Resumo(s)
In the present work a diffusion based model was adopted to represent the drying behaviour of pears in a continuous
convective drier, taking into consideration the variation of the properties of the pears along drying.
The program developed simulated a significant number of situations resultant from the variation of some of the oper-
ating conditions. The temperatures tested were 30, 40 and 50 C, the air velocities were 0.5, 1.0 and 1.5 m/s, and the relative
humidity of the drying air was 40%, 50% and 60%.
From the situations analyzed, and considering the specifications required for the final product, it was concluded that the
drying should be carried out at 40 C, with a drying air velocity of 1.5 m/s and containing 60% RH.
