Air-freight coolchain improvements using insulation and supplemental cooling.

 

Four main treatment combinations, using an insulated pallet wrap (foil, or a proprietary cover, Coolguard) and ice or dry ice as a supplemental coolant, were evaluated for their ability to slow the warming of cooled air-freighted products. Experiments were conducted in a controlled temperature room using 450 kg asparagus pallets. Temperatures were monitored at various locations in the pallets and weighted average temperatures calculated for each run. Each treatment was evaluated by fitting a logarithmic warming function, for comparison with other treatments. Average U-values for both wrap systems were calculated. The greater benefit of the wrap was the elimination of air exchange. Benefit of the supplemental cooling were comparatively small. No significant differences were found between the two wrap treatments.
