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.
Claims9
A processing vessel comprising walls and a base defining a container for a liquid, an impeller to cause flow of liquid in the container, a duct whose bore communicates with the liquid in the container, means for subjecting liquid in the duct to ultrasonic insonation, and the impeller being arranged to cause circulation of liquid between the duct and other parts of the container, the duct either being enclosed entirely within the container, or projecting from the container and having a dead-end remote from the container.
