In this paper, the effect of total solid content in slurry, inlet temperature and outlet temperature of spraying drier on the yield of cheese powder were analyzed by orthogonal rotational regression design. The regression equation was established and the spraying drier conditions were optimized. 针对影响干酪粉出品率的喷雾干燥条件,采用三因素二次通用旋转回归设计对其进行了优化,并建立了回归方程。
At all times, the slurry leakage in the feed inlet of the autogenous tumbling mill chiefly influences the operation efficiency of the mill, which affects the production, quickens the abrasion of the quill shaft, increases the maintenance time and decreases the lifespan of the mill. 自磨机进料端漏浆问题一直是影响自磨机运转率的主要原因,它影响生产,加剧中空轴的磨损,增加维修时间又降低设备的使用寿命。
In order to make suggestions for engineers and researchers who work in pump industry to calculate NPSH, the causation of cavitation occurred in a slurry pump theoretically is analyzed. The relationship between NPSH and inlet geometry parameters of impeller is analyzed. 从理论上分析了泵内产生汽蚀的原因,在对离心式渣浆泵与普通离心泵汽蚀特性比较的基础上,分析了渣浆泵汽蚀余量与叶轮入口几何参数关系;
