Abstract: An improved system and method for evaluating stored agricultural or horticultural commodities is provided. The system and method generally include performing atmospheric measurements within multiple controlled atmosphere rooms, or sampling enclosures coupled to controlled atmosphere rooms, and determining a change over time of a respiratory value of the commodities stored therein. Based on the change over time of the respiratory value, the system and method selects commodities from among at least one of the controlled atmosphere rooms for delivery, marketing, storage, or other disposition.

Abstract: A pressure control system for a CA room including a bladder and an active displacement control that are operable to control the internal pressure of the CA room through variations in displacement. The system may include a controller configured to vary the displacement of the bladder based on the difference between barometric pressure and CA room internal pressure. The system may control bladder displacement based on the output of a differential pressure sensor that measures the pressure differential between the CA room and barometric pressure, or the output of separate internal and external sensors that separately measure CA room pressure and barometric pressure. The bladder may be an inflatable bladder and the active displacement control may inflate and deflate the bladder to vary its displacement within the CA room. The active displacement control may include an active air supply with a blower that can quickly inflate and deflate the bladder.
