What are the main steps or methods for converting corn oil into biodiesel?

The main steps include: 1) Filtering and preheating the corn oil, 2) Mixing it with methanol and a base catalyst (like NaOH), 3) Conducting transesterification to form biodiesel and glycerin, 4) Settling and separating, and 5) Washing and drying the biodiesel. The GlobeCore USB biodiesel production plant integrates all these steps, ensuring automated control of temperature, mixing, and separation for consistent, high-quality fuel output.
