Description

Technical Field

[0001] This invention belongs to the field of pork processing technology, specifically a low-temperature slow-curing equipment for pork and its working method. Background Technology

[0002] Low-temperature slow marinating of pork is a key step in the deep processing of meat products. Its purpose is to allow the marinade (such as salt and spices) to slowly and evenly penetrate into the meat, thereby improving the product's flavor, tenderness, and water retention.

[0003] However, existing low-temperature curing equipment and methods generally have some problems:

[0004] First, loading and unloading operations are inconvenient and inefficient. Traditional tumbling machines or marinating tanks are mostly integral structures with small openings. When workers are loading large pieces of pork or taking out finished marinated products, the operating space is limited, which is not only time-consuming and laborious, but also easily causes damage to the meat pieces, affecting the product appearance.

[0005] Secondly, the marinating uniformity is insufficient. In static or simple turning marinating, the pork does not come into sufficient contact with the marinade. In particular, when the marinade contains insoluble solid spices, these spices tend to settle at the bottom of the container, resulting in uneven marinating of the upper and lower layers of meat, which affects the uniformity of product quality.

[0006] Third, the efficiency of marinating needs to be improved. The traditional slow marinating process mainly relies on natural penetration under the concentration gradient, which is a long process. Although there are tumbling machines that accelerate marinating by physically tumbling, the tumbling method is too violent for high-end products that need to maintain the integrity of meat fibers. Summary of the Invention

[0007] The purpose of this invention is to provide a low-temperature slow-curing device for pork and its working method, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a low-temperature slow marinating device for pork and its working method, comprising a storage cylinder and an injection end disposed at the top of the storage cylinder, the storage cylinder comprising a bottom half-cylinder and a top half-cylinder, a sealing mechanism being provided between the top half-cylinder and the bottom half-cylinder, a lifting support being fixedly provided at the end of the bottom half-cylinder, a loading assembly being provided inside the bottom half-cylinder, a rotating shaft being fixedly connected to both ends of the loading assembly, the rotating shaft being rotatably sleeved with the bottom half-cylinder, a drive motor being provided at one end of the bottom half-cylinder, the drive motor controlling the rotation of the loading assembly, actuating plates being symmetrically provided below both sides of the loading assembly, and the loading assembly being eccentrically disposed inside the top half-cylinder and the bottom half-cylinder;

[0009] The loading assembly includes a bottom frame, a top frame, and a slot, wherein the bottom frame and the top frame are detachably installed as a whole through a connecting mechanism.

[0010] Preferably, the injection end includes an injection hole and a sealing plug, the injection hole being opened at the top of the top half-cylinder, and the sealing plug being sleeved in the injection hole.

[0011] Preferably, the sealing mechanism includes a top sealing frame, a bottom sealing frame, and a sealing strip. The top sealing frame is fixed to the outer side of the bottom of the top half-cylinder, the bottom sealing frame is fixed to the outer side of the top of the bottom half-cylinder, the top of the bottom sealing frame is provided with a sealing groove, and the sealing strip is fixed to the top of the top sealing frame and is adapted to the sealing groove.

[0012] Preferably, the lifting support includes a support plate, a crank arm, and an electric push rod. The support plate is fixed to the end of the bottom half-cylinder, the electric push rod is fixed to the top of the support plate, one end of the crank arm is connected to the free end of the electric push rod, and the other end of the crank arm is fixedly connected to the top sealing frame.

[0013] Preferably, the slots are arrayed on the bottom frame and the top frame respectively. The connecting mechanism includes a first fixing plate, a second fixing plate, a fixing rod and a locking cap. The first fixing plate and the second fixing plate are fixed to the sides of the bottom frame and the top frame respectively. The fixing rod is fixed to the top of the first fixing plate and movably connected to the second fixing plate. The locking cap is threaded onto the outside of the fixing rod.

[0014] Preferably, a connecting rod is fixedly connected to the bottom of the bottom frame, and the connecting rod is fixedly connected to the toggle plate.

[0015] Preferably, the rotating shaft has an inner hole and an inner cavity respectively, the inner hole and the inner cavity are connected, the bottom of the rotating shaft is provided with a connected suction and discharge mechanism, and the outside of the bottom half cylinder is provided with a suction and distribution assembly, the suction and distribution assembly is connected to the inner hole.

