Description

Technical Field

[0001] The present invention relates to the technical field of meat marinating, and particularly to a meat marinating device and method thereof. Background Art

[0002] In the field of meat processing, marinating is a key process to enhance product flavor and extend shelf life. Currently, fixed marinating tanks (pools) or drum-type marinating equipment are commonly used in the industry for batch processing. However, such traditional devices have exposed significant cleaning efficiency and hygiene and safety hazards during long-term use, directly affecting production continuity and product quality stability, mainly reflected in the following aspects.

[0003] Existing marinating tanks mostly adopt an integral closed structure, and there are a large number of concave and convex structures on the inner wall (such as welding seams, stirring shaft brackets, etc.). Residual meat scraps, blood and high-salt sauces are easily attached to these narrow gaps, becoming a breeding ground for microorganisms. Conventional rinsing and manual brushing are difficult to completely remove the residues. Long-term accumulation not only increases the risk of cross-contamination, but may also violate food safety regulations due to the formation of biofilms.

[0004] Traditional tanks usually only have a single bottom drain, and the tank bottom lacks an effective inclination design. During cleaning, a large amount of sewage and residues remain in the tank bottom grooves or low-lying areas of the pipes and cannot be completely drained by gravity. The residual sewage becomes an odor source and is extremely likely to cause flavor mixing when marinating different flavored meats subsequently, seriously affecting the purity of the product flavor. At the same time, the humid environment inside the tank accelerates equipment corrosion and shortens the service life.

[0005] At the same time, to complete deep cleaning, existing equipment must completely stop production operation and perform multiple steps such as emptying, manual entry into the tank for brushing, repeated flushing and disinfection; the single cleaning often takes several hours, causing frequent interruptions to the continuous production processing line and significantly restricting the overall efficiency of the marinating link.

When rotating, it exerts extrusion and kneading effects on the meat, accelerating the penetration of the sauce and shortening the marinating time. At the same time, the sauce adding component automatically triggers the hammer rod to pound the meat material as the cavity plate rotates, realizing the synchronization of "feeding - kneading", and avoiding the uneven problem of traditional static soaking. Third: When the pushing block moves downward in the present invention, it blocks the side through pipe, forcing the sauce to be sprayed under high pressure from the liquid outlet hole, avoiding the blockage of viscous sauce.

[0021] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a meat marinating device and method by improvement. The technical solution of the present invention is as follows: Embodiment 1 As Figures 1 to 9 shown, the embodiment of the present invention provides a meat marinating device, including a substrate 1 and a mounting plate 2, and further including: A marinating tank assembly. The marinating tank assembly includes a plurality of rotating shafts 10, and a double-arc surface cavity plate 6 is fixed on each rotating shaft 10. The plurality of double-arc surface cavity plates 6 together form a complete tank body, and the inner wall of the tank body has a plurality of convex surface structures; the provided double-arc surface cavity plate 6 can be flipped. As shown in the appendix, at this time, the plurality of double-arc surface cavity plates 6 form a complete tank body and can be used as a marinating container for meat; when the double-arc surface cavity plate 6 is flipped by 90°, then as shown in the appendix, at this time, the double-arc surface cavity plate 6 forms a strip-shaped groove to achieve rapid blanking. At this time, a receiving tray can be placed on the mounting plate 2 to collect the marinated meat. Figures 1 - 3 shown, Figure 8 shown, at this time, the double-arc surface cavity plate 6 forms a strip-shaped groove to achieve rapid blanking. At this time, a receiving tray can be placed on the mounting plate 2 to collect the marinated meat. When the double-arc surface cavity plate 6 is further flipped by 90°, the arc surface with sauce adheres to the outside, and the clean other side reconstitutes the inner wall of the tank body. At this time, the receiving tray can be removed, and the double-arc surface cavity plate 6 can be cleaned by using an external cleaning device; in summary, by using the flipping design of the double-arc surface cavity plate 6, the cleaning of the outer wall of the tank and the marinating operation inside the tank can be carried out synchronously.

[0023] The flipping drive assembly is arranged on one side of a plurality of double-arc surface cavity plates 6, and the flipping drive assembly is used to drive the plurality of double-arc surface cavity plates 6 to flip. The flipping drive assembly includes a round end plate 9, and a plurality of rotating shafts 10 are rotatably installed on the round end plate 9 at equal distances. A transmission gear 11 is fixed to one end of each rotating shaft 10. A hollow gear disc 15 adapted to the transmission gear 11 is rotatably installed at the center of the round end plate 9. A worm gear 14 is fixed at the center of the hollow gear disc 15. A self-locking servo motor 12 is fixed on one side of the round end plate 9, and a worm 13 meshing with the worm gear 14 is fixedly connected to the output shaft of the self-locking servo motor 12. The lead angles of the worm 13 and the worm gear 14 are less than the friction angle. Through the above structure, when it is necessary to flip the double-arc surface cavity plate 6, the self-locking servo motor 12 can be controlled to start, and the hollow gear disc 15 can be driven to rotate by the transmission of the worm 13 and the worm gear 14; and then through the transmission of the hollow gear disc 15 and the transmission gear 11, the rotating shaft 10 is driven to rotate to realize the flipping of the double-arc surface cavity plate 6. By using the provided self-locking servo motor 12 and the fact that the lead angles of the worm 13 and the worm gear 14 are less than the friction angle, the flipping of the double-arc surface cavity plate 6 and the position before and after flipping can be made more stable, ensuring that the double-arc surface cavity plate 6 is locked in position after flipping and avoiding accidental unfolding during operation.

