Description

Technical Field

[0001] The invention relates to the technical field of tea moisture detection, and in particular to a moisture detection device and method based on tea processing. Background Art

[0002] The main function of the moisture detection equipment after tea drying is to accurately and in real time monitor the moisture content in tea to ensure the stability of tea quality and storage safety. Excessive moisture will cause mildew and deterioration, affecting the safety of tea; while too low moisture may affect the taste and aroma of tea. Moisture detection equipment can help manufacturers ensure that tea reaches the optimal moisture level by accurately controlling the drying process. From the structure and principle of the equipment, moisture detection equipment usually consists of sensors, control systems, display and alarm systems, and data processing modules. Sensors are the key part. Common types include capacitive sensors, infrared sensors, and microwave sensors, which determine moisture content by measuring physical properties such as capacitance, infrared light absorption, and microwave propagation. The control system outputs adjustment instructions based on the data from the sensor to ensure the optimization of the drying process. The display system displays the moisture content in real time and records historical data, and the alarm system issues an alarm when the moisture exceeds the standard;

[0003] For example, a moisture detection device for tea disclosed in the authorization announcement number CN221506595U includes a detection box, a partition is provided at the bottom of the detection box, a power connector is provided on one side of the partition, a shock absorbing module is provided on the other side of the partition, a rotating slot is provided on the shock absorbing module, a rotating motor is provided on the rotating slot, a rotating shaft is provided on the upper end of the rotating motor, a coupling is provided above the rotating shaft, a rotating connector is provided above the coupling, a weighing plate is provided above the rotating connector, and a drying dish is provided above the weighing plate. The tea leaves on the drying dish are dried by starting the dryer, and the rotating shaft is driven to rotate the rotating connector to drive the drying dish to rotate, so that the tea leaves are fully dried. After drying, the moisture content of the tea leaves is detected and fed back to the control panel in cooperation with the moisture detector. The existing moisture detection technology and equipment operation method are basically the same, all of which use the moisture detector to detect the tea leaves, but the tea samples detected are relatively small, that is, the dried tea materials are detected by local sampling. The moisture of the outer layer of the tea leaves is easier to evaporate than the moisture of the inner layer, and the moisture content of the outer layer of the tea leaves is relatively low, while the inner layer of the tea leaves may still maintain a high moisture content. This uneven moisture distribution causes different parts of the tea to have different moisture contents at the same time. As existing moisture detection technologies usually use local sampling methods, the measured moisture values ​​can only represent the moisture content of the tea sample and cannot truly reflect the moisture distribution of the entire batch of tea. More importantly, due to the high heat of the dried tea, the moisture inside the tea material may have been converted into water vapor. When sampling, the sample is exposed to room temperature, and part of the water vapor will re-condense into water, which will affect the measurement results, resulting in a high moisture value and unable to accurately reflect the moisture level of the entire batch of tea. Summary of the invention

[0004] The object of the present invention is to provide a moisture detection device and method based on tea processing, wherein the dried tea material is fed into a dual-zone storage box through a double-cavity material incoming channel, and a rotary drive unit is used to transmit power to a chain plate elevator and a primary double-side belt synchronous transmission structure. The primary double-side belt synchronous transmission structure enables the material transfer module in the dual-zone storage box and the driven air intake module above the dual-zone storage box to work, and the wind force generated by the driven air intake module enters the dual-zone storage box through a double-sided exhaust box, and with the cooperation of the material transfer module, the tea material in the storage box is quickly cooled and water vapor is released.

[0010] Preferably, a material blocking plug plate is installed inside the double-sided exhaust box on one side of the centrifugal fan outlet, and both ends of the material blocking plug plate pass through the interior of the double-sided exhaust box.

The external spline shaft slides along the center axis direction of the threaded shaft and is inserted into the internal spline transmission shaft. The threaded shaft is dynamically engaged with the crossbeam shaft through the external spline shaft, the internal spline transmission shaft, and the secondary double-side belt synchronous transmission structure.

