Description

Technical Field

[0001] The utility model is applied to the technical field of non-thermal sterilization in the food and beverage industry, and particularly relates to a vertical HPP sterilization device. Background Art

[0002] HPP, also known as high-pressure sterilization, utilizes ultrahigh pressure to sterilize and preserve food. Using water or other liquid media as a pressure medium, HPP applies pressure (100 to 1000 MPa) to the liquid. Using pressure as an energy factor, HPP sterilizes food placed in a specially sealed ultrahigh-pressure container at room temperature or low temperature (below 20°C). High pressure can affect cell morphology, such as by rupturing vacuoles and causing irreversible changes. High pressure can also inactivate key enzymes in food ingredients and the microorganisms they contain. Generally, pressures exceeding 300 MPa cause irreversible denaturation of proteins. Ultrahigh pressure also destroys cell membranes. By altering their permeability, high pressure inhibits enzyme activity and the replication of genetic material like DNA, achieving sterilization. HPP sterilization technology can kill a wide range of bacteria, including but not limited to Escherichia coli, Listeria, Vibrio, Anisakis, yeasts and molds, lactic acid bacteria, and psychotrophic bacteria. HPP technology has a wide range of applications, not limited to food processing and sterilization. It also includes debittering grapefruit juice, tenderizing meat, gelatinizing starch, inactivating toxins and toxic proteins, and enhancing the gelling and cellular properties of protein foods. The advantage of this technology is that it is a physical sterilization method that can be used at both room and low temperatures, while effectively preserving the color, aroma, and nutritional quality of food, without the nutritional damage and flavor changes that occur with high-temperature sterilization.

[0003] HPP is an advanced technology that can reduce product processing steps and extend the shelf life of food. Its specific principle is to use purified water at up to 600 MPa to impart a strong, isostatic pressure to the product for a sustained period of time. This pressure is transmitted instantaneously and evenly throughout the product, achieving the same sterilization effect as pasteurization without the use of heat. It also eliminates the heating and cooling steps, shortening the process and saving costs. For example, Chinese Patent Publication No. CN206213200U discloses a horizontal ultra-high pressure isostatic pressing (UHP) system that also sterilizes materials. However, while a horizontal structure is suitable for large quantities of materials, using it to sterilize materials with a volume of less than 50 liters would increase sterilization costs. Therefore, there is a need for a low-cost, vertical HPP sterilization system that utilizes a vertical structure, offers excellent sealing properties, can adaptively adjust seal strength, improves the stability of the UHP, and kills pathogens and spoilage bacteria without heating or the addition of chemical preservatives.

[0029] like Figures 1 to 2 As shown, in this embodiment, the utility model includes a frame 1 and a high-pressure chamber 2 longitudinally arranged at the upper end of the frame 1, a first oil cylinder 3 driven in the horizontal direction is provided at the bottom of the frame 1, a lower plug 4 is provided at the bottom of the high-pressure chamber 2, the action end of the first oil cylinder 3 is provided with a force frame 5, the top of the force frame 5 is provided with a second oil cylinder 6 driven in the vertical direction, the action end of the second oil cylinder 6 is provided with a mounting bracket 7, the mounting bracket 7 is provided with a third oil cylinder 8 driven in the horizontal direction, the action end of the third oil cylinder 8 is provided with a mounting bracket 7, and the action end of the third oil cylinder 8 is provided with a mounting bracket 7. A force-bearing top plate 9 is provided at the working end, and the force-bearing top plate 9 is adapted to the overhead part of the mounting frame 7. An upper plug 10 is provided at the bottom of the mounting frame 7. A supercharger 11 is provided on one side of the frame 1. The output end of the supercharger 11 is connected to the high-pressure chamber 2 through the upper plug 10 via a high-pressure pipe 12. Under the joint action of the first oil cylinder 3, the second oil cylinder 6 and the third oil cylinder 8, the high-pressure chamber 2 is adapted to the frame body of the force-bearing frame 5, and the upper plug 10 is sealed with the top of the high-pressure chamber 2.

[0030] In the initial state, the force frame 5 and the high-pressure chamber 2 are separated, and the external filling machine places the bottled material inside the high-pressure chamber 2. The first oil cylinder 3 drives the force frame 5 to move to the high-pressure chamber 2, and the second oil cylinder 6 drives the mounting frame 7 to move downward. The upper plug 10 is plugged into the upper hole of the high-pressure chamber 2, and the third oil cylinder 8 drives the force top plate 9 to retreat. The force top plate 9 moves into the frame of the force frame 5 to ensure the downward pressure strength of the upper plug 10. Then water is added to the high-pressure chamber 2, and the supercharger 11 starts to work. The ultra-high-pressure liquid medium generated by the supercharger 11 The material enters the interior of the high-pressure chamber 2 through the through hole of the upper plug 10, thereby maintaining pressure and unloading. When the pressure reaches a certain level, the upper plug 10 transmits the pressure to the force frame 5, and the force frame 5 bears all the pressure of the high-pressure chamber 2. After the pressure maintenance is completed, the rapid pressure relief system can reduce the pressure to normal pressure within 5 seconds, and the pressurized medium inside the high-pressure chamber 2 is discharged. The third oil cylinder 8 drives the force top plate 9 away from the frame of the force frame 5, and the second oil cylinder 6 drives the mounting frame 7 to move upward, and the processed material is taken out at this time. The equipment runs a cycle, and the next cycle starts after adding new material.

