  • Details
  • Soybean Oil Solvent Extraction Introduction:

    Soybean oil solvent extraction plant utilizes dissolve oil solvent, through wetting and penetration, molecular diffusion and advection diffusion, extracting soybean oil from soybean embryo. The following separation of mixing oil of solvent and grease and solvent recovery processes can finally obtain crude soybean oil. The soybean cake after solvent recovery gets extracted soybean meal.

    Soybean Oil Solvent Extraction Main Section:

    Soybean oil solvent extraction. This major soya oil extraction process uses special oil extractor by reasonable method, realizing full access of solvent and embryo, so as to fully dissolve grease and obtain crude soybean oil. There are towline extractor, rotocel extractor and loop extractor selectable for soya oil extraction.

    Soybean meal desolventizing and toasting section. Wet soybean meal contains 21%-40% solvent. Desolventization and drying can finally recover solvent in soybean meal and reduce moisture. Solvent residual requires 500-1000ppm and safe moisture content. Users can choose high temperature desolventizing, low temperature desolventizing and mechanical pre-desolventizing methods.

    Mixing oil evaporation section. Utilizing characteristic of lower boiling point of solvent than soybean oil boiling point, heating boil oil and solvent mixture, allowing solvent evaporation and retain oil. Equipped with stripping method can finally remove solvent completely.

    Solvent recovery. Soybean oil solvent extraction plant uses desolventizing and mixture oil evaporation and stripping to recycle tail gas.
