豆奶粉粉体流变仪的概念
一.功能描述Functional description：
通过分析粉体剪切动态数据来描述流动行为表征，粉体工业在加工、存储、运输、料仓中常出现拱架/鼠孔结构；物料之间及物料与固体壁面的摩擦；在料斗的设计中，排料口的大小、料斗壁的倾斜角以及粉料对料斗壁的压力，设计不合理的料斗会给生产造成很大的困难；这些影响粉体流动性的行为特征通过测量粉体内部强度、流动函数、摩擦函数、密度、时间函数等数据分析上述现象和状态. 采用PC软件建立数据模型实时分析.
The flow behavior characterization is described by analyzing the powder shear dynamic data. The powder industry often has arch/rat hole structure in processing, storage, transportation ａnd silo; friction between materials ａnd materials ａnd solid wall; in hopper design In the middle, the size of the discharge opening, the inclination angle of the hopper wall, ａnd the pressure of the powder on the hopper wall, the irrationally designed hopper will cause great difficulty in production; these behavioral characteristics affecting the fluidity of the powder are measured by measuring the inside of the powder. Strength, flow function, friction function, density, time function ａnd other data analysis of the above phenomena ａnd states. Real-time analysis of data models using PC software.
