ABSTRACT:
A centrifugal drier comprises a rotary closure member mounted in the rotary drier basket and closing off the lower part of the interior basket chamber. Purging means is mounted on the periphery of the closure member and includes an annular element coaxial with the basket and having an exterior conical surface parallel to the conical wall of the basket. The exterior surface of the annular element is at a small distance from the screen and defines an annular ejection chamber open towards the basket wall. The annular element defines an annular inlet chamber open towards the rotary axis of the basket, a narrow passage connects the inlet chamber with the ejection chamber, and at least one fixed spray nozzle delivers a purging liquid to the annular inlet chamber.
