Let me introduce you to the vacuum packaging machines.
definition
People often put the packaged objects on the outside of the vacuum chamber to complete the vacuum packaging equipment called vacuum packaging machine.
principle
The vacuum packaging machine is put into the packaging bag of the packaged object through the suction nozzle, evacuates the air, exits the suction nozzle, and then completes the sealing.
Features

- The use of packaging materials with excellent barrier (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of the contents of the packaging, which can avoid food weight loss, loss of taste, and prevent secondary pollution.
- The gas inside the vacuum packaging container has been removed, which accelerates the conduction of heat, which can improve the efficiency of thermal sterilization and avoid the rupture of the packaging container due to the expansion of the gas during thermal sterilization.
In the food industry, vacuum packaging applications are very common. Various cooked products such as chicken legs, ham, sausages, etc.; pickled products such as various pickles, as well as soy products, preserved fruits and other foods that need to be kept fresh are increasingly using vacuum. Package. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of the food.
