Description

Technical Field

[0001] This utility model relates to the field of fresh potato vermicelli preservation, and in particular to a modified atmosphere preservation device for fresh potato vermicelli. Background Technology

[0002] Fresh potato vermicelli, a food that combines good taste and convenience, is favored by the market because it does not require soaking and can be cooked and eaten immediately. However, its high moisture content makes it easy for microorganisms (such as mold and E. coli) to grow, and the starch oxidizes rapidly in an aerobic environment, causing problems such as the vermicelli becoming moldy, sticking together, and deteriorating in taste.

[0003] Among existing preservation technologies, modified atmosphere packaging (MAP) technology creates a micro-modified atmosphere by injecting a specific ratio of nitrogen and carbon dioxide into the packaging, thereby inhibiting microbial growth and oxidation reactions. It is one of the mainstream solutions in the current food preservation field.

[0004] However, in the actual operation of existing semi-automatic modified atmosphere packaging machines, the current equipment still relies on manual loading and unloading operations. That is, fresh wet potato vermicelli must first be packed into packaging boxes one by one, then the filled packaging boxes are placed on the processing table in sequence, and then the processing table is pushed into the packaging machine to start processing. After packaging is completed, the finished packaging boxes must be removed manually, and the above steps are repeated for the next round of filling and pushing. This causes the equipment to stop frequently during the loading and unloading process, which not only causes the continuity of the production line to be interrupted, but also significantly reduces the overall packaging efficiency, making it difficult to meet the high efficiency and stability requirements of industrial production. Therefore, a modified atmosphere packaging device for fresh wet potato vermicelli is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modified atmosphere packaging device for fresh potato vermicelli, which aims to improve the problem in the prior art that "semi-automatic modified atmosphere packaging machines rely on manual loading and unloading operations, which leads to frequent machine stops during filling and unloading, resulting in interruptions in the production line and low overall packaging efficiency".

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a modified atmosphere packaging (MAP) device for fresh wet potato vermicelli, comprising a MAP packaging frame and a packaging film installed on the right side of the MAP packaging frame. A packaging platform is located at the top center of the MAP packaging frame, and a pre-storage component is located at the top of the packaging platform. The pre-storage component includes a movable platform, with dovetail blocks fixedly connected to both the front and rear surfaces of the movable platform. Storage racks are fixedly connected to the left and right sides of the MAP packaging frame near the packaging platform. The two sets of storage racks and the packaging platform are positioned at the front and rear... The inner walls are all provided with dovetail grooves, and the dovetail blocks are slidably connected to the inner walls of multiple sets of dovetail grooves. The moving platform is slidably connected to the inner walls of the packaging platform and the two sets of storage racks. Positioning triangles are fixedly connected to the top center of the packaging platform and the top center of the moving platform near each other. The middle of the packaging platform is provided with a through groove for the moving platform to move. The middle of the packaging platform is fixedly connected to the bottom end by a connecting rod. The outer sides of the two sets of storage racks are fixedly connected with baffle one. The top of the middle part of the modified atmosphere packaging machine frame is fixedly connected with baffle two on the front surface of the packaging platform.

[0007] As a further description of the above technical solution:

[0008] The pre-storage component also includes two sets of spheres. The two sets of spheres are slidably connected to the front and rear inner walls of the through groove in the middle of the packaging platform. The two sets of spheres are elastically connected to the packaging platform by a reset spring. The front and rear surfaces of the two sets of dovetail blocks are provided with circular grooves in the middle. The two sets of spheres are respectively engaged with the inner walls of the two sets of circular grooves.

[0009] As a further description of the above technical solution:

[0010] The storage rack is L-shaped and hollow in the middle.

[0011] As a further description of the above technical solution:

[0012] The second baffle is U-shaped with its opening facing downwards.

[0013] As a further description of the above technical solution:

[0014] An adjustment component is provided on the upper right side of the modified atmosphere packaging machine frame. The adjustment component includes two sets of support frames, both of which are fixedly connected to the upper right side of the modified atmosphere packaging machine frame.

[0015] As a further description of the above technical solution:

[0016] Both sets of support frames have a sliding groove in the middle, and the inner walls of both sets of sliding grooves are slidably connected to sliders. A compression tube is rotatably connected between the two sets of sliders.

