[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a high-pressure processing apparatus, which is used for high-pressure processing of food, molding of resin, pressure crystallization, supercritical extraction and the like.

[0002]

[Prior art]

 The high-pressure processing equipment used for high-pressure processing of food and molding of resin, etc. processes pressure by superimposing temperature, and its temperature range is about 300 to -20 ° C. As a means for raising or lowering the temperature, there is one that employs an external heating / cooling method.

That is, as shown in FIG. 5, the upper and lower lids 4 and 5 are fitted into the upper and lower openings of the pressure vessel 3 in which the inner cylinder 1 and the outer cylinder 2 are shrink-fitted, and the like. In addition to freely opening and closing 6, a container frame 8 having a jacket 7 is provided on the outer peripheral surface of the pressure container 3 to form a heat / refrigerant recirculation region 9. The object to be treated 6A in the processing chamber 6 is surrounded by a pressure medium such as water, propylene glycol, silicone oil, etc., and is heated or cooled by a heating unit or cooling unit (not shown) in the heat / refrigerant recirculation region 9. By circulating the generated heat / refrigerant, heating / cooling is performed from the outer peripheral surface of the pressure vessel 3 via the vessel 3.

In FIG. 5, 10 is a heat insulating cylinder, 11 is a sealing means such as an O-ring, which seals against the outer peripheral surface of the pressure vessel 3, and 12 is a press frame for bearing the axial force of the vessel. Yes, it can be freely attached to and detached from the upper and lower lids 4, 5.

[0005]

[Problems to be solved by the device]

 The conventional technique shown in FIG. 5 has the following problems because the jacket 7 and the container frame 8 are integrally structured. When the pressure medium in the processing chamber 6 is heated / cooled, the jacket 7 is in contact with the heat / refrigerant circulating in the heat / refrigerant recirculation region 9, so the jacket 7 and the container frame 8 are also heated / cooled. This heat energy is wasted.

Therefore, even if the weight is reduced or the heat radiation area is reduced, the jacket 7 and the container frame 8 are structural members that support the pressure container 3 and cannot be performed. Also, the wasted thermal energy was conducted through the container frame 8 and the efficiency was very poor.

On the other hand, during cooling, a loss of cooling energy (solidification heat) occurs between the heat insulating material 10 and the container frame 8 because the moisture in the air solidifies. Further, since the jacket 7 is exposed to the outside air though it is through the heat insulating material 10, the moisture in the air is solidified between the jacket 7 and the heat insulating material 10 one after another, which causes a large cooling energy loss.

Further, the sealing means 11 on the upper side cannot be replaced unless the pressure vessel 3 is completely withdrawn when replacing it. Therefore, it is an object of the present invention to provide a high-pressure processing apparatus that can suppress heat energy loss due to conduction and cooling energy loss due to solidification heat and can easily replace the sealing means.

[0009]

[Means for Solving the Problems]

 According to the present invention, a jacket 7 is provided on the outer peripheral surface of a pressure vessel 3 having a processing chamber 6 which can be closed and opened freely, to form a heat / refrigerant recirculation region 9, and the jacket 7 is inserted through a heat insulating cylinder 10 to form a container frame In order to achieve the above-mentioned object, in the high-pressure processing apparatus for heating and cooling the object 6A to be processed in the processing chamber 6 from the outer peripheral surface of the pressure container 3 through the container 3 in preparation for Are taking technical measures.

That is, according to the present invention, the jacket 7 is integrated with the upper and lower annular bodies 7A and 7B having the sealing means 11 for the outer peripheral surface of the pressure vessel 3 and the upper and lower annular bodies 7A and 7B. The upper and lower annular bodies 7A and 7B of the jacket 7 are in contact with the container frame 8, and the cylindrical body 7C is not in contact with the heat insulating cylinder 10 with a clearance 10A. The jacket 7 is provided so that it can be inserted into and removed from the pressure vessel 3 and the vessel frame 8 in the vessel axial direction.

[0011]

[Action]

 By circulating the heat / refrigerant in the heat / refrigerant recirculation region 9, the pressure medium in the processing chamber 6 is heated / cooled through the container 3 to process the object 6A to be processed under high pressure. The thermal energy in the recirculation region 9 is that the upper and lower annular bodies 7A and 7B of the jacket 7 are in contact with the container frame 8 and the cylindrical body 7C has a clearance of 10A and is not in contact. Emissions are suppressed.

In order to replace the sealing means 11, it suffices to pull out the jacket 7 to the extent that the sealing means 11 is exposed in the axial direction of the container.

[0013]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. It should be noted that the same configurations as the conventional configuration are denoted by common reference numerals, and the improvements will be described in detail below. 1 to 3, the jacket 7 is divided (separated) from the container frame 8, and the jacket 7 includes upper and lower annular bodies 7A and 7B having sealing means 11 for the outer peripheral surface of the pressure container 3, The upper and lower annular bodies 7A and 7B are integrally formed with a cylindrical body 7C, the upper and lower annular bodies 7A and 7B contact the container frame 8, and the cylindrical body 7C is spaced from the heat insulating cylinder 10. The jacket 7 is provided in a non-contact manner with 10A, and the jacket 7 is provided so as to be inserted into and removed from the pressure vessel 3 and the vessel frame 8 in the vessel axial direction as shown in FIG.

The sealing means 11 comprises an O-ring 11A and a backup ring 11B, and the lower annular body 7B is fitted and supported by a step portion 8A formed in the container frame 8. Therefore, in the jacket 7 according to the embodiment of the present invention, the upper and lower annular bodies 7A and 7B only contact the container frame 8, and the contact area is very small, so that the thermal energy loss due to conduction is reduced. become.

Further, since the jacket 7 is located in a semi-sealed place by the container frame 8, the phenomenon in which moisture in the air of the outside air is solidified one after another during cooling is reduced, and the cooling energy due to the heat of solidification is reduced. Loss is suppressed. Furthermore, when replacing the sealing means 11, the jacket 7 can be replaced by pulling it out until the sealing means 11 is positioned above the upper end surface of the pressure vessel 3 as shown in FIG.

Further, the jacket 7 is sufficient as long as it can withstand the circulation pressure of heat and refrigerant, for example, 10 kgf / cm ² or less, so it can be made lighter, which can suppress energy loss, and the clearance 8A can be assembled and disassembled. The heat insulating function can be achieved while facilitating the heat treatment. In the embodiment described in detail above, the heat insulating material 10 may be provided not on the inner side of the container frame 8 but on the outer circumference of the cylindrical body 7C of the jacket 7, or inside the pressure container frame 8. It can be provided both on the outside of the jacket 7.

[0017]

[Effect of device]

 As described above in detail, according to the present invention, the contact area between the jacket and the container frame is small, so that the heat energy loss due to conduction can be reduced, and the jacket is semi-sealed by the container frame, so that the cooling The cooling energy loss due to the heat of solidification at that time can also be suppressed.

There is also an advantage that the sealing means can be replaced easily and quickly.
