The purpose of solvent extraction is to remove most of the oil contained in a seed. Extraction is conducted on prepared seeds or, generally in the case of high oil content seeds, the cakes yielded by the pre-presses. A desolventiser-toaster consists of a vertical stack of several cylindrical gas-tight pans, each having a steam-heated bottom.

Solvent extraction refers to preferential dissolution of oil by contacting oilseeds with a liquid solvent. This is the most efficient technique to recover oil from oilseeds.
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.
The ground seed or cake is then purged or washed with a petroleum distillate (the most common chemical used is hexane) which releases the oil in the seed. The solvent is then “flashed off” by heating the oil in a sealed chamber.
A simplified, energy efficient process for regulating the composition of recycle solvent obtained by the phase separation of the extract of oilseed extraction with an isopropanol-based solvent. In the extraction of oilseeds with such a solvent, there is obtained, by cooling of the extract, a solvent-rich liquid phase.
The solvent extraction plant is part of vegetable oil processing plant which is designed to extract oil directly from oil seed containing less than 20% oil like soyabean fter flaking or it extracts oils from prepressed or fully pressed cake of seeds containing more than 20% oil like sunflower, peanuts, cotton seed, palm kernel, canola, copra, castor and variety of other materials.

The extraction process is the same for all eight types of oilseeds subject to this rule (soybean, cottonseed, canola, corn germ, sunflower, safflower, peanuts, and flax). In each case, the seeds are crushed and mixed with the solvent.
The flaking machine is generally used in the oilseeds pretreatment workshop to change the physical form of oilseeds, so to meet the requirements of oil solvent extraction production for oilseeds.
Today, solvent extraction using hexanes is the method of choice for large-scale oil extraction from oilseeds. However, agriculture is becoming an increasingly competitive enterprise on a global basis, dictating the need to add value close to the crop production point for sur-.

Oils from seeds or the cake remaining from expelling is extracted with solvents and the oil is recovered after distilling off the solvent under vacuum. Most small enterprises will find that small expellers are the best technology choice.
Solvent extraction is described, starting with theories behind solvent extraction, various solvents used, early equipment, and state‐of‐the‐art modern extractors. Also discussed are solvent recovery from miscella, marc, and the air and water effluents from the extraction system.
However, oil extraction by solvents turns out to be less economical than mechanical separation since the desolventizing and distillation processes to separate the solvent from the meal and the oil to recirculate the solvent is an energy (steam)-consuming process. This is true for extraction of approximately 66% up to 75% of the oil in the seed.

A much lower volume or secondary use for soybean oil and rapeseed oil, gaining popularity in recent years, is as a feedstock for biodiesel fuels for diesel engines. There are many other products such as oleochemicals made from oilseeds – and often these are provided with a solvent extraction system as a part of the total supply process.
A complete oil processing line (oil plant) generally includes expeller process and solvent extraction process. You are welcome to send us an email for more details of our oil plant. Mechanical pressing process(screw-press) expeller is the key equipment of screw-press process, which is also known as screw oil press.
In addition to hexane, the ft29 unit can employ a variety of alcohols, dilute acids, and water as the extraction solvent. The northern crops institute provides oilseed extraction services for oilseed breeders, processors, and distributors throughout the oilseed supply chain.
The solvent (hexane) enters the extractor in the opposite side of the oilseed, it is sprayed on the seed belt, flows through the same and is recovered in the underneath hopper from where it is pumped into the next sprayer step; the number of sprayer steps changes depending on the capacity of the plant.
Solvent extraction, also called liquid-liquid extraction (lle) and partitioning, is a method to separate compounds based on their relative solubilities in two different immiscible liquids.
Solvent extraction – by far the most widely used extraction process in the world for common oil seeds is solvent extraction using hexane.

Extraction is a process of separating a liquid from a solid system with the use of a solvent. Extraction is also a process of diffusion with the help of low boiling point solvent. This process gives a higher recovery of oil and a drier cake than expression. Solvent extraction is capable of removing nearly all of the available oil from oilseed meal.
Two values, peroxide value (pv) and free fatty acid (ffa), were determined for oils that had been extracted at different temperatures. Extraction of oil from oilseeds: accelerated solvent extraction.
Oilseeds and oilseed meals are included in diets fed to livestock to provide protein and energy. Oilseeds cottonseed, soybeans, and sunflower seed provide higher energy concentrations from oil in addition to protein. Some of the more commonly used oilseed meals include canola meal, cottonseed meal, peanut meal, soybean meal, and sunflower meal.
Oilseed extraction continuous solvent extraction is the most efficient method for producing high-quality vegetable oil and meal from a wide variety of oilseeds. As such, it has become almost universal in the modern oilseed industry.
Solvent extraction is used to separate oil from seeds/beans where the principle is to employ a volatile liquid in which the oil is freely soluble. The pre-processed seeds/beans are treated in a multistage counter-current process with solvent until the remaining oil content is reduced to the lowest.
