Description

Technical Field

[0001] This invention relates to the field of feed pellet moisture sensor detection technology, specifically to a rapid feed pellet moisture detection device. Background Technology

[0002] Feed pellets generally contain a certain proportion of moisture after pelleting. Appropriate moisture content allows starch to gelatinize fully during pelleting, resulting in firm pellets and reducing powdering. However, excessively high or low moisture content can affect the quality and safety of the feed pellets. Therefore, it is necessary to test the moisture content of the feed pellets after pelleting to ensure pellet quality and durability while preventing mold growth and protecting the health and safety of the animals that consume them.

[0003] In existing technologies, when rapidly detecting the moisture content of a small amount of feed pellets in the laboratory, a detection method based on the principle of thermogravimetric analysis is generally adopted. Typically, a representative small amount of feed pellets is first spread flat in a container, and then the container is placed on a weighing instrument equipped with a heating device. The feed pellet sample is then heated and dried by the heating device to promote moisture evaporation. At the same time, the mass change of the feed pellet sample is continuously monitored in real time by the weighing instrument. Finally, by calculating the mass difference of the feed pellet sample before and after heating, the proportion of moisture lost by evaporation in the feed pellets can be quickly estimated.

[0004] However, traditional laboratory methods for rapid detection of moisture content in feed pellets using the weight loss method have the following problems: 1. In existing technologies, when feed pellets are dried using a heating device, a small amount of volatile oils, flavor substances, and low-boiling-point organic components such as alcohols in the feed pellets easily evaporate with the water vapor. After heating, these residues condense and adhere to the inner wall of the chamber and the surface of the container. Furthermore, these residues accumulate, easily causing cross-contamination of other feed pellet samples being tested and continuously participating in or interfering with subsequent changes in feed pellet quality, thus gradually negatively impacting the accuracy of the measurement results; 2. In existing technologies, due to the unavoidable collisions during transport or processing, the feed pellet samples to be tested typically contain particles of varying sizes. Different types of feed pellets exist, with smaller pellets having a larger surface area per unit mass. Under the same heating conditions, their moisture evaporation rate is significantly faster than that of larger pellets, allowing them to reach complete dryness first. However, the uniform heating and drying process continues at this point, causing the smaller pellets to enter an over-drying stage. This not only leads to the complete evaporation of moisture from the smaller pellets but also to the further evaporation and loss of volatile oils, flavor compounds, alcohols, and other organic components. Consequently, more non-moisture substances are included in the total weight loss, further increasing the impact on the accuracy of the final calculated moisture ratio. Furthermore, it increases the content of volatile organic compounds condensing and adhering to the inside of the instrument, accelerating the continuous accumulation of volatile organic compounds and increasing the risk of cross-contamination of subsequent feed pellet samples.

[0012] Preferably, the movable docking part includes a U-shaped docking frame with the telescopic end of the electric push rod and two guide rods fixedly installed on the left side and the opening facing backward.

[0013] Preferably, the screening support includes an adjustment plate rotatably disposed inside the U-shaped docking frame. The adjustment plate is slidably disposed with a support vessel that moves up and down and has a plurality of vertically penetrating sieve holes evenly opened at the bottom. The rear end of the adjustment plate is symmetrically fixed with rotating shafts that are rotatably connected to the U-shaped docking frame, wherein a rectangular slot is opened on the left side of the left rotating shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, through the cooperation of the detection mechanism, the carrying mechanism and the cleaning mechanism, can realize the rapid shaking and sorting of feed pellet samples with mixed particle sizes during the initial feeding, so as to significantly reduce the particle size difference of the feed pellets to be tested. In addition, the shaking promotes the uniform spreading of feed pellets that meet the particle size requirements in the carrying container, which not only ensures the heating efficiency and uniformity of the feed pellet detection process, but also significantly reduces the drying difference between feed pellets. It ensures that all feed pellets evaporate moisture as synchronously as possible under the same heating environment, thereby effectively inhibiting further pyrolysis loss of volatile organic substances, reducing the impact of non-moisture loss on weighing, improving the accuracy of moisture content estimation, and also reducing the release of volatile substances from the source, reducing the condensation and accumulation of volatile organic substances inside the instrument, and improving the reliability and consistency of subsequent feed pellet moisture detection.

