Résumé

A model for predicting the dynamic product heat load and weight loss during beef chilling has been developed using the finite difference method, in which the irregular beef geometry is approximated by a combination of seven cylinders and slabs. The model was tested against data from 55 industrial beef chilling trials covering a wide range of carcass size, fatness and chilling conditions. The predicted heat removed during the first 2 hours in the model was on average 0.0194 kilogrammes (0.00046%) higher than the experimental value. Improvements in accuracy would probably have arisen if slaughter floor and chiller conditions had been more accurately known. The model allows for time-variable chiller conditions, making it widely applicable to meat industry applications.
