Abstract It has been shown recently that addition of barley grains to human nutrition translates into many benefits to the health. Therefore the purpose of this paper was to characterize the barley grains through the pearling process. The barley grains were dehulled on the rotatory drum with abrasive wall. The measured properties evaluated the physical, flow and fluid dynamic characteristics of barley grains at different levels of the pearling process. A maximum of (49.08 ± 5.25)% mass-fraction removal was achieved, this meaning that all four commercial levels of pearling, ranging from 11% to 34%, could be sampled. This range of pearling process caused about 40% of reduction in thickness, 25% of reduction in the bulk porosity, 30% reduction in permeability and 17% reduction in the angle of repose. Barley grains were influenced in the pearling process kinetics and consequently in the physical properties and altering the particle-particle and fluid-particle interactions.

不同级别珠光工艺中大麦粒的表征

摘要 最近已经表明，在人类营养中添加大麦谷物对健康有许多好处。因此，本文的目的是通过珠光过程来表征大麦粒。大麦粒在带有研磨壁的转鼓上脱壳。测量的特性评估了大麦粒在珠光过程的不同水平下的物理、流动和流体动力学特性。实现了最大 (49.08 ± 5.25)% 的质量分数去除，这意味着可以对所有四种商业级别的珠光进行采样，范围从 11% 到 34%。这一范围的珠光工艺导致厚度减少约 40%，体孔隙率减少 25%，渗透率减少 30%，休止角减少 17%。
