Abstract
A processing vessel (10) for a liquid includes an impeller (32) in an open-ended shroud (30) to cause circulation. The base of the vessel (10) communicates with a short duct (18) closed at its lower end, and the shroud (30) is shaped to ensure circulation into this dead-end duct (18). The duct is provided with ultrasonic modules (24) so that its contents are subjected to intense insonation. The insonation of the liquid can lead to improvements in the product of processes such as crystallization.
