Determinação das propriedades físicas dos grãos do urucum (Bixa orellana L.) para elaboração de projetos de pressões e fluxo em silos.

Abstract

The objetive of this research was to determine the annato physical properties. The tests were performed utilizing the TSG 70-140 machine, that is known over the world as Jenike Shear Cell. The following properties were determined: particle size, density, interface friction angle, angle of effective friction, friction angle of silo wall and flow function.
