The Oil Refining Machine is used for removing the impurities of oil, such as fatty acid, phosphatide, pigment. After the process of oil refining machine, the refined oil reaches the edible oil standard.The oil refining machine is suitable for refining various crude oil, vegetable oil, such as sunflower seed oil, tea seed oil, peanut oil, soybean oil, corn oil, groundnut oil and so on.

What is the refining process of oil refining machine?
1. Degumming: Removing the phosphatide by adding hot water, when phosphatide meets hot water, it will become bigger and bigger, then out of tanks.
2. Deacidification: Removing the FFA by add alkali liquor (for taking neutralization reaction).
3. Decolorization(Bleaching): Remove the pigment by adding bleaching earth( it has strong adsorption of pigment), and the remaining bleaching earth will be filtrated by leaf filter.
4. Deodorization: Remove the oxide, solid particle and volatile gas.
5. Waxiness impacts palatability of oil; winterization/dewaxing focuses on increasing palatability of oil and impoving organoleptic properties such as transparency, brightness, etc. Waxiness content of different oils varies; winterization/dewaxing is necessary to oils like corn oil, sunflower seed oil, cotton seed oil, etc.
In general, freezing crystallization is widely used in winterization/dewaxing. In another word, reduce oil temperature and crystallize waxiness at first, and separate solid waxiness from liquid oil mechanically.

Advantages of oil refining machine:
1.After refining the impurity of oil must be less than 0.2% ;
2.Recycling system save power and money ;
3.Lower oil waste.
