Abstract

An immersion extractor may have a housing that maintains a solvent pool in which solids material being processed is immersed during operation. One or more bed decks can be positioned inside of the housing to provide multiple extraction stages. In some examples, the bed decks are arranged to provide one bed deck positioned at a vertically elevated position relative to another bed deck, thereby providing a drop zone where the solids material passing through the machine drops from the vertically elevated bed deck to a lower bed deck. To increase contact between the solids material and surrounding solvent to improve extraction efficiency, the extractor may include mixing hardware that is configured to intermix the solids material with the solvent as solids material drops from the vertically elevated bed deck to the lower bed deck.
