Abstract
A vertical centrifugal thin film evaporator is equipped with: a cylindrical body in which an central axis of a circle is set in a vertical direction; a rotor that rotates an interior of the cylindrical body in a circumferential direction thereof; a wiper that slides on an inner circumferential surface of the cylindrical body; a fixing support that fixes the wiper and is mounted on the rotor; and a heater that heats a circumferential surface of the cylindrical body. A liquid-withdrawing structure that communicates between a space surrounded by the wiper and the fixing support and a space outside the wiper and the fixing support is formed on at least one of the wiper and the fixing support, thereby preventing a liquid to be processed from being retained between the wiper and the fixing support.
