Fig. 4 shows the dimensionless relative humidity as a function of time for the experiments 9 (V = 10.50 m s−1, T = 40 °C and t = 2.25 h) and 10 (V = 10.50 m s−1, T = 100 °C and t = 2.25 h). At higher temperatures it was observed that the dimensionless relative humidity reached steady state more quickly than at lower temperatures, demonstrating the diffusive character of drying in these conditions. Furthermore, there was a decrease in the value of dimensionless relative humidity with the temperature increase. At higher temperature conditions the air supplied have a greater ability to withstand the evaporated water thereby there is a reduction of moisture content. This behavior is related to the fact that the thermal energy applied to the bed is proportional to the air flow multiplied by the difference between the inlet temperature and ambient temperature (Almeida et al., 2010 and Meili et al., 2010). Another expected behavior was that at higher temperatures the final moisture content of the product was inferior to those obtained at lower temperatures. In the assay 10 the final moisture content was 3.3 g/100 g (w.b.), while in the assay 9 the final moisture content was 9.10 g/100 g (w.b.). This behavior concerning the influence of temperature was observed in the other experiments.
