Calculation of the Residence Time of Dispersed Phase in Sectioned Devices: Theoretical Basics and Software Implementation

The article deals with a model of calculation the residence time of particles in the granulating and drying devices with vertical sectioning of the working space. The algorithm of calculation the residence time in the granulating and drying devices workspace is described. The model is realized the implementation the author’s software product Multistage Fluidizer®. The software product enables to automatize calculation simultaneously by several optimization criteria and to visualize calculation results in the form of 3D images. The perforated shelf constructive parameters impact and fluidized flow during the residence time in the device are fixed. The research proposed the way of defining the particle’s residence time in the workspace of the granulating and drying devices in free (without consideration of cooperation with other granules and granulator’s elements) and constrained motion regimes. The engineering computation of sectioning devices methodology with fluidized bed of particles is based on the calculation results. The automated calculations results give a base of designing industrial granulating and drying devices.
