Abstract
A centrifuge of the type including a housing and a rotatable bowl, and including a heating jacket located therebetween. The heating jacket is established through inflatable seals which selectively seal a space located between the bowl and the housing. The seals may be inflated when the bowl is stationary. A heating fluid is then introduced into the heating jacket so that collected solids in the bowl may be heated and dried. A vacuum may be applied to the bowl to assist in the removal of moisture from the solids. A scraper assembly, including at least one scraper, is disposed within the bowl. The scraper assembly pivots between a stowed position and an operative position to remove the solid that has collected on the inside wall surface of the bowl.
