Oil Bleaching

Purifying Oils for Clarity, Stability, and Quality

Oil bleaching is a critical stage in edible oil refining that enhances the appearance, taste, and shelf life of oils. By removing pigments, oxidation products, trace metals, and residual impurities, bleaching transforms crude or neutralized oil into a clear, bright, and high-quality product. At Agroprocess Oil Tech Solutions, we deliver advanced bleaching systems designed for precision, efficiency, and consistent results—ensuring oils meet international food-grade standards for both household and industrial applications.

Key Stages in Oil Bleaching

The bleaching process involves carefully controlled steps to guarantee clarity, stability, and purity of oil before deodorization and final refining.

Neutralized Oil Conditioning

Prepares oil by maintaining the right temperature and vacuum conditions for optimal bleaching performance.

Mixing with Bleaching Earth or Carbon

Neutralized oil is mixed with bleaching earth or carbon to remove impurities, pigments, and oxidation compounds.

Adsorption of Impurities

Pigments and unwanted compounds bind to the bleaching earth, improving the oil’s clarity, oxidative stability, and overall quality.

Filtration

The treated oil is filtered to separate and remove the spent earth, resulting in a clear, light-colored, and stable oil suitable for further refining.

Moisture & Heat Control

Moisture levels and temperature are carefully adjusted to prevent re-oxidation, ensuring consistent bleaching quality and oil stability.

Quality Monitoring

Bleached oil undergoes strict testing for color, stability, and purity to confirm it meets food-grade and industrial standards.

Continuous Circulation System

Ensures uniform contact between oil and bleaching earth, enhancing impurity removal and consistent color quality.

Spent Earth Handling & Disposal

Safely collects and disposes of used bleaching earth, maintaining environmental compliance and plant hygiene.
