Modular nitrogen generator for food and beverage preservation

Human beings have increasingly high requirements for food, and food safety is of paramount importance. The preservation of food and the storage requirements for food and grains are also becoming increasingly stringent. The protection of nitrogen not only extends the warranty period, but also maintains a fresh taste. The application of nitrogen gas modified packaging can greatly increase the possibility of long-term specific transportation The GZN series modular nitrogen generator adopts pressure swing adsorption technology, using air as the raw material and selecting qualified adsorbents. Under a certain pressure, the adsorption capacity of the adsorbent for oxygen is much greater than that of nitrogen. By controlling the opening and closing of the pneumatic valve through a programmable program, the adsorber is controlled to cycle alternately, perform pressure adsorption and pressure reduction desorption, and complete the separation of oxygen and nitrogen to obtain the required purity of nitrogen.
