Tray-style modified-atmosphere packaging machine (MAP). Vacuums then back-fills the tray with nitrogen or other inert gas mixture before heat-sealing the lid film. Designed for products that cannot tolerate hard vacuum —
Fonctionnement
Pre-formed plastic trays loaded with product enter the sealing chamber. The vacuum pump (Zhongde 40#) evacuates the chamber; the controlled gas mix (typically N₂ or mixed inert gas) is then back-filled to above-atmospheric pressure. The sealing station heat-seals the lid film over the tray, locking in the modified atmosphere. Siemens PLC sequences the full cycle via integrated control circuitry drawing on advanced international technology.
