If it is not roasted dry at one time, the moisture content does not meet the standard and needs to be roasted dry again, the "start" key should be pressed, and the system will repeat the roasting and drying detection according to the preset process. The calculation of the moisture content will still use the initial weight collected during the first detection.

[0124] 5. After the detection is completed, the roasted sample sand and gravel can be poured out with a special sand bag.

[0125] 6. Data upload. When data needs to be uploaded, the relevant data (sand and gravel loading vehicle information, sand and gravel moisture content) is uploaded.

[0126] 7. Click the "manual debugging" key to enter the manual debugging interface, and click the button to perform the corresponding operation.

[0127] The following parameters can be set in the parameter setting:

[0128] Manual rotation speed: set the rotation speed in manual state, the default value is 1000.
