Abstract:
Computational fluid dynamics (CFD) technology can predicts heat and mass transfer during rapid freezing. In this paper, the immersion rapid freezing of abalone was investigated and computational fluid dynamics technology was employed to establish three-dimension unsteady numerical calculation model of abalone rapid freezing. Solidification model was selected and the polynomial calculation method was developed for calculating abalone thermal properties in order to improve numerical solving accuracy. The distribution of abalone temperature during the freeze process and the relationship between abalone mass and frozen time were got by using CFD technology. It was found that numerical calculation model and the simulation methods for abalone rapid immersion freezing were reliable, which could predicate abalone freeze process and freeze time.
