Numerical simulation of a cabinet-type superheated steam drying system was conducted and validated experimentally using shrimp as the test material. The experimental and simulated drying temperatures used were in the range of 140-160°C while the volume flow rate of steam of 1.04 m 3 /s was used throughout. The initial masses of the drying product were 50.7 and 31.2kg, with initial moisture contents of 4.0 kg/kg and 3.61 kg/kg dry basis, respectively; the final moisture content of the dried product was 0.25 kg/kg dry basis. The simulated moisture content of shrimp, the drying medium temperature at the outlet of the dryer, and the performance of the dryer in terms of drying time, drying rate, specific energy consumption, and drying efficiency, were verified using available experimental data. The results showed that the simulated results agreed well with the experimental results. Based on the present study, the desirable operating conditions were also evaluated for the dryer for shrimp by considering the optimized performance and good product quality. |
