ABSTRACT:
An evaporator for increasing the solids content of a liquid-solids mixture employs vapor compressor means to recycle superheated vapors that are boiled off the mixture by a heat transfer fluid. The superheated vapors are forced into the mixture before the mixture is heated by passage over a heat transfer surface, and the vapors cause the mixture to flow past such heat transfer surface at sufficient velocity to prevent excessive solids from depositing on the heat transfer surface.
