Winterization dewaxing equipment workshop

The oil contains a small amount of wax, which can increase the cloud point, reduce the transparency and digestion and absorption rate of the oil, and make the taste and palatability of the oil worse, thereby reducing the edible quality, nutritional value and industrial use value of the oil . On the other hand, wax is an important industrial raw material, which can be used to make wax paper, waterproofing agent, glossing agent and so on. Therefore, removing or extracting wax from oil can achieve the purpose of improving the quality of edible fats and comprehensive utilization of vegetable fat wax sources.

Winterization is a method of crystallization and separation, which is a process of cooling the oil to crystallize out the glycerides with a higher freezing point, thereby separating the oil and solid fat.

Winterization is to slowly stir the fat, control the cooling rate, and cool to about 4-6°C for about 24 hours to make the solid fat form larger crystals and separate and precipitate. After filtering, the oil is separated from the solid fat. After the oil is degummed, deacidified, decolorized, and deodorized, a small amount of solid fat will precipitate out in winter, which will affect the appearance.
