Résumé

The aim of this study was to validate a mathematical model previously developed for predicting the cooling rate of individual packages of strawberries (clamshells) during an industrial forced-air cooling application. The differences between the predicted and experimental profiles of the average-fruit temperature per clamshell were less than 0.7°C (within the limits of the experimental uncertainty). The 7/8th cooling time of individual clamshells was predicted within less than 3% of the experimental value. In addition, the local performance of the model and its capability to predict the strawberry moisture loss were qualitatively analyzed. The moisture loss was predicted between 73 and 88% of the experimental value. The predicted temperature profile of individual fruits and airflow within clamshells followed the general trends experimentally determined. Finally, the results corroborated that the transport phenomena during force-air cooling applications can be modelled by decoupling the momentum transport from the transport of energy and mass.
