ABSTRACT:
A stirrer for machines for making ice cream includes a section of a rotary drive shaft, a first hub supporting a plurality of angularly equidistant radial spokes integral with the drive shaft section and a second hub supporting the same number of spokes as the first hub. The spokes of the second hub are provided at their ends with fastening components. The first hub contains radial passages that extend from a position diametrically opposite the spokes and through a longitudinal axis of the spokes to accommodate screw-type fastening members. The stirrer further includes a plurality of stirrer blades which have, at their axial ends, tapped holes for engaging the fastening members and fastening components to operatively connect the first and second hubs.
