ABSTRACT:
A centrifugal drier comprises a conical bowl mounted in a housing for rotation about a vertical shaft. A circular wall concentrically surrounds the bowl and separates the housing chamber into a first compartment receiving the liquid from the rotating bowl and a second compartment receiving the separated solids therefrom. A skirt surrounds an upper part of the bowl and is affixed thereto. An annular baffle is affixed to the circular wall and extends between the wall and a lower skirt part. The circular wall, the skirt and the baffle define an annular space in communication with the first chamber. Rotation of the bowl and skirt affixed thereto causes the liquid to be forced centrifugally from the bowl into the first chamber and liquid droplets to be suspended in an air current in the annular space. A fibrous mat is disposed in this space and surrounds the skirt to trap the suspended liquid droplets and permit the liquid to run by gravity into the first chamber.
