Description

Technical Field

[0001] This invention relates to the field of food processing, and more particularly to a high-capacity energy storage pressure tank device with a cooling system. Background Technology

[0002] High-pressure processing (HPP) involves applying pressure of 400–600 MPa to materials within a sealed, ultra-high-pressure container using water as the medium, or 100–1000 MPa using high-grade hydraulic oil. This kills almost all bacteria, molds, and yeasts present in the material. It is currently widely used in food processing and pharmaceutical industries.

[0003] HHP technology, as an emerging technology applied to food preservation, primarily works by damaging the cell membranes and walls of microorganisms, altering cell morphology, and affecting intracellular enzyme activity and the transport of nutrients and waste products, thereby killing spoilage and pathogenic bacteria in food. Simultaneously, HHP can effectively or partially inactivate endogenous enzymes in food. The main advantages of this technology are: firstly, as a physical method, it kills pathogenic and spoilage bacteria without heating or adding chemical preservatives, thus ensuring food safety and extending shelf life; secondly, as a non-thermal processing method, HHP does not involve drastic temperature changes during sterilization, does not break covalent bonds, has minimal impact on small molecules, and can better preserve the original color, aroma, flavor, function, and nutritional components of food.

[0004] In actual use, the use of ultra-high pressure extrusion will raise the temperature of the water. High temperature may cause protein denaturation in food. Therefore, how to solve this problem is a challenge we are currently facing. Summary of the Invention

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, known structures and processes are not described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles disclosed in this application.

[0019] Please see Figures 1-7This invention discloses a high-capacity energy storage pressure tank device with a cooling system, including a base, a sealing assembly 3, a cooling system 2, and a pressure tank 6. The sealing assembly is installed on the base and is adapted to the pressure tank 6. The pressure tank 6 has material inlets at both ends. The sealing assembly 3 includes a plug 31 and a driving structure. The cooling system 2 is disposed between the plug 31 and the driving structure and includes a liquid guide pipe 21, a temperature controller 22, and a liquid distributor 23. One end of the liquid guide pipe 21 is connected to an external device, and the other end is connected to the temperature controller 22. The temperature controller 22 is fitted to the liquid distributor 23 and the two are interconnected. The liquid distributor 23 has two through holes and is connected to the material pipe through a conduit. In this embodiment, a cooling system is provided to adjust the temperature of the liquid when it needs to be injected into the pressure tank. More specifically, the temperature of the liquid needs to be adjusted whether it is entering or exiting the pressure tank. For example, when entering the pressure tank, the temperature of the liquid should be lower so that the temperature of the liquid will not be too high after pressurization. Similarly, if the temperature of the liquid discharged after pressurization is too high, it may cause burns to professionals. Therefore, cooling treatment is also required to effectively avoid the adverse effects of temperature.

[0020] To achieve the above objectives, the thermostat 22 is connected to the base via a receiving groove 24. A limiting plate 25 is provided on one side of the receiving groove 24, and a fixing hole adapted to the thermostat is provided on the limiting plate 25. A pulley adapted to the receiving groove is provided on the edge of the thermostat 22. In this embodiment, a receiving groove is provided, and a groove is provided at the edge of the receiving groove. This allows the thermostat to slide along the groove, facilitating maintenance. The presence of the limiting plate ensures that when the thermostat moves to the set position, it is fixed to the receiving groove through the fixing hole, preventing it from shifting.

