An improved longitudinal extractor utilizing a solvent for removing an entrained liquid from a carrier medium. The improved extractor includes a sprocket driven continuous chain-link conveyor mounted both in cooperation with an upper carrier medium chamber and a lower liquid collection chamber. The chain link conveyor has an upper run which moves the carrier medium past sparging solvent nozzles and a lower run which cleans the collection chamber by continuously scraping the bottom of the collection chamber free of sedimentation and hazardous build-up. The carrier medium is supported on a plurality of spaced-apart longitudinal members which allow the miscible fluid resulting from percolation removal to flow therebetween into the collection chamber. A plurality of spaced-apart collectors are arranged along the bottom of the collection chamber to provide for continuous removal of the miscible fluid from the collection chamber.
