Food grade nitrogen generator is special nitrogen production equipment strictly developed in accordance with food safety production standards, dedicated to nitrogen supply in food processing, packaging, fresh-keeping and storage links. Food-grade nitrogen, as a safe food auxiliary gas, is colorless, odorless, non-toxic and inert, which can effectively isolate oxygen, inhibit bacterial reproduction and prevent food oxidation and deterioration. Different from ordinary industrial nitrogen generators, food grade models adopt food-level purification and filtration systems, which can completely remove moisture, oil, dust and harmful impurities in the air, ensuring that the produced nitrogen meets food safety grade standards and does not cause any pollution to food products.

In terms of technical configuration and safety performance, food grade nitrogen generators adopt multi-stage precision filtration and high-efficiency drying treatment technology, equipped with primary, secondary and high-efficiency oil removal filters and low-temperature drying systems. The equipment uses food-grade safe materials for all gas-contact parts, avoiding chemical precipitation and secondary pollution. The PSA nitrogen separation technology adopted has stable performance, which can stably produce nitrogen with purity of 99.9%-99.999%. The nitrogen has high purity and no impurity gas, fully meeting the fresh-keeping and anti-corrosion needs of baked food, snack food, fried food, fruits and vegetables, and frozen food. At the same time, the equipment is equipped with a real-time purity monitoring system, which can automatically alarm and adjust parameters when the nitrogen purity is unqualified to ensure 100% qualified gas supply.

In terms of application advantages and industry value, food grade nitrogen generators realize on-site safe and efficient nitrogen supply for food enterprises, replacing traditional bottled food nitrogen. It not only reduces the repeated procurement and transportation costs of enterprises, but also avoids the safety risks and gas quality instability caused by external gas supply. The equipment has a fully closed automatic operating system, clean and hygienic operating process, no pollution emission, and meets food factory dust-free and sterile production environment requirements. It is widely used in food modified atmosphere packaging, nitrogen-filled fresh-keeping, grain and oil storage, beverage nitrogen filling and other scenarios, effectively extending the shelf life of food, reducing food waste, and helping food enterprises achieve standardized and safe production while improving product quality and market competitiveness.
