Thin layer drying, Mango, Moisture diffusion


This research demonstrates the thin layer drying of Nam Dok Mai mangoes by controlling the drying temperature and the air velocity. The 200 g of Mangoes were dried for the temperature of 40, 50, and 60 C, at air speed of 0.8, 1.0, 1.2 and 1.4 ms-1 until its final moisture content reach to 30 % (d.b.). Besides the effects of drying air temperature and velocity, seven different thin-layer models were fitted to the experimental data of mangoes. The Modified Henderson and Pabis model were revealed to be the best. The value of R2 of the Modified Henderson and Pabis model was 0.9978, indicating good fit and RMSE were also good 0.5879 %. Moisture diffusivity of mangoes have been determined experimentally and moisture diffusivity varied from 1.54 x 10-10 to 0.88 x 10-10 m2 s-1 and the higher temperature which the resulted in the increase value of the shrinkage.
