Some of the general objectives of immiscible liquid stirring are to refine the liquid diameter of the evacuation phase to obtain a symmetrical evacuation mass, such as the preparation of emulsion and emulsified oil; Some are to refine the liquid and expand the total area of two-color touch, so as to carry out the next purification or chemical change.

對化學變化僅有傳質速率小于化學變化速率時才有運用攪拌來加強反映過程的難題。自動混凝土攪拌機在制取乳濁液、乳化油時，是根據疏散做到罐里的兩相液體勻稱情況。評定這一攪拌實際操作的指標值便是疏散相的疏散度跟做到這一指標值的實際操作歲月。

For chemical change, it is difficult to use stirring to strengthen the reaction process only when the mass transfer rate is less than the chemical change rate. When preparing emulsion and emulsified oil by automatic concrete mixer, the two-phase liquid in the tank is symmetrical according to evacuation. The index value for evaluating the actual operation of mixing is the evacuation degree of evacuation phase and the actual operation time to achieve this index value.

在攪拌功效下開展提純、化學變化時，其總體目標是某一化學物質成份的傳送或一些化學物質間的反映。其評定指標值是傳質速度反應速率，而這時候攪拌的功效或是使液相疏散細化，擴大液相觸碰總面積，擴大傳質指數跟反應速率。

When purification and chemical change are carried out under the stirring effect, the overall goal is the transmission of a chemical component or the reflection between some chemical substances. The evaluation index value is the mass transfer rate and reaction rate. At this time, the effect of stirring may refine the liquid phase evacuation, expand the total liquid phase contact area, and expand the mass transfer index and reaction rate.

但是這時候并不一定要求全罐里都做到勻稱的疏散情況，而僅有在罐里的部分地區，比如攪拌離心葉輪的相鄰，有明顯的疏散功效，使罐里液體次序循環歷經這一地區造成傳質與反映，然后再循環流到罐里其他地區就很有可能了。因而很有可能說，使疏散相細化疏散，并在罐里導致循環流動性，這就是不互溶液體攪拌過程對攪拌的基本上要求，關鍵的便是要求攪拌有細化疏散的功效。

However, at this time, it is not necessarily required to achieve symmetrical evacuation in the whole tank, but only in some areas in the tank, such as the adjacent of the stirring centrifugal impeller, it has obvious evacuation effect, so that the liquid in the tank circulates through this area in order, resulting in mass transfer and reflection, and then circulates to other areas in the tank. Therefore, it is likely that the evacuation phase will be refined and evacuated, resulting in circulating fluidity in the tank, which is the basic requirement for mixing in the mixing process of immiscible liquid. The key is to require mixing to have the effect of refining evacuation.
