Description

Technical Field

[0001] This utility model relates to the field of fresh meat transportation and preservation technology, specifically a fresh meat transportation and preservation device. Background Technology

[0002] Fresh meat transport preservation equipment is a device specifically designed to maintain the freshness of fresh meat during transportation. In the transportation of fresh meat, a low temperature environment of 0-4℃ is key to maintaining meat quality and preventing spoilage.

[0003] A search revealed a cold chain transportation and preservation device for meat products with publication number CN214223486U. By movably connecting an ultraviolet germicidal lamp to a connecting block, it has the advantage of sterilizing the meat products placed inside, solving the problem of meat spoilage and economic losses caused by bacterial growth during transportation. In addition, the placement plate is movably connected to the outer shell of the box, which has the advantage of placing the meat products in layers, solving the problem of meat products being frozen together at low temperatures and unable to be separated.

[0004] When in use, the above-mentioned device allows for the separate storage of meat by placing a shelf inside a professional insulated box with active cooling function. Although such insulated boxes can accurately control the temperature, the equipment cost is high. It needs to integrate complex components such as Danfoss SC18CM compressor (single unit weight of about 8.5kg) and Siemens RWD68 temperature control system (total weight of about 2.2kg including sensors and control modules). The core temperature control components alone weigh more than 10kg. After adding the box support structure, the weight of the whole machine generally reaches 35-50kg, which is significantly increased compared to ordinary foam insulated boxes. The excessive weight will directly occupy the effective load space of the delivery vehicle. At the same time, the maintenance cost of such insulated boxes is also high, such as annual maintenance of the compressor and calibration of the temperature control system. While simple containers such as foam insulated boxes and ordinary plastic insulated boxes are low-cost and lightweight, they are unsuitable for transporting fresh pork (which needs to be stored at 0-4℃, typically for only 2-3 days; beyond that, bacteria will slowly multiply, leading to deterioration of meat quality and decreased freshness). The internal structure relies solely on the stacking of the insulated bags. During transport, vehicle starts and stops, and road bumps can easily cause the meat packaging to slide or tip over, potentially breaking the insulated bags and exposing the meat to the transport environment, causing contamination. Furthermore, these devices (plastic insulated boxes) often use ice packs for cooling. If pork is placed directly on the surface of the ice pack, the continuous release of cold energy can cause the local temperature of the pork to drop rapidly below 0℃, leading to the surface of the pork freezing and sticking to the ice pack. This damages the muscle fiber structure of the pork, significantly shortening its 72-degree length. The standard preservation time limit of 1 hour increases the risk of spoilage. If the pork is placed separately from the ice pack to avoid sticking, the temperature of the area away from the ice pack will be higher than that of the area near the ice pack. The suitable preservation range of 0-4℃ for some fresh pork means that the pork at higher places or away from the ice pack cannot maintain its freshness, further reducing the effective preservation time. Therefore, we propose a fresh meat transportation preservation device. Utility Model Content

[0005] The purpose of this invention is to provide a fresh meat transport and preservation device to solve the problems mentioned in the background art, such as poor compatibility between meat and ice packs and insufficient fixation of packaged meat during transport.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fresh meat transport and preservation device, comprising a preservation box, characterized in that: a cold air channel is provided on the inner wall of the preservation box, the cold air channel is used for cold air to circulate inside the preservation box, a placement drawer is slidably connected inside the cold air channel, a partition placement structure is assembled above the placement drawer, two circulation structures are symmetrically arranged on one side of the placement drawer, and an insulation cover is inserted into one side of the preservation box, the insulation cover is used to seal the opening of the preservation box.

[0007] The partitioned placement structure includes a U-shaped plate fixedly installed inside the food storage box, a baffle fixedly installed on the bottom wall of the U-shaped plate, and three sets of placement plates, with both ends of the placement plates fixedly connected to the U-shaped plate and the baffle respectively.

[0008] The inner wall of the U-shaped plate and the side wall of the baffle are provided with several ventilation holes, and four sliding grooves are provided on both sides of the inner wall of the U-shaped plate.

[0009] The inner wall of the chute is slidably connected with a flexible abutment plate, and the inner wall of the baffle is provided with a through groove that is at the same level as the chute.

[0010] The internal part of the through groove is rotatably connected to a lead screw, which is threaded to the middle of the flexible abutment plate. One end of the lead screw is fixedly connected to a turntable, which passes through the preservation box and extends to the outside of the preservation box.

[0011] The circulation structure includes a circular hole, a fan, and a filter screen. The fan is fixedly installed inside the circular hole, and the filter screen is fixedly connected to one side of the circular hole.

