ABSTRACT:
A storage device for the preservation of oxidizable materials is provided. The storage device includes a storage chamber enclosing a storage space where oxidizable materials may be placed and a differentially permeable membrane. The differentially permeable membrane allows at least one selected gas to pass therethrough while inhibiting at least oxygen from passing therethrough. The differentially permeable membrane is in fluid communication with the storage chamber such that the at least one selected gas is allowed to pass through the differentially permeable membrane flows into the storage chamber. An air mover, preferably a compressor, feeds gases to the differentially permeable membrane. A cooling element is provided for cooling the temperature within the storage chamber below that of the ambient temperature. The level of oxygen within the storage chamber is thus reduced relative to the level of oxygen in the atmosphere.
