[Wuhan Lugong machinery official website] what is the charge of modified atmosphere packaging machine? Generally speaking, the modified atmosphere packaging machine is filled with nitrogen, oxygen and carbon dioxide. It is mainly determined to fill nitrogen, oxygen and carbon dioxide, two or three mixed gases according to the type of fresh-keeping food. The modified atmosphere packaging machine vacuumizes the air in the original packaging, and then fills a certain proportion of nitrogen, oxygen and carbon dioxide to effectively lock and preserve the fresh food to be packaged.

[Lvgong machinery official website] what is the charge of modified atmosphere packaging machine?

1. Nitrogen

If the fresh-keeping time required by the fresh-keeping food is relatively short, it only needs to be filled with nitrogen. Because nitrogen is an inert gas, it is not easy to react with other substances. It can effectively eliminate the air in food packaging, inhibit the growth of bacteria and provide fresh protection for food. Generally speaking, the modified atmosphere packaging machine is filled with nitrogen, and its preservation cycle is about 5 days. The nitrogen filled in the packaging mainly includes fast food boxed rice and so on.

2. Carbon dioxide

If the preservation time required by the fresh-keeping food is 30 days, the modified atmosphere packaging machine can fill the package with carbon dioxide gas. Many factories will fill the package with carbon dioxide when packaging snacks and bread, so as to ensure that the shelf life of the food is one month.

3. Nitrogen + oxygen + carbon dioxide

If the fresh-keeping food is fresh vegetables and fruits, the modified atmosphere packaging machine can fill the package with a certain proportion of nitrogen and oxygen mixed gas: 90% nitrogen + 5% oxygen + 5% carbon dioxide. Each product is different, and the gas and proportion to be filled are different.

If fresh food is fresh aquatic product, 30% nitrogen +13% oxygen +57% carbon dioxide can be filled in the package of air-conditioned packaging machine. The preservation period is generally 15-30 days. Here we may wonder, why should we fill it with oxygen? Can't you keep fresh only by filling nitrogen and carbon dioxide? In fact, oxygen also plays a great role. It can effectively inhibit the growth and reproduction of microorganisms and make the color of fresh meat look better.

[Wuhan Lugong machinery official website] what is the charge of modified atmosphere packaging machine? In order to maintain the freshness of food and prolong the shelf life of food, the modified atmosphere packaging machine fills the food packaging with a mixture of nitrogen, oxygen and carbon dioxide. It is a common method of fresh locking and preservation. A certain proportion of mixed gas can be added according to the type of your product. In addition, before purchasing modified atmosphere packaging machine, we should make more investigation and comparison. After all, choosing the model suitable for our own products is the top priority.