[0019] 2. Through the cooperation of the detection mechanism, the carrying mechanism, and the cleaning mechanism, this invention can also achieve timely removal of uncondensed volatile substances in the carrying chamber by hot air blowing from bottom to top after the sample measurement is completed. This effectively prevents volatile substances from adhering to the inside of the carrying chamber. During the feeding of feed pellets, the carrying container is quickly wiped, thereby physically removing trace amounts of residue that may have adhered to the surface of the carrying container during the measurement. This avoids the continuous accumulation of volatile substances and cross-contamination of subsequent pellets to be measured, allowing the instrument to remain more stable in the initial calibration state, thereby improving the accuracy, consistency, and reliability of the overall moisture measurement results of feed pellets.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 A rapid moisture detection device for feed pellets includes a base plate 1, on the left and right sides of the upper side of the base plate 1, a cleaning mechanism 4 and a detection mechanism 2, and a bearing mechanism 3 is provided on the detection mechanism 2.

[0033] Please see Figure 1 The detection mechanism 2 includes a docking weighing part 21 disposed on the upper side of the base plate 1 for real-time detection of the weight of feed pellet samples. The docking weighing part 21 is provided with a heating and drying part 22 for heating and drying samples and a drive adjustment part 23.

[0034] Please see Figure 1 , Figure 2 and Figure 4 The docking weighing unit 21 includes a control console 211 fixedly installed on the upper side of the base plate 1. The front side of the control console 211 is provided with a control screen for inputting operation commands, reading weighing values ​​and displaying the calculated moisture content. The upper side of the control console 211 is fixedly provided with a weighing platform 212 with an inclined outer surface and a gravity sensor inside. The upper right side of the control console 211 is fixedly provided with a splicing sealing plate 213.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The heating and drying unit 22 includes a shielding platform 221 fixedly installed on the upper side of the rear end of the control console 211. A heating cover 222 is hinged to the upper side of the shielding platform 221. The heating cover 222 is equipped with a halogen heating lamp for rapid heating of the sample and a temperature sensor for real-time monitoring of the sample temperature. A handle is fixedly installed on the upper side of the heating cover 222.

[0036] Operation commands can be input to the heating cover 222 via the control panel on the console 211. The heating cover 222 controls the heating and drying of the feed pellet sample loaded in the carrier mechanism 3 using a halogen heating lamp. The temperature of the feed pellet sample is monitored in real time by a temperature sensor to prevent excessive volatilization of organic matter due to excessively high pellet temperature. At the same time, the mass change of the feed pellet sample is accurately detected synchronously by the weighing platform 212. The relevant values ​​for calculating the moisture content of the feed pellets, such as the detected pellet mass value, temperature change value, and the final automatically obtained moisture content estimate value, can all be directly read from the control panel.

[0037] Please see Figure 1 , Figure 2 and Figure 4 The drive adjustment unit 23 includes an L-shaped bracket 231 fixedly installed on the right side of the control console 211. An electric push rod 232 is fixedly installed on the right side of the vertical section of the L-shaped bracket 231. A guide rod 233 that moves left and right is symmetrically installed on the vertical section of the L-shaped bracket 231 and on the front and rear sides of the electric push rod 232.

[0038] Please see Figure 1 The carrying mechanism 3 includes a movable docking part 31 disposed on the drive adjustment part 23 and adjusted left and right in coordination with the drive adjustment part 23, and a screening carrying part 32 disposed on the movable docking part 31 for carrying and screening feed pellet samples.

