Resumo: This study aimed to evaluate the energetic efficiency in coffee drying (Coffee Arabica L.) with different combinations of revolving time in a fixed-bed coffee dryer. The experiment was conducted in July 2004 in Jesuítas – Paraná state/Brazil. The dryer featured a mechanic system with rotating blades to revolve of the product at different intervals. The drying air temperature was 75°C ± 5°C. The ventilation and drying was kept constant during the tests. It was observed that the average energy efficiency was 12.3 MJ kg-1 and there was no significant difference between the treatments. For the adopted dryer model, the revolving system is recommended with three-hour intervals and continuous drying.

O experimento foi realizado no mês de julho de 2004, no município de Jesuítas – Estado do Paraná. O secador, dotado de um sistema mecânico com pás, promovia o revolvimento rotatório do produto a diferentes intervalos de tempo. A temperatura do ar de secagem foi de 75 ± 5°C. A ventilação e a secagem mantiveram-se contínuas no teste. Observou-se que a eficiência energética média foi de 12,3 MJ kg-1, não sendo verificadas diferenças significativas entre os tratamentos. Para o modelo de secador utilizado recomenda-se a utilização do sistema de revolvimento com intervalos de 3h e secagem contínua.Universidade Estadual de Maringá2010-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/367010.4025/actasciagron.v32i4.3670Acta Scientiarum.
