The principle of Vacuum packaging machine is through the exhaust nozzle into the packaging bag, evacuated air, exit the exhaust nozzle, and then complete the sealing.
The characteristics of
1. eliminate part of the air (oxygen) in the packaging container, can effectively prevent food spoilage.
2. the use of barrier (air tightness) good packaging materials and strict sealing technology and requirements, can effectively prevent the exchange of packaging content material, can avoid food weight loss, tasteless, and can prevent secondary pollution.
3. The internal gas of the vacuum packaging container has been eliminated, which accelerates the conduction of heat, which can improve the efficiency of hot sterilization, and avoid the rupture of the packaging container due to the expansion of gas when heating sterilization.
In the food industry, vacuum packaging application is very common, all kinds of cooked products such as chicken legs, ham, sausage, etc. Vacuum packaging is increasingly used in pickled products such as pickles, soy products, preserved fruits and other foods that need to keep fresh. Vacuum-packed food has a long shelf life, greatly extending the shelf life of food.
