摘　　要：散粮堆的平均密度是粮食库存数量实时在线检测的重要参数。为解决粮食加工企业库存数量盘点中存在的散粮堆平均密度取值难题,在对比分析了现有方法的基础上,提出了一种适用于粮食加工企业进出仓作业频繁的筒仓散粮堆平均密度计算方法,并选取一个稻谷筒仓的完整进出粮过程,对该方法的测量精度和实用性进行实验验证,结果满足使用要求。该方法简单实用,精度较好,克服了现有修正系数法的不足,为粮食加工企业动态库存数量盘点提供了技术手段。The average density of particulate grain pile is an important parameter for real-time online measurement of grain stock quantity. In order to solve the problem of calculating the average density of particulate grain pile in the inventory of grain processing enterprises, a calculation method for the average density of particulate grain pile in silos was proposed based on the comparison and analysis of the existing methods. Besides, a complete process of grain filling and discharging o f a rice silo was selected to verify the measurement accuracy and practicability of the method. The results shows the method meet the requirements of use. This method is simple, practical, and accurate. In addition, the method overcomes the shortcomings of the existing correction coefficient method and provides technical means for dynamic inventory count in grain processing enterprises.
