Thin-Layer Drying Kinetics of Pseudapocryptes Elongatus Fish in a Convective Dryer

Abstract

The present work determines the thin-layer drying kinetics of Pseudapocryptes Elongatus fish in a convective dryer. The experiments were conducted in the range of 0.5-1.5 m s^-1 air velocity, 50-70^oC drying temperature, fish size with 45 fish/kg, and 140 ± 5 mm fish length. The drying process reduces the moisture content of fish from 3.237 to 0.11 (d.b). Results indicated that the best model describing the drying behaviour of Pseudapocryptes Elongatus fish was the Two-term model with the correlation coefficient R² > 0.99976. The E_a and the D_eff of fish were 42-46.16 kJ mol^-1 and 1.621 x 10^-10 - 5.618 x 10^-10 m² s^-1, respectively. The present work is helpful in designing and operating the drying process of Pseudapocryptes Elongatus fish in the convective dryer.
