Description

Technical Field

[0001] This invention relates to the field of konjac processing equipment technology, and in particular to a grinding device for konjac processing. Background Technology

[0002] Konjac, a perennial herbaceous plant of the Cucurbitaceae family, is mainly distributed in Asian countries such as China and Japan. The main active ingredient in konjac is glucomannan. Konjac is rich in carbohydrates, low in calories, and has a higher protein content than potatoes and sweet potatoes. It is also rich in trace elements, including vitamins A and B. In particular, it is rich in glucomannan, which has the effects of weight loss, lowering blood pressure, lowering blood sugar, detoxification and bowel movement, cancer prevention and calcium supplementation. It also has multiple physiological functions such as water absorption and swelling, lowering blood sugar and cholesterol. Due to its low-calorie and high-fiber characteristics, konjac has been widely used in the food industry in recent years, especially in the fields of health foods and weight loss foods.

[0003] With the continuous expansion of the konjac product market, the requirements for konjac processing technology are also becoming increasingly stringent. Konjac grinding is a crucial step in the deep processing of konjac. The design and optimization of konjac grinding equipment directly affect the quality and yield of konjac flour, which in turn influences the quality of downstream products. Traditional konjac grinding methods suffer from low efficiency, high energy consumption, and uneven grinding, failing to meet the demands of modern konjac processing.

[0004] Chinese Patent Publication No. CN119368307A discloses a grinding device and process for konjac processing. The device includes a hollow processing cylinder with a feeding funnel connected to it. A guiding unit and a grinding unit are installed inside both the processing cylinder and the feeding funnel. The device drives a grinding block to rotate and contact the inner wall of the processing cylinder. The relative rotation between the grinding block and the inner wall of the processing cylinder causes the konjac particles trapped between them to shift. Simultaneously, the shifted konjac particles rub against the grinding block and the processing cylinder, thus achieving the grinding effect. The ground konjac is then conveyed downwards. While grinding konjac granules, the larger konjac granules are ground again, avoiding the need to repeatedly feed the larger konjac granules back into the equipment for multiple grinding cycles. This improves both the grinding effect and the production efficiency of konjac grinding. However, in actual use, although the device is equipped with a crushing component, it lacks an efficient reflux mechanism for insufficiently crushed materials. Some coarse materials are only crushed again by gravity, which easily leads to "crushing dead zones" and a high proportion of coarse materials. This requires manual sorting and rework, which not only increases labor intensity but also reduces overall production efficiency. Summary of the Invention

[0005] The main objective of this invention is to provide a grinding device and process for konjac processing, which can effectively solve the problem of lacking an efficient reflux driving mechanism for insufficiently ground materials. Some coarse materials are only ground again by gravity, which easily leads to "grinding dead zones".

[0011] Preferably, the screening component includes a screening cylinder, which is fixedly installed on the outer side of the inner cavity of the mounting shell. The screening cylinder has a feed inlet on the side near the hopper. The inner cavity of the screening cylinder communicates with the inner cavity of the feed frame at the top of the mounting shell. Fixing plates are provided on both sides of the inner surface of the feed inlet, and the outer surfaces of the two fixing plates are fixedly connected to the inner cavity surface of the mounting shell.

[0012] Preferably, the pushing component includes a rotating ring one and a rotating ring two, both of which are rotatably mounted on the inner surface of the mounting shell. The outer surface of the rotating ring two is rotatably connected to the outer surfaces of two fixed plates. Multiple threaded plates are provided between the rotating ring one and the rotating ring two. A connecting member is provided on the side of the outer surface of the rotating ring one away from the rotating ring two.

[0013] Preferably, the conveying device includes a mounting frame, which is fixedly mounted on the outer surface of the mounting bracket. The lower part of the inner cavity of the mounting frame communicates with the inner cavity of the mounting shell. A belt toothed ring is slidably mounted on the inner surface of the mounting frame. Multiple lifting plates are provided on the inner surface of the belt toothed ring. A gear three is provided on the upper part of the inner cavity of the mounting frame. The gear three meshes with the belt toothed ring. The outer surface of the gear three is fixedly connected to the inner wall of the pulley on the upper part of the driven device. A guide frame is provided on the upper part of the mounting frame. The inner cavity of the guide frame communicates with the inner cavity of the mounting frame and also communicates with the inner cavity of the discharge hopper.

