Table 1 lists the estimated Page model parameters (kP and n) as
a function of the drying conditions, where kP is the Page drying rate
constant. Individually, temperature had the highest contribution
(83.2%) and air velocity had a low contribution (2.6%) on the drying
rate constant, kP. On the other hand tray rotation did not have
a significant contribution over this kP. In contrast, the effect of the
three combined variables accounted for 12.8% contribution to the
kP. These results agree with other reports in the literature; Khattab
(1997) reported that the kP constant was not only a function of
temperature, humidity and air velocity, but also of the space
coordinates which in our study were varied by means of the tray
rotation parameter.