[0024] The sauce adding assembly includes a sauce adding pipe 16. A plurality of top pipes 17 are fixed on the sauce adding pipe 16 at equal distances, and a sauce output mechanism is provided at a position on the sauce adding pipe 16 close to the top pipes 17.

[0025] Furthermore, a pair of support ring frames 7 are fixed on the mounting plate 2. The ends of the plurality of rotating shafts 10 away from the round end plate 9 are jointly rotatably installed with a side ring plate 8. The pair of support ring frames 7, the side ring plate 8 and the round end plate 9 are rotatably connected through bearings. The provided support ring frames 7 are used to cooperate with the side ring plate 8 and the round end plate 9 to form the main structure of the pickling device.

[0026] As a further solution of the present invention, as Figures 4 - 6 shown, a piston rod 171 is slidably installed on the inner wall of each top pipe 17, and a return spring 18 is fixed between the piston rod 171 and the top of the top pipe 17. A pressing wheel 172 is rotatably installed at the top of each piston rod 171; when the plurality of double-arc surface cavity plates 6 rotate, their arc surfaces can be used to cooperate with the pressing wheels 172 to push the piston rods 171 to move downward.

[0027] Further, the sauce output mechanism includes a bottom cylinder 29 fixed to the bottom side of the sauce adding pipe 16, and the bottom cylinder 29 is coaxially arranged with the top pipe 17. An extension rod 19 is fixed to the bottom of the piston rod 171, and the extension rod 19 movably penetrates through the sauce adding pipe 16 and the bottom cylinder 29. An installation rod 24 is fixedly installed at the bottom end of the extension rod 19. When the piston rod 171 moves downward, it can drive the extension rod 19 and the installation rod 24 to move downward synchronously.

[0028] Further, a plurality of extension cylinders 21 are fixedly installed at the bottom ends of the installation rods 24, and a hammer rod 22 is slidably installed in each extension cylinder 21. A connecting spring 23 is fixed between the top end of the hammer rod 22 and the extension cylinder 21. Through the above structure, when the installation rod 24 moves downward, it can cooperate with the connecting spring 23 and the hammer rod 22 to knead the meat and ensure the marinating effect of the meat.

[0029] Further, side connection pipes 20 are fixedly connected between both sides of the bottom cylinder 29 and the sauce adding pipe 16. A liquid outlet end 27 integrated with the bottom cylinder 29 is arranged at the bottom end of the bottom cylinder 29, and liquid outlet holes 28 evenly distributed are formed in the liquid outlet end 27. A plurality of air holes 26 are arranged at equal intervals near the top end of the bottom cylinder 29. A pressing block 25 slidably connected to the inner wall of the bottom cylinder 29 is fixedly installed on the extension rod 19. By using the arranged side connection pipes 20, the sauce can enter the bottom cylinder 29 from the sauce adding pipe 16 and the side connection pipes 20. At the same time, the pressing block 25 can move downward synchronously with the extension rod 19, and the pressing block 25 can block the side connection pipes 20 with its outer wall. As the pressing block 25 continues to move downward, the sauce at the bottom of the bottom cylinder 29 is accelerated to be extruded through the liquid outlet holes 28.

[0030] As a further solution of the present invention, as Figures 1 - 5 shown, a pair of multi-stage electric telescopic rods 3 are fixed to one end of the top of the mounting plate 2, and a transmission sleeve frame 301 is fixedly connected to the extending ends of the two multi-stage electric telescopic rods 3. The transmission sleeve frame 301 is fixedly connected to the outer wall of the sauce adding pipe 16. One end of the sauce adding pipe 16 is fixedly connected to a corrugated hose 161, and the corrugated hose 161 is connected to an external sauce supply device. Through the above structure, by using the arranged multi-stage electric telescopic rods 3, it is convenient to drive the sauce adding pipe 16 to move by using the transmission sleeve frame 301.

[0031] Further, a vertical plate is fixedly installed on one side of the top of the mounting plate 2, and a driving motor 5 is fixed on one side of the vertical plate. The output shaft of the driving motor 5 is fixedly connected to a driving bevel gear 501, and a driven bevel gear ring 31 meshing with the driving bevel gear 501 is fixedly installed on the round end plate 9. Through the above structure, when the driving motor 5 is controlled to start, the round end plate 9 can be driven to rotate through the transmission of the driving bevel gear 501 and the driven bevel gear ring 31 to realize the rotational drive of the tank body.

