What is Edible Oil Production Line: A Complete Processing Flow Guide

1. Oilseed Pretreatment

The initial stage prepares oilseeds for efficient oil extraction through several steps:

• Cleaning to remove impurities like stones, dirt, and metal particles
• Dehulling or shelling for seeds with hard outer coverings
• Crushing to break oilseeds into smaller particles
• Cooking or conditioning to optimize oil yield through controlled heating and moisture adjustment

2. Oil Extraction

Oil is extracted using one of two primary methods:

• Mechanical Pressing - Uses multifunction oil press machines or automatic oil press machines to physically extract oil through pressure
• Solvent Extraction - Employs vegetable oil solvent extractors to chemically extract residual oil from pressed cake, achieving higher yields

3. Crude Oil Treatment

Extracted crude oil contains impurities that must be removed before refining:

• Sedimentation to separate large particles
• Filtration to remove finer impurities
• Degumming to eliminate phosphatides and胶质

4. Oil Refining

The refining process transforms crude oil into high-quality edible oil using edible oil refinery machines through:

• Deacidification to remove free fatty acids
• Bleaching to improve color and remove pigments
• Deodorization to eliminate undesirable odors and flavors
• Dewaxing for oils that require winterization
