Description

Technical Field

[0001] This utility model relates to the field of tobacco processing, and in particular to a tobacco shred circulation dryer. Background Technology

[0002] Tobacco drying is a crucial step in tobacco processing, as its moisture content and uniformity directly affect subsequent rolling quality, aroma release, and storage stability. Traditional drying methods have significant limitations: low automation, reliance on intermittent manual labor, inability to match continuous production rhythms, and low efficiency; uneven distribution of heating sources, leading to localized over-drying and scorching of tobacco or residual moisture affecting quality stability; lack of precise guidance during conveying, resulting in tobacco deviation and scattering, causing losses and uneven drying; insufficient precision in manual temperature control, resulting in large fluctuations in thermal parameters and poor consistency in moisture content, hindering the absorption of subsequent flavoring; and poor coordination between drying, conveying, and collection modules, leading to unstable quality and significant batch-to-batch differences, making it difficult to meet the stringent requirements of the tobacco industry for stable quality and efficient continuous production.

[0003] Therefore, those skilled in the art have provided a tobacco shred circulation dryer to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. This circulating tobacco dryer utilizes a multi-stage conveying device and control components to create a continuous drying process, overcoming the drawbacks of low efficiency and significant batch-to-batch quality variations in traditional drying methods. The inlet baffle, in conjunction with the inlet limiting plate, precisely guides the tobacco shreds into the conveying device, preventing them from shifting and scattering. Multiple sets of hot drying plates are evenly distributed along the conveying path within the chamber, creating a three-dimensional heating environment through continuous conveying, ensuring comprehensive heating of the tobacco shreds. This solves the problems of localized over-drying, scorching, or residual moisture in traditional drying methods, while also improving the looseness of the tobacco shreds and enhancing the absorption of subsequent flavoring. The power supply control box drives the conveying device to operate stably, and the first and second limiting plates ensure continuous conveying of the tobacco shreds without scattering or loss. The drying power supply control box precisely regulates the temperature of the hot drying plates, ensuring a stable and consistent moisture content, thus addressing the issue of insufficient precision in manual temperature control. The sealed collection chamber prevents moisture absorption, and the support legs stabilize the equipment. This device comprehensively improves the automation and uniformity of drying, reduces human intervention errors, ensures stable tobacco shred quality, and meets the high standardization requirements of tobacco processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tobacco shred circulation dryer includes a housing with an inner cavity. Four hot drying plates are fixedly installed within the inner cavity, each distributed along a tobacco shred conveying path. A drying power control box is fixedly installed at the back of the housing, and each hot drying plate is electrically connected to the drying power control box. A first conveying device, a second conveying device, and a third conveying device are installed within the inner cavity. A power supply control box is fixedly installed at the back of the housing, and the first, second, and third conveying devices are all electrically connected to the power supply control box. A feed inlet is located at the top of the housing. A first limiting plate and a second limiting plate are fixedly installed on the inner wall of the inner cavity near the end of the first and second conveying devices. A discharge outlet is located at the bottom of the housing, and a collection bin is fixedly installed at the bottom of the housing. A control panel is fixedly installed on the surface of the housing, and the control panel is electrically connected to the power supply control box and the drying power control box.

[0007] Through the above technical solution, four hot drying plates distributed along the tobacco conveying path are set in the inner cavity of the box, and together with the drying power control box electrically connected to the back, a precisely controllable stepped heating system is formed to achieve uniform heating of the tobacco throughout the entire conveying process. The first, second, and third conveying devices in the inner cavity of the box are driven by the power control box to construct a continuous path, solving the problem of discontinuous drying caused by traditional intermittent conveying. The feed inlet at the top of the box, together with the guiding action of the first and second limiting plates, ensures that the tobacco is transferred smoothly between the conveying devices, avoiding scattering and loss. The surface control panel is synchronously connected to the conveying and drying control box, realizing integrated control of drying temperature and conveying speed, simplifying the operation process. The discharge port at the bottom of the box cavity works in conjunction with the bottom collection bin to complete the centralized collection of dried tobacco shreds, forming an integrated closed-loop operation. This structure eliminates problems such as local overheating and moisture residue in traditional drying through the coordinated linkage of hot drying and conveying devices, improves drying uniformity, reduces human intervention errors through automated control, ensures stable and consistent moisture content of tobacco shreds, and solves the drawbacks of low efficiency and large batch quality differences in traditional drying, providing a highly efficient and stable tobacco drying solution for tobacco processing.

[0008] Furthermore, a feed inlet baffle is fixedly installed around the feed inlet, and a feed inlet limiting plate is fixedly installed inside the inner cavity of the box near the lower part of the feed inlet;

[0009] Through the above technical solution, the feed inlet baffle, which is fixed around the feed inlet, forms a protective structure that prevents the tobacco from scattering in all directions when it is fed in, thus avoiding waste of raw materials and contamination of the outside of the box. The feed inlet limiting plate, located in the inner cavity of the box near the bottom of the feed inlet, guides the falling tobacco neatly onto the first conveying device, preventing the tobacco from piling up or deviating from the conveying path, and ensuring uniform feeding. The two work together to optimize the feeding process, avoiding the problem of insufficient drying caused by the scattering and uneven distribution of tobacco during traditional feeding, ensuring the continuity of the conveying and drying process, and improving the utilization rate of raw materials and the stability of drying quality.

