Preserving Tradition, Engineering the Future — LONGYING Equipment.
Longying’s production line employs specialized sealing equipment tailored to the characteristics of different traditional foods, ensuring quality and safety:
Designed specifically for tray/plastic box packaging with precise positioning.
Utilizes heat sealing or hot-cut cold sealing technology to achieve high-strength sealing between the lid film and the base box.
Key Points: Smooth, aesthetically pleasing finish; oxygen and moisture barrier; locks in filling flavor; extends shelf life.
Core technology lies in the vacuum sealing process.
Removes air from the packaging bag and immediately performs heat melt sealing.
Key Points: Inhibits bacterial growth; maintains the zongzi’s firm and springy texture; significantly extends the shelf life of fresh zongzi.
Often an integrated filling and sealing machine.
Precisely fills viscous jingao into bowls/cups, followed by high-speed automatic film covering and heat sealing.
Key Points: Leak-proof, hermetic seal; flat seal facilitates subsequent steam sterilization; ensures soft, glutinous texture.
Typically employs pillow packaging or vertical bag packaging.
Uses continuous heat-press sealing to rapidly complete back sealing and end sealing.
Key Points: High-efficiency continuous operation; strong seal prevents breakage; light-blocking and moisture-proof protection for the flaky pastry and filling.
