Description

Technical Field

[0001] The present invention relates to the technical field of Chinese medicinal material processing and detection, and in particular to a moisture detection device, a detection method and a Chinese medicinal material processing system. Background Art

[0002] Moisture detection devices play a vital role in many fields such as industrial production, agriculture, food processing, and pharmaceuticals. Traditional moisture detection methods mainly include weight loss method, distillation stratification method, gas chromatography analysis method, etc. Among them, the working principle of the gravimetric moisture detection device is mainly based on the drying loss method. The moisture content of the sample is determined by measuring the change in weight of the sample before and after heating. The device has a built-in high-precision weighing sensor to record the initial and heated weight of the sample. During the heating process, the weight change of the sample is monitored in real time. Finally, the moisture content is calculated by comparing the initial weight and the weight after heating. The gravimetric moisture detection device has been widely used in many industries due to its wide adaptability and low cost. Compared with the traditional drying method, the modern gravimetric moisture detection device can complete the moisture determination of the sample within a few minutes. This greatly improves the detection speed and reduces the waiting time. The gravimetric moisture detection device realizes fast and high-precision moisture content detection through the principle of drying loss method.

[0003] Food industry: Detect moisture content in foods such as flour, grains, coffee, tea, meat, etc. to ensure food safety, quality and storage period. Moisture content control helps prevent mold growth and maintain food freshness. Pharmaceutical industry: Used to monitor the moisture content of pharmaceutical preparations (such as tablets, capsules), raw materials and excipients to ensure the stability and effectiveness of drugs. Too high or too low moisture content will affect the dissolution rate and efficacy of drugs. Chemical industry: Used to detect moisture content in various chemicals (such as crude oil, paint, solvents) to ensure product quality and production safety. Moisture content control helps optimize chemical reaction processes and improve yield and quality. Agriculture: Used to detect moisture content in samples such as seeds, grains, and soil to guide agricultural production and grain storage management. Appropriate moisture content can increase seed germination rate and reduce the occurrence of pests and diseases. Building materials: Used to detect moisture content in building materials such as wood, cement, and bricks to ensure the strength and durability of the materials. Excessive moisture content may cause the material to swell and deform, affecting the stability of the building structure. Textiles: Used to detect moisture content in cotton, linen and other fiber products to ensure the quality and storage conditions of textiles. Proper moisture content can increase the flexibility and spinning performance of the fiber.

[0004] In the processing of Chinese medicinal materials, it is necessary to carry out steps such as preparation and processing of Chinese medicinal materials, and it is often necessary to test the moisture content of Chinese medicinal material samples. Conventional weighing method moisture detection devices mostly use heat source heating and drying. Due to the accumulation of medicinal materials in the weighing method moisture detection device, the temperature of the heat source drying is too high, which will cause some Chinese medicinal material samples to be charred and lead to inaccurate measurement. Low-temperature drying will cause the detection time to be too long and the detection efficiency to be low. Summary of the invention

[0021] The control terminal calculates the water content and moisture content rate of the Chinese medicinal materials based on the weight data of the Chinese medicinal materials obtained through several weighings transmitted back by the weighing platform.

[0022] A Chinese medicinal material processing system uses the above-mentioned moisture detection device.

[0023] Compared with the prior art, the present invention provides a moisture detection device, a detection method and a Chinese medicinal material processing system, which have the following beneficial effects:

[0024] 1. This moisture detection device can heat and dry the material contained in the containing cylinder by controlling the electric heater through the control terminal. While the material is being heated and dried, the active exhaust mechanism exhausts the air inside the detection chamber. At the same time, the toggle mechanism operates synchronously with the active exhaust mechanism to flatten the material contained in the containing cylinder, thereby ensuring the distance between the material and the heating source, avoiding the material from being overheated and coked, thereby effectively ensuring the accuracy of the moisture detection of the material, and also being able to set the electric heater at a higher power to ensure the drying efficiency of the material; each time the weighing platform weighs the containing cylinder and the material, the magnetic attraction driving mechanism disconnects the magnetic attraction, the toggle mechanism resets, and the exhaust mechanism stops, and the weighing platform can output the weight of the material obtained each time to the control terminal, thereby being able to avoid interference with the weighing accuracy of the weighing platform by stopping each action part, and effectively ensuring the stability and accuracy of each weighing of the weighing platform.

