Abstract: Block short-way evaporator with wiped-off film for vacuum and molecular distillation which is suitable for large-scale production. The evaporator is composed of one or more vacuum chambers in which parallel vertical double-sided flat evaporators with wipers for wiping evaporating areas and double-sided flat condensers are alternately located so that they form a continuous block. On the bottom of each chamber distillate collecting troughs with distillate tubes are formed alternately below double-sided flat condensers using separating partitions, and below double-sided flat evaporators residue collecting troughs with residue outlet tubes are formed, feed tubes being led through the bottom and the double-sided flat evaporators into separating troughs in the upper part of the double-sided flat evaporators.
