The basic method on fraction Palm fatty acid in Crude palm oil by getting distillated
Matter this be different with processing Alkaline so where free fatty acid and Gum the oil the alkaline reaction fraction gasiform.
In and out line Refining divisible become 2 phase the are:
- Process Bleaching
- Process Deodorizer
The phase Bleaching is process disappearance gum aldehydes, ketones,pigment,tocoperol and absortivecleacn by use of essence adsorden,eg:
Bleaching Earth whereas the phase Deodorizer comprise process disappearance odor and splitting up compound carotene the thermally.
In a word the phase process Bleaching explicable as follow:

In a word the phase process Bleaching explicable as follow:
- Process Bleaching section
Heating temperature CPO up to 95-115ºC before next to injection phosphoric acid
- after injection or additional phosphoric aciddoses 0.040-0.050% with retention time until homogen
- Before oil go to Bleacher tank the additional Bleaching earth the function for corded gum hank the segmentary.
- Percentage usage Bleaching earth at accord with quality CPO
- Kefektifan Bleaching reaction fathomable decrease in color BPO (Bleach Palm Oil)
- Pigment primary cause of color is (Clorophyl and Compound Carotene)
- Process Deodorizer
- After phase Bleaching process advanced stage of phase Deodorizer the bleaching oil free of gas (Dearasi) in condition under pressure Vacuum with oil heating until 255-260°C in the instrument ampere meter external before go to deodorizer.Pressure vacuum deodorizer as need 2.0-2.5 torr or 2-3 mmHg.
