Description

Technical Field

[0001] This utility model relates to the field of frog aquatic product preservation technology, specifically to a frog refrigeration and preservation device. Background Technology

[0002] With the continuous improvement of people's living standards, consumers' demand for high-quality aquatic products is increasing, especially fish, frogs, and shrimp, which are popular due to their rich nutrition and delicious taste. Among them, frogs, with their tender meat and unique flavor, have become a best-selling product in the market. However, frog products are extremely prone to spoilage after being caught or processed, seriously affecting their commercial value and food safety. Therefore, in order to extend their shelf life and maintain their original quality, it is particularly important to develop an efficient and practical refrigeration and preservation device for frogs.

[0003] Existing refrigeration and preservation devices for frogs typically store processed frog products together in a static state, making them prone to freezing and difficult to remove. Furthermore, frog products processed at different times can easily become mixed up. For better preservation and consumption, frogs should be stored in a low-temperature environment of 0-4℃ for short periods, using layered storage or sealed packaging to prevent moisture loss or cross-contamination. This refrigeration method not only maintains the frogs' tender texture but also effectively prevents cross-contamination, ensuring product quality. If pre-processed frog products are stored or used together with later-processed products, prolonged storage may lead to a decline in the quality of the pre-processed products, affecting their taste and nutritional value.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a frog refrigeration and preservation device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A frog refrigeration and preservation device includes: a refrigeration box; support legs disposed at the four corners of the bottom of the refrigeration box; a door hinged to the top of the refrigeration box; a material stacking assembly disposed inside the refrigeration box for placing frog aquatic products; several preservation trays disposed inside the material stacking assembly; several hook assemblies disposed at the inner top of the preservation trays for hanging frog aquatic products; a condenser coil wound inside the refrigeration box for maintaining the refrigeration box between 0-4 degrees Celsius; a temperature sensor disposed on the inner wall of the top of the refrigeration box; a feeding port disposed on one side wall of the refrigeration box and cooperating with the material stacking assembly; a closing door hinged to one end of the feeding port; a control panel disposed on one side wall of the refrigeration box and located above the feeding port; and several strip plates cooperating with the hook assemblies disposed on the top of the preservation trays.

[0008] Furthermore, to prevent pre-processed and post-processed frog products from being mixed together for refrigeration and preservation under the action of the material stacking component, frog products requiring refrigeration and preservation can be stored and used in layers. This avoids the quality degradation of pre-processed frog products after long-term storage, affecting their taste and nutritional value, thereby improving the preservation efficiency of the frog refrigeration and preservation device. The material stacking component includes a placement component installed inside the refrigeration box. A driving component that cooperates with a preservation tray is installed through the bottom of the placement component, and the driving component passes through the refrigeration box and the placement component sequentially from bottom to top. The placement component includes a fixing plate installed at the bottom of the refrigeration box. The top two ends of the fixing plate are symmetrically equipped with mounting brackets, and the inner walls of the two sides of the mounting brackets are provided with... Several limiting rods are provided, and placement blocks are symmetrically fitted on the outer circumference of each limiting rod. A fixing post that cooperates with the placement block is provided at the top of the end of the mounting frame between the inner walls on both sides and away from the limiting rod. Limiting rings are provided on both sides of the placement block and on the outer circumference of the limiting rod. The placement block and the limiting rod are movably connected, and the placement block has an inverted triangular structure. A placement groove that cooperates with the preservation tray is opened at the top of the placement block and near the preservation tray. A limiting baffle that cooperates with the preservation tray is symmetrically provided at the top of one side of the fixing plate. A feeding plate that cooperates with the feeding port is provided at the top of the other side of the fixing plate. The driving component includes a hydraulic rod that passes through the bottom of the refrigerator. The telescopic end of the hydraulic rod passes through the refrigerator and the fixing plate from bottom to top and is connected to a push plate that cooperates with the preservation tray.

