Zusammenfassung:	HIGH EFFICIENCY COLUMN CRYSTALLIZER ABSTRACT An improved countercurrent solid-liquid contacting apparatus, and more particularly an improved counter-current crystallizer column is disclosed. The present invention embraces the discovery that column efficiency and product purity can be substantially enhanced by reducing axial liquid back-mixing by using stationary solid beds and transport means at spaced intervals along the column length.
