With the rapid development of the frozen food market, producers face increasingly stringent demands for packaging efficiency, accuracy, and product integrity. Traditional packaging methods often struggle with challenges such as low efficiency, high bag breakage rates, and inaccurate weighing when handling products like frozen dumplings, which are prone to sticking and have irregular shapes. Leveraging 15 years of industry expertise, Hangzhou ZON Packaging Machinery Co., Ltd. (ZONPACK) introduces a fully automated integrated “Weighing-Making-Filling” packaging system specifically designed for frozen dumplings, providing food enterprises with an efficient, stable, and hygienic complete packaging solution.
Addressing Industry Pain Points with Customized Design
Solving Sticking Challenges: The system core features the ZH-A14 multihead weigher, specially equipped with dimple hopper design, significantly reducing the contact area between dumplings and the hopper surface, effectively preventing sticking and ensuring smooth discharge.
Ensuring Clean Production: The weigher adopts a fully waterproof design and 304 stainless steel frame, adapting to the condensate environment common in frozen food production, easy to clean, and meeting stringent food hygiene standards.
Guaranteeing Perfect Seals: The vertical packaging machine (ZH-V620) innovatively incorporates material receiving devices and bag buffer devices, preventing dumplings from falling during the sealing process, drastically reducing bag breakage rates, and ensuring neat, secure packaging.
Fully Automated Production Line for Efficient Operation
This system integrates a complete workflow from elevation, weighing, conveying, and bag making to finished product output. Dual elevators ensure continuous and stable material supply; the high-precision multihead weigher (accuracy ±0.1-1.5g, speed 60 bags/min) accurately controls weight per bag; the high-speed VFFS machine (Siemens PLC control) flexibly produces various bag types. Optional modules such as checkweighers, metal detectors, and rotary sorting tables can be added based on requirements.
Core Value: Enhancing Comprehensive Benefits
Increase Efficiency: Full automation replaces manual labor, significantly boosting daily output.
Reduce Costs: Precise weighing minimizes material waste; lower bag breakage and rework rates save costs; reduces long-term labor expenses.
Ensure Quality: Standardized packaging guarantees product consistency; excellent seal integrity extends product shelf life.
Flexible Adaptation: Quick changeover of bag formers meets production needs for different dumpling specifications.
