Solvent extraction is a chemical oil extraction method to process oil out from vegetables, oilseeds and nuts by solvent. It is possible to achieve oil yields in excess of 95% with a solvent recovery of over 95% which in compare to 60 to 70% oil yield

extraction. Solvent extraction is the most efficient method of removing the oil from the seed. It may take place either in batch or continuous process. The solvent extraction most commonly used today is percolation with a countercurrent flow using hexane as solvent [5]. The rate of extraction depends on the thickness and area of solid phase,

The oil bearing material is fed into one end of a cylinder where a power-driven worm conveyor forces the material to the other end of the cylinder and out against resistance. The pressure exerted in the process squeezes out the oil. Solvent extraction is used to separate oil from seeds/beans.

3.2.1 Solvent extraction . The solvent extraction method is a conventional extraction method commonly applied to oilseeds with low oil content (< 20%), like soybean. This method is considered as one of the most efficient methods in vegetable oil extraction, with less residual oil

process. Deiss obtained a patent for batch solvent extraction of olive oil in 1856 (1). Small batch solvent extraction plants were installed in France and Italy, and by 1870, small batch solvent extraction facilities had spread across Europe. Larger scale solvent extraction plants were supplied by Rose, Downs, and Thompson (2)

The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h −1 to 150 t day −1). At the laboratory scale, many authors have

Many processes are used to recover oil from seeds, but the three common proce- dures are hydraulic pressing, expeller pressing, and solvent extraction. All three are used widely, frequently in combination. Hydraulic presses are made in a variety of sizes and types, of which three styles are employed on a large scale in this country.