[0014] The present invention also discloses a production process using the above-mentioned konjac processing grinding device, the specific steps of which are as follows: S1. Raw material pretreatment and feeding After the konjac raw material is pre-treated by washing, peeling, slicing, drying or screening to remove impurities, the pre-treated konjac raw material is fed into the inner cavity of the installation cylinder from the feeding hopper of the crushing unit by the staff or the conveying unit to complete the initial feeding of the raw material. S2, Primary crushing and preliminary screening The transmission device is started, which drives the crushing roller of the crushing component to rotate through the belt pulley. The crushing roller crushes the konjac in the inner cavity of the mounting cylinder. At the same time, the crushing roller drives the mounting ring two to rotate through the meshing of gear one and gear two and gear ring one. The mounting ring two drives the mounting ring one and multiple push plates to rotate synchronously through the connecting rod one.

[0015] During the crushing process, the screening mechanism at the bottom of the inner cavity of the installation cylinder performs preliminary screening of the crushed konjac blocks: materials that meet the preliminary particle size requirements fall to the subsequent screening device, while konjac blocks that do not pass through the screening screen are pushed upward by the push plate that rotates with the installation ring. When the push plate rotates to the upper part of the inner cavity of the installation cylinder, the konjac blocks fall under the action of gravity and are crushed again by the crushing roller.

[0016] During this process, the installation ring one drives the vibrating ring to rotate synchronously, and the concave and convex surfaces of the vibrating ring push the vibrating wheel to move up and down, which in turn drives the screening screen to generate high-frequency vibration under the action of the elastic telescopic rod through the connecting rod two, thereby improving the initial screening efficiency; S3, Secondary sieving and collection of qualified powder After initial screening, the konjac powder enters the inner cavity of the screening cylinder of the screening device through the connection frame and the upper feed frame of the mounting shell. The conveying device drives the conical screw to rotate synchronously, and the conical screw pushes the konjac powder to the side closer to the conveying device. The screening cylinder performs secondary screening of the powder.

[0017] Konjac powder that meets the particle size requirements passes through the filter holes on the surface of the screening cylinder and enters the inner cavity of the mounting shell. Some powder falls directly into the inner cavity of the collection box through the feed hopper. The qualified powder that falls into the inner cavity of the mounting shell near the conveying device is processed by the pusher driven by the conical screw through the connecting part. The rotating ring one drives the threaded plate and the rotating ring two to rotate, guiding the qualified powder on this side to the feed hopper, and finally conveying it to the collection box to complete the collection.

[0018] The fixing plate prevents powder that has not undergone secondary screening from directly entering the collection box, ensuring the purity of the finished product. The long cylindrical structure of the screening cylinder increases the screening contact area, further improving screening efficiency. S4. Non-conforming materials are returned for re-grinding. Unqualified konjac blocks that fail to pass through the screening cylinder during the secondary screening are pushed out from the outlet near the conveying device by the conical screw and introduced into the mounting frame cavity of the conveying device.

[0019] The crushing roller drives the gear three to rotate through the driven device. The gear three meshes with the belt tooth ring and drives it to rotate. The lifting plate on the surface of the belt tooth ring rotates with it, pushing the unqualified konjac blocks in the inner cavity of the mounting frame upwards. They are then sent back to the discharge hopper of the crushing component through the guide frame and re-enter the inner cavity of the mounting cylinder for crushing, thus realizing the recycling of unqualified materials. S5, Full-process kinetic energy transfer and monitoring Throughout the production process, the transmission device provides kinetic energy to the crushing roller and the conical screw, while the driven device realizes the kinetic energy transfer between the crushing roller and the conveying device, ensuring that all components operate synchronously and in coordination, and monitoring the crushing roller speed, the vibration frequency of the screening screen and the material flow direction in real time to ensure process stability.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the pulverizing component of the device is linked with the pulverizing roller: when the pulverizing roller rotates, it drives the mounting ring and the push plate to rotate through gear transmission, which can push the konjac blocks that have not passed the initial screening by the screening mechanism to the upper part of the mounting cylinder, so that they fall under the action of gravity and are pulverized again by the pulverizing roller. This circulating pulverizing structure avoids the problem of "discharge due to insufficient pulverization in one step" in traditional equipment, greatly improves the thoroughness of konjac pulverization and reduces the waste of coarse materials.

