[0069] The working principle and usage process of this utility model are as follows: Before drying the material, the relevant information of the material is entered into the computer. The equipment automatically weighs the empty trays according to the input order. After weighing the empty trays, the first empty tray stops at the loading port. The automatic loading device at the loading port is opened, and the material is poured into the tray. The weighing button is pressed, and the equipment automatically weighs the gross weight before moving to the next target tray. The above operation is repeated until all the entered trays are filled. The equipment then automatically switches to drying mode, adding material to the trays after drying is complete.

[0070] The sample is dried in a constant temperature drying oven at 105℃-110℃ under forced air conditions. Automatic weighing is performed every 10 minutes (adjustable from 10 to 30 minutes). Comparison begins after 1.5 hours of drying. Constant weight is considered achieved when the current weight loss is less than 0.5 grams (adjustable from 0.1 to 0.5 grams) or greater than the data from half an hour ago. The total weight loss at this point represents the moisture content of the sample. A moisture curve is automatically generated by the host computer. Data is automatically saved for future retrieval or network transmission. Once all material is dried, the real-time status screen displays "completed." The user can then select "unload" on the computer, and the system automatically unloads the material into the hopper.

[0071] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
