Description

Technical Field

[0001] The present invention belongs to the technical field of food processing, and in particular, relates to a high-pressure sterilization device for food processing. Background Art

[0002] High-pressure sterilization tanks play an important role in the food industry, especially in the production process of noodles (such as dried noodles). Their main function is to eliminate microorganisms and enzymes in products through high temperature and high pressure, thereby extending the shelf life of products and ensuring food safety. The packaged food is placed into the high-pressure sterilization tank, and then the tank body is sealed. By injecting steam or hot water into the tank, the internal temperature is raised to a certain value, usually between 121 °C and 134 °C. After reaching the required temperature, it is necessary to maintain for a period of time to ensure thorough sterilization. After the sterilization process is completed, the pressure is gradually reduced and the food is cooled to avoid deformation or damage of the packaging due to sudden temperature drop. For dried foods such as dried noodles, although their moisture content is low and the risk of microbial growth is small, in order to further ensure food safety and extend the shelf life, high-pressure sterilization technology is also adopted. Especially for pre-packaged dried noodle products, high-pressure sterilization treatment can significantly reduce the potential pathogen risk and improve the safety of the products.

[0003] Traditional high-pressure sterilization equipment usually includes a sealed high-pressure sterilization tank and a supporting heating system, and sterilizes food through high-temperature and high-pressure steam. However, these devices have some limitations in practical applications. For example, traditional high-pressure sterilization equipment usually relies on single-direction turning (such as only horizontal or vertical turning) or static placement to achieve sterilization. This design cannot ensure that all parts of the food can fully contact high-temperature and high-pressure steam. Due to poor steam flow, it is easy to accumulate in some areas, resulting in local overheating or cold spots. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-pressure sterilization device for food processing to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A high-pressure sterilization device for food processing, including a high-pressure sterilization tank and a tank cover installed at the top of the high-pressure sterilization tank. A food sterilization and loading mechanism for loading food to be processed is arranged in the inner cavity of the high-pressure sterilization tank. The food sterilization and loading mechanism includes two turntables symmetrically connected with a spacing therebetween, a plurality of multi-directional rotation components movably installed in an annular array between the two turntables, and sterilization baskets installed in each multi-directional rotation component; The sterilization basket contains the food to be processed. The lower part of the outer sides of the two turntables is rotatably installed and supported by a U-shaped support frame. A second servo motor is installed on the outer wall of one side of the U-shaped support frame. The output shaft of the second servo motor penetrates through the U-shaped support frame and is fixedly connected to the turntable. An elevating mechanism is arranged between the bottom surface of the U-shaped support frame and the inner bottom wall of the high-pressure sterilization tank. The elevating mechanism drives the U-shaped support frame and the turntable to move up and down longitudinally in the high-pressure sterilization tank. The periphery of the U-shaped support frame is also connected to the inner wall of the periphery of the high-pressure sterilization tank through a longitudinal positioning component, so that the lifting of the turntable and the U-shaped support frame can be positioned and anti-tilt.

[0006] Preferably in this solution, a connecting shaft is fixed between the centers of the two turntables, and the output shaft of the second servo motor is fixedly connected to one end of the connecting shaft.

[0007] Preferably in this solution, a fixed ring body is integrally connected to the top of the sterilization basket, and a detachable cover plate is detachably connected inside the fixed ring body, and the food to be processed is placed in the sterilization basket and closed by the detachable cover plate.

[0008] Preferably in this solution, first ball bearings are fixedly embedded in the upper parts of both ends of the U-shaped support frame, and the smooth rod ends on the opposite sides of the two turntables are in interference fit with the inner rings of the first ball bearings.

[0009] Preferably in this solution, support cross beams are integrally connected to both sides of the U-shaped support frame. The longitudinal positioning component includes positioning sliders respectively welded to the opposite ends of the two support cross beams and two U-shaped positioning tracks symmetrically welded to the inner wall of the high-pressure sterilization tank. The positioning sliders are adapted to slide longitudinally in the U-shaped positioning tracks.

[0010] Preferably in this solution, a first servo motor is installed in the middle of the top surface of the tank cover. The output shaft of the first servo motor longitudinally penetrates through the tank cover and is fixedly connected to a rotating shaft. A cross-shaped support rod is welded to the bottom end of the rotating shaft, and centrifugal cyclone blades are installed on the bottom surfaces of the four free ends of the cross-shaped support rod through bolts.

