Oil machine for cottonseeds oil refining

NEED cottonseeds oil refining machine ?

Cottonseeds oil refining is according to the different usage and requirements, utilizing the physical methods and chemical

processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.

The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction,

will be pumped into crude oil refinery to produce cooking oil at various grades.

These processes include neutralization (removing free fatty acid), degumming, decolorization (bleaching),

deodorization.

1.Characteristics of cottonseeds oil refining

This units belongs to intermittent refining oil equipment, has all functions

of large, small scale intermittent refining equipment, and better than them.

This equipment can produce high-cooking oil or salad oil.

This units complete set combined, self-prepare heat source, gas source, electrics control. Light weight, save electricity , convenient use, this machine do not need special basis,

either indoor or outdoor is OK, just need to make up power source, water, prepare coal, alkali, P-acid, active clay, edible salt and other consume materials.

2.Main refining process of cottonseeds oil refining

(1).P-acid degumming operation of cottonseeds oil refining

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 cottonseeds oil refining

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 cottonseeds oil refining

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 fir-

st time washing, better to use thin salt water evenly spray into oil.

(4).De-watering of cottonseeds oil refining

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 rin-

se 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 cottonseeds oil refining

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 degr-

ee 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 pre-

ss filter, filter away waste clay, the last use air compressor blow clean and dry

(6).De-odor operation of cottonseeds oil refining

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, re-

lease de-odor oil , the de-odor process has finished.

Until now, the product oil after de-odor is high cooking oil, there are some

factories carrying again one time fine filtering after de-odor to increase the o-il qulity.

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.

By-Products from cottonseeds oil refining

You can get soapstock, oil foot and spent bleaching earth from oil refining process. Soapstock is the source material for laundry soap with soap making machinery and washing detergent.
