Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically, it relates to a quick-freezing processing equipment for beef with a freshness-locking function. Background Technology

[0002] With increasing consumer demand for high-quality meat products, Wagyu beef has become a popular product in the high-end market due to its superior texture and flavor. However, Wagyu beef is prone to quality degradation during processing, storage, and transportation due to oxidation, microbial growth, or ice crystal breakage, affecting its taste and commercial value. Therefore, how to achieve efficient quick-freezing and freshness-locking packaging in the processing stage has become a pressing technical challenge for the industry.

[0003] Traditional meat quick-freezing technology mainly uses large cold storage facilities or tunnel-type quick-freezing equipment, which has the following drawbacks:

[0004] Existing technologies typically separate quick-freezing and vacuum packaging into separate processes, requiring manual material transfer. This not only increases the risk of contamination but also leads to loss of cold energy, affecting the preservation effect. Although some equipment can achieve continuous quick-freezing, it lacks intelligent feeding and packaging coordination mechanisms, relies on manual operation, is inefficient, and makes it difficult to guarantee hygiene standards.

[0005] To address the aforementioned issues, this application proposes a quick-freezing processing device for beef with a freshness-locking function. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a beef quick-freezing processing equipment with freshness-locking function to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A quick-freezing processing device for beef with freshness-locking function includes a support column, a rotating cap rotatably mounted on the support column, a rotating plate fixedly mounted on the rotating cap, a positioning plate rotatably connected to the rotating cap, and two symmetrically arranged brackets fixedly mounted on the bottom of the positioning plate, the brackets being fixedly connected to the support column.

[0009] The quick-freezing mechanism includes multiple arc-shaped cold boxes, which are fixedly installed on the top of a rotating plate, with an opening at the bottom and an air pump installed on the top of the arc-shaped cold boxes.

[0010] The feeding and packaging mechanism includes a Y-shaped feeding box, which is fixedly installed on the bottom of a positioning plate. The positioning plate has a feeding hole located above the Y-shaped feeding box, and a mounting frame is installed at the bottom of the Y-shaped feeding box.

[0011] The motor is fixedly mounted on one of the two brackets. A drive gear is fixedly mounted on the output shaft of the motor. Teeth are installed on the outside of the rotating cap. The drive gear and the teeth mesh with each other.

[0012] Preferably, the quick-freezing mechanism further includes multiple placement plates, which are rotatably mounted on a rotating plate in a ring, and the placement plates cooperate with the discharge holes.

[0013] By setting up multiple placement plates, sliced ​​beef can be placed. When the placement plate rotates to the feeding hole position, the placement plate loses the support of the positioning plate, causing the placement plate to swing downwards, thereby guiding the beef on the placement plate into the Y-shaped feeding box. When the rotating plate drives the placement plate to continue rotating, when the placement plate rotates to the side of the feeding hole, the side contacts the placement plate, thereby pushing the placement plate back into contact with the ground of the rotating plate.

[0014] Preferably, an arc-shaped air guide box is installed on the top inner wall of the arc-shaped cold box, and multiple atomizing nozzles are installed at the bottom of the arc-shaped air guide box, and the arc-shaped air guide box is connected to a suction pump.

[0015] The cooled liquid nitrogen or liquid carbon dioxide is drawn in by a vacuum pump and injected into an arc-shaped air guide box, and then applied to the beef through an atomizing nozzle to freeze the beef quickly and continuously.

[0016] Preferably, the feeding and packaging mechanism further includes an L-shaped guide plate, which is rotatably connected to one inner wall of the Y-shaped feeding box. Both ends of the L-shaped guide plate are provided with sealing strips, which cooperate with the inner walls of both sides of the Y-shaped feeding box.

[0017] The L-shaped guide plate facilitates the feeding of beef through the discharge hole, and the two sealing strips seal the Y-shaped feeding box, allowing the frozen beef to be vacuum-packed for preservation during packaging.

[0018] Preferably, a vacuum pump is installed on one side of the Y-shaped feeding box, the inlet of the vacuum pump is connected to the Y-shaped feeding box, and a conduit is installed on the outlet of the vacuum pump. The top end of the conduit is connected to the top of the Y-shaped feeding box, and the top end of the conduit cooperates with the L-shaped guide plate.

[0019] By using a vacuum pump, the gas inside the Y-shaped feeding box can be easily extracted, thus creating a vacuum inside the Y-shaped feeding box. At the same time, the exhaust gas duct acts on one side of the L-shaped guide plate and blows the L-shaped guide plate to change its angle, causing one side of the L-shaped guide plate to press against the inner wall of one side of the Y-shaped feeding box, thereby sealing the Y-shaped feeding box.

