Physical Refining Plant
Delivering Superior Quality for High FFA Oils
Physical refining is the preferred method for oils with high free fatty acid (FFA) content, such as palm oil and rice bran oil. This process involves two critical stages: Pre-treatment & Bleaching followed by Deacidification/Deodorization. At Agroprocess Oil Tech Solutions, our advanced continuous refining systems are engineered to effectively remove impurities like phospholipids, heavy metals, and unwanted compounds before the deacidification stage. The result is an efficient distillation process for free fatty acids combined with partial or complete deodorization, ensuring superior oil quality, enhanced shelf life, and cost-effective performance.
Key Stages in Physical Refining
The physical refining process is carefully designed to achieve maximum oil purity, nutrient protection, and energy efficiency while ensuring compliance with international food safety standards.
Degumming & Pre-treatment
Removes phospholipids, trace impurities, and gums to prepare oil for further refining.
Bleaching
Uses bleaching earth or activated carbon to eliminate pigments, heavy metals, and peroxides.
Pre-heating & Dehydration
Gradual heating under vacuum to remove moisture and ensure uniform treatment.
FFA Distillation (Deacidification)
Distills and removes free fatty acids under high vacuum and controlled temperature.
Deodorization
Stripping steam passes through oil under vacuum to remove odor, off-flavors, and volatile compounds.
Heat Recovery (Oil-to-Oil Exchangers)
Transfers heat between hot and cold oil streams to optimize energy efficiency.
Fatty Acid Recovery
Captures and condenses distilled fatty acids for by-product utilization and reduced losses.
Final Polishing & Cooling
Cools and polishes refined oil, ensuring clarity, stability, and extended shelf life.
