Cottonseed Oil Refining Machine Refining Process Introduction
Main Refining Process of Cottonseed Oil Refining Machine:
(1).P-acid degumming operation of Cottonseed Oil Refining Machine
Drawing the filtered or settled crude oil into the neutral pot, control oil te- mperature 40 ° C, liquid level cover the neutral pot volume about 80 %.Add into the neutral pot P-acid with 85% …show more content…
Start vacuum machine, open the vacuum valve on the de-color pot, make the pot inside vacuum above 750mmHg , inhale the clear oil after water rinse into the de-color pot.
Start up de-color pot main axis, stirring at 30r/min, and make the pot inside oil temp reach 90 - 95 ° C, carrying vacuum dry hydrate, about 30 min, no frog in the pot, indicate that the dehydrate finished.
(5).de-coloring of cotton seed oil refinery machinery
After dehydrate, inhale 3-5% oil weight active clay into the de-color pot to carry absorb de-coloring. De-color pot main axis stirring speed 60r/min, time 20 min, vacuum degree 750mmHg, is the whole absorb de-color craft process requirement. Shut off vacuum valve, open vacuum break valve, stirring non-stop, reduce the oil temp down to 70 ° C, the de-color finished.
Continuous stirring, open oil outlet valve, press the de-color oil into the press filter, filter away waste clay, the last use air compressor blow clean and dry.
(6).De-odor operation of cotton seed oil refinery machinery
Open the vacuum valve, make the pot inside vacuum degree gradually reach above 750mmHg.
Inhale the de-color oil after filter into the de-odor pot, see to that oil amount should cover the pot volume 60%.Control oil temp at 240 ° C - 260 ° C, use thedirect steam under 0.1 -0.3Mpa to distillate 3-4 hours.Shut off steam, shut off heat source, when the oil temp cooling to below80 ° C,
