Description

Technical Field

[0001] This application relates to a drying and screening device for medicinal and edible homologous granules, belonging to the technical field of medicinal and edible homologous granule production equipment. Background Technology

[0002] Currently, most medicinal and edible granules are granule dosage forms made from natural medicinal and edible plants with specific effects. Since these plants often contain a large amount of polysaccharides, polyphenols, and other effective ingredients, the granules are prone to absorbing moisture and clumping after granulation. Therefore, the granules need to be dried and sieved in time after granulation to prevent clumping. In addition, when people brew medicinal and edible granule preparations, the uneven particle size often makes it difficult to dissolve some of the larger particles. Therefore, it is necessary to sieve the granules to ensure their quality and improve the user experience.

[0003] Chinese patent CN218133178U discloses a multi-stage screening device for the production of medicinal and edible homologous granules, including a working box, a slide bar, a slide seat, a distributing hopper, a primary screening screen, a secondary screening screen, a discharge assembly, and a drive assembly. It can perform multi-stage screening and conveying discharge operations on medicinal and edible homologous granules in one operation, reducing manual operation and improving the operability of the device. Although this patent can classify and screen medicinal and edible homologous granules, it does not dry the medicinal and edible homologous granules. If the medicinal and edible homologous granules are not dried in time, problems such as granule agglomeration and increased granule stickiness may occur, making it impossible to screen the medicinal and edible homologous granules smoothly.

[0048] refer to Figure 1-8This application discloses a drying and sieving device for medicinal and edible homologous granules, comprising: a feeding trough 10, with a plurality of feeding holes 11 provided on the bottom surface of the feeding trough 10; an operating box 20, with an opening at the top and the top of the operating box 20 fixedly connected to the bottom of the feeding trough 10; a drying component 30, disposed within the operating box 20, with its upper end connected to the bottom of the feeding trough 10 and connected to a hot air blower 50 for drying medicinal and edible homologous granules; and a sieving component 40, also disposed within the operating box 20 and located below the drying component 30, the radial cross-sectional area of ​​the sieving component 40 being larger than that of the drying component 30, and the sieving component 40 including a first sieve. A first screening screen 41 and a second screening screen 42 are provided. The first screening screen 41 is located above the second screening screen 42. The area of ​​the second screening screen 42 is larger than that of the first screening screen 41, and the aperture of the first screening screen 41 is larger than that of the second screening screen 42. A first output port 21 and a second output port 22 are provided on the same outer side wall of the operating box 20. The first output port 21 is used to output the material trapped in the first screening screen 41 and is connected to the first collection box 60. The second output port 22 is used to output the material trapped in the second screening screen 42 and is connected to the second collection box 70. A waste collection trough 90 is provided inside the operating box 20 and below the second screening screen 42. A vibration motor 80 is used to make the operating box 20 vibrate.

[0049] In this setup, the medicinal and edible granules are placed in the feeding trough 10. Under the vibration force provided by the vibrating motor 80, the granules enter the drying assembly 30 through the feeding hole 11. The hot air in the drying assembly 30 dries the granules. After drying, the granules enter the first screening screen 41 for screening. Larger particles remain on the first screening screen 41. The particles remaining on the first screening screen 41 enter the first collection box 60 through the first output port 21 under the action of vibration and gravity. The remaining particles enter the second screening screen 42 for secondary screening. After secondary screening on the second screening screen 42, particles of moderate size remain on the second screening screen 42. Under the action of vibration and gravity, they enter the second collection box 70 through the second output port 22. The remaining particles that are too small enter the waste collection trough 90. This device can effectively improve the drying efficiency of medicinal and edible granules. At the same time, by setting up secondary sieving, it can effectively ensure the uniformity of the particle size of medicinal and edible granules, improve the quality of the product, and facilitate subsequent drinking and brewing.

