This study aimed to determine the viability of the of a gasifier/combustor using chip of eucalyptus firewood as fuel, in drying pulped coffee. The gasifier used was designed by SILVA (1988) [1] with modifications in the gasification chamber, being the area of the grate reduced from 0,21 to 0,06m². An addition of a coating involving the gasifier was done and a damper was placed in the exit of the combustion chamber. The air heated up in the combustor was sent to dryer developed by CAMPOS (1998) [2] that possessed four movable metallic chambers with movement and hoisted by a pulleys system. It was dried coffee with initial moisture of 54,5% w.b. up to 11,1±1,6% w.b. The moisture of the coffee was determined by equipment of the universal type, EDABO and stove. The temperature of the drying air was of 60ºC, static pressure of the air in the exit of the fan of 9mmca with speed of 46,3m³.min^-1. It was ended that the gasifier using chips of eucalyptus firewood as fuel consumed among 15,3 and 18,8 kg/hour of the biomass and that the equipment is viable for the drying of pulped coffee, not impregnating it with smoke or other particles, usually generated in the direct fired furnaces .
