Description

Technical Field

[0001] This utility model relates to the field of star anise production technology, specifically a high-efficiency and flexible star anise drying production line. Background Technology

[0002] As a key spice, the drying quality of star anise directly determines its flavor retention and storage stability. Currently, the industry still mainly uses traditional natural sun-drying and equipment-based drying methods for star anise. Firstly, natural sun-drying typically involves drying in open areas or greenhouses, relying on sunlight and natural air circulation. This method heavily depends on sunny, dry weather and usually takes 7-10 days to reach the ideal dryness level, requiring a long time and a large space, which is not conducive to large-scale production. However, star anise achieves relatively good and uniform moisture content (because it is laid flat to dry). Secondly, using drying equipment followed by a three-dimensional turning and drying machine allows for rapid drying of star anise, suitable for industrial production. However, existing drying equipment in factories is mostly fixed-installation, with non-adjustable platform height, making it unsuitable for loading and unloading devices of different heights. Furthermore, the equipment is heavy and lacks easily movable parts, limiting its operation to a fixed location and making it difficult to flexibly adjust its position according to the production process or connect with the turning and drying machine. Its poor adaptability and the use of only a single heating method result in low heating efficiency and delayed moisture removal, further affecting the drying quality. Therefore, how to flexibly adjust the star anise drying mode by fully combining weather conditions and production tasks to improve the drying quality of star anise has always been a research and exploration area in the industry in order to solve the problems raised in the background technology. Utility Model Content

[0006] Furthermore, multiple sets of dehumidifying fans for ventilation are fixedly connected to the outer wall of the drying housing.

[0007] Furthermore, a caster wheel for movement is fixedly connected to the lower surface of the connecting base.

[0008] Furthermore, a first plate and a second plate are fixedly connected to the surface of the stand. The second plate is located on the side closer to the drying shell, and the height of the first plate is greater than the height of the second plate.

[0009] Furthermore, a protective cover is fixedly connected to the side wall of the platform, and a first synchronous pulley and a second synchronous pulley are rotatably connected to the inner side wall of the protective cover. A timing belt is provided between the first synchronous pulley and the second synchronous pulley, and one end of the second synchronous pulley is fixedly connected to the end of the conveyor roller shaft.

[0010] Furthermore, a servo motor is fixedly connected to the lower surface of the platform, and the power output end of the servo motor is fixedly connected to the shaft end of the first synchronous pulley.

[0012] Furthermore, the drying conveyor belt is connected to the feeder via a parallel conveyor belt.

[0013] Furthermore, there are two parallel conveyor belts, which are perpendicular to the feeder and set on both sides of the feeder's inlet end.

[0014] Furthermore, a drying conveyor belt is also connected to the discharge end of the three-dimensional turning and drying machine.

Detailed Implementation

[0018] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1:

[0019] Please see Figure 1A high-efficiency flexible production line for drying star anise includes a feeder 2A that feeds star anise material to a three-dimensional turning and drying machine 3A. A drying conveyor belt 1A is connected to the feeder 2A via a parallel conveyor belt 5A. There are two parallel conveyor belts 5A, which are set perpendicular to the feeder 2A on both sides of the feeder 2A's inlet end. The above equipment is all existing equipment. The three-dimensional turning and drying machine 3A generally adopts a multi-layer structure. The conveyor chain drives the conveyor net to move, so that the star anise material is dried on different layers of net, such as the Chinese invention patent "A Three-Dimensional Rice Turning and Drying Equipment for Agriculture" (CN108278873B). The 8-layer turning and drying machine used in this embodiment has a material spreading area of ​​1365㎡ and a turning and drying cycle that is adjustable from 3 to 30 hours. When the weather is good and the temperature is high, the turning and drying effect is better. At this time, the turning and drying cycle can be shortened and the turning and drying machine can move faster, thus increasing the feed volume. At this time, the number of drying conveyor belts 1A can be increased by moving them and the feeder 2A can be sped up to increase the processing capacity and improve the equipment utilization rate. Example 2:

[0020] Please see Figure 2 The difference between this implementation and implementation one is that the discharge end of the three-dimensional turning and drying machine 3A is also connected to a drying conveyor belt 1A. When the weather is bad and the temperature is not high, the turning and drying effect will decrease, and the turning and drying cycle needs to be extended. Therefore, the turning and drying machine will move slower and the feed rate will decrease. At this time, the number of drying conveyor belts 1A at the end of the feeder 2A can be reduced to decrease the feed rate. Instead, one or more drying conveyor belts 1A can be added to the discharge end 4A to perform secondary drying on the dried star anise material, thereby improving the drying effect. Secondary drying overcomes the problem of high moisture content caused by poor drying effect. It realizes the flexible adjustment of the star anise drying mode according to weather conditions and production tasks, maximizes the utilization of weather, site and equipment, and achieves cost reduction and efficiency improvement. Example 3:

