year palm cooking oil refinery plant

crude cooking oil refinery plant

cooking oil refineryplant :

(1). Refining pot: used to P-acid de-gumming, alkali refining de-acid and water rinsing.

(2).De-color pot: used to remove off pigments, bleaching oils and grease de-hydrate.

(3).De-odor pot: used to remove off oils odor, foreign smells (stainless made)

Heat-transfer oil stove: supply each device production needing heat energy, temperature reach above 280 ° C.

(4).Steam generator: produce the needing steam for de-odoring and distillation.

(5).Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mmHg.

(6).Press filter: filter clay, filter out clear oil.

(7).Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.

cooking oil refineryplant Main refining process:

(1).P-acid degumming operation: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-gummingin 30 min.

(2)alkali de-acid operation: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, af-ter 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, the oil settled in the pot 6-8 hours, make oilseparate from soap.

(3)water rinse operation: 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-coloring:After dehydrate, inhale 3-5% oil weight active clay into the de-color pot to carry absorb de-coloring.

Decolor pot main axis stirring speed 60r/min, time 20 min, vacuum degree 750mmHg, is the whole absorb decolor

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.

(5).De-odor operation: 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 the direct steam under 0.1 -0.3Mpa to distillate 3-4 hours.

Shut off steam, shut off heat source, when the oil temp cooling to below 80 ° C, shut off vacuum, release de-odor oil , the de-odor process has finished.
