Sunflower oil production process ►1. Cleaning raw materials: Different equipment is required to remove impurities, metals, etc. from raw materials. On the one hand, it is to reduce the working pressure of subsequent equipment, and on the other hand, it is to ensure the quality of oil products. The second step is cracking, but there are some shells in the raw material that are more suitable for pressing, and the shells also contain oil. ►2. Crushing and rolling: Crushing is to break the raw material into small pieces, and then use a roller to press the raw material into a flat shape, in order to improve the oil yield. ►3. Steaming and frying: Under the condition of high temperature and high steam, the raw material reaches the best state before pressing. ►4. Pressing: The heated coarse powder is continuously fed into the screw press. As the oil is squeezed through slots in the barrel, it is collected. Sunflower seeds (with shell) can contain up to 45% oil. It is rich in nutrients, and modern technology has fully mastered how to efficiently process these raw materials to obtain high-quality oil.
