DETAILED DESCRIPTION

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method: Figure 1-5 As shown, a powder material humidity detection device for food processing includes an electronic analyzer body 1, the lower end of the electronic analyzer body 1 is connected to a protective shell, and the lower end of the protective shell is connected to a sampling column 2; a movable frame 3 is sleeved on the protective shell, a buffer block 4 is connected between the bottom end of the electronic analyzer body 1 and the movable frame 3, and a pair of vibration structures 5 are fixedly connected to the movable frame 3; The sampling column 2 includes a fixing frame 201 connected to the electronic analyzer body 1, a hollow column 202 is fixedly connected to the lower end of the fixing frame 201, a rotating ring 6 is rotatably connected to the outer end of the hollow column 202, a plurality of uniformly distributed sampling chambers are arranged in the hollow column 202, and a filter screen 203 is fixedly connected to the opening of the sampling chamber; A stepper motor is installed in the protective shell, one end of the rotating ring 6 located in the protective shell is connected to a gear ring, a driving gear meshing with the gear ring is installed at the power output end of the stepper motor, and a through hole matching the sampling chamber is opened on the rotating ring 6; A detection column 11 is installed on the electronic analyzer body 1, one end of the detection column 11 is connected to the telescopic end of the electric push rod on the electronic analyzer body 1, and the other end of the detection column 11 is inserted into the sampling column 2. A plurality of detection units matching the sampling chamber are equidistantly installed on the detection column 11, and the detection units include infrared detection equipment and microwave detection equipment; a contact humidity sensor is installed on the top of the detection column 11, and the contact humidity sensor includes a humidity-sensitive resistor sensor and a humidity-sensitive capacitor sensor. The initial state of the detection column 11 is to penetrate the sampling column 2 and extend the contact humidity sensor to the outside of the sampling column 2; Infrared detection equipment is suitable for the detection of small particles and thin flakes, and microwave detection equipment is suitable for the detection of bulk granular and high-humidity materials; Since the infrared detection equipment and microwave detection equipment are respectively suitable for the detection of different types of materials, after sampling the material, the material type is identified, and then the corresponding detection unit is moved to the sampling bin for material detection; A partition ring 7 is installed between two adjacent sampling chambers. A through hole matching the detection column 11 is opened in the middle of the partition ring 7. A pair of mounting grooves are opened on the inner wall of the through hole. A gate plate is slidably connected in the mounting groove. An electromagnet is installed at the bottom of the mounting groove. When the electromagnet is working, it attracts the gate plate to make the pair of gate plates move away from each other to open the through hole so that the detection column 11 can pass through. A compression spring is connected between the electromagnet and the gate plate. When the detection column 11 moves away from the partition ring 7, the gate plate is closed to isolate the two sampling chambers. When the detection column 11 passes through the partition ring 7, the gate plate is opened. At this time, the detection column 11 blocks the through hole to separate the two sampling chambers.

[0022] The vibration structure 5 includes a vibration motor 501 installed in the movable frame 3, and a vibration column 502 is installed on the power output end of the vibration motor 501. The length of the vibration column 502 is greater than the length of the sampling column 2. The vibration motor 501 and the vibration column 502 are vibration devices in the prior art. The technicians in this field select suitable vibration motors 501 and vibration columns 502 for installation.

[0023] A weighing sensor is installed in the sampling bin. The vertical plane corresponding to the opening end of each sampling bin is different. After each rotation of the rotating ring 6, it only matches one sampling bin opening. The mesh sizes of the filters 203 on the multiple sampling bins are different. The volumes of the multiple sampling bins are the same. The rotating ring 6 can open the sampling bin at the set position by rotating the set angle, so that the sampling bin at the set position is opened for sampling, and the powder material is filtered through the pre-installed filter 203 with the set mesh size to screen the material whose particle size needs to be detected.

[0024] The electronic analyzer also includes a detection system, which includes a controller, a detection module, a data processing module, a data storage module and a visualization module are connected to the controller, an image recognition unit and a detection data analysis unit are provided in the data processing module, and a display screen matching the visualization module is installed on the electronic analyzer body 1. A small fan is installed in the electronic analyzer body 1, and the output end of the small fan is located on the upper side of the hollow column 202, and the opening at the bottom end of the hollow column 202 is closed by a partition ring 7.

[0025] During the detection of this solution, the device is inserted into the powder material, and the local humidity of the powder material is detected by the contact humidity sensor on the detection column 11. When abnormal humidity in the powder material is detected, the dust is sampled for detection; Before sampling, the vibration structure 5 is turned on to vibrate the material to promote uniformity of the material in the sampling area, and then the sampling bin at the corresponding position is opened for sampling. After sampling, the material is tested in the sampling bin. During the test, the detection column 1 is moved according to the type of dust food so that the corresponding detection unit on it matches the position of the sampling bin, and then the test is performed; Optionally, during sampling, the powder is sampled by classification, and after classification sampling, the dust is image-recognized to identify the dust type, and then the detection units are moved one by one to the sampling bins for detection. After all sampling bins are tested, the material humidity is evaluated based on the test results of all sampling bins.

