Moisture desorption model for nonpareil almonds

Abstract The drying characteristics of individual almonds and almond parts (hull, shell, nut) were determined at 41·3 and 45·9°C and 38·8% relative humidity. Non-linear curve fitting was used to determine the parameter values in three moisture desorption models. The one-term exponential, the Page, and the two-term exponential models were compared. Residual mean squares and residuals plots were used as criteria for evaluating the simulation models. The two-term exponential model best met the criteria and is recommended as the thin-layer model for almonds.
