APPARATUS AND METHOD FOR EXTRACTING BIOMASS

摘要

There is disclosed apparatus and a method for extracting biomass from a liquid biomass supply, the apparatus including a hollow vessel (11) in which is established a countercurrent flow of biomass in liquid form (or including particles of biomass entrained in a liquid) and solvent. Solvent containing extracts stripped from the biomass is processed in a closed loop circuit to separate the biomass and the solvent from one another. The solvent is re-cycled for further use in the vessel (11). Depleted biomass is stripped of solvent entrained therewith by heating and condensation. The biomass residue is then suitable for use, e.g. as an animal feed.
