Food Nitrogen Machine 
 
HL-WG-Food Nitrogen Machine
Principles:
N2 and O2 all have a quadrupole, for the reason that the quadrupole of N2 is bigger than the quadrupole of O2, the adsorption capacity by molecular sieve to N2 is stronger than O2. When the compressed air in certain pressure flow through adsorption bed formed by molecular sieve, the N2 gas is absorbed and O2 is obtained by separation.
The main part of O2 generator is two towers filled with molecular sieve, when the compressed air get into adsorption tower, the N2 is absorbed by molecular sieve, O2 is produced from the export terminal. When one tower produces O2, another tower release the N2 by reducing the pressure to get the renewable desorption of carbon molecular sieve. Two towers alternate adsorption and regeneration to output O2 continuously. 
Features:
 
1.The purity of N2 could be regulated between 95% to 99.9% according as users need;
 
2. Dryness and low dew point of N2 would be conducive for food preservation;
 
3. Low cost, high return, investment recover soon;
 
4. Compact appearance, small area, ease to clean for satisfying the high cleanliness     requirements of the food industry;
 
5. Mature technology, high-quality accessories, durable product.
 Application of Food Nitrogen Generator
Its suitable to use in package and nitrogen package of fruits, vegetables, flowers, tea leaves and puffed food, custard pie, milk bread, European-style egg roll, various cookies, farm products and local special products, such as rice, seed and chestnut, etc.
