Description

Technical Field

[0001] This invention belongs to the technical field of meat processing equipment, specifically relating to a beef marinating device for processing beef. Background Technology

[0002] The meat processing industry is rapidly developing towards automation, intelligence, and standardization. Marinating, as a key process for enhancing meat flavor and extending shelf life, has seen significant technological upgrades. As market demands for both the quality and efficiency of beef products continue to rise, traditional manual marinating is gradually being replaced by mechanized equipment. Currently, mainstream equipment includes vacuum tumblers and brine injectors. These machines achieve high efficiency in the marinating process through automated control, driving the continuous expansion of the industry's production scale. Simultaneously, consumer demand for uniform meat texture and nutrient retention is prompting marinating equipment to iterate towards precise control and gentler processing, aiming to achieve a balance between efficiency and quality.

[0003] Most existing beef marinating equipment uses a drum-type structure. Drum-type marinating equipment relies on the rotation of the drum to allow the meat pieces to fall freely and mix with the marinade. This method easily leads to the meat pieces sticking together, making it difficult for the marinade to penetrate evenly into the meat, resulting in an overly salty surface and insufficient flavor in the center, significantly prolonging the marinating time. While some equipment adds patting or kneading structures, they lack targeted positioning and mechanisms of action. The kneading force cannot be precisely controlled; either insufficient force fails to accelerate the marinating process, or excessive force damages the beef's fiber structure, leading to a deterioration in meat quality and affecting product consistency.

[0004] Therefore, it is necessary to study a method that can achieve uniform marinating of beef while precisely controlling the squeezing force to avoid excessive squeezing, so that the beef retains its original intact fiber state, greatly reducing the difficulty of damaging the meat structure due to kneading, and facilitating the standardized implementation of the marinating process. Summary of the Invention

[0005] To address the aforementioned shortcomings in the existing technology, the present invention provides a beef marinating device for processing beef, which solves the technical problems of uneven marinating of beef and damage to the meat structure caused by improper control of patting or kneading force in the existing technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A beef marinating apparatus for processing beef includes: a frame, a roller, a kneading mechanism, a driving mechanism, and a stirring mechanism; The roller is rotatably mounted on the frame. The roller is a hollow barrel with openings at both ends. The roller is provided with an end cap, a feed inlet, and a sealing cap. The end cap is fixedly mounted at the opening of the roller away from the feed inlet. Multiple fixed brackets are evenly arranged around the end cap. A material trough is provided between two adjacent fixed brackets. The sealing cap is detachably mounted at the feed inlet. The kneading mechanism includes a fixed plate, a mounting bracket, eccentric kneading rods, and a transmission assembly. The fixed plate is fixedly connected to the fixed bracket, and the mounting bracket is fixedly mounted on the fixed plate. The two ends of the multiple sets of eccentric kneading rods are respectively rotatably mounted on the fixed plate and the mounting bracket, and the multiple sets of eccentric kneading rods are connected to the transmission assembly. The drive mechanism is mounted on the frame, and the end cover is connected to the drive mechanism; The actuating mechanism is rotatably disposed inside the drum, and the actuating mechanism is fixedly connected to the driving mechanism.

[0007] Furthermore, a control component is provided on the frame, and the control component is electrically connected to the drive mechanism.

[0008] Furthermore, the end cap also includes a filter screen, with both sides of the filter screen fixedly connected to two adjacent fixed supports.

[0009] Furthermore, the eccentric kneading rod includes a rotating shaft, a torque limiter, and a connecting rod. The rotating shaft and the torque limiter are connected by the connecting rod. The rotating shaft is rotatably mounted on the mounting bracket, and the torque limiter is rotatably mounted on the fixed plate.

[0010] Furthermore, the kneading mechanism also includes a rubber ball, which is rotatably mounted on the connecting rod.

[0011] Furthermore, the transmission assembly includes a first drive shaft, a drive gear, and a gear ring. The first drive shaft is rotatably disposed between the fixed plate and the fixed bracket. The first drive shaft is connected to the eccentric kneading rod. The gear ring is fixedly disposed on the frame. The first drive shaft is connected to the gear ring through the drive gear.

[0012] Furthermore, the driving mechanism includes a second driving shaft and a driving motor, the second driving shaft being fixedly connected to the end cover, and the driving motor being connected to the second driving shaft.

[0013] Furthermore, the actuating mechanism includes a third drive shaft and an arc-shaped lever, the third drive shaft being connected to the second drive shaft, and the arc-shaped lever being fixedly mounted on the third drive shaft.

[0014] Furthermore, the concave side of the arc-shaped lever faces the rotation direction of the first drive shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention discloses a beef marinating device for processing beef. Through the synergistic action of a kneading mechanism and a stirring mechanism, the kneading mechanism can perform all-round gentle kneading of the beef, accelerating the penetration of marinade into the beef. The stirring mechanism can prevent the beef from sticking together and clumping, ensuring a balanced movement trajectory of the beef within the drum and preventing excessive differences in contact time between some beef and the marinade. Simultaneously, the material trough can slowly release the marinade during the drum's rotation, extending the contact time between the beef and the marinade, further ensuring marinating uniformity, significantly shortening the marinating cycle, and adapting to the needs of large-scale production.

