ABSTRACT:
Process of degreasing and washing objects, particularly industrially manufactured pieces having blind holes, comprises the steps of arranging a centrifuge drum in upright position, rotating the drum at high speed about its vertical axis of rotation, placing the objects to be treated into the drum and degreasing the objects. The drum is thereafter tilted into an inclined position and driven at a reduced speed so that the objects are tumbling in the drum while a cleaning and rinsing agent is charged into the drum. A higher speed is then imparted to the drum and a part of the cleaning agent is removed therefrom. The drum is thereafter returned to its vertical position where the objects contained in the drum are dried by rotating the drum at high speed while blowing hot air therein.
