Why is the requirement of temperature in every steps of edible oil refining process different?

Because every step of edible oil refining process has its own function, the requirement of temperature in every step of edible oil refining process is very strict. Usually, the temperature of every step is decided by engineers when designing.

Every step of edible oil refining process has different requirements of temperature

In the whole edible oil refining process, the requirement of temperature is not less than 60 degree. And all the edible oil refining process is heated by heat conductive oil. Before refining process starting, the heat conductive oil need to be increased to 85℃ firstly, and then in degumming, deacidification, decolorization and deodorization process, the crude oil will be heated into different temperature based on the requirement of refining process.

But more remarkable, using higher temperature can reduce the deodorization time. According to Doing Company engineer, in the range of deodorization temperature, increasing of every 17℃, dedorization time will reduce half. But the temperature can not be over high, or it will produce harmful substances.