[0017] As a further description of the above technical solution:

[0018] A threaded rod is fixedly connected to the front surface of the slider located in front, and a threaded sleeve is threadedly connected to the outer wall of the threaded rod.

[0019] As a further description of the above technical solution:

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a modified atmosphere packaging (MAP) device for fresh potato vermicelli, comprising a MAP packaging frame 1 and a packaging film 7 installed on the right side of the MAP packaging frame 1. The MAP packaging frame 1 is equipped with a vacuum system to remove air from the packaging box, and then filled with a proportionally mixed preservative gas such as nitrogen and carbon dioxide to form a modified atmosphere environment. The packaging film 7 has excellent gas barrier properties, effectively preventing oxygen and water vapor from entering the packaging, while also possessing good flexibility and heat-sealing properties. The top of the unit is equipped with a packaging platform 3 for raising support and movement. The top of the packaging platform 3 is equipped with a pre-storage component 2, which includes a moving platform 21. After placing the potato fresh vermicelli packaging box on the two holes on the moving platform 21, the packaging platform 3 can be pushed into the modified atmosphere packaging machine frame 1 for processing and packaging. The front and rear surfaces of the moving platform 21 are fixedly connected with dovetail blocks 29 that cooperate with dovetail grooves 24 to make the moving platform 21 move stably. The middle part of the modified atmosphere packaging machine frame 1, near the left and right sides of the packaging platform 3, is fixedly connected with storage racks 22 to support the moving platform 21.

[0032] Furthermore, dovetail grooves 24 are provided on the front and rear inner walls of both sets of storage racks 22 and packaging platform 3. Dovetail blocks 29 are slidably connected to the inner walls of multiple sets of dovetail grooves 24. The dovetail grooves 24 and dovetail blocks 29 are all rectangular in shape, which can increase the tightness and stability of movement. The moving platform 21 is slidably connected to the inner walls of packaging platform 3 and two sets of storage racks 22. Positioning triangles 6 are fixedly connected at the top center of packaging platform 3 and the top center of moving platform 21, which are close to each other. The setting of two sets of positioning triangles 6 can easily position the moving platform 21 in the center position. A through groove is provided in the middle of packaging platform 3 to allow the moving platform 21 to move. The middle part of the frame 3 is fixedly connected to the bottom by a connecting rod 5. Both sets of storage racks 22 are fixedly connected to the outside of the moving platform 21 to prevent it from falling off. The top of the middle part of the modified atmosphere packaging machine frame 1 is fixedly connected to the front surface of the packaging platform 3 by a baffle 25. The baffle 25 positions and limits the packaging platform 3, and at the same time makes the multiple sets of dovetail grooves 24 in front and rear aligned. At this time, the packaging boxes and moving platform 21 processed on the packaging platform 3 can be easily moved to the left, and then the other set of moving platform 21 on the right side can be moved to the middle of the packaging platform 3. At this time, packaging processing can be carried out quickly, reducing downtime and downtime for loading and unloading.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The pre-storage component 2 also includes two sets of spheres 27, which are slidably connected to the front and rear inner walls of the through groove in the middle of the packaging table 3. Both sets of spheres 27 are elastically connected to the packaging table 3 by return springs 26. Circular grooves 28 are opened in the middle of the front and rear surfaces of the two sets of dovetail blocks 29, and the two sets of spheres 27 are respectively engaged with the inner walls of the two sets of circular grooves 28. The storage rack 22 is L-shaped and hollow in the middle. The L-shape allows it to be fixed on the modified atmosphere packaging machine frame 1 and provides support. The baffle 25 is U-shaped with its opening facing downwards and can be fixed on the modified atmosphere packaging machine frame 1. The modified atmosphere packaging machine frame 1 can simultaneously block the packaging table 3. When the moving stage 21 is moved towards the center of the packaging table 3, the moving stage 21 and the dovetail block 29 can squeeze the ball 27 and the return spring 26. When it moves to the circular groove 28 and aligns with the ball 27, the elastic force of the return spring 26 causes the ball 27 to quickly return and lock into the circular groove 28, thus positioning the moving stage 21. This ensures that the moving stage 21 is in the center of the packaging table 3, and the packaging table 3 can be moved into the modified atmosphere packaging machine frame 1 for processing, ensuring the processing quality.

