Technical Field
[0001] This utility model belongs to the field of vacuum sealing, specifically relating to a vacuum sealing device for clean potatoes with sterilization function. Background Technology
[0002] With increasing consumer demand for convenient foods, pre-cut potatoes, as a ready-to-eat processed agricultural product that requires no washing or cutting, are gaining popularity due to their fresh taste and high nutritional value. To extend shelf life and maintain quality, vacuum packaging technology has become the mainstream choice for packaging pre-cut potatoes because it effectively isolates oxygen and inhibits microbial growth. Chamber vacuum packaging machines, with their simple operation and strong sealing properties, are widely used in small and medium-sized food processing enterprises.
[0003] However, when processing potatoes containing juice in existing chamber vacuum packaging machines, the negative pressure generated during the vacuuming process easily causes the potato juice to overflow.

[0026] 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.
[0027] This specific embodiment is a vacuum sealing device for pre-cleaned potatoes with sterilization function, and its structural diagram is shown below. Figures 1 to 3 As shown, the machine includes a vacuum packaging machine body 1, a vacuum chamber shell 2 at the upper end of the vacuum packaging machine body 1, a vacuum chamber top cover 3 connected to the upper end of the vacuum chamber shell 2, an ultraviolet sterilization lamp 6 installed at the inner rear end of the vacuum chamber shell 2, a packaging mechanism above the vacuum packaging machine body 1, and the packaging mechanism includes an electric heating rod 401 installed at the rear end of the vacuum packaging machine body 1. Connectors 402 are fixedly connected to the left and right ends of the inner side of the vacuum chamber shell 2, a round shaft 403 is fixedly connected to the inner side of the connector 402, a pressure rod 404 is connected to the outer end of the round shaft 403, and a rotating hole with a through hole is opened at both ends of the pressure rod 404. The outer side of the round shaft 403 is rotatably connected to the inner side of the rotating hole, and the outer sides of both ends of the pressure rod 404 are slidably connected to the inner side of the connector 402. A pad 405 is connected inside the vacuum chamber shell 2. The upper side of the electric heating rod 401 abuts against the lower side of the opening of the potato and vegetable sealed bag, and the lower outer end of the pressure rod 404 abuts against the upper side of the opening of the potato and vegetable sealed bag. The ultraviolet sterilization lamp 6 and the electric heating rod 401 are both connected to the circuit inside the vacuum packaging machine body 1. Thus, after placing the sealed bag containing potatoes and vegetables on the pad 405 with the bag opening above the electric heating rod 401, rotating the pressure rod 404 to the upper side of the bag opening on the pad 405 can press the opening of the potato and vegetable sealed bag tightly onto the pad 405.
[0028] The vacuum chamber shell 2 has a sliding groove at the bottom of the left and right ends of the inner side. The outer sides of the left and right ends of the pad 405 are slidably connected to the inner side of the sliding groove. The rear side of the pad 405 abuts against the rear end of the inner side of the vacuum chamber shell 2. The lower side of the pad 405 is slidably connected to the bottom end of the inner side of the vacuum chamber shell 2. The upper rear end of the vacuum chamber shell 2 is hinged to the rear end of the vacuum chamber top cover 3. The upper side of the vacuum chamber shell 2 abuts against the lower edge of the vacuum chamber top cover 3. The front side of the pad 405 abuts against the front end of the inner side of the vacuum chamber top cover 3. After sliding both ends of the pad 405 into the grooves inside the vacuum chamber shell 2, the vacuum chamber top cover 3 is rotated to the upper side of the vacuum chamber shell 2, with the front end of the vacuum chamber top cover 3 positioned in front of the pad 405. This allows the pad 405 to be fixed inside the vacuum chamber shell 2. When vacuum sealing the potato vegetable bag on the pad 405, the juice overflowing from the potato vegetables will drip into the pad 405. When the potato juice on the pad 405 needs to be cleaned, the vacuum chamber top cover 3 is opened to remove the pad 405 from the vacuum chamber shell 2. A new, clean pad 405 is then installed. While the removed pad 405 is being cleaned, the vacuum packaging of potatoes can continue inside the vacuum chamber shell 2, preventing the cleaning of potato juice from affecting packaging efficiency.
[0029] In addition, a rubber pad is affixed to the lower edge of the vacuum chamber top cover 3. Thus, when the vacuum chamber top cover 3 is rotated to the upper side of the vacuum chamber outer shell 2, the rubber pad on the lower side of the vacuum chamber top cover 3 contacts the upper side of the vacuum chamber outer shell 2, ensuring a seal between the vacuum chamber outer shell 2 and the vacuum chamber top cover 3.
[0030] Cooperate Figure 4As shown, a support unit is provided on the upper side of the pad 405. The support unit includes a T-shaped rod 501 fixedly connected to the upper side of the pad 405. A baffle 502 is connected to the outer end of the T-shaped rod 501. A T-shaped groove is opened at the middle position of the lower end of the baffle 502. The outer side of the T-shaped rod 501 is slidably connected to the inner side of the T-shaped groove. A threaded rod 503 is connected to the middle position of the lower end of the baffle 502. A rotating handle 504 is welded to the upper end of the threaded rod 503. A through groove is opened in the baffle 502 above the T-shaped groove. A through threaded hole is opened in the middle position between the T-shaped groove and the through groove. The outer side of the threaded rod 503 is threadedly connected to the inner side of the threaded hole. The lower end of the threaded rod 503 abuts against the upper side of the T-shaped rod 501. The outer side of the baffle 502 abuts against the bottom of the potato vegetable sealing bag placed on the pad 405. Therefore, after the potato and vegetable sealed bag is placed on the pad 405, the baffle 502 is adjusted and fixed at the bottom of the bag on the outside. This supports the bottom of the potato and vegetable sealed bag and prevents the sealed bag containing potatoes and vegetables from sliding on the pad 405 during the sealing process, which would cause the bag opening to slide off the pad 405 and affect the sealing of the bag.
[0031] Working principle: When vacuum packaging potatoes, first place the sealed bag of potatoes to be sealed on the pad 405 inside the vacuum chamber shell 2, with the bag opening positioned above the electric heating rod 401. Then, rotate the pressure rod 404 to the upper side of the electric heating rod 401. Next, slide the baffle 502 along the outer side of the T-shaped rod 501, moving the baffle 502 to the bottom of the sealed bag. Then, rotate the handle 504 so that the threaded rod 503 rotates in the threaded hole and moves downwards until it abuts against the lower side of the T-shaped rod 501, thus securing the baffle 502. Simultaneously, support the sealed potato vegetable bag, then close the vacuum chamber top cover 3, turn on the ultraviolet sterilization lamp 6 to sterilize the potato vegetables in the vacuum chamber shell 2, then turn on the vacuum packaging machine body 1 to create a vacuum in the vacuum chamber shell 2, then turn on the electric heating rod 401 to generate high temperature to melt the opening of the sealed potato vegetable bag. After the opening is melted and bonded, stop heating the electric heating rod 401. After the molten plastic cools and solidifies to form a strong sealing line, close the vacuum packaging machine body 1, open the vacuum chamber top cover 3, and take out the sealed potato vegetable packaging bag on the pad 405.
[0032] All technical features in this embodiment can be freely combined according to actual needs.
[0033] 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.
