The benefits of the use of food vacuum packaging machine

Vacuum, the term is translated from Latin vacuo, the significance of nothingness. In fact, the vacuum should be understood thin space as a gas. In the designated space, less than an atmospheric pressure gas state are collectively referred to as a vacuum. ( granule packing machine http://www.shpackingmachine.com) thin extent of the gas in the vacuum state called the vacuum (degree ofvacuum), usually the pressure value. Vacuum packaging is not actually the degree of vacuum within the vacuum, vacuum packaging technology, packaging, food containers usually in the 600-1333Pa. So, in turn vacuum packaging known as decompression packaging or exhaust packaging.

???? Food vacuum packing food packaged is, out of the packaging bag of air to achieve the desired degree of vacuum, to complete the sealing process. Very common in the food industry, vacuum packaging applications, a variety of cooked products such as chicken, ham, sausage, grilled fish, beef jerky, etc.; pickled products such as a variety of pickled vegetables and soy products, preserved fruit, a variety of needs of fresh food more more use of vacuum packaging. After a long shelf life of vacuum-packed food, greatly extend the shelf life of food.

Use of technology

Vacuum packaging of food into the bags out of the packaging bag of air to achieve the desired vacuum, and then charge into nitrogen or other gas mixture, and then complete the sealing process.

Vacuum packaging technology originated in the 1940s. 1950, polyester, polyethylene plastic film used for vacuum packing, after vacuum packaging will be the rapid development of

China's vacuum packaging technology is developed in the early 1980s, vacuum inflatable packaging technology in the early 1990s began a small amount of use, its scope is more extensive with the small package promotion and development of supermarket, , some of which will gradually replace the rigid packaging, a good prospect.

Food vacuum packaging benefits:

Excluded part of the packaging container of air (oxygen), can effectively prevent food spoilage;

(Tightness) and excellent packaging materials and strict barrier sealing technology and requirements, can effectively prevent the exchange of the packaging and contents of substances, to avoid food weight loss, loss of taste, but will also prevent the secondary pollution;

When the internal gas of the vacuum-packed containers has been ruled out, to accelerate the heat conduction, which can improve the efficiency of heat sterilization, but also to avoid the pasteurization, due to the expansion of the gas leaving the containers burst;
