Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and specifically to a meat refrigeration and preservation device that integrates meat stringing function. Background Technology

[0002] In the barbecue and meat skewer food processing industry, the refrigeration and preservation of meat ingredients and the skewering process are two core steps, and their synergy directly affects food safety, production efficiency, and product quality. Currently, most existing meat refrigeration devices on the market have relatively simple functions, possessing only basic low-temperature refrigeration and preservation capabilities. They are mainly used to store unprocessed raw meat or processed finished meat skewers and are not specifically designed for the special characteristics of skewered meat, thus failing to meet the refrigeration and storage requirements of skewered meat.

[0003] In actual production, skewered meat inevitably experiences blood seepage and dripping during refrigeration, a problem exacerbated by both the skewering process and the refrigeration environment. On one hand, the piercing action of the skewers directly damages the muscle fiber bundles and cell membrane structure of the meat, significantly reducing its water retention capacity. The tissue fluid (i.e., blood, mainly composed of myoglobin, water, and a small amount of nutrients) originally locked within the muscle cells continuously seeps out through the piercing channels and gaps in the meat. Simultaneously, the squeezing and high-speed piercing during skewering further tears the muscle tissue, expanding the bleeding channels and significantly increasing the amount of blood seepage.

[0004] On the other hand, temperature fluctuations in the refrigerated environment can further exacerbate blood seepage. Existing refrigeration equipment has limited temperature control precision, and frequent opening and closing of cabinet doors and starting and stopping of the refrigeration system can easily cause temperature fluctuations inside the cabinet. Repeated temperature changes can cause the free water between meat cells to form tiny ice crystals. The melting and regeneration of these ice crystals will continuously damage the structure of meat cells, leading to more tissue fluid seepage and the formation of additional blood.

[0005] Dripped blood can cause a series of serious problems for the refrigerated storage of meat. First, blood is rich in nutrients such as protein and water, and even under low-temperature refrigeration, it cannot completely inhibit the growth of pathogenic bacteria. Dripped blood can form a breeding ground for bacteria on the inner liner and shelf surfaces of the refrigerator, not only contaminating the meat skewers themselves but also causing cross-contamination between different batches and types of meat skewers, posing a significant food safety hazard. Second, blood is corrosive. Long-term dripping and adhesion to the inner liner of the refrigerator (especially those made of ordinary steel plates) will gradually corrode the coating and substrate, leading to rust and damage, shortening the lifespan of the refrigeration unit, and increasing equipment maintenance costs. Third, if dripped blood is not cleaned up promptly, it will produce a putrid odor inside the refrigerator. This odor will adhere to the surface of the meat skewers, affecting their flavor and quality, while also polluting the internal environment of the refrigerator and increasing the difficulty of cleaning. Summary of the Invention

[0006] The purpose of this invention is to provide a meat refrigeration and preservation device that integrates meat skewering function, and to solve the following technical problems: existing meat refrigeration devices have single functions and lack special design for the characteristics of blood seepage from skewered meat. They cannot effectively solve problems such as the proliferation of pathogenic bacteria, cross-contamination of the cabinet, and corrosion of the inner liner caused by blood dripping. They are difficult to meet the high-quality and high-safety requirements of barbecue catering and meat skewer food processing industries for refrigeration and preservation of skewered meat.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A meat refrigeration and preservation device with integrated meat skewering function includes a base and a refrigerator on the base. A movable mounting rack is provided on the base, and a meat skewering mechanism is installed on the mounting rack. The refrigerator contains a water collection tank, and a draining support plate is installed above the water collection tank. The water collection tank is a rectangular structure with an open top. A lifting plate is installed on the bottom wall of the water collection tank, and the draining support plate is placed on top of the lifting plate. The top of the inner walls on both sides of the water collection tank is fixed with a U-shaped plate. A sliding plate is slidably connected inside the U-shaped plate. A partition is fixed at one end of the two sliding plates that are close to each other. An installation block is inserted into the top of the partition. A connecting rod is rotatably connected to the top of the installation block. One end of the connecting rod is rotatably installed on the lower surface of the drain load-bearing plate.

[0009] As a further aspect of the present invention: the drain bearing plate is made of food-grade stainless steel, and multiple drain holes are arranged in an array on the drain bearing plate, and a water-blocking strip is provided on the upper surface of the drain bearing plate.

