Sunflower Seed Processing, Oil Extraction & Refining
Ferro’s Sunflower Seed Processing ensures high-quality oil with minimal processing, retaining the natural flavor and nutritional benefits. Here’s an overview of the process:
Cleaning Process
- Seed Cleaner : Ferro Box Type Seed Cleaner eliminate large & fine size impurities to ensure a clean, high-quality product.
- Magnetic Separation : Seeds are passed over magnetic feeder to remove metal traces.
Decorticating
- Hull Removal : Seeds contain 20%-30% hulls, which are removed to improve oil quality and meal efficiency.
- Decorticator : The Ferro 48" Decorticator cracks seeds for hull removal, followed by a density separator and hull purifier to reduce oil loss.Cleaned linters are compressed into bales for sale.
Conditioning
Cooking & Conditioning : The meat is cooked to facilitate oil extraction, while during oil pressing, some impurities are also released with the oil, and they should be removed before the oil can be edible.

Mechanical Screw Pressing
Due to high oil content sunflower seed the oil extraction been proceed through two steps of sunflower seed oil extraction, first oil seed undergoes with mechanical screw press followed by second step solvent extraction, Under the Sunflower seed expelling section, the key equipment's FX-Expeller, crude oil filtration equipment's (FERRO special design 4 stage filtration) and FX-cake cooler plays a crucial role to maximize oil yield, ensure product quality, and improve operational efficiency.
Solvent Extraction
The solvent extraction is a method used to extract the residual oil from expeller outlet cake. It involves FX-Extractor equipment using a solvent (typically hexane) to dissolve the oil from the seed's pallets/ cake, followed by separating solvent by FX-Miscella Distillation and FX-DeSolventiser toaster to recycle hexane by making process efficient with achieving best results of minimal hexane losses.
Sunflower Refinery
The Sunflower Seed Edible Oil Refining Process involves several stages to transform crude sunflower oil into a high-quality edible oil. Here's a detailed breakdown: It involves multiple stages, including FX-Degumming (remove phospholipids by using water or acid), FX-Neutralization (remove FFA by treating with an alkali), FX-Bleaching (remove colour pigments by treating oil with activated carbon or clay), and FX-Deodorization (eliminates undesirable odors & volatile compound by oil heated under a vacuum), FX-Dewaxing (remove waxes by oil is chilled and then filtered the solidified wax & fats). Finally refined oil is further undergone through FERRO new design FX-Ultra Fine Polish filter to making ultra-pure polished oil for cooking.
