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.
