Abstract
An apparatus for the solvent extraction of oil-bearing materials having a two-deck, loop-shaped housing is provided. The apparatus has a feed inlet for the materials and an outlet for the solvent-wet extracted materials. An assembly of two or more endless chains are connected by a series of baffle plates and driven by a set of two or more drive sprockets that transport the materials from the feed inlet to the outlet over an upper deck, along an elbow and over a lower deck the end of which serves as a draining section, both of which decks retain the materials but let miscella pass through. Inside the housing, the materials are sprayed with solvent that percolates through the materials and is collected below the decks and sprayed again onto the materials in a counter-current manner.
