Abstract: There is provided a multi-module counterflow drying apparatus (100) for drying material, the apparatus (100) comprising: a material inlet (102); a material outlet (104); a heat inlet (108) for inputting heat to the apparatus such that the heat traverses the apparatus in the opposite direction than the material; and a plurality of mutually interchangeable modules (110) stacked on top of each other, wherein the material is configured to move in the apparatus from one module to another such that the movement direction of the material in a given module is opposite to the movement direction of the material in a module above or below, wherein each module (110) comprises: movable paddles (210) configured to discontinuously move the material forward in the module (110).
