The vacuum packaging machine can automatically withdraw the air inside the packaging bag and complete the sealing process after reaching a predetermined vacuum level. It can also be recharged with nitrogen or other gas mixture and then complete the sealing process. Vacuum packaging machine is often used in the food industry, because after vacuum packaging, food can be anti-oxidation, so as to achieve the purpose of long-term preservation, vacuum packaging machine has the following characteristics
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, grilled fish fillets, beef jerky, etc.; pickled products such as various pickles and soy products, preserved fruit and other foods need to be preserved More and more vacuum packaging is used. Vacuum-packaged foods have a long shelf life, greatly extending the shelf life of foods.