[0016] 2. The present invention discloses a beef marinating device for processing beef. The device can monitor the kneading force in real time through a torque limiter. When the pressure exceeds the limit, the connection is automatically disconnected to avoid damaging the beef fibers due to excessive kneading force. After the pressure is restored, the device is automatically reset to ensure the continuity of operation. At the same time, the rubber ball setting enables flexible kneading and reduces scratches on the surface of the beef. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0021] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] Please see Figures 1 to 9 As shown, a beef marinating apparatus for processing beef includes: a frame 1 for support, a roller 2 for driving the beef and marinade to roll and mix, a kneading mechanism 3 for squeezing and kneading the beef to accelerate marinating, a drive mechanism 4 for driving the roller 2 and the kneading mechanism 3 to operate, and a stirring mechanism 5 for preventing the beef from sticking together and clumping together and preventing uneven contact time between the beef and the marinade.

[0023] A control component 11 is installed on the frame 1, and the control component 11 is electrically connected to the drive mechanism 4. The start / stop and operating status regulation of the drive mechanism 4 can be achieved through the control component 11.

[0024] The roller 2 is rotatably mounted on the frame 1. The roller 2 is a hollow barrel with openings at both ends. The roller 2 is equipped with an end cap 21, a feed inlet 22, and a sealing cap 23. The end cap 21 is fixedly mounted at the opening of the roller 2 away from the feed inlet 22. Multiple fixed supports 211 are evenly arranged around the end cap 21. A trough 212 is provided between two adjacent fixed supports 211. This means that the marinade can enter the trough 212 between two adjacent fixed supports 211. The marinade in the trough 212 can slowly flow out during the rotation and as the roller 2 rises, falling onto the beef and increasing the contact time between the beef and the marinade. Specifically, the end cap 21 also includes a filter screen 213. The filter screen 213 is fixedly connected to two adjacent fixed supports 211 on both sides. The filter screen 213 prevents the beef from entering the trough 212, avoiding separation of the beef from the kneading mechanism 3, which would prevent squeezing and kneading.

[0025] The sealing cap 23 is detachably installed at the feed inlet 22.

[0026] The kneading mechanism 3 includes a fixed plate 31, a mounting bracket 32, eccentric kneading rods 33, and a transmission assembly. The fixed plate 31 is fixedly connected to the fixed bracket 211, and the mounting bracket 32 ​​is fixedly mounted on the fixed plate 31. The two ends of the multiple sets of eccentric kneading rods 33 are respectively rotatably mounted on the fixed plate 31 and the mounting bracket 32. The multiple sets of eccentric kneading rods 33 are connected to the transmission assembly, which means that the transmission assembly can simultaneously drive the eccentric kneading rods 33 connected to it to rotate.

[0027] Specifically, the eccentric kneading rod 33 includes a rotating shaft 331, a torque limiter 332, and a connecting rod 333. The rotating shaft 331 and the torque limiter 332 are connected via the connecting rod 333. The rotating shaft 331 is rotatably mounted on the mounting bracket 32, and the torque limiter 332 is rotatably mounted on the fixed plate 31. This means that when the pressure on the eccentric kneading rod 33 exceeds the limit, the torque limiter 332 will automatically disconnect the eccentric kneading rod 33 from the first drive shaft 34 to prevent excessive pressure from damaging the beef fiber structure. After the beef position is adjusted and the pressure returns to normal, the torque limiter 332 automatically reconnects the two, ensuring the kneading operation continues stably and effectively preventing damage to the meat structure.

[0028] Specifically, the kneading mechanism 3 also includes a rubber ball 334, which is rotatably mounted on the connecting rod 333.

[0029] This can be understood as follows: when the beef falls into the kneading mechanism 3 and onto the filter screen 213 between adjacent kneading mechanisms 3, the rubber ball 334 is rotatably mounted on the connecting rod 333, and can move with the connecting rod 333 to gently knead the beef from both sides.

[0030] Specifically, the transmission assembly includes a first drive shaft 34, a drive gear 35, and a gear ring 36. The first drive shaft 34 is rotatably mounted between the fixed plate 31 and the fixed bracket 211, and is connected to the eccentric kneading rod 33. The gear ring 36 is fixedly mounted on the frame 1, and the first drive shaft 34 is connected to the gear ring 36 via the drive gear 35. It can be understood that when the roller 2 rotates, the gear ring 36 drives the first drive shaft 34 to rotate via the drive gear 35, thereby driving the eccentric kneading rod 33 on the kneading mechanism 3 to rotate.

