Apparatus for identifying freshness of sea cucumber and method thereof

Abstract

This invention relates to the technical field of sea cucumber freshness detection equipment, specifically a device for identifying the freshness of sea cucumbers. It includes a halogen moisture analyzer, which has an internal leveling mechanism and a locking mechanism on its side. The leveling mechanism also has a weighing structure inside, with a support structure on top and a weighing pan on top of the support structure. This invention uses the weight of the counterweight mechanism, lower flange, and vertical legs to apply a rotational force to the inner ring, allowing it to rotate around the center of the ball within the outer ring until the central axis of the inner ring is vertical. When rotation stops, the central axes of the weighing structure, support structure, and adjustment mechanism are vertical. The locking mechanism locks the inclined platform, fixing the vertical state of the weighing structure, support structure, and adjustment mechanism, thus achieving the purpose of leveling the support structure. The weight of the sea cucumber tissue inside the weighing pan acts vertically on the weighing sensor, resulting in more accurate weighing data.

Description

Technical Field

[0001] This invention relates to the technical field of sea cucumber freshness detection equipment, specifically to a device and method for identifying the freshness of sea cucumbers. Background Technology

[0002] Sea cucumber, a prized seafood tonic, is rich in protein, polysaccharides, saponins, and other nutrients. Its high nutritional and edible value makes it highly sought after in domestic and international markets. The freshness of sea cucumber directly determines its quality grade, safety, and market value. Insufficient freshness not only leads to nutrient loss but also poses a risk of food safety issues due to the accumulation of harmful substances caused by microbial growth. Therefore, accurate detection of sea cucumber freshness is crucial in the processing, distribution, and consumption of seafood. Among various freshness testing methods, moisture content is the core indicator for judging sea cucumber freshness. High-quality dried sea cucumber typically has a moisture content of ≤15%. Excessive moisture easily leads to dampness, mold, spoilage, and decay. Halogen moisture analyzers, with their advantages of high heating efficiency, fast detection speed, and relatively simple operation, have become the mainstream equipment for detecting sea cucumber moisture content. They measure the weight difference of the sample before and after heating using the pyrolysis gravimetric method, quickly calculating the moisture percentage and providing data support for determining sea cucumber freshness.

[0003] Existing halogen moisture analyzers used for detecting the freshness of sea cucumbers are typically placed on a table. Due to the levelness of the table and the presence of debris, it is difficult to ensure that the halogen moisture analyzer is placed horizontally. Tilting the equipment can cause uneven force on the weighing sensor, resulting in greater deviations in the moisture measurement values ​​and failing to accurately reflect the true freshness of the sea cucumbers. Furthermore, manual calibration with standard weights is required, and these weights are prone to loss or contamination. Non-professional users find it difficult to master the calibration process. In addition, sea cucumber sample debris, salt crystals, and other impurities can easily remain in the weighing area, making cleaning difficult. These residual impurities can interfere with the accuracy of subsequent tests. Therefore, there is an urgent need to design a device for identifying the freshness of sea cucumbers. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for identifying the freshness of sea cucumbers, in order to solve the problems mentioned in the background art. Existing halogen moisture analyzers for detecting the freshness of sea cucumbers are typically placed on a table, which is affected by the table's levelness and debris, making it difficult to ensure the analyzer is placed horizontally. Tilting the device can lead to uneven force on the weighing sensor, resulting in increased deviations in moisture measurements and an inability to accurately reflect the true freshness of the sea cucumbers. Furthermore, manual calibration with standard weights is required, and these weights are easily lost or contaminated. Non-professional users find the calibration process difficult to master. Additionally, sea cucumber sample debris and salt crystals easily remain in the weighing area, making cleaning difficult, and residual impurities can interfere with the accuracy of subsequent tests.

S3: Use the touchscreen to start the detection process until the device makes contact.

