[0002] In order to understand the status of soil environmental quality, it is necessary to test the soil. Soil testing generally includes preparation, site layout, sampling, sample preparation, analysis and testing, and evaluation. The water content in the soil is very important for many soil and environmental studies. Excess water may interfere with the experimental results. Therefore, it is necessary to fully remove the water in the soil before the experiment, and when the soil samples are in a dry state, they can be more easily stored and preserved. Before conducting experiments and analyses, soil samples need to be prepared and preserved. However, existing drying devices generally do not have a rotation function. Soil samples are heated unevenly at different positions in the drying device, and the consistency of the water content in the sample cannot be guaranteed. The extracted humid air cannot be reused, and the heat energy consumption is large, which is not energy-saving and environmentally friendly. Utility Model Content
