Isosteric Heats of Water Vapor Sorption in Two Castor Varieties [PDF]
Journal of Chemical Engineering & Process Technology, 2013 Equilibrium moisture content-water activity data for two varieties of castor (GSS and WBS) at temperatures 30, 40, 50, 60 and 70°C and water activity range of 0.07-0.98 were determined using the static gravimetric method. A nonlinear regression programme was used to fit four sorption isotherm models (modified Halsey, modified Henderson, modified Oswin ...