[0021] The base includes an upper base 4 and a lower base 5, which are fixedly connected as a single unit. One side of the lower base 5 extends outward to form an extension, on which a guide rail is provided for the parallel movement of the pressure tank 6. The upper base 4 is provided with a sealing component 3 adapted to the pressure tank 6. The pressure tank 6 has an internal partition structure, and a material ring is provided on the side of the pressure tank 6 facing the plug. The material ring is fixed to the pressure tank and has a material inlet for material flow. The partition structure is located inside the pressure tank 6 and moves along the inside of the pressure tank 6. The upper base 4 has a "U"-shaped structure, with the pressure tank 6 located in the middle of the upper base 4. Sealing components 3 are provided at both ends of the upper base 4, with the plug extending into the material ring and tightly fitting against the inner side of the material ring. The material ring has two material interfaces, including an inlet and an outlet, which are offset from each other on the material ring. In this embodiment, the special structural design of the upper base allows it to effectively enclose the cavity. During ultra-high pressure sterilization, the sealing component can effectively enter the cavity, meeting the sealing requirements. A sealing ring is provided on the plug, ensuring a tighter fit between the plug and the material ring and preventing pressure leakage. More specifically, the material ring has two material interfaces: an inlet and an outlet, which are offset from each other. In this embodiment, since the cavity is completely sealed, the material ring is used to feed liquid into the cavity. The inlet and outlet of the material ring are connected to external equipment, and under pressure, the liquid material is injected into the cavity. The offset arrangement of the inlet and outlet ensures that material entering the cavity from the inlet does not directly affect the outlet, allowing it to enter the cavity. The material is only discharged from the outlet after the cavity is completely filled.

[0022] The drive structure includes telescopic rods 34, a first moving plate 35, and a telescopic motor 33. Multiple telescopic rods 34 are provided, with one end connected to the telescopic motor 33 fixed to the upper base and the other end fixedly connected to the first moving plate 35. A plug 31 is fixedly installed in the middle of the first moving plate 35. In this embodiment, the plug 31 is fixed to the first moving plate 35. One end of the first guide rod 341 is connected to the rear seat plate 36, and the other end is connected to the first moving plate 35. That is, during installation and use, the telescopic rod of the telescopic motor 33 points towards the rear seat plate, and then the tension and propagation are transmitted to the first moving plate through the first guide rod connected to the rear seat plate. The first moving plate then drives the plug to move. This allows for better limitation of the movement position and better dispersion of the reaction force. In this embodiment, the upper base includes a support frame 32, on which a transverse strip 321 is provided to fix the telescopic motor, and a reinforcing rib 322 is provided to ensure the stability of the fixation. A positioning rod is provided on the first moving plate 35, and a positioning hole adapted to the positioning rod is provided on the pressure tank, thereby realizing the accurate docking of the plug and the cavity. The lower base is also provided with a cylinder pull rod 37 and a positioning pin 38. When the cylinder pull rod moves to the appropriate position, the positioning pin penetrates into the limiting hole of the cylinder pull rod, thereby realizing the left and right positioning of the pressure tank, so that there is no concern about the pressure tank shifting during the loading and unloading process. In the specific implementation process, there are four first guide rods 341, which are evenly distributed and connected to the first moving plate 35 and the rear seat plate 36, and each first guide rod is parallel to each other; the telescopic motor is a single-rod hydraulic cylinder, and the moving rod is equidistant from the two first guide rods on the same vertical plane. The single-rod hydraulic cylinder can match the pressure in the pressure chamber when injecting oil pressure, achieving a smooth sealing effect; and the first guide rods are evenly distributed on the rectangular rear seat plate, forming a symmetrical and stable force transmission structure; ensuring stable movement and good sealing effect. In this embodiment, the plug 31 includes a cylindrical plug end and a base end. The diameter of the base end is larger than the size of the cylindrical plug end, and the cylindrical plug end passes through the fixing hole in the front seat plate, while the base end is abutted and fixed to the front seat plate.

