i. Increasing the drying temperature or the velocity of the drying air decreases the total drying time. In particular, an
increase from 40 1C to60 1C in temperature, at 2ms1 drying velocity resulted to a decrease of the tota ltime of drying of
about 54%.On the other hand at air drying temperature of 60 1C, an increase from 1ms1 to 2ms1 in drying velocity
resulted to a decrease of the total time of drying of about 30%.
ii. At lower moisture content the effect of the air drying velocity on the drying rate is nearly insignificant.
iii. A nonlinear regression an alysis was performed, indicating that Page's thin-layer drying model is best-fitted to the
experimental results.
iv. Using the experimental data, the values of Deff were estimated, showing that an increase in drying velocity or
temperature increases effective moisture diffusivity. .
v.The estimated values of Ea and D0 lie with in the range reported in the earlier literature for quince slices drying while an
increase in drying velocity increases energy of activation.