[0010] Furthermore, a discharge port limiting plate is fixedly installed inside the discharge port;

[0011] Through the above technical solution, the discharge port limiting plate fixedly installed inside the discharge port forms a guiding structure, which plays a role in regulating and guiding the tobacco shreds conveyed from the third conveying device to the discharge port, ensuring that the tobacco shreds fall smoothly into the bottom collection bin along the limiting path, reducing discharge residue and improving collection efficiency.

[0012] Furthermore, the collection chamber has an inner cavity, and a collection chamber cover is rotatably mounted on the top of the collection chamber;

[0013] Through the above technical solution, the inner cavity of the collection chamber forms a special space for holding tobacco shreds, providing a regular storage area for dried tobacco shreds and preventing tobacco shreds from scattering and mixing during the collection process. The collection chamber cover, which is rotatable on the top of the collection chamber, can be opened and closed flexibly. When closed, it can prevent external dust and impurities from entering the inner cavity and contaminating the tobacco shreds.

[0014] Furthermore, a support leg is fixedly installed at the bottom of the box, and an observation window is provided on the surface of the box;

[0015] The above technical solution forms a stable support structure by fixing support legs at the bottom of the box, which reliably supports the box and core components such as the internal hot drying plate and conveying device. The observation window on the surface of the box provides a visual monitoring channel, allowing operators to view the tobacco conveying status, hot drying effect and guide status of the limit plate in the internal cavity of the box in real time.

[0027] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides another specific embodiment:

[0028] A feed inlet baffle 2 is fixedly installed around the feed inlet 3, and a feed inlet limiting plate 18 is fixedly installed inside the inner cavity 10 near the lower part of the feed inlet 3. The feed inlet baffle 2 fixed around the feed inlet 3 forms a surrounding protective structure, which can prevent tobacco from scattering to the surroundings when it is fed in through the feed inlet 3, thus avoiding waste of raw materials and contamination of the outside of the box 1. The feed inlet limiting plate 18 near the lower part of the feed inlet 3 in the inner cavity 10 of the box plays a guiding role in the falling tobacco, guiding the tobacco neatly onto the first conveying device 16, and preventing the tobacco from falling out of the box. The material is piled up or deviates from the conveying path to ensure uniform feeding. The two work together to optimize the feeding process, avoiding the problem of insufficient drying caused by scattered and unevenly distributed tobacco shreds during traditional feeding. This ensures the continuity of the conveying and drying process, improves raw material utilization and drying quality stability. A fixed outlet limit plate 15 is installed inside the outlet 20, forming a guiding structure that regulates and guides the tobacco shreds conveyed from the third conveying device 14 to the outlet 20. To ensure that the tobacco shreds fall smoothly into the bottom collection chamber 8 along the limiting path, reducing material residue and improving collection efficiency, the collection chamber 8 has an inner cavity 7. The top of the collection chamber 8 is rotatably equipped with a collection chamber cover 6. The inner cavity 7 of the collection chamber 8 forms a dedicated space for tobacco shreds, providing a neat storage area for the dried tobacco shreds and preventing the tobacco shreds from scattering and mixing during the collection process. The rotatable collection chamber cover 6 on the top of the collection chamber 8 can be opened and closed flexibly. When closed, it can prevent external dust and impurities from entering the inner cavity 7 and contaminating the tobacco shreds. The bottom of the box body 1 is fixedly equipped with support legs 9, and the surface of the box body 1 is equipped with an observation window 11. By fixing the support legs 9 at the bottom of the box body 1, a stable support structure is formed, which reliably supports the box body 1 and the internal hot drying plate 17, conveying device and other core components. The observation window 11 on the surface of the box body 1 provides a visual monitoring channel. Operators can use the observation window 11 to view the tobacco shred conveying status in the inner cavity 10 of the box body, the drying effect of the hot drying plate 17 and the guiding status of the limiting plate in real time.

[0029] Working Principle: When the tobacco shreds circulating dryer is in operation, the operator sets the drying temperature and conveying speed via the control panel 21. The drying power control box 4 and the conveying power control box 5 start synchronously. The hot drying plate 17 is energized and preheated to the set temperature. The first conveying device 16, the second conveying device 12, and the third conveying device 14 operate in coordination. The bottom support legs 9 stably support the box body 1 and the entire equipment. The operator can monitor the operating status of the inner cavity 10 of the box in real time through the observation window 11. Tobacco shreds are fed in through the feed inlet 3. The feed inlet limit plate 18 controls the falling rhythm of the tobacco shreds to prevent them from piling up too quickly. The tobacco shreds are guided by the feed inlet limit plate 18 and fall onto the surface of the first conveying device 16. In the inner cavity 10 of the box, the first conveying device 16 carries and conveys the tobacco shreds. The square hot drying plate 17 releases heat to complete the initial drying. When the tobacco is conveyed to the end of the first conveying device 16, it is guided by the first limiting plate 19 to fall into the second conveying device 12 and continue to be deeply dried by the hot drying plate 17. When the tobacco moves to the end of the second conveying device 12, it is guided by the second limiting plate 13 to be transferred to the third conveying device 14. After being dried by the hot drying plate 17 at the bottom of the third conveying device 14, the final drying process is completed. After the third conveying device 14 conveys the tobacco to the end, it is guided by the discharge port limiting plate 15 in the discharge port 20 and falls accurately into the collection chamber cavity 7 of the collection chamber 8. After drying is completed, the dried tobacco can be taken out by opening the collection chamber cover 6. The whole process realizes continuous drying and collection of tobacco, ensuring drying uniformity and efficiency.
