Abstract: Methods, apparatus, and system to measure and control respiration of a perishable commodity in a vacuum chamber, including for purposes of extending a shelf life of a perishable commodity therein, including.

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.

Abstract: Methods, apparatus, and system to manage an atmosphere and/or an antimicrobial inside a vacuum chamber or container, including via at least one of valves, sensors, manifold, antimicrobial delivery unit, antimicrobial sachet, vacuum pump, and an atmosphere control.

Abstract: A system and method for storing perishable items under controlled atmospheric conditions is provided. Total atmospheric pressure within a vacuum chamber containing the perishable items is reduced to below a predetermined total pressure limit. Oxygen partial pressure within the chamber is monitored. When the Oxygen partial pressure falls below a predetermined lower Oxygen partial pressure limit, an Oxygen-containing gas is admitted to the vacuum chamber to raise the Oxygen partial pressure above the lower Oxygen partial pressure limit. Total atmospheric pressure within the chamber is also monitored. When the total atmospheric pressure reaches or exceed the predetermined total pressure limit, total pressure within the vacuum chamber is once again reduced below the predetermined total pressure limit.