[0021] Please see Figures 3-7This utility model provides a drying conveyor belt 1A specifically designed to achieve the technical solutions of Embodiment 1 and Embodiment 2. It includes a connecting base 1, a telescopic bracket 2 fixedly connected to the surface of the connecting base 1, a platform 3 fixedly connected to the top of the telescopic bracket 2, a conveyor roller 4 rotatably connected to the inner side wall of the platform 3, a conveyor belt 5 for transporting octagonal pieces arranged between the conveyor rollers 4, and a plurality of evenly arranged grooves (commonly known in the industry as toothed belts or V-shaped conveyor belts, made of food-grade PVC or PU materials) opened on the surface of the platform 3. A drying shell 6 is also fixedly connected to the surface of the platform 3. A fixed rod 8 is fixedly connected to the inner side wall of the drying shell 6. A heating wire 9 is wound around the surface of the fixed rod 8. A plurality of evenly arranged drying lamps 10 are fixedly connected to the top wall of the inner cavity of the drying shell 6. A plurality of dehumidifying fans 7 for ventilation are also fixedly connected to the outer side wall of the drying shell 6. A universal wheel 13 for movement is fixedly connected to the lower surface of the connecting base 1.

[0022] A first flat plate 11 and a second flat plate 12 are fixedly connected to the surface of the frame 3. The second flat plate 12 is located on the side closer to the drying shell 6, and the height of the first flat plate 11 is greater than the height of the second flat plate 12. A protective cover 15 is fixedly connected to the side wall of the frame 3. A first synchronous pulley 16 and a second synchronous pulley 17 are rotatably connected to the inner side wall of the protective cover 15. A timing belt 18 is provided between the first synchronous pulley 16 and the second synchronous pulley 17, and one end of the second synchronous pulley 17 is fixedly connected to the shaft end of the conveyor roller 4. The lower surface of the frame 3 is fixedly connected to... There is a servo motor 19, whose power output end (700A1-15.0-3kW inverter) is fixedly connected to the shaft end of the first synchronous pulley 16. An electrical control cabinet 14 is fixedly connected to the side wall of the telescopic bracket 2. The dehumidifying fan 7, heating wire 9, drying lamp 10, and servo motor 19 are electrically connected to an external power source through the electrical control cabinet 14. Using the connecting base 1 as the supporting foundation, the height of the platform 3 can be adjusted via the telescopic bracket 2 to accommodate loading devices or unloading containers of different heights. The structure of the telescopic bracket 2 is a standard design for belt conveyors. Figure 7As shown, the rotation of the turntable drives the lead screw to move up and down, and the lead screw drives the conveyor body to rise and fall along the sliding grooves on both sides. Its structure is recorded in the Chinese utility model patent "An Adjustable Belt Conveyor" (publication number CN205312413U), and it has been widely adopted in the industry. Technicians can freely set parameters such as belt length and lifting angle as needed. It is a conventional setting. At the same time, with the help of the universal wheels 13 on the lower surface of the connecting base 1, the production line can be flexibly moved to the required production site to meet the needs of multiple operation scenarios. After the servo motor 19 is started, its power output end drives the first synchronous pulley 16 inside the protective cover 15 to rotate. The power is transmitted to the second synchronous pulley 17 through the timing belt 18, which in turn drives the conveyor roller 4 on the inner side wall of the frame 3 to rotate. The conveyor roller 4 then drives the conveyor belt 5, which has uniform V-grooves on its surface, to rotate, thus ensuring ventilation of the octagonal pieces. After the octagonal pieces are fed from the feed end of the production line, they first pass through the first flat plate 11, which has a higher surface height on the platform 3, to initially break up the piled-up octagonal pieces. Then, they pass through the second flat plate 12, which is closer to the drying shell 6 and has a lower height, to further comb the octagonal pieces into a single layer with a uniform distribution, ensuring that the octagonal pieces do not pile up when they enter the drying area, laying the foundation for uniform drying in the future. After being leveled, the octagonal pieces enter the drying shell 6 with the conveyor belt 5. The heating wire 9, which is wound on the fixing rod 8 on the inner side wall of the drying shell 6, releases heat to conduct heat to the octagonal pieces. At the same time, several drying lamps 10 on the top wall of the inner cavity of the drying shell 6 emit infrared heat to achieve dual heating of "conduction + radiation", which quickly increases the temperature of the drying area to accelerate the evaporation of moisture from the octagonal pieces. During this period, multiple sets of dehumidifying fans 7 on the outer side wall of the drying shell 6 operate continuously to discharge the evaporated moisture in the drying shell 6 in a timely manner, avoiding moisture retention that could lead to mold growth or uneven drying of the octagonal pieces.

