An improved barrel extruder for extracting oil from seeds and other vegetable matter comprises a barrel screw that extends a substantial distance from the barrel downstream end and substantially through an extractor head. The extractor head is divided into three sections comprising a screen section and a port section where oil is extracted under extreme pressure and a tip section where the pulp is forced through a narrow gap to provide back pressure to the pulp in the port section. Under the extreme pressure developed in the port section, a substantial portion of the oil content of the oil seed or vegetable matter is extracted from the pulp. The extractor head is configured to permit the screen section and port section and separately the tip section to be easily exchanged for oil seeds and vegetable matter with different pulping characteristics and oil volume or percentage content. The tip section can be exchanged without removal of the extractor head and the other section reached by unbolting and removing the extractor head from the extended extruder screw.
A rotating screw oil extractor comprising a barrel having a hollow core and lacing any ports for release of oil, a rotatable extruder screw in the core, loading means in communication with the core and a first end on the barrel spaced downstream from the loading means, the extruder screw having a portion of the screw extending to a second downstream end spaced well beyond the first downstream end on the barrel,
The method of maximizing the extraction of vegetable oil from vegetable matter comprising crushing and mixing the vegetable matter in a barrel extruder lacking any ports for release of oil,
An extractor head attachable to a barrel extruder for the extraction of oil from vegetable matter comprising an elongate shape having a bore therethrough, said bore adapted to accept an extruder screw extending substantially therethrough to a downstream end;