[0014] Preferably, slot-shaped photoelectric switches for detecting the position of the slide plate are installed on both sides of the bottom end of the top plate.

[0015] Preferably, two parallel guide rails are installed on both sides of the bottom end of the top plate, and a slide table that slidably cooperates with the guide rails is installed on the top end of the slide plate.

[0016] The present invention also provides a method for detecting moisture based on tea processing, such as the above-mentioned device for detecting moisture based on tea processing, comprising the following steps:

[0017] S101: The staff needs to check the working status of each module to ensure that all modules are operating normally, check whether the feeding of the double-cavity incoming channel is smooth, whether the double-zone storage box is normally distributed, whether the chain plate elevator is running smoothly, etc., and ensure that each module is in normal working condition before continuing with subsequent operations. The staff pours the tea material into the double-cavity incoming channel, and the double-cavity incoming channel ensures that the material flows smoothly into the double-zone storage box, and inserts the material blocking plug into the double-sided exhaust box, and uses the material blocking plug to block the material in the upward lifting direction of the chain plate elevator to prevent the tea material from being sent out by the chain plate elevator;

[0018] S102: Start the rotary drive unit, and the rotary power of the rotary drive unit is transmitted to the chain plate elevator and the first-level double-side belt synchronous transmission structure respectively, while the inner spline drive shaft and the second-level double-side belt synchronous transmission structure enable the two driven air inlet modules to maintain power connection, and the airflow generated by the driven air inlet module enters the two chambers of the dual-zone storage box through the double-sided exhaust box. At this time, the double-sided exhaust box and the driven air inlet module cool and dehumidify the tea material through the function of sweeping the airflow. During the dehumidification process, the material shifting module synchronously receives part of the rotary power from the first-level double-side belt synchronous transmission structure, which is responsible for quantitatively shifting and turning the tea material to avoid the phenomenon of uneven distribution of moisture in the outer layer and the inner layer of the material caused by the tea material in the dual-zone storage box being in a piled state;

[0019] S103: After the temperature is lowered, the staff makes the mobile dual-zone moisture detection module and the inner spline transmission shaft engage with each other, and the inner spline transmission shaft makes the mobile dual-zone moisture detection module work, and the mobile dual-zone moisture detection module makes the detector move in the length extension direction of the dual-zone storage box, and uses the detector to detect the moisture of the tea leaves in the dual-zone storage box, and uses the horizontal movement method to perform a comprehensive detection of the tea materials in the dual-zone storage box to ensure the effective detection range;

[0020] S104: Finally, the staff needs to continuously monitor the output results of the mobile dual-zone moisture detection module and adjust the production plan in a timely manner according to the moisture situation.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the moisture detection equipment and method based on tea processing deliver the dried tea material into the dual-zone storage box through the dual-cavity incoming material channel, and use the rotary drive unit to transmit power to the chain plate elevator and the primary double-side belt synchronous transmission structure, so that the tea material is quickly cooled and water vapor is released, and finally the tea material is tested for moisture through the mobile dual-zone moisture detection module, wherein the dried tea material is delivered into the dual-zone storage box, and the driven air intake module is used to cool the tea material and discharge water vapor, so that the moisture detection can be performed more evenly and after cooling, reducing the interference of water vapor on the detection result, and through the precise scanning of the mobile dual-zone moisture detection module, the entire material can be tested for moisture more comprehensively, which can not only cover the entire material batch, but also effectively avoid the error of local samples, thereby improving the accuracy and representativeness of moisture detection;

[0022] In addition, the tea material after drying is often at a high temperature and has a large water content, which causes the water vapor to evaporate quickly during moisture detection. The wind force generated by the driven air inlet module and the double-sided exhaust box can help the water vapor to be discharged, reducing the impact of internal water vapor on moisture detection. That is, after the tea material is cooled, the moisture content is more stable, and the test results are closer to the actual moisture level.

[0023] In addition, the use of a mobile moisture detection module can achieve continuous monitoring of the entire batch of tea materials without frequently interrupting the production line, avoiding the production bottleneck in traditional detection methods. By combining with the automation system, moisture detection can be carried out in real time, helping the production line to adjust the drying temperature and time in real time, thereby achieving more accurate drying control, ensuring the quality of tea while improving production efficiency.