[0009] Furthermore, to enable the hanging and preservation of frog-like aquatic products requiring refrigeration and preservation through the hook assembly, preventing them from piling up and freezing on the refrigeration device and becoming difficult to remove, thus improving the storage and retrieval efficiency of the frog-like refrigeration and preservation device, the hook assembly includes a fixing member located at the bottom of the strip plate. A movable member is inserted through the top of the fixing member. The fixing member includes a U-shaped frame located at the bottom of the strip plate, with an opening on one side of the U-shaped frame. A chamber is located at the top of the U-shaped frame, with symmetrical openings at the bottom of the chamber. A limiting slot is located on one side wall of the bottom of the U-shaped frame below the opening. The movable member includes cylinders symmetrically arranged at the bottom of the chamber. Springs are fitted around the circumference of each cylinder. A movable frame is connected to the top of each spring. A limiting block that mates with the limiting slot is located on one side wall of the bottom of the movable frame. Several limiting protrusions are located at the bottom of the movable frame, and hooks that mate with the frog-like aquatic products are fitted around the limiting protrusions.

Through the coordinated action of the refrigeration box, the material stacking component, the preservation tray, the hook component, the condenser tube, the temperature sensor, the feeding port, and the control panel, it can not only prevent pre-processed and post-processed frog products from being mixed together for refrigeration and preservation, but also allow frog products requiring refrigeration and preservation to be stored and used in layers. This avoids the quality degradation of pre-processed frog products after long-term storage, which would affect their taste and nutritional value. At the same time, it can also enable the hanging storage of frog products requiring refrigeration and preservation, avoiding the phenomenon of frog products being piled up together and easily frozen on the refrigeration and preservation device, making them difficult to remove. This improves the preservation efficiency and storage efficiency of the frog refrigeration and preservation device.

[0012] 2. By setting up the material stacking component, the frog aquatic products that are processed first and processed later can be prevented from being mixed together for refrigeration and preservation. This allows the frog aquatic products that need refrigeration and preservation to be stored and used in layers, avoiding the decline in quality of the frog aquatic products that are processed first after long-term storage, which would affect their taste and nutritional value. This improves the preservation efficiency of the frog refrigeration and preservation device.

[0013] 3. By setting up a hook assembly, frog and aquatic products that require refrigeration and preservation can be hung and stored, avoiding the phenomenon that frog and aquatic products are piled up together and easily frozen on the refrigeration and preservation device, making them difficult to remove, thereby improving the storage and retrieval efficiency of the frog refrigeration and preservation device.

Detailed Implementation

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a frog refrigeration and preservation device is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-10As shown, the frog refrigeration and preservation device according to an embodiment of the present invention includes: a refrigerator box 1; support legs 2, disposed at the four corners of the bottom of the refrigerator box 1; a door 3, hinged to the top of the refrigerator box 1; in specific application, a sealing strip is provided between the door 3 and the refrigerator box 1 (not shown in the figure); a material stacking assembly 4, disposed inside the refrigerator box 1, used for placing frog aquatic products; a preservation tray 5, disposed inside the material stacking assembly 4, and several preservation trays 5 are provided; a hook assembly 6, disposed at the inner top of the preservation tray 5, and several hook assemblies 6 are provided, used for hanging frog aquatic products; and a condenser pipe 7, wound inside the refrigerator box 1, used to maintain the refrigerator box 1 at 0-4°C. The temperature range is between 0 and 4 degrees Celsius. In practical applications, the temperature for short-term cold storage of frogs is usually controlled between 0 and 4 degrees Celsius to maintain the freshness of frog aquatic products. If long-term freezing is required, the storage temperature of frog aquatic products needs to be controlled below -18 degrees Celsius. Temperature sensor 8 is set on the inner wall of the top of the refrigerator 1. Feeding port 9 is opened on one side wall of the refrigerator 1 and cooperates with the material stacking assembly 4. Closing door 10 is hinged to one end of the feeding port 9. In practical applications, a sealing strip is set between the closing door 10 and the feeding port 9, which is not shown in the figure. Control panel 11 is set on one side wall of the refrigerator 1 and located on top of the feeding port 9. The top of the preservation tray 5 is provided with several strip plates 501 that cooperate with the hook assembly 6.

