An ultrasound crystallization device includes a tubular crystallization reactor () for conducting process fluid containing substance to be crystallized, an ultrasound source () for radiating ultrasound to the tubular crystallization reactor, and a temperature-control structure () for controlling the temperature of the process fluid with the aid of temperature-control fluid. The tubular crystallization reactor is shaped to conduct the process fluid to flow around the ultrasound source, and the temperature-control structure comprises a flow-guide structure () for guiding at least a part of the temperature-control fluid to flow around the ultrasound source. The flow-guide structure improves the accuracy of the temperature control of the process fluid and also the ability of the temperature control to react to changes.
