Cold chemical refining process

This process is very similar in principle to the standard chemical refining process except  

The remainder of the process is the same. This allows the separation of the wax and soap at the same time. The oil is also protected against the high temperature conditions used in the other methods for refining the oil. 

In this process, cold degumming can be undertaken if desired. However, the separation centrifuge requires double the capacity of the standard degumming process because the viscosity of the oil is much higher at the lower temperature.

There are two principal continuous refining processes physical refining and chemical refining. Three other continuous refining techniques used in the sunflower oil industry are improved modifications of the above processes. These include the cold chemical refining process, the modified chemical refining process and the modified physical refining process. 

The cold oil is treated with caustic in the same manner as in the standard Long-Mix chemical refining process.
