• What is a sunflower oil press machine?
  • This is a mechanical method (An oil press machine) used for extracting oil, suitable for both large-scale and small-scale production of sunflower oil. It can be used for the initial processing of sunflower seeds to extract oil and leave behind oil cake. Sunflower oil can be pressed using either cold-pressed or hot-pressed methods.
  • What is a solvent extraction machine for sunflower oil?
  • Expeller pressed sunflower oil and solvent extraction methods are two common production processing for sunflower oil. Using the pressing method typically results in an oil residue rate of around 7%, whereas solvent extraction can reduce the oil residue rate to about 1%. It’s worth noting that solvent extraction machine is costlier.
  • How does an expeller press work?
  • An expeller press is a machine that squeezes oil through a cavity, using continuous pressure and friction. Expeller pressing extracts about 87 to 95% of the oil out of the seed, so some oil is left over after the pressing process is completed. Expeller-pressed oil is commonly refined using this same process. 2. Cold-Pressed Process
  • What are the methods of sunflower oil production?
  • In sunflower oil production industry, there are two methods commonly used. One is expeller pressing method and the other is solvent extraction. Generally speaking, on the lable of sunflower oil, if there isn’t ¡°expeller-pressed¡±, it proves that the sunflower oil is extracted by solvent extraction method.
  • What is the difference between solvent extraction and expeller pressing?
  • Generally speaking, on the lable of sunflower oil, if there isn’t ¡°expeller-pressed¡±, it proves that the sunflower oil is extracted by solvent extraction method. The expeller pressing method generally captures around 65% of the sunflower oil. Admittedly, create a lot of waste. Solvent extraction method can captures around 99% of the sunflower oil.
  • How is sunflower oil pressed?
  • Sunflower oil can be pressed using either cold-pressed or hot-pressed methods. Cold pressing sunflower oil involves oil extraction through physical mechanical means without heating, or at low temperatures (<40¡ãC). This entire process occurs at a low temperature, resulting in a lower oil yield but preserving the authentic taste of the seeds.
