1. A method of producing a plurality of liquid extracts from a solid raw material, comprising:
establishing a flow of a solvent through a bed of the solid raw material within an extraction pathway to produce a first liquid extract;
displacing a segment of the extraction pathway containing at least a portion of the raw material such that the segment becomes fluidically isolated from an upstream segment of the extraction pathway and a downstream segment of the extraction pathway; and
extending a solid body into the displaced segment such that the solid body compresses the portion of the raw material present within the displaced segment to produce a second liquid extract from the portion of raw material present within the displaced segment.
