Resumo: In this work, drying curves were obtained for the star fruit (Averrhoa carambola L.) in a tray dryer. From theses curves, drying rates and diffusivity data were also obtained and semi-theoretical models were adjusted. The drying curves were obtained using a tray dryer with temperatures of 50, 60 and 70°C and an air flux of 1.5 m s-1. The Page, Henderson & Pabis and Exponential models were fitted to the experimental data by non-linear regression. All fitted models presented high determination coefficients (R2). The Page model showed the best fit. It was observed that effective diffusivity, calculated by Fick’s law, increased with temperature.

A partir dessas curvas foram obtidos dados de taxa de secagem e de difusividade, além do ajuste de modelos semiteóricos aos dados experimentais. As curvas de secagem foram obtidas, utilizando-se um secador de bandejas nas temperaturas de 50, 60 e 70°C e com fluxo de ar de 1,5 m s-1. Aos dados experimentais foram ajustados os modelos de Page, Henderson e Pabis e Exponencial, utilizando-se regressão não-linear. Todos os ajustes tiveram coeficiente de determinação (R2) superior a 0,96, mas o modelo de Page foi o que apresentou melhor ajuste. Observou-se que a difusividade efetiva, calculada a partir da lei de Fick, aumentou com a elevação da temperatura.Universidade Estadual De Maringá2010-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/604810.4025/actascitechnol.v32i3.6048Acta Scientiarum.
