Description

[0002] Natural spices are substances with fragrance extracted directly from plants or animals in nature by physical methods.

Natural spices are widely used in high-end perfumes, cosmetics and food fields due to their rich fragrance levels and natural softness. Pepper is one of the most widely used cooking spices, and it is not only a historical trade commodity but also an important medicinal plant. In order to maintain the rich aroma and pungent flavor of pepper, a special conveying device is used to transport the pepper to the corresponding processing equipment to complete the subsequent powdering or particle packaging process.

[0003] At present, pepper still faces some problems in the production and transportation process. When transporting pepper to the subsequent processing link, a closed screw conveyor is usually used for transportation. However, the transfer speed is slow, and it is easily limited by factors such as the flowability of pepper particles and the conveying angle, which limits the conveying amount per unit time. This not only reduces the upper limit of the speed of the entire production line, but also causes low processing efficiency. In addition, during the transportation process, the pepper needs to be sent to low-temperature fumigation and rolling screen separation equipment, which causes the material to be transferred between devices, resulting in waiting and start-stop phenomena, which not only prolongs the total processing time, but also makes it difficult to realize flexible adjustment and efficient linkage of the process flow.

[0027] 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.

[0028] Please see Figure 1 , Figure 2 and Figure 4 A transport device for the production of natural spices includes a conveying pipe 1 fixedly installed on a storage silo, a screening chamber 2 fixedly installed at the left end of the conveying pipe 1, a central shaft 4 rotatably installed through the screening chamber 2, a plurality of screen plates 5 fixedly sleeved on the central shaft 4 located inside the screening chamber 2, and a discharge pipe 6 fixedly installed on the screening chamber 2 located between adjacent screen plates 5.

[0029] Both the conveying pipe 1 and the discharge pipe 6 are equipped with several annular gas pipes 3. The annular gas pipes 3 inject carbon dioxide gas into the conveying pipe 1 and the discharge pipe 6 through the No. 1 gas valve 31 for transporting pepper.

[0030] The screening chamber 2 is equipped with several No. 2 gas valves 32 that inject carbon dioxide gas into it and cooperate with the sieve plate 5 to screen the size of pepper particles. The carbon dioxide gas introduced into the screening chamber 2 and the conveying pipe 1 is used to treat the pepper for pest control.

[0031] It should be noted that the conveying pipeline 1 designed in the scheme can be directly connected with the storage bin loaded with pepper, and can also be sealingly connected with the discharge end of the screw conveyor. Optionally, butterfly valves (not shown in the figure) can be arranged at the left end and the right end of the conveying pipeline 1 to increase the sealing performance of the conveying pipeline 1 and the screening bin 2. The opening degree and duration of the first air valve 31 and the second air valve 32 can be controlled by a preset program or sensor feedback to control the gas flow and form auxiliary screening.

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a plurality of first air valves 31 are fixedly installed in a circumferential array on the ring-shaped air pipe 3, and the first air valves 31 are fixedly penetrated through the outer ring wall of the conveying pipeline 1 or the discharge pipe 6, respectively. A plurality of first air valves 31 on the same ring-shaped air pipe 3 on the conveying pipeline 1 are all deflected to the left side.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 4 , the screen holes on the plurality of screen plates 5 in the screening bin 2 decrease in diameter from right to left, and the space between the adjacent screen plates 5 decreases from right to left. The second air valve 32 is fixedly penetrated and installed on the outer ring wall of the screening bin 2 and located between the adjacent screen plates 5.

[0034] In specific work, when the pepper enters the conveying pipeline 1, the circumferentially arrayed first air valves 31 receive carbon dioxide gas through the connecting air pipe 33 and spray into the pipeline interior at uniform intervals. Thus, the carbon dioxide gas in the conveying pipeline 1 forms a pneumatic conveying power to rapidly push the pepper into the screening bin 2. Among them, the uniform distribution of carbon dioxide gas in the conveying pipeline 1 ensures that the gas directly acts on the conveying path of the pepper particles, avoiding material accumulation caused by uneven local gas distribution.

[0035] When the pepper particles enter the screening bin 2, they first contact the screen plate 5 with the largest aperture on the right side. The large particles that do not pass through are intercepted in the right area, while the particles that pass through the screen holes enter the next screening interval. As the material moves to the left, the screen hole diameter gradually decreases, and the particles are classified in turn according to medium and fine particle size. The decreasing distance between adjacent screen plates 5 gradually reduces the material accumulation height during the screening process, preventing fine particles from being covered by large particle layers.

