Spout Fluid Bed, Drying Model, Cricket


This research aimed to determine the most appropriate mathematical model for predicting the moisture ratio of cricket dried by a Spouted fluid bed dryer. The drying operations were: three levels of drying temperature (65, 75 and 85oC), two levels of spout air velocity (14 and 16 m/s), constant fluidized velocity of 12 m/s, and bed height of 10 cm. Two statistical indices which are the coefficient of determination (R2) and root mean square error (RMSE) were applied for finding the optimum model. The results showed that, the Logarithmic model could represent the drying characteristics of cricket most satisfactorily with the highest R2 values and the lowest RMSE values. The calculation of moisture diffusivity values achieved in the ranged from 7.63x10-8 to 11.4x10-8 m2/s. The activation energies were 17.98 and 18.16 kJ/mol. at spout velocity of 14 and 16 m/s, respectively.
