Abstract
A method and system in which an oxygen concentrator, which removes O2 from ambient air and exhausts the oxygen-depleted, nitrogen-rich air, is used in combination with an enclosed cargo storage or transportation container to replace the oxygen-rich ambient air within the container with nitrogen-rich ambient air that will retard spoilation of cargo that is prone to oxygen-induced spoilation, such as fruits and vegetables.
Claims15
A system for retarding spoilation of cargo that is prone to oxygen-induced spoilation, the system including:
- a. a cargo container that is capable of storing cargo, the cargo container not being open-air to the surrounding environment;
- b. an oxygen concentrator that is operable to intake ambient air which includes both oxygen and nitrogen;
- c. said oxygen concentrator located within said cargo container in fluid communication with the ambient air with said cargo container;
- d. said oxygen concentrator being powered by any conventional means;
- e. said oxygen concentrator having an intake port through which the ambient air within said cargo container is drawn into said oxygen concentrator;
- f. said oxygen concentrator operable to separate oxygen from said ambient air and vent the oxygen to the exterior of said cargo container;
- and
- g. returning the now oxygen-depleted, nitrogen-rich air to an interior of said cargo container.
A method for retarding spoilation of cargo that is prone to oxygen-induced spoilation, the method including:
- a. in a cargo container that is capable of storing cargo, the cargo container not being open-air to the surrounding environment, providing an oxygen concentrator that is operable to intake ambient air which includes both oxygen and nitrogen and to substantially remove the oxygen from the ambient air;
- b. providing venting connected to said oxygen concentrator such that the oxygen-rich air is exhausted to the exterior of said cargo container, and the nitrogen-rich air is returned to an interior of said cargo container;
- and
- c. maintaining continuous operation of said oxygen concentrator such that oxygen content of the air within said cargo container is maintained to the desirable and pre-determined level during storage of the cargo in said cargo container.