The staff can adhere a layer of gauze on the front and rear outer walls of the double-sided exhaust box 6 to prevent the tea leaves in the double-zone storage box 2 from entering the double-sided exhaust box 6 by using the gauze;

[0041] A top plate 8 is fixed on the top of the main frame 1 between the two driven air inlet modules 10, an inner spline transmission shaft 9 is rotatably mounted on the outer wall of one side of the top plate 8 close to the double-cavity material inlet channel 5, a secondary double-side belt synchronous transmission structure 11 for driving the two driven air inlet modules 10 to work synchronously is mounted on the end of the inner spline transmission shaft 9 away from the top plate 8, and a mobile dual-zone moisture detection module 15 for power engagement with the inner spline transmission shaft 9 and detecting the moisture content of the tea material in the dual-zone storage box 2 is mounted on the bottom end of the top plate 8;

[0042] The material shifting module 14 is arranged in the inner chamber of the dual-zone material storage box 2. A primary double-side belt synchronous transmission structure 13 for maintaining power transmission is installed between the driven air inlet module 10, the material shifting module 14 and the chain plate elevator 4 in the same X-axis extension direction. A rotary drive unit 12 for driving the chain plate elevator 4 is installed on one side of the main frame 1;

[0043] The chain plate elevator 4 lifts the material to the required position along the conveying path through the cooperation of the chain and the plate chain. In the device, the chain plate elevator 4 lifts the tea material on the one hand, and on the other hand, the material blocking plug plate 7 blocks the tea in the lifting process and returns it to the double-zone storage box 2, so that the tea material is in an active state; when the material is to be discharged, the staff will take out the material blocking plug plate 7 from the double-sided exhaust box 6, so that the chain plate elevator 4 can send the tea material out of the double-zone storage box 2, which can continuously and stably transport a large amount of tea, avoiding the inconvenience and instability caused by manual handling;

[0044] The rotary drive unit 12 is composed of a reduction motor 1201, a main shaft 1202 and a bevel gear transmission structure 1203. The main shaft 1202 is rotatably installed at the bottom of the main frame 1 through a bearing seat. The extension direction of the main shaft 1202 is parallel to the length extension direction of the dual-zone storage box 2. The bevel gear transmission structure 1203 is installed at one end of the main shaft 1202 and is used to be interconnected with the input shaft of the chain plate elevator 4. The reduction motor 1201 is arranged on one side of the main frame 1, and the output shaft of the reduction motor 1201 is fixedly connected to the other end of the main shaft 1202 through a coupling. The main shaft 1202 drives the material transfer module 14 and the driven air intake module 10 to work through a primary double-side belt synchronous transmission structure 13. When the rotary drive unit 12 is working, the rotational power of the reduction motor 1201 is transmitted to the chain plate elevator 4 and the first-level double-side belt synchronous transmission structure 13 and the material feeding module 14 through the main shaft 1202 and the bevel gear transmission structure 1203. The reduction motor 1201 can transmit power efficiently and stably to ensure the efficient operation of all parts of the entire equipment. At the same time, by adjusting the speed of the reduction motor 1201, the movement speed and direction of each part of the equipment can be accurately controlled to ensure smooth connection of each link; the staff can add a motor controller to the outer wall of one side of the main frame 1, use the motor controller and the reduction motor 1201 for electrical connection, and control the speed and direction of the reduction motor 1201.

