Turn on the vacuum pump, the vacuum degree> 700mmHg. Alkali refining water washing after the first suction pot decolorization, stirring, temperature reached 90 ℃, stirring for 30 minutes, to a moisture to 0.1% or less, and then a small amount of decolorizing agent inhaler (clay, activated carbon), depending on the amount of oil to add color, generally accounting for 2-5% heavy oil, stirred for 30 minutes, cooled to 70 ℃, the use of compressed air pressure to the oil filter and oil separation were clay, get decolorization oil.

The principles of cooking oil decolorization and deodorization:
Decolorizing the oil sucked by the vacuum pump sweetening the pot, when the degree of vacuum reached 755mmHg or more, and distillation begun simultaneously deodorized Timing:
1.deodorizing time: 4 hours
2.deodorization temperature: 240 ℃ / 755mmHg 260 ℃ / 759mmHg
3.deodorization vacuum degree: 755mmHg or more
4.When the entire counting process, you must steam distillation
5. After the deodorization is completed, continue to close in a vacuum direct steam, closed thermal oil, cooling water valve open until the oil temperature dropped to about 40-80 ℃, turn off the vacuum pump valve, sampling after passing inspection, tank barrel, complete cooking oil production process.