[0021] In this invention, on the one hand, the screening mechanism utilizes the cooperation of a vibrating ring and a vibrating wheel to achieve high-frequency vibration of the screening screen, effectively preventing powder from clogging the screen holes and improving the initial screening efficiency. On the other hand, the screening device uses a long cylindrical screening cylinder, which increases the screening contact area, and the conical screw can avoid accumulation when pushing the powder, further improving the secondary screening efficiency. At the same time, through two screenings, the uniformity of the particle size of the finished konjac flour is ensured.

[0022] In this invention, the conveying device, crushing component, and screening device form a closed loop: unqualified konjac blocks that fail to pass the secondary screening by the screening device are returned to the discharge hopper by the conveying device and re-enter the crushing component. This automatic return design requires no manual intervention, allowing unqualified materials to be recycled and reprocessed, thereby improving material utilization. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] Example 1 like Figure 1 and Figure 2 As shown, this embodiment discloses a grinding device for konjac processing, including a mounting frame 1. A crushing component 2 is provided on the upper part of the mounting frame 1, and a sieving device 4 is fixedly installed in the middle of the inner cavity of the mounting frame 1 on the lower part of the crushing component 2. A transfer device 3 is provided on the lower part of the mounting frame 1, and the transfer device 3 is used to transfer kinetic energy to the crushing component 2 and the sieving device 4.

[0027] Specifically, in the konjac crushing process, the workers put the pre-treated konjac raw material into the inner cavity of the crushing component 2. Then the transfer device 3 is started and drives the crushing component 2 to run, crushing the konjac raw material. After the konjac is crushed to the preset particle size by the crushing component 2, the konjac powder will enter the inner cavity of the screening device 4 for secondary screening.

[0028] In order to crush konjac, such as Figure 3 and Figure 4 As shown, the crushing component 2 includes a mounting cylinder 21, which is fixedly mounted on the upper part of the mounting frame 1. A feeding hopper 22 is provided on the upper part of the mounting cylinder 21. A crushing roller 23 is rotatably mounted in the middle of the inner cavity of the mounting cylinder 21. One side of the outer surface of the crushing roller 23 is fixedly connected to the inner wall of the pulley on the upper part of the transmission device 3, and the other side of the outer surface of the crushing roller 23 is fixedly connected to the inner wall of the pulley on the lower part of the driven device 7. A gear is provided on the side of the outer surface of the crushing roller 23 near the transmission device 3. A pushing mechanism 24 is provided outside the inner cavity of the mounting cylinder 21, and a screening mechanism 25 is provided at the lower part of the inner cavity of the mounting cylinder 21.

[0029] Specifically, in the process of crushing the pre-treated konjac, the workers or the corresponding conveying unit put the treated konjac into the inner cavity of the installation cylinder 21 from the feeding hopper 22. During this process, the conveying device 3 drives the crushing roller 23 to rotate, and the crushing roller 23 crushes the konjac in the inner cavity of the installation cylinder 21 when it rotates.

[0030] Furthermore, during the konjac crushing process of the crushing roller 23 into the inner cavity of the mounting cylinder 21, the screening mechanism 25 performs preliminary screening of the crushed konjac blocks. During the screening operation, the pushing mechanism 24 can push the konjac blocks that fail the screening upwards so that they are crushed again by the crushing roller 23.

