Abstract: A centrifuge separator system includes a centrifuge bowl for receiving the feed to be separated; a flexible suspension for rotatably, flexibly supporting the bowl; and a retractable restrainer device for constraining the bowl during scraping action of a scraper blade to remove solids from the bowl. Alternatively, the bowl could be radially and rotationally constrained and the scraper rotated to remove solids from the bowl.

Abstract: An imperforate bowl centrifugal separator includes an imperforate separator bowl; a housing for rotatably mounting the bowl including a chamber in which the bowl rotates; an outlet for removing the centrate from the chamber; a discharge port in the housing for removing solids from the bowl; and a gate for closing the discharge port during extraction of centrate from the chamber and opening the discharge port to remove the solids after substantially all of the centrate has been removed from the chamber. The solids and centrate are removed from the same outlet in the bottom of the bowl.
