Solid Liquid Extraction

The Solid Liquid Extraction allows a soluble component of a solid mixture to be extractedwith a revolving extractor. In continuous 3-stage mode, pure solvent isdelivered from a tank to the sprinkler of the first extraction stage where itis distributed over the solid mixture. The extraction material and thesolvent move in counter flow. The extraction residue drops into a tank afterone revolution of the extractor. Valves can be used to switch to 1- or 2-stagecontinuous mode. After passing through the last stage, the extract collected in theextract tank. The extraction material is continuously fed into the cells of therotating extractor by a spiral conveyor. The solvent seeps through the extractionmaterial, absorbs its soluble components and passes into the collectingsegments. From there, the enriched solvent is delivered to the sprinkler of thenext stage. Discontinuous mode is possible with the extractor stopped.
