Physical Refining
Working Principal: It’s a kind of distillation. The FFA is removed by vapour in vacuum condition when the vapour distilled.
Features:1The techonology is simple
2) Low consumption of raw & additive material with higher output.
3) Avoiding the oil saponification with high refining efficiency and can keep the final oil more stable.
4)Can get high quality FFA without polluted water arisen.
Ways: There’re two way. They’re bath & continous
Working Condition: The equipment is same as deodor section.. Normally, it’s finished with the deodor section? at the same time at same equipment under the compeletly vacuum condition. The overplus pressure must be 0.27-0.40KPα，operation temperature is
