evaporator integral to the concentration of at least one liquid product, comprising at least two sections of evaporation and evaporation, comprising such a evaporator

摘要

Single-body evaporator for the concentration of at least one liquid product, consisting of a single vessel 1 containing at least two evaporation sections, characterised in that each evaporation section comprises: a) at least one heat exchange surface 4', 4'', b) a liquid product circuit 8, 4', 11; 9, 4'', 12 comprising one of the faces of the said heat exchange surface and c) a heating vapour circuit 3, 2, common to all the evaporation sections and comprising the other face of the said heat exchange surface, and in that it additionally comprises at least two circuits 4', 11, 19, 21, 24; 4'', 12, 20, 22, 25 for vapour originating from the evaporation of the liquid product, known as evaporation vapour circuits, associated respectively with the evaporation sections and means 26 for bringing to different pressures the evaporation vapour circuits associated with the said evaporation sections.
