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..
