摘要

Thin layer air-drying experiments on passion fruit seeds were conducted and the effects of temperature and air-drying speed were investigated in a pilot air-dryer. Drying characteristics of passion fruit seeds were examined by heated ambient air at 40 and 60 degrees C and air-flow speed at 0.4 and 0.6 m s(-1). Analysis of variance showed that the main effects were statistically significant for temperature (p < 5%) and for the interaction between air-speed and temperature (p < 5%). Diffusivity coefficient dependence with temperature was described by an Arrhenius-type equation. Diffusivity coefficient rates were 1.19 x 10(-10) m(2) s(-1), at 0.9 m s(-1) and 40 degrees C, to 1.55 x 10(-10) m(2) s(-1) at 0.6 m s(-1) and 60 degrees C. Activation energies were 13.3 and 14.2 kJ mol(-1) for speeds 0.6 and 0.9 m s(-1), respectively.
