Introduction to Oil Extractor

Oil extractor is the main equipment in the edible oil solvent extraction process. The pretreated oilseeds or pre-pressed oil cake are sent to the edible oil extractor by the conveyor, after solvent extraction, miscella and the wet meal is obtained. Crude extracted oil shall be refined to be edible.
edible oil solvent extraction processOil extraction technology can be classified into the batch extraction and continuous extraction in terms of operation mode; immersion extraction, percolation extraction, and combined extraction in terms of contact mode; direct extraction, pre-pressing extraction, and expansion extraction in terms of production technology.

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

1. Residue oil rate of extracting meal can be controlled under 1%, high oil yield.
2. 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.
3. Easy to realize large scale and automatic production, low labor intensity, low power consumption, low processing cost.
4. Good work environment: closed production, no leakage, no dust, low production temperature.
