Abstract
The apparatus is for pre-cooling produce immediately after harvesting of the same and towards this end, constitutes a portable elongated enclosure normally positioned at the field site of harvesting. A detachable dolly supports the enclosure so that it can be moved to various different field sites as required. The enclosure itself supports pallets having containers arranged in two longitudinal rows to define a passage therebetween. An air handling housing in turn incorporates an exhaust fan, cooling coils and appropriate ducting so that refrigerated air is circulated over the tops and sides of the rows of the containers and drawn into the central passageway by the exhaust fan to then again pass into the air handling housing. In other words, a forced air circulation is used to remove the field heat from the containers.
