Cooking oil mills produce corn oil. After obtaining crude corn oil, they need to refine and remove impurities to remove the crude oil itself and various impurities and odors formed during the corn germ oil production process, so as to obtain corn oil with high quality and good quality. Dewaxing is an important process that corn oil needs to undergo after refining. Dewaxing is an important link to improve the quality of corn oil, and corn oil dewaxing machine is also an indispensable equipment for producing corn oil.

The wax in corn oil mainly comes from corn germ. Therefore, high-quality corn oil needs to undergo modern dewaxing technology to maintain a clear and bright appearance and refreshing taste at room temperature and refrigeration, while ensuring that nutrients are not lost and can be stored for a longer time.

At the appropriate temperature, oil separation uses the differences in melting points and solubility of various triglycerides that constitute oil to separate oil into solid and liquid parts.

The corn germ oil dewaxing process is as follows:

Heating→heat exchange→cooling→crystallization→crystallization→filtration→dewaxed oil

1) During dewaxing, corn oil is first heat exchanged with dewaxed oil using a plate heat exchanger, and then cooled to a suitable temperature with frozen brine and put into the crystallization tank.

2) After the waxy oil is continuously cooled and crystallized to a suitable temperature, the stirring is stopped and kept for a long time to allow the uncrystallized wax to continue to crystallize and precipitate, and the small crystals to continue to grow, that is, to grow crystals.

3) The crystallized waxy oil is filtered by gravity or filter to separate the oil and wax to obtain dewaxed corn oil.