[0039] Please see Figure 1 , Figure 4 and Figure 5 The movable docking part 31 includes a U-shaped docking frame 311 with the telescopic end of the electric push rod 232 and two guide rods 233 fixedly arranged on the left side and the opening facing backward. The right side of the U-shaped docking frame 311 has a clearance groove 312 that runs through the left and right sides and is inserted into the splicing sealing plate 213. A support strip 313 is fixedly arranged on the inner side of the front end of the U-shaped docking frame 311.

[0040] Please see Figure 1 , Figure 6 and Figure 8 The screening support 32 includes an adjustment plate 321 rotatably disposed inside the U-shaped docking frame 311. The lower front side of the adjustment plate 321 is stably attached to the upper surface of the support strip 313, and the front end of the adjustment plate 321 cannot continue to rotate downward under the restriction of the support strip 313. The adjustment plate 321 is slidably disposed with a support vessel 322 that moves up and down and has a plurality of vertically penetrating sieve holes evenly opened at the bottom. The rear end of the adjustment plate 321 is symmetrically fixed with a rotating shaft 323 that is rotatably connected to the U-shaped docking frame 311. A rectangular slot 324 is opened on the left side of the left rotating shaft 323.

[0041] When moisture testing is performed on feed pellets that meet the particle size requirements after sieving in the carrier 322, the electric actuator 232 first moves the U-shaped docking frame 311 to the right. The weighing platform 212 then passes through the clearance groove 312 and contacts the lower right side of the carrier 322. The carrier 322 then gradually slides upward along the adjusting plate 321 by engaging with the outer inclined surface of the weighing platform 212 until the clearance groove 312 is fully engaged with the splicing sealing plate 213. This allows the moisture content of the feed pellets to be measured via the control console 211, the shielding platform 221, the heating cover 222, and the U-shaped docking frame 311. The splicing sealing plate 213 stably surrounds the carrier 322 within the enclosed heating space. At this time, the weighing platform 212 stably supports the carrier 322 and the feed particles inside. Meanwhile, the adjusting plate 321 no longer supports the carrier 322 and the feed particles, so that the weighing platform 212 can accurately measure the initial weight of the feed particles inside the carrier 322. Then, the feed particles are heated and dried by the heating cover 222, and the weighing platform 212 measures the dehydrated weight of the feed particles after drying, thereby calculating the moisture ratio in the feed particles.

[0042] When completing the moisture test of feed pellets, the electric actuator 232 first moves the U-shaped docking frame 311 and the carrier container 322 to the left to the cleaning mechanism 4 to ensure that the internal temperature of the U-shaped docking frame 311 and the carrier container 322 does not drop rapidly, thereby preventing volatile substances from condensing and adhering quickly. This allows the cleaning mechanism 4 to promptly disperse and clean the volatile substances inside the U-shaped docking frame 311 and the carrier container 322. Then, the heating cover 222 is flipped backward so that the high-temperature volatile substances remaining on the lower side of the heating cover 222 can also quickly dissipate, thereby preventing the accumulation and residue of volatile substances.

[0043] Please see Figure 1 The cleaning mechanism 4 includes a guide feeding section 41 disposed on the upper side of the base plate 1. The guide feeding section 41 is used to guide the smaller particles screened out and the dried particles after testing. A docking screening section 42 is disposed on the left side of the guide feeding section 41 to flip and shake the screening support section 32. A hot air blowing section 43 is disposed at the front end of the guide feeding section 41 to blow hot air from bottom to top to sweep away volatile substances in the support mechanism 3. An inner wall cleaning section 44 is disposed at the rear end of the guide feeding section 41 to wipe and clean the residual volatile substances in the screening support section 32.

