Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a depressurized osmosis salt reduction and preservation device for processing pickled vegetables. Background Technology

[0002] In traditional pickled vegetable processing, a high salt concentration is typically maintained in the production environment to effectively inhibit the growth of harmful microorganisms and extend the product's shelf life. While this high-salt pickling method ensures food safety and storage stability, it also results in a final product with a salt content far exceeding the appropriate standards for modern diets. Long-term excessive consumption can have adverse effects on consumers' health. Therefore, given the reality that it is difficult to completely eliminate the high-salt environment in pickled vegetable production, how to appropriately reduce the salt content of the finished product while ensuring production cycle and food safety, and simultaneously achieve freshness and flavor consistency, has become a pressing technical bottleneck for the industry.

[0003] To reduce the salt content in pickled vegetables, one common method used in the industry is soaking in water for desalination. While this method can remove some salt through osmosis and diffusion, the process is slow and easily leads to the loss of a large amount of water-soluble nutrients and characteristic flavor components, resulting in a bland taste. Furthermore, prolonged soaking increases the risk of microbial contamination, making it difficult to balance salt reduction and preservation. Another common method is to use mechanical pressing or centrifugal force to forcibly squeeze out the juice from the vegetables. This method reduces salt more quickly, but the direct external force on the ingredients easily damages the crisp and tender plant tissues of the pickled vegetables, causing them to become soft, mushy, and broken, severely affecting their appearance and crisp texture. In addition, some factories have tried using running water rinsing, which not only consumes a huge amount of water but also requires large-scale wastewater treatment facilities, making it neither economically nor environmentally sound.

[0004] To overcome the drawbacks of physical contact methods that damage food, a non-contact depressurization osmosis technique utilizing periodic changes in air pressure to reduce salt content has gained increasing attention. The principle involves placing the pickled vegetables in a sealed space and applying alternating positive and negative pressure, or causing pressure fluctuations, forcing the plant cells to continuously expel the high-salt-content cell fluid during the expansion and contraction cycle. This non-contact method effectively avoids mechanical damage and better preserves the original shape of the food. However, existing depressurization osmosis devices still face a series of problems in practical applications. First, during processing, pickled vegetables are often statically stacked, with materials in contact and compressing each other, resulting in uneven pressure transmission. This leads to insufficient salt leaching from the parts of the vegetables inside the stack or attached to the tray, creating obvious processing dead zones. Second, some of the leached salt juice remains on the surface of the vegetables and above the tray, mixing with any subsequent leaching juice to form localized high-concentration areas, affecting the salt reduction efficiency and the uniformity of the finished product's taste. Furthermore, simple decompression osmosis desalination can only remove salt. For batches or parts with different initial curing levels, it cannot simultaneously compensate for flavor and replace internal juices, resulting in inconsistent saltiness and flavor in the same batch of products, making it difficult to achieve quality standardization.

[0005] To improve processing uniformity, some equipment has added a spray system to spray clean water or preparation solution during the salt reduction process. However, most existing spray structures are fixed nozzles with limited coverage, making it difficult to evenly deliver liquid to all material surfaces, especially when the single loading volume is large and there are many stacked layers, where spray blind spots become more prominent. Meanwhile, to reduce material adhesion and promote juice drainage, operators often need to open the lid for manual stirring. This not only reduces the airtightness and continuity of the production process and increases labor intensity, but may also introduce contaminants, affecting preservation. Although a few devices have attempted to integrate mechanical turning mechanisms, the additional power and transmission components significantly increase system complexity, making sealing and corrosion prevention under alternating pressure environments more difficult. Furthermore, the amplitude, angle, and force of turning are often fixed, making it impossible to flexibly adjust according to the texture and shape of different types of pickled vegetables, easily leading to over- or under-turning.

[0006] Furthermore, a thorough cleaning of the interior of the equipment after treatment is a prerequisite for ensuring hygienic and continuous production. Existing equipment often has dead zones where liquid accumulates on the internal loading platform and at the bottom of the casing, resulting in poor drainage of high-salt organic wastewater. Cleaning requires repeated rinsing with large amounts of clean water, which is time-consuming and water-intensive. If cleaning is not thorough, residual salt and vegetable scraps can easily breed microorganisms, threatening the freshness of subsequent batches of products.

[0007] In summary, existing salt reduction and preservation devices and methods for pickled vegetables still have significant shortcomings in terms of material integrity protection, salt reduction uniformity, flavor consistency, anti-adhesion and turning, and convenient cleaning. Therefore, there is an urgent need to develop an integrated depressurization osmosis salt reduction and preservation device that can achieve non-contact deep salt reduction, uniform spray flavoring, no dead corner turning of materials, and convenient cleaning, while ensuring the production cycle and without sacrificing the unique quality of pickled vegetables.

