海报摘要

The moisture diffusion coefficients of potatoes were determined at three temperature levels neglecting and taking into account the shrinkage associated to the drying process. The methodology chosen for the diffusion coefficient estimation when the associated shrinkage is taken in account is based in a non-linear estimator (a Luenberger estimator). An Arrhenius type expression for the diffusion coefficient as function of temperature is proposed. The results obtained without taking into account the volume reduction are compared with those obtained when the volume reduction is considered.
