Abstract
A commercial-scale oil-bearing material expeller press having an oil-bearing material inlet, an oil-bearing material press cake outlet and an oil outlet in a temperature-controlled barrel; said barrel housing a compression screw; said compression screw having a central shaft and a plurality of continuous or discontinuous screw flights wherein there are one or more compression zones along the direction of travel of said oil-bearing materials from said oil-bearing material inlet to said oil-bearing material outlet, wherein said central shaft increases in diameter in said direction of travel; and wherein at least said barrel is adapted to be cooled in a plurality of cooling zones.
Claims7
A commercial-scale expeller press for extracting oil from oil-bearing material;
- said expeller press comprising:
- an oil-bearing material inlet, an oil-bearing material outlet and an oil outlet;
- said expeller press having a temperature-controlled barrel;
- said barrel housing a compression screw;
- said compression screw having a central rotating shaft having a plurality of continuous or discontinuous screw flights;
- wherein there are one or more compression zones in said barrel along the direction of travel of said oil-bearing materials from said oil-bearing material inlet to said oil-bearing material outlet;
- wherein said central shaft increases in diameter in said direction of travel thereby to produce said compression zones;
- and wherein said barrel has an internal cage and internal linings and said linings and/or cage that are adapted to be cooled in a plurality of cooling zones;
- and wherein at least some of said cooling zones and said compression zones are collocated;
- wherein at least one of said cooling zones is located at the final compression zone before the oil-bearing material press cake outlet;
- and wherein said cooling zone incorporates an internally cooled choke ring.