[0031] like Figures 3 to 6 As shown, in this embodiment, the supercharger 11 includes a fourth oil cylinder 121, and cylinder flanges 13 are provided at both ends of the fourth oil cylinder 121. A high-pressure cylinder 14 is provided at the end of the cylinder flange 13 away from the fourth oil cylinder 121, and an end cover 15 is provided at the end of the high-pressure cylinder 14 away from the cylinder flange 13; a piston 16 is provided inside the fourth oil cylinder 121, and horizontally arranged plunger rods 17 are provided at both ends of the piston 16.

A sealing assembly 20 is arranged between the cylinder flange 13 and the fourth oil cylinder 121. The interior of the cylinder flange 13 is provided with an oil seal module 21, a sealing block 22 and a high-pressure seal 23 in sequence along the axial direction from the inside to the outside; the outer side of the high-pressure cylinder 14 is clearance-fitted with the high-pressure cylinder jacket 24, one end of the high-pressure cylinder jacket 24 is threadedly connected to the cylinder flange 13, and the other end of the high-pressure cylinder jacket 24 is threadedly connected to the end cover 15, and a check valve body 25 with an oblique hole is provided inside the end cover 15, and a valve pad 26 is provided inside the check valve body 25, and an output one-way valve body 27 is provided at one end of the valve pad 26, and an input port 28 is provided on one side of the end cover 15.

[0032] The two sets of cylinder flanges 13 with boss positioning are respectively connected to the two ends of the fourth cylinder 121. Since the high-pressure cylinder 14 and the high-pressure cylinder sleeve 24 are clearance-fitted, the guiding positioning accuracy is high. The high-pressure cylinder sleeve 24 and the cylinder flange 13 are processed with fitting positions and contact positions, so that the fourth cylinder 121, the cylinder flange 13 and the high-pressure cylinder 14 can achieve a high coaxiality; the spherical contact between the high-pressure cylinder 14 and the high-pressure seal 23 forms a metal-to-metal seal, and at the same time, the conical surface of the check valve body 25 contacts the high-pressure cylinder 14 to form a conical hard seal, eliminating the need for soft sealing components, avoiding the problem of regular replacement of soft sealing components, and reducing the operating cost of the ultra-high-pressure supercharger; the positioning accuracy of the cylinder flange 13 and the high-pressure cylinder 14 is high, and the supercharger displacement can be twice that of the traditional ultra-high-pressure supercharger by increasing the length of the fourth cylinder 121, the high-pressure cylinder 14 and the plunger rod 17. Compared with existing ultra-high pressure supercharger technology, the supercharger 11 can simplify the processing technology of the ultra-high pressure supercharger connecting flange and reduce processing costs; the supercharger 11 can be assembled or operated without considering its twisting tendency, thereby improving the stability of the ultra-high pressure supercharger operation.

[0033] like Figures 1 to 2 As shown, in this embodiment, a three-way joint 29 is provided on the top of the stress-bearing frame 5, and a pressure relief water tank 30 is provided on the side of the stress-bearing frame 5. The three ports of the three-way joint 29 are respectively connected to the output end of the supercharger 11, the high-pressure chamber 2, and the pressure relief water tank 30. The three-way joint 29 acts as a diversion. After the pressure maintenance is completed, the rapid pressure relief system of the supercharger 11 can reduce the pressure to normal pressure within 5 seconds, and the pressurized medium in the high-pressure chamber 2 is discharged to the pressure relief water tank 30.

[0034] like Figures 1 to 2 As shown, in this embodiment, a mounting plate 31 is provided on the top of the frame 1, and the lower plug 4 is provided on the top of the mounting plate 31. The mounting plate 31 is connected to the frame 1 through a contour screw 32, and the contour screw 32 is provided with a compression spring 331. The compression spring 331 provides elastic support for the mounting plate 31, ensuring that the first oil cylinder 3 can smoothly drive the force frame 5 to move to the high-pressure chamber 2, thereby achieving the purpose of moving and giving way.

[0035] like Figures 1 to 2As shown, in this embodiment, the force-bearing frame 5 is a square-shaped structure. The first oil cylinder 3 is located at the bottom of the frame 1. The mounting plate 31 is located within the inner frame of the square-shaped structure. Before the second oil cylinder 6 drives the mounting frame 7 downward, a gap exists between the mounting plate 31 and the bottom of the inner frame of the square-shaped structure. The square-shaped structure is used to increase the rigidity of the force-bearing frame 5. When the pressure reaches a certain level, the upper plug 10 transmits the pressure to the force-bearing frame 5, allowing the force-bearing frame 5 to bear the entire pressure of the high-pressure chamber 2.

