Stainless steel PSA Nitrogen Generator Box type , Dew Point -60 to -45 Degree Celsius




Brief Introduction for PSA Nitrogen Generator Principles

When the process adopts lifting air, oxygen and nitrogen have different diffusion rate and adsorptive capacity to separate oxygen from nitrogen on carbon molecular sieve(CMS). When air is compressed to 0.8MPa, air source enters in pressure-swing adsorption tower for separation after being purified through dry and oil-water separation process (filter). Oxygen molecules are diffused and adsorbed in carbon molecular sieve under pressure. Non-adsorbed nitrogen is discharged from outlet of adsorption tower. Oxygen is desorbed, discharged and purged in adsorption tower under depressurization. Moreover, adsorbent can be recycled.

Food Packing

N2 is stable. Nitrogen gas is usually used to drive out the oxygen and to slow down the respiration and the oxidization. Nitrogen gas also can control the growth of the bacteria. Besides, nitrogen gas is water and oil insoluble. The food rarely adsorbs the nitrogen gas, so the package will never collapse. The nitrogen gas used in food industry should be produced under the standard of food security, so it can be produced with the PSA nitrogen making technology and membrane separation nitrogen making technology. With the rapid development of the food packing industry, nitrogen gas is used by more and more food producer.


Modified Atmosphere Packaging of the Dry Food

There is almost no water in the milk powder, coffee, potato chip, cheese, pine cone, peanuts, etc. So, the microorganism can’t grow under this circumstance. The food only goes sour because of the oxidization. For example, the peanuts and the potato chips will go sour because of the oxidization and the laver will change color because of the oxidization. The aroma and the vitamin will go at the same time. The modified atmosphere packaging of these foods should focus on how to inhibit the oxidization of these foods. The widely used technology is vacuum pack with nitrogen. This can lower the oxygen purity gas below 1% so to refrain the oxidization of the food.





Technical Features

1. Only equipped with micro- oil or oil-free air compressor. Open the nitrogen generator and then nitrogen will be generated immediately. The nitrogen purity range is adjustable, the regulating range is 95%- 99.99%.

2. The whole set of machine is automatic and equipped with converter circuit energy-saving control to make the whole nitrogen generator machine operate under a economic, effective state.

3. Nitrogen meter continuously monitoring nitrogen purity online. The structure of the equipment is compact and the size is small, so this machine is easy to clean.

4. This machine is optimal designed and durable, and the investment reclaims fast.
