高剪切均质机的均质机理混料、杀菌、均质是冷饮生产中必不可少的环节。按传统的生产工艺，以上环节许混料缸、冷热缸、高压均质机三台设备才能完成，并需配备管道、阀门、泵等配件，生产工艺繁琐。其中，高压均质机有许多不可避免的弊端：均质阀、密封件非常容易磨损，寿命短，一般仅使用三个月左右，弹簧件寿命更短，需经常更换。高剪切均质机的工作原理高剪切均质机结构由定子、转子组成。定子是有数道齿圈组合而成，其作用原理是高速旋转的转子产生很大的离心力，同时产生异乎寻常的速度变化，使物料受到急剧的剪切、压缩和拉伸作用后得到有效的分散、混合、均质、乳化。高剪切均质机与高压均质机作用的区别：名称高剪切均质机高压均质机原料要求粉状物、块状料或水果可直接投入必须先将物料融化混合为流体后方可均质易损耗件两年内无需更换配件，无易损件均质阀、密封件使用两、三个月便需要经常更换生产操作灵活、简便、无需专人操作需专人操作、调节耗能耗电量为高压均质机的1/3耗电量高，能源浪费适应范围适用范围广不适宜高粘度的物料酸碱性适应性强适应性弱均质效果均质细度可达1μm以下，稳定性好均质细度只达到2-3μm，稳定性差综合效果混料、杀菌、均质同时完成只能单独均质用清洗方法自动清洗清洗复杂高剪切均质机与高压均质机的均质机理的比较：比较高剪切均质机高压均质机宏观均质机理剪切作用主要通过液滴在高速旋转的转子和定子间的间隙内被剪切，以及由此间隙和转子——定子上小孔射流的综合效应来实现。料液在高压下流过缝隙时，液滴先是被延伸，后因通过阀时的涡动作用，使延伸部分剪切拉碎。撞击作用高速旋转的液滴受惯性离心力的推动，具有极大的冲击力，因而产生撞击作用。在均质阀缝隙中高速冲出的液流出口处置有挡圈，因而产生高速撞击作用。空穴作用离心力的作用使未进入环隙时的液体具有一定压力，而进入环隙后成为高速旋转液流，液体离开定子小孔后压力又回升，所以也有一定的空穴效应液流进口处静压很高，过狭缝时，静压能转化为动能，压力迅速大幅度地下降，在其缝隙内瞬时引起空穴现象，离开缝隙后压力的回升又使空穴消失，因而使液滴破碎微观均质机理高剪切均质机高速旋转时的液滴流动状况相当复杂，主要受控于作用在液滴表面不断变化的流动速度和由此产生的脉动压力，从而发生了分裂液滴的张力，使液滴破裂。高压均质机提供给液滴破裂的能量来自于料液在进口处携带的极高静压能。
