Studied the temperature distribution of strawberry during commercial forced air pre-cooling, quantifies the relationship between environment and product temperature, and evaluated the pre-cooling duration. Results: the half-cooling time (HCT) inside the pre-cooled tunnel was about twice the external semi-cooling time, and the HCT outside the tunnel was closely related to the internal HCT. The temperature prediction from a limited number of sensors detected a temperature change of up to 7 ℃ at the end of pre-cooling, indicating that in some cases the pre-cooling time should be extended to increase the uniformity of the cooling temperature.
