Description

Technical Field

[0001] This utility model relates to the field of fruit juice production technology, and in particular to a feeding device for HPP sterilization equipment and an HPP sterilization equipment having the feeding device for HPP sterilization equipment. Background Technology

[0002] High Pressure Processing (HPP) is a technology that uses ultra-high pressure for sterilization and preservation. It involves subjecting packaged food to a static liquid pressure of 100-600 MPa for a certain period of time to destroy enzymes, sterilize, and improve the structure and properties of the material. Its sterilization mechanism is to kill a large number of pathogenic and spoilage bacteria in fruit juice by changing the protein and enzyme structure of microbial cells and inhibiting enzyme activity, without causing damage to nutrients or changes in flavor. Therefore, HPP technology is widely used in fruit juice production.

[0003] Chinese utility model patent CN222217156U discloses an ultra-high pressure sterilization device, including a high-pressure chamber. A slide rail extending axially within the high-pressure chamber has multiple material placement chambers sliding along it. Sealing valves I, II, III, and IV are arranged sequentially along the high-pressure chamber's axial direction within the chamber. A feeding chamber is formed between sealing valves I and II, a sterilization chamber between sealing valves II and III, and a material removal chamber between sealing valves III and IV. An ultra-high pressure pump is connected to the feeding chamber and the material removal chamber via a high-pressure pipe. A drive mechanism within the high-pressure chamber drives the material placement chambers to move axially within the chamber. This ultra-high pressure sterilization device can simultaneously perform pressurization, ultra-high pressure sterilization, and depressurization, thereby continuously performing ultra-high pressure sterilization.

[0004] The ultra-high pressure sterilization equipment disclosed in the above-mentioned utility model patent requires the product to be sterilized to be placed in the storage chamber. The product needs to be packaged before being placed in the storage chamber. However, there are gaps between the product packaging in the storage chamber, resulting in low utilization of the storage chamber. Furthermore, after ultra-high pressure sterilization, the operation of taking the product packaging out of the storage chamber one by one is cumbersome and affects production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a material feeding device for HPP sterilization equipment, which solves the problems of low utilization rate of the material feeding chamber and cumbersome operation of removing product packaging in existing technologies.

[0006] According to an embodiment of this utility model, a feeding device for HPP sterilization equipment includes a feeding bin with multiple through holes spaced apart, a bin cover, a guide pipe and a flexible inner liner communicating with the guide pipe, the bin cover covering the opening of the feeding bin and the flexible inner liner located within the space enclosed by the feeding bin and the bin cover; the feeding bin has at least two movable limiting plates, each with a limiting protrusion on the side near the bin cover and a groove on the bin cover cooperating with the limiting protrusion; the feeding bin also has a guide cylinder with a movable... The movable rods are numbered the same as the limiting plates and abut against the limiting plates one by one. Each movable rod is also equipped with a limiting pin perpendicular to the movable rod. The guide cylinder is equipped with a guide groove and a limiting groove that are connected. The limiting pins extend into the guide grooves and the length direction of the guide grooves is consistent with the movement direction of the limiting plates. The limiting grooves are located at the end of the guide grooves near the cover plate and the length direction of the limiting grooves is consistent with the circumference of the guide cylinder. When the movable rods are moved so that the limiting pins move into the limiting grooves within the guide grooves, the movable rods push the limiting plates toward the direction of the cover plate and cause the limiting protrusions to extend into the grooves.

[0007] Furthermore, the material storage bin is provided with a stepped portion, which is located near the opening of the material storage bin, and the bin cover plate abuts against the stepped portion.

[0008] Furthermore, the limiting plate is provided with a guide rod, and the material storage bin is provided with a guide hole that cooperates with the guide rod.

[0009] Furthermore, a spring is sleeved on the guide rod, and the opposite ends of the spring in the extension direction respectively abut against the limiting plate and the material storage bin, driving the limiting plate to move away from the bin cover plate.

[0010] Furthermore, the material storage bin is threadedly connected to an end cap, which is located at the end of the guide rod away from the bin cover plate.

[0011] Furthermore, an operating head is fixedly connected to the movable rod, and the operating head is located at the end of the movable rod away from the limiting plate.

[0012] Furthermore, the cover plate is also provided with a sealing cap and a sealing ring. The sealing cap covers the opening of the guide pipe, and the sealing ring is threadedly connected to the guide pipe and presses the sealing cap onto the guide pipe.

[0013] Furthermore, the hopper cover is provided with two handles spaced apart, and the two handles are respectively located on both sides of the feed tube.

[0014] On the other hand, according to an embodiment of the present invention, an HPP sterilization device is also provided, including the above-mentioned feeding device for HPP sterilization device.