[0031] The drive mechanism 4 is mounted on the frame 1, and the end cover 21 is connected to the drive mechanism 4. Specifically, the drive mechanism 4 includes a second drive shaft 41 and a drive motor 42. The second drive shaft 41 is fixedly connected to the end cover 21, and the drive motor 42 is connected to the second drive shaft 41.

[0032] The actuating mechanism 5 is rotatably disposed inside the roller 2, and is fixedly connected to the driving mechanism 4. Specifically, the actuating mechanism 5 includes a third driving shaft 51 and an arc-shaped lever 52. The third driving shaft 51 is connected to the second driving shaft 41, and the arc-shaped lever 52 is fixedly disposed on the third driving shaft 51.

[0033] This can be understood as the third drive shaft 51 and the arc-shaped lever 52 rotating together with the second drive shaft 41.

[0034] Specifically, the concave side of the arc-shaped lever 52 faces the rotation direction of the first drive shaft 34. This can be understood as follows: during the rotation of the roller 2, after the beef reaches above the roller 2 and slides out of the kneading mechanism 3, the beef falls onto the concave side of the arc-shaped lever 52. The rotating arc-shaped lever 52 then carries the beef to the other side and onto the bottom of the roller 2. This effectively prevents the beef from sticking together and also prevents it from sliding out of the kneading mechanism 3 and falling directly into the eccentric kneading rod 33 at the bottom of the roller 2 or above the filter screen 213, and then rising again, resulting in some beef having a longer contact time with the marinade and some having a shorter contact time, ultimately causing uneven marinating.

[0035] The working principle of this invention is as follows: Before marinating, the sealing cap 23 is removed from the inlet 22, and the beef to be marinated and an appropriate amount of marinade are added into the drum 2. Some of the marinade will flow into the trough 212 between the fixed brackets 211 on the end cap 21. It should be noted that the height of the marinade below the drum 2 is higher than the filter screen. Preferably, the marinade submerges the beef below the drum 2. The filter screen 213 can prevent the beef from entering the trough 212, ensuring that the beef is always in the area that can be acted upon by the kneading mechanism 3. After the feeding is completed, the sealing cap 23 is installed back into the inlet 22 to seal it. The drive mechanism 4 is started through the control component 11 on the frame 1, and the drive motor 42 is controlled to operate.

[0036] After the drive motor 42 is powered on, it drives the second drive shaft 41 to rotate. The second drive shaft 41 synchronously drives the end cap 21 and the roller 2, which are fixedly connected to it, to rotate around the frame 1, so that the beef and marinade in the roller 2 are initially mixed. At the same time, the second drive shaft 41 drives the third drive shaft 51 of the actuating mechanism 5 to rotate synchronously. The arc-shaped lever 52 on the third drive shaft 51 rotates with the shaft. Since the concave side of the arc-shaped lever 52 faces the rotation direction of the first drive shaft 34, when the beef rotates to the top with the roller 2 and slides down from the kneading mechanism 3, it will fall precisely onto the concave side of the arc-shaped lever 52. The arc-shaped lever 52 continues to rotate, smoothly bringing the beef to the other side and then letting it fall to the bottom of the roller 2, avoiding the beef from sticking together and clumping together. At the same time, it balances the movement trajectory of the beef in the roller 2 and prevents some beef from repeatedly rising quickly, resulting in uneven contact time with the marinade.

[0037] While the drum 2 rotates, the transmission components of the kneading mechanism 3 operate synchronously. Since the gear ring 36 is fixed to the frame 1, the drive gear 35, which rotates with the drum 2, revolves around the gear ring 36, thereby driving the first drive shaft 34 to rotate. The first drive shaft 34 drives multiple sets of eccentric kneading rods 33 to rotate synchronously. The shaft 331 of the eccentric kneading rod 33 rotates stably on the mounting bracket 32, and the torque limiter 332 rotates synchronously on the fixed plate 31. The connecting rod 333 moves eccentrically with the rotation of the eccentric kneading rod 33, and the rubber ball 334 on the connecting rod 333 rotates accordingly, gently squeezing and kneading the beef inside the drum 2 from both sides, accelerating the penetration of the marinade into the beef.

[0038] During the kneading process, if the beef overlaps excessively or becomes too wide, causing the pressure on the eccentric kneading rod 33 to exceed the limit, the torque limiter 332 will automatically disconnect the eccentric kneading rod 33 from the first drive shaft 34 to prevent excessive pressure from damaging the beef fiber structure. After the beef position is adjusted and the pressure returns to normal, the torque limiter 332 will automatically reconnect the two, ensuring the kneading operation continues stably. Simultaneously, as the roller 2 rotates and rises, the marinade in the feed trough 212 slowly flows out and evenly falls onto the surface of the beef, further extending the contact time between the beef and the marinade and improving the marinating effect.

[0039] After marinating, the drive motor 42 is turned off by the control component 11. After the drum 2 stops rotating completely, the sealing cover 23 is removed and the marinated beef is taken out from the feed port 22, thus completing the entire marinating process.
