Excessive milling of rice kernels will result in nutrient loss and grain waste. To avoid grain waste, multibreak milling systems have been widely used in large-scale commercial rice mills. However, there is still no reasonable breakpoint planning method to guide the multibreak milling process. To construct a reasonable multibreak milling system, in this research, taking rice milling, a typical heterogeneous cereal-kernel milling process, as an example, the multivariate analysis method was used to comprehensively analyze the characteristic changes of milled rice during the whole milling process. A breakpoint planning method was established, including planning the number of breakpoints, determining the degree of milling or milling time corresponding to each breakpoint, and estimating the actual breakpoint to which the milled rice belongs. The verification results showed the rationality and high accuracy of the planning method. The presented work will help operators to plan the multibreak milling system of rice efficiently and objectively so as to significantly improve the commercial value of milled rice.
过度碾磨米粒会导致营养成分流失和粮食浪费。为避免粮食浪费，多段碾磨系统已在大型商业碾米厂中广泛使用。然而，目前仍没有合理的断点规划方法来指导多段碾磨过程。为构建合理的多段碾磨系统，在本研究中，以典型的异质谷物籽粒碾磨过程——大米碾磨为例，采用多元分析方法全面分析了整个碾磨过程中大米的特性变化。建立了一种断点规划方法，包括规划断点数量、确定每个断点对应的碾磨程度或碾磨时间，以及估计碾出大米所属的实际断点。验证结果表明了该规划方法的合理性和高精度。所开展的工作将有助于操作人员高效、客观地规划大米的多段碾磨系统，从而显著提高碾米的商业价值。
