Numerical simulation and microtomography study for drying a deformable isodiametric-cellular food

Abstract The aim of this work is the simulation volumetric strain tuberous crop during drying. We propose a poroelastic model for predicting drying kinetics and volume loss potato cubes convective Biot’s theory poroelasticity was used, which considers Lamé parameters, Young’s modulus Poisson’s ratio. Drying were modeled compared versus experimental data. An X-ray microtomograph coupled with image analysis used to visualize shape size samples experiments conducted at 50, 60 70 °C, 20% RH, an air velocity 1 2 m/s. process interrupted several times perform tomographic acquisitions. found period ideal shrinkage, nevertheless, reveals kinetic behavior over time. computes strain, describes correctly data obtained by microtomography.