[0015] The beneficial effects that can be achieved by the above embodiments of the present invention include: 1. This invention applies a flipping force to the inner ring using the weight of the counterweight mechanism, lower flange, and vertical legs, allowing the inner ring to rotate around the center of the ball within the outer ring until the central axis of the inner ring is vertical. The counterweight mechanism links and fixes the adjusting mechanism, weighing structure, support structure, and lower flange, ensuring that the central axes of the weighing structure, support structure, and adjusting mechanism are vertical when the inner ring stops rotating. The locking mechanism locks the inclined platform, fixing the vertical state of the weighing structure, support structure, and adjusting mechanism, thus achieving the purpose of leveling the support structure. The weight of the sea cucumber tissue inside the weighing pan acts vertically on the weighing sensor, resulting in more accurate weighing data. It eliminates measurement errors caused by unevenness of the tabletop without manual adjustment, and the measurement results more accurately reflect the true situation, improving the practicality and applicability of this device for identifying the freshness of sea cucumbers.

[0016] 2. This invention separates the counterweight body from the adjustment mechanism by adjusting the contraction of the adjustment mechanism. At this time, the counterweight body is suspended on the end plate through the cap and the shaft hole. The weight of the cap, the threaded column and the counterweight body acts on the weighing sensor through the end plate, the long rod and the top plate for calibration. There is no need to carry additional calibration weights, which effectively avoids the loss and contamination of weights. Calibration can be completed with one click, reducing the threshold for non-professional users.

[0017] 3. This invention assembles the bracket through the snap-fit ​​action between the fastener and the slot, making it easy for people to remove the bracket to clean foreign objects on the partition. The rubber column is inserted into the damping groove with an interference fit, and the friction between the rubber column and the damping groove is used to fix the inner column, making the bracket more stable and the weighing more accurate. A spherical groove is opened on the end face of the rubber block away from the guide piston. In the natural state, the diameter of the spherical groove is equal to the diameter of the spherical diameter on the outer side of the inner ring. This ensures that the inner ring will not deflect when the rubber block is pressed against the inner ring, increasing the leveling accuracy. Attached Figure Description

[0024] Please see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The leveling mechanism 2 includes an outer ring 201, with an upper flange 202 fixedly connected to the top of the outer ring 201. The upper flange 202 is bolted to the bottom surface of the partition plate 107. The outer ring 201 and the circular hole 108 share a central axis. An inner ring 203 is movably fitted inside the outer ring 201. The inner and outer sides of the outer ring 201 and the inner ring 203 are both spherical, and the centers of all the spheres coincide.

A through hole 207 is opened in the middle of the positioning plate 206, and the weighing structure 4 is inserted into the through hole 207.

[0025] Since the outer ring 201 and the inner ring 203 are both spherical and their centers coincide, the inner ring 203 can rotate freely around the center of the sphere.

[0026] Please see Figure 7 There are four locking mechanisms 3, which are evenly distributed along the circumference on the outer side of the outer ring 201. Each locking mechanism 3 includes a base 301, which is fixedly connected to the outer side of the outer ring 201. An insertion hole 302 is provided inside the base 301, and the central axis of the insertion hole 302 passes through the center of the sphere. A first telescopic rod 303 is bolted to the end face of the base 301 away from the outer ring 201. The first telescopic rod 303 is inserted into the insertion hole 302. A guide piston 304 is fixedly connected to one end of the first telescopic rod 303 located inside the insertion hole 302. A rubber block 305 is fixedly installed on the end face of the guide piston 304 away from the first telescopic rod 303. The end face of the rubber block 305 away from the guide piston 304 abuts against the surface of the inner ring 203. A spherical groove is provided on the end face of the rubber block 305 away from the guide piston 304. In its natural state, the diameter of the spherical groove is equal to the diameter of the sphere on the outer side of the inner ring 203.

[0027] Please see Figure 5 , Figure 6 , Figure 9 and Figure 10 The weighing structure 4 includes a fixed column 401, which is inserted into the through hole 207. The fixed column 401 is coaxial with the through hole 207. A base plate 402 is fixedly connected to the top of the fixed column 401. A weighing sensor 403 is fixedly installed on the base plate 402. A top plate 404 is fixedly installed on the top of the weighing sensor 403. A bracket structure 5 is installed on the top surface of the top plate 404.

