Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 4 (Fevrier 2010) . - pp 1986–1990 Titre : Drying model for calcium alginate beads Type de document : texte imprimé Auteurs : Lyn, Margaret E., Auteur ; Ying, DanYang, Auteur Année de publication : 2010 Article en page(s) : pp 1986–1990 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Calcium  alginate  beads. Résumé : The dehydration of calcium alginate beads is observed to have a simple power-law time dependence. The ratio of the water content, M(t), to the initial water content, M0, can be expressed as The parameter tc is insensitive to the guluronic content of the alginate or the degree of cross-linking. Using this simple model, tc can be estimated from the properties of water vapor, the initial water content, and the relative humidity, in addition to an empirically derived correction factor, K, which has been found to be 2.8 ± 0.3.
