Abstract:
A counterflow oilseed extractor comprising:a) a plurality of flake receiving stations disposed along a conveyor for transporting oilseed flakes in a direction from a flake inflow port to a flake outflow port;b) a plurality of solvent inflow ports oriented to contact said oilseed flakes with a solvent; andc) a plurality of miscella outflow ports oriented to accept a miscella exiting said oilseed flakes, said solvent inflow ports and said miscella outflow ports positioned to transport solvent in a direction opposite the direction of said oilseed flakes, wherein one or more of said plurality of solvent inflow ports and two or more of said plurality of miscella outflow ports are switchable so that said extractor can extract a first oilseed flake type miscella from a first oilseed flake type and a second oilseed flake type miscella from a second oilseed flake type concurrently without substantial commingling of said first oilseed flake type miscella and said second oilseed flake type miscella.