[0011] Preferably in this solution, the multi-directional rotation assembly includes a plurality of sealed bearings rotatably installed in an annular array between the two turntables and a plurality of second ball bearings fixedly embedded in the inner walls of the two turntables. The sterilization basket is in interference fit with the inner rings of the sealed bearings. Pin shafts are symmetrically welded to the periphery of the outer rings of each sealed bearing, and each pin shaft is in interference fit with the inner ring of the second ball bearing.

[0012] Preferably in this solution, guide wind plates are welded to the top surface of each detachable cover plate and the bottom surface of the sterilization basket.

[0013] Preferably, the lifting mechanism includes an extended top column welded to the middle of the bottom surface of the U-shaped support frame, a protective sleeve welded to the inner bottom wall of the autoclave, and a hydraulic lifting column longitudinally fixed in the inner cavity of the protective sleeve. The extended top column is inserted into the protective sleeve.

[0014] Preferably, a dust exhaust pipe for discharging waste water and impurities is connected through the bottom surface of the autoclave, and a pressure relief pipe is installed on the top surface of the tank cover.

[0015] Compared with the prior art, the technical effects and advantages of the present invention are as follows: In this high-pressure sterilization device for food processing, the second servo motor drives the coupling shaft, which in turn drives the turntable to rotate slowly. A plurality of multi-directional rotation components are installed on each turntable. These components allow the sterilization basket to rotate inside it. The rotation of the turntable causes the sterilization basket to start shaking slightly, prompting the food to be initially turned over in the basket, preparing for subsequent deeper processing. This initial turning helps to break the adhesion between food pieces, making it easier for steam to penetrate, and further improving the sterilization efficiency.

[0016] The multi-directional rotation components include sealed bearings and second ball bearings. These components enable the sterilization basket to not only rotate circumferentially on the turntable but also freely flip in multiple directions. This design greatly increases the contact area between the food and the steam, thereby improving the sterilization effect. Traditional single-direction flipping cannot achieve such an effect because the food may accumulate in some areas, resulting in incomplete sterilization.

[0017] The hydraulic lifting column realizes the height adjustment of the U-shaped support frame through the cooperation of the extended top column and the protective sleeve. This enables the entire food sterilization bearing mechanism to move up and down in the autoclave. The lifting mechanism can adjust the height as needed to ensure the uniform distribution of steam throughout the autoclave. Traditional equipment is usually fixed in one position, which easily causes uneven steam distribution, resulting in insufficient sterilization in some areas. However, this design solves this problem through dynamic adjustment and improves the overall sterilization effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known to those skilled in the art are not described.

[0022] Unless otherwise defined, the directions such as up, down, left, right, front, back, inside and outside involved herein are based on the up, down, left, right, front, back, inside and outside in the figures shown in the present invention, and are hereby explained together.