[0036] The second air valve 32 independently injects carbon dioxide gas into each screening interval, and the airflow forms an acceleration effect in the tapered screen plate 5 spacing. Each screening interval forms an independent gas circulation path, avoiding interference of different particle size levels of materials by cross airflow. In addition, the carbon dioxide gas forms a laminar flow in the tapered screen plate 5 spacing, so that the gas penetrates the pepper gap to the maximum extent, and the fumigation and pest control are achieved by concentration maintenance, so that the gas medium is reused in the transportation and screening links.

[0037] Therefore, high-concentration and high-flow-rate carbon dioxide is used to assist in the transportation of peppers, and the peppers are screened and treated for pests under the action of the carbon dioxide airflow. High-concentration carbon dioxide can rapidly replace oxygen in the environment, causing pests to die of asphyxiation in a short time, thereby avoiding the residual risk and environmental problems that may be caused by chemical fumigants. In addition, the airflow can effectively penetrate the pepper particle layer, ensuring that there are no dead angles in the treatment process. The entire treatment process is carried out in an inert environment filled with carbon dioxide, effectively isolating oxygen and greatly inhibiting the oxidation of volatile aromatic substances in the peppers and the attenuation of flavor, so that the three key processes of material transportation, screening, and biological control are continuously completed in a closed system, significantly shortening the total processing time of the peppers and greatly improving the production capacity.

[0038] Please refer to Figure 4 and Figure 5 , the center shaft rod 4 is provided with a spoiler 41, the spoiler 41 includes a plurality of support pipes 412 fixedly installed in a circumferential array manner at the right end of the center shaft rod 4, the center shaft rod 4 is internally provided with an air passage in communication with the plurality of support pipes 412, and the plurality of support pipes 412 are fixedly installed with a support ring 411 away from the center shaft rod 4, the support ring 411 is fixedly installed with a third air valve 413 corresponding to and in communication with the support pipe 412, and the connecting pipe is fixedly installed with a connecting pipe penetrating the center shaft rod 4, and the connecting pipe and the air passage are in communication.

[0039] Please refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 , the screen plate 5 is provided with a scraping part 51 and a residue discharge part 52, the screen plate 5 is provided with an electrostatic adsorption layer, the left end face of the screening bin 2 is fixedly installed with a first motor 42 through a motor bracket, the output end of the first motor 42 is drivingly connected with the center shaft rod 4 through a gear set, and the center shaft rod 4 rotates the screen plate 5 to scrape the impurities adsorbed on the screen plate 5 through the scraping part 51.

[0040] Specifically, when the carbon dioxide gas enters the ventilation channel of the central shaft 4 through the connecting pipe, it is transported to the support ring 411 along the support pipe 412, and the first motor 42 rotates the central shaft 4 through the gear set, and the support ring 411 drives the third air valve 413 to perform circumferential motion, so that the gas forms a rotating jet flow through the third air valve 413.

[0041] The opening degree and duration of the third air valve 413 can be controlled by a preset program or sensor feedback to control the gas flow, so that the opening degree of each third air valve 413 can be adjusted according to the thickness of the pepper stack, for example, when it is detected that the pepper layer in a certain area is thicker, the opening of the corresponding third air valve 413 can be increased to enhance the gas flow impact, and the rotating motion of the support ring 411 diffuses the gas along the radial direction through centrifugal effect. Through the above technical solutions, the turbulent effect of the rotating jet flow can scatter the pepper particle agglomerates, and the separation accuracy of the sieve plate 5 for particle size is improved.

[0042] Please refer to Figure 4 、 Figure 6 、 Figure 7 and Figure 8 , the scraping part 51 includes a positioning ring 511 fixedly installed on the inner ring wall of the screening bin 2 and corresponding to the sieve plate 5, a recess is formed in the inner ring wall of the positioning ring 511 for limiting the rotation of the sieve plate 5, and a scraping plate 512 symmetrically arranged left and right with respect to the sieve plate 5 is fixedly installed at the lower end of the positioning ring 511. A slag discharge port 514 is formed in the lower end of the positioning ring 511 and penetrates the inner ring wall of the positioning ring 511 and the outer ring wall of the screening bin 2, and a collection box 513 corresponding to the slag discharge port 514 is fixedly installed on the outer ring wall of the screening bin 2.

