[0002] Loss on drying testing is used to detect the moisture content in an object. The object to be tested loses a certain amount of water during evaporation and volatilization. Accurate loss on drying data can be obtained based on the change in mass.

[0003] For example, the utility model patent with application number CN201920560653.3 proposes a food drying weight loss detection device, in which a combination structure of a bottom plate, a supporting platform, and a placing table is set inside the drying equipment. When in use, the placing table is slid out, the food to be dried is placed in it, and then it slides back into the drying equipment. At this time, the set weight sensor monitors the food quality in real time. After the weight loss ratio is input to the controller through the control button, the controller automatically calculates the food weight loss value, and then automatically controls the electric control switch to power on, so that the drying equipment is powered on and running. When the actual measured value of the weight sensor reaches the weight loss value, the information is transmitted to the controller. The controller sends an instruction to the signal encoder to edit the power-off instruction and then transmits it to the electric control switch. The electric control switch is powered off and the drying equipment stops running. At the same time, the control relay is energized to make the alarm sound an alarm to remind the staff that the drying is completed.

[0022] The prepared material is introduced into the drying box 100 through the feed exhaust pipe 300. The rotation of the rotating plate 200 can evenly disperse the material into the drying box 100. At the same time, the scraping end of the scraping assembly 400 rotates accordingly. When the material accumulates to a certain thickness, the scraping end can flatten the material to make the material laying thickness uniform, which is convenient to use. The drying box 100 is heated and water vapor is discharged from the feed exhaust pipe 300. After a certain period of time, the weight after drying loss can be obtained by weighing.

[0023] The drying box 100 in this embodiment provides a space for drying chemical crystalline powder.

[0024] In one embodiment, the drying box 100 includes a box body 110 and a box cover 120. The interior of the box body 110 forms a drying chamber. The top of the box body 110 is open. The box cover 120 is threadedly connected to the box body 110 to open and close the opening, thereby facilitating the cleaning and inspection of chemical crystalline powder inside the box body 110.
