ABSTRACT:
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.
