The apparatus serves for the continuous mixing and suspending of material to be extracted, particularly seed material, such as soy material, with solvent or extractant, particularly hexane and other suitable hydrocarbons, provision being made for preventing the influence of atmospheric oxygen on the extraction material as well as the formation of solvent vapors throughout the entire plant. The apparatus comprises a vessel having an upper cylindrical portion and a lower funnel-shaped portion, a centrically arranged inner tube having a flared portion within said vessel and a cylindrical enlarged portion above said vessel, a chute for the feeding in of extraction material opening into said enlarged portion, a disc-type agitator carried by a shaft, an inner screen, an inlet connection piece for extractant in the region of said screen, tangentially directed dislodging scrapers, overflow connection structure, pressure-equalizing connection structure, connection structure for removing air by suction and a suspendedly mounted driving system for the shaft of the disc agitator, which system serves at the same time as a weighing element.