[0030] Furthermore, the frog refrigeration and preservation device of this utility model can not only store and preserve frog aquatic products, but also adapt to other types of aquatic products such as fish and shrimp by changing the parameters of the refrigeration box 1, thereby improving the efficiency and freshness of other types of aquatic products during storage and retrieval.

[0031] It should be explained that the refrigerator 1 also includes components such as a compressor, evaporator, and condenser to ensure that the temperature is high enough to keep the frog aquatic products fresh. The condenser tube 7 is usually made of glass. The basic structure of the condenser tube 7 includes an inner tube and an outer tube. The inner tube is used to pass steam, while the outer tube is used to circulate cooling water. All of the above are existing technologies and will not be described in detail here.

[0032] In practical applications, the control panel 11 is equipped with a human-machine interface and a PLC programmable logic controller. The human-machine interface is the interaction interface between the operator and the automation system. Its main function is to display the real-time operating status and the input of control commands. The PLC is used to execute specific control tasks, such as switching, controlling the extension speed and extension length of the hydraulic rod 4021, or acquiring and processing sensor signals.

[0033] In one embodiment, the material stacking assembly 4 includes a placement member 401 disposed inside the refrigerator box 1. A driving member 402, which cooperates with the preservation tray 5, is disposed through the bottom of the placement member 401. The driving member 402 passes through the refrigerator box 1 and the placement member 401 sequentially from bottom to top. The placement member 401 includes a fixing plate 4011 disposed at the bottom of the refrigerator box 1. Mounting brackets 4012 are symmetrically disposed at both ends of the top of the fixing plate 4011. Several limiting rods 4013 are provided between the inner walls of both sides, and placement blocks 4014 are symmetrically fitted around the outer circumference of each limiting rod 4013; a fixing post 4015 is provided at the top of the end of the mounting bracket 4012 away from the limiting rods 4013 between the inner walls of both sides to cooperate with the placement block 4014; limiting rings 4016 are provided on both sides of the placement block 4014 and on the outer circumference of the limiting rods 4013; the placement block 4014 is movably connected to the limiting rods 4013, and the placement block 4014 is symmetrically fitted around the outer circumference of the limiting rods 4013. 4 is an inverted triangular structure. The top of the placement block 4014, near the end close to the preservation tray 5, has a placement groove 4017 that mates with the preservation tray 5. A limiting baffle 4018 mates with the preservation tray 5 is symmetrically arranged on one side of the top of the fixing plate 4011. A feeding plate 4019 mates with the feeding port 9 is arranged on the other side of the fixing plate 4011. The driving component 402 includes a hydraulic rod 4021 that penetrates the bottom of the refrigerator 1. The telescopic ends of the hydraulic rod 4021 extend from bottom to top... The refrigerated box 1 and the fixing plate 4011 are connected to a push plate 4022 that cooperates with the preservation tray 5. Under the action of the material stacking component 4, the pre-processed frog aquatic products and the post-processed frog aquatic products can be prevented from being mixed together for refrigeration and preservation. This allows the frog aquatic products that need refrigeration and preservation to be stored and used in layers, avoiding the decline in the quality of the pre-processed frog aquatic products after long-term storage, which would affect their taste and nutritional value. This improves the preservation efficiency of the frog refrigeration and preservation device.

[0034] The specific working principle of the material stacking component 4 is as follows: The preservation tray 5, on which frog aquatic products are suspended, is fed onto the feeding plate 4019 through the feeding port 9. Then, under the limiting action of the feeding plate 4019, the preservation tray 5 is pushed into the refrigerator 1. When one end of the preservation tray 5 contacts the limiting baffle 4018, the pushing stops. The hydraulic rod 4021 is extended through the control panel 11. Under the action of the hydraulic rod 4021, the pushing plate 4022 moves upward. The pushing plate 4022 pushes the preservation tray 5 on the feeding plate 4019 upward until both ends of the preservation tray 5 contact the bottom of the placement block 4014. It continues to move upward, and the placement block 4014 is pushed to make an arc motion around the limiting rod 4013. When the rotation of the placement block 4014 can no longer contact the upward-moving preservation tray 5, the hydraulic rod 4021 is shortened. Under the action of the hydraulic rod 4021, the push plate 4022 is driven back to its original position. At the same time, under its own weight and the limiting action of the fixing column 4015, the top of the placement block 4014 returns to the horizontal position. Under the action of gravity, both ends of the preservation tray 5 will be placed in the placement groove 4017. Then the operator can place the next preservation tray 5 with frog aquatic products. Then, the preservation trays 5 are placed in the same way as above. When all the placement blocks 4014 in the material stacking assembly 4 have preservation trays 5, the closing door 10 can be closed.

