CIP清洗程序1.冷管路及其设备的CIP清洗程序乳品加工中的冷管路主要包括收乳管线、原料乳贮存罐等设备。牛乳在这类设备和连接管路中由于没有受到热处理,所以相对板结垢较少。建议的清洗程序如下:水冲洗3~5min。用75~8℃热碱性洗涤剂循环1~15min(若选择氢氧化钠,建议溶液浓度为.8%~1.2%)。冲洗3~5min。建议每周用65~7℃的酸液循环一次1~15min(如浓度为.8%~1.%的硝酸溶液)。

叶轮也称为工作轮,是离心式鼓风机中重要的一个部件。气体在叶轮叶片的作用下,跟着叶轮作高速旋转。而气体由于受到旋转离心力的作用,以及在叶轮里的扩压流动,使气体通过叶轮后的压力得到了提高。此外,气体的速度能也同样是在叶轮里得到了提高。可以认为叶轮是使气体提高能量的途径。叶轮按照结构形式可以分为开式、半开式和闭式三种,在大多数情况下,后两种叶轮在鼓风机中得到了广泛的运用。叶轮根据弯曲形式不同,分为前弯式、后弯式和径向式三种。
