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 dehydrate.
(3).Deodor pot: used to remove off oils odor, foreign smells (stainless made)
Heattransfer 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).sunflower oil refining machine / soybean oil production plant made in china pump: supply needing sunflower oil refining machine / soybean oil production plant made in china for dehydrate, de-color, de-odor
(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 oilinto the neutral pot, control oil temperature 40 ° C, liquidlevel cover theneutral pot volume about 80 %.Add into theneutral pot Pacid 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.
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/min, make the oil and water fully contact, stirring time 5to10 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.
(2)alkali de-acid operation
After finish degumming process, at once add into lye carrying alkali refining deacid, lye concentration 16 ° Be ′, super alkali is 0.1to0.3% 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, theoil settled in the pot 6-8 hours, make oilseparate from soap.
(3).de-coloring:
Pump the oil netralized into decolorizer vessel , samely mixing to rise its temperature to 90 degrees,then mixing for 30 mins,to reduce water to 0.1% ,then put a little clay (decoloring media) 24 % of total oil ,mixing for 30 mins ,to reduce the temperature to 70 degrees, then filte the clay with oil filter,to get the oil decolorized .
(4).De-odor operation:
Open the sunflower oil refining machine / soybean oil production plant made in china valve, make the pot inside sunflower oil refining machine / soybean oil production plant made in china degree gradually reach above 750mmHg.
Inhale the decolor oil after filter into the deodor pot, see to that oil amount should coverthe pot volume 60% Control oil temp at 240 ° C to 260 ° C, use thedirectsteam under 0.1 to0.3Mpa to distillate 3-4 hours.
Shut off steam, shut off heat source, when the oil temp cooling to below 80 ° C, shut off sunflower oil refining machine / soybean oil production plant made in china, release de-odor oil , the de-odor process has finished.
(5).De-Waxing operation
Lower temperature for rid off the wax for better quality oil,which adopt two steps. The basic process: heating oil to 70 degrees for melting the wax into liquid ,then cool it slowly to 25 degrees and keep it for 24to48 hrs; the cooling speed is 1 degrees/h better,then filter it with crystal plate filter to get the clear oil and most of wax ,then clear oil go into the second Crystal vessel ,the operating method is the same as first .the wax of oil would be controlled to under 0.03%.

FAQ
Q: How to ask quotation?
A: Please note us what tpye of raw seeds , and how many tons of raw seeds you want to treat per day, then we will send you quotation as soon as we can.
Q: What's the difference between sunflower oil process and soybean oil process?
A: The biggest difference between these two is that the sunflower oil need dewaxing after refining.
Q: Why need extraction ?
A:If only pressed, oil residue inside cake is very high at lease 6%. But after extraction, the oil residue will be less than 1%, which greatly increases the oil yield.
Q: What chemical is used in oil extraction machine, and this chemical can be recovered?
A: Solvent n-hexane, most of this chemical can be recovered for recycling use.
Q: What will be happened if without good dewaxing?
A: Without good dewaxing, the final oil will be not so transparent as the oil with good dewaxing, especially in cold weather, the oil will easily become milky, or some solid inside.
Q: Do you offer oversea installation ,commissioning and training?
A: Yes. We will send experts to install, commission the plant and train workers.
