590763 A centrifuge separator including a mounting portion that releasably retains a centrifuge bowl in either stationary or spinning motion about two mounting points. A centrifuge bowl is spindled between the mounting points with the longitudinal spin axis of the bowl being in a substantially horizontal plane. One distil end of the bowl is inclined 0-30 degrees higher than an opposing distil end of the bowl, such that an inlet end of the bowl is vertically higher than an outlet end of the bowl. The bowl has an inlet through which raw material passes and an outlet through which a separated liquid product and/or separated solid product passes. An adjustable spring tensioner urges the centrifuge bowl towards one or both mounting points thereby maintaining a constant load against one or both mounting points.