[0050] Specifically, there is no specific limitation on the connection method between the drying component 30 and the bottom of the feeding tank 10. It can be a threaded connection, a snap-fit ​​connection, an adhesive connection, or a welding connection, as long as it can achieve a fixed connection between the drying component 30 and the bottom of the feeding tank 10.

[0051] Specifically, the hot air blower 50 is located outside the control box 20, and can be located on one side outside the control box 20.

[0052] Specifically, the bottom of the control box 20 is equipped with a vibration damping spring to prevent vibration from being transmitted to the ground and causing abnormal vibration of the equipment.

[0053] In one embodiment, the drying assembly 30 includes an air outlet 31 and several drying tubes 32. The air outlet 31 is hollow inside and has a hollow channel 312 on its side wall. The hollow channel 312 is connected to the hot air blower 50 through a first ventilation duct 51. Several first ventilation holes 311 are evenly arranged on the inner side of the hollow channel 312. With this configuration, the hollow channel 312 on the side wall of the air outlet 31 allows hot air from the hot air blower 50 to enter the interior of the air outlet 31. The evenly arranged first ventilation holes 311 on the inner side of the hollow channel 312 ensure uniform airflow from the air outlet 31, achieving uniform and effective drying of the particles in the drying tubes 32 and preventing uneven heating of the particles in the drying tubes 32, which would affect the drying quality of the particles.

[0054] Specifically, the size and number of the first ventilation holes 311 are not specifically limited, as long as they can achieve uniform airflow to dry the particles in the drying tube 32.

[0055] For details, please refer to Figure 7 The top of the drying tube 32 and the air outlet 31 are both connected to the bottom of the feeding trough 10. The drying tube 32 is connected to the infusion hole 11 at the bottom of the feeding trough 10, which allows the medicinal and edible particles in the feeding trough 10 to enter the drying tube 32.

[0056] In one embodiment, the drying tube 32 is disposed inside the air outlet 31, and a plurality of second ventilation holes 321 are evenly provided on the drying tube 32. The top end of the drying tube 32 is connected to the feed hole 11. With this configuration, the medicinal and edible granules enter the drying tube 32 through the feed hole 11, and hot air is output to the outside of the drying tube 32 through the first ventilation hole 311 in the air outlet 31. By providing a plurality of second ventilation holes 321 on the drying tube 32, hot air can enter the interior of the drying tube 32, further improving drying efficiency and uniformity. Furthermore, the second ventilation holes 321 on the drying tube 32 can also re-divert the medicinal and edible granules, further improving drying efficiency.

[0057] Specifically, the size and number of the second ventilation holes 321 are not specifically limited, as long as they can achieve uniform drying of the medicinal and edible granules.

[0058] In one implementation, the air outlet 31 is cylindrical. This configuration increases the air outlet area of ​​the air outlet 31, allowing for better and more even distribution of hot air to the drying tube 32. The larger air outlet area also improves the drying efficiency of the medicinal and edible granules.

[0059] In one embodiment, there are at least three drying tubes 32.

[0060] This setup allows for effective diversion of the medicinal and edible granules, enabling them to better receive hot air drying. If only one drying tube 32 is used, all the granules are concentrated in one pipe. Even with uniform airflow from the air outlet 31, the large number of granules prevents external hot air from reaching the center of the drying tube 32, hindering drying of the granules in that area. This results in uneven drying, with some granules clumping together, affecting subsequent sieving. If there are more than three drying tubes 32, the diameter of their cross-section decreases. While this allows for diversion of more granules, it slows the flow rate, reducing drying efficiency. Furthermore, the small diameter of the drying tubes can cause blockage, preventing proper drying. Using three drying tubes 32 ensures both the flow rate and drying efficiency of the granules.

[0061] In one embodiment, the drying assembly 30 further includes a first ventilation duct 52, one end of which is connected to the hot air blower 50, and the other end of which is positioned above the second screen. With this configuration, by placing the first ventilation duct 52 above the second screen 42, secondary drying can be performed on medicinal and edible homologous granules of suitable particle size during the sieving process, ensuring the dryness of the packaged granules and preventing adhesion.

