Summer heat accelerates food spoilage. For ready-to-eat meats, cheese, and prepared meals, standard vacuum packaging removes oxygen but doesn't replace it with a protective atmosphere.
Our automatic vacuum packing machine is a dual chamber vacuum sealer with gas flush packaging capability (nitrogen or nitrogen+CO₂ mix).
How it works:
Bag placed in chamber
Air evacuated (vacuum level adjustable from 50% to 99.9%)
Nitrogen flushing system injects gas mixture
Sealing bar closes (impulse or constant heat)
Real shelf life extension data (tested with cooked chicken breast, 4°C storage):
| Packaging method | Shelf life (days) |
|---|---|
| No vacuum | 4 days |
| Standard vacuum | 7 days |
| Vacuum + N₂ flush | 21 days |
| Vacuum + 70% N₂ / 30% CO₂ | 30 days |
The dual-chamber design alternates cycles, achieving 3-5 cycles/min (depending on gas flush time). This cooked meat packaging solution is also ideal for ready meal vacuum packer applications.
