Method of rapeseed oil solvent extraction process: 1) The material will be have a pretreatment process , we need to clean the rapeseed , crush , cook , flaking , press the rapeseed . the oil residue in the cake is about 7-8 % .this method is suitable for small capacity ,not large . 2) The method is pre -press and solvent extraction method .It means we press the rapeseed first,then the oil residue left is about 12-13% in the cake .Then we send the cake to extractor to leah the oil from the cake ,which make surethe oil residue is about 1%.This method is for larger capacity ,and the invest is a little big . Main parts of rapeseed oil solvent extraction machine: (1)Solvent pumps: continuously spray solvent to the rotary-type extractor (2).Roary extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent(form miscella). After processing, you can get wet meal and miscella (mixed oil). (3). DTDC: usd to separate the solvent from the wet meal. (4). Miscella tank 1st: pump the miscella (oil with solvent) in to the miscella 1st , and then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline wter, at last the reactant precipitate, reaching the goal of purifying. (5). Miscella tank 2nd: the purified miscella will be pumped into it. (6). Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling. (7). condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.
