Abstract:
1. A method for maintaining fresh produce in a near “just harvested” state by (1) filling a sealed truck trailer cargo compartment with Nitrogen while exhausting the existing atmosphere until Nitrogen sensors recognize that the compartment has reached the desired concentration of Nitrogen; (2) scrubbing the atmosphere within the container of any Ethylene that does form by the use of commercially available Ethylene scrubbers; (3) periodically exhausting the atmosphere and replacing it with Nitrogen from a tank within a service compartment; (4) limiting the amount of Oxygen in the cargo compartment through the use of Oxygen sensors and an Oxygen analyzer that will signal a gas control valve and the exhaust port controller to cause the atmosphere to be exhausted through an exhaust ports and replaced with Nitrogen from the tank within the service compartment; (5) limiting the amount of Carbon Dioxide in the cargo compartment through the use of Carbon Dioxide sensors and a Carbon Dioxide analyzer that will signal the gas control valve and the exhaust port controller to cause the atmosphere to be exhausted through the exhaust ports and replaced with Nitrogen from the tank within the service compartment.