The upper fixing mounting ring on the outer side of the extrusion sealing ring is provided with a plurality of combined mounting holes at equal angles, and the upper fixing mounting ring on the inner side of the extrusion sealing ring is provided with a plurality of positioning guide posts at equal angles.

[0012] As a further embodiment of the present invention: both the combined guide tube and the liquid inlet guide tube are provided with a lower fixing ring at their lower ends. The lower side of the lower fixing ring is provided with a number of annular sealing grooves corresponding to a number of extrusion sealing rings. The lower fixing ring on the outer side of the annular sealing groove is provided with a number of combined mounting holes at equal angles. The combined mounting holes on the upper fixing ring and the lower fixing ring are aligned and fixed with externally provided bolts and nuts. The lower fixing ring is provided with positioning guide holes in conjunction with the positioning guide post.

One end of the limiting rotating column is configured with a synchronous bevel gear on the inner side of the rotating mounting sleeve. An adjusting bevel gear ring is configured on the inner side of the rotating mounting sleeve. The adjusting bevel gear ring meshes with the synchronous bevel gear.

[0016] As a further aspect of the present invention: the other end of the limiting rotating column is provided with a synchronous transmission column in conjunction with the deflection mounting hole, and a deflection air cylinder is provided on the synchronous transmission column in conjunction with the deflection mounting hole. A telescopic air bag is connected to the outside of the deflection air bag, and a flipping protrusion is provided at the outer end of the telescopic air bag. Anti-slip texture is provided on the flipping protrusion.

[0017] As a further aspect of the present invention: the upper side of the annular loading disk is provided with several drainage grooves at equal angles.

[0018] Compared with the prior art, the beneficial effects of the present invention are: Achieving non-contact deep salt reduction without damaging ingredients: By periodically adjusting the pressure inside the sealed shell through a pressure regulating pump, the pickled vegetables are repeatedly switched between extrusion and expansion states. This non-contact method continuously forces out the high-salt juices from inside the ingredients, effectively reducing salt content and avoiding damage to pickled vegetables caused by traditional extrusion methods, thus ensuring product integrity.

[0019] It combines spraying for pickling and juice replacement functions to achieve salt reduction, freshness preservation, and consistent taste: The combined guide spraying mechanism can periodically spray the pickling liquid or water. On the one hand, it can deeply spray the under-pickled parts to eliminate pickling dead corners; on the other hand, it can use a certain concentration of pickling liquid to replace the juice inside the pickled vegetables, so that the product has uniform saltiness and consistent taste. It completes the freshness treatment while reducing salt, and greatly improves the quality of pickled vegetables.

[0020] The combined flow guiding structure is easy to install, has reliable sealing, and provides uniform spraying: the liquid inlet flow guiding cylinder, multiple combined flow guiding cylinders, and the combined installation platform are quickly positioned by positioning guide columns and positioning guide holes, and a reliable seal is formed by the extrusion sealing ring and the annular sealing groove. Series installation is convenient and quick; after the liquid enters the annular flow guiding cylinder through the combined flow guiding cylinder, it is evenly sprayed from multiple nozzles arranged in a circumferential direction to ensure complete coverage of the pickled vegetables.

[0021] The turning angle can be adjusted as needed to achieve continuous turning in a cycle, avoiding adhesion and dead corners in the processing: The loading mechanism can adjust the initial deflection angle of the telescopic airbag and the turning protrusion according to different ingredients through locking studs and bevel gear transmission; when the air pressure changes periodically, the deflection air cylinder and telescopic airbag drive the turning protrusion to extend and deflect, and the adjacent turning protrusions take turns to turn the pickled vegetables in a cycle, which effectively prevents the pickled vegetables from sticking to the loading tray, ensures that there are no dead corners in the salt reduction and preservation processing, and improves the single processing volume and work efficiency.

[0022] The drainage groove design allows for timely liquid diversion, improving processing efficiency and quality: The drainage grooves on the annular loading tray can promptly collect and drain the juices that seep out during the depressurization osmosis process, as well as the sprayed marinade or water, preventing high-concentration or uneven juices from stagnating and affecting the food, thus further improving the efficiency and quality of salt reduction and preservation.

[0023] Easy to clean and centralized wastewater discharge: After the operation is completed, clean water can be introduced through the combined guide spraying mechanism to spray and clean the inside of the device and the adjusting loading mechanism. Opening the solenoid valve will allow the cleaning wastewater and the previously collected liquid to converge in the liquid collection semi-circular hood and be discharged from the drain pipe in a unified manner, making cleaning and maintenance simple.

[0024] Achieving salt reduction and preservation while ensuring production cycle: The entire device, which cannot avoid the high-salt environment for producing pickled vegetables, significantly improves product quality without extending the production cycle through the synergistic effect of depressurized osmosis and controlled spraying, and has good practicality and promotional value.

