Description

Technical Field

[0001] This utility model relates to the field of beef processing technology, specifically to a cold chain preservation and sterilization device for beef at low temperature. Background Technology

[0002] In the food processing industry, beef, as a primary processed product of cattle (Bovine cattle or buffalo), is a highly sought-after meat globally due to its rich nutritional value and unique flavor. Currently, after processing, beef is generally stored and preserved using low-temperature refrigeration to inhibit microbial growth and extend shelf life. To further enhance beef safety, the industry often incorporates ultraviolet (UV) irradiation technology for sterilization during refrigeration. However, existing beef refrigeration sterilization processes have significant technical flaws. In practice, beef is often stacked on pallets or other supporting structures. This stacking method inevitably leads to some areas of the beef being blocked, making it difficult for UV light to cover evenly, resulting in sterilization blind spots and severely impacting the sterilization effect. Furthermore, after sterilization and refrigeration, the beef is stored inside the equipment, requiring operators to often enter the refrigerated space to retrieve it. This not only increases the risk of operators being exposed to the low-temperature environment but is also extremely inconvenient. Therefore, there is an urgent need to improve and refine existing beef refrigeration sterilization and retrieval technologies to meet the industry's high-quality development needs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a low-temperature refrigeration and sterilization treatment device for cold chain fresh beef, which solves the problems mentioned in the background technology.

[0004] The solution of this utility model to the above-mentioned technical problems is as follows:

[0005] A cold chain preservation and sterilization device for beef includes a refrigerator, wherein an ultraviolet irradiation lamp is installed inside the refrigerator;

[0006] A fixing frame is fixedly installed on the top surface of the inner wall of the refrigerator. A limit rod is welded inside the fixing frame. A first drive motor is installed on the rear end surface of the fixing frame. A lead screw is provided at the output shaft end of the first drive motor.

[0007] The bottom end of the fixed frame is provided with a second drive motor. The output end of the second drive motor is mounted with a connecting frame via a rotating shaft. A fixing block is welded to the bottom end of the connecting frame, and a hook is provided on the bottom end of the fixing block.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a support block is fixedly installed on the bottom surface of the refrigerator, and an anti-slip pad is installed on the bottom surface of the support block.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The support blocks hold the refrigerator firmly on the ground, ensuring overall stability. The anti-slip feet increase friction between the unit and the ground, further supporting the refrigerator during installation.

[0012] Furthermore, the front end of the refrigerator is fitted with a cover plate via a hinge, and a handle is mounted on the cover plate.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The hinged connection allows the cover to be opened and closed, making it convenient for operators to hang the beef on the hook for cold storage and sterilization, and to hold the handle to open the cover and take out the beef after processing.

[0015] Furthermore, a mounting bracket is installed on the second drive motor, and a guide block is welded on the mounting bracket. The guide block is slidably sleeved on the limiting rod, and the guide block is threaded onto the lead screw.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] When the first drive motor rotates the lead screw, the guide block engages with the lead screw via a thread and slides onto the limiting rod. The limiting rod guides and limits the movement, ensuring the guide block moves smoothly along the axial direction of the lead screw. This, in turn, drives the mounting bracket, the second drive motor, and the hook to move horizontally within the refrigerator. After the beef sterilization process is complete, the first drive motor can be controlled to move the hook holding the beef to a position near the refrigerator lid. This allows operators to easily remove the beef directly from the refrigerator opening without needing to reach deep into the refrigerator, greatly improving the convenience and efficiency of beef handling. It also reduces the time operators are exposed to the low-temperature environment, lowering the risk of them getting frostbite. Furthermore, when placing beef, the hook can be moved to a suitable position for easy hanging, enhancing the convenience and user-friendliness of the entire beef processing procedure.

[0018] Furthermore, there are two connecting frames, which are symmetrically distributed at equal intervals relative to the rotating shaft.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] Two symmetrically distributed connecting frames increase the hanging position and ensure that the beef hanging on the hooks remains stable during cold storage and sterilization, preventing the beef from swaying or tilting due to uneven force. The evenly distributed connecting frames allow for smoother adjustment of the beef's position and angle during hook rotation (achieved by a second drive motor rotating the shaft). This facilitates comprehensive sterilization of the beef by the ultraviolet lamp from multiple angles, eliminating sterilization blind spots and improving the sterilization effect.

[0021] Furthermore, a connecting block is welded onto the hook, and the connecting block is fitted inside the fixing block.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The connecting block is fitted inside the fixed block, allowing personnel to rotate the hook to adjust the hanging angle according to the actual needs of beef hanging.

[0024] This invention provides a low-temperature refrigeration and sterilization device for cold chain preservation of beef. It has the following beneficial effects:

[0025] The guide block mounted on the second drive motor works in conjunction with the lead screw and limit rod. When the first drive motor drives the lead screw to rotate, the limit rod guides and limits the movement, allowing the guide block to move smoothly along the lead screw axis, thereby driving the hooks and other components to move horizontally within the refrigerator. After the beef sterilization process is completed, the hooks holding the beef can be moved closer to the refrigerator opening by controlling the first drive motor. Operators can then retrieve the beef without having to reach deep into the refrigerator, improving the convenience and efficiency of beef retrieval and reducing the time operators spend in contact with the low-temperature environment, thus lowering the risk of operators getting frostbite and demonstrating the user-friendly design of the device.

[0026] The system features two connecting frames symmetrically distributed at equal intervals relative to the rotating shaft. This structure increases the number of hanging positions and ensures that the beef suspended on the hooks maintains a stable hanging position during cold storage and sterilization, preventing the beef from swaying or tilting due to uneven force. When the second drive motor rotates the shaft, the evenly distributed connecting frames allow the hooks to more smoothly adjust the position and angle of the beef during rotation. This facilitates comprehensive sterilization of the beef by the ultraviolet lamp from multiple angles, effectively eliminating sterilization blind spots, thereby improving the sterilization effect and ensuring the quality of the beef.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A cold chain preservation and sterilization device for beef includes a refrigerator 1, and an ultraviolet irradiation lamp 102 is installed inside the refrigerator 1.

