The feasibility of producing dried macadamia nuts by applying microwaves to assist the hot air drying process towards increasing industrial yield as compared to the conventional hot air process was investigated. The drying kinetics of the macadamia nuts processed with microwaves were also analyzed. It was found that it is perfectly possible to dry macadamia nuts by applying the energy of microwaves. The proposed method of applying microwaves during the drying process was shown to be efficient in preserving the natural quality of the macadamia nuts in comparison to the conventional drying process. 15091510Crank, J., (1975) The Mathematics of Diffusion, 414p. , Oxford: Claredon Press, 2nd EdSilva, F.A., Marsaioli Jr., A., Drying Brazil nuts using hot air assisted by microwaves, compared to conventionally dried samples (2003) Proceedings of the 9th.Int.Conference on Microwave and High Frequency Heating, pp. 341-344. , Loughborough University, U.K., Sept. 1-5Toledo Piza, P.L.B., (2000) Segunda Etapa de Secagem de noz Macadâmia, 93p. , UNESP, Botucatu, SP.
