Main Refining Process of Cottonseed Oil Refining Machine:
(1).P-acid degumming operation of Cottonseed Oil Refining Machine

mperature 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 of cotton Cottonseed Oil Refining Machine
After finish de-gumming process, at once add into lye carrying alkali refini-
ng de-acid, lye concentration 16 ° Be ′, super alkali is 0.1-0.3% oil weight, afterfinish 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 th-
at 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 of cottonseed oil refining machine
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 first time washing, better to use thin salt water...
