| Abstract |
Stirring device for ice-cream m anufact-uring machines having a whipping cylinder (1) with a horizontal axis and provided with means for extraction (3, 4, 5, 6) of the ice-cream at one. head side, the said stirring device comprising a peripheral stirrer (7) rotating about the axis of the whippin~ cylinder (1), characterised in that the peripher al rotatin.g stirrer consists of t-wo stirring blades (7) of helical shape which are arran~ed diametrically opJX>site one another and extend essentially over the entire length of the whipping cylinder (1) at a slight distance from the internal wall of the same. said stirrin~ blades (7) bein.g supoortEd Ion a hub (8) which is integral with the operating shaft (9), while there is ; .provided between the t-wo stirring blades (7) a plurality of scraping vanes (11) which are capable of interacting, with their radially external side, with the internal wall of the whipping cylinder (1) and which are distTibuted staggered an.gularly and longit-udinally in relatDn tD one another over the length of the whipping cylinder (1) itself. |
