Tea fresh-keeping nitrogen generator is a special small commercial gas production equipment developed for tea processing, packaging and storage scenarios. Tea is rich in polyphenols, vitamins and other active substances, which are easy to oxidize and deteriorate when exposed to oxygen, resulting in discoloration, taste deterioration and reduced shelf life. Nitrogen filling and oxygen isolation is the most mainstream and safe tea fresh-keeping technology in the industry. The small commercial nitrogen generator can continuously produce high-purity nitrogen to replace the air in tea packaging bags and storage containers, inhibit tea oxidation and microbial growth, and effectively maintain the color, fragrance and taste of tea during storage and transportation.

The tea fresh-keeping special nitrogen generator mainly adopts mature PSA pressure swing adsorption technology, with compact equipment structure, simple operation and low operating cost, which is suitable for small and medium tea processing factories and tea packaging workshops. The equipment can stably produce nitrogen with a purity of 99.5%-99.9%, which fully meets the tea fresh-keeping standard. High-purity nitrogen can isolate oxygen and moisture, prevent tea from mildewing, discoloring and odor changing, and greatly extend the shelf life of green tea, white tea, longjing tea and other easy-to-oxidize teas. Different from industrial high-purity nitrogen equipment, the tea fresh-keeping generator is optimized for food-grade application, with no pollution in the gas production process and no harmful residue, meeting food safety production specifications.

In terms of use advantages, small commercial tea fresh-keeping nitrogen generators have outstanding cost and applicability advantages. The equipment realizes on-site self-production of nitrogen, completely replacing expensive bottled nitrogen, reducing the fresh-keeping cost of tea enterprises by more than 60%. The full-automatic operation design does not need special personnel on duty, and the equipment can work continuously for 24 hours to match the tea packaging production line. The miniaturized body design saves workshop space, and the low-noise operation will not affect the production environment. For household tea storage and small batch tea fresh-keeping scenarios, portable small nitrogen generators can also be selected, which are flexible and convenient to use, and are the best supporting equipment for modern tea green preservation and quality maintenance.
