Main Refining Process of Cottonseed Oil Refining Machine:
(1).P-acid degumming operation of Cottonseed Oil Refining Machine
Drawing the filtered or settled crude oil into the neutral pot, control oil te- 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 evenly spray into oil.

(4).De-watering of cotton seed oil refinery machinery
Start vacuum machine, open the vacuum valve on the de-color pot, make the pot inside vacuum above 750mmHg , inhale the clear oil after water rinse into the de-color pot.
Start up de-color pot main axis, stirring at 30r/min, and make the pot inside oil temp reach 90 - 95 ° C, carrying vacuum dry hydrate, about 30 min, no frog in the pot, indicate that the dehydrate finished.

(5).de-coloring of cotton seed oil refinery machinery
After dehydrate, inhale 3-5% oil weight active clay into the de-color pot to carry absorb de-coloring. De-color pot main axis stirring speed 60r/min, time 20 min, vacuum degree 750mmHg, is the whole absorb de-color craft process requirement. Shut off vacuum valve, open vacuum break valve, stirring non-stop, reduce the oil temp down to 70 ° C, the de-color finished.
Continuous stirring, open oil outlet valve, press the de-color oil into the press filter, filter away waste clay, the last use air compressor blow clean and dry.

(6).De-odor operation of cotton seed oil refinery machinery
Open the vacuum valve, make the pot inside vacuum degree gradually reach above 750mmHg.
Inhale the de-color oil after filter into the de-odor pot, see to that oil amount should cover the pot volume 60%.Control oil temp at 240 ° C - 260 ° C, use thedirect steam under 0.1 -0.3Mpa to distillate 3-4 hours.Shut off steam, shut off heat source, when the oil temp cooling to below80 ° C, shut off vacuum, release de-odor oil , the de-odor process has finished. Until now, the product oil after de-odor is high cooking oil, there are somefactories carrying again one time fine filtering after de-odor to increase the oil quality. The sunflower oil refining process is same to the high-sunflower oil refining process, just has a little higher requirements in each section, for example, during alkali refining, the super amount alkali a little much, when de-coloring, the bleaching agent much, de-odor time properly longer, the temp relatively higher, add one fine filtering section.

Ruggiero” Refining your solutions means making good ideas even better-that is, making the results of your creative thinking more effective, more workable, more attractive” (Ruggiero, 2009 P. 189). The three steps to follow in refining your solutions are to working out the detail, finding imperfections and complications and making problems. Original Problem The original issue that I had a problem with was the ability to learn the new 787 Dreamliner in order to complete my statement of work in an efficient amount of time. The initial solution was to pair up with someone that was more knowledgeable in that particular area or system and learn it that way. Several reasons that I was not able to learn this airplane with the time frame given were not enough time, systems were more complex than what I was used to, and also there were too many mechanics that were picked over me to get that job to actually learn it. After looking at the solution that I had decided based upon my time frame, and talking it over with some co-workers I had to rethink my solutions to the problem. Initial Solutions Initial solutions that I seem fit that will benefit my time schedule would be to learn the airplane on my spare time. Playing with the airplane while no one was working was also an option, that way I can see which systems affects each other, and also......
