Abstract
A fractionator includes a shaft attached to a drum which is positioned in a housing and which is rotatable about a substantially horizontal axis and has an inlet means for suspension and at least two outlets for fractions. The drum has a first end and a second end and includes at least two fluid tight walls surrounding the axis. The drum also extends in its longitudinal direction between the first end and the second end to define a fluid channel. The fluid channel extrends substantially parallel to the axis from the first end to the second end and continuously in a circumferential direction of at least 360.degree..
Claims10
A fractionator for continuously fractioning different fractions from a suspension, said fractionator comprising:
- a housing having inlet means for the suspension and outlet means for the fractions;
- a shaft;
- a drum positioned within said housing and being rotatable on said shaft about a substantially horizontal axis;
- said drum having an open inlet end and an open outlet end and including at least two fluid tight walls surrounding the axis and extending longitudinally substantially parallel thereto between said inlet end and said outlet end to define between said ends a fluid channel extending substantially parallel to said axis from said inlet end to said outlet end and continuously extending in a circumferential direction of said drum through an arc of at least 360.degree.;
- said outlet means comprising at least two outlets for fractions, said outlets positioned at different angular positions relative to said axis.
