Working priciple

(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.
(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 .

Advantage

1 sesame seeds: before entering the press will be the seeds of coffee color is better, (observe the seed color with the hands of Pi Niekai), there are burst phenomenon, stir fry seeds to keep two small fire, the middle of the fire. The pressing temperature 140-150 C, water 1-1.2%, cake for a long strip shape.
2. Rapeseed: first with the fire fierce speculation to rapeseed hot, explosion sound so far, then switch to a small fire fried to rapeseed pinch opening was brownish red, pressing rapeseed temperature of 130 DEG C, moisture 1-1.5%, cake thick ness, a small flake, brownish red.
3. Peanut: fried seeds before, will be peanuts soaked again, seeds frying in the process, the kernel is fried to eight mature, pinched by hand, achieve benevolence, skin separation, benevolence is a pale yellow, about 130 DEG C temperature, water 1-2%, 0.7 to 1.2 mm thick cake, cake is sliver shaped wrinkles, smooth oil.
4 Cottonseed Kernel: before entering the squeeze oil to light yellow, temperature 120-130 C, water 1.5-2.5%, cake thickness 1-1.5 (south, north of the water is not a, proper control of water). 80-100 C, water 6-8%, every time the cake thickness 1.5-2mm, second times the cake thickness 0.7mm, but the two times the yield will be decreased.
5 sunflower: raw material to be selected, the raw water before the seed soaking, medium heat and stir fry seeds, the pressing temperature 120-130 degrees Celsius, water 1-2%.
6. Soybean: pressing before fry to burst edible, 120-130 degrees Celsius temperature, moisture 1.5-2.8%, cake thickness 0.7mm, dry again, but again dry cake material too coke, the protein loss is larger. Can be used to process two times dry, soybean fry six or seven mature, pressing temperature
