Abstract: This study aimed to evaluate the fixed-bed coffee dryer, by means of different combinations of revolving times, using a noncontact thermometer. The experiment was developed in the month of June 2004 at a farm located in Jesuítas, Paraná State, Brazil. Coffee (Coffea arabica L.) variety IAPAR 59 was used. The dryer used was of the fixed-bed model, with metallic drying chamber, with cylindrical format, with an adapted grain revolving system. It was observed that there was a thermal reduction of 156.7oC (79.1%) in the system going from the furnace to the drying chamber. The combination that provided smaller reduction of temperature was with continuous ventilation and 40 minutes revolving interval at every 3 hours until the end of the process. The combination that provided the greatest reduction in temperature was with continuous revolving, with a reduction of 81.09% in the surface temperature of the product.
