A crystallizer comprising an elongate housing with a drivable shaft extending in the longitudinal direction of the housing, at least one cooling element being placed astride on the shaft, which cooling element to that end has a slotted recess, the cooling element being swept clean by a sweeping element rotating along with the shaft. The sweeping element comprises a shaft part which is mounted on the shaft so as to extend substantially radially and rotate along with the shaft and which carries a sweeping part rotatable about the axis of the shaft part, which sweeping part is provided with at least one sweeping arm but preferably carries four sweeping arms which extend radially relative to the shaft part and enclose equal angles relative to each other, the sweeping element being mounted on the shaft such that, viewed in the direction of displacement thereof, the free end of a sweeping arm is disposed in leading position with respect to the shaft part in a push-scraping position pressed against the cooling element.
