2. Main refining process introduction about Professional refinery equipment for cooking oil refining equipment,used oil refinery equipment

 

(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-gumming

in 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, 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, the oil settled in the pot 6-8 hours, make oil separate from soap.

 

(3).Water rinse operation:

Adjust the neutral pot oil temp to about 85 ° C, add into hot water whose te-mp 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/min, 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-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 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

(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.

 

 

3. Characteristics about Professional refinery equipment for cooking oil refining equipment,used oil refinery equipment

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, elect-rics 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, Pacid, active clay, edible salt and other consume materials.

 

4. Units devices about Professional refinery equipment for cooking oil refining equipment,used oil refinery equipment

(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.
