Extraction Methods: Cold Pressing One of the oldest methods, cold pressing, involves mechanically crushing the seeds to release the oil. Quality Control and Packaging Quality checks are integral at every stage, ensuring the oil meets standards for viscosity, acidity, and purity.
Step-by-Step Castor Oil Extraction Process
The process of transforming these seeds into the golden, viscous liquid involves a combination of agricultural expertise and industrial techniques. Harvesting occurs when the seed pods turn brown and begin to split open.
The cleaned seeds are then dried to reduce moisture content, which is critical to prevent spoilage and ensure efficient oil extraction. The seeds are heated slightly to improve oil flow, but temperatures are kept low to preserve the natural properties.

Proper storage maintains seed quality until processing begins. The crushed material is then pressed using a screw or hydraulic press, forcing the raw oil to separate from the solid pulp, known as the press cake.
