Abstract
A rotatable basket extractor for use in extracting oil from oleaginous feed material is disclosed. The extractor includes a rotatable rotor that includes a plurality of baskets extending radially outward from a central shaft, and the baskets receive and transport the oleaginous feed material while a motor rotates the baskets between a feed inlet and a feed outlet. The rotor is located within a housing and positioned above a screen through which miscella that drains from the feed material passes. The miscella is collected in a trough located below the screen and is sprayed onto the feed material bed positioned within the baskets in a counter-current manner. A suction device pulls vapor down between the particles of the feed material bed to decrease the drainage time of the miscella through the feed material.
