cooking oil making machine

1.Characteristics cooking oil making machine

1.This units belongs to intermittent refining oil equipment, has all functions of large, small scale

intermittent refining equipment, and better than them.

2.This equipment can produce high-cooking oil or salad oil.

3.This units complete set combined, selfprepare heat source, gas source, electrics control. Light weight, save electricity , convenient use.

4.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 material

2. Units devices cooking oil making machine

(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).Vacuum pump: supply needing vacuum 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 cooking oil making machine :

(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-gummingin 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 vacuum valve, make the pot inside vacuum 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 vacuum, 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%.

Until now, the product oil after deodor is high cooking oil, there are somefactories carrying again one time fine filtering after de-odor to increase the oil qulity.

The salad oil refining process is same to the highcooking oil refining process, just hasa little higher requirements in each section, for example, during alkali refining, the super amount alkali a little much, when decoloring, the bleaching agent much, deodor time properly longer, the temp relatively higher, add one fine filtering section
