Description: vacuum packaging machine is a semi-automatic vacuum equipment, the use of a vacuum chamber cover pressing machine automatically according to set procedures to complete vacuum, sealing, printing, exhaust the entire process. Vacuum-packaged products to prevent oxidation, mold, insects, variable tide, can be kept fresh and prolong the storage period. Food deprived of the use of vacuum packaging machine vacuum after which an advantage to exclude part of the packaging container of air (oxygen), can effectively prevent food spoilage. 2, the use of barrier (tightness) excellent packaging materials and sealing technology and strict requirements, can effectively prevent the exchange of substances in the package contents can be avoided by food weight loss, loss of taste, but also to prevent secondary pollution. 3, vacuum-packed container internal gas has been ruled out, accelerated heat conduction, which can improve the efficiency of heat sterilization, but also to avoid the heat sterilization, due to expansion of the gas leaving the container rupture. In the food industry, vacuum packaging applications is very common, a variety of cooked products such as chicken, ham, sausage, grilled fish, beef jerky, etc.; various pickles and pickled products such as soy products, dried fruit and other kinds of fresh food needs increasing use of vacuum packaging. After vacuum-packed food preservation and long, greatly extend the shelf life of food.
