Fig. 3: Extractor For the extraction of the press cake or oil cake, a mixture of n-hexane and oil is used and the concentration of oil in hexane decreases with every extraction step. At the end of the process, before the meal leaves the extractor it will be washed with pure solvent.
The oil yield increased with increasing the extraction temperature and with decreasing the seeds-to-solvent ratio. n-Hexane was somewhat more efficient in the oil extraction than petroleum ether.
Optimization of hempseed oil extraction by n-hexane

The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solvent has lead to several
Solvent Extraction American Oil Chemists' Society
As the solvent (usually hexane) passes down through the bed of oil-bearing material, the oil is dissolved in the solvent and carried away. When properly carried out with stages of extraction (as will be described), the extraction process results in a very good separation of the edible oil from the solids or nutritious meal fraction.
Hexane Solvent Extraction Solvent extraction is a method for processing materials using a solvent to separate the various components within the oil. It is most commonly used with liquids but can also be used for gases and solids. In this method, a solvent (typically Hexane) is introduced to the material and separates its components.
