Abstract
An extractor can be used to extract solvent-soluble molecules, such as aqueous or organic-soluble molecules, from solid material feedstock for downstream processing and recovery. In one configuration, the extractor is a percolation extractor having one or more extraction chambers each containing a screen supporting the solid materials as it is conveyed through the chamber, a fluid supply system delivering extraction fluid disposed above the solid material, and a fluid recovery system disposed below the solid materials for receiving the extraction fluid and solvent-soluble molecules contained therein. The extractor further includes a screen washing system disposed under the screen and supported against movement. The screen washing system includes a washing fluid intake and a plurality of outlet nozzles directed upward towards the screen. The screen washing system can keep the screen from plugging during operation, improving the extraction efficiency of the extractor.
