Description

Technical Field

[0001] This invention relates to the field of meat product marinating technology, specifically to a beef marinating equipment and method. Background Technology

[0002] Meat curing is a key process in meat processing. Its purpose is to give meat products the desired flavor, color and texture through the penetration and diffusion of the curing solution, while also extending the product's shelf life. As an important raw material for meat products, the curing effect of yak meat directly affects the final product's taste, retention of nutrients and commercial value.

[0003] Traditional yak meat curing mainly employs static wet curing or dry curing methods, which involve placing the beef and curing liquid or dry curing seasoning in a container for a long period of time to soak. These methods have problems such as long curing cycles (usually requiring several hours to several days), uneven penetration of salt and seasonings, high labor intensity, low production efficiency, and susceptibility to microbial contamination. To improve the curing effect, the industry has developed vacuum tumbling curing technology. By rotating the tumbling drum, the meat pieces are shaken and rolled, promoting rapid penetration of the curing liquid in a vacuum environment, which significantly shortens the curing time and improves product uniformity.

[0004] Current vacuum tumbling techniques for beef mostly employ fixed paddles or spiral structures, making it difficult to dynamically adjust the tumbling process. This not only affects the tumbling efficiency but also easily leads to localized over-tumbling or under-tumbling, impacting the meat's texture and flavor. Furthermore, existing equipment typically adds seasonings all at once or adds them multiple times during the tumbling process through multiple stops. First, this easily results in uneven seasoning distribution and hinders precise control of seasoning penetration, affecting the beef's flavor. Second, the need for frequent stops and vacuuming reduces the continuity of the marinating process and makes the beef more susceptible to microbial contamination. Summary of the Invention

[0005] This invention provides a beef marinating device that, through a tumbling section, dynamically adjusts the tumbling of beef while simultaneously feeding and discharging the material. Furthermore, a drive control component adds seasonings to the device in small, frequent increments while maintaining its airtightness. This improves the efficiency of beef tumbling, ensures the texture and flavor of the meat, and prevents microbial contamination, thus solving the problems of low tumbling efficiency and poor taste and flavor mentioned in the background art.

[0036] 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. Example 1:

[0037] Reference Figures 1-7 A beef marinating device includes: a tumbling tank, comprising a first movable tank 3, a fixed tank 4, and a second movable tank 5, wherein the fixed tank 4 is rotatably connected to the first movable tank 3 and the second movable tank 5, and a receiving space is formed between the first movable tank 3, the fixed tank 4, and the second movable tank 5;

[0038] The three-section coaxial assembly structure connects the first movable tank 3, the second movable tank 5, and the fixed tank 4 in series, achieving functional zoning of the tanks and separating the rotation drive from the static control function. When the first movable tank 3 and the second movable tank 5 rotate, the fixed tank 4 remains stationary, forming a dynamic-static collaborative working mechanism. The fixed tank 4 serves as a stable platform for installing the storage system, avoiding pipe entanglement and poor sealing caused by rotation. It should be noted that the connection points of the first movable tank 3, the fixed tank 4, and the second movable tank 5 are all made of food-grade materials.

[0039] The tumbling section, located within the accommodating space, includes multiple sets of spiral tumbling plates 13 and tumbling adjustment components. The spiral tumbling plates 13 and tumbling adjustment components are evenly distributed at intervals within the accommodating space. Directly acting on the marinating of beef, the rotation of the first movable tank 3 and the second movable tank 5 drives the spiral tumbling plates 13 to provide basic tumbling. The tumbling adjustment components periodically deform to enhance the tumbling effect. During rotation, the beef undergoes alternating action from the spiral tumbling plates 13 and the tumbling adjustment components. The combination of rigidity and flexibility overcomes the shortcomings of single rigidity and flexibility, achieving dynamic optimization of tumbling intensity, avoiding local over- or under-tumbling, and significantly improving the uniformity of product texture.

[0040] The storage box 25 is connected to the top of the fixed tank 4. The storage box 25 is connected to the receiving space through the discharge valve port 27. A drive control component is provided between the storage box 25 and the fixed tank 4. When the tumbling adjustment component rotates to the storage box 25, the width-to-height ratio of the tumbling adjustment component is adjusted by the drive control component. At the same time, the seasonings in the storage box 25 pass through the discharge valve port and the tumbling adjustment component in sequence and enter the receiving space. The storage box 25 is provided with a guide slope 26 to make the seasonings always tend to move towards the discharge valve port 27 along the guide slope 26.

