摘　　要：设计一种果粒饮料储液搅拌缸,对储液搅拌缸缸体、搅拌桨结构进行设计,并给定其各项参数。采用正交试验法与FLUENT相结合进行数值模拟,确定搅拌桨安装高度、搅拌桨叶片直径、搅拌桨的旋转速度等因素对搅拌过程的影响程度,并对储液搅拌缸进行参数优化,得到最佳参数解。结果表明:影响储液搅拌缸搅拌稳定后果粒浓度幅值的因素主次顺序为:桨直径、搅拌速度、下层桨高度。研究成果可为后续的果粒饮料一体化灌装机的设计提供参考。A fruit grain beverage liquid mixing tank was designed in this study, including the structure of the cylinder block and the mixing paddle, and related parameters were provided. The numerical simulation was carried out by orthogonal test and FLUENT, to determine the influence degree of the factors, such as the installation height of the agitator, the diameter of the impeller and the rotation speed of the propeller, and the parameters of the stirred tank, were optimized to obtain the optimal parameter solution. Results： The main order of the factors that influenced the stability of the agitator concentration was as follows, the diameter of the paddle, the stirring speed, the height of the lower paddle. The results in the present study could provide contribution to the follow-up design of fruit juice beverage filling machine.
