carried out experiments in temperature sranging from 40 1C to 60 1C and velocities from 0.7 ms1 to 1.2ms1. The authors stated that the moisture curves followed sigmoidal shape characteristic of the drying processes and gave evidence of a reduction in drying time with the increase in temperature. They also concluded that an increase in air velocities resulted to a higher drying rate; however, the effect of the drying velocity on the drying rate was nearly negligible for lower moisture ratios.
The purpose of the present study is the experimental nvestigation of the drying kinetics of quinces for air drying
conditions (temperature 40,50and60 1C, velocity of1, 2 and 3 ms1, humidity 10%) that have not been studied in the
earlier literature and the determination of the effective moisture diffusivity as well as the activation energy for the above
conditions.
