The problem of onedimensional heat transfer in finite slabs of freezing food materials cooled from both sides is considered. The authors’ modification to Plank's equation is compared with a numerical scheme. The paper shows that in the important slab freezing problem a simple formula, based on an approximate analytical solution, is at least as accurate as a complex finite difference formulation, and has some substantial practical advantages.