[0010] As a further aspect of the present invention: inclined guide plates are provided on both sides of the lower surface of the drainage load-bearing plate.

[0011] As a further aspect of the present invention: the lifting plate includes a hollow plate fixed inside the water collection tank, a first spring is connected inside the hollow plate, and one end of the first spring is connected to a movable plate.

[0012] As a further aspect of the present invention: two lifting rods are installed on the upper surface of the U-shaped plate. Each lifting rod includes a hollow rod fixed to the U-shaped plate. A second spring is connected inside the hollow rod. One end of the second spring is connected to a movable rod. The top of the movable rod is in contact with the drainage load-bearing plate.

[0013] As a further aspect of the present invention: a plug-in block is fixed to the bottom of the mounting block, and a plug-in groove matching the size of the plug-in block is provided on the partition plate.

[0014] As a further aspect of the present invention: the meat skewering mechanism includes two support plates fixed on the mounting frame, a conveyor belt is installed between the two support plates, a mounting plate is fixed on one side of one of the support plates, a skewering machine and two guide rods are mounted on the mounting plate, a top plate is fixed on the top of the two guide rods, a positioning frame is movably mounted on the two guide rods, a cylinder is mounted on the top plate, and the output shaft of the cylinder is fixedly connected to the positioning frame.

[0015] The beneficial effects of this invention are: (1) By setting up a water collection tank, this invention can accurately collect the blood dripping from the meat after skewering, preventing the blood from dripping directly onto the inner liner and shelf surface of the refrigerator. This eliminates the problem of cross-contamination of meat skewers caused by blood as a breeding ground for pathogenic bacteria, thus meeting food safety production standards. At the same time, it avoids corrosion of the inner liner of the refrigerator caused by long-term blood adhesion, extends the service life of the device, and reduces equipment maintenance costs. The blood collects between the cavity formed by the two partitions, avoiding large-area contact between the blood and air, reducing the putrid odor caused by the oxidation and deterioration of the blood, preventing the odor from adsorbing onto the surface of the meat skewers, and ensuring the flavor and quality of the meat skewers. (2) In this invention, the distance between the two partitions can be adaptively changed according to the weight of the meat skewers, forming a dynamically adjustable blood collection cavity: when the weight of the meat skewers is small, the distance between the partitions is close, forming a small collection cavity. At this time, the blood can quickly gather, the liquid surface is highly concentrated, and the contact area with air is small. Even in the low temperature environment of refrigeration, the antibacterial effect can be further improved and the reproduction of pathogenic bacteria can be reduced. When the weight of the meat skewers is heavy and the amount of blood seepage is large, the distance between the partitions automatically increases, and the volume of the collection cavity expands synchronously. It can fully accommodate a large amount of blood, effectively prevent blood from overflowing, avoid secondary pollution, and achieve a precise match between "meat quantity and blood collection volume". It can adapt to the needs of different meat skewer storage quantities without manual intervention. (3) The adaptive cavity design of the present invention can avoid unnecessary space occupation: when the weight of the meat skewers is small, the small volume of the collection cavity will not occupy too much effective refrigeration space in the refrigerator, making the effective refrigeration volume in the refrigerator more compact, and the refrigeration system can quickly achieve low temperature control in the refrigerator, reduce the compressor start-stop frequency, and reduce equipment energy consumption; when the weight of the meat skewers is large, the cavity automatically expands, only occupying extra space when needed, without the need to reserve redundant space for a long time. (4) The blood collection chamber of the present invention is adjusted by the weight of the meat skewers themselves. There is no need to set up additional electrical control components such as motors and sensors. The pure mechanical structure design makes it highly stable in operation and not prone to failure. It is suitable for long-term use in cold storage and low temperature environments. At the same time, the water collection tank and partition structure are easy to disassemble and clean, and can quickly clean up the collected blood and residual stains, reduce the intensity of manual cleaning labor, and further reduce the operating and maintenance costs of enterprises.

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual size and shape of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0020] 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.

