Professional manufactureer in edible oil refinery plant
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.
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, Pacid, 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
(2).De-color pot: used to remove off pigments, bleaching oils and grease de-
(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 Â° 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 Â° 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 Â° Be â², super alkali is 0.1-0.3% oil weigLD, 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 Â° 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 Â° C, add into hot water whose te-
mp higher oil temp 10-15Â° C, the water use amount each time is 10-15% oil
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.
After dehydrate, inhale 3-5% oil weigLD active clay into the de-color pot to carry
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 Â° 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
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 Â° C - 260 Â° 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 Â° 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 oil qulity.
The salad oil refining process is same to the high cooking oil refining proc ess, 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.
oil refinery equipment
Sunflower oil, sesame oil, cotton seed oil, peanut oil, rice bran oil, palm oil,
coconut oil, soybean oil, rapeseed oil, mustard seed oil, etc.
First grade oil, it is the salad oil .
Second oil, it is senior cooking oil.

Professional manufactureer in edible oil refinery plant
Small Scale Screw Pressing Machine is advanced black seed oil machine, characterized by simple design,easy to operate, high production capacity and high oil output rate. Moreover, this Professional manufactureer in edible oil refinery plant can be used for various raw materials, and depending on the oil content of particular crop you are pressing, Professional manufactureer in edible oil refinery plant will extract about 90%-95% oil of it.
A Screw consists basically of a worm assembly,a shft fitted with spirally-arranged worm sections,rather like a screw.The shaft turns horizontally in a cage consisting of barrel bars that are clamped together forming a kind of sloted tube around the shaft.In turning,the worm assembly moves the oil-seed from the feed-end to the dischage-end,expelling the oil through the slots between the bars of the of the cage.The oil-seed,as it moves along the shaft,loses oil,and its volume decreases accordingly.Small Scale Screw Pressing Machine can be used to press oil from Peanut,Coleseed ,Cottonseed,Sunflower Seed,Soya bean,cocoa nut,argan,sesame,black cumin,almond ,pomegranate seeds,Palm Kernal and other oil-seed material.