[0045] A method for detecting moisture in tea leaves based on tea processing according to this embodiment, such as the above-mentioned device for detecting moisture in tea leaves based on tea processing, comprises the following steps:

[0046] S101: The staff needs to check the working status of each module to ensure that all modules are operating normally, check whether the double-chamber incoming channel 5 is feeding smoothly, whether the double-zone storage box 2 is distributed normally, whether the chain plate elevator 4 is running smoothly, etc., and ensure that each module is in normal working condition before continuing with subsequent operations. The staff pours the tea material into the double-chamber incoming channel 5, and the double-chamber incoming channel 5 ensures that the material flows into the double-zone storage box 2 smoothly, and inserts the material blocking plug plate 7 into the double-sided exhaust box 6, and uses the material blocking plug plate 7 to block the material in the upward lifting direction of the chain plate elevator 4 to prevent the tea material from being sent out by the chain plate elevator 4;

[0047] S102: Start the rotary drive unit 12, and the rotary power of the rotary drive unit 12 is transmitted to the chain plate elevator 4 and the first-level double-side belt synchronous transmission structure 13 respectively, while the inner spline transmission shaft 9 and the second-level double-side belt synchronous transmission structure 11 make the two driven air inlet modules 10 maintain power connection, and the airflow generated by the driven air inlet module 10 enters the two chambers of the dual-zone storage box 2 through the double-sided exhaust box 6. At this time, the double-sided exhaust box 6 and the driven air inlet module 10 cool and dehumidify the tea material through the function of sweeping the airflow. During the dehumidification process, the material shifting module 14 synchronously receives part of the rotary power from the first-level double-side belt synchronous transmission structure 13, which is responsible for quantitatively shifting and turning the tea material to avoid the phenomenon of uneven distribution of moisture in the outer layer and the inner layer of the material caused by the tea material in the dual-zone storage box 2 being in a piled state;

[0048] S103: After the temperature is lowered, the staff makes the mobile dual-zone moisture detection module 15 and the inner spline transmission shaft 9 perform power engagement, and the inner spline transmission shaft 9 makes the mobile dual-zone moisture detection module 15 work, and the mobile dual-zone moisture detection module 15 makes the detector move in the length extension direction of the dual-zone storage box 2, and uses the detector to detect the moisture of the tea leaves in the dual-zone storage box 2, and uses the horizontal movement method to perform a comprehensive detection of the tea leaves in the dual-zone storage box 2 to ensure the effective detection range;

[0049] S104: Finally, the staff needs to continuously monitor the output results of the mobile dual-zone moisture detection module 15 and adjust the production plan in a timely manner according to the moisture situation.

[0050] Embodiment 2, based on embodiment 1, Figure 7 and Figure 8It is given that the driven air inlet module 10 includes a beam shaft 1002 rotatably mounted on one side of the top of the main frame 1 through a bearing seat and a centrifugal fan 1001 mounted on the outer wall of one side of the main frame 1, the air outlet of the centrifugal fan 1001 extends to the inside of the double-sided exhaust box 6, the extension direction of the central axis of the beam shaft 1002 is parallel to the extension direction of the central axis of the main shaft 1202, one end of the beam shaft 1002 is fixedly connected to the input shaft of the centrifugal fan 1001, and a material blocking plug plate 7 is installed inside the double-sided exhaust box 6 on one side of the air outlet of the centrifugal fan 1001, and both ends of the material blocking plug plate 7 pass through the inside of the double-sided exhaust box 6;

[0051] When the primary double-side belt synchronous transmission structure 13 transmits power to the driven air intake module 10, the primary double-side belt synchronous transmission structure 13 drives the crossbeam shaft 1002 to rotate, and the crossbeam shaft 1002 drives the input shaft of the centrifugal fan 1001 to rotate, and makes the centrifugal fan 1001 work. At this time, the centrifugal fan 1001 provides a suitable air flow to the double-sided exhaust box 6, and the generated air flow continues to enter the dual-zone storage box 2 through the double-sided exhaust box 6, and the tea material is cooled down, reducing the water vapor content inside the tea; the internal spline transmission shaft 9 and the secondary double-side belt synchronous transmission structure 11 enable the crossbeam shafts 1002 in the two driven air intake modules 10 to be dynamically engaged.

