[0002] Currently, traditional meat curing methods mainly rely on manual operation or simple mechanical soaking, which has problems such as low curing efficiency, uneven brine penetration, and poor meat tenderization effect.

[0003] Conventional marinating equipment typically uses a static soaking method, where brine relies solely on natural diffusion to penetrate the meat products, resulting in a long marinating period and uneven flavor penetration inside and out.

The end of the adjusting slider away from the lower pressing shaft is connected to a connecting shaft, and the connecting shaft is perpendicular to the cylindrical outer wall of the lower pressing shaft and located inside the pressing roller. A connecting sleeve is sleeved on the outside of the connecting shaft, and multiple connecting rods are connected to both ends of the connecting sleeve and connected to the pressing roller through the multiple connecting rods.

[0011] Preferably, the injection assembly includes an injection cylinder, an injection tube, and an injection piston. Multiple injection cylinders are connected to the cylindrical inner wall of the extrusion roller, and all of the multiple injection cylinders are perpendicular to the inner wall of the extrusion roller and located outside the connecting shaft.

[0016] Compared with the prior art, the present invention provides a high-efficiency meat marinating device with adaptive adjustment function, which has the following beneficial effects: 1. This invention adopts a liftable marinating rack structure composed of an upper cover, a connecting frame, and multiple layers of laid mesh plates. The overall lifting is achieved through a hanging ring, a limiting slide bar, and a downward pressing stud, which facilitates the laying of meat products and the sealing of the marinating bucket. At the same time, it ensures that the meat products are evenly soaked in brine, improving marinating efficiency and ease of operation.

[0017] 2. This invention uses a marinating motor to drive a downward rotating shaft, which in turn drives multiple extrusion rollers to roll. Combined with an elastic component, the extrusion rollers can adapt to meat products of different thicknesses, achieving dynamic extrusion and pounding to relax the meat structure and achieve a tenderizing effect. At the same time, the extrusion rollers have built-in injection components that can inject brine into the meat products during the rolling process, accelerating penetration and improving marinating efficiency and uniformity.

[0018] 3. The elastic component of this invention adopts an adjusting slide bar, a compression spring, and an adjusting slider structure, which enables the compression roller to adaptively bounce on the surface of meat products, ensuring a tight fit while avoiding excessive compression that could damage the meat. The support spring and the limiting slip ring, together with the pressing stud, enable the marinating motor to rise and fall smoothly, reducing mechanical wear.

[0019] 4. The injection assembly of this invention automatically completes saline injection and aspiration by cooperating with the injection cylinder, injection tube and injection piston when the squeezing roller rolls. The saline is circulated and replenished by the return spring and negative pressure. The double sealing design of the injection plug head and the aspiration plug head ensures unidirectional flow of saline, avoids backflow and improves injection accuracy and efficiency.

[0020] 5. In this invention, multiple extrusion rollers simultaneously stir the brine in the marinating tank during the rolling process, preventing uneven concentration in certain areas and ensuring that meat products are marinated in a uniform brine, thereby further improving the marinating effect and consistency.

[0021] 6. The pressing stud of this invention uses friction-reducing ball bearings to reduce rotational friction and extend the service life of the components; the insertion design of the adjusting insert and the pressing shaft ensures accurate axial positioning, prevents deviation, and ensures stable pressing and rolling of the extrusion roller.

