Setting Up A Soybean Oil Production Line
The soybean oil production line is a complete processing system designed to extract, refine, and package high-quality soybean oil from raw soybeans. This production line integrates advanced machinery and automation to ensure efficiency, high yield, and food-grade oil quality. Soybean oil is widely used in cooking, food manufacturing, biodiesel, and industrial applications due to its nutritional value and versatility.
A well-designed soybean oil production line includes several key stages: cleaning, conditioning, pressing, solvent extraction (optional), refining, and packaging. The process maximizes oil recovery while maintaining product purity and meeting international food safety standards.
Main Sections of a Complete Soybean Oil Production Line
1. Cleaning & Dehulling
Purpose: Remove impurities (dust, stones, stems) and separate soybean hulls.
Equipment: Vibrating sieve, magnetic separator, destoner, dehulling machine.
Process: Raw soybeans are cleaned, dried, and dehulled to improve oil extraction efficiency.
2. Conditioning & Flaking
Purpose: Soften soybeans for better oil release.
Equipment: Cooker/conditioner, flaking machine.
Process: Soybeans are heated (conditioned) and pressed into thin flakes to rupture oil cells.
3. Oil Extraction (Mechanical Pressing or Solvent Extraction)
Mechanical Pressing (for Small/Medium Scale)
Equipment: Screw press (expeller).
Process: Flakes are pressed to extract crude soybean oil (residual oil in cake: ~6-8%).
Solvent Extraction (for Large Scale)
Equipment: Extractor, desolventizer, distillation system.
Process: Hexane dissolves oil from flakes, which is then evaporated to recover crude oil (residual oil: <1%).
4. Crude Oil Refining
Degumming: Removes phospholipids using water or acid.
Neutralization: Reduces free fatty acids (FFA) with caustic soda.
Bleaching: Adsorbs pigments and impurities using bleaching earth.
Deodorization: Eliminates odors and volatile compounds via steam distillation.
5. Oil Packaging & Storage
Final oil is filtered, cooled, and stored in tanks or bottled for distribution.
6. Byproduct Processing (Optional)
Soybean meal (from pressing/solvent extraction) is used as high-protein animal feed.
Hulls can be processed into fiber supplements or fuel pellets.
