• 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 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 the residual oil rate in cottonseed meal?
  • 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%. Cottonseed kernels contain 0.5%-2.5% of gossypol. After processed by the cottonseed oil refinery plant, the gossypol content in the oil is less than 0.01%.
  • What are the advantages of cottonseed oil fractionation plant?
  • Cottonseed oil fractionation plant can obtain liquid oil and solid fat by cooling crystallization and solid-liquid separation. The plant has the features of advanced technology, fully automatic, high liquid oil yield and high solid fat purity. Cottonseed oil contains a fair amount of saturated fatty acid and thus has a high melting point.
  • 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.
