International Classification:

A23B 700

US Classification:

99475, 62 78, 62329, 99467, 99476, 99517

Abstract:

Apparatus for delivering conditioned air from the mixing chamber of a mobile container into a pair of supply air plenums that extend rearwardly along the side walls of the container. A series of fan units are contained within pods located within the mixing chamber adjacent to the front end of each supply air plenum. The pods are stacked in vertical alignment from the floor of the container to about the height of the container ceiling. Each pod includes two fan units that are contained in separate compartments. Each fan unit can be removed easily from the compartment and each pod unit can similarly be removed separately from the stack to facilitate mounting and removal of the pods as well as the individual fan units.

Abstract:

An enclosed mobile container having a refrigeration unit for providing conditioned air to a mixing chamber located at the front of the container. Air penetratable cartons containing perishable produce are stacked in rows along the length of the container to create a pair of supply air plenums running along each side wall of the container and a return air aisle running along the center of the container. A gas generator is mounted in the mixing chamber to add a ripening agent to the conditioned air. Fans force the supply air from the mixing chamber into the plenums under pressure so that the supply air is passed through the cartons into heat transfer relationship with the produce and the air is returned to the mixing chamber via the center aisle. A fresh air exchanger is mounted in the container for venting the ripening agent to ambient after the completion of a ripening cycle.
