Law enforcement fick and peleg model for study of water uptake in navel cargamanto yellow (phaseolus vulgaris l.) and peas seca (pisan sativa) during rehydration

Abstract

This research validated Fick’s Law and Peleg’s model applicability for modeling water sorption of yellow navel cargamanto bean (Phaseolus Vulgaris L.) and dry pea (Pisum sativum), using five different water temperatures 25, 35, 40, 47 y 55 ºC, to soak the analyzed materials; for bean an optimal mathematical expression was obtained to make estimations, opposite case was the observed thing for pea; the diffusion coefficient calculated were all of the order of 1.91 x 10-9 m2/s for bean and 3.51 x 10-10 for dry pea; the activation energies were 41.464 KJ/mol for bean and 56.246 KJ/mol for dry pea
