A cylindrical shell has a conical bottom with a central outlet therein. A hollow central shaft is rotatably and vertically supported within the center of the shell and has attached thereto at least one heat exchange element including lower and upper radial tubes. Hollow rectangular ducts extend vertically between the upper and lower radial tubes. Heat exchange fluid flows from the upper end of the shaft, radially outwardly through the lower radial tubes, upwardly through the rectangular ducts, radially inwardly through the upper radial tubes, and to the upper end of the shaft.
