With the continuous improvement of people's living standards, the demand for a variety of convenience foods has also increased, which has further stimulated the rapid development of China's food packaging industry. Vacuum packaging machine is one of the fastest growing packaging machines and has a broad prospect of development. There are many types of vacuum packaging machines. Here's a look at the vacuum packaging machine.
People often put the packaged goods on the outside of the vacuum chamber to complete vacuum packaging equipment called vacuum packaging machine.
The 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.
1. Excluding part of the air (oxygen) in the packaging container can effectively prevent food spoilage.
2, the use of barrier (airtight) excellent packaging materials and strict sealing techniques and requirements can effectively prevent the exchange of the contents of the package, you can avoid food weight loss, loss of taste, but also to prevent secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, which accelerates the conduction of heat, which improves the heat sterilization efficiency, and also avoids the rupture of the packaging container due to the expansion of the gas during heat sterilization.
In the food industry, vacuum packaging applications are very common, a variety of cooked products such as chicken legs, ham, sausages, etc.; pickled products such as various pickles and soy products, preserved fruits and other foods need to be used in more and more vacuum package. Vacuum-packaged foods have a long shelf life, greatly extending the shelf life of foods.
