The commercial nitrogen generator specially used for nitrogen filling and fresh-keeping of food nuts is a professional food-grade gas supply equipment developed for the fresh-keeping, anti-oxidation and shelf-life extension needs of nut products such as walnuts, almonds, cashews and pine nuts. Nut foods are rich in unsaturated fatty acids, proteins and vitamins, which are extremely prone to oxidation and deterioration when exposed to oxygen in the air, resulting in rancidity, discoloration and taste deterioration. At the same time, the humid air environment is easy to cause nuts to absorb moisture and mildew, seriously affecting product quality and shelf life. Different from industrial nitrogen equipment, this special nitrogen generator strictly follows food safety production standards, adopts non-toxic, harmless and pollution-free purification materials, and can provide food-grade high-purity nitrogen that meets national food processing safety specifications.

The equipment adopts efficient PSA nitrogen generation technology, with simple operation, stable performance and low operating cost, which is very suitable for commercial food processing factories, nut packaging workshops and food production enterprises of different scales. The nitrogen produced by the equipment has high purity and low oxygen content. Filling nitrogen into nut packaging bags can effectively exhaust the air in the packaging container, isolate the contact between nuts and oxygen and moisture in the air, inhibit the reproduction of mold and bacteria, and prevent fat oxidation and moisture deterioration of nuts. Compared with traditional vacuum packaging, nitrogen-filled fresh-keeping can not only maintain the crisp taste and original flavor of nuts, but also play a buffering and anti-extrusion role, avoiding nut breakage and shape damage during transportation and sales.

This commercial nitrogen generator is designed with a miniaturized and integrated structure, occupying a small area and being easy to install and deploy. It supports continuous nitrogen supply for assembly line packaging operations, with stable gas output pressure and adjustable flow rate, which can adapt to different nut packaging specifications and production speeds. The whole machine has no vulnerable parts with high loss, low failure rate and long service life, and the on-site nitrogen generation mode replaces the traditional bottled nitrogen purchase mode, greatly saving the long-term gas purchase cost for food enterprises. It is not only suitable for nut fresh-keeping and nitrogen filling, but also widely used in the fresh-keeping packaging of puffed food, dried fruits, tea and other food products, which can effectively extend the shelf life of products and improve market competitiveness.
