Soybean oil refining is a critical stage in edible oil processing, directly affecting the oil’s color, flavor, and safety. Incomplete refining not only reduces product quality but may also decrease the overall value of the oil.
Common Issues and Solutions:
1️⃣ Incomplete Degumming: During cooking, the oil foams easily at high temperatures, and heating at 280°C produces flocculent impurities.
Solution: Strictly control degumming time and temperature to ensure complete removal of impurities.
2️⃣ Insufficient Deacidification and Decolorization: Results in a high acid value and dull oil color.
Solution: Use continuous, fully sealed negative-pressure decolorization and deodorization equipment to precisely control temperature and processing time.
3️⃣ Incomplete Deodorization: Causes residual odors from bleaching earth and loss of fatty acids due to high-temperature treatment.
Solution: Apply energy-efficient refining equipment with heat recovery systems to reduce energy consumption while maintaining the oil’s natural quality.
