External vacuum packing machine is to put suction nozzle into the packaging bag, evacuating the air, and then withdraw from the suction nozzle, and then complete the sealing. For external vacuum packaging machine, there are generally 1~4 nozzles. The power source of the sealing line is usually a cylinder or motor. A complete vacuum packaging system includes a vacuum pump, vacuum gauge and vacuum solenoid valve.
Advantages
1. Stainless steel construction make the machine longer lifetime.
2. T-shape silicone sealing strip and anodized aluminium sealing bar.
3. Easy operating system provide 9 memorized program to seal different material or different thickness.
4. Maximum safety protection.
5. Small in size,which save lots of space.
6. This external vacuum packaging machine is used in food field,such as seafood, fruits, tea, salt, soy products and so on, to prevent the oxidation and prolong shelf life.
7. Stainless operating platform just can be adjusted according to the thickness of the packing materials and not be limited to product appearance size, so for large parts or shaped items this machine is most suitable.
8. Only pump air in packaging bag, fast speed(only 2 ~ 3 seconds to complete).
9. The sealing pressure is provided by variable air cylinder of large bore and has strong sealing pressure which completely change the unstable phenomenon of traditional packaging and sealing.