[0031] In order to further pulverize fragments that have not been pulverized to a certain degree, such as... Figure 5 and Figure 6As shown, the pushing mechanism 24 includes two mounting rings 241, which are rotatably mounted on both sides of the outer surface of the crushing roller 23. Multiple pushing plates 242 are arranged between the two mounting rings 241. Multiple connecting rods 243 are arranged on the side of the outer surface of the two mounting rings 241 that are far apart from each other. Mounting rings 244 are rotatably mounted on the inner surface of the mounting cylinder 21 at the middle of the outer surface of the connecting rods 243 on both sides. A toothed ring 2441 is arranged on the inner surface of the mounting ring 2441 that is close to the transmission device 3. A gear 245 is meshed on the inner side of the toothed ring 2441. The gears 245 are rotatably mounted on the inner surface of the mounting cylinder 21. The gears 245 mesh with the gears on the outer surface of the crushing roller 23. A vibrating ring 246 is arranged in the middle of the side of the outer surface of the two mounting rings 241 that are far apart from each other.

[0032] Specifically, when the crushing roller 23 rotates, the mounting ring 244 rotates through the cooperation of gear 1 and gear 245 and gear ring 2441 on one side of its surface. When the mounting ring 244 rotates, it drives the corresponding mounting ring 241 to rotate synchronously through multiple connecting rods 243. The rotation of the mounting ring 241 in turn drives multiple push plates 242 to rotate.

[0033] Furthermore, during the konjac crushing process by the crushing roller 23, konjac blocks that do not pass the screening mechanism 25 will be pushed upward by the push plate 242 that rotates with the mounting ring 241. When a single push plate 242 rotates to the upper part of the inner cavity of the mounting cylinder 21, the pushed konjac blocks fall under their own gravity and are crushed again by the crushing roller 23 during this process.

[0034] In order to screen the pulverized konjac powder and, at the same time, speed up the screening process, such as... Figure 6 As shown, the screening mechanism 25 includes a connecting frame 251, which is fixedly installed on the lower part of the outer surface of the mounting cylinder 21. The inner cavity of the connecting frame 251 communicates with the inner cavity of the mounting cylinder 21. A screening screen 252 is provided on the upper part of the inner cavity of the connecting frame 251. The screening screen 252 is adapted to multiple push plates 242. Elastic telescopic rods 253 are provided at the four corners of the lower surface of the screening screen 252 and are fixedly installed on the inner surface of the connecting frame 251. Connecting rods 254 are provided on both sides of the middle part of the outer surface of the screening screen 252. Both connecting rods 254 extend to the outside of the connecting frame 251. Vibrating wheels 255 are provided on the side of the outer surface of the two connecting rods 254 that are far apart from each other. The two vibrating wheels 255 are adapted to two vibrating rings 246 respectively.

[0035] Specifically, when the two mounting rings 241 rotate, they drive the two vibrating rings 246 to rotate synchronously. Since the outer surface of the vibrating rings 246 has an uneven structure, when the two vibrating rings 246 rotate, their uneven structure first pushes the two vibrating wheels 255 downward, which in turn causes the two vibrating wheels 255 to drive the screening screen 252 downward through the two connecting rods 254. During the downward movement of the screening screen 252, the four elastic telescopic rods 253 are compressed. When the two vibrating wheels 255 contact the concave surface of the outer surface of the vibrating rings 246, the four elastic telescopic rods 253 push the screening screen 252 back to the initial position.

[0036] Furthermore, because the crushing roller 23 rotates at a relatively high speed, the rotation speed of the vibrating ring 246 increases synchronously. When the vibrating ring 246 rotates, the sieve screen 252 vibrates through the transmission action of the vibrating wheel 255 and the connecting rod 254, thereby effectively improving the screening efficiency in the screening process of konjac powder by the sieve screen 252.

[0037] Example 2 This embodiment further improves the screening device 4 based on Embodiment 1, such as... Figure 1 and Figure 2 As shown, a conveying device 5 is provided on the side of the middle of the mounting frame 1 away from the crushing component 2. A driven device 7 for transmitting kinetic energy is provided on the side of the outer surface of the conveying device 5 away from the crushing component 2. The lower part of the driven device 7 is fixedly connected to one side of the outer surface of the crushing component 2. A collection box 6 is provided in the lower part of the inner cavity of the mounting frame 1.

