Advantages and introduction of packaging machine
With the continuous improvement of people's living standards, the demand for various convenience foods has also greatly increased, which has further stimulated the rapid development of my country's food packaging industry. Vacuum packaging machine is one of the fastest growing packaging machinery and has broad prospects for development. There are many types of vacuum packaging machines. Let me introduce you to the vacuum packaging machines.
People often put the packaged objects on the outside of the vacuum chamber to complete the vacuum packaging equipment called vacuum packaging machine.
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.
1. Part of the air (oxygen) in the packaging container is excluded, which can effectively prevent food spoilage.
2. The use of packaging materials with excellent barrier properties (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.
3. 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.
