APPARATUS AND METHOD FOR CONTINUOUS EXTRACTION USING NON-MISCIBLE LIQUID.

摘要

In this apparatus and this continuous extraction process, the filling material and the extracting liquid are charged respectively at the top and at the bottom of the column (11), against the current, the refined product and the extracting liquid containing the extracted substance. are discharged at the bottom and at the top of the column. To promote contact between the load and the extracting liquid, an agitator is used composed of a vertical shaft animated by an oscillating rotary movement and sieves or radial screens extending from the central shaft to near the surface. internal of the cylindrical wall of the column.
