Solvent extraction is a method for separating a substance from one or more others by using a solvent. The purpose of rice bran oil solvent extraction plant is extract oil from the cake. This extraction method is for larger capacity.
Rice bran oil solvent extraction plant introduction:
Solvent extraction is a method for separating a substance from one or more others by using a solvent. The purpose of rice bran oil solvent extraction plant is extract oil from the cake. This rice bran oil solvent extraction method is for larger capacity ,but the invest is a little big.
Rice bran oil solvent extraction plant adopt the selected organic solvents can dissolve the oil, after soaking and spraying, can extract the oil from seed or oil cake with high efficient. some oil seeds like rapeseed, peanut, cotton seed, sesame etc can pre-pressing first, then extraction.

Main parts of rice bran oil solvent extraction plant:
(1)Solvent pumps: continuously spray solvent to the rotary-type extractor
(2).Rotocel 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: used 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 water, 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.
