衡量谷物干燥机干燥效果的一个重要指标是粮食经干燥后降水值的大小。利用计算机控制系统 ,能方便地改变参数 ,选择合适的控制方式 ,保证谷物的干燥效果。国外有利用谷物干燥时排出的湿空气的湿度间接检测水分的 ,这只是在干燥机处于稳定的理想状态下使用 ,而在实际生产过程中 An important indicator of the drying effect of cereal dryers is the amount of precipitation after drying. The use of computer control system, can easily change the parameters, select the appropriate control methods to ensure the drying effect of cereals. Foreign countries use the humidity of the wet air discharged when the grain is dry to indirectly detect the moisture, which is only used when the dryer is in a stable ideal state. In the actual production process
