Ternary milling of bulgur with four rollers Original Research Article

In this study, the effect of ternary roller mill (four rolls and three gaps) on the selected quality parameters of bulgur was researched. Particle size, colour (L, a, b and YI-values), ash content, hectolitre-weight, yield and loss were evaluated for the roller mill. The first (between first and second rollers: 1.9 mm), second (between second and third rollers: 1.2, 1.0 and 0.8 mm) and third (between third and fourth rollers: 0.4, 0.5 and 0.6 mm) gaps were arranged to determine the optimum parameters. The products obtained were classified as coarse (+/3.5), pilaf (3.5/2.0), medium (2.0/1.0), fine (1.0/0.5) and undersize (0.5/−) using 3.5, 2.0, 1.0 and 0.5 mm circular sieves.
