1.Characteristics
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. LigLD weigLD, 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. Units devices
(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 enerLD, 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.
3.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 weigLD.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 weigLD, 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 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
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 weigLD.
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 :
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:
After dehydrate, inhale 3-5% oil weigLD 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:
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.
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 salad oil refining process is same to the high-cooking 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.
