Necessity of Dewaxing for Sunflower Oil Refinery

Oil refinery, Necessity of Dewaxing for Sunflower Oil Refinery. Sunflower oil content of wax depends greatly on quality of oil pretreatment process, the crude sunflower oil obtained from prepressing kernel with good husk-kernel separation effect, waxy content is about 300mg / kg-400mg / kg, the crude oil from leaching equipment, wax content is often higher than 1500mg / kg.

     The deodorized sunflower oil contains small amounts of wax, which is pumped into the crystallization tank within 8h when the pre-cooling is cooled from about 40 ℃ to 10 ℃, and then transferred to crystallize tank, falling down to about  6 ℃ within 12h, holding 4hs. That first take Parallax gravity filtration, and separate oil from wax by oil filter with compressed air. This method is called dewaxing or winterization, also called winterisation.
