Soybean Oil Solvent Extraction Process: Efficient Extraction and Enhanced Oil Quality

In modern soybean oil production, the solvent extraction process is the core method for extracting oil.
It uses food-grade solvents to efficiently dissolve the oil in soybeans, maximizing oil extraction while ensuring oil quality and compliance with vegetable oil production standards.

▸ Intelligent Solvent Extraction：Gradient percolation extraction in sealed isothermal environment; Multi-level gas monitoring + auto-locking for near-zero solvent leakage.

▸ Wet Meal Desolventizing：Sealed conveyance to DTDC systems; Precision solvent removal & moisture control with real-time residual monitoring.

▸ Miscella Evaporation：Triple purification → negative-pressure evaporation; Heat recovery integration + steam stripping purification.

▸ Solvent Condensing Recovery：Graded condensation → intelligent phase separation → automatic solvent reuse; Compliant wastewater treatment.

▸ Paraffin Oil Recovering：Solvent Extraction Plant paraffin countercurrent absorption; Near-zero emissions via efficient solvent regeneration.
