    Patent number: 4581830
    Abstract: The apparatus consists of a cylindrical drying chamber, which is provided with an upwardly conical bottom.

A stirrer is placed coaxially in the chamber, the blades of said stirrer being parallel to the conical bottom. Preferably, the blades of the stirrer are positioned at a small distance from the conical bottom. The cylindrical drying chamber and the annular distributor may have a common wall, which is provided with a heat insulating layer on the side facing the distributor.