[0062] In one embodiment, one end of the first screening screen 41 is connected to the side wall of the operating box 20 with the first output port 21, and the other end of the first screening screen 41 is connected to the side wall of the operating box 20 away from the operating box 20 with the first output port 21 through a fastener 411.

[0063] In this configuration, when the particles on the first screening screen 41 are output, the first screening screen 41 is connected to the first output port 21, which allows the particles on the first screening screen 41 to directly enter the first collection box 60, reducing the operator's workload and improving the convenience of the device.

[0064] In one implementation, the angle between the first screening screen 41 and the horizontal plane is 10-25°. Under this setting, the angle between the first screening screen 41 and the horizontal plane can be set to different angles according to specific practical needs.

[0065] Specifically, when drying and sieving the medicinal and edible granules, the angle between the first screening screen 41 and the horizontal plane is determined. The dried granules enter the first screening screen 41. Due to the angle, the granules remaining on the first screening screen 41 enter the first collection box 60 through the first output port 21 under the action of vibration and gravity, thereby collecting the granules.

[0066] Specifically, a first partition 412 can be provided at the edge of the first screening screen 41. The first partition 412 is connected to the inner wall of the operating box 20. When the particles are dried and screened, the presence of the first partition 412 can prevent the particles from falling off the first screening screen 41 during the particle output process.

[0067] In one embodiment, the screening assembly 40 also includes a telescopic rod 421. One end of the second screening screen 42 is provided with a first angle adjuster 422. The first angle adjuster 422 is connected to the side wall of the operating box 20 with a second output port 22. The other end of the second screening screen 42 is connected to one end of the telescopic rod 421. The other end of the telescopic rod 421 is fixedly connected to the operating box 20.

[0068] In one implementation, the telescopic rod 421 is fixed to the bottom. When at the bottom, the waste collection trough 90 can be fixed within the operating housing 20, with the telescopic rod 421 fixed inside. Alternatively, a through hole can be provided in the waste collection trough 90 for the telescopic rod 421 to be fixed to the bottom plate of the operating housing 20. In this method, the waste collection trough 90 cannot be removed; an output hole needs to be provided at the bottom. A brush or other tool is used to sweep the waste from the waste collection trough 90 into the hole, thus cleaning the waste from the waste collection trough 90.

[0069] In a preferred embodiment, a fixed seat is provided on the side wall of the operating box 20, which is located away from the second output port 22, and the telescopic rod 421 is fixedly connected to the fixed seat.

[0070] In one implementation, the angle between the second screening screen 42 and the telescopic rod 421 is 45-90°. With this setting, by adjusting the angle between the second screening screen 42 and the telescopic rod 421, the particle output speed can be adjusted, effectively improving screening and output efficiency.

[0071] In one implementation, a second angle adjuster 423 is provided at the end of the telescopic rod 421 connected to the second screening screen 42. With this configuration, changes in the height of the telescopic rod 421 cause changes in the angle of the second angle adjuster 423, thereby changing the angle between the second screening screen 42 and the telescopic rod 421. The smaller the angle, the greater the gravitational force on the particles on the second screening screen 42, and the faster they enter the second collection box 70 through the second output port 22.

[0072] Specifically, a second partition 424 can be provided on the edge of the second screening screen 42. The end of the second partition 424 near the second output port 22 is a retractable rubber bellows. Even if the angle of the second screening screen 42 changes, the second screening screen 42 can still be connected to the inner wall of the operating box 20. When drying and screening the particles, the angle of the second screening screen 42 is adjusted. During the particle output process, the presence of the second partition 424 can prevent the particles from falling off the second screening screen 42.

[0073] The above description is merely an embodiment of this application, and the scope of protection of this application is not limited to these specific embodiments, but is determined by the claims of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the technical concept and principles of this application should be included within the scope of protection of this application.
