Abstract

The objective of this work is to contribute to the valorization of Hura crepitans by kinetics study of drying at drying oven and microwawe oven of Hura crepitans seeds. The seeds were dehydrated until obtaining a constant mass, respectively in a drying oven and a microwawe oven. Drying was carried out at temperatures of 50, 60 and 70°C and powers of 140, 280 and 420 W respectively with the drying oven and the microwawe oven. The results show that, the samples kiln-dried with microphone-of (140 W and 280 W) present a phase at constant pace, which is not the case for drying with the drying oven. The rise in the temperature to the drying oven from 50 to 70°C and in the power of heating to the microwaves of 140 to 420W varies the coefficient of diffusion of 7.12×10-9m2.s-1 with 8.76×10-9m2.s-1 and of 5.03×10-8m2.s-1 with 8.64×10-8m2.s-1.The energy of seed activation of Hura crepitans is about 9.53 kJ.mol-1.
