Abstract

The present invention provides a process for the separation of materials obtained by means of high pressure extraction from an extraction agent, wherein extraction agent loaded with extracted material is passed from below into a separator comprising a head (2), a bottom (3), a runback pipe (4) and a heat exchanger (1) in the form of one or more pipes and extract recycled in a forced circulation via the head (2) and the runback pipe (4) to the bottom (3) and there either discharged and/or returned to the heat exchanger (1), the extraction agent evaporated in the heat exchanger being removed via a filter (11) on the head (2).
