Latest Patents

Nongxue Qiu holds a patent for a high-efficiency supercritical oil extraction method. This method involves a unique approach where extraction is performed in three stages. In the early extraction stage, an extractant is used from top to bottom in an extraction kettle. The kettle is then flipped 180 degrees during the middle extraction stage, continuing the top-to-bottom extraction. Finally, in the later extraction stage, extraction is conducted from bottom to top using a conventional extractant. This innovative technique significantly improves extraction efficiency, shortens extraction time, and reduces the amount of extractant needed, leading to a more economical oil extraction process.
