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, electrics control. Light weight, 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, P-acid, active clay, edible salt and other consume materials.
2.Main refining process
(1).P-acid degumming operation
Drawing the filtered or settled crude oil into the neutral pot, control oil temperature 40 ° 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 weight.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 refining de-acid, lye concentration 16 ° Be ′, super alkali is 0.1-0.3% 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, 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 ° 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/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...
