Description

Technical Field

[0001] This utility model relates to the field of duck accessory packaging technology, and in particular to a vacuum nitrogen-filled packaging device for duck accessories. Background Technology

[0002] Duck offal, mainly including duck neck, duck feet, duck wings, and duck gizzard, is made through processes such as cleaning, marinating, braising, or air-drying. It has a rich flavor and is commonly found in snacks or catering ingredients. Its vacuum nitrogen-filled packaging removes air and then injects high-purity nitrogen, effectively inhibiting microbial growth and oil oxidation. This technology, combined with the high barrier properties of aluminum foil or nylon bags, can extend the shelf life of duck offal at room temperature while maintaining its flavorful taste and color. The injected nitrogen can also buffer pressure, prevent fragile parts from breaking, and improve product integrity. This packaging method is widely used in ready-to-eat duck products, balancing convenience and quality stability, and meeting consumers' needs for safety and long-lasting freshness.

[0003] In the current field of vacuum nitrogen-filled packaging for foods such as duck parts, traditional equipment generally adopts a structural design with independently set "oxygen extraction port" and "nitrogen filling port" to achieve the separation of oxygen extraction and nitrogen filling functions. In the actual production process, when switching to the nitrogen filling process after completing the oxygen extraction process, due to the spatial separation of the two interfaces, traditional equipment needs to use a servo motor to drive the packaging cavity to move laterally along a horizontal slide rail, or control the overall lifting and lowering of the top pressure head to adjust the docking height of the nitrogen filling port connector, so that the nitrogen filling port sealing connector is accurately embedded into the pre-set interface groove of the cavity. During this movement, on the one hand, the cavity and the fixed Temporary misalignment of the sealing surfaces can easily occur due to gaps in the guide rail assembly and vibrations during mechanism operation. External air can quickly seep into the cavity through the misalignment gaps, disrupting the low-oxygen environment created by the initial oxygen extraction and leading to an increase in residual oxygen levels inside the packaging. On the other hand, the oxygen extraction port connector may detach from the original sealing groove when the cavity moves. The rubber sealing ring may undergo temporary deformation or partial detachment from the sealing groove due to uneven stress. This can not only cause nitrogen to leak from the oxygen extraction port interface during subsequent nitrogen filling, but also accelerate wear due to repeated friction and compression of the sealing ring, shortening its replacement cycle and increasing the difficulty of equipment maintenance and downtime.

[0004] Therefore, it is necessary to invent a vacuum nitrogen-filled packaging device for duck accessories to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vacuum nitrogen-filling packaging device for duck accessories, to solve the problem mentioned in the background art. In the actual production process, when switching from the oxygen extraction process to the nitrogen filling process, due to the separation of the two interfaces, traditional equipment needs to use a servo motor to drive the packaging cavity to move laterally along the horizontal slide rail, or control the overall lifting and lowering of the top pressure head to adjust the docking height of the nitrogen filling port connector, so that the nitrogen filling port sealing connector is accurately embedded into the pre-set interface groove of the cavity. During this movement, on the one hand, the cavity and the fixed sealing surface are prone to temporary sealing misalignment due to the gap in the guide rail assembly and the vibration of the mechanism. External air will quickly seep into the cavity from the misalignment gap, destroying the low-oxygen environment formed by the previous oxygen extraction, resulting in an increase in the residual oxygen in the packaging. On the other hand, the oxygen extraction port connector will detach from the original sealing groove when the cavity moves. The rubber sealing ring will undergo temporary deformation or partial detachment from the sealing groove due to uneven force. This will not only cause nitrogen to leak from the oxygen extraction port interface during the subsequent nitrogen filling process, but also accelerate the wear of the sealing ring due to repeated friction and compression, shorten its replacement cycle, and increase the difficulty of equipment maintenance and downtime.