[0041] The storage box 25 stores seasonings and provides a gravity-fed feeding channel. When the tumbling adjustment component rotates to the bottom of the storage box 25, it triggers a switch. Under the action of gravity and negative pressure, the seasonings enter the receiving space from the storage box 25. No independent sensors and controllers are required. The rotation itself drives the synchronous control of feeding as soon as it is in place. The tumbling adjustment component creates a temporary storage bin to prevent the seasonings from spilling directly and causing splashing and uneven distribution. Mechanical linkage ensures quantitative control.

[0042] It also includes a feed inlet 8 connected to the end of the second movable tank 5, with a sealing cover 9 inside the feed inlet 8, and an air extraction port 10 connected to the sealing cover 9 to extract air from the containment space.

[0043] The sealing cap 9 can be repeatedly opened and closed for quick assembly and disassembly. The pipe joint welded at the air extraction port 10 connects to an external vacuum pump to create a vacuum marinating environment. The tumbling and vacuum work together to shorten the marinating time and inhibit the growth of aerobic bacteria.

[0044] Reference Figure 1The first movable tank 3 and the second movable tank 5 are mounted on the support 1 via symmetrically distributed guide wheels 11. The first movable tank 3 and the second movable tank 5 are connected to reinforcing rings 7 that are rolledly connected to the guide wheels 11. The support 1 is connected to a motor housing 2. The output end of the motor housing 2 is directly or indirectly connected to the axis of the first movable tank 3. It should be explained that the first movable tank 3 and the second movable tank 5 are connected by multiple spiral kneading plates 13, a kneading adjustment assembly, and an internal mounting rod 18. The multiple and evenly distributed connection points are sufficient to make the first movable tank 3 and the second movable tank 5 rotate synchronously, coaxially, and at the same speed. The guide wheels 11 provide support while reducing the resistance encountered when the first movable tank 3 and the second movable tank 5 rotate synchronously.

[0045] The four-point support layout (two guide wheels 11 on each side) and the annular track (reinforcing ring 7) connecting the first movable tank 3 and the second movable tank 5 allow the motor to be directly connected to the first movable tank 3 at the shaft end inside the motor housing 2. It can also be driven by a pulley and reducer structure. The frequency conversion control enables stepless speed regulation and one-button switching between forward and reverse rotation, meeting the process's precise requirements for speed and direction.

[0046] Reference Figure 3 The first movable tank 3 and the second movable tank 5 are both hollow cylinders with openings, and the openings of the first movable tank 3 and the second movable tank 5 are close to each other. The fixed tank 4 is annular. The openings of the first movable tank 3 and the second movable tank 5 are both provided with grooves 6. Both ends of the fixed tank 4 are rotatably connected to the first movable tank 3 and the second movable tank 5 through the grooves 6. The fixed tank 4 is connected to the bracket 1 through the fixing member 12.

[0047] The groove 6 is used to install the fixed tank 4. The groove 6 forms a complete receiving space with the first movable tank 3, the second movable tank 5 and the fixed tank 4, so as to ensure the stability of the whole structure during rotation.

[0048] Reference Figure 2 The two ends of the spiral kneading plate 13 are fixedly connected to the inner walls of the first movable tank 3 and the second movable tank 5, respectively. The spiral kneading plate 13 is tightly fitted to the inner wall of the fixed tank 4. When the spiral kneading plate 13 rotates in the first direction, the material in the containing space moves to the side of the first movable tank 3. When the spiral kneading plate 13 rotates in the second direction, the material in the containing space moves to the side of the second movable tank 5.

