Detailed Description

Rice bran oil manufacturing machine for complete prodction line Pretreatment Process: 1.Screening:Removing the chaff and broken rice in the rice bran, in case of they will influence the oil yield and the desolvent of wet meal in the next process. 2.Magnetic separation :Clearing the iron impurity which might be in the rice brain. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect. 3.Quenching and tempering :it is the process of preheating so that to improve the temperature of the rice bran before puffing. After quenching and tempering the temperature will be controlled at 65--75 °C, and the moisture will be controlled at 10 ~12%. 4.Puffing: To make the rice bran powder to pellet , it is much more easy to solvent extract the oil out. 5.Drying:The moisture of puffed material comes from the extrusion machine is too big and the temperature is too high for direct leaching, the must be experience to process of drying and coo-ling, thus the moisture will reach 7%--9%. Solvent extraction process: First, send the rice bran meal to the roary extractor, the meal will be fully soaked in the extractor by the solvent. Thus, the oil in the rice bran will be absorbed in to the solvent. 1.Roary extractor: Spray and soak the pretreatment rice brain with solvent so that oil fats can be dissolved in solvent(form miscella). After processing, you can get wet meal and miscella (mixed oil) . 2. DTDC: It is usd to separate the solvent from the wet meal. 3. Miscella tanks:It is uesed for purifying miscella will be pumped into it. 4. 1st evaporator, 2nd evaporator: used to separate the solvent from the oil. After this process, the solvent can be removed 85%. 5. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling. 6. condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling. Refining Process: 1. Deacdification:Adding a little P-acid to react with the collioid and a certained concentration lye to neutralize the free fatty acid, after reaction , producing many nigre, then we separating the soapstock and oil. 2.Decoloring section:Using the active clay to absorb the pigments away. 3.Deodorization Section:In the condition of the high temperature and high vacuum, injecting a cert-ain amount of superheati-ng direct steam, the steam completely contact with the surface of the oil li-quid , taking the varities odors away . Dewaxing Process: The process of removal of the wax in the oil called dewaxing (also can be called winterization). It's fundamental is remove the wax in the oil by refrigerating crystal in the condition of los temper-ature. After the wax becoming crystal, then use plate type filter to separate it form the oil. Functions of main parts: 1. crystallizing and maturing tank: used to form crystal in the tank. 2. refrigerating set: used to make the temperature of oil become low, so that the wax can be crystall-ized. 3. brine tank: used to add brine in the oil to make the the crystallization point of the wax become low, thus, can save energy and time. 4. Plate type filter: used to separate the wax from oil. We can supply a complete production line . Welcome to visit our factory and running machine.
