摘要

储粮仓内的盘存和外源分布是管理储粮的一个重要因素。粮仓内DFM的分布是由籽粒装载过程中DFM的分离机制决定的。从中央喷口将谷物装入筒仓是粒状物料堆流的一种特殊情况。然而,我们对堆流的理解仍在不断发展,目前还没有模型可以预测粮食筒仓中的堆积和外来物质分布。在查阅大量文献的基础上,确定了粮仓中央喷口灌浆过程中DFM分离的主要机制和影响DFM分布的主要因素。分析了DFM的分布规律。综述了分析DFM分离和分布的实验方法。总结了我国在偏析机理和偏析影响因素方面存在的不足,并对今后的研究方向和挑战进行了讨论。

A Review of Distribution and Segregation Mechanisms of Dockage and Foreign Materials in On-Farm Grain Silos for Central Spout Loading
Dockage and foreign material (DFM) distribution in grain silos is an important factor in managing stored grain. The DFM distribution in grain silos is dictated by the segregation mechanisms of DFM during grain loading. Loading grain into silos from a central spout is a special case of heap flows of granular materials. However, our understanding of heap flows is still evolving, and no models are currently available to predict the dockage and foreign material distribution in grain silos. Based on an extensive literature review, this paper identified the dominant mechanisms of DFM segregations during central spout filling in grain silos and main factors influencing DFM distribution. The DFM distribution patterns were characterized. The experimental methods for analyzing DFM segregations and distribution were also reviewed. The gaps of our knowledge on segregation mechanisms and factors influencing segregation were summarised and future research directions and challenges were discussed.
