Abstract (en)
[origin: WO0123079A1] A container (1) has a movable internal plunger (2) with a single relatively large central opening (21). The container is lined by a flexible plastics bag (3) which is inserted through the opening (21) to contain a liquid to be mixed. The plunger is moved up and down below the surface of the liquid to cause an accelerating radially inward flow of liquid (<i>A</i>) below the plunger. When the liquid reaches a central collision region the converging liquid creates an unrestricted axial flow (<i>B</i>) through the central region of the opening (21). Embodiments are described in which the bag (3) can roll into a peripheral recess in the plunger, and the radial flow can also be created by moving the bottom of the container relative to a fixed internal apertured wall. Mixing is extremely effective and very energy-efficient compared with mixing processes which involve forcing liquid through a restricted orifice.