[0028] Please see Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11 and Figure 12The support structure 5 includes an outer tube 501, which is fixedly connected to the top surface of the top plate 404. The outer tube 501 is coaxial with the top plate 404 and is inserted into the circular hole 108. An inner column 502 is movably inserted inside the outer tube 501. A bracket 503 is fixedly installed on the top surface of the inner column 502. The weighing pan 109 is placed on the bracket 503. The tail end of the bracket 503 is bent upward to guide the weighing pan 109 symmetrically, so that the weighing pan 109 is accurately aligned. An annular groove 504 is opened on the side of the inner column 502. Slots 505 are correspondingly opened on the upper and lower surfaces of the inner cavity of the annular groove 504. 5. An internally movable fastener 506 is provided. The fastener 506 consists of a V-shaped part in the middle and two straight parts at its two ends. The straight parts are movably inserted into the slot 505. The inner wall of the outer tube 501 has a fastening groove 507. The V-shaped part is inserted into the fastening groove 507. The bottom center of the inner column 502 has a damping groove. The center of the top surface of the top plate 404 has a screw hole 508. The outer tube 501 has a rubber column 509 inside. The rubber column 509 has a bolt hole 510 inside. The bolt hole 510 has a bolt inside. The bolt passes through the bolt hole 510 and is threaded into the screw hole 508.

[0029] The V-shaped part of the fastener 506 engages with the buckle groove 507, and combined with the friction between the rubber column 509 and the damping groove of the inner column 502, it fixes the position of the bracket 503 and the weighing pan 109, ensuring that there is no displacement during the testing process.

[0030] Pull the bracket 503 directly upwards. The inner wall of the groove 507 applies pressure to the V-shaped part of the fastener 506. The V-shaped part opens under force and retracts into the annular groove 504. Then, the whole consisting of the inner column 502 and the bracket 503 is disassembled. The V-shaped part elastically recovers so that the residue on the partition 107 can be cleaned. After cleaning, insert the inner column 502 into the outer tube 501. The V-shaped part is pressured by the inner wall of the outer tube 501 and retracts into the annular groove 504. When the V-shaped part is aligned with the annular groove 504, the V-shaped part elastically recovers and extends into the groove 507, which plays a locking role.

[0031] Please see Figure 5 , Figure 6 , Figure 8 ,and Figure 9There are four calibration counterweights 6, which are evenly distributed on the bottom surface of the top plate 404. Each calibration counterweight 6 includes a long rod 601, which is fixedly connected to the bottom surface of the top plate 404. A small hole is opened on the positioning plate 206. The bottom end of the long rod 601 passes through the small hole and is fixedly connected to an end plate 602. A cap 603 is provided on the outside of the long rod 601. A threaded post 604 is fixedly connected to the bottom surface of the cap 603. A central hole 605 is opened at the central axis of the cap 603 and the threaded post 604.

During calibration, the adjusting mechanism 7 shortens, and the cap 603, threaded column 604, and counterweight body 606 are suspended and exert force on the end plate 602. When not calibrating, the adjusting mechanism 7 extends, and the cap 603, threaded column 604, and counterweight body 606 are clamped between the positioning plate 206 and the linkage ring 708. At this time, the cap 603, threaded column 604, and counterweight body 606 do not exert force on the end plate 602.

[0033] Please see Figure 5 , Figure 6 ,and Figure 13 The adjustment mechanism 7 includes a support base plate 701, which is fixedly connected to the bottom end of the fixed column 401. The support base plate 701 and the fixed column 401 are coaxial. A support leg 702 is fixedly connected to the bottom edge of the support base plate 701. A mounting flange 703 is fixedly connected to the bottom end of the support leg 702. A counterweight mechanism 8 is installed on the bottom surface of the mounting flange 703.

A linkage column 706 is fixedly connected to the top edge of the linkage plate 705. A guide hole 707 is opened on the top edge of the support base plate 701. The top end of the linkage column 706 passes through the guide hole 707 and is fixedly connected to a linkage ring 708. The top surface of the linkage ring 708 supports the counterweight body 606 through the bottom surface of the counterweight body 606.

The balance block is symmetrical about the central axis of the counterweight plate 801 and the distance detector 802. The weight of the balance block and the distance detector 802 are equal.

