ABSTRACT:
A system for the solid/liquid extraction of in particular vegetable raw materials, such as oilseeds and oil-yielding plants, with low-boiling solvents, such as gasoline and the like, in continuous co-current manner.
The equipment, which is also to be regarded as the actual extraction unit, is formed by the combination of a conveyor screw (1) having a screw flight pitch (3) which widens in the direction of the transport of material, and a screen-like or perforated bottom portion (4) provided at a short distance upstream of the discharge of the extracted material (6). The equipment is closed on all sides.
Several individual sets of equipment of this type are combined in the installation and interconnected by a logical circulation system for the miscella in such a way that the extraction time is shortened, the extraction yield is improved and the residual solvent content in the fully extracted material (groats) is reduced. The installation is built up in accordance with the modular principle by arranging, in particular, four extraction units (sets of equipment) in series.
