Dewaxing freezer

Dewaxing freezer is a commonly used mechanical equipment in oil and fat equipment.

In normal times, for example, certain oils and fats such as rice bran oil, rice oil, sunflower oil, etc., as well as a small amount of wax, will blend into the oil. When these oils cool down, they will crystallize.

The decrease in temperature is an important way to produce crystallization, which generally leads to turbidity in the product, affecting the purity of the appearance and thus affecting the use of the product.

Oil dewaxing and freezing is a process of processing oil through steps such as degumming, deacidification, decolorization, and deodorization. The oil is cooled to 1U-5U and maintained for 24 hours to allow crystallization to occur.

Further filtration is used to separate the oil and wax, and the same methods are employed for dewaxing and winterization. The ultimate temperature for cooling is different, but the latter is lower.