[0040] A fixed frame 2 is fixedly installed on the top surface of the inner wall of the refrigerator 1. A limit rod 201 is welded inside the fixed frame 2. A first drive motor 202 is installed on the rear end surface of the fixed frame 2. A lead screw 203 is provided at the output shaft end of the first drive motor 202.

[0041] The bottom end of the fixed frame 2 is provided with a second drive motor 302. The output end of the second drive motor 302 is mounted with a connecting frame 304 through a rotating shaft 305. A fixing block 306 is welded to the bottom end of the connecting frame 304. A hook 303 is provided on the bottom end of the fixing block 306.

[0042] A support block 101 is fixedly installed on the bottom surface of the refrigerator 1. Anti-slip pads are installed on the bottom surface of the support block 101. The support block 101 supports the refrigerator 1 on the ground, ensuring the overall stability of the device. The anti-slip pads increase the friction between the device and the ground, thus providing support for the refrigerator 1.

[0043] The front end of the refrigerator 1 is fitted with a cover plate 103 via a hinge. A handle is installed on the cover plate 103. The hinge connection allows the cover plate 103 to be opened and closed, making it convenient for operators to hang beef on the hook 303 for cold storage and sterilization, and to hold the handle to open the cover plate 103 and take out the beef after processing.

[0044] Two connecting frames 304 are provided, and the two connecting frames 304 are symmetrically distributed at equal intervals relative to the rotating shaft 305. The two symmetrically distributed connecting frames 304 can increase the hanging position and ensure that the beef hanging on the hook 303 maintains a stable hanging state during cold storage and sterilization, avoiding the beef from shaking or tilting due to uneven force. The evenly distributed connecting frames 304 allow the hook 303 to adjust the position and angle of the beef more smoothly during rotation (achieved by the second drive motor 302 driving the rotating shaft 305), which is conducive to the ultraviolet lamp 102 irradiating and sterilizing the beef from multiple angles, eliminating sterilization dead spots and improving the sterilization effect.

[0045] A connecting block 307 is welded onto the hook 303. The connecting block 307 is fitted inside the fixing block 306, allowing personnel to rotate the hook 303 to adjust the hanging angle according to the actual needs of beef hanging.

[0046] Example 2

[0047] To avoid inconvenience when inserting and removing beef, the beef can be unfolded during placement and removal, for example, such as... Figures 1 to 5 As shown, this utility model also includes:

[0048] A mounting bracket 3 is installed on the second drive motor 302. A guide block 301 is welded onto the mounting bracket 3. The guide block 301 is slidably sleeved on the limiting rod 201. The guide block 301 is threaded onto the lead screw 203. When the first drive motor 202 drives the lead screw 203 to rotate, the guide block 301 is threaded onto the lead screw 203 and slidably sleeved on the limiting rod 201. The limiting rod 201 plays a guiding and limiting role, which can ensure that the guide block 301 moves smoothly along the axial direction of the lead screw 203, thereby driving the mounting bracket 3, the second drive motor 302, and the hook 303 to move horizontally inside the refrigerator 1. In this way, after the beef sterilization process is completed, the hook 303 suspending the beef can be moved to a position near the cover 103 of the refrigerator 1 by controlling the first drive motor 202. This allows operators to directly retrieve the beef from the opening of the refrigerator 1 without having to reach deep into the refrigerator, greatly improving the convenience and efficiency of beef handling. It also reduces the time operators spend in contact with the low-temperature environment, lowering the risk of them getting cold. Furthermore, when placing the beef, the hook 303 can be moved to a suitable position for easy hanging, enhancing the convenience and user-friendliness of the entire beef processing procedure.

[0049] Working principle:

[0050] Beef placement: The operator holds the handle to open the cover 103, which is hinged to the front of the refrigerator 1, and then hangs the beef on the hook 303.

[0051] Component Installation and Guiding: A guide block 301 is welded to the mounting bracket 3 mounted on the second drive motor 302. The guide block 301 is slidably sleeved on the limiting rod 201 and threadedly mounted on the lead screw 203. When the first drive motor 202 drives the lead screw 203 to rotate, due to the guiding and limiting effect of the limiting rod 201, the guide block 301 can move smoothly along the axial direction of the lead screw 203, thereby driving the mounting bracket 3, the second drive motor 302, and the hook 303 to move horizontally within the refrigerator 1. When placing beef, the hook 303 can be moved to a suitable position by controlling the first drive motor 202 for easy hanging.

[0052] Sterilization treatment: Two symmetrically distributed connecting frames 304 with equidistant rotating shafts 305 ensure that the beef hanging on the hooks 303 maintains a stable hanging state during the cold storage sterilization process. The output end of the second drive motor 302 drives the connecting frames 304 and hooks 303 to rotate through the rotating shafts 305, so that the position and angle of the beef can be adjusted more smoothly. This allows the ultraviolet irradiation lamps 102 installed in the refrigerator 1 to irradiate and sterilize the beef from multiple angles, eliminating sterilization dead spots and improving the sterilization effect.

[0053] Beef Removal: After the beef has been sterilized, the first drive motor 202 is controlled to move the hook 303, which is holding the beef, to a position near the cover 103 of the refrigerator 1. The operator can then use the handle to open the cover 103 and directly remove the beef from the opening of the refrigerator 1 without having to reach deep into the refrigerator 1. This reduces the time the operator is in contact with the low-temperature environment and lowers the risk of the operator getting frozen.