[0016] Preferably, the suction and discharge mechanism includes a curved tube, a movable plug, a fixed ring, and a spring. The curved tube is fixedly connected to the bottom of the rotating shaft and communicates with the inner cavity. The movable plug is movably sleeved in the curved tube. The fixed ring is fixedly sleeved in the curved tube. The spring is fixedly connected between the movable plug and the fixed ring.

[0017] Preferably, the suction and distribution assembly includes a negative pressure pump, a distribution sleeve, a first hole, and a second hole. The suction end of the negative pressure pump is connected to the distribution sleeve. The distribution sleeve is sleeved on the end of the rotating shaft. The first hole and the second hole are both opened on the distribution sleeve. The first hole and the second hole are connected to the inner hole and are both located on the rotation path of the inner hole.

[0018] A method for operating a low-temperature slow-marinating equipment for pork includes the following steps:

[0019] Step 1: Activate the lifting support unit to move the top half-cylinder upward and separate it from the bottom half-cylinder. Open the bottom half-cylinder, deflect the loading component and keep it horizontal. Arrange the pork pieces to be processed in the bottom loading frame, cover the top loading frame, and assemble and fix it through the connecting mechanism. Reset the top half-cylinder so that the top half-cylinder and the bottom half-cylinder are sealed by the sealing mechanism.

[0020] Step 2: Open the injection end, pour in the marinade and submerge the pork, seal the injection end, start the drive motor, drive the loading component to rotate through the rotating shaft, and make the meat pieces rotate slowly in the marinade to complete the slow marinating.

[0021] Step 3: During rotation, the loading component drives the two side actuating plates to rotate, and when it rotates to the bottom, it agitates the liquid, causing the liquid to swirl.

[0022] Step 4: When rotating slowly, start the suction and distribution component. When the suction and discharge mechanism rotates to the bottom, the suction and distribution component draws in the air inside the suction and discharge mechanism, causing the suction and discharge mechanism to draw in the liquid. When the suction and discharge mechanism rotates to the top of the liquid surface, the air pressure inside the suction and discharge mechanism is restored, and the sucked liquid is sprayed out in the opposite direction.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention provides operators with a spacious and unobstructed operating space through an innovative top semi-cylinder electric lifting and opening structure, making the stacking and removal of large pieces of pork easy and quick, reducing labor intensity, and avoiding meat damage that may occur in traditional small-opening equipment, thus ensuring product quality.

[0025] 2. This invention combines three methods—eccentric rotation, bottom plate disturbance, and top automatic spraying—to create a three-dimensional, dynamic marinating environment. This effectively solves the problems of solid marinade sedimentation and uneven marinade concentration, ensuring that every piece of pork is marinated evenly and significantly improving the consistency of the final product quality.

[0026] 3. This invention uses an automatic suction and spray system to gently accelerate the penetration of the marinade through internal circulation and dynamic spraying of the liquid without resorting to violent pounding. This "slow marinating enhancement" technology not only shortens the marinating cycle but also maximizes the protection of the pork's muscle fiber tissue, resulting in a more tender and juicy finished product.

[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] like Figures 1 to 6 As shown, this embodiment of the invention provides a low-temperature slow-marinating device for pork and its working method, including a storage cylinder and an injection end 3 disposed at the top of the storage cylinder. The storage cylinder includes a bottom half-cylinder 1 and a top half-cylinder 2, with a sealing mechanism 4 between the top half-cylinder 2 and the bottom half-cylinder 1. A lifting support part 5 is fixedly disposed at the end of the bottom half-cylinder 1. A loading assembly 7 is disposed inside the bottom half-cylinder 1. Rotating shafts 8 are fixedly connected to both ends of the loading assembly 7. The rotating shafts 8 are rotatably sleeved with the bottom half-cylinder 1. A drive motor 6 is disposed at one end of the bottom half-cylinder 1. The drive motor 6 controls the rotation of the loading assembly 7. Actuating plates 9 are symmetrically disposed below both sides of the loading assembly 7. The loading assembly 7 is eccentrically disposed inside the top half-cylinder 2 and the bottom half-cylinder 1. The loading assembly 7 includes a bottom frame 71, a top frame 72, and a slot 73. The bottom frame 71 and the top frame 72 are detachably installed as a whole through a connecting mechanism.

