Why the Milk Powder Cans Need Infilling Nitrogen?
First,
let’s take a look at what is nitrogen:
Nitrogen, the chemical formula N2, under normal circumstances is a colorless and odorless gas. The nitrogen in general is smaller than the air density, but very close. Nitrogen accounted for 78.08% (volume fraction) of the total atmosphere, which was the main component of air. Nitrogen chemistry is not active, at room temperature is difficult to react with other substances, it is often used to make preservatives. But in the high-temperature, high-energy conditions can be chemical changes with some substances used to make useful new substances for humans.
Therefore,
we are not difficult to find, why the milk powder cans need infilling nitrogen:
- Nitrogen is a very stable inert gas. And milk powder composition contains a lot of protein and other easily decomposed nutrients. In order to maximize the nutritional content of milk powder, milk cans filled with nitrogen can effectively prevent protein oxidation;
- Nitrogen is an inert gas. 78.08% of the atmospheres are nitrogen. Not have any toxic side effects, on human health without any side effects;
- The nitrogen density almost closes with air density. It is easy to obtain, easy to fill. In general, nitrogen can be separated by cold air separation, and so on.
From the above three points can be seen, in the milk powder cans need infilling nitrogen mainly in order not to affect the composition of the milk powder. Extend the shelf life of milk powder. Preserving fresh, and prevention metamorphism of milk powder.
Our company independent research and development of the vacuum infilling nitrogen sealing machine. This machine used of the four patented technology. Vacuum, infilling nitrogen and sealing, one machine to complete. Reliable quality, simple operation, smooth operation, high degree of automation. Applicable to all kinds of tin cans, aluminum cans, plastic cans, paper cans and other circular specifications cans, first vacuum and then filling nitrogen, then sealing. And, all pneumatic components are used in international brands, after-sales service and some protection.
