<P>PROBLEM TO BE SOLVED: To provide a concentration system including a novel centrifugal thin film vacuum evaporator capable of carrying out heating at a temperature of not higher than 40°C in particular, and of stably supplying its heating member with steam even if heat transfer from steam present in the heating member to an object to be treated is not carried out, and a method of operating the same. <P>SOLUTION: The concentration system, which includes a centrifugal thin film vacuum evaporator 1, constructed in such a manner that a liquid raw material L0 supplied onto a raw material supply face 31a receives heat from an evaporation plate 31 in the process of moving along the evaporation plate 31 to allow volatile components to evaporate and to concentrate and subsequently the concentrated liquid L1 is discharged outside via a pairing tube 6, is characterized by including a draining means disposed between a heating member 40 and a vacuum pump P3 that reduces the pressure in the heating member 40 to discharge water condensate D resulting from steam S supplied into the heating member 40, to outside. <P>COPYRIGHT: (C)2012,JPO&INPIT |
