Abstract (en)

[origin: EP0891820A2] The wind sifter, in particular, in the form of a cascade wind sifter, has an inner element (2) whose longitudinal contour is shaped in a zig-zag fashion, and an outer element (1) whose longitudinal contour substantially runs parallel to the corresponding contour of the rotationally symmetric inner element. The product path leads from top to bottom, and is shaped so that no so-called dead spaces are created.