[0036] Example: The lifting support units 5 on both sides of the equipment are activated. The electric push rod 53 inside the unit actuates, smoothly lifting the top half-cylinder 2 upwards via the curved arm 52, separating it from the bottom half-cylinder 1. This fully opens the bottom half-cylinder 1, which functions as a marinating chamber. The loading assembly 7 is rotated to a horizontal position, and the detachable top frame 72 is opened. The pork pieces to be processed are neatly stacked on the bottom frame 71, and then the top frame 72 is replaced and locked in place by the connecting mechanism. After loading is complete, the lifting support units 5 are activated in reverse, causing the top half-cylinder 2 to descend. The sealing mechanism 4 at its bottom precisely aligns with the bottom half-cylinder 1 to form a reliable seal. Then, the injection end 3 at the top of the storage cylinder is opened, and the pre-prepared marinating liquid is injected into the cylinder until the liquid level covers the pork in the loading assembly 7. The injection end 3 is then resealed, and the drive motor 6 is started. The motor drives the loading assembly 7 to slowly rotate eccentrically in the marinating liquid via the rotating shaft 8. During the rotation, the equipment simultaneously performs the following actions:

[0037] Turning and agitation: The pork chunks are tumbled three-dimensionally in the liquid as the eccentrically rotating loading component 7 is used to achieve full immersion. At the same time, the agitator 9 fixed below the loading component will periodically sweep across the bottom of the storage cylinder to stir up the deposited solid marinade and keep the liquid uniformly mixed.

[0038] Automatic liquid suction: When the suction and discharge mechanism 14 rotates to the liquid level below the storage cylinder, the inner hole 12 on the rotating shaft 8 is connected to the first hole 113 of the suction and distribution component 11. At this time, the negative pressure pump 111 starts and draws air into the curved tube 141 of the suction and discharge mechanism 14 through the pipeline to form a negative pressure, and sucks the surrounding marinade liquid into the curved tube 141.

[0039] Automatic spraying: As the loading assembly 7 continues to rotate, the suction and discharge mechanism 14, filled with liquid, moves to the liquid surface above the storage cylinder. The inner hole 12 on the rotating shaft 8 then connects with the second hole 114 of the suction and distribution assembly 11. The second hole 114 is open to the atmosphere, allowing the internal pressure of the curved tube 141 to return to normal. The internal spring 144 pushes the movable plug 142 to reset, thereby forcefully spraying the liquid sucked in from the tube, forming a top spray on the pork below, realizing internal circulation of the liquid and gently accelerating the marinating process. After the marinating time reaches the predetermined time, the drive motor 6 and the negative pressure pump 111 are stopped, and the lifting support 5 is restarted to raise the top half-cylinder 2. The loading assembly 7 is then opened, and the marinated pork can be easily removed.

[0040] The injection end 3 includes an injection hole and a sealing plug. The injection hole is located at the top of the top half-cylinder 2, and the sealing plug is fitted into the injection hole.

[0041] Injection end 3 is used to inject the marinade, and the sealing plug is used to seal the injection hole.

[0042] The sealing mechanism 4 includes a top sealing frame 41, a bottom sealing frame 42, and a sealing strip 43. The top sealing frame 41 is fixed to the outer side of the bottom of the top half-cylinder 2, and the bottom sealing frame 42 is fixed to the outer side of the top of the bottom half-cylinder 1. The top of the bottom sealing frame 42 is provided with a sealing groove, and the sealing strip 43 is fixed to the top of the top sealing frame 41 and is adapted to the sealing groove.

[0043] The sealing mechanism 4 achieves a combined seal when the bottom half-cylinder 1 and the top half-cylinder 2 are combined into a storage cylinder, ensuring stable storage of the internal pickling liquid. It also rotates and agitates the rotating loading component 7. The sealing groove and sealing strip 43 cooperate to achieve a combined seal.

[0044] The lifting support part 5 includes a support plate 51, a crank arm 52 and an electric push rod 53. The support plate 51 is fixed to the end of the bottom half cylinder 1, the electric push rod 53 is fixed to the top of the support plate 51, one end of the crank arm 52 is connected to the free end of the electric push rod 53, and the other end of the crank arm 52 is fixedly connected to the top sealing frame 41.

[0045] By using the lifting support 5 to control the rise of the top half-cylinder 2, the bottom half-cylinder 1 is opened, providing a larger operating space at the top and completing the pork arrangement, with the electric push rod 53 providing power.

