The Invisible Guardian of Freshness—The Critical Role of Nitrogen Generators in The Food Packaging Industry In the food industry, nitrogen generators are becoming essential equipment for ensuring food safety, extending shelf life, and enhancing economic efficiency. Using pressure swing adsorption (PSA) technology, they separate high-purity nitrogen (99%-99.999%) from air, providing an inert gas barrier for food processing, packaging, and storage. This fully replaces traditional bottled nitrogen or liquid nitrogen, achieving cost savings and improved efficiency. The following are their key applications and values:
