Résumé

A three-dimensional numerical heat transfer model formulated through a combined fully implicit (FI) and Crank-Nicolson (C-N) schemes was validated with freezing of shrimp and Tylose blocks carried out in a laboratory freezing of a computer program based on a single algorithm. The C-N scheme provided an accuracy of prediction better than the FI scheme for all the freezing conditions and with Tylose blocks. Prediction by C-N model (5.6-13.2%) in case of shrimp blocks. The correlation coefficient between the experimental and predicted temperature during shrimp block freezing was better with C-N model (0.95-0.97) than that with FI model (0.93-0.95). Similar results were obtained with Tylose blocks.