[0023] The pressure tank 6 is equipped with a partition structure, which includes a piston 61. The piston's cylindrical surface has a first annular groove 62. The piston 61 is symmetrical about the first annular groove 62. The end face of the piston 61 is concave to form an end face groove 611. A positioning post 612 is formed by a protrusion in the middle of the end face groove 611, and a magnet 64 is fitted onto the positioning post 612. Two sealing rings 621 are installed in the first annular groove 62, and the sealing rings 621 are respectively tightly attached to the side wall of the first annular groove. The two sealing rings 621 are symmetrically arranged. Piston annular grooves 63 are respectively provided on both sides of the first annular groove, and guide rings 631 are fitted into the piston annular grooves 63. In this embodiment, since the pressurization process in the pressure chamber ultimately aims to achieve pressure balance between the two partition chambers, the partition device needs mechanical stability to ensure that the pressure changes on both sides are equal, thereby guaranteeing the safety of the device during use. To prevent issues like cracking at one end, two sealing rings are necessary. These rings are tightly fitted to the sidewall of the first annular groove to create contact pressure. The two sealing rings are symmetrically positioned. Since the first annular groove is located in the middle of the piston, stress distribution needs to be well-released. The sealing rings effectively release this stress and allow for better contact with the inner wall of the external pressure chamber. The double sealing rings are arranged back-to-back with a certain gap between them, providing buffer space when the external pressure changes gradually. Furthermore, the medium contacted by the sealing rings is not direct contact, but rather residual medium that may exist on the inner wall of the pressure chamber. Therefore, the sealing rings can both maintain pressure and scrape off residual medium from the inner wall of the pressure chamber. The use of two sealing rings also ensures that the piston maintains its overall symmetrical structure.

[0024] In this embodiment, the end face of the piston 61 is recessed to form an end face groove 611, and the center of the end face groove 611 protrudes to form a positioning post 612. A magnet 64 is fitted onto the positioning post 612, and the magnet 64 is used for positioning sensing by an external sensor. Because the working environment inside the pressure chamber is under ultra-high pressure, no sensor can work in this chamber. Therefore, it is necessary to measure the pressure through a combination of internal and external sensors. In order to ensure a relatively large chamber volume and a relatively stable fixing structure, a magnet is fixed in the groove to reduce the stress distortion area and prevent ultra-high pressure risks.

[0025] In this embodiment, the magnet 64 is fixed to the positioning post with screws, and the end face of the magnet is coplanar with the end face of the piston. This ensures accurate positioning of the piston and prevents contamination of the medium and materials within the ultra-high pressure chamber. Furthermore, to ensure good symmetry and stability in the piston's mechanical properties, the magnet is flush with the piston end face after installation, preventing any pressure abrupt changes and improving structural stability. Preferably, the sidewalls of the end face groove and adjacent surfaces have an arc-shaped transition. More preferably, the orthographic projection of the magnet coincides with the end face of the positioning post, preventing abrupt pressure changes between the positioning post and the magnet and ensuring connection stability. The positioning post also has an arc-shaped transition with the bottom surface of the end face groove.

[0026] In this embodiment, the two sealing rings 621 are Y-shaped sealing rings. The lips of the Y-shaped sealing rings abut against the sidewall of the first annular groove. The bottom gap H of the two sealing rings is set and they are adjacent. Since the lips of the Y-shaped sealing rings are of different lengths, preferably, the lips of the Y-shaped sealing rings include a short lip and a long lip, with the long lip located on the side of the short lip away from the piston. The long lip slightly protrudes from the first annular groove. The Y-shaped sealing ring adheres to the mating surface of the sealing pair by its open lip. When there is no internal pressure, only a small contact pressure is generated due to the deformation of the lip tip. Under sealing conditions, there is a normal pressure equal to the pressure of the medium at every point in contact with the sealing medium. Therefore, the bottom of the lip ring will be subjected to axial compression, the lip will be subjected to circumferential compression, the contact with the sealing surface will widen, and the contact stress will increase. When the internal pressure increases further, the distribution and magnitude of the contact pressure will change further, the lip will fit more tightly with the sealing surface, and the sealing performance will be better. Experiments under ultra-high pressure conditions have revealed that the lip of the U-ring may become concave under high pressure, thus creating a gap. The bottom of the Y-ring is thicker, and the lip varies in length. Therefore, when using back-to-back installation, the higher the pressure, the better the sealing effect.

[0027] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
