A method and apparatus for drying solid foodstuffs is disclosed. The apparatus comprises a gas premeable conveyor belt, a plurality of heaters arranged under the conveyor belt. The apparatus further comprises a plurality of coolers. A cool gas is supplied to a first heater, heated and drawn through the conveyor belt by a first fan. The gas is transported back under the conveyor belt to a second heater, and then again drawn through the conveyor belt by a second fan. Thus, the gas is led through and along the conveyor belt along a corkscrew-shaped path against the direction of supply of the foodstuffs. As the gas is heated along its path, the gastemperature is lowest at the first location where the gas is drawn through the conveyor belt, which first location is nearest the discharge of the apparatus.
