Nitrogen Generator for food industry are generally equipped with two adsorption towers in the system. One tower absorbs nitrogen to produce nitrogen, and the other tower desorbs and regenerates. It is automatically controlled by a PLC program, and it is necessary to replace the two towers. The finished product will then pass through the Stirling refrigerator to produce liquid nitrogen as scheduled. And according to the principle of pressure swing adsorption, high-quality carbon molecular sieve is used as the adsorbent, and nitrogen is produced from the air under certain circumstances. By purifying dry compressed air, pressurized adsorption and decompression desorption are performed in the adsorber. Because of the kinetic effect, the dispersion rate of oxygen in the pores of carbon molecular sieve is much higher than that of nitrogen. When the adsorption does not reach equilibrium, nitrogen is enriched in the gas phase to form the product nitrogen. Then, the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration.