[0044] Please see Figure 1 , Figure 7 and Figure 8 The guide unloading part 41 includes a guide platform 411 fixedly installed on the upper side of the base plate 1 with inclined surfaces at both the front and rear ends. A first baffle 412 is symmetrically fixedly installed on the left and right sides of the guide platform 411, and a second baffle 413 is fixedly installed on the upper side of the first baffle 412 and on the rear side of the U-shaped docking frame 311.

[0045] Please see Figure 1 , Figure 6 , Figure 7 and Figure 9 The docking screening section 42 includes an L-shaped bracket 421 fixedly installed on the left side of the left side baffle 412. A rotary cylinder 422 is fixedly installed on the left side of the vertical section of the L-shaped bracket 421. A connecting shaft 423 is fixedly installed at the drive end of the rotary cylinder 422. A rectangular insert 424 that is inserted into the rectangular slot 324 is fixedly installed on the right side of the connecting shaft 423.

[0046] When the electric actuator 232 moves the U-shaped docking frame 311 and the adjusting plate 321 to the left, the adjusting plate 321 moves the rotating shaft 323 synchronously. The rectangular slot 324 on the left rotating shaft 323, which is aligned with the rectangular insertion post 424, moves synchronously until the rectangular slot 324 docks with the rectangular insertion post 424 and the rectangular insertion post 424 is fully inserted into the rectangular slot 324. At this time, the U-shaped docking frame 311 moves the carrier vessel 322 to the front inclined surface of the guide table 411. The rotating cylinder 422 can drive the connecting shaft 423 and the rectangular insertion post 424 to rotate in a specific direction. The rectangular insertion post 424 then drives the left rotating shaft 323 to rotate synchronously. The left rotating shaft 323 then drives the adjusting plate 321 and the carrier vessel 322 to rotate and adjust synchronously around the rotating shaft 323.

[0047] When the feed pellet sample to be tested is fed into the carrier 322 located above the guide table 411 by manual operation or conveying equipment, the rectangular insert 424 and the left rotating shaft 323 are first driven by the rotating cylinder 422 to swing back and forth at a small angle. This causes the adjusting plate 321 to drive the carrier 322 to swing back and forth up and down around the rotating shaft 323 at a small angle. The carrier 322 then shakes and screens the feed pellet sample it carries, so that the smaller particles pass through the sieve holes and fall down onto the front inclined surface of the guide table 411. Under the guidance of the front inclined surface of the guide table 411, they slide forward for easy collection. Meanwhile, the particles that meet the particle size requirements in the carrier 322 can be gradually and evenly spread in the carrier 322 under the action of continuous shaking.

[0048] The above-described operation method enables rapid shaking and sorting of feed pellet samples with mixed particle sizes during the initial feeding stage, significantly reducing the particle size difference of the feed pellets to be tested. Simultaneously, the shaking promotes the uniform spreading of feed pellets meeting the particle size requirements in the carrier container 322. This ensures heating efficiency and uniformity during feed pellet testing, significantly reduces drying differences between feed pellets, and ensures that all feed pellets evaporate moisture as synchronously as possible under the same heating environment. This effectively inhibits further pyrolysis loss of volatile organic compounds, reduces the impact of non-moisture loss on weighing, and improves the accuracy of moisture content estimation. Furthermore, by reducing the release of volatile substances at the source, it reduces the condensation and accumulation of volatile organic compounds inside the instrument, improving the reliability and consistency of subsequent feed pellet moisture detection.

[0049] Please see Figure 1 , Figure 7 and Figure 8 The hot air purging unit 43 includes a mounting plate 431 with two baffles 412 fixedly installed at their front ends. Multiple purging pipes 432 are evenly fixedly installed on the mounting plate 431 from left to right. Each purging pipe 432 consists of a bent pipe with its rear end bent upward and a straight pipe with its front end connected to an external hot air blower (not shown in the figure).

