ABSTRACT:
A beverage processing apparatus consisting of an outer housing having an upper portion and a lower portion which together form a closed processing vessel for containing a beverage mixture, the upper portion containing a driving motor that drives the shaft which has on it one or more processing blades, the invention being characterized by the fact that the blade or blades are pivotally attached to the shaft so as to be capable of folding up against the shaft as it is introduced into a mixture to be processed containing, for example, ice cubes, and thereafter under the influence of centrifugal force to take up a position substantially at right angles to the shaft to effect efficient processing. It is preferred that the or each blade has a surface upwardly inclined in relation to a plane at right angles to the axis of the shaft to promote folding of the blade in the event of it striking an obstacle during processing.
