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. 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.

在制取乳浊液、乳化油时，是根据疏散做到罐里的两相液体匀称情况。评定这一搅拌实际操作的指标值便是疏散相的疏散度跟做到这一指标值的实际操作岁月。

When preparing emulsion and emulsified oil, the two-phase liquid in the tank is symmetrical according to the 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.

在搅拌功效下开展提纯、化学变化时，其总体目标是某一化学物质成份的传送或一些化学物质间的反映。其评定指标值是传质速度反应速率，而这时候混凝土搅拌机搅拌的功效或是使液相疏散细化，扩大液相触碰总面积，扩大传质指数跟反应速率。

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 mixing effect of the concrete mixer may refine the liquid phase evacuation, expand the total contact area of the liquid phase, and expand the mass transfer index and reaction rate.

但是这时候并不一定要求全罐里都做到匀称的疏散情况，而仅有在罐里的部分地区，比如搅拌离心叶轮的相邻，有明显的疏散功效，使罐里液体次序循环历经这一地区造成传质与反映，然后再循环流到罐里其他地区就很有可能了。因而很有可能说，使疏散相细化疏散，并在罐里导致循环流动性，这就是不互溶液体搅拌过程对搅拌的基本上要求，关键的便是要求搅拌有细化疏散的功效。

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.
