Working Principal of Edible Oil Solvent Extraction
Working Principal of Edible Oil Solvent Extraction
Solvent extraction is an advanced oil manufacturing method widely used in the world. The process includes solvent extraction, miscella separation, wet
meal desolventizing and drying, solvent recovery.
Solvent extraction adopts selected organic solvent that can dissolve oil to extract oil from pretreated oilseeds or pre-pressed cake by immersion or
percolation in the oil extractor. The mixed liquor obtained is called miscella. The wet meal is discharged from the meal outlet and sent to the desolventizer
toaster to remove the solvent. The thick miscella is filtered and sent to the evaporation system. Utilizing the difference of boiling point between the
selected solvent and oil, after miscella evaporation and stripping, the solvent evaporates and separates with oil, thus the crude extracted oil is obtained.
The solvent vapor is condensed and cooled for reuse. The crude oil is sent to the refining workshop and undergoes a series of refining processes such as
degumming, de-acidification, bleaching, and deodorization to obtain the edible oil.
Advantages of Edible Oil Extraction
- Residue oil rate of extracting meal can be controlled under 1%, high oil yield.
- Good meal quality, favorable for making food or extracting vegetable protein, improving the nutritive value and practical value of feed, and increasing the efficiency of fertilizer.
- easy to realize large and automatic production, low labor intensity, low power comsumption, low processing cost. Good work environment, closed production, no dust, low production temperature.
