[0002] With the development of scientific research and the progress of production technology, the quantitative analysis of moisture has been listed as one of the basic items in the physical and chemical analysis of various substances. As an important quality index of various substances, moisture is a commonly used detection item for drugs, and is often applied to the inspection of raw materials or their preparations. It has a wide range of applications in the field of drug detection and has been widely included in the pharmacopoeias of various countries. The level of moisture determination in a testing laboratory can objectively and representatively reflect the drug detection ability of the laboratory.

[0003] When the existing moisture determination device is in use, first, the storage tray for storing drugs is placed on the electronic scale and the electronic scale is set to zero. Then, the drugs that need moisture determination are placed on the storage tray, and the drugs are weighed. Then, the storage tray is moved into the drying device for drying treatment. Since the drugs are stacked on the storage tray, when the drying device dries the drugs, it is not convenient to dry the drugs inside the stacked drugs, and the drying effect of the drugs is poor, reducing the accuracy of drug moisture determination. In addition, after drying the drugs on the storage tray, the storage tray needs to be carried to the electronic scale. Since the storage tray absorbs heat during the drying process of the drugs, the temperature of the storage tray is relatively high, and it is easy to scald the hands of the staff during the process of carrying the storage tray.
