In order to get pure and relatively high quality edible oil after pressing, the crude oil refinery will use our refining equipment to remove impurities in the oil. such as saponin,fatty acid, phosphatide, pigment. The refined oil reaches the edible oil standard while finished refining process.
Oil refining line Application:
Our refining machine is suitable for refining various of crude oil, vegetable oil, such as palm kernel oil, sunflower seed oil, tea seed oil, peanut oil, soybean oil, corn oil, groundnut oil, rapeseed oil and so on.
Oil refining line Advantage:
2.Customized crude oil refining line capacity. We customize plant as per your requirement for the capacity.
3. Flexible usage. The crude oil refining line can work independently or together with whole oil production line.
4. Two sets centrifugal machine make sure all continuous production , degumming result is very good.
5.The refined oil has high quality and is good for long time storage.
6. Oil can reach national standard(LEVEL 2), it can be sold in supermarket.
(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 .