[0023] This embodiment provides as Figures 1 to 9A high-pressure sterilization device for food processing as shown includes a high-pressure sterilization tank 1 and a tank cover 2 installed at the top of the high-pressure sterilization tank 1. A food sterilization and loading mechanism 11 for loading food to be processed is arranged in the inner cavity of the high-pressure sterilization tank 1. The food sterilization and loading mechanism 11 includes two disks 12 symmetrically connected with a spacing therebetween, a plurality of multi-directional rotation components 20 movably installed in an annular array between the two disks 12, and sterilization baskets 19 installed in each multi-directional rotation component 20. The sterilization baskets 19 contain food to be processed (such as noodles). The lower outer sides of the two disks 12 are rotatably supported by a U-shaped support frame 13. A second servo motor 17 is installed on one outer wall of the U-shaped support frame 13. The output shaft of the second servo motor 17 penetrates through the U-shaped support frame 13 and is fixedly connected to the disk 12. A lifting mechanism 14 is arranged between the bottom surface of the U-shaped support frame 13 and the inner bottom wall of the high-pressure sterilization tank 1. The lifting mechanism 14 drives the U-shaped support frame 13 and the disk 12 to move up and down longitudinally in the high-pressure sterilization tank 1. The circumferential side of the U-shaped support frame 13 is also connected to the inner circumferential wall of the high-pressure sterilization tank 1 through a longitudinal positioning component, so that the lifting of the disk 12 and the U-shaped support frame 13 can be positioned and anti-tilted. Place the food to be processed in the sterilization basket 19, rotate it through the multi-directional rotation component 20 and place it between the two disks 12. The high-pressure sterilization of the high-pressure sterilization tank 1 can perform high-pressure sterilization on the food. At the same time, the disk 12 is driven to rotate by the second servo motor 17 to initially turn and move the food in the sterilization basket 19 and make full contact with the high pressure and high temperature in the high-pressure sterilization tank 1. In addition, through the design of the multi-directional rotation component 20, the sterilization basket 19 can perform multi-directional rotation on the basis of the circumferential rotation of the disk 12 to achieve secondary turning, thereby increasing the contact area with the high-temperature sterilization and further improving the high-pressure sterilization effect. Through the design of the lifting mechanism 14, the entire food sterilization and loading mechanism 11 can be moved and displaced in the high-pressure sterilization tank 1, so that the steam in the high-pressure sterilization tank 1 can circulate, prevent the excessive accumulation of steam inside the high-pressure sterilization tank 1, enable the steam to flow in the entire inner cavity of the high-pressure sterilization tank 1, and improve the high-pressure sterilization effect. The longitudinal positioning component enables the lifting of the disk 12 and the U-shaped support frame 13 to be positioned and anti-tilted, preventing tilting and misalignment during the transportation of the disk 12.

[0024] In this embodiment, a coupling shaft 18 is fixed between the centers of the two disks 12. The output shaft of the second servo motor 17 is fixedly connected to one end of the coupling shaft 18. The coupling shaft 18 transmits the power of the second servo motor 17, ensures the synchronous rotation of the two disks 12, ensures the synchronism between the two disks 12, and avoids mechanical failures or efficiency reduction caused by non-synchronization.

[0025] In this embodiment, a fixing ring body 30 is integrally connected to the top of the sterilization basket 19. A detachable cover plate 31 is detachably connected to the inside of the fixing ring body 30. The food to be processed is placed in the sterilization basket 19 and sealed by the detachable cover plate 31. An internal thread groove 32 is provided on the inner wall of the fixing ring body 30, and an external thread groove 33 that is threadedly adapted to the internal thread groove 32 is provided on the circumferential side of the detachable cover plate 31.

[0026] In this embodiment, first ball bearings 23 are fixedly embedded in the upper parts of both ends of the U-shaped support frame 13, and the smooth rod ends on the opposite sides of the two wheel disks 12 are in interference fit with the inner rings of the first ball bearings 23.

[0027] In this embodiment, support cross beams 15 are integrally connected to both sides of the U-shaped support frame 13. The longitudinal positioning member includes positioning sliders 16 respectively welded to the opposite ends of the two support cross beams 15 and two U-shaped positioning tracks 10 symmetrically welded to the inner wall of the high-pressure sterilizer 1. The positioning sliders 16 slide longitudinally in the U-shaped positioning tracks 10. The positioning sliders 16 slide in the U-shaped positioning tracks 10 to ensure the vertical up-and-down movement of the U-shaped support frame 13. A stable guiding system is provided to prevent the U-shaped support frame 13 from tilting or shifting during the lifting process, improving the reliability and safety of the entire device.

