The dewaxing section of new corn oil refining process placed between the bleaching and deodorizing steps, deodorizer removes fatty acids reduce the acid and diatomaceous earth in the soil odor removal, effective control of the quality of oil products.
Traditional corn oil refining process is adding to the oil filter aid 0.2% by mass to deodorized oil, deodorized oil temperature needs to be cooled to 20 ° C for 48 hours, with stirring, slowly waxy oil agglomeration, and finally the wax separated from the oil with a filter. The new corn germ oil refining processing line is added to the bleaching with the oil filter aid 0.2% by mass , rapidly cooled to 5-10 ℃, accompanied by slow speed stirring to 10-13r/min, under this condition, for 7 - 8 hours , and then a horizontal filter to remove the wax .
