Working priciple

(1)P-acid degumming operation:
Drawing the filtered or settled crude oilinto the neutral pot, control oil temperature 40 ° C, liquidlevel cover theneutral pot volume about 80 %.Add into theneutral pot Pacid with 85% concentration, 0.1-0.2% oil weight.Start up neutral pot, make main shalf stirring at 60-70 r/min, finish de-gumming in 30 min.
Adjust the neutral pot oil temp to about 85 °C, add into hot water whose temp higher oil temp 10-15° C, the water use amount each time is 10-15% oil weight.
(2)alkali de-acid operation
After finish degumming process, at once add into lye carrying alkali refining deacid, lye concentration 16 ° Be ′, super alkali is 0.1to0.3% oil weight, after finish adding, continuous stirring 30min, when soap particles accumulated condensing, should reduce stirring speed, 30r/min avoid emulsion. After adding alkali, gradually rising temp to the end temp 65 ° C, see to that the rising temp speed should control at 1 degree per minute, not too fast. Shut off neutral pot drive part, theoil settled in the pot 6-8 hours, make oilseparate from soap.
(3)de-coloring:
Pump the oil netralized into decolorizer vessel , samely mixing to rise its temperature to 90 degrees,then mixing for 30 mins,to reduce water to 0.1% ,then put a little clay (decoloring media) 24 % of total oil ,mixing for 30 mins ,to reduce the temperature to 70 degrees, then filte the clay with oil filter,to get the oil decolorized .
