In conclusion, the equilibrium moisture content (EMC) value was dependent on the ambient temperatures and the predicted EMC value from the Oswin and Halsey models were the best fitting to the experiment results of small and large shrimp, respectively. The empirical thin-layer drying equation of shrimp using Page’s model was the best fitting to the experimental results. The drying kinetics of shrimps was well explained by a diffusion model while an effective diffusion coefficient can be found using an Arrhenius function of drying air temperature. The value was in the range of 1.056×10-7 to 1.7989×10-7 m2/s at inlet drying temperatures of 40 - 70 °C. Considering the properties of dried shrimp after drying, the results showed that an infrared heat source improved the redness value of the shrimps while hot air convection gave a high brightness value compared to all other experiments. However, Hunter L-a-b values are significantly affected by drying temperature compared to the initial moisture content of the shrimps. Two-stage drying for small and large size shrimp with infrared radiation of 500 W and a drying temperature of 70 °C was found to be suitable for producing high quality dried shrimp