[0022] 7. The injection sealing spring and the aspiration sealing spring work together to automatically open and close the liquid guide hole during the injection and aspiration stages, preventing saline backflow, ensuring efficient and controllable injection process, and reducing saline waste.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides, for example Figures 1-10 The illustrated high-efficiency meat marinating device with adaptive adjustment function includes a marinating barrel 1. Support legs 2 are connected to the outer lower end of the marinating barrel 1. An upper cover 3 is fitted onto the outer upper end of the marinating barrel 1. Multiple connecting frames 4 are connected to the outer lower end of the upper cover 3, and these connecting frames 4 are located inside the marinating barrel 1 and tightly fitted to its inner wall. Multiple laying mesh plates 5 are connected between the connecting frames 4, and are evenly distributed vertically within the marinating barrel 1. A downward pressing shaft 6 extends vertically through the center of the upper cover 3, with its lower end penetrating the center of the multiple laying mesh plates 5. A marinating motor 7 is connected to the upper end of the downward pressing shaft 6 via a motor shaft, and is located above the upper cover 3. Multiple extrusion rollers 8 are rotatably connected to the outside of the downward pressing shaft 6 via elastic components. These extrusion rollers 8 are circumferentially distributed from top to bottom and are located above the multiple laying mesh plates 5. Each cylindrical outer wall of the multiple extrusion rollers 8 is equipped with a filling device. The injection assembly has multiple limiting slide rods 9 connected to the upper end of the upper cover 3, and all the limiting slide rods 9 are located outside the marinating motor 7. A hanging seat 12 is connected to the upper end of each limiting slide rod 9. A downward pressure stud 13 is threadedly connected to the center of the inner part of the hanging seat 12, and a lifting ring 14 is connected to the center of the upper end of the downward pressure stud 13. During the marinating process of meat, multiple connecting frames 4 and multiple laying mesh plates 5 form a marinating rack. The marinating rack and the marinating barrel 1 are combined to form a marinating device. Because the marinating rack is connected to the upper... The cap 3, the limiting slide bar 9, the lifting seat 12, and the pressing stud 13 are connected to the lifting ring 14, so the marinating rack can be lifted by the lifting ring 14, and the opening at the top of the marinating barrel 1 can be opened at the same time to introduce the marinating brine into the marinating barrel 1. The cut meat products are evenly laid on the top of multiple laying mesh plates 5, and then the marinating rack is lifted into the marinating barrel 1 again. The top of the marinating barrel 1 is sealed by the upper cap 3, so that the meat products are marinated in the brine in a sealed environment.

[0036] During the marinating process of the meat products, the marinating motor 7 is activated. The marinating motor 7 drives multiple extrusion rollers 8 to roll on the upper part of the meat products through the downward pressing shaft 6 and the elastic component. The extrusion rollers 8 can adaptively fit the upper part of meat products of different thicknesses through the elastic component, allowing the extrusion rollers 8 to bounce between meat products of different thicknesses. This allows the extrusion rollers 8 to squeeze and pound the meat products, loosening the meat structure and achieving a tenderizing effect. At the same time, the multiple extrusion rollers 8 can inject brine into the meat products through the injection component, accelerating the efficiency of brine penetration into the meat products, allowing the meat products to fully absorb the brine, improving the marinating efficiency and effect. In addition, the multiple extrusion rollers 8 stir inside the marinating tank 1, making the brine concentration inside the marinating tank 1 more uniform, further improving the marinating effect.

[0037] like Figures 1-5 As shown, a limiting slip ring 10 is connected to the outer side of the lower end of the pickling motor 7, and multiple limiting slide rods 9 pass through the inside of the limiting slip ring 10 and are slidably connected to the limiting slip ring 10. Multiple support springs 11 are provided at the lower end of the limiting slip ring 10, and the multiple support springs 11 are respectively sleeved on the outside of the multiple limiting slide rods 9. Multiple resistance-reducing ball bearings 15 are provided inside the outer side of the lower end of the pressing stud 13. An adjusting insert 16 is connected to the center of the lower end of the pickling barrel 1, and the lower end of the pressing shaft 6 is inserted into the adjusting insert 16. When the pickling rack is lifted from inside the pickling barrel 1, the pressing stud 13 is turned upwards, and the pickling motor 7 is connected to the limiting slip ring 10 and multiple... Under the action of the limiting slide bar 9, it moves upward and drives multiple extrusion rollers 8 to the uppermost side of multiple laying mesh plates 5 through the pressing shaft 6 and the elastic component. This prevents the multiple extrusion rollers 8 from obstructing the laying of meat products and ensures that the meat products can be smoothly laid on the upper end of the multiple laying mesh plates 5. When the marinating rack is hoisted into the marinating barrel 1 again, the pressing stud 13 is turned downward to press down the marinating motor 7. The marinating motor 7 moves downward under the pressure of the pressing stud 13 and drives multiple extrusion rollers 8 to move downward through the pressing shaft 6 and the elastic component, so that the multiple extrusion rollers 8 press on the upper end of the meat products on the upper end of the multiple laying mesh plates 5.

