Análise de fluxo de ração e farelo de trigo em silos prismáticos industriais.

Abstract

With the aim of evoluate the behavior of the flow of the avian ration and wheat bran, it was made a reduced model of prismatic silos with a zigzag conformation of transparent material. The present work also had as objectives to determine the medium outflow of bulk solids, as well as their physical properties: humidity proportion, granulometry, consolidated density, angle of internal friction, effective angle of internal friction, kinetic angle of friction on a wall surface, flow function and flow factor. For the obtention of the results of the analysis, were made photografic sequencies of the original product inserted by layers of bulk solids stained in red. For the medium flow of discharge it was adopted the statistical delineation entirely casualized with factorial arrangement 3 x 3 x 2 (fat proportion, relation height/side and transversa! section of the mouth of exit), with three repetitions. The obtained results showed that the increased fat proportion and the transversal section of the mouth of exit influenced in the kind of flow of the studied bulk solids.
