Specialty Extraction / Washing / Leaching

From equipment to complete plants, Crown Iron Works delivers state-of-the-art extractors for a variety of industries.

At the heart of the extraction process is the counter-current and continuous extractor. Crown offers two different extraction techniques: percolation and immersion extraction. Your material will determine the extraction method. For instance, materials that are granular and sink in the solvent may work best in an immersion extractor. Leafy or flake-like materials tend to work better in a percolation extractor with top-down liquid flow.

Crown maintains a pilot plant with percolation and immersion extractors to help you decide which will work best for you.
