Freshly harvested vegetation is precooled in refrigerated containers by circulating 25,000 cubic feet of chilled air per minute through the container. Conduits formed by pallets on which boxes of the vegetation are stacked distributes the chilled air, which flows through the produce to the top of the refrigerated container. Air is withdrawn from the top of the container and cooled by flowing it past large chilled water film surface area produced by cascading 2,200 gallons of water per minute through a cross fluted PVC surface media block. A drift eliminator removes water droplets that might damage vegetation or cardboard boxes from the chilled air exiting the surface media block. A radial fan recirculates the rechilled air to the conduits below the pallets. A false door is movably mounted to fluidly connect the air flow at appropriate positions on the container.
