1.Characteristics 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…
An overview of the screw press is to produce oil processed into edible vegetable oil processing machine machinery. The oil can be well retained oil nutrients and original taste. People conform to the traditional diet Read more…
