Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine drying, and particularly to a flip-type traditional Chinese medicine circulating drying system and a drying method. Background Art

[0002] After traditional Chinese medicines are collected, cleaned, and sorted, most of them need to be processed except for a few used for preservation. Crushing and drying technologies are important links. The traditional crushing method uses a structure of roller rolling. However, this crushing method results in excessive crushing effect, making most of the traditional Chinese medicines become powdery, leading to excessive waste and the situation that the shapes of traditional Chinese medicines are irregular and unusable. In addition, the traditional drying method is natural drying. Although it is simple to operate and low in cost, it has disadvantages such as strong seasonality, large space occupation, low production efficiency, and easy mildew and pollution. In order to better complete the drying work, the industry has started to use traditional Chinese medicine drying mechanisms. The most representative ones are drum-type and vertical dryers. However, the stirring and conveying in some drying boxes are likely to stir the traditional Chinese medicines into powder, affecting the shapes of the medicines. In addition, because the drying situation cannot be checked at any time, the drying effect on different traditional Chinese medicines becomes worse. Moreover, the existing drying mechanisms have not formed a complete process system, and the next process cannot be carried out after one process is completed, and an integrated process of crushing - drying - packing has not been formed.

[0003] Therefore, there is an urgent need for a drying system that can solve problems such as few formed traditional Chinese medicines, inability to directly observe the drying effect, and failure to form an integrated process of crushing - drying - packing during the crushing and drying of traditional Chinese medicines.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. Protect the integrity of the shape of Chinese medicinal materials

[0036] In the crushing part of this circulating drying system, a crushing unit is used to crush Chinese medicinal materials in a "hammering" manner. By the irregular rotational movement of the hammer heads around the hammer shafts, the Chinese medicinal materials are hammered and crushed into shape. The traditional rolling method is abandoned, reducing the medicinal materials from becoming granular or powdery and increasing the number of formed Chinese medicinal materials. Secondly, the transport table in the flip - type drying device moves reciprocally, and the first and second drying mechanisms perform convective drying on the transport table, which can not only enhance the drying effect but also avoid mechanical damage caused by stirring, effectively protecting the shape of the Chinese medicinal materials.

[0037] 2. Facilitate the intuitive observation of the drying situation

[0038] The flip - type drying device of the present invention can be flip - processed, and the operator can directly observe the state changes of Chinese medicinal materials during the drying process, such as color, texture, etc. Intuitive observation can help the operator promptly discover possible problems during the drying process, such as excessive or insufficient local drying, and then promptly adjust the drying parameters, judge whether the drying progress is normal, and can promptly adjust the drying temperature or time to ensure the drying quality.

[0039] 3. Form a complete process system and achieve process connection

[0040] This flip - type Chinese medicinal material circulating drying system forms an integrated process of crushing - drying - packing. Each process step from feeding, drying to discharging is connected. After drying is completed, the packaging device conducts packaging, reducing manual intervention, lowering labor intensity, and ensuring the stability and consistency of product quality.

[0041] 4. The cleaning and air - drying device conducts cleaning and pre - air - drying

[0042] This cleaning and air - drying device cleans the Chinese medicinal materials, and at the same time separates the moisture in the Chinese medicinal materials containing aqueous solution. The moisture flows back from the first tabletop. Meanwhile, the air - drying device conducts pre - drying treatment on the Chinese medicinal materials, shortening the drying duration and also avoiding the direct drying of Chinese medicinal materials with excessive aqueous solution, which may lead to a deteriorated drying effect.

[0071] The packaging device 400 includes: a control box 405 and a packaging mechanism, and the control box 405 is electrically connected to the flip-type drying device 300 and the packaging mechanism.

[0072] The crushing device 100 crushes and mixes the Chinese medicinal materials. The mixed Chinese medicinal materials are cleaned by the ultrasonic cleaning machine 209 in the cleaning and air-drying device 200, and the cleaned Chinese medicinal materials are pre-dried by the air-drying device.