[0021] Please see Figures 1 to 9 As shown, this invention is a meat refrigeration and preservation device with integrated meat skewering function, including a base 1 and a refrigerator 2 located on the base 1. A movable mounting frame 3 is provided on the base 1, and a meat skewering mechanism 4 is installed on the mounting frame 3. A water collection tank 5 is placed inside the refrigerator 2, and a draining support plate 6 is provided above the water collection tank 5. The water collection tank 5 is a rectangular structure with an open top. A lifting plate 8 is provided on the bottom wall of the water collection tank 5, and the draining support plate 6 is placed on top of the lifting plate 8. U-shaped plates 13 are fixed to the top of the inner walls on both sides of the water collection tank 5, and sliding plates are slidably connected inside the U-shaped plates 13. 14. Two sliding plates 14 are each fixed with a partition 12 at their adjacent ends. A mounting block 15 is inserted into the top of the partition 12, and a connecting rod 16 is rotatably connected to the top of the mounting block 15. One end of the connecting rod 16 is rotatably mounted on the lower surface of the drain support plate 6. The pre-prepared meat products are placed on the skewering mechanism 4, which conveys and skewers the meat products. The operator immediately places the skewered meat products into the refrigerator 2 for refrigeration and preservation. The skewered meat products are evenly arranged on the drain support plate 6, which will automatically lower according to the weight of the meat. When less meat is placed in the tank, the position of the draining support plate 6 and the two partitions 12 remain largely unchanged. Blood from the meat drips into the space between the two partitions 12 in the collection tank 5. At this point, the cavity formed between the two partitions 12 is at its smallest, allowing the blood to quickly collect. The liquid level is highly concentrated, and the surface area in contact with air is small. Under low-temperature refrigeration conditions, this further enhances the antibacterial effect and reduces the growth of pathogenic bacteria. When the meat skewers become heavier, the draining support plate 6 descends, causing the two partitions 12 to move further apart via the connecting rod 16. The distance between the partitions 12 automatically increases, and the volume of the collection cavity expands accordingly. The meat skewers themselves are heavy and produce a corresponding amount of blood, which can be fully contained, effectively preventing blood from overflowing and avoiding secondary contamination. This achieves a precise match between the amount of meat and the blood collection volume, and can adapt to the needs of different meat skewer storage volumes without manual intervention. At the same time, due to the presence of the U-shaped plate 13 and the sliding plate 14, the space on the side away from the two partitions 12 will not allow cold air to enter. This will not occupy too much effective refrigeration space in the refrigerator 2, making the effective refrigeration volume inside the refrigerator more compact. The refrigeration system can quickly achieve low temperature control inside the refrigerator, reduce the frequency of compressor start-stop, and reduce equipment energy consumption.

[0022] See Figure 2 and Figure 3 The drainage support plate 6 is made of food-grade stainless steel. Multiple drainage holes 9 are arranged in an array on the drainage support plate 6. A water-blocking strip 10 is provided on the upper surface of the drainage support plate 6. The cross-section of the drainage holes 9 is designed in a conical shape to prevent refrigeration ice from clogging the holes. The water-blocking strip 10 prevents blood from overflowing.

[0023] See Figure 3 and Figure 4Inclined guide plates 11 are provided on both sides of the lower surface of the drainage load-bearing plate 6; the guide plates 11 can make all the drained blood water collect between the two partition plates 12.

[0024] See Figure 2 , Figure 6 and Figure 7 The lifting plate 8 includes a hollow plate 801 fixed inside the water collection tank 5. A first spring 802 is connected inside the hollow plate 801, and a movable plate 803 is connected to one end of the first spring 802. Two lifting rods 7 are installed on the upper surface of the U-shaped plate 13. The lifting rods 7 include hollow rods 701 fixed on the U-shaped plate 13. A second spring 702 is connected inside the hollow rods 701, and a movable rod 703 is connected to one end of the second spring 702. The top of the movable rod 703 contacts the draining load-bearing plate 6. The lifting plate 8 and the multiple lifting rods 7 together support the draining load-bearing plate 6, ensuring its stability and enabling the draining load-bearing plate 6 to automatically descend according to the weight of the meat products it receives.