[0036] like Figures 1 to 2 As shown, in this embodiment, each of the four corners of the bottom of the high-pressure chamber 2 is provided with a fifth oil cylinder 321 that is driven vertically. The fifth oil cylinder 321 is press-fitted against the mounting plate 31. Under normal circumstances, the lower plug 4 maintains a sealed fit with the bottom of the high-pressure chamber 2 for a long period of time. When maintenance is required on the high-pressure chamber 2, the fifth oil cylinder 321 is activated to detach the high-pressure chamber 2 from the mounting plate 31, thereby allowing it to be transported.

[0037] like Figures 7 to 13 As shown, in this embodiment, a sealed cavity 33 is opened inside the high-pressure chamber 2, and the upper plug 10 includes a plug body 34, a buffer plate 35 and a sealing module. The sealing end of the plug body 34 cooperates with the open end of the sealed cavity 33, and the buffer plate 35 is arranged at the bottom of the sealing end of the plug body 34. A stepped groove 37 is provided in the middle of the sealing end of the plug body 34. The sealing module is arranged on the stepped groove 37. The sealing module includes a U-shaped sealing ring 38, a copper seal of the chamber cover, and a sealing module. A sealing ring 39, a supporting ring 40 and an O-ring 41, a sealed water channel 42 is provided between the buffer plate 35 and the sealed cavity 33, the buffer plate 35 is provided with a plurality of water inlet holes 43 and a sealed water through hole 47, the sealed water channel 42 and the sealed water through hole 47 are respectively matched with the U-shaped sealing ring 38 and the O-ring 41, and a water injection channel 44 is provided in the middle of the plug body 34, and the plurality of water inlet holes 43 are connected to the output end of the supercharger 11 through the water injection channel 44.

[0038] The external filling machine places the bottled material in the sealed cavity 33 and starts the supercharger 11. High-speed water flows into the sealed cavity 33 through the water injection channel 44. The water pressure pushes the O-ring 41 to expand outward, and through the support ring 40, the copper sealing ring 39 of the bin cover can be tightly attached to the inner side of the sealed cavity 33. At the same time, the open end of the U-shaped sealing ring 38 undergoes adaptive deformation and expansion, respectively clamping the inner side of the sealed cavity 33 and the copper sealing ring 39 of the bin cover, thereby realizing secondary adaptive sealing of the high-pressure bin 2.

[0039] like Figures 7 to 13 As shown, in this embodiment, a water inlet connection port 45 is provided at one end of the plug body 34 away from the buffer plate 35 , and the water inlet connection port 45 is connected to the water injection channel 44 , and the output end of the supercharger 11 is connected to the water inlet connection port 45 .

[0040] like Figures 7 to 13 As shown, in this embodiment, the water inlet hole 43 is arranged in the middle of the buffer plate 35, and the water outlet end of the plug body 34 is provided with a water storage stepped groove 46, and the water storage stepped groove 46 cooperates with several of the water inlet holes 43.

[0041] The middle part of the plug body 34 is connected to the inner side of the sealing cavity 33 to complete the preliminary sealing. The high-pressure water flows into the water storage stepped groove 46 through the water injection channel 44 and evenly injects the water into the sealing cavity 33 through the plurality of water inlet holes 43. The water flows through the sealing water channel 42 and the sealing water through hole 4 into the open end of the U-shaped sealing ring 38 and the bottom of the O-shaped sealing ring 41 respectively. As the pressure inside the warehouse body continues to increase, the water pressure will push the U The open end of the O-ring 38 expands outward to press the inner side of the sealing cavity 33 and the copper sealing ring 39 of the bin cover. At the same time, the water pressure will push the O-ring 41 to expand outward, so that the copper sealing ring 39 of the bin cover and the U-ring can be tightly attached to the inner side of the sealing cavity 33. At the same time, the O-ring 41 can prevent water from flowing out of the gap between the copper sealing ring 39 of the bin cover and the stepped groove 37. The greater the pressure, the stronger the sealing. After the pressure is released, the upper plug 10 can be easily removed, which is more efficient.

[0042] like Figures 7 to 13 As shown, in this embodiment, the copper seal ring 39 of the bin cover is connected to the stepped groove 37, the O-ring 41 is disposed at the end of the copper seal ring 39 of the bin cover away from the buffer plate 35 and cooperates with the stepped groove 37, and the support ring 40 is disposed between the end of the copper seal ring 39 of the bin cover away from the buffer plate 35 and the O-ring 41. The end of the copper seal ring 39 of the bin cover that contacts the stepped groove 37 is provided with a guide bevel. High-pressure water enters the gap between the copper seal ring 39 of the bin cover and the stepped groove 37 through the sealing water through-hole 47 and the guide bevel and cooperates with the O-ring 41. The guide bevel is used to prevent bumps or scratches caused by the docking process between the upper plug 10 and the high-pressure bin 2.

[0043] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
