Different sieving methods for determining the physical characteristics in ground corn

We evaluated various sieving methods to estimate particle size (PS) and geometric standard deviation (GSD) of ground corn. The corn had been previously divided in six fractions each one a hammermill (1-, 2-, 3-, 4-, 5- or 12-mm sieves). stacked method, with prior drying at 105ºC without agitators was the reference. eight methods, distributed factorial design (2 x 2 6), consisting following treatments: i) (two 25-mm rubber spheres), ii) previous drying, iii) nest test sieves set reverse, iv) employing degrees, totaling 48 treatments (four replicates). There linear increase PS estimation for stacking quadratic increases others. Reverse, agitator methodologies gave better corn, consequently lowest highest GSD. results were more pronounced high-intensity grinding (hammermill sieve small apertures) which differences between reference method reverse up 210 µm. Reverse combined allowed greatest passage particles through promoted characterization