[0073] Refer to Figures 2 - 4 , in order to improve the crushing and stirring effects, a crushing device 100 is designed, including:

[0074] The first base 101 is composed of two groups of frames and multiple support steels, and the frames are rectangular;

[0075] The first feed inlet 106 is installed on the first support frame 102 and the second support frame 103, and the first support frame 102 and the second support frame 103 are installed on the top of the first base 101; a first support block 104 is installed on the side wall of the first support frame 102, and a second support block 105 is installed on the side wall of the second support frame 103; the bottom of the tail end of the first feed inlet 106 is fixedly connected to the protective shell 116, specifically connected to the locking port 133 at the top of the protective shell 116, and at the same time docked at the side of the crushing unit group, corresponding to the position of the rolling pipe group 124 in the crushing unit group;

[0076] The crushing unit group, the overall shell of the crushing unit group is vertically spliced by the protective shell 116 and the second feed inlet 115; the side of the crushing unit group is communicated with and connected to the first feed inlet 106, and the crushing unit group is installed on the top of the first base 101. The crushing unit group includes:

[0077] The protective shell 116 is installed on the top of the first base 101, and at the same time, a third hydraulic rod 123 is arranged outside the protective shell 116 to increase the fastening between each module on the protective shell 116;

[0078] The second rotating shaft 120 is installed on the top of the protective shell 116, and the end of the second rotating shaft 120 is located outside the protective shell 116;

[0079] The second feed inlet 115 is installed on the top of the protective shell 116. A grid baffle 118 and a grid block 119 are arranged in the second feed inlet 115, and the grid baffle 118 and the grid block 119 are connected to the second rotating shaft 120; one end of the rotating part 121 is connected to the end of the second rotating shaft 120, and the other end of the rotating part 121 is installed on the outer wall of the second feed inlet 115 through the second hydraulic rod 122; at this time, the telescopic movement of the second hydraulic rod 122 drives the second rotating shaft 120 to rotate, and the grid baffle 118 rotates with the second rotating shaft 120 to block the materials in the second feed inlet 115. When not blocked, the grid block 119 and the first sieve plate 129 surround the rolling round pipe to prevent the materials from flying out. The second feed inlet 115 is provided to mix and stir a variety of Chinese medicinal materials to prevent the situation of uneven mixing caused by input from one feed inlet.

[0080] Inside the crushing unit, there are several axially connected rolling tube groups 124. Multiple rolling tube groups 124 can be connected in reverse or in the forward direction. To maintain the running balance of the rolling tube groups 124, the rolling tube groups 124 are installed inside the protective shell 116. The rolling tube group 124 includes: a rolling round tube and a sieve plate. The end of the rolling round tube penetrates through the protective shell 116 and is rotatably connected to a first bearing seat 132 arranged outside the protective shell 116. The sieve plate is arranged on the outer periphery of the rolling round tube and is fixed to the inner wall of the protective shell 116.

[0081] The sieve plate includes a first sieve plate 129 and a second sieve plate 130. The first sieve plate 129 and the second sieve plate 130 are fixedly connected inside the protective shell 116 and are both distributed around the outer periphery of the rolling round tube. The first sieve plate 129 is in a straight plate shape, and the second sieve plate 130 is in an arc shape, and sieve openings are arranged inside both of them.

[0082] A discharge port 131 is also arranged below the crushing unit. The discharge port 131 is installed at the bottom of the protective shell 116 and is arranged at the bottom of the rolling tube group 124 for convenient collection.

[0084] Several rotor disks 126. The middle of the rotor disk 126 is penetrated and connected by a first rotating shaft 125. The rotor disks 126 are connected in series in an orderly manner through circumferentially arranged hammer shafts 127. There is only one hammer head 128 on each hammer shaft 127. The hammer head 128 is arranged between adjacent rotor disks 126, and adjacent hammer heads 128 are installed on adjacent hammer shafts 127. The distributed design of the hammer heads 128 makes the rotation effect of the rotor disks 126 better, avoids situations such as deviation during the rotation of the rotor disks 126, and can also fully mix different Chinese medicinal materials, with a better mixing effect. At the same time, it is quite different from the traditional blade-type slicing and mixing states. The rolling round tube is mainly for mixing and crushing, rather than cutting into powders or granules, which is very different from the prior art.

