Introduction of Nitrogen Generator for Food Preservation
A full PSA nitrogen generation system needs air compressor, air dryer, filters, air receiving tank, nitrogen generator/nitrogen machine, air buffer tank and nitrogen buffer tank, etc.
Working Principle of Nitrogen Making System
PSA (Pressure Swing Adsorption) is an advanced gas separation technology, which
has an irreplaceable position in the field of current on-site gas supply. PSA nitrogen generators use compressed air as raw materials and carbon molecular sieves (CMS) as adsorbent to get high purity nitrogen based on the principle, which is pressure swing adsorption under normal temperature. In general, use two parallel adsorption towers, which are automatically running with pneumatic valves controlled by PLC, alternatively adsorb under pressure and regenerate without pressure, to separate nitrogen and oxygen, and get final required high purity nitrogen gas continuously.

Food Usage of Nitrogen Generator for Food Preservation
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 flavour 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.
Technical Features of Nitrogen Generator for Food Preservation
1, All technical processes of nitrogen generation and filling technology of molecular sieve are introduced from Germany. Thus can maximize adsorption efficiency and avoid pulverization of molecular sieve, to ensure service life of CMS be more than 10 years.
2, Use imported pneumatic valves, which can work continuously for more than 2,500,000 times without breakdown.
3, Use international famous brands PLC systems, to ensure purity and flowrate of nitrogen gas be long-term stability.
4, Our PSA nitrogen generator has reliable performance, can run average 15,000 hours without breakdown under normal operation condition.
