Oil solvent extraction can be used for various grain seeds, including sunflower seed, soybean/soya bean, peanut, cotton seed, corn germ, rice bran and etc.Oil extraction plant mainly includes Rotocel extractor, Loop type extractor, and Towline extractor.
● High temperature vacuum deodorization
● Reduce direct steam consumption
● Reduce deodorization time
● Reduce the hydrolysis loss of oil and prevent oxidation
● Solvent-- Extractor--Mixed oil -- 1st and 2nd evaporation -- Stripping tower -- Crude oil
● Extraction:The solvent enters material, and extracts oil inside the material under a certain level of temperature and pressure.
● DTDC:It consists of seven layers. In the first three layers, the wet mash is heated by indirect steam. In the next two layers, stripping is carried out under the action of direct steam, the sixth layer is dried with hot air, and the seventh layer is cooled.
● Evaporation:The difference between the boiling point of oil and the solvent is used to separate the solvent and the oil.
● Stripper:The separated solvent can be dissolved in the selected paraffin or solvent and recycled.