[0025] See Figure 2 and 8 The bottom of the mounting block 15 is fixed with a plug-in block 17. The partition 12 has a plug-in groove 18 that matches the size of the plug-in block 17. The mounting block 15 and the partition 12 are connected by plugging. When it is necessary to clean the collected blood water, simply remove the drain load-bearing plate 6 from the cabinet first, and then recycle the blood water in the water collection tank 5. Alternatively, a drain pipe can be connected to the water collection tank 5 to drain the blood water first, and then clean and disinfect the water collection tank 5.

[0026] See Figure 1 and Figure 9 The meat skewering mechanism 4 includes two support plates 401 fixed on the mounting frame 3. A conveyor belt 402 is installed between the two support plates 401. A mounting plate 403 is fixed to one side of one of the support plates 401. A skewering machine 404 and two guide rods 405 are mounted on the mounting plate 403. A top plate 406 is fixed to the top of the two guide rods 405. A positioning frame 407 is movably mounted on the two guide rods 405. A cylinder 408 is mounted on the top plate 406. The output shaft of the cylinder 408 is fixedly connected to the positioning frame 407. The prepared... The meat products are placed on the conveyor belt 402, which moves the meat products intermittently. When the meat products move directly under the positioning frame 407, the cylinder 408 drives the positioning frame 407 to descend and fix the meat products. The skewering machine 404 then inserts bamboo skewers into the meat products. Subsequently, the cylinder 408 drives the positioning frame 407 to reset, and the conveyor belt 402 sends the skewered meat products away to perform the next skewering operation. It is worth noting that the skewering machine 404 and the positioning frame 407 are existing technologies, and their specific structures will not be described in detail here.

[0027] The working principle of this invention is as follows: First, the pre-prepared meat products are placed on the conveyor belt 402 of the meat skewering mechanism 4. The conveyor belt 402 drives the meat products to move intermittently. When the meat products move to the position frame 407, the cylinder 408 on the top plate 406 drives the position frame 407 to descend along the two guide rods 405 to accurately fix the meat products. Then, the skewering machine 404 inserts bamboo skewers into the meat products to complete the skewering operation. After the skewering is completed, the cylinder 408 drives the position frame 407 to reset, and the conveyor belt 402 sends the skewered meat away so that the next continuous skewering operation can be carried out. After skewering, the operator immediately and evenly places the meat skewers on the draining support plate 6. The guide plate 11 collects all the blood seeping from the meat skewers into the water collection tank 5 between the two partitions 12, ensuring that the blood does not spill or contaminate the inside of the refrigerator 2. The draining support plate 6 is supported by the lifting plate 8 and multiple lifting rods 7. When the weight of the placed meat skewers is small, the pressure on the draining support plate 6 is small, and its position does not change significantly. Then, the connecting rod 16 moves the two partitions 12 to maintain the original distance. At this time, a gap is formed between the two partitions 12. The cavity space is minimal, allowing the blood seeping from the meat skewers to quickly gather. The liquid surface is highly concentrated with a small contact area with air, which further enhances the antibacterial effect and reduces the reproduction of pathogenic bacteria in the low-temperature environment of the refrigerator 2. At the same time, due to the cooperation of the U-shaped plate 13 and the sliding plate 14, no cold air will enter the space on the side where the two partitions 12 are far apart, and it will not occupy too much effective refrigeration space of the refrigerator 2, making the effective refrigeration volume inside the cabinet more compact. The refrigeration system can quickly achieve low-temperature control inside the cabinet, reduce the frequency of compressor start-stop, and reduce equipment energy consumption. When the weight of the meat skewers is high, the pressure generated by the meat skewers will cause the drain support plate 6 to descend. During the descent, the connecting rod 16 will drive the two partitions 12 to move away from each other, and the distance between the partitions 12 will automatically increase. The volume of the collection cavity will also expand at the same time. When the weight of the meat skewers is high, the amount of blood seeping out will be correspondingly greater. The expanded cavity can fully accommodate a large amount of blood, effectively preventing blood from overflowing and avoiding secondary pollution. This achieves a precise match between the amount of meat and the blood collection volume, and can adapt to the needs of different meat skewer storage volumes without manual intervention. When it is necessary to clean the blood water collected in the water collection tank 5, the drain support plate 6 can be directly removed from the refrigerator 2, and then the blood water in the water collection tank 5 can be recycled.

[0028] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