[0049] When the equipment rotates, the spiral kneading plate 13 scrapes across the inner wall of the fixed tank 4, removing the material adhering to the fixed tank 4, thereby keeping the inner wall of the fixed tank 4 clean. The self-cleaning function avoids cross-contamination. The spiral kneading plate 13 also serves as a drive connector, used to connect the first movable tank 3 and the second movable tank 5, so that the first movable tank 3 and the second movable tank 5 rotate synchronously, eliminating the need for an intermediate drive shaft. In addition, the same spiral kneading plate 13 can push beef in opposite directions by changing its direction of rotation. Based on the reversible principle of the spiral conveyor, the spiral helix angle determines the direction of axial thrust. By adjusting the rotation direction of the spiral kneading plate 13, automatic unloading of beef can also be achieved. Beef circulation can be achieved without tilting the equipment. The reciprocating motion allows the beef to experience different kneading intensities in different areas, resulting in more thorough mixing.

[0050] Reference Figure 2 , Figure 4 and Figure 6 Each set of tumbling adjustment components includes symmetrically distributed adjustment kneading plates 14. One end of the two sets of adjustment kneading plates 14 is connected by an elastic element 17, and the other end of the adjustment kneading plates 14 is tightly fitted to the inner wall of the first movable tank 3, the fixed tank 4, and the second movable tank 5 by a sealing element 16. The adjacent ends of the two sets of adjustment kneading plates 14 are sealed and connected by an extension element 15. Multiple sets of mounting rods 18 are evenly connected between the elastic element 17 and the inner wall of the first movable tank 3 and the second movable tank 5. The cross-section of the two sets of adjustment kneading plates 14 is an isosceles triangle, and the mounting rods 18 are elastic telescopic rod-shaped structures so that the side of the isosceles triangle closest to the first movable tank 3 and the second movable tank 5 is an adjustable side.

[0051] When subjected to external force, the adjusting kneading plate 14 rotates around the elastic element 17, and the sealing element 16 slides. The height of the triangular cross section changes synchronously with the base. During this process, the extension element 15 can ensure the sealing of the structure. The single-degree-of-freedom adjustment realizes the linkage change of the width-to-height ratio. The seal ensures that there is no leakage during the deformation process. Among them, when the elastic element 17 rotates, each mounting rod 18 extends and retracts synchronously to maintain the stability of the center position of the adjusting kneading plate 14, prevent the elastic element 17 from becoming unstable and bending, and ensure that the adjusting kneading plate 14 rotates symmetrically. The vertex curvature and overall shape change are realized through simple base adjustment to adapt to the kneading requirements of beef with different hardness.

[0052] Reference Figure 6 It also includes a support rod 21 that is symmetrically fixedly connected to the elastic member 17. The top end of the support rod 21 abuts against the inner wall of the fixed tank 4. A turntable 22 is rotatably connected to the support rod 21. Multiple sets of guide grooves 23 are evenly opened on the turntable 22. An adjusting rod 24 is symmetrically fixedly connected to the turntable 22. The end of the adjusting rod 24 abuts against the adjusting kneading plate 14. The support rod 21 is an elastic telescopic rod structure. There is resistance between the turntable 22 and the support rod 21, and the resistance is greater than the sum of the elastic forces of the extension member 15 and the elastic member 17.

[0053] The rotational motion of the equipment is converted into a passive drive mechanism for adjusting the kneading plate 14. During rotation, the top of the support rod 21 slides over the inner wall of the fixed tank 4. When it rotates to a specific position (at the storage box 25), the turntable 22 rotates under the action of the guide groove 23 and the slide rod 29. Subsequently, the adjusting rod 24 swings to push the adjusting plate to adjust the corresponding rotation of the kneading plate 14. No active actuators such as motors or cylinders are required. Pure mechanical linkage achieves position triggering and automatic adjustment. The system has high reliability and reduced cost. The mating surfaces of the turntable 22 and the support rod 21 are equipped with friction plates or tight fits, based on the friction self-locking principle. After adjustment, the friction torque is greater than 1000 N / A. The springback torque maintains the adjustment state, meaning that the turntable 22 can only rotate under a large external force. It needs to be explained that when the slide rod 29 drives one of the guide grooves 23 to rotate to the other side, the other guide groove 23 rotates to the starting position of the slide rod 29. When the adjusting rod 24 is perpendicular to the adjusting kneading plate 14, the adjusting kneading plate 14 is at its maximum angle. When the slide rod 29 engages with the guide groove 23 again, it will drive the end of the adjusting rod 24 past the point perpendicular to the adjusting kneading plate 14, and then reset under the action of various elastic elements, realizing the multi-level angle adjustment of the adjusting kneading plate 14.

