Extract liquid production system and extract liquid production method

摘要

The present invention reduces the consumed amount of heat exchange medium used for heat exchange. An extract production system 10 is provided with: an extraction unit 14 for using a solvent that flows into the interior to extract an extract from a raw material, a first heat exchange unit 34 for using a heat exchange medium S to exchange heat with the solvent flowing into the extraction unit 14; and a second heat exchange unit 36 for reusing the heat exchange medium S that has undergone heat exchange at the first heat exchange unit 34 to exchange heat with the solvent that has undergone heat exchange at the first heat exchange unit 34.