[0038] During the downward turning process, the pressing stud 13 can roll on the upper end of the marinating motor 7 through multiple resistance-reducing balls 15, and press down on the marinating motor 7 through the multiple resistance-reducing balls 15, reducing the wear between the pressing stud 13 and the marinating motor 7, avoiding damage to the marinating motor 7 and the pressing stud 13, and reducing the rotational resistance of the pressing stud 13. In addition, the adjusting insert 16 slides downward inside the multiple laying mesh plates 5, and the position inside the marinating barrel 1 is adjusted by inserting the adjusting insert 16, ensuring that the pressing shaft 6 can move down smoothly.

[0039] As shown in the figure, press down on the rotating shaft 6 and Figure 7As shown, the elastic component includes an adjusting slide bar 18, a compression spring 19, and an adjusting slider 20. Multiple adjusting grooves 17 are formed on the cylindrical outer wall of the pressing shaft 6, and these grooves are distributed circumferentially from top to bottom. Two adjusting slide bars 18 are connected between the inner walls of the upper and lower ends of each adjusting groove 17. An adjusting slider 20 is slidably connected inside each adjusting groove 17. Two compression springs 19 are provided at the upper end of the adjusting slider 20, and each compression spring 19 is sleeved outside the two adjusting slide bars 18. A connecting shaft 21 is connected to the end of the adjusting slider 20 away from the pressing shaft 6. The connecting shaft 21 is perpendicular to the cylindrical outer wall of the pressing shaft 6 and located inside the compression roller 8. A connecting sleeve 22 is sleeved outside the connecting shaft 21. Multiple connecting rods 23 are connected to both ends of the 22 externally, and are connected to the extrusion roller 8 through the multiple connecting rods 23. When the extrusion roller 8 rolls on the upper end of the meat product, the adjustment groove 17 restricts the position of the adjustment slider 20 and the connecting shaft 21 through the adjustment rod 18. The connecting shaft 21 is rotatably connected to the extrusion roller 8 through the connecting sleeve 22 and the connecting rod 23, so that the pressing shaft 6 can drive the extrusion roller 8 to rotate through the elastic component. At the same time, the extrusion roller 8 can adjust its position by sliding up and down inside the adjustment groove 17 through the adjustment slider 20, so that the extrusion roller 8 can roll on the upper end of meat products of different thicknesses. The extrusion roller 8 can be tightly pressed against the meat product by the elastic pressing of the extrusion spring 19 and bounce between meat products of different thicknesses.

[0040] like Figure 8 and Figure 9As shown, the injection assembly includes an injection cylinder 24, an injection tube 27, and an injection piston 28. Multiple injection cylinders 24 are connected to the cylindrical inner wall of the extrusion roller 8, and all injection cylinders 24 are perpendicular to the inner wall of the extrusion roller 8 and located outside the connecting shaft 21. Each injection cylinder 24 has an opening near the connecting shaft 21, and each injection cylinder 24 has a telescopic hole 25 connected to the end away from the connecting shaft 21. The telescopic holes 25 are all located on the cylindrical outer wall of the extrusion roller 8. A limit bracket 26 is connected to the inner wall of the injection cylinder 24 away from the telescopic hole 25. An injection tube 27 is connected to the center of the limit bracket 26 near the telescopic hole 25, and the injection tube 27 passes through the telescopic hole 25 and extends to the outside of the extrusion roller 8. An injection piston 28 is slidably connected inside the injection cylinder 24 near the telescopic hole 25. The injection piston 28 passes through the telescopic hole 25 and is sleeved on the outside of the injection tube 27. The injection tube 27 and the injection piston 28 are flush with the end away from the connecting shaft 21. A return spring 29 is provided between the injection piston 28 and the limiting bracket 26. The return spring 29 is sleeved on the outside of the injection tube 27. During the brine injection of meat products, the end of the injection tube 27 located outside the extrusion roller 8 is provided with a cutting head. Since the injection tube 27 and the injection piston 28 are flush with the end away from the connecting shaft 21, the injection piston 28 protrudes outside the extrusion roller 8. When the outer wall of the extrusion roller 8 rotates to contact the meat products, the injection piston 28 retracts into the injection cylinder 24 and the telescopic hole 25 under the pressure of the extrusion roller 8 and the pushing of the outer wall of the meat products. At the same time, the injection tube 27 is pressed down by the extrusion roller 8 and penetrates into the meat products through the cutting head.

