Title

An Adsorption-Sublimation Model for a Freeze Dryer

Abstract

A model has been constructed using material and energy balances in the dried and frozen regions of a material undergoing freeze drying. Both sublimatio and adsorption are accounted for in the set of coupled non-linear partial differential equations that constitute the model. Numerical solutions to thes equations are shown to agree quite closely with experimental data over the entire drying period.