[0038] Specifically, after the konjac is crushed by the crushing component 2, the konjac powder enters the inner cavity of the screening device 4 for secondary screening. The qualified konjac powder is transported to the inner cavity of the collection box 6 for collection, while the unqualified konjac blocks are poured into the inner cavity of the conveying device 5 and sent back to the inner cavity of the crushing component 2 for further crushing.

[0039] In order to perform a second sieving of the pulverized konjac powder, such as Figure 7 and Figure 8 As shown, the screening device 4 includes a mounting shell 41, which is fixedly installed in the middle of the mounting frame 1. A conical screw 44 is provided in the middle of the inner cavity of the mounting shell 41. The outer surface of the conical screw 44 is fixedly connected to the inner belt gear in the middle of the transmission device 3. A screening component 42 is provided on the outer side of the inner cavity of the mounting shell 41 and sleeved on the outer surface of the conical screw 44. A pushing component 43 is provided on the outer surface of the screening component 42. The side of the outer surface of the pushing component 43 away from the crushing component 2 is fixedly connected to the outer surface of the conical screw 44. A hopper 45 is provided on the side of the outer surface of the mounting shell 41 close to the transmission device 3. A feeding frame is provided on the side of the outer surface of the mounting shell 41 away from the transmission device 3. A feeding frame is provided on the upper part of the outer surface of the mounting shell 41. The feeding frame is adapted to the connecting frame 251.

[0040] Specifically, during the rotation of the crushing component 2 driven by the conveying device 3, the conical screw 44 is simultaneously rotated. When the konjac powder in the inner cavity of the crushing component 2 falls into the inner cavity of the screening component 42, the screening component 42 performs secondary screening of the konjac powder. At the same time, the conical screw 44 rotates and pushes the konjac powder towards the side closer to the conveying device 5. During this process, qualified konjac powder passes through the filter holes on the screening component 42 and enters the inner cavity of the mounting shell 41. The movement of the konjac powder by the conical screw 44 can prevent powder accumulation and effectively improve the screening efficiency of the screening component 42.

[0041] Furthermore, during the sieving process of konjac powder, the qualified konjac powder sieved out by the sieving component 42 can be directly collected by falling into the inner cavity of the collection box 6 through the feed hopper 45, or pushed to the inner cavity of the feed hopper 45 by the pusher 43 and then falling into the inner cavity of the collection box 6 to complete the collection.

[0042] In order to perform secondary sieving of konjac powder, such as Figure 8 As shown, the screening component 42 includes a screening cylinder 421, which is fixedly installed on the outer side of the inner cavity of the mounting shell 41. The screening cylinder 421 has a feed inlet 422 on the side near the hopper 45. The inner cavity of the screening cylinder 421 is connected to the inner cavity of the feed frame at the top of the mounting shell 41. Fixing plates 423 are provided on both sides of the inner surface of the feed inlet 422. The outer surfaces of the two fixing plates 423 are fixedly connected to the inner cavity surface of the mounting shell 41.

[0043] Specifically, the surface of the screening cylinder 421 is provided with multiple filter holes, and konjac powder that meets the particle size requirements can pass through the filter holes. The fixing plate 423 is fixedly connected to the inner cavity surface of the mounting shell 41, which allows the konjac powder discharged from the inner cavity of the crushing component 2 to directly enter the inner cavity of the screening cylinder 421 through the feed inlet 422, avoiding the konjac powder that has not been screened twice by the screening device 4 from directly entering the inner cavity of the collection box 6 through the mounting shell 41.

[0044] Furthermore, the screening cylinder 421 has an approximately elongated cylindrical structure, which increases the screening contact area and thus improves screening efficiency.

