1, excluding some of the air (oxygen) in the packaging container, can effectively prevent food spoilage.
Vacuum packaging machine 2, the use of barrier (airtight) excellent packaging materials and strict sealing technology and requirements, can effectively prevent the exchange of packaging content material, which can avoid food weight loss, loss of flavor, but also to prevent secondary pollution.
3, vacuum packaging containers have been excluded from the internal gas, accelerating the conduction of heat, which can improve the efficiency of heat sterilization, but also to avoid the heating sterilization, due to the expansion of the gas and make the container rupture.
Vacuum packaging machine is a plastic or plastic aluminum foil film as a packaging material, liquid, solid, powdery paste food, food, fruit, pickles, dried fruit, chemicals, herbs, electronic components, precision instruments, rare metals, etc., vacuum-packed items can be prevented from oxidation, mildew, insect damage, rot, moisture, to prolong the preservation of freshness period. Particularly suitable for tea, food, medicine, stores, research institutions and other industries, has a beautiful appearance, compact structure, high efficiency, easy to operate and other advantages
In the food industry, vacuum packaging applications are very common, a variety of cooked products such as chicken legs, ham, sausage, grilled fish fillets, beef jerky, etc.; pickled products such as a variety of sauces, as well as soybean products, preserved fruits and other kinds of food need to preserve freshness is increasingly more The use of vacuum packaging. After the vacuum packaging of food preservation period is long, greatly extending the shelf life of food.
The main mechanism: the main role of vacuum packaging is to remove oxygen, in order to help prevent food spoilage, the principle is relatively simple, because the food mold deterioration is mainly caused by microbial activity, and most of the microorganisms (such as molds and yeasts) survival is the need for oxygen, and the vacuum packaging is the use of this principle, the bag and the food cells within the oxygen pumped off, so that microorganisms lose the survival of the The vacuum packaging is the application of this principle.
Application: suitable for all kinds of food, meat products, seafood, fruits and vegetables, sauces, cooling meat, pharmaceutical products, hardware components, medical equipment, etc. for vacuum, inflatable, close to the body of the packaging machine