[0028] In this embodiment, a first servo motor 4 is installed in the middle of the top surface of the tank lid 2. The output shaft of the first servo motor 4 longitudinally penetrates the tank lid 2 and is fixedly connected to a rotating shaft 8. A cross support rod 34 is welded to the bottom end of the rotating shaft 8. Centrifugal cyclone vanes 9 are installed on the bottom surfaces of the four free ends of the cross support rod 34 through bolts. The output shaft of the first servo motor 4 and the rotating shaft 8 are connected between the tank lid 2 through a sealed bearing 22, so that the first servo motor 4 is stably installed on the top surface of the tank lid 2. The output shaft of the first servo motor 4 drives the rotating shaft 8 to rotate in the inner cavity of the autoclave 1. The rotating shaft 8 drives the centrifugal cyclone vanes 9 to operate synchronously with the output shaft of the first servo motor 4 through the cross support rod 34, so that the centrifugal cyclone vanes 9 generate centrifugal force by blowing air at high speed in the inner cavity of the autoclave 1, and the air blown by the centrifugal cyclone vanes 9 drives the steam in the inner cavity of the autoclave 1 to flow. This can not only prevent the accumulation of steam, but also actively blow the steam onto the food to achieve active high-pressure sterilization, forming a dual sterilization method with the passive sterilization of the food driven by the turntable 12. The first servo motor 4 drives the rotating shaft 8 and the cross support rod 34 to rotate at high speed, generating a strong centrifugal force, promoting the flow of steam, enhancing the circulation effect of steam, preventing the accumulation of steam, improving the sterilization efficiency, realizing active ventilation, and further improving the sterilization quality. The first servo motor 4 drives the rotating shaft 8 and the cross support rod 34 at its end to rotate at high speed, and the centrifugal cyclone vanes 9 on the cross support rod 34 rotate at high speed accordingly, generating a strong centrifugal force, pushing the steam in the autoclave 1 to flow rapidly. The air flow generated by the centrifugal cyclone vanes 9 pushes the steam to flow rapidly, preventing the steam from accumulating in a certain part and ensuring that the steam evenly covers the entire autoclave 1. This active ventilation design significantly enhances the circulation effect of steam, improves the sterilization efficiency and quality.

[0029] In this embodiment, the multi-directional rotation assembly 20 includes a plurality of sealed bearings 22 rotatably installed in an annular array between the two turntables 12 and a plurality of second ball bearings 28 fixedly embedded in the inner walls of the two turntables 12. The sterilization basket 19 is in interference fit with the inner ring of the sealed bearing 22. A pin shaft 29 is symmetrically welded to the circumferential side of the outer ring of each sealed bearing 22, and each pin shaft 29 is in interference fit with the inner ring of the second ball bearing 28. This enables the sterilization basket 19 to rotate in the inner ring of the sealed bearing 22. The pin shafts 29 on both sides of the sealed bearing 22 are respectively connected to two opposite second ball bearings 28 between the two turntables 12, enabling the sealed bearing 22 to flip between the two turntables 12. The sealed bearing 22 allows the sterilization basket 19 to rotate in its inner ring, and the pin shaft 29 ensures its stable flipping between the two turntables 12, providing a flexible rotation mechanism, increasing the multi-directional flipping ability of the sterilization basket 19, improving the contact effect between the food and the steam, and enhancing the sterilization effect.

[0030] In this embodiment, air guide plates 21 are welded to the top surface of each detachable cover plate 31 and the bottom surface of the sterilization basket 19. Due to the design of the air guide plates 21 at the upper and lower ends of the sterilization basket 19, the centrifugal force generated by the high-speed operation of the 4 centrifugal cyclone vanes 9 in the autoclave 1 causes the centrifugal wind force to blow towards the air guide plates 21. Under the design of the multi-directional rotation assembly 20, when the air guide plates 21 receive this wind force, they will drive the sterilization basket 19 to flip in multiple directions between the two turntables 12, thereby further improving the sterilization effect. The air guide plates 21 guide the airflow generated by the centrifugal cyclone vanes 9, promote the steam to flow towards the sterilization basket 19, improve the fluidity of the steam, ensure that the steam evenly covers the surface of the food, further enhance the sterilization effect, and reduce the sterilization time. The first servo motor 4 drives the rotating shaft 8 and the cross support rod 34, drives the centrifugal cyclone vanes 9 to rotate at high speed, generates a strong centrifugal force, promotes the rapid flow of steam, and prevents the accumulation of steam. The airflow generated by the centrifugal cyclone vanes 9 not only pushes the steam to flow, but also has a certain disturbing effect on the sterilization basket 19 and the food inside it, assisting the flipping of the food in the basket and further enhancing the sterilization effect.