Detailed Implementation

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0043] Example 1, please refer to Figures 1-3In this embodiment of the invention, a depressurization osmosis desalination and preservation device for pickled vegetable processing includes a vertically arranged cylindrical mounting shell 1. A liquid inlet guide tube 5 is vertically arranged at the middle of the upper end of the cylindrical mounting shell 1. Several support legs 2 are arranged at equal angles along the lower edge of the cylindrical mounting shell 1. An inlet / outlet port 12 is provided on the cylindrical wall of the cylindrical mounting shell 1, and a sealing gate 3 is rotatably arranged on the inlet / outlet port 12. The device includes: The lower end of the cylindrical mounting housing 1 is provided with a combined mounting platform 13 at the middle position. The combined mounting platform 13 and the liquid inlet guide tube 5 are arranged opposite each other. A liquid collecting semi-circular ring cover 6 is connected between the combined mounting platform 13 and the lower end of the cylindrical mounting housing 1. A liquid drain pipe 7 is provided at the lower end of the liquid collecting semi-circular ring cover 6. A solenoid valve 4 is connected in series on the liquid drain pipe 7. An adjusting conduit 8 is connected to the cylindrical wall of the cylindrical mounting housing 1, and a pressure regulating pump 9 is connected to the adjusting conduit 8. It combines a flow-guiding spraying mechanism and several adjusting loading mechanisms.

[0044] First, several adjusting loading mechanisms and combined flow-guiding spraying mechanisms are assembled and installed, then fixed inside the cylindrical mounting housing 1, connecting it to the liquid inlet guide tube 5. The liquid inlet guide tube 5 is connected to an external liquid supply device, which can provide either pickling liquid or clean water. The pickled vegetables to be processed are placed on the adjusting loading mechanisms, and then the sealing gate 3 is closed. At this time, the solenoid valve 4 is closed, forming a sealed space inside the cylindrical mounting housing 1. The pressure inside the cylindrical mounting housing 1 is periodically adjusted by the pressure regulating pump 9. As the pressure inside the cylindrical mounting housing 1 increases or decreases, the pickled vegetables placed on the adjusting loading mechanisms periodically switch between compression and expansion, continuously forcing out the high-salt juice inside. Non-contact compression and expansion allow the pickled vegetables to extract the deep, high-salt juice without damage. Simultaneously, the combined flow-guiding spraying mechanism periodically sprays pickling liquid or clean water into the cylindrical mounting housing 1. On the one hand, it can deeply spray the under-pickled vegetables, allowing the pickling liquid to reach the inside of the pickled vegetables and eliminate pickling dead corners. On the other hand, it can use a certain concentration of pickling liquid, the concentration of which is adjusted according to the pickled vegetable ingredients and sales region, to replace the internal pickling juice of under-pickled and over-pickled vegetables, so that the taste of the pickled vegetables is uniform and salt reduction and freshness is achieved. After the operation is completed, the sealing gate 3 is opened, the pickled vegetables are taken out, the sealing gate 3 is closed, and clean water is introduced into the combined flow-guiding spraying mechanism to clean the inside of the device. At this time, the solenoid valve 4 is opened, so that the clean water spraying adjustment loading mechanism and the previous wastewater converge in the liquid collection semi-circular ring 6, and finally discharged from the drain pipe 7 by opening the solenoid valve 4. Under the premise that high-salt environments cannot be avoided in the production of pickled vegetables, this device can reduce salt and preserve freshness, thereby significantly improving the quality of pickled vegetables while ensuring the production cycle.

[0045] Example 2, based on Example 1, please refer to... Figures 1-6 and Figure 12 In this embodiment of the invention, the combined flow guiding spraying mechanism includes a plurality of combined flow guiding cylinders 10 connected in series. The two ends of the combined flow guiding cylinders 10 are respectively connected to the liquid inlet flow guiding cylinder 5 and the combined mounting platform 13. The upper half of the cylinder wall of the combined flow guiding cylinder 10 is provided with annular flow guiding cylinders 20. The annular flow guiding cylinders 20 are connected to the inside of the combined flow guiding cylinder 10. The annular flow guiding cylinders 20 extend out of the cylinder wall of the combined flow guiding cylinder 10 and are provided with a plurality of nozzles 21 at equal angles. The upper ends of the combined guide tube 10 and the combined mounting platform 13 are both provided with upper fixing rings 17.

