摘要：A drier for drying wet material includes a drying chamber with a plurality ofheating region regions and a plurality of drying regions, alternatively located along thepath of the material through the drier. Each of the heating regions is heated with heating

fluid by a heating recirculation system wherein the heating fluid overall flows generallyconcurrently with the material in the chamber, but wherein the heating fluid can flow invarious ways within each heating region. A fluid circulation system flows drying fluidthrough each of the drying regions generally in countercurrent flow relative to the flowof material through the drier, although the drying fluid can flow in various ways withineach drying region. The drying fluid exiting the drier is used to preheat the heating fluidexiting the drier prior to the heating fluid reentering the drier. Makeup heat is suppliedto the system.
