Abstract
This paper presents a finite element analysis of the process of freeze -drying in a coffee sample. The numerical model which has been develop ed was based upon the Luikov system of partial differential equations which calculates the distribution of temperature, moisture potential a nd pressure within a capillary-porous body. The position of the frozen /dried interface is calculated from the temperature gradients either s ide of the sublimation front within the coffee sample.