[0025] 2. In this moisture detection device, when the electromagnet is energized to generate magnetism, the magnetic force generated at both ends of the electromagnet attracts each magnetic block and the magnetic plate respectively. Under the action of the magnetic force, each magnetic block overcomes the elastic force of the limit spring, and the magnetic plate overcomes the gravity of the entire internal cylinder. The bottom end of the internal cylinder is separated from the top end of the weighing platform, and the distance between the internal cylinder and the toggle piece is the smallest. The toggle piece extends into the interior of the internal cylinder. At this time, through the rotation of the toggle piece, the material inside the internal cylinder can be continuously toggled and flattened, which can effectively ensure the uniformity of heating of the material and avoid coking of the material due to high heat. It can also maximize the heating efficiency of the electric heater while avoiding coking of the material. At the same time, the bottom end of the internal cylinder can be separated from the top end of the weighing platform, and the downward pressure generated by the rotation of the toggle piece can be avoided to affect the weighing accuracy of the weighing platform.

[0026] 3. In this moisture detection device, the driving motor can output the rotation speed to the toggle member through the transmission shaft, and the toggle member can move along the axial direction of the transmission shaft under the restriction of each limit protrusion and each limit groove, and the toggle member can also rotate synchronously with the rotation of the transmission shaft under the restriction of each limit protrusion and each limit groove, so that the driving motor can drive the exhaust blade and the toggle member to rotate at the same time, and at the same time, when the electromagnet is energized to generate magnetism, the magnetic plate overcomes the gravity of the entire internal cylinder, and the top of the internal cylinder fits with the sealing rubber ring. The material contained in the internal cylinder is restricted inside the internal cylinder by the sealing rubber ring and the toggle member, which can effectively prevent the material from escaping from the internal cylinder and affecting the accuracy of moisture detection.

[0027] 4. In this moisture detection device, since the shell of the air intake filter box is an elastic structure, the air intake filter box can be embedded in the receiving groove when the detection base and the detection cover are closed, so that under the negative pressure generated by the active exhaust mechanism, the outside air can only enter the inside of the containing cylinder after being dried through the air intake filter box, thereby avoiding the influence of the outside humid air on the moisture content detection of the dried material.

[0043] Embodiment 2:

[0044] Please refer to Figure 1-Figure 9, which is different from the above-mentioned embodiment, is that the toggle mechanism 8 comprises a fixed plate 81, a transmission shaft 82 and a toggle member 83, the transmission shaft 82 is rotatably connected to the fixed plate 81, and the two ends of the transmission shaft 82 respectively pass through the two side surfaces of the fixed plate 81, and the toggle member 83 is sleeved on the end of the transmission shaft 82 close to the containing tube 4; a plurality of limiting protrusions 831 are arranged inside the toggle member 83, and a plurality of limiting grooves 821 are opened on the outer wall of the transmission shaft 82, and each limiting protrusion 831 can be embedded in a limiting groove 821; the toggle member 83 can move along the axial direction of the transmission shaft 82 under the restriction of each limiting protrusion 831 and each limiting groove 821, and the toggle member 83 can also rotate synchronously with the rotation of the transmission shaft 82 under the restriction of each limiting protrusion 831 and each limiting groove 821.

[0045] A mounting ring groove 811 is provided on one side of the fixed plate 81 close to the toggle member 83, and a follower ring plate 812 is provided inside the mounting ring groove 811. The follower ring plate 812 can rotate around the axis of the fixed plate 81 inside the mounting ring groove 811; a plurality of limit springs 84 are provided between the follower ring plate 812 and the toggle member 83, and the two ends of the limit spring 84 are respectively fixed between the follower ring plate 812 and the toggle member 83; the rotation of the toggle member 83 can be transmitted by each limit spring 84, thereby driving the follower ring plate 812 to rotate with the toggle member 83.

The toggle member 83 can also rotate synchronously with the rotation of the transmission shaft 82 under the restriction of each limiting protrusion 831 and each limiting groove 821, so that the driving motor 93 can simultaneously drive the exhaust blade 94 and the toggle member 83 to rotate, and at the same time, when the electromagnet 72 is energized to generate magnetism, the magnetic plate 421 overcomes the gravity of the entire internal cylinder 42, and the top of the internal cylinder 42 fits between the sealing rubber ring 22. The material contained in the internal cylinder 42 is restricted inside the internal cylinder 42 through the sealing rubber ring 22 and the toggle member 83, and the material can be effectively prevented from escaping from the internal cylinder 42 and affecting the accuracy of moisture detection.
