Shrinkage effect on drying behavior of potato slabs

The rate of drying of potato slabs at different initial moisture contents and thicknesses was investigated. The variation of surface area with time was measured in order to consider the degree of shrinking of the samples during drying. Experimental drying curves were interpreted in terms of Fick...
