A new experimental device to monitor mass and dimensions of samples during convective drying
Résumé
This article presents the results obtained from an experimental device designed for
the accurate determination of hygroscopic and dimensional properties during convective
drying. During drying, the mass and dimensions of the sample are continuously measured
with a suspension magnetic balance and a digital camera, respectively. Experiments were
carried out on cylindrical samples of potatoes. Three drying kinetics were tests. Potato
samples showed values of isotropicity always around 1.2, meaning that shrinkage was slightly
more important in the longitudinal direction.