[0041] At this time, the injection piston 28 retracts into the injection cylinder 24. Since the injection piston 28 is in close contact with the inner walls of the injection cylinder 24, the telescopic hole 25, and the injection tube 27, the injection piston 28 will compress the internal space of the injection cylinder 24 and squeeze out the brine inside the injection cylinder 24. This allows the brine to be introduced into the injection tube 27 through the opening at the end near the limiting bracket 26, and injected into the meat product through the opening at the end away from the limiting bracket 26. This injects the brine inside the injection cylinder 24 into the meat product, accelerating the efficiency of brine penetration into the meat product. When the outer wall of the extrusion roller 8 rotates to separate from the meat product, the injection piston 28 pops out again under the action of the return spring 29, increasing the internal space of the injection cylinder 24 and creating a negative pressure inside the injection cylinder 24. This allows the external brine to be drawn into the injection cylinder 24 through the opening at the end near the connecting shaft 21, ready for the next injection.

[0042] like Figure 10As shown, an injection plugging head 30 is slidably connected inside the syringe 24 near the connecting shaft 21. A liquid guide hole is provided on the outer side of the injection plugging head 30 away from the connecting shaft 21, sealing the opening of the syringe 24. An injection plugging spring 31 is provided between the injection plugging head 30 and the limiting bracket 26. A suction plugging head 32 is slidably connected inside the syringe tube 27 near the limiting bracket 26. A liquid guide hole is provided on the outer side of the suction plugging head 32 away from the limiting bracket 26, sealing the opening of the syringe tube 27. A suction plugging spring 33 is provided on the outer side of the suction plugging head 32 away from the limiting bracket 26. A spring support frame 34 is provided on the outer side of the suction plugging spring 33 away from the suction plugging head 32, and the spring support frame 34 is connected to the inner side of the syringe tube 27. On the wall, during the extension and retraction of the injection piston 28, when the injection piston 28 retracts into the injection cylinder 24 and the telescopic hole 25, the pressure of the brine inside the injection cylinder 24 increases. Under the pressure of the injection sealing spring 31 and the brine, the injection sealing head 30 tightly seals the opening of the injection cylinder 24 near the connecting shaft 21, preventing the brine inside the injection cylinder 24 from being squeezed out of the opening. At the same time, the brine inside the injection cylinder 24 overcomes the elastic force of the suction sealing spring 33 and pushes the suction sealing head 32 out of the opening of the injection tube 27 near the limiting bracket 26, and enters the injection tube 27 through the liquid guide hole, so that the brine inside the injection cylinder 24 can only be discharged out through the injection tube 27, ensuring that the injection tube 27 can smoothly inject brine into the meat products.

[0043] Furthermore, when the injection piston 28 pops out again, a negative pressure is generated inside the injection cylinder 24. Under the action of the suction sealing spring 33 and the negative pressure, the suction sealing head 32 tightly seals the opening of the injection tube 27 near the limiting bracket 26, preventing the brine injected into the meat product from being sucked out. At the same time, the negative pressure inside the injection cylinder 24 overcomes the elastic force of the injection sealing spring 31, drawing the injection sealing head 30 into the injection cylinder 24. The brine outside the injection cylinder 24 is then drawn into the injection cylinder 24 through the liquid guide hole, allowing the injection cylinder 24 to be refilled with brine, ensuring sufficient brine for the next injection.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
