PROBLEM TO BE SOLVED: To provide a multistage centrifugal deoiling apparatus, which smoothes the move of workpieces housed in a tray to a deoiling tank by a centrifugal force to suppress the formation of injuries (hit marks) on the workpieces due to collision, and ensures the moving of the workpieces to a deoiling tank at a lower stage, so that uniform and effective deoiling is carried out. SOLUTION: The apparatus comprises a rotating drum 10 rotating around an axis extending vertically, the multistage deoiling tanks 15-19, which are in the rotating drum 10 and are formed by arranging funneled partitions 12, each having a conical slope 13 sloping down toward a center opening 14, vertically in tiers at every a prescribed distance in the axial direction, the trays 25-29 placed at the center of the deoiling tanks 15-19, respectively, and a supporting shaft 30, which is arranged at the center of the rotating drum 10 to be movable axially and vertically and supports the trays 25-29 arranged vertically in tiers in a rotatable manner. When the supporting shaft 30 moves up, each tray approaches the lower end 14b of the opening 14 of an upper stage deoiling tank. When the supporting shaft 30 moves down, each tray approaches the upper end 14a of the opening 14 of a lower stage deoiling tank to seal the opening 14. The trays 25-29 rotate as the rotating drum 10 rotates, moving the workpieces A housed in each tray to the inner peripheral wall side of the deoiling tank by a centrifugal force for deoiling.
