ABSTRACT:
A counter-current leaching or extraction tower for comminuted vegetable matter such as sugar beet cossettes, or crushed sugar cane, is provided with conveying elements, the longitudinal dimension of which may be altered in response to the operating condition in the material or matter being leached. Especially, the baffle members in the tower and, if desired, also the conveyor screw wings which are arranged to cooperate with the baffle members, are adjustable in their length in response to control signals derived from sensors, such as strain gauges, attached to the conveying elements. The angular position of the conveying elements in a plane parallel to the motion of the screw wings and relative to a radial direction may also be adjustable in response to the same type of control signals. The conveying elements may be constructed to include telescoping members which are longitudinally and thus radially extendable and retractable relative to the volume of the extraction tower. The combination of the several adjustabilities of the conveying elements provides an efficient localized control of the operating conditions throughout the tower volume.
