Product Description
Double Decolorization Rice Bran Oil Extraction Making Machine Manufacturer
Rice Bran Oil processing machine with high yield
1,Introduction of the Rice Bran Oil processing machine
A.There are mainly three parts in the rice bran oil making process, pretreatment,
leaching (extracting) and refining.in this oil making process,the Essential oil equipments
have to used,such as extraction machine, DTDC, refining pot, degumming pot and so on.
B.After the refining of five steps , we can get the grade 1 rice bran oil,you can get different
grade oil with different equipment, the detail information we will talk in our specific
condition.
2.Introduction of making rice bran oil method:
♦press method:
cleaning and separating----steam cooking----cooking----press----filter----crude oil----refining----refined oil
(suitable for small scale rice bran oil production)
♦solvent extraction method:
cleaning----expanding----drying----extractor----mixed oil with solvent---- miscella evaporation ----steam stripping----crude oil----refining----refined oil
this method includes the four process of solvent extraction, wet meal desolventizing, miscella evaporation,solvent recovery
♦Introduction of the refining process:
Crude oil----filter----degumming----deacidification----decoloring----filter----deodoring----dewaxing----defat----first grade oil
Main fatty acid content of rice bran
Stearic acid | 1.0-3.0 % |
palmitic acid | 12-18 % |
linoleic acid | 0.5-1.8 % |
phytosterol | 3.0-4.5 % |
oleic acid | 38-52% |
oryzanol | 0.1-3.0 % |
Rice bran oil maked process
Rice bran - pretreatment - oil solvent extraction - oil refinery - packing
Rice bran production pretreatment
The pretreatment process , the rice bran need to be have a magnetic separation ,removing the small iron . Then we need to
clean the rice bran ,wipe off the middle or samll light impurities
Then exrusion puffing , make the oil come out easily .After that ,we need to make the rice bran dry ,whicn control the
moisture between 9-9.5 % . Then we send the rice bran to extractor for leaching .
The process
Rice bran→Magnetic separation→Cleaning →Extrusion Puffing →Counter-current drying→To leaching plant Rice bran Oil physical Refining
Oil solvent extraction of rice bran oil making
When we get the rice bran seed cake from pretreatment ,we need to put the cake to the extractor .Then the solvent oil
dissolve in the oil . We get the mixed oil . We heat the mixed oil by vapor . And the solvent changes gas . Then we get the
oil from the cake .
The process is like oil extracted - wet meal desolvation - mixed oil vaporation - stripping by steam - solvent recovery
Refinery of rice bran oil making process
We want to get the one grade rice bran oil or two grade rice bran oil .And we must refined the crude oil ,by degumming ,
decolorization , deodorization , deacidifiztion ,dewaxing . We wipe off the phospholipid , free fatty acid , color ,and smell ,
wax . Then the oil can be used .
The process is Crude oil - degumming - decolorization - deodorization - deacidification - dewaxing .

The main process of rice bran oil dewaxing equipment :
(1Dewax of rice bran oil dewaxing equipment :used to remove off the wax in the oil, in order to get the high quality oil.(2)Heat-transfer oil stove of rice bran oil dewaxing equipment : supply each device production needing heat energy, temperature reach above 280°C.
(3) Steam generator ofrice bran oil dewaxing equipment : produce the needing steam for de-odoring and distillation.
(4) Vacuum pumpof rice bran oil dewaxing equipment : supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.
(5) Press filter of rice bran oil dewaxing equipment : filter clay, filter out clear oil.
(6) Air compressorof rice bran oil dewaxing equipment : blow dry bleached clay, blow empty the leftover oil in the press filter.
oil dewaxing and degrease process work under slowly stirring and cool the oil to certain temperature in fixed
time (technical security),and make waxy formed bigger crystallization,then separation exhalation,after filtering ,it separates the fluid oil and solid fat .After fractionation ,the oil will be clean after 5.5 hours in 0 °C,but it also can keep the transparency and flowability in the refrigerator and improve the oil quality and appearance.
