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

摘要

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.

1. A movement device in combination with a cooling element, the movement device comprising:
a helical element, arranged with a helical development about a longitudinal axis thereof and said helical element being predisposed to rotate concentrically externally of a cooling element in such a way as to push a fluid product in advancement along the longitudinal axis; a first connecting element, predisposed to reciprocally connect and maintain turns of the helical element distant from one another; a hub, predisposed to enable connecting the helical element to a rotating element predisposed to activate the helical element in rotation about the longitudinal axis thereof; and scraper means for dragging contactingly on an external surface of the cooling element such as to remove accumulations and/or residues of material from the external surface, the scraper means comprising at least a first scraper edge which is predisposed to drag contactingly on a peripheral cylindrical surface of the cooling element, and a second scraper edge predisposed to drag contactingly on the peripheral cylindrical surface of the cooling element, the first scraper edge being sub-divided into a plurality of scraper edges, the second scraper edge being sub-divided into a plurality of scraper edges, said plurality of scraper edges of the first scraper edge and said plurality of scraper edges of the second scraper edge being reciprocally staggered along said longitudinal axis, the scraper means comprising a first frontal scraper, predisposed to drag contactingly on a front surface of the cooling element, the first frontal scraper comprising a scraper edge shaped in such a way as to pass very close to, but without touching, a thermometer which projects in a longitudinal direction from the front surface of the cooling element.