[0085] Refer to Figures 2 - 3 , to avoid the situation of Chinese medicinal materials forming lumps and entangling, a dispersing mechanism 109 is arranged at the tail of the first feed inlet 106. The dispersing mechanism 109 is rotatably connected to the first support frame 102. The dispersing mechanism 109 includes:

[0086] Dispersing rollers 117. Both ends of the dispersing rollers 117 are installed with first gears 114.

[0087] The dispersing arms 110 are provided. A balance roller 111 is connected between the two dispersing arms 110. The head of the dispersing arm 110 is connected between the dispersing roller 117 and the first gear 114. The tail of the dispersing arm 110 is rotatably connected to the first support block 104. The top of the dispersing arm 110 is provided with a first motor 113. The output end of the first motor 113 is connected to the first gear 114. The bottom of the dispersing arm 110 is rotatably connected to the second support block 105 through a first hydraulic rod 112.

[0088] A dispersing mechanism 109 is provided. A number of protrusions are provided on the dispersing roller 117, which can efficiently impact and disperse Chinese medicinal materials in a clumped or knotted state during rotation. The dispersing arm 110 is rotatably connected to the first support frame 102, and can adapt to dispersing more Chinese medicinal materials in different clump sizes. The dispersing roller 117 can also disperse slightly smaller clumped Chinese medicinal materials, avoiding affecting the crushing efficiency and improving the stirring and crushing effects.

[0089] Refer to Figures 5 - 6 , in order to improve the cleanliness of Chinese medicinal materials and reduce the energy consumption for drying, a cleaning and air-drying device 200 is designed, including:

[0090] The first support 201 is composed of a rectangular frame formed by horizontally and vertically connecting a plurality of square tubes. At the same time, a number of third rotating shafts 202 are fixed on the first support 201 through second bearing seats 203, and a number of second gears 204 are installed on the third rotating shafts 202;

[0091] The first tabletop is installed inside the first support 201. The first tabletop includes: a washing liquid tank 205 and an inclined tank 206. The washing liquid tank 205 and the inclined tank 206 are respectively the head and the tail of the first tabletop. The washing liquid tank 205 is a region formed by the first tabletop being recessed downward, and the inclined tank 206 is a region where the tail of the first tabletop inclines towards the middle of the first tabletop. The height of the middle of the first tabletop is lower than that of the tail of the first tabletop. At the same time, a number of third gears 207 are installed on the inner wall of the washing liquid tank 205;

[0092] The conveyor belt 208 is laid around the outer circumference of a number of third rotating shafts 202 and passes through the ultrasonic cleaning machine 209, and is engaged with the second gears 204 and the third gears 207 for transmission. The conveyor belt 208 is continuously kept in a tensioned state, avoiding the problem of slipping in traditional belt transmission and the situation of low processing efficiency. At the same time, the conveyor belt 208 can be any one that can convey Chinese medicinal materials in the prior art.

[0093] The ultrasonic cleaning machine 209 is installed in the washing liquid tank 205;

[0094] The air-drying device includes: the air-drying cover 210 has through ends at the head and the tail, and the air-drying cover 210 is installed at the inclined tank 206 on the first support 201; a first fan 211 penetrating through the inside of the end cover is embedded at the top of the air-drying cover 210;

[0095] The first heating pipe 212 and the first air deflector 213 are installed inside the air drying hood 210. The first heating pipe 212 is arranged at the bottom end of the first fan 211, and the first air deflector 213 is arranged between the first heating pipe 212 and the first fan 211. The first air deflector 213 makes the air blown out by the first fan 211 more concentratedly blown onto the first heating pipe 212, while also avoiding wind force loss and improving the air drying effect.

[0096] The second motor 214 is installed on the frame in the middle of the first bracket 201, and the output end of the second motor 214 is connected to the second gear 204 on the frame at the bottom of the first bracket 201.

