Abstract
Systems, methods, and apparatus for storing perishable items under reduced pressure conditions. Total atmospheric pressure within a vacuum chamber containing a perishable item is reduced below a total pressure limit. Oxygen partial pressure and total pressure within the vacuum chamber are monitored. When oxygen partial pressure falls below a lower oxygen partial pressure limit, an oxygen-containing gas is admitted to raise oxygen partial pressure above the lower oxygen partial pressure limit. When the total atmospheric pressure reaches or exceeds the total pressure limit, total pressure is once again reduced. The vacuum container or chamber comprises a section of cylindrical pipe open at both ends, a first end cap and a second end cap, and formed of a plastic material. Notwithstanding that the pipe and end caps are formed of plastic, they are formed with a structure capable of withstanding pressure created by a high vacuum in the vacuum container.
