Abstract

Abstract:

Finite element analysis was used to simulate the effects of cool air temperature and velocity on the pre-cooling process of longan in a small packing box in order to explore the temperature profile of longan located at different space positions. The simulated data agreed with the experimental ones well. The biggest temperature difference between the simulated and the experimental data was around 3.5 ℃. When the cool air velocity used was 1 m/s, longan cooled rapidly and less energy was consumed and the 7/8 cooling time required was at least 35 min at 5 ℃ cool air temperature.

Key words: longan, pre-cooling, model, numerical simulation