[0097] With the setting of the cleaning and air drying device 200, through the movement of the conveyor belt 208, the ultrasonic cleaning machine 209 cleans the Chinese medicinal materials in the cleaning liquid tank 205. Along with the movement of the conveyor belt 208, the hot air from the first heating pipe 212 is blown onto the Chinese medicinal materials by the first fan 211, and the cleaning liquid on the Chinese medicinal materials flows back into the cleaning liquid tank 205 through the inclined groove 206. The purpose of designing the air drying device is to reduce the drying time and energy consumption. At the same time, the cleaning liquid can also flow back under the blowing of the wind, and the cleaning liquid is recycled, while also avoiding the excessive drying time caused by the residue of the cleaning liquid in the next step.

[0098] Refer to Figures 7 - 11 , in order to observe the drying situation of the Chinese medicinal materials at any time and have a complete drying process, a flip - type drying device 300 is specifically designed, and it further includes:

[0099] A second bracket 301, with a number of first box covers 303 provided on the front and rear sides of the second bracket 301;

[0100] A transport table 302, installed inside the second bracket 301.

The inner side walls of the two outermost guide strips 305 are installed with first guide rails 306, and a fourth gear 309 fixed to the side wall of the guide strip 305 is installed at each end of the first guide rail 306; the first guide rails 306 are installed on both sides of the guide strips 305 in the middle, and a fourth gear 309 fixed to the side wall of the guide strip 305 is installed at each end of the first guide rail 306; the chain 307 is installed in the first guide rail 306 and is connected in cooperation around the fourth gear 309. The chain 307 (not all shown in the figure) extends out a chain pulley 308; the pallet 310 is installed on the top of the two chain pulleys 308;

[0101] The first drying mechanism, the outside of the first drying mechanism is fixedly connected to the first locking frame 324, and the first locking frame 324 is rotationally connected to the top of the second bracket 301 through the second connecting page 323;

[0102] The second drying mechanism, the second drying mechanism is fixedly connected inside the second bracket 301, and the second drying bracket is arranged below the transport table 302.

[0103] A number of first drying mechanisms are arranged along the running direction of the chain 307 to form a first drying unit. The structure of the second drying mechanism is the same as that of the first drying mechanism. The second drying unit and the first drying unit are arranged oppositely in the direction of the air flow; and the first locking frame 324 is sleeved on the outer periphery of the first drying unit and fixedly connected through the second connecting page 323. The second connecting page 323 is also installed on the second bracket 301, so that the first drying mechanism and the second connecting page 323 are rotatable, such as hinges, hinges, etc.

[0104] Through the aforementioned flip-type drying device 300, the wind force and heat of the first drying mechanism and the second drying mechanism can be adjusted in real time according to the temperature and humidity detection sensor. At the same time, the first drying mechanism can be rotated and folded, and the drying effect of Chinese herbal medicines can be observed intuitively. Equipped with a temperature and humidity detection sensor, it can be accurately set through the control box 405 according to the drying requirements of different Chinese herbal medicines, and the temperature and humidity changes in the drying environment can be monitored in real time. When the humidity exceeds the set value, the exhaust fan starts to discharge moisture; when the temperature is abnormal, the heating and blowing effect are adjusted, greatly improving the drying effect and the quality of the medicinal materials.

[0105] To further enhance the drying effect and avoid the influence of too long drying time and overheating on the efficacy of Chinese herbal medicines, a first drying mechanism is designed, including:

[0106] The third bracket 311, several first fixing plates 312 are embedded in the inner wall of the third bracket 311. The top of the third bracket 311 is connected to the third motor 313 through the third base 314. The output end of the third motor 313 passes through the first fixing plate 312, and the output end of the third motor 313 is installed with the second fan 315; the design of the second fan 315 can effectively exchange the dry air with the air on the surface of the Chinese herbal medicines, increasing the drying effect, and at the same time can also avoid the problem that the existing stirring drying is easy to crush the dry (brittle) medicinal materials, improving the practicability of Chinese herbal medicines.

[0107] The second heating tube 316, the second heating tube 316 is arranged beside the second fan 315, and the end of the second heating tube 316 passes through the first fixing plate 312 and is fixedly connected to the filament box 317 arranged on the top of the first fixing plate 312; the hot air flow is blown to the Chinese herbal medicines through the second fan 315 to increase the drying effect.

