Rice bran will pass softening and conditioning, expansion process so as to make rice bran achieve certain moisture and shape for further process. The processed rice bran is sent to solvent extraction plant, which can make fully immerge with no. 6 solvent, and crude rice bran oil is available after extraction, desolventizing and toasting, high temperature evaporation etc.
Rice Bran Oil Extraction Machine is very important deep processing project in those of rice milling plant. Rice bran is by-product after rice milling process, which has not very high oil content of about 16% to 23%. Since the different characteristic of rice bran from those of high oil content oilseeds, rice bran oil solvent extraction is necessary during rice bran oil processing.
How does Rice Bran Oil Extraction Machine work?
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 send 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
The crude rice bran oil becomes edible oil after a series of oil refinery process. The whole rice bran oil processing plant project assures the highest quality edible rice bran oil with the lowest solvent residual, high oil yield, no environmental pollution etc.
