Abstract
Discloses is apparatus for extracting biomass from a biomass supply, including a hollow vessel in which is established a countercurrent flow of biomass in the form of liquid or particles of biomass entrained in a liquid and solvent. The vessel includes an outlet for a solvent/extract mixture at a first vessel side and an outlet for biomass at a second vessel side. The solvent/extract mixture outlet is coupled to a closed loop circuit that includes at least a separator which encompasses a condenser having first and second stages connected in series with the second of such stages operating at a lower temperature than the first stage and both stages supplying substantially uncontaminated solvent to the hollow vessel.