[0031] In this embodiment, the lifting mechanism 14 includes an extended top column 24 welded to the middle of the bottom surface of the U-shaped support frame 13, a protective sleeve 26 welded to the inner bottom wall of the autoclave 1, and a hydraulic lifting column 25 longitudinally fixed in the inner cavity of the protective sleeve 26. The extended top column 24 is inserted into the protective sleeve 26. The top end of the hydraulic lifting column 25 is welded with a connection plate 27. The connection plate 27 is fixedly connected to the bottom surface of the extended top column 24 by bolts, so that the hydraulic lifting column 25 can be telescopically lifted in the protective sleeve 26, thereby driving the extended top column 24 and the U-shaped support frame 13 to lift, and positioning the lifting of the U-shaped support frame 13 through the longitudinal positioning component. The hydraulic lifting column 25 adjusts the height of the extended top column 24 through telescopic movement, thereby controlling the lifting of the U-shaped support frame 13, providing an accurate height adjustment function, ensuring the even distribution of steam, enhancing the flexibility and adaptability of the system, and being applicable to food processing requirements of different sizes.

[0032] In this embodiment, support feet 5 are welded to the bottom surface of the autoclave 1. A dust exhaust pipe 7 for discharging waste water and impurities is also connected through the bottom surface of the autoclave 1. A valve is provided inside the dust exhaust pipe 7. A distribution box 6 is installed on the peripheral side of the lower part of the autoclave 1. A PLC for controlling the opening and closing of the above electrical components is provided in the distribution box 6. A pressure relief pipe 3 is installed on the top surface of the tank cover 2.

[0033] Working principle For the high-pressure sterilization device for food processing, carefully place the food to be processed into the sterilization basket 19, ensuring even distribution of the food to promote optimal sterilization effect. Use the fixed ring body 30 and the detachable cover plate 31 for sealing, and ensure a tight seal through the internal thread path 32 and the external thread path 33. Place and lock the tank cover 2 accurately on the top of the autoclave 1 to ensure its complete seal. At this time, the pressure relief pipe 3 should be in the initial position, ready to adjust the internal pressure.

[0034] Start the system through the control panel on the distribution box 6 to activate the PLC control system. The PLC will start each component in sequence according to the preset program. The second servo motor 17 starts, driving the coupling shaft 18, and then driving the turntable 12 to rotate slowly. A plurality of multi-directional rotation components 20 are installed on each turntable 12. These components allow the sterilization basket 19 to rotate inside it. The rotation of the turntable 12 causes the sterilization basket 19 to start shaking slightly, prompting the food to be initially turned over in the basket, preparing for subsequent deeper processing.

[0035] The multi-directional rotation component 20 includes a sealed bearing 22 and a second ball bearing 28. These components enable the sterilization basket 19 to not only rotate circumferentially on the turntable 12 but also freely flip in multiple directions. This design greatly increases the contact area between the food and the steam, improving the sterilization efficiency. The pin shaft 29 ensures the stable flipping of the sterilization basket 19 between the two turntables 12, preventing any possible tilting or misalignment.

[0036] The first servo motor 4 starts, driving the rotating shaft 8 and the cross support rod 34 at its end to rotate at high speed. The centrifugal cyclone blades 9 on the cross support rod 34 rotate at high speed accordingly, generating a strong centrifugal force. The airflow generated by the centrifugal cyclone blades 9 pushes the steam in the autoclave 1 to flow rapidly, preventing the steam from accumulating in a certain part. At the same time, the air guide plates 21 are located at the upper and lower ends of the sterilization basket 19 to help guide the airflow and further enhance the contact between the steam and the food.

[0037] The hydraulic lifting column 25 realizes the height adjustment of the U-shaped support frame 13 through the cooperation of the extension top column 24 and the protective sleeve 26. This enables the entire food sterilization loading mechanism 11 to move up and down inside the autoclave 1. The positioning slider 16 slides along the U-shaped positioning track 10 to ensure the stability of the U-shaped support frame 13 and the turntable 12 during movement, avoiding any unnecessary tilting or misalignment.

[0038] After sterilization is completed, the PLC control system will automatically open the valve on the dust exhaust pipe 7 to discharge wastewater and impurities. Subsequently, gradually release the pressure inside the autoclave 1 until it returns to the atmospheric pressure state. Open the tank cover 2 and take out the food that has completed sterilization. Thoroughly clean the inside of the autoclave 1, including removing residual water vapor and impurities, to prepare for the next operation. Finally, turn off all electrical equipment.

[0039] It should be noted that in this text, relational terms such as "one" and "two" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising said element.
