The conventional continuous extractor uses a system of vertical batch-operated percolator columns.

The conventional continuous extractor uses an extraction system of vertical batch-operated percolator columns. The system features a layout with circular columns, which provides a more compact design. The most up-to-date processing recognizes the importance of: Optimum raw material handling and preparation, including pre/moisturing - right up to the filling of the columns Selective introduction of extraction medium at two different stages Separation of extracted solids in two extracts (split or double) Minimum residence time of extracted solids by maintaining high extract flow times
