Principle of operation.
The food grade nitrogen machine is based on the principle of variable pressure adsorption, using 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 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.
Mainly used in food packaging, food preservation, food storage, food drying and sterilization, pharmaceutical packaging, pharmaceutical replacement gas, pharmaceutical delivery atmosphere, etc.
