The three major definitions of vacuum packaging machine

The vacuum packaging machine can automatically withdraw the air inside the packaging bag and complete the sealing process after reaching a predetermined vacuum level. It can also be recharged with nitrogen or other gas mixture and then complete the sealing process. Vacuum packaging machines are often used in the food industry because, after being vacuum-packed, foods can be anti-oxidized to achieve long-term preservation.

First, the definition of external pump vacuum packaging machine:

People often put the packaged goods on the outside of the vacuum chamber to complete the vacuum packaging equipment called external vacuum packaging machine. Outlet vacuum packaging machines are designed primarily for vacuum packaging of larger packages.

Second, the principle of external vacuum packaging machine:

Different from the structure of the internal vacuum packaging machine, the external vacuum packaging machine is placed in the packaging bag of the packaged object by means of a suction nozzle, evacuating the air, exiting the suction nozzle, and then completing the sealing. Outlet vacuum packaging machines generally have 1~4 suction nozzles. The power source of the sealing line is generally a cylinder or a motor.

Third, the classification of external pump vacuum packaging machine:

The external pumping vacuum packaging machine is divided into a horizontal vacuum pumping machine and a vertical vacuum pumping machine according to the location of the packaging. The horizontal packed vacuum packaging machine is horizontally placed; the vertical external vacuum packaging machine is vertically placed. Horizontal vacuum packers are more common in the market.
