PHYSICAL AND FLOW PROPERTIES

The Brazilian agricultural production exceeds the storage capacity, so the construction of silo becomes essential. s physical and flow characteristics of the analyzed product is essential in the silo design. Given this, the present work aims to determine the physical and flow properties of different bean cultivars for sizing of vertical silos. The experiment was conducted in the Laboratory of Rural Constructions and Environment- LACRA of the Federal University of Campina Grande, in the municipality of Campina Grande-PB, in the period from December 2014 to January 2015, analyzing different types of beans: carioquinha (Phaseolus vulgaris L.), black (Phaseolus vulgaris L.) and macassar (Vigna unguiculata). The physical characteristics (moisture content, granulometry, density) and flow (angle and effective angle of internal friction, average cohesion and friction angle existing between the product and different wall materials of the silo) were measured, the following wall materials were used: acrylic, smooth steel, rough steel, aluminum, wood, analyzing the best option.
