Solvent Extraction: Maximizing Yield For large-scale production, solvent extraction is commonly employed to maximize oil recovery. The crushed peanuts are then fed into a screw press or hydraulic press, where immense pressure separates the oil from the solid residue, known as press cake.

As peanuts move through the press, friction and pressure increase, forcing the oil out. These peanuts are meticulously cleaned to remove dirt, debris, and foreign materials.
Bleaching uses activated clay to absorb color pigments and contaminants, followed by deodorization under high heat and vacuum to strip off volatile compounds. Sorting and grading ensure uniformity in size and quality, which is vital for consistent oil extraction.

Quality Control and Packaging Throughout the manufacturing process, rigorous quality control measures are essential. Only sound, mature peanuts with low moisture content are chosen to prevent spoilage and optimize yield.
