[0035] When using the present invention, the chitosan oligosaccharide sample is first placed on the sample tray, and then the sample tray is placed on the weighing platform 3 for weighing, and the initial sample mass displayed on the display screen 4 is recorded. Then, the cover 2 is pushed to move to the left to close the connecting support frame 1, and then the heating wire 5 is controlled by the controller 6 to heat, and the chitosan oligosaccharide sample on the sample tray is dried. After drying for a certain period of time, the heating wire 5 stops heating, and then the mass of the dried sample displayed on the display screen 4 is recorded, thereby achieving the effect of automatically completing the drying and weighing of the chitosan oligosaccharide sample without moving the sample tray, with strong automation, saving manpower, and improving detection efficiency.

[0039] The knocking assembly of the device can be used to knock on the sample tray. When the covering cover 10 rotates, the knocking column 22 is driven to rotate. When the knocking column 22 contacts the clamping frame 21, the knocking column 22 rotates outward, and the torsion spring 23 is deformed. After the knocking column 22 is separated from the clamping frame 21, the torsion spring 23 recovers, so that the knocking column 22 is reset to knock on the sample tray, thereby causing the sample tray to vibrate and preventing the chitosan oligosaccharide sample from adhering to the sample tray.