[0045] In order to push the screened konjac powder into the lower hopper 45, and then allow the qualified konjac powder to enter the inner cavity of the collection box 6 for storage, such as... Figure 9As shown, the pusher 43 includes a first rotating ring 431 and a second rotating ring 432. Both the first rotating ring 431 and the second rotating ring 432 are rotatably mounted on the inner surface of the mounting shell 41. The outer surface of the second rotating ring 432 is rotatably connected to the outer surfaces of the two fixing plates 423. A plurality of threaded plates 434 are provided between the first rotating ring 431 and the second rotating ring 432. A connector 433 is provided on the side of the outer surface of the first rotating ring 431 away from the second rotating ring 432. The inner surface of the connector 433 is fixedly connected to the outer surface of the tapered screw 44.

[0046] Specifically, during the rotation of the conical screw 44 driven by the conveying device 3, the konjac powder in the inner cavity of the screening component 42 is gradually screened by the screening cylinder 421. During this process, some of the konjac powder falls to the side of the inner cavity of the mounting shell 41 near the conveying device 5. At this time, the conical screw 44 drives the pushing component 43 to rotate, pouring the qualified konjac powder on this side into the inner cavity of the feeding hopper 45, and then conveying it to the inner cavity of the collection box 6 for collection.

[0047] Furthermore, when the conical screw 44 rotates, it drives the rotating ring 431 to rotate through the connector 433. The rotating ring 431 then drives multiple threaded plates 434 to rotate synchronously with the rotating ring 432. During the rotation of the multiple threaded plates 434, the rotating ring 432 can guide the qualified konjac powder that has entered the inner cavity of the mounting shell 41 to the hopper 45.

[0048] In order to transport the substandard konjac blocks screened out by the screening device 4 to the inner cavity of the crushing component 2 for re-crushing, such as... Figure 10 and Figure 11 As shown, the conveying device 5 includes a mounting frame 51, which is fixedly mounted on the outer surface of the mounting frame 1. The lower part of the inner cavity of the mounting frame 51 communicates with the inner cavity of the mounting shell 41. A belt toothed ring 52 is slidably mounted on the inner surface of the mounting frame 51. Multiple lifting plates 521 are provided on the inner surface of the belt toothed ring 52. A gear 53 is provided on the upper part of the inner cavity of the mounting frame 51. The gear 53 meshes with the belt toothed ring 52. The outer surface of the gear 53 is fixedly connected to the inner wall of the pulley on the upper part of the driven device 7. A guide frame 54 is provided on the upper part of the mounting frame 51. The inner cavity of the guide frame 54 communicates with the inner cavity of the mounting frame 51 and also communicates with the inner cavity of the discharge hopper 22.

[0049] Specifically, when the screening device 4 performs secondary screening on the konjac powder discharged from the inner cavity of the crushing component 2, the konjac blocks that fail to pass the screening are pushed out by the conical screw 44 from the outlet of the inner cavity of the screening component 42 near the conveying device 5, and the pushed-out konjac blocks are introduced into the inner cavity of the mounting frame 51.

[0050] Furthermore, during the rotation of the crushing roller 23, the belt toothed ring 52 is driven to rotate through the cooperation of the driven device 7 and the gear 3 53. Therefore, after the konjac blocks that have not passed the screening device 4 enter the inner cavity of the mounting frame 51, the multiple lifting plates 521 on the surface of the belt toothed ring 52 push the unqualified konjac blocks that have been introduced into the inner cavity of the mounting frame 51 upward as the belt toothed ring 52 rotates, so that they are sent back to the inner cavity of the crushing component 2 through the guide frame 54 for crushing again.

[0051] Example 3: This application also discloses a production process for a konjac grinding device, the specific steps of which are as follows: S1. Raw material pretreatment and feeding After the konjac raw material is pre-treated by washing, peeling, slicing, drying fresh konjac or screening and removing impurities from dried konjac slices, the pre-treated konjac raw material is fed into the inner cavity of the installation cylinder 21 from the feeding hopper 22 of the crushing unit 2 by the staff or the conveying unit to complete the initial feeding of the raw material. S2, Primary crushing and preliminary screening The transmission device 3 is started, which drives the crushing roller 23 of the crushing component 2 to rotate through the belt pulley. The crushing roller 23 crushes the konjac in the inner cavity of the mounting cylinder 21. At the same time, the crushing roller 23 drives the mounting ring 244 to rotate through the meshing of gear 1 and gear 245 and gear ring 1 2441. The mounting ring 244 drives the mounting ring 1 241 and multiple push plates 242 to rotate synchronously through the connecting rod 1 243.

