Movement device, in particular for fluid and/or pasty products, including at least one scraper for removing accumulations and/or residues of material from a cooling element
A movement device, in particular for fluid or pasty products, including: 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 at least one scraper element (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.