[0052] Embodiment 3, based on embodiment 2, Fig. 9 and Fig.10 It is given that the material-diverting module 14 includes a main rotating shaft 1401 rotatably mounted on the inner wall of one side of the dual-zone material storage box 2 and a plurality of three-leaf material-diverting racks 1402 fixed at one end of the surface of the main rotating shaft 1401. The extension line of the central axis of the main rotating shaft 1401 is parallel to the extension line of the central axis of the crossbeam shaft 1002. A bracket 101 for supporting the dual-cavity incoming channel 5 is provided on one side of the main frame 1. The tea material is put into the dual-cavity incoming channel 5. The middle partition inside the dual-cavity incoming channel 5 allows the material to be diverted and enter the chambers of the dual-zone material storage box 2 where the material-diverting module 14 is located respectively.

[0053] The primary double-side belt synchronous transmission structure 13 includes a first driving transmission structure 1301 installed between the main shaft 1202 and the same end of the main rotating shaft 1401, and a second driving transmission structure 1302 installed between the same end of the main rotating shaft 1401 and the crossbeam shaft 1002;

[0054] The main shaft 1202 drives the main rotating shaft 1401 in the material shifting module 14 to rotate through the first driving transmission structure 1301, and the main rotating shaft 1401 drives the centrifugal fan 1001 to rotate through the second driving transmission structure 1302. At this time, the main rotating shaft 1401 continuously shifts the tea material in the dual-zone storage box 2 through the three-leaf material shifting rack 1402. The material shifting mechanism can avoid the generation of water vapor caused by excessive accumulation of materials, thereby reducing the moisture detection error caused by uneven distribution of materials, and the moisture detection is more accurate; at the same time, after the material is shifted, the airflow generated by the double-sided exhaust box 6 and the driven air inlet module 10 can more easily contact the tea material and cause it to cool down.

[0055] Embodiment 4, based on embodiment 3, Fig.11 , Fig.12 , Fig.13 and Fig.14 It is given that the mobile dual-zone moisture detection module 15 includes a threaded shaft 1501 rotatably mounted on one side of the bottom end of the top plate 8 through a bearing seat, a nut pair 1502 mounted at a threaded portion on one end of the surface of the threaded shaft 1501, a slide plate 1503 slidably mounted on the top end of the top plate 8, and a moisture tester 1504 mounted on both sides of the bottom end of the slide plate 1503. The bottom end of the nut pair 1502 is fixedly connected to the top end of the slide plate 1503, and an external spline shaft 1505 is slidably plugged into one end of the threaded shaft 1501 close to the internal spline transmission shaft 9. The external spline shaft 1505 slides along the central axis direction of the threaded shaft 1501 and is plugged into the internal spline transmission shaft 9. The threaded shaft 1501 is dynamically engaged with the crossbeam shaft 1002 through the external spline shaft 1505, the internal spline transmission shaft 9, and the secondary double-side belt synchronous transmission structure 11.

[0056] When using the mobile dual-zone moisture detection module 15 to detect the moisture content of tea leaves in the dual-zone storage box 2, the staff turns on the two moisture testers 1504, manually removes the outer spline shaft 1505 from the threaded shaft 1501, and plugs the outer spline shaft 1505 with the inner spline transmission shaft 9. At this time, the rotary power of the secondary double-side belt synchronous transmission structure 11 and the inner spline transmission shaft 9 is transmitted to the threaded shaft 1501 through the outer spline shaft 1505, and the threaded shaft 1501 drives the nut pair 1502 and the slide plate 1503 to slide, that is, the two moisture testers 1504 are all moved in the chamber of the dual-zone storage box 2. At this time, the moisture tester 1504 can detect the moisture content of materials in different areas of the dual-zone storage box 2. By adjusting the position of the moisture tester 1504, it is ensured that it can pass through different detection areas evenly to ensure more accurate moisture measurement;

[0057] Two parallel guide rails are installed on both sides of the bottom end of the top plate 8, and a slide table that slides with the guide rails is installed on the top of the slide plate 1503. Slot-type photoelectric switches 1506 for detecting the position of the slide plate 1503 are installed on both sides of the bottom end of the top plate 8. During the movement of the slide plate 1503, the slot-type photoelectric switches 1506 on both sides of the bottom end of the top plate 8 are used to detect the moving position of the slide plate 1503 to obtain the moving position of the moisture tester 1504 in the dual-zone storage box 2.

