  • What is cottonseed oil plant?
  • The cottonseed oil plant includes cottonseeds pretreatment and prepressing workshop, cottonseed cake solvent extraction workshop and crude cottonseed oil refinery plant. The residual oil rate in the cottonseed meal is lower than 1%. Cottonseeds contain a toxic pigment which called gossypol, of which the content is 0.15%-1.8%.
  • What is cottonseed oil extraction?
  • Oil extraction is using the organic solvent to extract oil from the pre-pressed cake inside the oil extractor. Multiple oil extractors such as loop type extractor, rotocel extractor and towline extractor can be used for the cottonseed oil extraction plant. After oil extraction, miscella and the solvent containing wet meal are obtained.
  • How much cottonseed oil is produced worldwide?
  • This statistic shows the production volume of cottonseed oil worldwide from 2012/2013 to 2022/23. Global production of cottonseed oil has been increasing in recent years, ending with 4.97 million metric tons of oil produced in 2021/2022. In 2022/2023, 5.02 million metric tons are forecast to be produced.
  • Why did cottonseed oil become a substitute for soybean oil?
  • By world war II, the shortage of cottonseed oil forced in utilizing direct substitute soybean oil. The production of soybean oil outranked the production of cottonseed oil by 1944 due to the shortage of cottonseed and the cost of soybean oil falling below than cottonseed oil.
  • How is wet meal extracted from cottonseed oil extraction plant?
  • The wet meal from the oil extractor enters the DTDC desolventizing the cottonseed oil extraction plant.After pre-desolventizing, desolventizing, drying, and cooling, the solvent is removed and the dry meal is obtained and sent to the meal storehouse for packaging.
  • What is cottonseed oil used for?
  • Cottonseed oil is mixed with alkali which reacts with free fatty acids to form soapstocks. The mixture is centrifuged to separate the soapstocks from oil. The soapstocks have strong adsorbability and can adsorb some pigment, protein, phospholipids, mucilage and other impurities.
