Peeling of the shells of boiled eggs is realized continuously, promptly and simply by introducing the boiled eggs into a cylinder through which water is flowing, the cylinder performing circular movememt about a substantially horizontal axis with the magnitude of the circular movement increasing gradually from an initial portion towards a terminal end portion. The boiled eggs are firstly made to collide with the inner surface of the cylinder by small circular movement of the cylinder, and rendered more elastic with the eggshells of fine fragments to the degree that the shell membrane remains unbroken. Next, the shell membrane is broken by applying a whirling water stream and a centrifugal force generated by large circular motion. The boiled egg contents are then separated from the eggshells so smoothly as to be slipped out of their shells.
