ABSTRACT:
The present invention relates to a vacuum distillation plant and a process for concentrating organic aqueous solutions, especially spissum extracts, using said plant. The vacuum distillation plant of the invention comprises a flash evaporator, a means for vapor concentration and a multi-stage condenser positioned down-stream of said means for vapor concentration, means for recycling at least part of the condensate from a condensation stage into the bottoms product being provided. In addition, the present invention relates to a process for concentrating organic aqueous solutions such as concentrated extracts using said plant.