[0012] The inner wall of the drawer has through holes on both sides that connect to the cold air passage. The outer wall of the drawer is fixedly installed with a fixed base, and a hydraulic buffer rod is fixedly installed inside the fixed base. A spring is sleeved on the outside of the hydraulic buffer rod.

[0013] One end of the hydraulic buffer rod is fixedly connected to a plug rod, and the two ends of the spring are fixedly connected to the plug rod and the placement drawer, respectively. The inner wall of the heat-insulating cover is provided with a plug hole that matches the plug rod.

[0014] This utility model has at least the following beneficial effects: Through a partitioned design, the U-shaped plates, baffles, and multiple sets of placement plates provide independent carrying space for meat products, avoiding stacking and compression. At the same time, the flexible abutment plate works in conjunction with the screw and movable block to drive the rotating turntable to adjust the abutment position, forming a suitable limit for different sizes of meat products. This not only prevents the meat products from sliding or tipping over during transportation, but also reduces the risk of damage and contamination of the preservation bag from the source. In addition, the array of ventilation holes in the U-shaped plates and baffles can work with the cold air delivered by the circulation structure to ensure that the cold air is evenly distributed to each layer of meat products, providing a stable preservation environment for the meat products.

[0015] Through the design of the circulation structure, driven by a fan, and combined with the vents of the placement drawer and the cold air channel of the crisper, an active cold air circulation path is constructed. When the fan is running, the cold air generated by the ice packs on the placement drawer is actively transported to the cold air channel, and then diffused to each layer of meat area through the vents. This allows the cold air to evenly cover all the meat without direct contact with the ice packs, fundamentally solving the problems of sticking and uneven cold. At the same time, the filter screen in front of the fan can intercept dust and impurities, preventing contamination of the meat and effectively maintaining the appropriate preservation temperature for the meat, reducing the risk of spoilage caused by uneven cold.

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1 to 6 This utility model provides a technical solution: a fresh meat transport and preservation device, including a preservation box 1. A cold air channel 2 is formed on the inner wall of the preservation box 1, allowing cold air to circulate within the box. A placement drawer 3 is slidably connected inside the cold air channel 2 along its extension direction, for holding ice packs. A separating placement structure 4 is mounted above the placement drawer 3, for placing fresh meat and limiting the placement of the meat. A circulation structure 5 is mounted outside the placement drawer 3, for placing ice on the drawer 3. The cold air generated by the bag is transmitted to the inside of the preservation box 1 and distributed within it. A heat-insulating cover 6 is inserted horizontally at the front of the preservation box 1 to seal the front opening of the preservation box 1. A fixing sleeve that is compatible with the heat-insulating cover 6 is provided on the back of the preservation box 1. The insulation cover 6 can be fixed by inserting it into the fixing sleeve. The cold air channel 2 can create a circulation path for the cold air within the preservation box 1, preventing local accumulation of cold air, ensuring uniform temperature in all areas of the box, preventing fresh meat from spoiling due to local temperature differences, and extending the preservation time of the meat.

[0020] The partitioned placement structure 4 includes a U-shaped plate 41 fixedly installed inside the refrigerator 1, a baffle 42 fixedly installed on the inner bottom wall of the U-shaped plate 41, and three sets of placement plates 43. The three sets of placement plates 43 are equidistantly distributed along the height direction of the baffle 42, and the two ends of the placement plates 43 are fixedly connected to the inner wall of the U-shaped plate 41 and the side wall of the baffle 42, respectively. The placement plates 43 are used to hold fresh meat products.

[0021] Ventilation holes 44 are provided on the inner wall of the U-shaped plate 41 and the side wall of the baffle 42. Multiple sets of ventilation holes 44 are arranged in an array. The ventilation holes 44 are used to allow cold air to pass through the U-shaped plate 41 and the baffle 42. The inner wall of the U-shaped plate 41 has eight sliding grooves 411 on both sides. The eight sliding grooves 411 are divided into four groups along the height direction of the U-shaped plate 41. The ventilation holes 44 ensure that the cold air can pass smoothly through the U-shaped plate and the baffle 42 and enter each layer area, so that the cold air in the box is covered without dead corners, further improving the temperature uniformity.

[0022] The inner wall of the slide groove 411 is slidably connected with a flexible abutment plate 45. The inner wall of the baffle 42 is provided with a through groove that is at the same level as the slide groove 411. The four sets of slide grooves 411 can correspond to the placement plates 43 at different heights, providing installation and sliding space for the subsequent flexible abutment plates 45.

