  • How to extract oil from sunflower seeds?
  • The Oil extracted from sunflower seeds either by screw press or by solvent extraction process. The Seeds will be either de hulled or whole seed extraction is taking place based on the requirement of the protein content of the De oiled Meal. Preparation of Sunflower Seed for Solvent Extraction Process:
  • What is sunflower seed oil?
  • Sunflower seed oil is the most ancient seed of North America which was cultivated during 3000 BC as per available records and it moved to Russia and from there to other countries. The most suitable temperature for the growth of sunflower seed is 20 – 27°C with abundant water.
  • What is the process of conditioned sunflower seed meat?
  • The conditioned sunflower seed meat transfer to the pre-pressing screw oil press where more than 50% of the Oil will be drained out and remaining 18% oil cake will be transferred to Solvent Extraction Plant. This is the system used to process the flakes directly in the solvent extraction process.
  • How to remove hulls from sunflower seed?
  • The Sunflower seed 20% to 27% of hulls which will be removed with the help of Crackers and aspiration separations process called dehulling. The sunflower seed passed through the dehullers will remove upto 15% to 20% of the hulls.
  • How to crack sunflower seeds?
  • The cleaned and magnetic separated sunflower seeds passed through the cracking machine which is called as seed cracker which contains two pairs of chilled cast iron rolls grooved suitable to crack sunflower seed into 4 to 8 pieces of uniform size to facilitate to remove hulls to reduce fiber in the final cake which help also increasing in protein.
  • What is sunflower seed expelled cake?
  • The Sunflower seed expelled cake is cooled to 55°C as the solvent extraction plant could not take cake above 55°C. The cooled cake will be passed through the cake sizing machine where the cake will be broken into 2 inch to 3 inch size pieces to improve the extraction rate.