[0035] A method for determining the freshness of sea cucumbers includes the following steps: S1: Place the device used to identify the freshness of sea cucumbers on the table, then open the flip cover 105, then remove the weighing pan 109, and then use the touch screen 104 to start automatic calibration and complete the calibration work. S2: Put the weighing pan 109 back in its original position, then add sea cucumber tissue inside the weighing pan 109, and then close the flip cover 105. S3: Use the touchscreen 104 to start the detection process until the detection is made.

[0036] Working principle Automatic leveling: After placing the device on the table, the weight of the counterweight mechanism 8, lower flange 205, and vertical leg 204 applies a flipping force to the inner ring 203. Since the outer ring 201 and the inner ring 203 are both spherical with their centers coinciding, the inner ring 203 can freely rotate around the center of the sphere until its central axis is vertical. At this point, the weighing structure 4, support structure 5, calibration counterweight 6, adjustment mechanism 7, and counterweight mechanism 8 are all in a vertical position. Then, the first telescopic rod 303 is controlled using the touch screen 104. The first telescopic rod 303 extends and pushes the guide piston 304 and the rubber block 305 to tightly abut against the surface of the inner ring 203. The spherical groove of the rubber block 305 and the outer spherical surface of the inner ring 203 are used to lock the vertical state of the inner ring 203, thereby fixing the vertical state of the weighing structure 4, the support structure 5, the calibration counterweight 6, and the adjustment mechanism 7, ensuring that the weight of the sea cucumber tissue in the weighing pan 109 acts vertically on the weighing sensor 403, eliminating weighing errors caused by factors such as uneven tabletops and debris. During calibration: The touch screen 104 is used to start the calibration mode. The touch screen 104 controls the second telescopic rod 704 to shorten. Then, the second telescopic rod 704 moves downward synchronously with the linkage plate 705, linkage column 706, and linkage ring 708. Then, the linkage ring 708 loses contact with the bottom surface of the counterweight body 606. After the counterweight body 606 loses support, it is suspended on the end plate 602 through the threaded column 604 and the cap 603. At this time, the weight of the cap 603, threaded column 604, and counterweight body 606 is transmitted to the top plate 404 through the end plate 602 and the long rod 601 and acts on the weighing sensor 403. The weighing sensor 403 collects the weight data and compares it with the built-in standard value of the touch screen 104 to automatically correct the weighing deviation and complete the calibration. After calibration, the touch screen 104 controls the extension of the second telescopic rod 704. Then, the second telescopic rod 704 drives the linkage plate 705, linkage column 706, and linkage ring 708 to move upward synchronously. Next, the linkage ring 708 supports the entire structure consisting of the counterweight body 606, cap 603, and threaded column 604 to move upward. Then, the top surface of the cap 603 abuts against the bottom surface of the positioning plate 206, and the top surface of the linkage ring 708 abuts against the bottom surface of the counterweight body 606. At this time, the entire structure consisting of the counterweight body 606, cap 603, and threaded column 604 is clamped between the positioning plate 206 and the linkage ring 708. The end plate 602 is suspended in the column groove. The counterweight body 606, cap 603, and threaded column 604 do not apply any force to the end plate 602 to avoid the counterweight body 606, cap 603, and threaded column 604 interfering with normal weighing. During testing: The sea cucumber tissue is laid flat in the weighing pan 109, and then the weighing pan 109 is precisely placed on top of the inner column 502 by the guidance of the bracket 503. The flip cover integration 105 is closed, and the halogen lamp integrated inside the flip cover integration 105 starts heating. The fan accelerates the air circulation inside the outer shell 101, and the temperature sensor monitors the temperature inside the heating chamber in real time to maintain a stable drying environment, so that the moisture in the sea cucumber tissue in the weighing pan 109 evaporates quickly. The weighing sensor 403 collects the weight data of the weighing pan 109 and the sea cucumber tissue in real time, and the touch screen 104 records the initial weight and the real-time weight change during the drying process. When the weight change meets the set conditions, the touch screen 104 automatically calculates the moisture content and displays the test results, thus completing the identification of the freshness of the sea cucumber.