[0043] Please refer to Figure 6 and Figure 9 , the slag discharge part 52 includes arc-shaped cover plates 523 symmetrically arranged left and right above the slag discharge port 514, a limiting slide 521 is formed in the slag discharge port 514 of the positioning ring 511, a sliding block 522 is slidingly installed in the limiting slide 521 through the spring, and the sliding block 522 is fixedly connected with the arc-shaped cover plates 523 symmetrically arranged left and right through the triangular plates arranged thereon. A rubber rod 524 is fixedly installed on the front side of the upper end surface of the arc-shaped cover plate 523, and a push rod in contact with the rubber rod 524 is fixedly installed on the sieve plate 5.

[0044] Specifically, after the screening of the pepper is completed, the first air valve 31, the second air valve 32 and the third air valve 413 are closed, at this time the sieve plate 5 continues to rotate with the central shaft 4, the electrostatic adsorption layer of the sieve plate 5 actively captures the light impurities such as hair and fibers mixed in the pepper, and the symmetrically distributed scraping plates 512 scrape the surface of the sieve plate 5 in both directions during the rotation of the sieve plate 5, and peel off stubborn impurities adhered to the edge of the sieve hole.

[0045] When the screen plate 5 rotates to drive the push rod to contact the rubber rod 524, the rubber rod 524 drives the left and right arc-shaped cover plates 523 to expand synchronously to open the residue discharge port 514, and the scraped impurities fall into the collection box 513 through the residue discharge port 514 under the action of the centrifugal force, and when the push rod is separated from the rubber rod 524, the spring pushes the sliding block 522 to reset, drives the arc-shaped cover plate 523 to close to form a seal, and realizes periodic automatic residue discharge.

[0046] The arc-shaped cover plate 523 of the residue discharge port 514 is kept closed under the action of the spring, and only opens the residue discharge port when the push rod is triggered, so that the screening operation and the self-cleaning process are synchronized, forming a continuous screening and cleaning cycle, solving the problem of impurities blocking the screen holes in the pepper screening process, and improving the screening efficiency.

[0047] Please refer to Figure 1 and Figure 2 , the screening bin 2 and the discharge pipe 6 are provided with a discharging part 61 and a driving part 62 for sealing the screening bin 2 or controlling the discharging, and the same number of air valves 31 on the same annular air pipe 3 on the discharge pipe 6 are all deflected forward.

[0048] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , the discharging part 61 includes a discharging port 611 penetratingly arranged on the inner ring wall of the screening bin 2 and corresponding to the discharge pipe 6, the outer ring wall of the screening bin 2 is provided with a sealing plate 612 corresponding to the discharging port 611, the sealing plate 612 is fixedly installed with left and right symmetrical support rotating rings 613, the support rotating rings 613 are rotatably installed on the outer ring wall of the screening bin 2, and the support rotating rings 613 are fixedly installed with a connecting rod 614 therebetween.

[0049] Please refer to Figure 2 and Figure 4 , the driving part 62 includes a second motor 621 fixedly installed on the outer ring wall of the screening bin 2 through a motor bracket, and the support rotating ring 613 is provided with an incomplete tooth, and the output end of the second motor 621 is fixedly sleeved with a gear meshed with the incomplete tooth.

[0050] In specific work, after the classification of the pepper particles in the screening bin 2 is completed, the second motor 621 is started, the gear and the incomplete tooth are matched, the support rotating ring 613 is driven to rotate by a certain angle, the connecting rod 614 drives the sealing plate 612 to open or close the discharging port 611. At this time, the classified pepper particles can be conveyed outward through the discharge pipe 6. In the sealing stage, the sealing plate 612 completely covers the discharging port 611 to prevent material leakage during the screening process, and the edge of the sealing plate 612 forms a surface contact seal with the outer wall of the screening bin 2 to prevent carbon dioxide gas leakage.

[0051] The discharge port 611 corresponds to each discharge pipe 6 to ensure that the pepper particles of different particle sizes can pass through the corresponding discharge port 611 into the designated pipe after being screened. The first air valve 31 is deflected forward, so that the carbon dioxide gas flow pushes the pepper particles to accelerate forward movement, thereby being discharged through the discharge pipe 6. In this way, the pepper particles of different particle sizes can be batch-oriented discharged to the corresponding processing station, avoiding cross-contamination and efficiency loss in the material transfer process.