[0108] The second fairing 318 is sleeved on the outer circle of the second fan 315 and fixed to the bottom of the first fixing plate 312, concentrating the hot air flow and preventing the hot air flow from overflowing.

[0109] The first deflector 321 is installed on the third bracket 311 and located below the second fan 315. A number of first ventilation openings 322 are provided on the first deflector 321, and the positions of the first ventilation openings 322 are vertically aligned with those of the second fan 315. Through the design of the first deflector 321, the air flow forms a convection, bundles the hot air flow, and enhances the air-drying effect.

[0110] Meanwhile, a second deflector 319 is provided inside the first fixing plate 312 of the first drying mechanism. The second deflector 319 is fixed to the third bracket 311, and a gap is maintained between the second deflector 319 and the first fixing plate 312. A number of second ventilation openings 320 are provided on the second deflector 319. The design of the second deflector 319 enables the front and rear sides of the transport table 302 to be wrapped by the hot air flow, avoiding waste of the hot air flow. In addition, it also promotes the formation of an air flow barrier and isolation on the front and rear sides of the transport table 302, reducing contact with the external environment.

[0111] Refer to Figures 12 - 16 , for integrated packaging, the present invention designs a packaging device 400, including: a fourth bracket 401, a hoist 402, a fifth bracket 403, a hopper 404, a control box 405, a packing mechanism, etc.

[0112] The hoist 402 is installed at the top of the fourth bracket 401, and the head end of the hoist 402 is connected to the hopper 404. The fifth bracket 403 is arranged adjacent to the fourth bracket 401. The top of the fifth bracket 403 is fixedly connected to the collecting plate 407 through a first connecting plate 406. The two ends of the collecting plate 407 are respectively connected to the tail end of the hoist 402 and a second connecting plate 408. The second connecting plate 408 is connected to the slideway 415. A first cylinder 409 is installed on the side wall of the first connecting plate 406, and the piston rod 410 on the first cylinder 409 abuts against the bottom of the collecting plate 407. The piston rod 410 moves reciprocally, enabling the dried Chinese medicinal materials to smoothly move to the next packaging location, avoiding jamming of the Chinese medicinal materials and resulting in the inability to continue transportation and packaging.

[0113] On one side of the fifth support 403, a tape roller 411, a driven roller 412, an anti-overflow plate 413, a blanking channel 414, a slideway 415, and a packing mechanism are successively installed from top to bottom. The sealing bag 416 is wound around the tape roller 411, bypasses the driven roller 412, and adheres along the outer wall of the anti-overflow plate 413 and the inner wall of the blanking channel 414 until it adheres to the outer wall of the slideway 415 (the winding method of the sealing bag 416 is not shown in the figure). The blanking channel 414 is installed on the fifth support 403 through the first connecting rod 417. By proceeding in this way, a sealing bag 416 can be encapsulated into a cylindrical structure, and at the same time, the traditional Chinese medicine materials in the slideway 415 can be packaged together.

[0114] On the side of the fifth support 403, a third connecting plate 418 is provided. A guide disk group 420 and a heating disk group 419 are arranged on the third connecting plate 418. The heating disk group 419 and the guide disk group 420 are arranged vertically and each consists of two horizontally arranged disks. The middle parts of the heating disk group 419 and the guide disk group 420 are in contact with the outer wall of the slideway 415. The heating disk group 419 is arranged between the two guide disk groups 420. The disks of the guide disk group 420 are rotatable. Specifically, the left disk rotates clockwise and the right disk rotates counterclockwise, so that they roll over the sealing bag 416 and drive the sealing bag 416 to move downward along the outer wall of the blanking channel 414. The guide disk group 420 drives the two sides of the sealing bag 416 to be pressed together and move downward, and the heating disk group 419 heat-seals the two sides of the sealing bag 416.

[0115] The slideway 415 is connected to the second connecting plate 408. The blanking channel 414 is sleeved on the top of the slideway 415. Two guide rods 421 also extend downward from the bottom of the blanking channel 414. The guide rods 421 are arranged outside the slideway 415. The arrangement of the guide rods 421 can prevent the sealing bag 416 from turning outwards when it starts to move downward along the outer wall of the slideway 415, and can comb the sealing bag 416 to move normally along the outer wall of the slideway 415.

