Abstract
A device is disclosed for downward flow evaporation of a liquid substance and subsequent condensation of the vapor formed, which includes a plurality of vertical evaporator tubes housed in a common casing in side-by-side relationship, a distributor tank which is arranged above the evaporator tubes and from which the substance contained therein can be fed to the evaporator tubes with production of a film of the substance running down the tube surface of the evaporator tubes, a heat exchanger arrangement arranged in the casing and having a plurality of vertical condensation tubes having a surface upon which the vapor can be condensed, receiving trays housed below the evaporator tubes and below the condensation tubes in the casing to separately receive unevaporated concentrate of the substance which runs down the tube surface of the evaporator tubes or condensed distillate of the substance which runs down the tube surface of the condensation tubes.
