Function: Removes gum impurities (phospholipids, proteins, mucilaginous substances) from crude oil to improve quality, storage stability, and downstream processing efficiency.
Based on hydrophilicity of gums:
Hydration Degumming:
Hot water/electrolyte (NaCl, phosphoric acid) is added to heated oil (60–85°C) under agitation.
Hydratable phospholipids swell, coalesce, and settle as sludge.
Acid Degumming:
Inorganic/organic acids (phosphoric/citric acid) remove both hydratable and non-hydratable phospholipids.
Ideal for high-purity oils (e.g., physical refining).
High-Efficiency Separation: Optimized control of temperature, agitation (30–60 rpm), and water dosage (1–3%).
Multifunctional Design: Integrates degumming & deacidification in one vessel.
Automated Control: Real-time monitoring of key parameters (viscosity, pH, temperature).
Edible Oils: Soybean, rapeseed, sunflower oil refining.
Industrial Oils: Removal of gums & impurities.
| Aspect | Benefit |
|---|---|
| Oil Quality | Reduces phosphorus to ≤10 ppm; improves NSI & oxidative stability. |
| Cost Saving | Lowers chemical/energy consumption in downstream neutralization. |
| Eco-Friendly | Minimizes acid/water usage; sludge byproduct recyclable for lecithin. |
| Reliability | Robust construction (SS304/316L); CIP-enabled; maintenance-free seals. |
