Key Process Of Diacylglycerol Production Line


1.Oil Pretreatment

A diacylglycerol production line begins with raw oil pretreatment, where moisture, phospholipids, metal ions, and suspended impurities are removed to stabilize feedstock quality. The oil is degummed, filtered, and conditioned to reduce catalyst deactivation and undesired side reactions during esterification. With cleaner input oil, the diacylglycerol production line achieves higher reaction efficiency, improved DAG yield, and smoother downstream separation performance.

2.Esterification

Esterification is the key reaction step in a diacylglycerol production line. Under controlled temperature and catalyst conditions, triglycerides are converted into diacylglycerol through a selective breakdown process. By optimizing water removal and residence time, the diacylglycerol production line raises conversion efficiency, boosts DAG yield, and strengthens overall production economics.

3.Purification

Through neutralization, bleaching, and adsorption management, the diacylglycerol production line reduces free fatty acids, pigments and trace metal ions, making the reaction system more uniform and oxygen-stable. It improves color value and lowers peroxide formation. Ocean’s diacylglycerol production line produces cleaner intermediate oil with lower impurity stress and better flavor quality.

4.Molecular Distillation

To achieve commercial-grade quality, the diacylglycerol production line employs molecular distillation to separate DAG from unreacted oil, mono-glycerides, and trace triglycerides. Short-path evaporation minimizes thermal degradation while maintaining natural flavor and stability. This step is essential for obtaining high-purity diacylglycerol suitable for food-grade or nutraceutical applications.

5.Winterization & Filtration

Through winterization and fine filtration, the diacylglycerol production line cools the oil to precipitate waxes and saturated fractions before precision removal. It improves low-temperature fluidity, enhances clarity, and stabilizes storage performance. Ocean’s diacylglycerol production line ensures that DAG oil maintains a desirable appearance and consumer-grade quality even during long-term distribution.
