Oil extrusion process

A process for extracting oil from oil bearing materials selected from the group consisting of oil bearing seeds and plant materials, the process comprising the steps of:

• extracting crude oil from first oil bearing materials;
• introducing the crude oil into a screw extruder;
• introducing second oil bearing materials into the screw extruder;
• masticating the second oil bearing materials in the screw extruder;
• adding water to the oil bearing materials to form a slurry;
• introducing a reagent A to the slurry;
• and
• subsequently extracting resultant physically refinable product oil.

A process for extracting oil from oil-bearing materials, the process comprising:

• extracting crude oil from first oil bearing materials;
• providing second oil bearing materials;
• adding water and the crude oil to the second oil bearing materials to form a slurry;
• adding a first reagent to the slurry to form a resultant mixture;
• grinding the resultant mixture;
• heating the resultant mixture;
• subjecting the mixture to solid-liquid separation;
• subsequently extracting a physically refinable resultant oil.

A process for extracting oil from vegetable oil bearing seeds, the process comprising the steps of:

• adding feed comprising vegetable oil bearing seeds to a screw extruder at an inlet of the screw extruder;
• adding a carrier crude vegetable oil from an extraneous source to the inlet of the screw extruder;
• moving the feed and carrier crude vegetable oil from the inlet of the screw extruder to a discharge of the screw extruder;
• masticating the feed as it moves through the screw extruder;
• increasing the temperature of the feed as it moves from the inlet to the discharge of the extruder;
• discharging the feed from the extruder;
• and
• subsequently preparing a slurry.

A process for extracting oil from oil bearing materials selected from the group consisting of oil-bearing seeds and plant materials, comprising the steps of:

• introducing oil-bearing materials into a screw extruder;
• adding a carrier oil from an extraneous source to the oil bearing materials;
• adjusting the moisture content in the oil bearing materials;
• introducing reagent A into the barrel of the screw extruder;
• mixing reagent A with the oil bearing materials in the screw extruder;
• masticating the oil bearing materials in the barrel of the screw extruder;
• chemically reacting the oil bearing materials in the extruder to reduce a phospholipid content thereof;
• and,
• subsequently subjecting the oil bearing materials to a conventional extraction process to extract a resultant oil from the oil bearing materials.

A process for producing physically refinable oil low in impurities other than phospholipids from vegetable oil bearing material, comprising the steps of:

• adding at least one reagent to reduce the phospholipid content in the vegetable oil extracted from the oil bearing material to form a mixture;
• adding oil different than the oil to be produced to the oil bearing material to form a slurry;
• heating the slurry;
• sparging the slurry with steam or water vapor to remove volatile impurities from the slurry;
• and
• subsequently, producing a physically refinable oil that is low in volatile impurities.
