If you want to improve the quality of edible oil, the vegetable oil refining plant is necessary. But the decolorization section and deodorization section are the most important in the whole line.
The main content of vegetable oil is triglyceride which is colorless in the liquid state and white in solid state. But different kinds of vegetable oil have different colors, mainly because there are different pigments in oil. The purpose of decolorization is to remove these pigments.
Decolorization tower
Decolorization is an important step in the process of vegetable oil refining equipment. The quality of decolorization seriously affects the quality of oil production.
The reasons as following:
First of all, adsorbent is the most important factor affecting the quality of oil decolorization.Due to their different properties, different adsorbents have different effects on the decolorization of the same oil or different kinds of grease. Therefore, according to the difference of decolorizing oil, when decolorizing, select the adsorbent with different activities, low oil absorption rate , moderate particle size and easy filtration to improve the quality of decolorization .
Secondly, the decolorization of oil mainly use adsorption and decolorization methods.There are physical changes and chemical changes in the process of adsorption and decolorization, which are accompanied by energy exchange. Therefore, when the oil is in contact with the adsorbent, the temperature has an obvious effect on the decolorization effect.
At last, the quality of the decolorized oil is also related to water, phospholipid content, residual soap amount, metal ion and oxidation degree, which needs removing in the refining process.
