Method and device for judging water content of material in microwave drying process

The invention belongs to the field of online monitoring, and particularly relates to a method and a device for judging the water content of a material in a microwave drying process, which are used for obtaining the water content of a water-containing thin-layer medium in a drying process in a power microwave field. The method is a real-time and online moisture content judgment method in the power microwave drying process, the characteristics of reflected waves and transmitted waves do not need to be detected, and the method has a structure and a method different from those of a previous method. The relationship between the temperature change rate of the water-containing thin-layer medium and the water content in the microwave drying process is theoretically deduced, and thin-layer medium microwave drying experiments of various different materials are carried out, so that the effectiveness of the method is proved. 本发明属于在线监测领域，具体涉及一种微波烘干过程中物料含水率的判断方法及装置，用于功率微波场内获取含水薄层介质干燥过程含水率。本发明为功率微波烘干过程中实时、在线的含水率判断方法，不需要检测反射
