Abstract

A solution is obtained for the transient temperature distribution and the position of the sublimation front for freeze-drying slabs, cylinders, and spheres. The surface is exposed to thermal radiation boundary conditions so that the surface temperature is time dependent. Results, presented in dimensionless form, cover a wide range of variables that should include essentially all food products.