[0050] Please see Figure 7 , Figure 8 and Figure 10 The inner wall cleaning section 44 includes two baffles 412 and a through groove that is opened together at the rear end of the guide table 411 and runs through the left and right sides. A rotary cylinder 441 is fixedly installed in the through groove. A connecting shaft 442 that runs through the guide table 411 from top to bottom is fixedly installed at the driving end of the rotary cylinder 441. A cleaning brush 443 is fixedly installed on the upper side of the connecting shaft 442 through a connecting plate.

[0051] When the tested feed pellets are promptly pushed onto the guide platform 411 by the carrier 322, hot air is continuously supplied to the purge pipe 432 by an external hot air blower. The curved pipe at the rear end of the purge pipe 432 then guides the hot air to the carrier 322. At the same time, the rotating cylinder 422 causes the carrier 322 and the feed pellets to rotate and shake synchronously at a small angle, so that the hot air passes stably through the sieve holes of the carrier 322 and continuously purges the internal space of the carrier 322 and the U-shaped docking frame 311, thereby quickly dispersing the volatile substances that have not condensed inside the carrier 322 and the U-shaped docking frame 311.

[0052] After being swept by hot air for a certain period of time, the adjusting plate 321 and the carrier 322 are rotated 180 degrees backward by the rotating cylinder 422. The dried feed particles in the carrier 322 then fall downward onto the inclined surface behind the guide table 411. Guided by the inclined surface behind the guide table 411 and blocked by the baffle 413, they slide steadily backward for easy collection. At this time, the cleaning brush 443 enters the carrier 322, which has been rotated 180 degrees, and presses firmly against the inner wall of the carrier 322. Then, the rotating cylinder 441 drives the connecting shaft 442 and the cleaning brush 443 on the upper part of the connecting plate to rotate and wipe continuously. The cleaning brush 443 quickly cleans the trace amounts of volatile substances remaining on the inner wall of the carrier 322. After cleaning, the adjusting plate 321 and the carrier 322 are rotated forward again by the rotating cylinder 422 to return to the initial state.

[0053] The above operating method enables the rapid removal of uncondensed volatile substances from the carrier chamber by hot air blowing from bottom to top after sample measurement, effectively preventing volatile substances from adhering to the inside of the carrier chamber. During the feeding of feed pellets, the carrier container 322 is quickly wiped, thereby physically removing trace amounts of residue that may have adhered to the surface of the carrier container 322 during this measurement. This avoids the continuous accumulation of volatile substances and cross-contamination of subsequent pellets, allowing the instrument to remain more stable in the initial calibration state, thereby improving the accuracy, consistency, and reliability of the overall moisture measurement results of feed pellets.

[0054] It should be noted that in existing technologies, the carrier container 322 can be manually cleaned after cooling. Although this is technically easier and simpler to operate, it only solves the problem of the impact of condensed volatile substances on the surface of the carrier container 322 on subsequent feed particle testing. This existing technology still faces problems such as over-drying of small-diameter feed particles, further increase in volatile organic compounds affecting the accuracy of moisture measurement, and cross-contamination of feed particle samples when heating and drying feed particles of different sizes and dealing with condensed volatile substances in the entire heating chamber. However, in the present invention, the hot air purging unit 43 can promptly purge and disperse uncondensed volatile substances, effectively avoiding condensed volatile organic compound residues, and... The screening section 42, in conjunction with the screening support section 32, screens feed particles of different sizes, avoiding inconsistent drying processes and significantly reducing the interference of volatile organic compounds on moisture measurement. Furthermore, compared to existing laboratory feed particle moisture measurement equipment, this solution adds a cleaning mechanism 4 and other mechanical structures, all of which are conventional and ordinary mechanical components without any high-cost precision parts. The investment is only required once for long-term use, making the cost of adding these structures low. Compared to significantly improving the accuracy, consistency, and reliability of overall moisture measurement of feed particle samples, the cost of adding these structures is negligible. In summary, the above-mentioned technical solution of this invention is a specific improvement based entirely on the existing technology and aimed at solving the technical problems.
