Abstract

Experiments conducted on a rectangular slab of fish muscle with heat transfer through one surface result in freezing times which are adequately predicted by the Nagaoka, et al. modification to the Plank solution for the freezing time of an infinite slab. Neumann's exact solution to the Fourier heat conduction equation results in freezing times which progressively overestimate experimental times with increasing Biot number. Using the Nagaoka, et al. formulation, formulae are obtained for the freezing time, in terms of weight, of irregularly shaped commercial fish fillets. With the aid of such relationships, an analysis is made of a commercial freezing process with a view to optimizing the production rate.