[0015] Compared with existing technologies, this utility model has the following advantages: By using a material storage bin and a cover plate to form a space for accommodating a flexible inner liner, the product to be sterilized is filled into the flexible inner liner through a feed pipe. Placing the flexible inner liner into the material storage bin allows the product to undergo ultra-high pressure sterilization in the ultra-high pressure sterilization equipment, thus fully utilizing the space within the material storage bin. After the cover plate is placed in the material storage bin, pushing the movable rod moves the limiting plate to push the limiting protrusion into the groove on the cover plate. During the movement of the limiting plate towards the cover plate, the limiting pin moves to the end connecting the guide groove and the limiting groove. After the limiting protrusion engages with the groove, rotating the movable rod causes the limiting pin to engage in the limiting groove. The position of the limiting plate can be locked, thereby locking the position of the bin cover on the material storage bin through the cooperation of the limiting protrusion and the groove, so that the position of the flexible inner liner in the material storage bin remains stable. After the ultra-high pressure sterilization process is completed, first rotate the movable rod to make the limiting pin exit the limiting groove and enter the guide groove, then move the movable rod and move the limiting plate to make the limiting plate move away from the bin cover, so that the limiting protrusion exits the groove. Then the bin cover, flexible inner liner and processed product can be taken out together. It solves the technical problems of low utilization rate of the material storage bin and cumbersome operation of product packaging removal in existing ultra-high pressure sterilization equipment, and produces the technical effect of ensuring that the space in the material storage bin is fully utilized and facilitating product loading and unloading.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a material placement device for HPP sterilization equipment, which is used to place the product to be processed during the ultra-high pressure sterilization process.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 The feeding device for the HPP sterilization equipment includes a feeding bin 1 with multiple through holes 11 spaced apart, and a bin cover 2. The bin cover 2 is provided with a guide pipe 21 and a flexible inner liner 3 communicating with the guide pipe 21. The bin cover 2 covers the opening of the feeding bin 1 and the flexible inner liner 3 is located within the space enclosed by the feeding bin 1 and the bin cover 2. The product to be processed can be poured into the flexible inner liner 3 through the guide pipe 21, and the flexible inner liner 3 can expand to abut against the inner wall of the feeding bin 1 as the product is injected, so that the feeding bin 1 can hold as much product as possible and make full use of the space in the feeding bin 1. The material storage bin 1 is provided with at least two movable limiting plates 4. Each limiting plate 4 has a limiting protrusion 41 on its side near the bin cover plate 2, and the bin cover plate 2 has a groove 22 that mates with the limiting protrusion 41. The material storage bin 1 is also provided with a guide cylinder 12, and the guide cylinder 12 contains movable rods 5. The number of movable rods 5 is the same as the number of limiting plates 4, and each rod abuts against one of the limiting plates 4. Each movable rod 5 is also provided with a limiting pin 51 perpendicular to it. The guide cylinder 12 has a communicating guide groove 13 and a limiting groove 14. The limiting pin 51 extends into the guide groove 13, and the length direction of the guide groove 13 is consistent with the moving direction of the limiting plate 4. The limiting groove 14 is located at the end of the guide groove 13 near the bin cover plate 2, and the length direction of the limiting groove 14 is consistent with the moving direction of the guide cylinder. When the movable rod 5 moves in the circumferential direction of the guide groove 13 towards the limiting groove 14, the movable rod 5 pushes the limiting plate 4 towards the bin cover 2 and causes the limiting protrusion 41 to extend into the groove 22. At this time, the position of the bin cover 2 on the storage bin 1 can be locked by the cooperation between the limiting protrusion 41 and the groove 22. When the limiting pin 51 moves to the end where the guide groove 13 and the limiting groove 14 are connected, the limiting protrusion 41 fits against the inner wall of the groove 22. Rotating the movable rod 5 so that the limiting pin 51 is engaged in the limiting groove 14 can lock the position of the movable rod 5 while keeping the limiting protrusion 41 in the groove 22, preventing the bin cover 2 or the flexible inner liner 3 from moving unexpectedly during the ultra-high pressure sterilization process.

