3.3.1.3. Effective water diffusivity
As the drying is a water removal process, so the diffusion of water and starting accessibility during the
drying were studied as well. Fig. 7 illustrated the impact of DIC operating parameters (saturated steam
pressure and thermal holding time with constant initial water content) on effective water diffusivity during
drying. The obtained results showed that both saturated steam pressure and thermal processing time had
significant impacts on effective water diffusivity; the higher the saturated steam pressure, the higher the
effective water diffusivity within the product under intensified drying conditions.
