Product Description
According to the principle of variable pressure adsorption, the food nitrogen machine adopts high quality carbon molecular sieve as the adsorbent, in a certain mechanical effect, the oxygen diffusion rate in the carbon molecular sieve microporous is much larger than the nitrogen, when the adsorption does not reach equilibrium, the nitrogen is enriched in the gas phase, forming the finished nitrogen gas. Then the pressure is reduced to atmospheric pressure, and the adsorbent desorbs the oxygen and other impurities adsorbed to achieve regeneration. Generally, two adsorption towers are set up in the system, one for nitrogen production and the other for desorption and regeneration, which are automatically controlled by PLC program to make the two towers work in alternating cycles to achieve the purpose of continuous production of high-quality nitrogen gas. Under pressure, clean and dry compressed air is used for pressurized adsorption, decompression and disassembly in the adsorber.

Process description.
(a) Air compression section: air compressors, air storage tanks.
(a) Air purification section: high-efficiency degreaser, precision filter, compressed air dryer, air buffer tank, activated carbon filter.
The main part of the nitrogen machine: adsorption tower, PLC controller, nitrogen dust filter, nitrogen storage tank, using compressed air as raw material and power, through variable pressure adsorption to produce nitrogen with a purity of 95% to 99.9995%.
Nitrogen purification section: 99.9% of the total nitrogen is purified by using a carbon load purifier (hydrogen purifier) to obtain high purity nitrogen (99.999% to 99.9995%).
Due to the chemical inertness of nitrogen, it is often used as a protective gas. So often used for food storage, food packaging, tire inflation, etc. Used in food packaging to prevent oxidation, mold and mildew, thus extending the shelf life of food. Inflation of the tires improves safety, increases comfort and reduces the chance of a flat tire.
Food Industry Applications
1, more used for bread, cake and other perishable food packaging, nitrogen into the food packaging bags, so that the food is surrounded by nitrogen, not only will not lead to food in storage and transportation by extrusion deformation, oxygen-free state will also let the shelf life of food greatly extended.
