Abstract

PURPOSE:To remove the sticking matter which grows by sticking to the centrifugal thin film evaporator and to enable the continuous operation over a long period of time, by fluctuating periodically the feed amount of the liquid to be treated and by fluctuating the number of revolution of the rotating blades corresponding to this value of fluctuation.