[0026] This solution can achieve rapid and accurate detection of the moisture content of powdered materials, and samples are taken during the vibration of the materials, ensuring the uniformity and representativeness of the sampling. During the sampling process, the dust type is identified through image recognition technology, and then the appropriate detection unit is selected for detection, so that the detection method is adapted to the type of material to be detected, which is easy to improve the accuracy and precision of the detection.

[0027] In specific operations, the staff can insert the device into the powdered material and detect the local humidity of the material through the contact humidity sensor. When the humidity in the material is abnormal, the vibration structure can be turned on to vibrate the material to promote the uniformity of the material in the sampling area. Then, the stepper motor drives the rotating ring 6 to rotate, and the sampling bin is opened for sampling. After sampling, the infrared detection device or the microwave detection device can simultaneously perform non-contact detection on the material in the sampling bin, thereby avoiding contamination or damage to the material. In addition, the contact humidity sensor can be put into the sampling bin for contact detection of the material, thereby improving the accuracy and precision of the detection.

[0028] This solution adopts a design of multiple sampling bins to facilitate multiple sampling and testing. At the same time, weighing sensors are installed in the sampling bins to monitor the quality changes of materials in real time, further improving the accuracy and precision of the detection.

[0029] After completing the inspection of all sampling bins, the inspection system will automatically analyze and process the inspection results, evaluate the material humidity, and display the results on the display screen. The staff can make corresponding operations and adjustments based on the inspection results to ensure the quality of the materials and the stability of production.

[0030] Second implementation method: Figure 5-6 It is shown that the detection method of the powder material humidity detection device includes: A1, insert the detection device into the powder material, and perform a preliminary detection of the material humidity through the contact humidity sensor on the detection column 11; A2, during the insertion process, the material humidity is preliminarily detected by the sensor at the top of the detection column 11. When abnormal material humidity is detected, sampling is performed for detection; A3, before sampling, the vibration structure 5 is turned on to vibrate the material near the sampling column 2 to promote uniform distribution of the material in the area near the sampling column 2; when sampling, the rotating ring 6 is then turned to open the sampling chamber, and the material enters the sampling chamber during the vibration process; When sampling the mixed material, the material with different particle sizes is screened through the filter 203. Through multiple samplings, the materials with different particle sizes are stored in multiple sampling bins respectively. When testing, the humidity of the multiple sampling bins is tested respectively. Finally, the test results of the multiple sampling bins are combined for data analysis. A4, after completing the sampling, the material type is identified through the image, and then the detection unit is set to prepare for the detection. Specifically, when the image recognizes the mixed material, multiple detection units can be set according to the identified powder types for multiple detections to ensure that each powder can be detected by a suitable detection unit; during the detection, the electric push rod is controlled to work, so that the detection unit set on the detection column 11 moves to the sampling bin at the corresponding position and performs humidity detection on the material. After the detection, the data is uploaded to the data storage module.

[0031] This embodiment performs accurate humidity detection on materials of different particle sizes in powder materials. Since materials of different particle sizes may exist in the mixed material, the humidity of these materials may be different. Therefore, during the sampling process, materials of different particle sizes can be stored in different sampling bins through the screening effect of the filter 203. In this way, the detection unit can perform humidity detection on multiple sampling bins respectively, so as to obtain more comprehensive and accurate humidity data.

[0032] In addition, this sampling method can also avoid cross contamination of materials during the sampling process. Since each sampling chamber is independent, materials of different particle sizes will not interfere with each other, thus ensuring the accuracy of the test results.

[0033] After sampling and testing, all humidity data will be uploaded to the data storage module. By analyzing these data, we can further understand the humidity distribution of powder materials and the humidity differences between materials of different particle sizes. These data can provide important references for subsequent production processes and help companies achieve more accurate and efficient material management.

[0034] This embodiment realizes accurate sampling and humidity detection of materials of different particle sizes in powder materials by adopting components such as contact humidity sensors, vibration structures, rotating rings and sampling bins, and facilitates the direct detection of mixed materials by extracting materials of different particle sizes for detection and analysis separately, so as to quickly analyze the humidity data of the mixed powder materials.

[0035] In summary, this solution facilitates sampling and testing through the sampling chamber after inserting the powder material, so as to facilitate multiple testing and particle size testing of the powder material, and facilitates the selection of different testing methods according to the powder type, and is easy to adapt to different types of powder material testing.

[0036] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
