With the continuous improvement of people's living standards, the demand for various convenience foods has also increased greatly, which has further stimulated the rapid development of China's food packaging industry. Vacuum packaging machine is one of the faster development of packaging machinery, has broad prospects for development. There are many kinds of vacuum packaging machines. Here is a brief introduction to the vacuum packaging machine.

Definition

People often put the packaged goods on the outside of the vacuum chamber to complete the vacuum packaging equipment called vacuum packaging machine.

Features

Part of the air (oxygen) in the packaging container is excluded, which can effectively prevent food spoilage.

2, the use of barrier (air tightness) excellent packaging materials and strict sealing technology and requirements, can effectively prevent the exchange of packaging materials, 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 can improve the efficiency of thermal sterilization, and also avoids the expansion of the gas during heating and sterilization.

In the food industry, the application of vacuum packaging is very common, a variety of cooked products such as chicken legs, ham, sausages, etc.; pickled products such as various pickles and bean products, preserved fruits and other kinds of food that need to be preserved are increasingly using vacuum packaging.
