Abstract
Apparatus for aiding in the ripening of produce that includes a sealed container having a refrigeration unit for supplying conditioned air for cooling produce stored in a container. A gas generator is arranged to mix a ripening gas with conditioned air within the container. A fresh air exchanger is integrated into the refrigeration unit for venting conditioned air from the container to ambient and exchanging the vented air with outside fresh air. The fresh air exchanger is automatically operated by a controller which coordinates the cycling of the gas generator with the exchange of fresh air so that the ripening process can be closely regulated.
