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...

description The rate of drying of potato slabs at different initial moisture contents and thicknesses was investigated.

Experimental drying curves were interpreted in terms of Fick's law for shrinking bodies and by means of the classical diffusional model, without shrinking. It was found that for relatively short drying time Fick's model with shrinking correlates adequately with the experimental results, with a diffusion coefficient independent of moisture content. Howerver, in terms of the classical diffusional model the experimental data predict a strong dependence of the diffusion coefficient on moisture content.
