Abstract
A drier for particulate material including upper, intermediate, and lower regions. The material to be dried is flowed through the regions while a fluid, preferably ambient air, is counterflowed to the material through the lower and then upper regions, but not the intermediate region, such that the fluid cools and dries the material in the lower region and preheats the material in the upper region. The material is further heated by a makeup heater in the intermediate region to a preselected temperature.
