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.

Why Nitrogen Generator is good for Food, Beverage & Cereal Industries?
Because nitrogen has the features of inactive and not easily breeding bacteria under normal temperature, can fully keep foods' color, smell and taste, and the storage quality is much better thenmechanical cold warehouse storage.
1) Food package Traditional vacuum package is rapidly replaced by nitrogen-filling package, which is applied in package of fired food, puffed food, bakery food, and fresh slices of various farm products, special cheese and fresh meet. Because nitrogen-filling package can more effectively maintain taste and nutrition of foods, it is expected to further develop its application. Because oxidation action is generated by involving in O2, It causes microbe and bacterial reproduction and leads to food spoilage and deterioration. As a kind of suffocating inert gas, N2 can suffocate and inhibit bacterial reproduction. The aim of using N2 is to purge O2, relieve oxidization and respiration of foods. Moreover, N2 has low solubility in water and grease. And foods have small adsorption effect on N2. Therefore, N2 can be used as a good gas for preserving foods and keeping foods fresh. In addition, nitrogen-filling package can effectively protect the shape of food in package; Prevent crumbly food from being crushed; Avoid packed food adhesion together under pressure due to unbalance between interior and exterior
Pressures; Avoid food packed food stiffening. Although food has irregular shape, beautiful shape of package can be maintained in order to avoid food deterioration caused by damaged package due to surface folding.
2) Beverage Mixture Oxygen dissolved in liquid and oil can cause precipitation. Oxygen existing in beverage can make the taste become bad and shorten its life. Gaseous nitrogen is conveyed in liquid during processing by applying a kind of method known as "mixture" (liquid is mixed by compressed air through sprayer). These nitrogen bubbles can remove oxygen in order to
Prevent non-carbonate beverages (fruit juice, tea and milk) and edible oils (peanut, olive, sunflower and rape oils) from being oxidized, deteriorated and faded.
3) Nitrogen Expansion For other foods, it is required to add gas for increase food volume. Nitrogen is used to puff edible oils, mayonnaise, margarine in barrel or peanut oil products for increasing their volumes and expansibility, so as to
Prolong their life.
