A movement device, in particular for fluid or pasty products, comprising: a helical element (2), arranged with a helical development about a longitudinal axis (x) thereof and being predisposed to rotate concentrically externally of a cooling element (100) in such a way as to push a fluid product in advancement along the longitudinal axis (x); a first connecting element (3), predisposed to reciprocally connect and maintain the turns of the helical element (2) distant from one another; a hub (4), predisposed to enable connecting the helical element (2) to a rotating element (110) predisposed to activate the helical element (2) in rotation about the longitudinal axis (x) thereof; scraper means (5, 7, 8, 9) predisposed to drag contactingly on an external surface of the cooling element (100) such as to remove accumulations and/or residues of material from the external surface. |