[0116] Refer to Figure 16 , to enhance the encapsulation effect, the present invention designs a packing mechanism, including:

[0117] A first fixing block 423 and a second fixing block 424 are sleeved on the first pillar 422. The second fixing block 424 is rotatably connected to the first pillar 422. The first fixing block 423 is installed on the side wall of the fifth support 403 and is located at the bottom of the third connecting plate 418. The end of the first pillar 422 is connected to the fourth connecting plate 425. The fourth connecting plate 425 is rotatable with the first pillar 422, but the position of the fourth connecting plate 425 does not move. The setting of the fourth connecting plate 425 is to prevent the second fixing block 424 from having too large a stroke, resulting in the separation of the second fixing block 424 from the first pillar 422.

[0118] The heat-sealing module 426 is connected to the inner walls of the first fixing block 423 and the second fixing block 424 through the second support column 427. The heating areas in the heat-sealing module 426 are arranged oppositely. At the same time, a first spring 428 is also arranged on the outer wall of the second support column 427. The setting of the first spring 428 enhances the flexible encapsulation effect of the heat-sealing module 426 and avoids the problem of rigid posture when the heat-sealing module 426 is docked.

[0119] The third support column 429 is located below the heat-sealing module 426. The third support column 429 is installed on the side of the first fixing block 423. At the same time, a third fixing block 430, a slidable guiding ring 431, and a fourth fixing block 432 are arranged on the third support column 429. The third fixing block 430, the guiding ring 431, and the fourth fixing block 432 are located between the heat-sealing modules 426. The guiding ring 431 is arranged between the third fixing block 430 and the fourth fixing block 432. A fifth fixing block 433 is installed at the top of each of the third fixing block 430 and the fourth fixing block 432. A tray 437 is installed at the top of the fifth fixing block 433, and a tool set 434 is installed at the bottom of the fifth fixing block 433. And the tool set 434 is arranged between the third fixing block 430 and the fourth fixing block 432.

[0120] The fourth support column 435 is located below the heat-sealing module 426. The fourth support column 435 penetrates the first fixing block 423 and is fixedly connected to the third fixing block 430. The fourth support column 435 can be a piston rod 410 and is connected in cooperation with a hydraulic cylinder so as to achieve the characteristic that the fourth support column 435 can stretch. The third fixing block 430 can move horizontally, and the relative position of the fourth fixing block 432 remains unchanged. At this time, the normal cutting operation of the tool set 434 can be ensured.

[0121] The collection box 436 is installed on one side of the fifth bracket 403 and is arranged at the bottom end of the packing mechanism to pack and collect the packaged Chinese medicinal materials.

[0122] The present invention also provides a flip-type Chinese medicinal material circulating drying method, which adopts the above flip-type Chinese medicinal material circulating drying system, and the operation steps are as follows:

[0123] S1, Put the Chinese medicinal materials into the first feed inlet 106, and after being stirred, separated, and screened by the crushing unit, collect them at the discharge port 131;

[0124] S2, The Chinese medicinal materials in the discharge port 131 are transported by a conveyor belt and are successively cleaned by an ultrasonic cleaner 209 and pre-dried by an air-drying device;

[0125] S3, The air-dried Chinese medicinal materials are transported to the transport platform 302. The transport platform 302 runs back and forth during the drying process of the first drying mechanism and the second drying mechanism until the drying is completed;

[0126] In S4, the dried Chinese medicinal materials are transported by the elevator 402, and the packaging mechanism heat-seals the sealed bag 416 and seals the Chinese medicinal materials.

[0127] The drying system of the present invention has the following technical effects

[0128] 1. Protect the integrity of the shape of Chinese medicinal materials

[0129] In the crushing part of this circulating drying system, a crushing unit is used to crush Chinese medicinal materials in a "hammering" manner. Through the irregular rotational movement of the hammer head 128 around the hammer shaft 127, the Chinese medicinal materials are hammered and crushed into a formed shape, abandoning the traditional rolling method, reducing the medicinal materials from becoming granular or powdery, and increasing the number of formed Chinese medicinal materials. Secondly, the transport table 302 in the flip-type drying device 300 moves reciprocally, and the first and second drying mechanisms perform convective drying on the transport table 302, which can not only increase the drying effect but also avoid mechanical damage caused by stirring, effectively protecting the shape of Chinese medicinal materials.

