ABSTRACT:
An auger is accommodated in a vertically disposed cylindrical refrigerated casing for scratching an ice layer made around the inner periphery of the refrigerated casing and feeding the scratched ice upward. The auger includes a columnar main body and a spiral blade disposed around the outer periphery of the main body. The cross section of the spiral blade in the axial direction of the main body is formed of an upper end surface extending outward in a radial direction from the main body, a lower end surface spaced axially from the upper end surface and extending outward in the radial direction from the main body, and a tapered surface linearly connecting both the extreme ends of the upper end surface and the lower end surface. The tapered surface extends upwardly and radially inwardly from a radially outermost portion of the extreme end of the lower end surface.
