Abstract

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.
