Sažetak
The object of the sieving process is to separate a mixture of a granulated material into fractions. Each fraction contains particles of similar dimensions. The primary object of this research was to determine how the change of sieving amplitude affects the particle size distribution and definition of optimal fraction for processing of direct expanded extrudates based on corn fl our. Sieving analysis was done by”Analisette 3“shaker, model Pro sieve opening sizes were 355, 315, 250, 200, 160, 125, 100 and 63 μm. Sieving of each sample was done by three different amplitudes: 1.5, 2.0 and 2.5 mm. Results are presented as histograms. It is shown that higher amplitude causes better results in particle size distribution, because it allows breaking of the agglomerates that leads to fractions applicable for extrusion processing.
