The work aims to accurately predict the airflow distribution and heat and mass transfer process inside fruit ventilated package. A 3D forced-air cooling numerical model including package wall, tray and fruits was developed. Fluent was employed to simulate the velocity and temperature distribution in carton, and the reliability of model was validated by comparing with experimental results. There was a good agreement between the simulated and experimental results, and the maximum average relative error and root-mean-square error were 12.2% and 1.34 ℃, respectively. Due to the large amount of cooling airflow through first layer of stacked apples close to the vent position, the pre-cooling time was nearly 35.6% shorter than that in the second layer from initial temperature to the same target temperature. This model can be used as a reference to study airflow distribution and heat and mass transfer inside ventilated package. The vents should be evenly distributed on the windward side of package to ensure the cold airflow through each fruit layer uniformly.
