Oil Refining

Refining Process can remove phospholipids, FFA, pigment, off-flavor and other impurities. It includes the following sections: Degumming, De-acidifying, Bleaching, Deodorizing and Dewaxing. We can supply the equipment and technology to ensure that best finished oil is achieved with the lowest production cost.
The features of Physical Refining„ÄĀChemical Refining are as follows:
‚ó Physical Refining
Physical refining means removing gum in oil during process of degumming in special method and removing FFA in process of deodorizing by steam. It has the following features:
1. Less oil loss and higher oil refining ratio;
2. No waste water in the process of production;
3. More FFA is distilled out;
4. More suitable for oil with high acid value and low gum impurity;
‚ó Chemical Refining
Chemical refining means removing FFA in a chemical way ( Acid-base neutralization). Gum and soapfoot produced is separated by centrifuges. Chemical refining has following features:
1. Excellent adaptability and less requirement to oil quality;
2. The finished oil is consistent and stable;
3. Less bleaching earth is added into compared with physical refining.
Advantages of our pre-treatment technology are as follows:
1. Complete continuous, Mechanical operation;
2. Computer automatic control system make all the pressure„ÄĀTemperature„ÄĀLiquid Level, etc controlled automatically;
3. Capacity and Quality can reach high level with the Centrifugal Separator;
4. Closed production line promise the high oil quality;
5. Energy saving with the heat multi-utilizing design;
6. High vacuum system produce high quality deodorized oil and energy saved;
