Description

Technical Field

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

[0002] In meat processing, curing is a critical process for enhancing product flavor and extending shelf life. Currently, the industry generally uses fixed curing tanks (tanks) or drum-type curing equipment for batch processing. However, these traditional devices have exposed significant cleaning efficiency and hygiene and safety risks over long-term use, directly impacting production continuity and product quality stability, primarily in the following areas.

[0003] Existing pickling tanks often utilize a one-piece, enclosed structure with numerous concave and convex structures on the interior walls (e.g., weld seams, stirring shaft brackets, etc.). Meat scraps, blood, and high-salt sauces from pickling easily cling to these narrow crevices, creating a breeding ground for microorganisms. Conventional flushing and manual scrubbing are difficult to completely remove these residues. Long-term accumulation not only increases the risk of cross-contamination but also potentially violates food safety regulations through the formation of biofilms.

[0004] Traditional tanks typically feature only a single bottom drain outlet, and the bottom lacks an effective angled design. During cleaning, large amounts of wastewater and debris accumulate in grooves or low-lying areas of the tank pipes, preventing gravity from draining them completely. This residual wastewater becomes a source of odor, easily causing flavor transfer when marinating different flavors of meat, seriously affecting the product's flavor purity. Furthermore, the humid environment inside the tank accelerates corrosion of the equipment, shortening its service life.

[0005] At the same time, in order to complete deep cleaning, the existing equipment must completely stop production and perform multiple steps such as emptying, manual tank cleaning, repeated flushing and disinfection. A single cleaning process often takes several hours, causing frequent interruptions to the continuous production processing line, significantly restricting the overall efficiency of the pickling process.

[0019] The present invention also discloses a meat pickling method, which is applied to the above-mentioned meat pickling device and includes the following specific steps:

[0020] Step 1: When the meat needs to be marinated, multiple double-arc cavity plates are flipped over to be spliced together to form a tank body. After completion, the meat is added to the tank body;

[0021] Step 2: Use the sauce adding component to add sauce into the tank. At the same time, rotate the tank and use the convex structure inside to cooperate with the sauce adding component to knead the meat to achieve marinating of the meat.

[0022] Step 3: After the meat is marinated, the flip drive assembly is used to control the flipping of the multiple double-arc cavity plates. At this time, multiple strip grooves can be formed between the multiple double-arc cavity plates, and the marinated meat can fall quickly from the strip grooves;

[0023] Step 4: After the double-arc cavity plate is flipped 180 degrees, the arc surface with the sauce is flipped to the outside. At this time, the clean other side reconstructs the inner wall of the tank, and the next batch of meat can be quickly marinated. At the same time, the outer wall of the tank formed by the arc surface with the sauce is quickly cleaned using external cleaning equipment.

[0024] The present invention provides a meat pickling device and method through improvements, which have the following improvements and advantages compared with the prior art:

[0025] First, the dual-arc cavity plate of the present invention can be rotated 180°, turning the dirty side with sauce into the outer wall, and the clean side into the inner wall to directly add the next batch of pickling. The outer wall cleaning and internal pickling are carried out simultaneously, reducing a lot of cleaning downtime. In addition, when the cavity plate is turned 90°, a strip groove is formed, and the pickled meat flows directly out by gravity, eliminating manual scooping and significantly improving unloading efficiency. Finally, after the flip, the residual sauce surface is exposed and can be directly sprayed and rinsed without entering the interior of the tank.

[0026] Secondly, the inner wall of the tank, which is composed of a double-arc cavity plate of the present invention, is composed of multiple convex structures. When rotating, it squeezes and kneads the meat, accelerating the penetration of sauce and shortening the marinating time. At the same time, the sauce adding component automatically triggers the hammer rod to beat the meat as the cavity plate rotates, achieving "adding and kneading" synchronization and avoiding the unevenness problem of traditional static soaking.

[0027] Thirdly, when the pushing block of the present invention moves downward, the side passage is blocked, forcing the sauce to be ejected from the liquid outlet at high pressure, thereby avoiding clogging by viscous sauce. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] The present invention provides a meat pickling device and method through improvement. The technical solution of the present invention is:

[0042] Example 1

[0043] like Figures 1 to 9 As shown, an embodiment of the present invention provides a meat marinating device, comprising a base plate 1 and a mounting plate 2, and further comprising:

[0044] The pickling tank assembly includes a plurality of rotating shafts 10, and a double-arc cavity plate 6 is fixed on each rotating shaft 10. The plurality of double-arc cavity plates 6 together constitute a complete tank body, and the inner wall of the tank body has multiple convex structures; the double-arc cavity plate 6 can be turned over, as shown in the attached Figure 1-Figure 3 As shown, at this time, multiple double-arc cavity plates 6 form a complete tank body, which can be used as a meat pickling container; and when the double-arc cavity plate 6 is turned 90 degrees, as shown in the attached Figure 8 As shown, at this time, the double-arc cavity plate 6 forms a strip groove to achieve rapid material discharge. At this time, a receiving tray can be placed on the mounting plate 2 to collect the marinated meat;

