  1. Feeding the Seeds: The process starts with feeding raw seeds into the machine. Common seeds include sunflower, sesame, and soybeans. You can adjust the amount by controlling the feeder.
  2. Pre-Pressing: Once fed, the seeds get crushed. During this stage, the hydraulic piston applies pressure. The crushing breaks the cellular structure of the seeds.
  3. Oil Flow: As the seeds are compressed, the oil begins to flow out. The hydraulic pressure helps in extracting a greater quantity of oil compared to traditional methods.
  4. Filtering: The extracted oil may contain small particles. A filtering system is often integrated to clarify the oil. This ensures that what you get is pure and ready for use.
  5. Byproducts: After extraction, the remaining seed cake is usually dry. This byproduct can be used for animal feed or other purposes.