[0020] Preferably, positioning seats are fixedly installed on both inner walls of the Y-shaped feeding box, and a top spring is fixedly installed on one side of the positioning seat. One end of the top spring is fixedly connected to the inner side of the L-shaped guide plate.

[0021] The positioning seat is fixedly connected to the inner wall of the Y-shaped feeding box, and the top spring acts on the L-shaped guide plate, so that the L-shaped guide plate can automatically reset when the air is blown out of the guide tube, thereby opening the Y-shaped feeding box and facilitating material feeding.

[0022] In summary, the technical effects and advantages of this utility model are as follows:

[0023] The circular layout of the rotating plate and multiple placement plates enables automated production line operation of continuous feeding, quick freezing, unloading and vacuum packaging of beef, significantly improving processing efficiency. When the placement plate rotates to the unloading hole position, it automatically tilts downward to unload by gravity. When it leaves, it resets by side contact, without the need for an additional drive device. The structure is ingenious and energy-saving.

[0024] With its top arc-shaped air guide box and bottom atomizing nozzle design, combined with the injection of liquid nitrogen / liquid carbon dioxide by an air pump, it achieves uniform and rapid low-temperature atomization coverage, ensuring that the cell structure of Wagyu beef is not damaged by ice crystals, resulting in better freshness preservation. The bottom opening of the cold box allows cold air to act directly on the beef, while dynamically cooperating with the rotating plate to prevent cold air leakage, making it energy-efficient and effective.

[0025] When the vacuum pump draws air, the discharged gas blows through the conduit onto the L-shaped guide plate, causing it to press against the sealing strip and automatically close the Y-shaped feeding box, creating a vacuum environment. After the airflow is stopped, the top spring returns the guide plate to its original position, achieving automatic filling and sealing of the packaging bag in one integrated process. The L-shaped guide plate combines material guiding and sealing functions, simplifying the complex mechanical sealing components in traditional vacuum packaging. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Reference Figure 1-5 A quick-freezing processing equipment for beef with freshness-locking function includes a support column 1, a rotating cap 2 rotatably mounted on the support column 1, a rotating plate 4 fixedly mounted on the rotating cap 2, a positioning plate 3 rotatably connected to the rotating cap 2, and two symmetrically arranged brackets 7 fixedly mounted on the bottom of the positioning plate 3, with the brackets 7 fixedly connected to the support column 1.

[0035] The quick-freezing mechanism 5 includes multiple arc-shaped cold boxes 52, which are fixedly installed on the top of the rotating plate 4, and the bottom of the arc-shaped cold boxes 52 is open. An air pump 55 is installed on the top of the arc-shaped cold boxes 52.

[0036] The feeding and packaging mechanism 6 includes a Y-shaped feeding box 61, which is fixedly installed at the bottom of the positioning plate 3. The positioning plate 3 has a feeding hole 69, which is located above the Y-shaped feeding box 61. An installation frame 62 is installed at the bottom of the Y-shaped feeding box 61. The packaging bag can be placed on the installation frame 62, so that the Y-shaped feeding box 61 can be used for feeding.

[0037] The motor 8 is fixedly mounted on one of the two brackets 7. The output shaft of the motor 8 is fixedly mounted with a drive gear 9. The outer side of the rotating cap 2 is mounted with teeth 10. The drive gear 9 and the teeth 10 mesh with each other.

[0038] Reference Figure 3 and Figure 4The quick-freezing mechanism 5 also includes multiple placement plates 51, which are rotatably mounted in a ring on the rotating plate 4. The placement plates 51 cooperate with the discharge holes 69. An arc-shaped air guide box 53 is installed on the top inner wall of the arc-shaped cold box 52. Multiple atomizing nozzles 54 are installed at the bottom of the arc-shaped air guide box 53, which is connected to a vacuum pump 55. The vacuum pump 55 draws in cooled liquid nitrogen or liquid carbon dioxide and injects it into the arc-shaped air guide box 53, which then acts on the beef through the atomizing nozzles 54, rapidly and continuously freezing the beef. The multiple placement plates 51 are used to place sliced ​​beef. When the placement plate 51 rotates to the feeding hole 69, the placement plate 51 loses the support of the positioning plate 3, causing the placement plate 51 to swing downwards, thereby guiding the beef on the placement plate 51 into the Y-shaped feeding box 61. When the rotating plate 4 drives the placement plate 51 to rotate continuously, when the placement plate 51 rotates to the side of the feeding hole 69, the side contacts the placement plate 51, thereby pushing the placement plate 51 so that the placement plate 51 is back in contact with the ground of the rotating plate 4.

