Abstract: A dryer for plastic granules with a fan for air, with a drying chamber containing a regenerable desiccant, with a collecting duct connectable to the drying chamber for the drying air, with an air heating element in the collecting duct, with a plurality of drying containers connectable to the collecting duct, with a return duct from the drying containers to an inlet duct of the fan, with a first reversing valve, which connects in a first switching position the drying chamber with the collecting duct, and in a second switching position the drying chamber with the atmosphere, and with a second reversing valve, which connects in a first switching position the inlet duct of the fan to the return duct and in a second switching position the inlet duct to the atmosphere. One object is the reliable and synchronous reversing of the two reversing valves. Another object shall enable the coupling of further groups of drying container to one drying chamber. The two reversing valves are arranged in a common valve housing.