[0046] The slots 73 are arrayed on the bottom frame 71 and the top frame 72 respectively. The connecting mechanism includes a first fixing plate, a second fixing plate, a fixing rod and a locking cap. The first fixing plate and the second fixing plate are fixed to the sides of the bottom frame 71 and the top frame 72 respectively. The fixing rod is fixed to the top of the first fixing plate and is movably connected to the second fixing plate. The locking cap is threaded onto the outside of the fixing rod.

[0047] The pork is clamped and assembled using the top frame 72 and the bottom frame 71 to maintain stability. Numerous slots 73 are provided to allow for full contact and immersion in the marinade during rotation, thus completing the marinating process. Furthermore, quick assembly and disassembly are achieved by rotating and locking the fixing rod and locking cap in the connecting mechanism.

[0048] The bottom of the bottom frame 71 is fixedly connected to a connecting rod 10, which is fixedly connected to the toggle plate 9.

[0049] By following the eccentric rotation of the loading component 7, the toggle plate 9 moves along the bottom of the marinade, further agitating the liquid, preventing solid marinade from settling, ensuring uniformity of the liquid composition, and improving marinating efficiency.

[0050] The rotating shaft 8 has an inner hole 12 and an inner cavity 13 connected to each other. A suction / discharge mechanism 14 is connected to the bottom of the rotating shaft 8. A suction / discharge assembly 11 is located outside the bottom half-cylinder 1, communicating with the inner hole 12. The suction / discharge mechanism 14 includes a curved tube 141, a movable plug 142, a fixed ring 143, and a spring 144. The curved tube 141 is fixedly connected to the bottom of the rotating shaft 8 and communicates with the inner cavity 13. The movable plug 142 is movably fitted into the curved tube 141. Ring 143 is fixedly sleeved in curved tube 141, and spring 144 is fixedly connected between movable plug 142 and fixed ring 143. Suction distribution assembly 11 includes negative pressure pump 111, distribution sleeve 112, first hole 113 and second hole 114. The suction end of negative pressure pump 111 is connected to distribution sleeve 112. Distribution sleeve 112 is sleeved on the end of rotating shaft 8. First hole 113 and second hole 114 are both opened on distribution sleeve 112. First hole 113 and second hole 114 are connected to inner hole 12 and are both located on the rotation path of inner hole 12.

[0051] Air is drawn in by the suction and distribution assembly 11, and when the rotating shaft 8 rotates, the inner hole 12 is intermittently connected to the first hole 113 and the second hole 114. The first hole 113 is connected to the negative pressure pump 111. When the inner hole 12 is connected to the first hole 113, the gas in the curved tube 141 is drawn in through the inner cavity 13, causing the movable plug 142 to move under the negative pressure, thereby drawing the liquid into the curved tube 141. When the rotating shaft 8 drives the suction and discharge mechanism 14 to flip to the top, the ambient air is supplemented to one side of the curved tube 141 through the second hole 114, causing the movable plug 142 to reset and squeeze out the liquid. The liquid is sprayed above the liquid surface, further mixing the liquid.

[0052] A method for operating a low-temperature slow-marinating equipment for pork includes the following steps:

[0053] Step 1: Start the lifting support 5, which will move the top half-cylinder 2 upward and separate it from the bottom half-cylinder 1. Open the bottom half-cylinder 1, deflect the loading assembly 7 and keep it horizontal. Arrange the pork pieces to be processed in the bottom frame 71, and cover the top frame 72. Assemble and fix it through the connecting mechanism. Reset the top half-cylinder 2 so that the top half-cylinder 2 and the bottom half-cylinder 1 are sealed by the sealing mechanism 4.

[0054] Step 2: Open the injection end 3, pour in the marinade and submerge the pork, seal the injection end 3, start the drive motor 6, drive the loading component 7 to rotate through the rotating shaft 8, and make the meat pieces rotate slowly in the marinade to complete the slow marinating.

[0055] Step 3: During rotation, the loading component 7 drives the two side actuating plates to rotate, and when it rotates to the bottom, it agitates the liquid, causing the liquid to swirl.

[0056] Step 4: When rotating slowly, start the suction and distribution component 11. When the suction and discharge mechanism 14 rotates to the lower position, the suction and distribution component 11 draws in the air inside the suction and discharge mechanism 14, so that the suction and discharge mechanism 14 draws in the liquid. When the suction and discharge mechanism 14 rotates to the upper position of the liquid surface, the air pressure inside the suction and discharge mechanism 14 is restored, and the sucked liquid is sprayed out in the opposite direction.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
