Henan Doing Company is one of the earliest enterprises for researching rice bran oil mill plant, and design and contract to build the China first full continuous one grade rice bran oil production line.
Oil-content of rice bran is 14%-24%, it is a low oil-content oil materials. Compared with other oilseeds, it has the following characteristics: High starch content, variety of enzymes, easy to rancidity；Containing lecithin, bran wax and other colloidal substance; Small density, fine grain, high powder, many varieties. So, rice bran oil extraction process is very special, it needs pretreatment and pre-press machine, solvent extraction plant and rice bran oil refinery plant.
Rice bran extrusion process technology ,rice bran solvent extraction plant technology and one grade rice bran oil refinery plant are patent product of Henan Doing Company. Crude rice bran oil has high acid value, deep color, high content of wax and fat. But after refining, rice bran oil has high nutritional value, is healthy edible oil.
Henan Doing Company is one of the earliest enterprises for researching rice bran oil mill plant, and design and contract to build the China first full continuous one grade rice bran oil production line, rice bran expanding process technology and one grade rice bran oil refine got the national patent certification.
Pretreatment and pre-press machine of rice bran oil mill plant:
The complete rice bran pretreatment and pre-press machine includes :cleaning machine, extrusion machine ,pressing machine
Rice bran cleaning section:
Using a variety of equipment to separate the impurities of oilseeds. Main steps: Screening, Magnetic separation, Specific gravity stoner, etc.
Rice bran cleaning machine
Rice bran extrusion section:
The process technology of rice bran extrusion section can make the powder of rice bran become columnar structure of porous and good permeability, increase the density of rice bran, so that improve the seepage velocity of solvent, reduce residual oil of cake;
Rice bran oil extrusion machine
Rice bran pressing section:
Our rice bran pre-pressing plant has high oil extraction rate and stable performance; Our rice bran pre-pressing plant can extract rice bran oil from rice bran.

Oil refinery plant of rice bran oil mill plant:
Edible oil/cooking oil is our necessary good in our daily life. So more and more investors or business man find this business opportunity to start oil refinery factories. The oil refinery machinery is also more and more popular, especially rice bran oil refinery plant.
Rice bran oil is a kind of special oil. Because sunflower oil refining process includes degumming, deacidification, decolorization and deodorization. Rice bran oil also need dewaxing machinery besides refining machinery. Which can up to the national first grade cooking oil standard.