[0058] When the embodiment of the present application is in use, the staff first needs to check the working status of each module to ensure that all modules are operating normally, check whether the dual-chamber incoming channel 5 feeds smoothly, whether the dual-zone storage box 2 is distributed normally, whether the chain plate elevator 4 operates smoothly, etc., and only after ensuring that each module is in normal working condition can the subsequent operations be continued. The staff pours the tea material into the dual-chamber incoming channel 5. Through the dual-chamber design of the incoming channel, it is ensured that the material can be quickly and evenly diverted to the two storage chambers of the dual-zone storage box 2. During this process, the staff needs to observe the material distribution to ensure that the process of material flowing into the dual-zone storage box 2 is smooth to avoid blockage or unevenness. If there is any abnormality, the channel setting needs to be adjusted in time to avoid affecting the smooth flow of subsequent processes. The staff inserts the material blocking plug plate 7 into the double-sided exhaust box 6, and uses the material blocking plug plate 7 to block the material in the upward lifting direction of the chain plate elevator 4 to prevent the tea material from being sent out by the chain plate elevator 4. Then the staff needs to start the rotary drive unit 12, and the rotary power of the rotary drive unit 12 is transmitted to the chain plate elevator 4 and the first-level double-side belt synchronous transmission structure 13 respectively. The chain plate elevator 4 lifts the material from the dual-zone storage box 2 and is blocked by the material blocking plug plate 7 and moves down again, thereby ensuring that there is no accumulation of tea material or too slow flow rate. In this process, the internal spline transmission shaft 9 and the second-level double-side belt synchronous transmission structure 11 keep the power connection between the two driven air inlet modules 10, and the two driven air inlet modules 10 both receive the power from the rotary drive shaft 9 and the second-level double-side belt synchronous transmission structure 11. The driving unit 12 and a part of the rotational power of the first-level double-side belt synchronous transmission structure 13, the wind speed of the driven air intake module 10 is proportional to the rotation speed of the rotating driving unit 12, and then the airflow generated by the driven air intake module 10 enters the two chambers of the dual-zone storage box 2 through the double-sided exhaust box 6. At this time, the double-sided exhaust box 6 and the driven air intake module 10 cool and dehumidify the tea material through the function of sweeping the airflow, and maintain the humidity control of the material. In the process of cooling and dehumidifying the tea leaves in the dual-zone storage box 2 by the double-sided exhaust box 6 and the driven air intake module 10, the material shifting module 14 synchronously receives part of the rotational power from the first-level double-side belt synchronous transmission structure 13, which is responsible for quantitatively shifting and turning the tea leaves, so as to avoid the tea leaves in the dual-zone storage box 2 from being The uneven distribution of moisture in the outer and inner layers of the materials caused by the materials being in a stacked state. After the cooling is completed, the staff makes the mobile dual-zone moisture detection module 15 and the inner spline transmission shaft 9 dynamically connected, and the inner spline transmission shaft 9 makes the mobile dual-zone moisture detection module 15 work. The mobile dual-zone moisture detection module 15 makes the detector move in the length extension direction of the dual-zone storage box 2, and uses the detector to detect the moisture of the tea leaves in the dual-zone storage box 2. The tea leaves in the dual-zone storage box 2 are fully detected by horizontal movement to ensure the effective detection range. Finally, the staff needs to continuously monitor the output results of the mobile dual-zone moisture detection module 15, and adjust the production plan in time according to the moisture situation.If the moisture content exceeds the standard or is unqualified, it may be necessary to adjust the tea processing process or perform secondary drying to ensure that the tea eventually meets the standard. When the material in the dual-zone storage box 2 needs to be discharged, the staff will remove the material blocking plate 7 from the double-sided exhaust box 6 and release the power connection between the mobile dual-zone moisture detection module 15 and the internal spline transmission shaft 9. Then the chain plate elevator 4 will send the tea material in the dual-zone storage box 2 out for the staff to carry out the next step of processing.
