The utility model discloses an efficient evaporation ware has adopted the high effective distribution measure that a time sum of distribution secondary distributes and combines in the section that distributes to the abundant distribution of heavy raffinate at the heating section has been guaranteed, high -efficient collection measure, the effectual back mixing that prevents heavy raffinate have been adopted in the heating section export, adopted at segregation section and removed the foam structure, prevented that liquid from smuggleing secretly, in addition, equipment can have been guaranteed and can operate that the efficient evaporation ware that just uses does not relate to the drive disk assembly, for quiet equipment to the design of whole evaporimeter under the high vacuum degree to reduced from the possibility of drive disk assembly gas leakage, and then guaranteed the high vacuum degree of evaporimeter.
