Bleaching Earth in Edible Oil Refining

The Bleaching Step in Refining

In edible oil production, bleaching is a critical purification step after neutralization. It removes color bodies, residual soaps and polar contaminants from the oil.

Erenkol bleaching earth is developed to deliver adsorption performance suited to refinery process conditions.

What Matters in Process

• Temperature and contact time: Extreme conditions can damage oil quality

• Dosage: Too little leaves color; too much raises cost and oil loss

• Moisture and acidity: Activation profile affects filterability

• Filtration: Cake resistance and filtration rate define plant throughput

What Erenkol Contributes

• More stable color reduction

• Cleaner filtration behavior

• Process repeatability

• Application support from the Bento Mineral Mining technical team

Practical Tip

Running lab bleaching curves before a plant changeover is the fastest way to cut losses and cost on the line.