[0045] When the double-arc cavity plate 6 continues to flip 90°, the arc surface with the sauce is flipped to the outside, and the clean other side re-constitutes the inner wall of the tank body. At this time, the receiving tray can be removed and the double-arc cavity plate 6 can be cleaned using external cleaning equipment. In summary, the flipping design of the double-arc cavity plate 6 can enable the cleaning of the outer wall of the tank and the pickling operation inside the tank to be carried out simultaneously.

[0046] The flip drive assembly is arranged on one side of the multiple double-arc cavity plates 6, and the flip drive assembly is used to drive the multiple double-arc cavity plates 6 to flip. The flip drive assembly includes a circular end plate 9, and multiple shafts 10 are equidistantly mounted on the circular end plate 9. A transmission gear 11 is fixed to one end of each shaft 10. A hollow gear plate 15 adapted to the transmission gear 11 is rotatably mounted at the center of the circular end plate 9. A worm gear 14 is fixed at the center of the hollow gear plate 15. A self-locking The servo motor 12 is provided, and the output shaft of the self-locking servo motor 12 is fixedly connected to a worm 13 meshing with a worm gear 14. The lead angle of the worm 13 and the worm gear 14 is less than the friction angle. Through the above structure, when the double-arc cavity plate 6 needs to be flipped, the self-locking servo motor 12 can be controlled to start, and the hollow gear plate 15 is driven to rotate by the transmission of the worm 13 and the worm gear 14. The transmission action of the hollow gear plate 15 and the transmission gear 11 drives the rotating shaft 10 to rotate, thereby realizing the flipping of the double-arc cavity plate 6.

[0047] By using the self-locking servo motor 12 and the lead angle of the worm 13 and the worm wheel 14 being smaller than the friction angle, the flipping of the double-arc cavity plate 6 and the flipping before and after can be made more stable, ensuring that the double-arc cavity plate 6 is locked in position after flipping to avoid accidental deployment during operation.

[0048] The sauce adding component includes a sauce adding pipe 16 , on which a plurality of equally distributed top pipes 17 are fixed, and positions of the sauce adding pipe 16 close to the top pipes 17 are each provided with a sauce output mechanism.

[0049] Furthermore, a pair of support ring frames 7 are fixed on the mounting plate 2, and a side ring plate 8 is mounted on one end of a plurality of rotating shafts 10 away from the circular end plate 9 for rotation therewith. The pair of support ring frames 7 and the side ring plates 8 and the circular end plate 9 are rotatably connected through bearings; the support ring frames 7 are provided to cooperate with the side ring plates 8 and the circular end plates 9 to constitute the main structure of the pickling device.

[0050] As a further embodiment of the present invention, Figure 4-Figure 6As shown, a piston rod 171 is slidably installed on the inner wall of each top tube 17, and a return spring 18 is fixed between the piston rod 171 and the top of the top tube 17, and a stop wheel 172 is rotatably installed on the top of each piston rod 171; when the multiple double-arc cavity plates 6 rotate, their arc surfaces can be used to cooperate with the stop wheel 172 to push the piston rod 171 downward.

[0051] Furthermore, the sauce output mechanism includes a bottom cylinder 29 fixed to the bottom side of the sauce adding tube 16, and the bottom cylinder 29 is coaxially arranged with the top tube 17. An extension rod 19 is fixed to the bottom of the piston rod 171, and the extension rod 19 can move through the sauce adding tube 16 and the bottom cylinder 29. The bottom end of the extension rod 19 is fixedly installed with a mounting rod 24; when the piston rod 171 moves downward, it can drive the extension rod 19 and the mounting rod 24 to move downward synchronously.

[0052] Furthermore, a plurality of extension tubes 21 are fixedly installed at the bottom end of the mounting rod 24, and a hammer rod 22 is slidably installed in the extension tube 21, and a connecting spring 23 is fixed between the top end of the hammer rod 22 and the extension tube 21; through the above structure, when the mounting rod 24 moves downward, it can cooperate with the connecting spring 23 and the hammer rod 22 to achieve kneading of the meat and ensure the marinating effect of the meat.

