Features:
1.Filtration and decontamination:removing the small amount of impurities from crude oil.
2.Degumming by hydration: adjusting initial temperature of crude oil is 70 °C, adding 3.5 times hot water in the phospholipid content of oil, stirring quickly (60-70r/min) 0.5h or so, phospholipid particles began to gathering when heated up to 80 °C, standing 3-8h and then Isolating lecithin oil feet.
3.Dewatering and exsolution: absolute hydration vacuum dehydration at 90-95 °C, and then vacuum precipitation: temperature above 140 °C. The operating pressure is no more than 8kPa, Using direct steam distillation for 2.5-3h, to make the residual solvent in the 50mg/kg below, secondary. rapeseed oil is produced in this way.
