Oil mill rice bran production line

Oil mill rice bran production line

Company introduction

Xinxiang Chemical company is mainly focused on all kinds of seed oil extraction line . Our

company has established about 30 years . We have got much more experience in this field .

And On the technology ,we cooperate with our Industry .University .And we have the

professional engineer .And our workers all work with their certification .

Main fatty acid content of rice bran

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 40T/D 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

Material embryos→Extraction→Wet

meal→Evaporation→Cooling→Product meal packing

Mixed oil→Filter→Negative pressure evaporation → Crude oil

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 .