[0052] During the crushing process, the screening mechanism 25 at the lower part of the inner cavity of the mounting cylinder 21 performs preliminary screening of the crushed konjac blocks: materials that meet the preliminary particle size requirements fall to the subsequent screening device 4, and konjac blocks that do not pass through the screening screen 252 are pushed upward by the push plate 242 that rotates with the mounting ring 241. When the push plate 242 rotates to the upper part of the inner cavity of the mounting cylinder 21, the konjac blocks fall under the action of gravity and are crushed again by the crushing roller 23.

[0053] During this process, the installation ring 241 drives the vibrating ring 246 to rotate synchronously. The concave and convex surfaces of the vibrating ring 246 push the vibrating wheel 255 to move up and down, which in turn drives the screening screen 252 to generate high-frequency vibration under the action of the elastic telescopic rod 253 through the connecting rod 254, thereby improving the initial screening efficiency. S3, Secondary sieving and collection of qualified powder After initial screening, the konjac powder enters the inner cavity of the screening cylinder 421 of the screening device 4 through the cooperation of the connecting frame 251 and the upper feed frame of the mounting shell 41. The conveying device 3 drives the conical screw 44 to rotate synchronously, and the conical screw 44 pushes the konjac powder to the side closer to the conveying device 5. The screening cylinder 421 performs secondary screening of the powder.

[0054] Konjac powder that meets the particle size requirements passes through the filter holes on the surface of the screening cylinder 421 and enters the inner cavity of the mounting shell 41. Some powder falls directly into the inner cavity of the collection box 6 via the feed hopper 45 for collection. The qualified powder that falls into the inner cavity of the mounting shell 41 near the conveying device 5 is processed by the pusher 43 driven by the conical screw 44 through the connector 433. The rotating ring 431 drives the threaded plate 434 and the rotating ring 432 to rotate, guiding the qualified powder on this side to the feed hopper 45, and finally conveying it to the collection box 6 to complete the collection.

[0055] The fixing plate 423 can prevent powder that has not undergone secondary screening from directly entering the collection box 6, ensuring the purity of the finished product. The long cylindrical structure of the screening cylinder 421 increases the screening contact area and further improves the screening efficiency. S4. Non-conforming materials are returned for re-grinding. Unqualified konjac blocks that fail to pass through the screening cylinder 421 during the secondary screening are pushed out from the outlet of the inner cavity of the screening component 42 near the conveying device 5 by the conical screw 44 and introduced into the inner cavity of the mounting frame 51 of the conveying device 5.

[0056] The crushing roller 23 drives the gear 3 53 to rotate through the driven device 7. The gear 3 53 meshes with the belt toothed ring 52 and drives it to rotate. The lifting plate 521 on the surface of the belt toothed ring 52 rotates with it, pushing the unqualified konjac blocks in the inner cavity of the mounting frame 51 upwards. They are then sent back to the discharge hopper 22 of the crushing component 2 through the guide frame 54 and re-enter the inner cavity of the mounting cylinder 21 for crushing, thus realizing the recycling of unqualified materials. S5, Full-process power transfer and monitoring Throughout the production process, the transfer device 3 provides kinetic energy to the crushing roller 23 and the conical screw 44, and the driven device 7 realizes the kinetic energy transfer between the crushing roller 23 and the conveying device 5, ensuring that all components operate synchronously and in coordination, and monitoring the speed of the crushing roller, the vibration frequency of the screening screen and the material flow direction in real time to ensure process stability.