[0039] Reference Figure 4 and Figure 5 The feeding and packaging mechanism 6 also includes an L-shaped guide plate 65. An L-shaped guide plate 65 is rotatably connected to one inner wall of the Y-shaped feeding box 61. Both ends of the L-shaped guide plate 65 are equipped with sealing strips 66, which cooperate with the inner walls of both sides of the Y-shaped feeding box 61. A vacuum pump 63 is installed on one side of the Y-shaped feeding box 61. The inlet of the vacuum pump 63 is connected to the Y-shaped feeding box 61, and a conduit 64 is installed on the outlet of the vacuum pump 63. The top end of the conduit 64 is connected to the top of the Y-shaped feeding box 61, and the top end of the conduit 64 cooperates with the L-shaped guide plate 65. Positioning seats 67 are fixedly installed on both inner walls of the Y-shaped feeding box 61. A top spring 68 is fixedly installed on one side of the positioning seat 67, and one end of the top spring 68 is fixedly connected to the inner side of the L-shaped guide plate 65. The vacuum pump 63 facilitates the extraction of gas from the Y-shaped feeding box 61. This creates a vacuum inside the Y-shaped feeding box 61. Simultaneously, the exhaust gas conduit 64 acts on one side of the L-shaped guide plate 65, causing the angle of the L-shaped guide plate 65 to change. This causes one side of the L-shaped guide plate 65 to press against the inner wall of one side of the Y-shaped feeding box 61, thus sealing the Y-shaped feeding box 61. The L-shaped guide plate 65 facilitates the guiding of beef from the discharge hole 69. The two sealing strips 66 further seal the inside of the Y-shaped feeding box 61, allowing for vacuum preservation packaging of the frozen beef. The positioning seat 67 is fixedly connected to the inner wall of the Y-shaped feeding box 61, and the top spring 68 acts on the L-shaped guide plate 65, causing it to automatically reset when the air from the conduit 64 is removed. This allows the L-shaped guide plate 65 to open the Y-shaped feeding box 61, facilitating the feeding of beef.

[0040] Working principle: During operation, sliced ​​beef is placed on the placement plate 51, and the motor 8 is switched on. The output shaft of the motor 8 drives the rotating cap 2 to rotate through the meshing of the drive gear 9 and the teeth 10. The rotating cap 2 drives the rotating plate 4 to rotate, and the rotating plate 4 moves the beef on the placement plate 51 into the arc-shaped cold box 52. The vacuum pump 55 draws in cooled liquid nitrogen or liquid carbon dioxide and injects it into the arc-shaped air guide box 53, which then acts on the beef through the atomizing nozzle 54, rapidly and continuously freezing the beef. The multiple placement plates 51 can be used to place the sliced ​​beef. When the placement plate 51 rotates to the discharge hole 69, the placement plate 51 loses the support of the positioning plate 3, causing the placement plate 51 to swing downwards, thus guiding the beef on the placement plate 51 into the Y-shaped feeding box 61. When the rotating plate 4 drives the placement plate 51 to continue rotating, when the placement plate 51 rotates to the side of the discharge hole 69, the side contacts the placement plate 51, thus pushing the placement plate 51. This allows the placement plate 51 to re-adhere to the ground of the rotating plate 4. The L-shaped guide plate 65 facilitates the guidance of the beef being fed through the discharge hole 69. The two sealing strips 66 seal the inside of the Y-shaped feeding box 61, enabling vacuum preservation packaging of the frozen beef during packaging. The positioning seat 67 is fixedly connected to the inner wall of the Y-shaped feeding box 61, and the top spring 68 acts on the L-shaped guide plate 65, ensuring that the L-shaped guide plate 65 can... The system automatically resets, allowing the L-shaped guide plate 65 to open the Y-shaped feeding box 61 for easy material feeding. The vacuum pump 63 facilitates the extraction of gas from the Y-shaped feeding box 61, creating a vacuum inside. Simultaneously, the exhaust gas conduit 64 acts on one side of the L-shaped guide plate 65, causing the angle of the L-shaped guide plate 65 to change, resulting in one side of the L-shaped guide plate 65 pressing against the inner wall of one side of the Y-shaped feeding box 61, thereby sealing the Y-shaped feeding box 61.