[0130] 2. Facilitate intuitive observation of the drying situation

[0131] The flip-type drying device 300 of the present invention can be flipped, and the operator can intuitively observe the state changes of Chinese medicinal materials during the drying process, such as color, texture, etc. Intuitive observation can help the operator timely discover possible problems during the drying process, such as excessive or insufficient local drying, and then timely adjust the drying parameters, judge whether the drying progress is normal, and can timely adjust the drying temperature or time to ensure the drying quality.

[0132] 3. Form a complete process system and realize process connection

[0133] This flip-type Chinese medicinal material circulating drying system forms an integrated process of crushing - drying - packaging, realizing the connection of each process step from feeding, drying to discharging. After drying, the packaging device 400 performs packaging, reducing manual intervention, lowering the labor intensity, and also ensuring the stability and consistency of product quality.

[0134] 4. The cleaning and air-drying device 200 performs cleaning and pre-air-drying

[0135] This cleaning and air-drying device 200 cleans Chinese medicinal materials, and at the same time separates the moisture in the Chinese medicinal materials containing aqueous solution. The moisture flows back from the first tabletop, and at the same time the air-drying device performs pre-drying treatment on the Chinese medicinal materials, shortening the drying time and also avoiding the direct drying of Chinese medicinal materials containing too much aqueous solution, resulting in a poor drying effect.

[0136] The working principle is as follows:

[0137] The traditional Chinese medicinal materials to be dried enter from the first feed inlet 106 and the second feed inlet 115 of the crushing device 100. On the way, they will first pass through the rolling round tube, so that the traditional Chinese medicinal materials are preliminarily crushed. Subsequently, the traditional Chinese medicinal materials enter the sieve plate of the crushing device 100. Under the combined action of the internal rotor disc 126 and the hammer head 128, the traditional Chinese medicinal materials are crushed. After crushing, they will pass through the sieve plate. Those that do not meet the conditions will continue to be crushed in the sieve plate until they meet the screening conditions. The traditional Chinese medicinal materials smaller than the sieve opening of the sieve plate will be sent to the conveyor belt 208 of the cleaning and air-drying device 200 through the discharge port 131. The crushing ratio refers to the original particle size D of the solid material max and the particle size d of the material after being crushed by the crushing device 100 or the pulverizer max The ratio, that is

[0138] D max / d max =i (1)

[0139] The ratio reflects the multiple of the reduction in particle size of the material after being crushed by the crushing device 100 once. The so-called crushing ratio usually refers to the average crushing ratio, that is, the average ratio of the particle sizes of the material before and after crushing and the degree of particle size change. Compared with drying large traditional Chinese medicinal materials, drying small medicinal materials is more efficient and convenient. For medicinal materials that do not need to be crushed, the medicinal materials can be directly skipped the crushing process step. In the crushing device 100, the medicinal materials are crushed by the comprehensive action of the impact of the hammer head 128, friction and the impact between traditional Chinese medicinal materials.

[0140] The second motor 214 works, and the conveyor belt 208 and the first heating tube 212 start to work. In this part of the structure, the conveying speed of the conveyor belt 208 is slower, aiming to better clean and pre-dry the traditional Chinese medicinal materials and transport the crushed traditional Chinese medicinal materials to the cleaning and air-drying device 200. Subsequently, the ultrasonic cleaner 209 works to ultrasonically clean the traditional Chinese medicinal materials. After cleaning, the traditional Chinese medicinal materials are transported to the air-drying area by the conveyor belt 208. When the traditional Chinese medicinal materials are transported into the air-drying cover 210, at this time, the first heating tube 212 has been fully preheated, and the first fan 211 works to pre-dry the traditional Chinese medicinal materials that have been cleaned. The purpose of pre-drying is to clean the water droplets remaining on the surface after cleaning the traditional Chinese medicinal materials and reduce the energy consumption in the next drying step. After pre-drying, the conveyor belt 208 transports the traditional Chinese medicinal materials to the next process.

