The purpose of Main Processes of Manufacturing Rice Bran Oil preparation is to extract a portion of oil by mechanical pressing while providing pressing cakes for extraction plant. 10-1000tpd castor oil extraction machine/ castor oil mill machinery is a succession of several of the following processes: Bran Cleaning & Weighing, Cracking, Softening, Puffing,Flaking, Pressing, Oil Residue Extraction,Filling and Packing.The purpose of Main Processes of Manufacturing Rice Bran Oil flaking is to turn the softened rice bran into thin flakes (from 0.3 to 0.35mm) for the subsequent oil extraction through mechanical pressing. In addition, flakes thickness can be adjusted through roll pressure adjustment device. Horizontal drum softener is designed to adjust temperature and moisture of Rice Bran previous to flaking, 10-1000tpd castor oil extraction machine/ castor oil mill machinery improving oil yield greatly.
castor oil extraction machine
1. Introduction of castor oil extraction machine
a.Non-condensable gas enters the energy saver from the shell of the first evaporator. In energy saver, noncondensable gas exchanges heat with condensate from the evaporative condenser.
b.The condensate temperature discharged from energy saver is increased, and the solvent separated water from going to the solvent holding tank.
c.The high temperature makes it unnecessary to be reheated for the recycling, so as to save energy. Noncondensable gas from energy saver enters desolventizing condenser, in which a great deal of gas is condensed, and the tail gas is discharged into the final condenser.
d.The solvent gas from the extractor enters extraction condenser, and the noncondensable tail gas enters the final condenser.
e.For the free gas in final condenser, diversion box, holding tank, underground solvent library and miscella tank, cool them with low temperatured cold water to recycle most of solvent gas. The tail gas with little solvent goes to paraffin recovery process.
2. Main parts of castor oil extraction machines
(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. 
3. Main Process of castor oil extraction machine
(1) The material (for pretreatment) is sent to rotary extraction by the scraper conveyor. The material will extracted by the solvent or mix oil. After this step, we will get meal and mix oil.
(2) Meal is sent to toaster. Through the toaster, the solvent in the meal will separate from the meal. The solvent goes to condenser and is recycled to rotary extraction.
(3) After the mix oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the mix oil is separated.
(4) The mix oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can get crude oil and solvent. The solvent is sent to condenser and is recycled to rotary extraction.

Main Processes of Manufacturing Rice Bran Oil Rice Bran is a kind of high oil-containing oilseed. Generally 10-1000tpd castor oil extraction machine/ castor oil mill machinery is necessary to extract a portion of oil by mechanical pressing previous to subsequent process. Expeller with auxiliary cooker ensures material reach proper temperature and moisture. Shandong Leader Machinery Co.,ltd. Pressing cakes containing residual oil from 14% to 18% is then treated by solvent extraction while crude oil is to be filtered. Due to high content of residue in crude oil, Main Processes of Manufacturing Rice Bran Oil is necessary to separate oil residue by oil drag conveyor firstly, Shandong Leader Machinery Co.,ltd. crude oil then enters to settling tank for further separation. Collected residue is returned to pressing section while crude oil from settling tank is pumped to 10-1000tpd castor oil extraction machine/ castor oil mill machinery frame filter or leaf filter for further removing impurities.10-1000tpd castor oil extraction machine/ castor oil mill machinery is designed to cool down pre-pressing cakes with high efficiency, then cakes is conveyed to extraction plant.