[0032] Further, a pair of mounting blocks 32 are fixed on one side of the top of the substrate 1. A rotating column 33 is fixedly installed between the pair of mounting blocks 32. A connecting seat 34 is fixedly installed on one side of the bottom of the mounting plate 2, and the connecting seat 34 is rotatably connected to the rotating column 33. A pair of hydraulic rods 4 are connected between the substrate 1 and the mounting plate 2 by hinges. A grille frame 30 is fixedly installed between the outer peripheral wall of each rotating shaft 10 and the double-arc surface cavity plate 6; through the above structure, by using the provided hydraulic rod 4, it can be flipped with the rotating column 33 as the axis, and the angle of the mounting plate 2 can be adjusted.

[0033] The specific working method is as follows: By starting the self-locking servo motor 12, using the transmission of the worm 13 and the worm gear 14, the hollow gear disk 15 is driven to rotate; and then through the transmission of the hollow gear disk 15 and the transmission gear 11, the rotating shaft 10 is driven to rotate, so as to realize the flipping of the double-arc surface cavity plate 6 and assemble into a complete tank body (as Figure 1 shown), add meat into the tank body. When controlling the start of the drive motor 5, through the transmission of the drive bevel gear 501 and the driven bevel gear ring 31, the round end plate 9 can be driven to rotate, so as to realize the rotational drive of the tank body and knead the meat by the convex surface structure on its inner wall; at the same time, the external sauce is input into the sauce adding pipe 16 through the corrugated hose 161, and enters the bottom cylinder 29 through the side through pipe 20. When the tank body rotates, the arc surface of the double-arc surface cavity plate 6 presses against the abutting wheel 172, so that the piston rod 171 presses down, and drives the extension rod 19 to move synchronously, and finally drives the hammer rod 22 to move down to hammer the meat block. The provided connecting spring 23 can buffer and rebound to simulate manual kneading; When adding sauce, the sauce enters the sauce adding pipe 16 from the corrugated hose 161 and flows into the bottom cylinder 29 through the side through pipe 20. The push block 25 can move downward synchronously with the extension rod 19. The push block 25 can block the side through pipe 20 with its outer wall. As the push block 25 continues to move downward, the sauce at the bottom of the bottom cylinder 29 is accelerated to be squeezed out through the liquid outlet hole 28; When it is necessary to unload the meat, control the self-locking servo motor 12 to reverse, drive the double-arc surface cavity plate 6 to flip 90°, so as to form a strip-shaped groove. At this time, the meat block can fall from the strip-shaped groove; after unloading is completed, the double-arc surface cavity plate 6 continues to flip to 180°, the sauce residue surface turns to the outer wall, and the clean surface constitutes the inner wall of the new tank body; the external spraying device directly rinses the exposed dirty surface, and at the same time, the new batch of meat materials can be directly put into pickling.

[0034] Embodiment Two This Embodiment Two provides a method for pickling meat. This method is applied to the meat pickling device described in Embodiment One. This method includes the following specific steps: Step One: When it is necessary to pickle meat, multiple double-arc surface cavity plates 6 are flipped to a state of being spliced with each other and form a tank body. After completion, add meat into the tank body; Step 2: Use the set sauce adding component to add sauce into the tank. At the same time, rotate the tank, and use the internal convex structure to cooperate with the sauce adding component to knead the meat, so as to achieve the marinating of the meat; Step 3: After the meat marinating is completed, use the set flipping drive component to control the flipping of multiple double-arc surface cavity plates 6. At this time, multiple strip-shaped grooves can be formed between the multiple double-arc surface cavity plates 6, and the marinated meat can quickly fall from the strip-shaped grooves; Step 4: When the double-arc surface cavity plate 6 is flipped 180 degrees, the arc surface with sauce adheres to the outside, and at this time, the clean other side reconstitutes the inner wall of the tank. Furthermore, the next batch of meat marinating can be quickly carried out. At the same time, the outer wall of the tank formed by the arc surface with sauce adhered can be quickly cleaned by using an external cleaning device.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.

On the outer peripheral wall of each rotating shaft (10) and the double-arc surface cavity plate (6), a grid frame (30) is fixedly installed.

10. A method for marinating meat, which is applied to the meat marinating device according to any one of claims 1-9, and is characterized in that: This method includes the following specific steps: Step 1: When meat needs to be marinated, a plurality of double-arc surface cavity plates (6) are flipped to a state of being spliced with each other to form a tank body. After completion, the meat is added into the tank body. Step 2: Use the provided sauce adding component to add sauce into the tank body. At the same time, rotate the tank body, and use the convex surface structure inside to cooperate with the sauce adding component to knead the meat to achieve the marinating of the meat. Step 3: After the meat marinating is completed, use the provided flipping driving component to control the flipping of a plurality of double-arc surface cavity plates (6). At this time, a plurality of strip-shaped grooves can be formed between the plurality of double-arc surface cavity plates (6), and the marinated meat can quickly fall from the strip-shaped grooves. Step 4: When the double-arc surface cavity plates (6) are flipped 180 degrees, the arc surface with sauce adheres to the outside. At this time, the clean other side reconstitutes the inner wall of the tank body, and thus the next batch of meat marinating can be quickly carried out. At the same time, the outer wall of the tank body formed by the arc surface with sauce adheres to can be quickly cleaned by an external cleaning device.
