Patent attributes
A mixing member designed for assembly in an axially rotating manner inside the cylindrical bowl of a blender; the mixing member having a number of longitudinal blades extending parallel to a longitudinal reference axis of the mixing member and spaced angularly about the longitudinal axis to form a “squirrel cage” structure bounded laterally by a cylindrical reference surface coaxial with the longitudinal axis; each of the longitudinal blades has an outer lateral edge lying on the cylindrical reference surface and having at least one scraping device, which includes a scraper hinged to the body of the longitudinal blade to project from and rotate about an axis of rotation locally substantially parallel to the outer lateral edge of the longitudinal blade and/or to the longitudinal axis of the mixing member, and an elastic member which pushes a wedge-shaped transverse edge of the scraper radially onto the cylindrical inner surface of the bowl.
