混合油(也称溶剂油)精炼工艺简介:混合油与定量碱液一起进入离心混合器,经高速混合后进入反应罐延时反应,出反应罐后进入离心机进行油皂分离。分离出的重相皂脚由皂脚泵送入脱溶器,轻相的油送入第二蒸发器进行蒸发脱溶。

    混合油精炼较之常规碱炼,其优越性在于中性油的皂化机率低,油皂分离效果好(即皂脚夹油少、精炼油残皂量低),油的色泽浅,特别适合棉籽油的加工。此工艺在浸出车间可直接生产高质量的国标三级油。

    Miscella refining process: Miscella and quantitative alkali solution mixed by centrifugal mixer are transported into reactionary pot. After the reaction, the mixture is divided into two parts of light phase that is transported into the desolventizer and heavy phase that is transported into the second evaporator.

    Compared with routine alkali neutralization,its advantages are little loss of oil good separation effect and light color. Especially, it is suitable for processing of cotton seed oil. The oil is machined directly by the processing.
