Description

TECHNICAL FIELD

[0002] In the process of full moisture testing of coal and other solid samples, the sample is weighed and dried in a sample tray, and then weighed again after drying. The moisture content of the sample is calculated by the difference in weight between the two weighings. Finally, the sample tray containing the discarded sample is disposed of. Some existing full moisture testing systems directly throw the sample tray containing the sample into the garbage can when disposing of the discarded sample, which can cause the discarded sample to splash everywhere. Additionally, the sample tray and discarded sample are mixed together, and the sample tray contains a large amount of waste sample, which requires a large amount of cleaning work.