[0054] Reference Figure 2 and Figure 6 It also includes a limiting partition 19 fixedly connected between two sets of adjusting kneading plates 14, a discharge valve port 27 located at a circumferential position between the two sets of limiting partitions 19, an outlet 20 opened on the side of the elastic element 17 near the limiting partition 19, and the outlet 20 is located between the two sets of limiting partitions 19, and two sets of support rods 21 are located on both sides of the two sets of limiting partitions 19 respectively.

[0055] The discharge port 20 is equipped with a one-way valve, which allows the material to be conveyed to the receiving space along the limiting partition 19. The material in the receiving space cannot be conveyed in reverse. When the seasoning falls through the storage box 25, under the action of the limiting partition 19, the seasoning is quickly conveyed into the receiving space through the discharge port 20 under the action of gravity and negative pressure. When the seasoning stops falling, the discharge port 20 is closed, realizing the directional conveying of the seasoning and preventing the seasoning from entering the mechanical gap. The structure is compact and avoids waste.

[0056] Reference Figure 4 , Figure 6 and Figure 7The drive control component includes an installation cavity 28 at the bottom of the storage box 25. A slide rod 29 is slidably connected inside the installation cavity 28. The top and bottom ends of the slide rod 29 extend into the storage box 25 and the receiving space, respectively. A stirring rod 30 is connected to the top end of the slide rod 29. A spring 31 is connected inside the installation cavity 28. A pressure plate 32 connected to the spring 31 is slidably connected to the slide rod 29. A control switch 33 is provided at the top of the installation cavity 28. The bottom end of the slide rod 29 is inclined along the rotation direction of the first movable tank 3. The slide rod 29 matches the guide groove 23. The control switch 33 is a push-button switch. A solenoid valve is provided inside the discharge valve port 27. The control switch 33 is electrically connected to the solenoid valve.

[0057] When the seal 16 rotates to the slide rod 29, its inclined surface drives the slide rod 29 to move towards the mounting cavity 28, thus not affecting the rotation of the seal 16. The pressure plate 32 presses the control switch 33, opening the solenoid valve. Simultaneously, the stirring rod 30 stirs the seasonings in the storage box 25, preventing condensation and blockage. The seasonings then fall under gravity and negative pressure. When the slide rod 29 is between the two sets of adjusting kneading plates 14, as the equipment continues to rotate, the slide rod 29 engages with the guide groove 23. (It should be noted that the contact surface between the slide rod 29 and the guide groove 23 is non-inclined to prevent the guide groove 23 from driving the slide rod.) 29 moves upward, and when slide rod 29 rotates to the other side of turntable 22, another guide groove 23 rotates to the initial engagement position of slide rod 29 and guide groove 23, thereby driving turntable 22 to rotate. Adjust the distance between the two ends of the two sets of adjusting rods 24 in the horizontal position, that is, adjust the angle of adjusting kneading plate 14. When the other side seal 16 moves to slide rod 29, it drives slide rod 29 to move upward again. Press control switch 33 again through pressure plate 32 to close solenoid valve and stop the addition of seasoning, thereby completing the addition of seasoning in small amounts and multiple times. During the addition process, the sealing of the equipment is ensured, the tumbling efficiency of beef is improved, the flavor of beef is guaranteed, and microbial contamination is avoided. Example 2:

[0058] Similar to Example 1, a method for marinating beef is proposed based on Example 1, including the following steps:

[0059] Step 1: Place the beef to be marinated and the seasonings in the designated location on the equipment;

[0060] Step 2: After the equipment is sealed, a vacuum is applied to the interior space of the equipment.

[0061] Step 3: Start the equipment to tumble the beef and continuously adjust the tumbling angle.

[0062] Step 4: During the tumbling process, the seasonings are added intermittently in small amounts using the negative pressure inside the equipment;

[0063] Step 4: During the process of adding seasonings, stir them continuously to prevent them from clumping and causing blockages;

[0064] Step 5: After the beef is marinated, reverse the rotation of the equipment to remove the beef.

[0065] Components not described in detail in this article are existing technologies.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
