What is a packaging machine?
With the continuous improvement of people's living standards, the demand for various convenience foods has also increased greatly, which has promoted the rapid development of China's food packaging industry. Vacuum packaging machine is one of the packaging machinery with rapid development, and has broad prospects for development. There are many kinds of vacuum packaging machines. Here we introduce the vacuum packaging machine.
People often put the package outside the vacuum chamber to complete the vacuum packaging equipment called vacuum packaging machine.
Vacuum packaging machine is through the suction nozzle placed in the packaging bag of the package, air extraction, exit the suction nozzle, and then complete sealing.
1. Eliminating part of the air (oxygen) in the packaging container can effectively prevent food spoilage.
2. The use of good barrier (air tightness) packaging materials and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, which can avoid food weight loss, odor loss and secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, which accelerates the heat transfer. This can improve the efficiency of heat sterilization and avoid the cracking of the packaging container due to the expansion of the gas when heating sterilization.
In the food industry, vacuum packaging is widely used. Various kinds of cooked products such as chicken leg, ham, sausage, etc. and pickled products such as pickles, soybean products, preserved fruits and other foods that need to be preserved are increasingly used in vacuum packaging. Vacuum packaged food has a long shelf life, which greatly prolongs the shelf life of food.
