不同载体对微量元素预混料质量的影响

Effects of Different Carriers on the Quality of Trace Element Premix

在相同工艺条件下 ,对石粉、酒糟粉、细稻壳糠、元明粉、石膏粉等 5种常用载体进行比较试验研究。试验结果表明 :不同载体对微量元素预混料的混合均匀度、振动分级、抗结块、抗防潮以及I-和Fe2 + 的贮藏稳定性等指标的影响均存在差异。综合考虑各项指标 ,细稻壳糠为最优载体。

A comparative study was carried out for five kinds of carriers i.e. limestone powder, distiller's grain meal, gypsum powder, finely ground rice hull and Na_2SO_4 under the same technological conditions. The result showed that different carriers were different in their effects on such quality indexes as CV, classification due to vibration, anti-caking property, dampproof property and the storage stability of I^- and Fe^(2+). Judging comprehensively, finely ground rice hull was the best carrier.
