S (storage unit for isostatic pressing treatment). The lid unit 2S is detachably mounted on the vessel body 20 in the CIP apparatus 1 (isostatic pressing apparatus) that applies isostatic pressing treatment to an object to be treated using a pressure medium. The vessel body 20 includes the inner peripheral surface having a cylindrical shape which is formed around the center axis extending along the horizontal direction, and the treatment space S capable of storing the object to be treated is formed in the vessel body 20. The lid unit 2S includes: the first lid 21 that is detachably mounted on one end portion of the inner peripheral surface of the vessel body 20 in the axial direction, and seals the treatment space S; the basket 23 that stores the object to be treated in the basket 23, is fixed to the first lid 21 so as to be detachably mounted on the vessel body 20 integrally with the first lid 21, and is disposed in the treatment space S of the vessel body 20; and a thermocouple 50 that is supported by the first lid 21, has the detection unit 50S disposed in the treatment space S, and outputs an output signal corresponding to a temperature detected by the detection unit 50S.

[0061] By allowing the lid unit 2S to have such a configuration, the detection unit 50S of the thermocouple 50 and an object to be treated can be easily disposed in the treatment space S by mounting the lid unit 2S on the vessel body 20. As illustrated in FIG. 2, the plurality of lid units 2S are prepared in advance and are sequentially (alternately) conveyed with respect to the pressing position P. Accordingly, the pressing treatment applied to an object to be treated can be efficiently performed.

[0062] The isostatic pressing treatment method according to the present embodiment for applying isostatic pressing treatment to an object to be treated using a pressure medium includes the following steps. The isostatic pressing treatment method includes a preparation step, a storage vessel fixing step, an object-to-be-treated storing step, a pressure vessel assembling step, a pressing treatment step, and a pressure vessel disassembling step.

[0063] In the preparation step, the vessel body 20, the first lid 21, the basket 23, the thermocouple , and the pressing apparatus body 100 are prepared. The vessel body 20 includes the inner peripheral surface having a cylindrical shape formed around the center axis extending along the horizontal direction. The inner peripheral surface defines and forms the treatment space S in the vessel body 20. The end portions of the inner peripheral surface in the axial direction are opened. The first lid 21 is detachably mounted on the end portion of the vessel body 20 in the axial direction, and seals the treatment space S. The basket 23 can store an object to be treated. The thermocouple 50 has the detection unit 50S which can be disposed in the treatment space S, and outputs an output signal corresponding to a temperature detected by the detection unit 50S. The pressing apparatus body 100 supports at least the vessel body 20 and can perform isostatic pressing treatment.

[0064] In the storage vessel fixing step, the basket 23 is fixed to the first lid 21 in a state where the first lid 21 is separated from the vessel body 20.

[0065] In the object-to-be-treated storing step, the object to be treated is stored in the basket 23.

[0066] In the pressure vessel assembling step, the pressure vessel 2 (excluding the second lid 22) is assembled by integrally mounting the first lid 21 and the basket 23 on the vessel body 20 such that the basket 23 is disposed in the treatment space S.

[0067] In the pressing treatment step, the pressure vessel 2 is installed in the pressing apparatus body 100, and isostatic pressing treatment is applied to the object to be treated in the basket 23 by supplying a pressure medium to the treatment space S, and a temperature of the object to be treated which is being subjected to the isostatic pressing treatment is monitored by the thermocouple 50.

[0068] In the pressure vessel disassembling step, the pressure vessel 2 is disassembled by separating the pressure vessel 2 from the pressing apparatus body 100 and removing the first lid 21 and the basket 23 from the vessel body 20. In the preparation step, two or more pressure vessels 2 and two or more baskets 23 may be prepared.

[0069] According to the present method, a temperature of an object to be treated which is being subjected to the pressing treatment can be monitored by the thermocouple 50. For this reason, even when an object to be treated is likely to be easily affected by a temperature as in the case of food, the pressing treatment can be stably performed. In addition, since the thermocouple 50 is disposed in the basket 23 of the treatment space S, a temperature of an object to be treated can be accurately detected.

[0070] Further, in the present embodiment, the isostatic pressing treatment method includes, prior to the pressure vessel assembling step, mounting the thermocouple 50 on the first lid 21 such that the detection unit 50S of the thermocouple 50 is disposed in the basket 23.

[0071] According to the present method, the detection unit 50S of the thermocouple 50 can be easily disposed in the treatment space S and in the basket 23 by integrally mounting the first lid 21 and the basket 23 on the vessel body 20.

[0072] In the present embodiment, the isostatic pressing treatment method further includes: prior to the pressure vessel assembling step, the temperature adjusting step of performing a temperature adjusting process of adjusting a temperature of the object to be treated in the basket 23; and the adjusted temperature monitoring step of monitoring the temperature of the object to be treated which is being subjected to the temperature adjusting process by the thermocouple 50.

[0073] According to the present method, by adjusting a temperature of an object to be treated while monitoring the temperature prior to the pressing treatment, the pressing treatment can be promptly started.

[0074] In the present embodiment, the isostatic pressing treatment method further includes: preparing the first first basket 23 (one basket 23) and the first lid 21 (one first lid 21), and the second basket 23 (the other basket 23) and the second first lid 21 (the other first lid 21) in the preparation step; performing the pressing treatment step for the pressure vessel 2 including the first basket 23 and the first first lid 21 and the temperature adjusting step for the second basket 23 in parallel; and installing the pressure vessel 2 including the second basket 23 and the second first lid 21 which are already subjected to the temperature adjusting step on the pressing apparatus body 100 after separating the pressure vessel 2 which includes the first basket 23 and the first first lid 21 from the pressing apparatus body 100.

[0075] According to the present method, it is possible to efficiently apply the isostatic pressing treatment to objects to be treated stored in the plurality of baskets 23. In particular, preheating treatment can be applied to the second basket 23 during a period in which the pressing treatment is applied to the pressure vessel 2 including the first basket 23.

In addition, the thermocouple 50 may be supported by the second lid 22, or a sensor other than the thermocouple 50 may be used as the temperature sensor.

The sheath heater 51 is connected to a power supply (not illustrated) via the first lid 21.
