With the continuous improvement of people's living standards, the demand for a variety of convenient food also increased, which nearly a step to stimulate the rapid development of China's food packaging industry. Vacuum packaging Machine is one of the rapid development of packaging machinery, has a broad development prospects.
Vacuum packaging machine types are divided into many kinds, the following to introduce a vacuum packaging machine.
People often put the packaging to the outer side of the vacuum chamber to complete the vacuum packaging equipment called vacuum packaging machine.
Principle of packing machine
Vacuum packaging machine is through the suction nozzle into the packaging bag, take out the air, exit the exhaust nozzle, and then complete the seal.
Characteristics of packing machine
1, the exclusion of the packaging container part of the air (oxygen), can effectively prevent food spoilage.
2, the use of barrier (gas tightness) excellent packaging materials and strict sealing technology and requirements, can effectively prevent the exchange of packaging content material, you can avoid food weight loss, taste, and prevent two times pollution.
3, the vacuum packaging container inside the gas has been eliminated, accelerating the heat conduction, which can improve the heat sterilization efficiency, but also to avoid heating sterilization, due to the expansion of the gas and the packaging container rupture. In the food industry, vacuum packaging applications are very common, all kinds of cooked products such as chicken legs, ham, sausages, etc. pickled products such as a variety of pickles and soy, preserved fruit and other food needs more and more use of vacuum packaging.
After the vacuum packaging of food preservation period long, greatly extend the shelf life of food.
