Calculation of Biological Material’s Shrinkage during Convective Drying Using Fractal Model

Abstract:

The unsaturated biological material is divided into the wetting phase and the non-wetting phase, the diffusion of which has the characterization of fractal. In this study, we developed a simple wetting region model to calculate the local moisture content using the box-counting method during the drying process. A new constitutive relationship was derived to determine the unsaturated porous biological material’s shrinkage with the local moisture content and the fractal dimension of the wetting phase. The volume change was linearly correlated with local saturation with larger correlation coefficient, so the new mathematical model is more accurate than others.
