Claind is an Italian company leading the world market in the manufacture of gas generators. For use in the food processing industry, the company developed a variety of solutions for the production of food-grade nitrogen, in compliance with EC standards and ensuring the quality of food-grade nitrogen E 941. The agro-industry uses nitrogen for a variety of applications, as for instance the protective atmosphere food packaging; different production steps of wine and bottling; pressurization of still mineral water; preservation of fresh fruit and vegetables. The packaging with nitrogen extends the shelf-life of food products up to five times compared to conventional packaging. In fact, nitrogen contributes to preserve the freshness, while maintaining the colour, shape and texture of the packaged good. By using nitrogen, the treatment with chemical-physical stabilizers can be avoided, thus maintaining organoleptic properties of food. All Claind generators offer following features: high nitrogen purity levels thanks to the PSA technology (Pressure Swing Adsorption); membrane switches for entering operation parameters; oxygen analyser for the real-time display of the nitrogen purity level; unattended autonomous operation for 24 hours a day, 365 days a year.