[0023] The electrical control cabinet 14 on the side wall of the telescopic support 2 serves as the control core, connecting the dehumidifying fan 7, heating wire 9, drying lamp 10, and servo motor 19 to an external power supply. The heating temperature, conveyor belt speed 5, and dehumidifying fan speed 7 can be adjusted via the control cabinet 14, achieving precise control of drying parameters to reduce manual intervention. The telescopic support 2 allows for flexible adjustment of the platform 3 height, precisely adapting to loading and unloading containers of different heights. Combined with the universal wheels 13 on the lower surface of the connecting base 1, the entire production line can be moved flexibly, completely breaking the limitations of traditional drying equipment's "fixed installation and single-site operation." It can integrate into factory assembly line operations as well as meet the needs of small workshops or temporary production sites, adapting to diverse production scenarios. Furthermore, the first flat plate 11 and the second flat plate 12 on the surface of the platform 3 form a "high-low" structure. The combination of materials, along with the uniform grooves on the surface of the conveyor belt 5, allows the octagonal pieces to be initially broken up and then combed into a single, evenly distributed layer after loading, preventing them from piling up. Once inside the drying shell 6, the conductive heating from the heating wire 9 and the radiant heating from the drying lamp 10 create a dual heating mode, rapidly increasing the drying temperature. Furthermore, the dehumidifying fan 7 on the outer wall of the drying shell 6 promptly removes moisture, effectively preventing the octagonal pieces from becoming "overly dry on the outside and damp on the inside" due to uneven heating. To address the issue of star anise moisture content being uniformly reduced to 8%-10%, while maintaining bright shell color and minimizing volatile oil loss, the quality of the finished product is significantly improved. The continuous conveying mode driven by the servo motor 19, combined with a dual heating system, greatly shortens the drying cycle, enabling continuous batch production of star anise and significantly improving drying efficiency. Meanwhile, the electrical control cabinet 14 on the side wall of the telescopic bracket 2 can centrally control the dehumidification fan 7, heating wire 9, drying lamp 10, and servo motor 19, precisely adjusting the heating temperature, conveyor belt speed 5, and dehumidification fan speed 7. This eliminates the need for frequent manual parameter adjustments or flipping of the star anise, significantly reducing manual operation and lowering labor costs. The protective cover 15 effectively protects the synchronous pulley, timing belt 18, and other transmission components, preventing foreign objects from being caught or accidental contact by personnel. All electrical components are uniformly controlled through the electrical control cabinet 14, with a simple operating interface that allows even beginners to quickly get started, balancing equipment stability, safety, and ease of operation.

[0024] Using the connecting base 1 as the supporting foundation, the height of the platform 3 can be adjusted by the telescopic bracket 2 to accommodate loading devices or unloading containers of different heights. Simultaneously, with the help of the casters 13 on the lower surface of the connecting base 1, the production line can be flexibly moved to the required production site to meet the needs of multiple operation scenarios. After the servo motor 19 starts, its power output drives the first synchronous pulley 16 inside the protective cover 15 to rotate. The power is then transmitted to the second synchronous pulley 17 via the timing belt 18, which in turn drives the conveyor roller 4 on the inner wall of the platform 3 to rotate. The conveyor roller 4 then drives the conveyor belt 5, which has uniformly V-shaped openings on its surface, to rotate. Baffles are provided on both sides of the V-shaped conveyor belt 5 (as shown in the figure). (Not shown) After the star anise is fed from the production line, it first passes through the first flat plate 11 on the platform 3, which has a higher surface height, to initially break up the piled-up star anise. Then, it passes through the second flat plate 12, which is closer to the drying shell 6 and has a lower height, to further comb the star anise into a single layer with a uniform distribution. This ensures that the star anise does not pile up when it enters the drying area, laying the foundation for uniform drying. After being leveled, the star anise enters the drying shell 6 with the conveyor belt 5. The heating wire 9, which is wound on the fixing rod 8 on the inner wall of the drying shell 6, releases heat to conduct heat to the star anise. At the same time, several drying lamps 10 on the top wall of the inner cavity of the drying shell 6 emit infrared heat to achieve "conduction + The dual heating of "radiation" rapidly increases the temperature of the drying area to accelerate the evaporation of moisture from the star anise. During this period, multiple sets of dehumidifying fans 7 on the outer wall of the drying shell 6 operate continuously to promptly remove the evaporated moisture from the drying shell 6, preventing moisture retention that could lead to mold growth or uneven drying of the star anise. The electrical control cabinet 14 on the side wall of the telescopic bracket 2 serves as the control core, connecting the dehumidifying fans 7, heating wires 9, drying lamps 10, and servo motors 19 to an external power source. The heating temperature, conveyor belt speed 5, and dehumidifying fan speed can be adjusted through the electrical control cabinet 14 to achieve precise control of drying parameters and reduce manual intervention.

[0025] Testing has shown that this method effectively ensures the moisture content of star anise is uniformly reduced to 8%-10%, while maintaining a bright shell color and minimal loss of volatile oils, significantly improving the quality of the finished product. The continuous conveying mode driven by 19 servo motors achieves a drying-to-folding ratio of ≤2:1 and a material bulk density ≥350kg / m³. 3 .

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
