Abstract
An apparatus for extracting biomass includes a closed loop circuit having an extraction vessel (11), an evaporator (12), a compressor (13), a condenser (14) and (optionally) a storage reservoir (15) operatively connected in series. A pumped recirculation loop (20) recirculates a portion of the output of the extraction vessel (11) for further contact with biomass. One or more modifiable resistances to flow (12;23) control the flow of solvent around the recirculation loop (20) and the main closed loop.
