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. For multistage distillation, the feed tube of the vacuum chamber of higher vacuum stage is connected with the residue outlet tube of the vacuum chamber of lower vacuum stage for the successive collection of fractions, or it is connected with the distillate outlet tube of the vacuum chamber of lower vacuum stage for redistillation in such way that it forms a liquid seal between the lower vacuum stage and the higher vacuum stage.