Raw material pretreatment and feeding After the konjac raw material is pre-treated by washing, peeling, slicing, drying (fresh konjac) or screening to remove impurities (dried konjac slices), the pre-treated konjac raw material is fed into the inner cavity of the installation cylinder (21) from the feeding hopper (22) of the crushing component (2) by the staff or the conveying unit to complete the initial feeding of the raw material; S2, Primary crushing and preliminary screening Start the transfer device (3), which drives the crushing roller (23) of the crushing component (2) to rotate through the belt pulley. The crushing roller (23) crushes the konjac in the inner cavity of the mounting cylinder (21). At the same time, the crushing roller (23) drives the mounting ring (244) to rotate through the meshing of gear one and gear two (245) and gear ring one (2441). The mounting ring two (244) drives the mounting ring one (241) and multiple push plates (242) to rotate synchronously through the connecting rod one (243). During the crushing process, the screening mechanism (25) at the bottom of the inner cavity of the installation cylinder (21) performs preliminary screening on the crushed konjac blocks: the material that meets the preliminary particle size requirements falls to the subsequent screening device (4), and the konjac blocks that do not pass the screening screen (252) are pushed upward by the push plate (242) that rotates with the installation ring (241). When the push plate (242) rotates to the upper part of the inner cavity of the installation cylinder (21), the konjac blocks fall under the action of gravity and are crushed again by the crushing roller (23); During this process, the installation ring (241) drives the vibrating ring (246) to rotate synchronously. The concave and convex surfaces of the vibrating ring (246) push the vibrating wheel (255) to move up and down, and then through the connecting rod (254), the screening screen (252) generates high-frequency vibration under the action of the elastic telescopic rod (253), thereby improving the initial screening efficiency. S3, Secondary sieving and collection of qualified powder After preliminary screening, the konjac powder enters the inner cavity of the screening cylinder (421) of the screening device (4) through the cooperation of the connecting frame (251) and the upper feed frame of the mounting shell (41). The transfer device (3) drives the conical screw (44) to rotate synchronously. The conical screw (44) pushes the konjac powder to the side closer to the conveying device (5). The screening cylinder (421) performs secondary screening on the powder. Konjac powder that meets the particle size requirements passes through the filter holes on the surface of the screening cylinder (421) and enters the inner cavity of the mounting shell (41). Some powder falls directly into the inner cavity of the collection box (6) through the feed hopper (45) for collection. The qualified powder that falls into the inner cavity of the mounting shell (41) near the conveying device (5) is processed by the pusher (43) driven by the conical screw (44) through the connector (433). The rotating ring one (431) drives the threaded plate (434) and the rotating ring two (432) to rotate, guiding the qualified powder on this side to the feed hopper (45) and finally conveying it to the collection box (6) to complete the collection. The fixing plate (423) can prevent powder that has not undergone secondary screening from directly entering the collection box (6) to ensure the purity of the finished product. The long cylindrical structure of the screening cylinder (421) increases the screening contact area and further improves the screening efficiency. S4. Non-conforming materials are returned for re-grinding. Unqualified konjac blocks that fail to pass through the screening cylinder (421) during secondary screening are pushed out from the outlet of the screening component (42) near the conveying device (5) by the conical screw (44) and introduced into the inner cavity of the mounting frame (51) of the conveying device (5); The crushing roller (23) drives the gear three (53) to rotate through the driven device (7). The gear three (53) meshes with the belt toothed ring (52) and drives it to rotate. The lifting plate (521) on the surface of the belt toothed ring (52) rotates with it, pushing the unqualified konjac blocks in the inner cavity of the mounting frame (51) upward. They are then sent back to the discharge hopper (22) of the crushing component (2) through the guide frame (54) and re-enter the inner cavity of the mounting cylinder (21) for crushing operations, thus realizing the recycling of unqualified materials. S5, Full-process kinetic energy transfer and monitoring Throughout the production process, the transfer device (3) provides kinetic energy to the crushing roller (23) and the conical screw (44), and the driven device (7) realizes the kinetic energy transfer between the crushing roller (23) and the conveying device (5), ensuring that all components operate synchronously and collaboratively, and monitoring the speed of the crushing roller, the vibration frequency of the screening screen and the material flow direction in real time to ensure process stability.
