Methods of Extraction for Vegetable (Carrier) Oils
Methods of Extraction for Vegetable (Carrier) Oils. Cold Pressed or Cold Expeller Pressed: Cold pressed oils, also known as cold expeller pressed oils, have been mechanically pressed from the fatty portions of the botanical while ensuring that the maximum temperature (caused by friction) does not exceed 120 degrees.. Expeller Pressed: Expeller pressed oils are mechanically pressed from the
Essential oils often have different properties and uses than pressed or leached vegetable oils. Finally, macerated oils are made by infusing parts of plants in a base oil, a process called liquid–liquid extraction. Sources. Most, but not all vegetable oils are extracted from the fruits or seeds of plants.
Liquid–liquid extraction
Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

A Comprehensive Guide to Essential Oil Extraction Methods
SOLVENT EXTRACTION. This method employs food grade solvents like hexane and ethanol to isolate essential oils from plant material. It is best suited for plant materials that yield low amounts of essential oil, that are largely resinous, or that are delicate aromatics unable to withstand the pressure and distress of steam distillation.

Solvent extraction - Simple English Wikipedia, the free
Solvent extraction, also known as Liquid–liquid extraction or partitioning, is a method to separate a compound based on the solubility of its parts. This is done using two liquids that don't mix, for example water and an organic solvent. Solvent extraction is used in the processing of perfumes, vegetable oil, or biodiesel.

Long conveyors move the material in to the solvent extraction area, and another conveyor moves the meal back out while the oil is pumped out to storage tanks. All conveyors and piping systems are designed to minimize the chance of solvent liquid or vapor being transferred out of the extraction area.
