Wintone Machinery adopts the most advanced CE and ISO9001 approval continuous cottonseed oil refining process line to get high purity and high oil yield refined cottonseed oil. Available with both physical and chemical refinery technology, we are able to provide customers the most affordable cottonseed oil refining machines including design, manufacturing, installation with guaranteed quality and reliable service.

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% 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.
(2)alkali de-acid operation of cotton Cottonseed Oil Refining Machine
After finish de-gumming process, at once add into lye carrying alkali refini- ng de-acid, lye concentration 16 ° Be ′, super alkali is 0.1-0.3% oil weight, afterfinish 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 th- at the rising temp speed should control at 1 degree per minute, not too fast.
Shut off neutral pot drive part, the oil settled in the pot 6-8 hours, make oil separate from soap.
(3)Water rinse operation of cottonseed oil refining machine
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.Start neutral pot drive part, make the main shalf stirring washing at 30r/m-in, make the oil and water fully contact, stirring time 5-10 min.If oil/soap separate not ideal, the oil contains relative high left soap, the first time washing, better to use thin salt water evenly spray into oil.

(4).De-watering of cotton seed oil refinery machinery
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, shut off vacuum, release de-odor oil , the de-odor process has finished. Until now, the product oil after de-odor is high cooking oil, there are somefactories carrying again one time fine filtering after de-odor to increase the oil quality. The sunflower oil refining process is same to the high-sunflower oil refining process, just has a little higher requirements in each section, for example, during alkali refining, the super amount alkali a little much, when de-coloring, the bleaching agent much, de-odor time properly longer, the temp relatively higher, add one fine filtering section.