[0141] During the cleaning process, the ultrasonic cleaner 209 converts the acoustic energy of the power ultrasonic frequency source into mechanical vibrations through the transducer. These vibrations are radiated into the cleaning liquid, forming countless tiny bubbles in the liquid. These bubbles grow rapidly and suddenly burst under the action of ultrasonic waves, generating a very strong impact force, thereby removing stains and impurities. For Chinese herbal medicines with different shapes, cleaning can be completed while retaining their shapes, and the cost of ultrasonic cleaning is relatively low. The power P of the transducer used this time is 50 W / 1 PCS, and the number N of vibrators is 24. Therefore, the total power W of the ultrasonic cleaner 209 总 can be obtained by multiplying the number N of transducers by the power of each transducer, that is:

[0142] W 总 = P × N (2)

[0143] W 总 = 24 × 50 W = 1200 W (3)

[0144] The third motor 313 starts, and the second heating wire begins to preheat. The Chinese herbal medicines are transported to the upper support plate 310. The support plate 310 makes a reciprocating motion along the first guide rail 306. At this time, the second fans 315 located on both sides of the support plate 310 start to work, and hot air is blown out from the first ventilation opening 322 and the second ventilation opening 320 to carry out delicate drying of the Chinese herbal medicines. During this period, the control panel on the control box 405 can monitor the drying situation in real time according to the temperature and humidity detection sensor, have a specific understanding of the temperature and humidity, and can also manually control the temperature and humidity standards. Subsequently, it can be opened from the locking frame to more specifically observe the internal situation.

[0145] Assume that G is the production capacity of the flip - type drying device 300, calculated based on the dried material containing the final moisture, with the unit of t / h, A is the evaporation intensity per unit volume, with the unit of kg / m 3 ³, V is the volume of the flip - type drying device 300, with the unit of m 3 ³, W1 is the initial moisture, W2 is the final moisture. Then the processing capacity of the flip - type drying device 300 can be calculated, that is:

[0146] G = AV / 100 × [(W1 - W2) / (100 - W1)] (4)

[0147] Assume that V is the waste gas volume of the flip - type drying device 300, with the unit of m 3 ³ / h, W is the water volume of the flip - type drying device 300, t is the amount of hot gas required for the flip - type drying device 300 to evaporate water; rw is the specific weight of water vapor. Then the waste gas volume generated when the flip - type drying device 300 dries the material can be calculated, that is:

[0148] V = W(t + 1 / rw) (5)

[0149] The dried Chinese medicinal materials move along the first guide rail 306 and fall into the hopper 404. The elevator 402 connected to the hopper 404 lifts the Chinese medicinal materials to a certain height, and then the Chinese medicinal materials fall into the inclined collecting plate 407. The sealing bag 416 moves downward along the outer wall of the slideway 415, and the guide disc group 420 rolls over the sealing bag 416 to make the edges of the sealing bag 416 overlap. The heating disc group 419 heats the edges of the sealing bag 416 on the path, and then the lower guide disc group 420 presses and combines the heated edges of the sealing bag 416. At this time, the cylindrical sealing bag 416 is formed.

[0150] After the initial sealing bag 416 passes through the tray 437, the packing mechanism starts to work. The first support 422 rotates to drive the second fixed block 424 to slide, and the second sliding block drives the heat-sealing module 426 to seal the sealing bag 416 in the middle. Then the heat-sealing module 426 is released. At this time, under the action of gravity, the Chinese medicinal materials fall into the sealing bag 416 through the blanking channel 414. Then the sealing bag 416 continues to move downward for a certain distance and stops. The heat-sealing module 426 heat-seals the sealing bag 416 again. The fourth support 435 pushes the third fixed block 430 to run, so that the fifth fixed block 433 clamps, and the cutter group 434 cuts and separates the part above the seal. Then the heat-sealing module 426 is released and the cutter group 434 is opened. Then the above operations are repeated. The packing speed of the packing device 400 is 30 - 60 bags per minute, and its metering range is 1 - 1500 grams per milliliter.

[0151] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
