Rotatable mixing member (1) for batch-freezer machines (100) provided with a plurality of scraping paddles (4), which are placed on the longitudinal blades (3) of the rotatable mixing member (1), at the external lateral edge (3a) of the blades, so as to scrape the cylindrical inner surface (103i) of the processing tank (103) to remove the deposits of ice cream； each scraping paddle (4) being flag hinged to the respective longitudinal blade (3) so as to arrive in abutment against the cylindrical inner surface (103i) of the processing tank (103), and comprising: a platelike body (11) made of plastic material, which is adapted to scrape the cylindrical inner surface (103i) of the processing tank (103)； a stiffening plate (12) made of metal material, which is embedded inside the platelike body (11)； and at least a buffer pad (13) made of elastically deformable elastomeric material, which is fixed directly on the stiffening plate (12) and is shaped so as to protrude outside the platelike body (11) to rest in abutment on the longitudinal blade (3).
