N did not exhibit dependence on the previous drying process
conditions, being considered as an average constant value
(N=0.93).
Model parameters (K and N) have no physical meaning.
However, K parameter can be considered as an estimation of
the water gainrate when N values are constant, since N determines the scale of abscissa axis (t
N). Thus, it was observed
that K value increases with the rehydration temperature and
it reduces when the drying temperature is increased, indicating a greater rehydration rate in pineapple pre-dried at 45◦
C
than in pineapple dried at 75◦
C, as is shown in Table 2
