Drying kinetics and effective water diffusivities in olive stone and olive-tree pruning

Drying kinetics of olive stone and olive-tree pruning, two important biomasses from olive culture, was experimentally assessed at six different temperatures (from 343 K to 393 K) and four sample thicknesses (from 15 to 50 mm). Analysis of the drying curves revealed that Page's model was suitabl...