[0053] Furthermore, side passages 20 are fixedly connected between the two sides of the bottom cylinder 29 and the sauce adding tube 16. The bottom end of the bottom cylinder 29 is provided with a liquid outlet end 27 with an integral structure therewith, and the liquid outlet end 27 is provided with evenly distributed liquid outlet holes 28. The end of the bottom cylinder 29 near the top is provided with a plurality of equidistantly distributed air holes 26, and the extension rod 19 is fixedly mounted with a pushing block 25 that is slidably connected to the inner wall of the bottom cylinder 29; by means of the provided side passage 20, the sauce can enter the bottom cylinder 29 from the sauce adding tube 16 and the side passage 20, and at the same time, the pushing block 25 can move downward synchronously with the extension rod 19, and the pushing block 25 can use its outer wall to block the side passage 20. As the pushing 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.

[0054] As a further embodiment of the present invention, Figure 1-Figure 5 As shown, a pair of multi-stage electric telescopic rods 3 are fixed to one end of the top of the mounting plate 2, and the extended ends of the two multi-stage electric telescopic rods 3 are commonly fixedly connected to a transmission sleeve 301, the transmission sleeve 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, the multi-stage electric telescopic rod 3 is set, and it is convenient to use the transmission sleeve 301 to drive the sauce adding pipe 16 to move.

[0055] Furthermore, 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 the driving conical gear 501, and a driven conical gear ring 31 meshing with the driving conical gear 501 is fixedly installed on the circular end plate 9; through the above structure, when the driving motor 5 is controlled to start, the transmission action of the driving conical gear 501 and the driven conical gear ring 31 can be used to drive the circular end plate 9 to rotate, so as to realize the rotational drive of the tank body.

[0056] Furthermore, a pair of mounting blocks 32 are fixed on one side of the top of the base plate 1, and 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 base plate 1 and the mounting plate 2 through a hinge, and a grid frame 30 is fixedly installed between the outer peripheral wall of each rotating shaft 10 and the double-arc cavity plate 6; through the above structure, the hydraulic rod 4 is used to flip the plate 2 with the rotating column 33 as the axis, and the angle of the mounting plate 2 can be adjusted.

[0057] The specific working method is: start the self-locking servo motor 12, use the transmission of the worm 13 and the worm wheel 14 to drive the hollow gear plate 15 to rotate; and then drive the rotating shaft 10 through the transmission effect of the hollow gear plate 15 and the transmission gear 11 to realize the flipping of the double-arc cavity plate 6 and assemble the complete tank body (such as Figure 1 As shown in the figure, meat is added to the tank body. When the drive motor 5 is started, the driving conical gear 501 and the driven conical gear ring 31 drive the circular end plate 9 to rotate, thereby realizing the rotational drive of the tank body and kneading the meat using the convex surface structure of 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 pipe 20. When the tank body rotates, the arc surface of the double-arc cavity plate 6 presses the wheel 172, causing the piston rod 171 to press down and driving the extension rod 19 to move synchronously. Finally, the hammer rod 22 is driven to move downward to beat the meat. The provided connecting spring 23 can buffer the rebound to simulate manual kneading.

[0058] 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 passage 20. The pushing block 25 can move downward synchronously with the extension rod 19. The pushing block 25 can use its outer wall to block the side passage 20. As the pushing block 25 continues to move downward, the sauce at the bottom of the bottom cylinder 29 is accelerated and squeezed out through the liquid outlet 28.

[0059] When the meat needs to be unloaded, the self-locking servo motor 12 is controlled to reverse and drive the double-arc cavity plate 6 to flip 90° to form a strip groove. At this time, the meat pieces can fall from the strip groove; after unloading is completed, the double-arc cavity plate 6 continues to flip to 180°, the sauce residual surface becomes the outer wall, and the clean surface constitutes the inner wall of the new tank; the external spray equipment directly rinses the exposed dirty surface, and at the same time, the new batch of meat can be directly put into marinating.

[0060] Example 2

[0061] The second embodiment provides a meat curing method, which is applied to the meat curing device described in the first embodiment. The method includes the following specific steps:

[0062] Step 1: When the meat needs to be marinated, multiple double-arc cavity plates 6 are turned over to be spliced together to form a tank body. After completion, the meat is added to the tank body;

[0063] Step 2: Use the sauce adding component to add sauce into the tank. At the same time, rotate the tank and use the convex structure inside to cooperate with the sauce adding component to knead the meat to achieve marinating of the meat.

[0064] Step 3: After the meat is marinated, the flip drive assembly is used to control the flipping of the multiple double-arc cavity plates 6. At this time, multiple strip grooves can be formed between the multiple double-arc cavity plates 6, and the marinated meat can fall quickly from the strip grooves;

[0065] Step 4: After the double-arc cavity plate 6 is flipped 180 degrees, the arc surface with the sauce is flipped to the outside. At this time, the clean other side reconstitutes the inner wall of the tank body, and the next batch of meat can be quickly marinated. At the same time, the outer wall of the tank body formed by the arc surface with the sauce is quickly cleaned using external cleaning equipment.
