Abstract

A horizontal solid-bowl centrifuge with cleaning-in-place jet nozzles for cleaning the bowl in a manner complying with good manufacturing procedure is provided. The bowl is cleaned by a defined arrangement of the cleaning jet nozzles, as the bowl rotates at a speed insufficient to produce a centrifugal force equal to gravitational acceleration, where gravitational acceleration is equal to 1.0 g. The cleaning liquids are then removed after the bowl stops rotating at the lowest point of the bowl.
