<p>The plender has a motor driving a working tool (6) that is in a form of an Archimedes screw with a thread. The thread helically extends around a central hub (60) coupled by its upper end to a solid drive integrated in rotation with the motor. A protecting cover (5) has a peripheral wall (52) covering half of the periphery of the working tool to define a mixing volume closed around the working tool when the protecting cover is applied against a base of a container.</p> |
