Introduction of High Purity Psa Nitrogen Generator for Food Packaging

The whole nitrogen generation system consists of air compressor, air dryer, precision filter system, PSA nitrogen generator, air storage tank and nitrogen storage tank.

Air compressor: It is the main body of feed air device, to provide feed air for pressure

swing adsorption oxygen-nitrogen system at certain pressure and flowrate.

Air Dryer: The compressed air after passing the pipeline filter enters into air dryer. The function of air dryer is to cool the compressed air to be about 5℃. The water vapor in the air is condensed into liquid water, it is separated and filtered by moisture filter and then discharged through blow-down valve. The atmospheric dew point of compressed air is up to about -20℃.

Nitrogen Generator: Oxygen and nitrogen separation system is the main part of nitrogen generator and composed of two adsorption towers (filled with carbon molecular sieve), pneumatic valve, silencer and stop valve. When the pressure increases, one adsorption tower absorbs oxygen and generates nitrogen, while the other absorption tower conducts deoxidation and regeneration by depressurization. Nitrogen is continually generated by this alternate cycle.

Machine Application

1) Beer, wine, fruit spirit and edible oil: use N2 for holding tank, bottle blowing and before closing capsule to remove O2. It can prevent oxidation, spoilage and fading of noncarbonated beverage and edible oil.

2) Puffed and fried food: N2 can prevent food fluffy and flavor reversion caused by little water in the bags. N2 also can make the shape and package beautiful, and food will not be crushed in transportation. 

3) Pastry, bakery food and vitellus-pie: Flushing N2 inside the food bags can prolong freshness time and prevent food being metamorphose and crushed in transportation.

4) Milk Powder and soyabean milk powder: just use little N2 can prevent or reduce agglomerate phenomenon of milk powder caused by long-time extrusion storage.
5) Cereal, nut, fruit and vegetable: Flushing N2 can prevent pests harming, and saving little O2 can reduce breathing rate of fruit to make the fresh effect more obvious.

6) Candy and snack foods: N2 is mainly suitable used in the airtight food bags.