[0023] A lead screw 46 is rotatably connected to the inner wall of the through groove along the length of the groove. The lead screw 46 is threaded to the middle of the flexible abutment plate 45. The back of the lead screw 46 extends to the outside of the baffle 42, and a turntable 47 is fixedly connected to the back of the lead screw 46. The turntable 47 is used to drive the lead screw 46 to rotate around its own axis. The flexible abutment plate 45 can slide along the slide groove 411 and can adjust the abutment position according to the size of the meat product, forming a flexible limit on the meat product and avoiding damage to the meat product by rigid limit. The through groove on the same horizontal plane provides space for the installation of the lead screw 46 and the movable block, ensuring that the lead screw 46 can drive the flexible abutment plate 45 to move stably.

[0024] The circulation structure 5 includes a round hole, a fan 51, and a filter 52. The round hole is located on the front of the tray 3, and there are two round holes in total, which are symmetrically distributed. The fan 51 is fixedly installed inside the round hole and is used to drive air to circulate between the tray 3 and the preservation box 1. The filter 52 is fixedly installed in front of the fan 51 and is used to cover the front opening of the round hole. The fan 51 actively drives the airflow, which can accelerate the diffusion of the cold air generated by the ice pack on the tray 3 into the preservation box 1, improve the cold air circulation speed, quickly reduce and maintain the temperature inside the box, and improve the preservation efficiency.

[0025] A fixed base 53 is fixedly installed on the outer wall of the drawer 3. A hydraulic buffer rod is fixedly installed on the inner wall of the fixed base 53. A spring 54 is sleeved on the outside of the hydraulic buffer rod. The axis of the spring 54 coincides with the axis of the hydraulic buffer rod.

[0026] One end of the spring 54 is fixedly connected to a plug rod 55. One end of the plug rod 55 is fixedly connected to the movable end of the hydraulic buffer rod. The inner wall of the insulation cover 6 is provided with a plug hole. The inner diameter of the plug hole is adapted to the outer diameter of the plug rod 55. The plug rod 55 can be inserted into the plug hole. The plug rod 55 is used to limit the relative sliding between the drawer 3 and the insulation cover 6. After the plug rod 55 is inserted into the plug hole, it can lock the relative position of the drawer 3 and the insulation cover 6, preventing the drawer 3 from sliding out on its own due to bumps during transportation, while ensuring that the insulation cover 6 is tightly closed to reduce the leakage of cold air.

[0027] Both sides of the inner wall of the placement drawer 3 are provided with through holes that are connected to the cold air channel 2. The through holes are used to allow cold air to circulate between the placement drawer 3 and the cold air channel 2. When the fan 51 rotates, it can cause the cold air generated by the ice pack on the placement drawer 3 to pass through the through holes, the cold air channel 2 and the ventilation hole 44 in sequence, and be transmitted to the middle area of ​​each set of placement plates 43. The rotation of the fan 51 accelerates the flow of cold air, so that the cold air circulates efficiently along the path of the placement drawer 3, the through holes, the cold air channel 2, the ventilation hole 44 and the area of ​​the placement plate 43, ensuring that the meat on each set of placement plates 43 can be in contact with sufficient cold air and maintain the freshness of the meat.

[0028] Work steps: Open the insulation cover 6, place the ice pack into the placement drawer 3, then place the fresh meat on the placement plate 43, and rotate the turntable 47 on the outside of the baffle 42 to rotate the screw 46 in the through groove. As the screw 46 rotates, it will be connected to the flexible abutment plate 45 by threads, thereby causing the flexible abutment plate 45 to slide along the slide groove 411 of the U-shaped plate until the flexible abutment plate 45 flexibly presses against the meat, completing the limiting and fixing of the meat. Then close the insulation cover 6, and pull the insertion rod to insert it into the insertion hole on the inner wall of the insulation cover 6 under the action of the spring 54 and the hydraulic buffer rod, locking the relative position of the placement drawer 3 and the insulation cover 6. Then start the fan 51 to drive the air flow, causing the cold air generated by the ice pack in the placement drawer 3 to enter the cold air channel 2 through the through holes on both sides of the placement drawer 3, and then through the U-shaped plate. The array of ventilation holes 44 on the baffle plate 42 transmits the air to the meat area of ​​each set of placement plates 43, forming a cold air circulation. During transportation, the cold air channel 2 maintains a uniform temperature inside the box to ensure the freshness of the meat. After arriving at the destination, the meat can be taken out by opening the heat preservation cover 6.