[0035] In one embodiment, the hook assembly 6 includes a fixing member 601 disposed at the bottom end of the strip plate 501, a movable member 602 inserted through the inner top of the fixing member 601, the fixing member 601 including a U-shaped frame 6011 disposed at the bottom end of the strip plate 501, an opening 6012 on one side of the U-shaped frame 6011, a cavity 6013 disposed at the top inside the U-shaped frame 6011, symmetrical openings 6014 at the bottom inside the cavity 6013, and a limiting groove 6015 disposed on one side wall of the bottom inside the U-shaped frame 6011 below the opening 6012, the movable member 602 including cylinders 6021 symmetrically disposed at the bottom inside the cavity 6013. Springs 6022 are fitted around the circumference of column 6021. A movable frame 6023 is connected to the top of the springs 6022. A limiting block 6024 that cooperates with the limiting slot 6015 is provided on the bottom side wall of the movable frame 6023. Several limiting protrusions 6025 are provided at the inner bottom end of the movable frame 6023. Hooks 6026 that cooperate with frog aquatic products are fitted around the limiting protrusions 6025. Under the action of the hook assembly 6, frog aquatic products that need to be refrigerated and preserved can be hung and preserved, avoiding the phenomenon that frog aquatic products are piled up together and easily frozen on the refrigeration and preservation device, making them difficult to remove. This improves the storage and retrieval efficiency of the frog refrigeration and preservation device.

[0036] The specific working principle of the hook assembly 6 is as follows: When it is necessary to hang frog aquatic products, the frog aquatic products are hooked by the hook 6026, and then the hook 6026 is hung on the limiting protrusion 6025. When the top of the hook 6026 contacts the limiting protrusion 6025, it is released. Under the action of gravity, the moving frame 6023 moves downward, thereby closing one side of the moving frame 6023 to the opening 6012. When it is necessary to remove the frog aquatic products, the operator only needs to lift the hook 6026 upward. At this time, the hook 6026 leaves the moving frame 6023. Then, under the action of the spring 6022, one side of the moving frame 6023 leaves the opening 6012 and rises, so that the frog aquatic products can be removed.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In practical application, firstly, the frog and aquatic products requiring refrigeration are hung evenly in the preservation trays 5 using the hook assembly 6. Then, the preservation trays 5 with the frog and aquatic products are fed to the stacking assembly 4 through the feeding port 9. The closing door 10 is closed, and the stacking assembly 4 is started via the control panel, so that the suspended frog and aquatic products are evenly layered in the refrigerator 1. With the cooperation of the external compressor and condenser 7, the refrigeration environment inside the refrigerator 1 is ensured, maintaining the freshness of the frog and aquatic products inside. When it is necessary to remove the frog and aquatic products, the door 3 is opened, and then the preservation trays 5 with the frog and aquatic products hanging in the stacking assembly 4 are removed. Once the frog products are removed from the hook assembly 6, they can be used. During the storage and retrieval of frog products, the temperature inside the refrigerator 1 will inevitably change. Therefore, when the temperature sensor 8 detects that the temperature inside the refrigerator 1 exceeds the set normal range, such as being too high or too low, the temperature sensor 8 will immediately send an alarm signal to the control panel 11. After receiving the abnormal temperature signal, the control panel 11 will control the refrigeration system, namely the compressor, evaporator, condenser and other components, to start and stop the corresponding refrigeration measures to restore the normal temperature range and maintain the constant temperature inside the refrigerator 1, thereby improving the preservation effect of the frog refrigeration and preservation device.