[0034] Reference Figure 1 Figure 4An adjustment component 4 is provided on the upper right side of the modified atmosphere packaging machine frame 1. The adjustment component 4 includes two sets of support frames 41 that provide support. Both sets of support frames 41 are fixedly connected to the upper right side of the modified atmosphere packaging machine frame 1. The middle of each set of support frames 41 is provided with a groove 42 that provides stable movement of the slider 43. The inner wall of each set of grooves 42 is slidably connected to the slider 43 that supports the extrusion tube 46. The extrusion tube 46 that can press the packaging film 7 and tighten it is rotatably connected between the two sets of sliders 43. The front surface of the front slider 43 is fixedly connected to a threaded rod 45 that can position the extrusion tube 46 by cooperating with a threaded sleeve 44. The outer wall of the threaded rod 45 is threadedly connected to the threaded sleeve 44. The rear surface of the threaded sleeve 44 is fixedly connected to a rubber ring. The rubber ring is pressed and contacts the front surface of the front support frame 41. The rubber ring is made of rubber. When the threaded sleeve 44 is rotated, it is threadedly connected to the threaded rod 45, causing the threaded sleeve 44 to move inward and drive the rubber ring to move inward and press it on the support frame 41, thereby positioning the extrusion tube 46.

[0035] Working principle: When in use, fresh wet potato vermicelli is packed into a packaging box, which is then placed in the two mounting holes at the top of the moving platform 21. By observing the positioning triangle 6 at the top of the packaging platform 3 and the moving platform 21, the moving platform 21 is manually pushed so that the dovetail block 29 slides along the dovetail groove 24 on the inner wall of the storage rack 22 and the packaging platform 3. When the moving platform 21 moves towards the center of the packaging platform 3, the dovetail block 29 squeezes the ball 27 and the return spring 26. When the groove 28 on the dovetail block 29 is aligned with the ball 27, the return spring 26 pushes the ball 27 into the groove 28, completing the center positioning of the moving platform 21 on the packaging platform 3, ensuring the accuracy of subsequent packaging.

[0036] After the packaging box is positioned, the packaging table 3 is pushed to move the mobile table 21 to the designated packaging station. The modified atmosphere packaging machine frame 1 is started, and the packaging film 7 covers the packaging box under the traction of the equipment. The equipment removes the air inside the packaging box through the vacuum system and then fills it with a proportionally mixed preservation gas such as nitrogen and carbon dioxide to form a modified atmosphere environment. Subsequently, the heat sealing device heats and pressurizes the packaging film 7 and uses the good heat sealing performance of the packaging film 7 to achieve a seal, thus completing the packaging of the fresh potato vermicelli. At the same time, during the packaging process, the packaging box containing the fresh potato vermicelli can be placed in advance on the mobile table 21 on the right storage rack 22 for preparation.

[0037] After the packaging boxes on the packaging table 3 are packaged and sealed, the packaging table 3 is pulled outward to move the packaged products out of the packaging station along with the moving table 21. The packaging table 3 is positioned and limited by the baffle 25, so that the front and rear dovetail grooves 24 on the packaging table 3 are aligned with the front and rear dovetail grooves 24 on the two sets of storage racks 22. The moving table 21 and the packaged products are pushed to the left onto the left storage rack 22. Then, the moving table 21 on the right storage rack 22, which has been pre-placed with new vermicelli packaging boxes, slides along the dovetail groove 24 into the middle of the packaging table 3. The packaging table 3 can then be directly pushed into the modified atmosphere packaging machine frame 1, thereby quickly entering the next round of packaging process, reducing downtime for loading and unloading, and improving packaging efficiency.

[0038] The adjustment component 4 on the upper right side of the modified atmosphere packaging machine frame 1 is responsible for pressing the packaging film 7. By rotating the threaded sleeve 44, it moves inward in a threaded engagement with the threaded rod 45, causing the rubber ring to press against the front support frame 41, thereby fixing the position of the slider 43 and determining the position of the extrusion tube 46. The extrusion tube 46 can press and tighten the packaging film 7 to ensure that the packaging film 7 is flat and wrinkle-free, providing good conditions for subsequent sealing.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