[0021] Specifically, the operation steps for placing products using the feeding device for the HPP sterilization equipment provided in this embodiment are as follows: The product to be sterilized is filled from the feed tube 21 into the flexible inner liner 3, and then the flexible inner liner 3 is placed into the feeding bin 1. Alternatively, the flexible inner liner 3 can be placed into the feeding bin 1 first, and then the product can be filled into the flexible inner liner 3. When the flexible inner liner 3 is placed into the feeding bin 1, the bin cover plate 2 covers the opening of the feeding bin 1. Then, the movable rod 5 is pushed to move the limiting plate 4 to push the limiting protrusion 41 into the groove 22. During the movement of the limiting plate 4 towards the bin cover plate 2, the limiting pin 51 moves to the guide groove 13 and the limiting groove 1. At one end of the connection, after the limiting protrusion 41 engages with the groove 22, rotating the movable rod 5 causes the limiting pin 51 to engage with the limiting groove 14, thereby locking the position of the limiting plate 4 and simultaneously locking the position of the bin cover 2 on the storage bin 1. Then, the ultra-high pressure sterilization equipment is started to process the product in the storage bin. After the ultra-high pressure sterilization process is completed, first rotate the movable rod 5 to make the limiting pin 51 exit the limiting groove 14 and enter the guide groove 13, then move the movable rod 5 and move the limiting plate 4 to make the limiting protrusion 41 exit the groove 22, so that the bin cover 2, the flexible inner liner 3, and the processed product can be taken out together from the storage bin 1. The storage device for the HPP sterilization equipment provided in this embodiment can ensure that the space in the storage bin 1 is fully utilized, thereby reducing energy consumption, and making product loading and unloading convenient and easy to operate.

[0022] like Figure 3 and Figure 4 As shown, the storage bin 1 is provided with a stepped portion 15, which is located near the opening of the storage bin 1, and the bin cover plate 2 abuts against the stepped portion 15. The stepped portion 15 is used to support and position the bin cover plate 2, so that the bin cover plate 2 remains stable on the storage bin 1. At the same time, after the bin cover plate 2 is placed on the stepped portion 15, the limiting protrusion 41 is aligned with the groove 22, ensuring that the limiting protrusion 41 can smoothly enter the corresponding groove 22 when the limiting plate 4 moves.

[0023] like Figure 4 As shown, the limiting plate 4 is provided with a guide rod 42, and the material storage bin 1 is provided with a guide hole that cooperates with the guide rod 42. The limiting plate 4 is installed on the material storage bin 1 by the cooperation of the guide rod 42 and the guide hole, and the movement direction of the limiting plate 4 on the material storage bin 1 is restricted, preventing the limiting plate 4 from deviating from the preset direction when moving, which would cause the limiting protrusion 41 to fail to cooperate with the groove 22.

[0024] In this embodiment, a spring 43 is sleeved on the guide rod 42. The opposite ends of the spring 43 in the extension and retraction direction respectively abut against the limiting plate 4 and the material storage bin 1, driving the limiting plate 4 to move away from the bin cover plate 2. The elastic force provided by the spring 43 keeps the limiting plate 4 abutting against the movable rod 5. When the limiting plate 4 moves under the push of the movable plate, causing the limiting protrusion 41 to enter the groove 22, the spring 43 is further compressed. During the removal of the flexible inner liner 3, as the movable rod 5 moves, the spring 43 gradually returns to its original length and pushes the limiting plate 4 away from the bin cover plate 2, so that the limiting protrusion 41 automatically exits the groove 22, making it easier to remove the bin cover plate 2 from the material storage bin 1.

[0025] Please refer to Figure 1 and Figure 4 An end cap 16 is threaded onto the material storage bin 1, and the end cap 16 is located at the end of the guide rod 42 away from the bin cover plate 2. The end cap 16 is used to form a sealed space with the material storage bin 1 to accommodate the spring 43 and part of the guide rod 42, preventing the pressurizing medium used in the ultra-high pressure sterilization process from contacting the spring 43, which helps to improve the reliability of the material storage device for the HPP sterilization equipment.

[0026] like Figure 2 As shown, an operating head 52 is fixedly connected to the movable rod 5, and the operating head 52 is located at the end of the movable rod 5 away from the limiting plate 4. The operating head 52 is used to control the movement and rotation of the movable rod 5, so as to facilitate the manipulation of the movable rod 5 to push the limiting plate 4 to move, thereby facilitating the operation of the feeding device for the HPP sterilization equipment.

[0027] Please combine Figure 3 and Figure 5 The cover plate 2 is also provided with a sealing cap 23 and a sealing ring 24. The sealing cap 23 covers the opening of the feed tube 21, and the sealing ring 24 is threadedly connected to the feed tube 21 and presses the sealing cap 23 onto the feed tube 21. The sealing cap 23 is used to close the feed tube 21, and the sealing cap 23 is fixed to the opening of the feed tube 21 through the threaded connection between the sealing tank and the feed tube 21, so as to ensure that the flexible inner liner 3 remains sealed during the ultra-high pressure sterilization process.

[0028] like Figure 1 and Figure 5As shown, the hopper cover 2 is provided with two handles 25 spaced apart, and the two handles 25 are respectively located on both sides of the guide tube 21. The two handles 25 on the hopper cover 2 are used to facilitate pulling the hopper cover 2 out of the storage hopper 1, thereby removing the flexible inner liner 3 from the storage hopper 1, and facilitating the handling of the hopper cover 2.

[0029] On the other hand, this utility model embodiment also provides an HPP sterilization device, including the above-mentioned feeding device for HPP sterilization devices.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
