Effects of the extraction conditions on the yield and
Rice bran oil was obtained from rice bran by solvent extraction using ethanol. The influence of process variables, solvent hydration (0–24% of water, on mass basis), temperature (60–90 °C), solvent-to-rice bran mass ratio (2.5:1 to 4.5:1) and stirrer speed (100–250 rpm) were analysed using the response surface methodology.

Improving the solvent-extraction process of rice bran oil
Extracting crude oil from oilseeds is the first step in the production of vegetable oil. Organic solvent-extraction is widely applied. The production of high value rice bran oil is gaining increased interest, and is the subject of the present paper. Field data from a 32 T/day pilot plant in Heilongjiang will be compared with engineering simulations. Since these processes are energy-intensive, two strategies for saving