The lower fixing rings 14 on the outer side of the annular sealing grooves 16 are provided with a plurality of combined mounting holes 15 at equal angles. The combined mounting holes 15 on the upper fixing rings 17 and the lower fixing rings 14 are aligned and fixed with external bolts and nuts. The lower fixing rings 14 are provided with positioning guide holes 37 in conjunction with the positioning guide posts 36. By cooperating with the positioning guide post 36 and the positioning guide hole 37, the liquid inlet guide tube 5, the combined guide tube 10 and the combined mounting platform 13 are connected in series. At this time, the combined mounting holes 15 of the upper fixed mounting ring 17 and the lower fixed mounting ring 14 are set facing each other and fixed by external bolts and nuts. At the same time, the compression sealing ring 18 is inserted into the annular sealing groove 16 to ensure the sealing performance after series connection. External industrial equipment introduces clean water or pickling liquid, which is guided into each annular guide tube 20 through the combined guide tube 10 and finally discharged from each nozzle 21 to achieve spraying of pickled vegetables.

[0046] Example 3, based on Example 2, please refer to... Figures 6 to 14 and Figure 1 In this embodiment of the invention, several adjusting loading mechanisms are respectively arranged on the combined guide tube 10; the adjusting loading mechanism includes a rotating mounting sleeve 19 arranged on the outer side of the lower half of the combined guide tube 10, a rotating mounting ring 25 is movably arranged inside the rotating mounting sleeve 19, and an annular loading disk 11 is arranged on the outer side of the rotating mounting ring 25. The annular loading disk 11 can be tilted to enter and exit from the inlet and outlet 12. Several deflection mounting holes 23 are arranged at equal angles on the annular loading disk 11. Each rotating mounting ring 25 opposite to the deflection mounting hole 23 is provided with a limiting rotating hole 26. A pneumatic adjustment module is provided in conjunction with the limiting rotating hole 26 and the deflection mounting hole 23. The rotating mounting ring 25 is symmetrically provided with limiting rotating rings 27 on its upper and lower sides. The inner side of the rotating mounting sleeve 19 is provided with limiting rotating grooves 32 to cooperate with the limiting rotating rings 27. A locking screw cylinder 28 is provided on the rotating mounting ring 25 through the mounting plate. A locking stud 29 is provided in cooperation with the locking screw cylinder 28. The locking screw cylinder 28 and the locking stud 29 are both facing the rotating mounting sleeve 19. The pneumatic adjustment module includes a limiting rotation column 34 that is configured to cooperate with the limiting rotation hole 26. One end of the limiting rotation column 34 is configured with a synchronous bevel gear 31 that is configured to cooperate with the inner side of the rotating mounting sleeve 19. An adjusting bevel gear ring 33 is configured to cooperate with the inner side of the rotating mounting sleeve 19. The adjusting bevel gear ring 33 meshes with the synchronous bevel gear 31. The other end of the limiting rotation column 34 is configured with a synchronous transmission column 39 that is configured to cooperate with the deflection mounting hole 23. A deflection air cylinder 22 is configured on the synchronous transmission column 39 that is configured to cooperate with the deflection mounting hole 23. A telescopic air bag 38 is configured to be connected to the outer side of the deflection air bag 22. A flipping protrusion 30 is configured on the outer end of the telescopic air bag 38. Anti-slip texture 35 is configured on the flipping protrusion 30. The upper side of the annular loading disk 11 is provided with several drainage grooves 24 at equal angles.

[0047] Depending on the type of pickled vegetables, rotate the locking stud 29 to loosen it within the locking cylinder 28. At this point, the locking stud 29 is no longer pressed against the rotating mounting sleeve 19. With the cooperation of the limiting rotating ring 27 and the limiting rotating groove 32, rotate the annular loading disc 11 or the rotating mounting ring 25 to make it rotate a certain angle. During this process, adjust the bevel gear ring 33 and the synchronous bevel gear 31 to mesh synchronously. With the cooperation of the limiting rotating hole 26 and the limiting rotating column 34, the synchronous transmission column 39 deflects a certain angle, thus causing the deflection cylinder 22, the telescopic air bag 38, and the flipping protrusion 30 to deflect a certain angle. The angle is changed by altering the initial deflection angle of the telescopic airbag 38. As the air pressure inside the cylindrical mounting housing 1 increases or decreases periodically, the gas volume inside the deflection air cylinder 22 and the telescopic airbag 38 also increases or decreases accordingly. This causes the flipping protrusion 30 to synchronously shift at the initial angle as the telescopic airbag 38 extends and retracts. Adjacent flipping protrusions 30 take turns to continuously flip the pickled vegetables periodically, preventing them from sticking to the annular loading tray 11. This ensures that the salt reduction and preservation operation is fully carried out, truly achieving no dead angles. Furthermore, while ensuring the salt reduction and preservation effect, it can increase the amount of pickled vegetables processed in one go, thus improving efficiency. The drainage groove 24 on the annular loading tray 11 can promptly collect and drain the juices on the pickled vegetables and the pickling liquid and water sprayed by the nozzle 21 during the depressurization osmosis and salt reduction preservation operation, preventing the high concentration or uneven concentration of juices from affecting the pickled vegetables and improving the efficiency and quality of salt reduction preservation.
