Rotary Vane Vacuum Pump Applied In Vacuum Package Industry

For packaging technology, How vacuum technology to be applied?
Usually, vacuum plays a key role in packaging processes and packaging production. Vacuum technology enables efficient and accurate packaging, thermoforming and coating. In addition, vacuum technology can be used to move, transport, unpack and seal. During the packaging process, the items to be packaged can also be fed and embedded by vacuum.

The process of vacuum packaging and fresh-keeping is to put the food into a special plastic bag, use the rotary vane vacuum pump to suction away the gas in the bag, and then heat the packaged air outlet. After the gas in the bag is suctioned away, vacuum environment is created in the bag, which is characterized by low oxygen partial pressure and low water vapor content; it is beneficial for the gas or other volatile gas inside the food to diffuse into the space. The rotary vane vacuum pump for packaging and fresh-keeping process using these three characteristics to preserve food. Fresh food uses MAP (gas-conditioning packaging technology) to maintain the appearance, freshness and taste of the food.
