Oil Seeds Extraction

Our Experience in Oil Seeds Extraction

Lurgi started building solvent extraction plant since the early 1940’s with the 1st generation extraction process and design patented in 1957.
In Europe, Lurgi’s solvent extraction technology is mainly used for oilseeds like rapeseed, sunflower seed and cottonseed. In Asia, extracting oil from soybean, palm kernel and rice bran are the most popular applications for our solvent extraction plant.

JJ-Lurgi has successfully delivered many milestone projects including a 5000TPD soybean extraction plant and 1100TPD palm kernel extraction plant, the biggest capacity in the SEA region.

Our Experience in Oil Seeds Extraction

Seed Preparation

The seeds have to be properly prepared to ensure that the oil cells are ruptured for the solvent to displace the oil and maximize the extraction rate of the solvent in the extractor.

  • Cleaning / Weighing
  • Conditioning
  • Crushing
  • Dehulling
  • Pre-pressing
  • Flaking
  • Expanding
  • Stabilising

Oil Extraction

Hexane is sprayed onto the product bed and is subjected to a specific retention time for optimal soaking to maximise oil extraction.

  • Solvent Extraction
  • Desolventising-Toasting-Drying-Cooling (DTDC)
  • Miscella Distillation
  • Solvent Recovery
  • Oil Drying / Degumming
  • Lecithin Drying

Solvent Recovery,
Miscella Distillation,
Meal Desolventising

Hexane will be recovered from the Miscella via a distillation process under vacuum condition. The crude seed oil free from hexane will be send to storage. The de-oiled meal leaving the extractor, which contain certain amount of hexane shall be fed to the DTDC for desolventising, toasting, drying and cooling before meal handling.
