[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The main existing technologies are: loss on drying method (oven method), capacitive moisture detection, infrared drying method, microwave moisture detection, and near-infrared spectroscopy analysis.

[0029] The drying loss method (oven method) evaporates the water in the sample by heating, and then calculates the moisture content based on the change in mass of the sample before and after heating. The advantage of this method is that the results are reliable, but the disadvantage is that it takes a long time to complete the measurement.

[0030] Capacitive moisture detection uses the property that the dielectric constant of a material changes with its moisture content. The presence of water molecules changes the dielectric properties of the material, thereby affecting its capacitance value. By measuring the change in capacitance, the moisture content of the material can be indirectly determined. This method is suitable for online monitoring and non-destructive testing, and is suitable for real-time monitoring in continuous production processes, but the measurement results are often not accurate enough.

[0031] The infrared rapid moisture meter is designed based on the principle of thermal gravimetric analysis, which means that the evaporation of moisture is accelerated through the infrared heating unit and the moisture evaporation channel, so that a constant temperature state can be reached more quickly. Moreover, due to the uniform heating, damage to the sample surface can be reduced, but the measurement accuracy is also low.

[0032] Microwave moisture detector uses microwave energy to penetrate the sample and be absorbed by the water in it, which causes the change of dielectric loss. By analyzing the microwave signal, the moisture content of the sample can be directly obtained. This method has the advantages of fast speed, high sensitivity, and no influence of sample color. It is particularly suitable for liquid and semi-solid samples, but the measurement results are also not accurate enough.

[0033] Near infrared spectroscopy (NIR) is a non-destructive testing technology that determines information about moisture and other components by scanning the near infrared spectrum reflected or transmitted by the sample. NIR technology provides instant results and does not require complex sample preparation procedures. It is very suitable for industries such as food, agriculture and pharmaceuticals, but the measurement accuracy is also low.

[0034] Example 1

[0035] See also Figure 1 As shown, a rapid moisture detection device described in this embodiment includes a screen storage structure 1, a hot air blower structure 2 and a weighing structure 3; wherein:

[0036] The screen material storage structure 1 is used to store the material to be tested;

[0037] Specifically, if Figure 2 As shown, the screen material storage structure 1 includes a screen 11 and a screen cover 12. The material to be tested is placed on the screen 11. Different types of screens 12 are provided according to different materials to be tested; and the screen cover 12 is used to fix them.

[0038] It should be noted that: the material to be tested is placed on the screen 11, and the material can be picked up and delivered manually or automatically with the help of a robotic arm. No matter which picking and delivering scheme is adopted, there is no need to use a crusher to crush the material to be tested, and the test can be carried out directly; for different materials, different types of screens and screen covers are provided to adapt to different processes and be flexibly matched.

[0039] More specifically, an auxiliary fixing assembly 13 that cooperates with the weighing structure 3 and is fixed to the side of the screen 11 is provided on the side of the screen 11 , and the auxiliary fixing assembly 13 is fixed to the side of the screen 11 by bolts.

[0040] The hot air fan structure 2 heats and dries the material to be tested in the screen material storage structure 1;

[0041] Specifically, if Figure 3 As shown, the hot air blower structure 2 includes a hot air blower 21, a slide rail 22 and a hot air blower bracket 23. The hot air blower 21 moves through the slide rail 22, rises upward and lifts up the screen storage structure 1, and moves downward to return to the initial position after heating is completed.

[0042] More specifically, the hot air blower 21 is a barrel-shaped blower with an upper opening, and a screen storage structure 1 is fixedly installed at the upper opening. The hot air blower 21 moves through the slide rail 22, and the slide rail 22 is fixedly installed in a hot air blower bracket 23. The hot air blower bracket 23 is fixed on a lathe.

[0043] The weighing structure 3 cooperates with the hot air blower structure 2 to achieve weighing of the material to be measured before and after heating.

[0044] Specifically, if Figure 4 As shown, the weighing structure 3 includes a weighing sensor 31, a weighing bracket 32 ​​and a screen support plate 33, which separate the drying state from the weighing state to avoid the influence of external factors such as wind, heat, vibration, etc. on the measurement, ensure the stability and continuity of the internal structure of the device, and ensure the weighing accuracy; in addition, the dynamic weighing method is converted into static weighing with high weighing accuracy, and the moisture content of the material is finally obtained through multiple repetitions of structural actions and weighing calculations through automatic control systems and data model statistics.

[0045] More specifically, the screen support plate 33 is a cross-staggered bracket compatible with the hot air blower 21 , is fixed at the cross-staggered position by a weighing bracket 32 ​​, and transfers the weight of the material to be measured in the screen 11 to the weighing sensor 31 .

[0046] It should be noted that: the screen support plate 33 is made of heat-insulating material to avoid unnecessary loss of the weighing structure 3 caused by the residual high temperature after heating, and the weight of the material to be measured in the screen 11 is transferred to the weighing sensor 31 via the weighing bracket 32 ​​to avoid affecting the material weighing; the heat, vibration and buoyancy generated by the hot air blower during the measurement process are separated from the weighing structure and weighing sensor inside the device to avoid the influence of external factors on the material weighing.

[0047] The present invention places the material to be tested in the screen storage structure 1, then starts the hot air fan structure 2 to rise and lift up the screen storage structure 1 for heating and drying. After the heating is completed, the hot air fan structure 2 descends, and the screen storage structure 1 falls back to the bracket of the weighing structure 3, and is weighed and measured after being separated from the hot air fan structure 2, thereby realizing the conversion of dynamic weighing to static weighing, improving the weighing accuracy, and finally obtaining the material moisture content result. This embodiment adopts the drying method of the drying loss method (oven method), evaporates the water in the sample by heating, and then calculates the moisture content according to the mass change of the sample before and after heating, and adopts the hot air fan 21 to replace the existing heat source, which greatly improves the drying efficiency and reduces the measurement time.
