NITROGEN GENERATOR AND STORING METHOD OF FOOD STORAGE

摘要

A nitrogen generator and a method for storing of a food storage are provided to maintain concentration of nitrogen uniformly. A nitrogen generator includes a nitrogen generating unit discharging extracted nitrogen in air. The nitrogen generating unit comprises the followings: two or more nitrogen outlets(271,272) discharging the nitrogen; a valve opening and closing the nitrogen outlet; a membrane flowing the air passed through a compressor; a pressure sensing unit(210) sensing pressure of the nitrogen discharged from the Membrane; and a control unit controlling the compressor.
