Ideal for high-volume extractions such as vegetable proteins, wood chips or other products that drain well, the Crown Model III Percolation Extractor is a continuous-loop, counter-current, shallow-bed extractor that’s extremely reliable and forgiving—even under adverse conditions.

Using solvent to dissolve oil or other extracts from the prepared material, the Crown Model III’s continuous-loop design is the most efficient method for extracting components from a wide variety of materials. The unique shallow, wide and long flake bed promotes excellent solvent contact, percolation and rapid drainage, allowing more complete extraction for the widest possible range of products. The Model III has even been used as a reactor with co-current and counter-current washes in the same extractor.
