Description

Technical Field

[0001] The present invention relates to the field of granulation equipment, and particularly to a granulation equipment and method for traditional Chinese medicine extracts and natural molecular small particles capsules. Background Art

[0002] When preparing capsule products from traditional Chinese medicine extracts and natural molecular small particles, it is usually necessary to process the mixed powder mass into uniform particles through a wet granulation process to ensure the stability of subsequent capsule filling, drying, and storage processes. Most of the existing granulation equipment adopts a single structure of stirring - extrusion. Before the material enters the granulation area, there are often problems such as insufficient pretreatment, including insufficient dispersion of the powder mass and inability to clean the residual material adhering to the inner wall of the processing cylinder in a timely manner. As a result, the material is unevenly stressed during the granulation process, the particle size is unstable, and even blockage and agglomeration occur, affecting the granulation quality. In addition, some equipment lacks necessary on - line wetting or auxiliary cleaning structures during the material processing process, resulting in the accumulation of material residues, causing a risk of cross - contamination, increasing the workload of manual equipment cleaning, and reducing production continuity. Therefore, there is an urgent need for a comprehensive granulation equipment with on - line scraping, automatic dispersion, auxiliary wetting, and linkage with the granulation mechanism to improve the granulation efficiency and particle consistency of traditional Chinese medicine extracts and natural molecular small particles. Summary of the Invention

[0003] Therefore, to address the above deficiencies, the present invention provides a granulation equipment and method for traditional Chinese medicine extracts and natural molecular small particles capsules.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A granulation equipment for traditional Chinese medicine extracts and natural molecular small particles capsules includes a transmission box for transmission. At the left end of the top of the transmission box, a processing cylinder is installed. At the lower left end of the processing cylinder, a granule outlet is provided. At the left end of the top of the processing cylinder, a first motor is installed. In the middle of the top of the processing cylinder, a connecting pipe is provided. The right end of the top of the processing cylinder is a top cover. At the right end of the top of the transmission box, a second motor connecting the internal transmission components of the transmission box is installed. Inside the upper end of the processing cylinder, a scraping device is provided, which can scrape the excess material adhering to the upper inner side of the processing cylinder, and can also perform cleaning and material dispersion. Inside the lower end of the processing cylinder, an extrusion roller is provided, and the bottom of the extrusion roller contacts the granulation disk.

[0005] Preferably, the output shaft at the bottom of the first motor passes through the processing cylinder and is connected to a driving wheel, and the outside of the driving wheel is connected to the upper end of the scraping device through a synchronous belt.

[0006] Preferably, the scraping device includes a connecting block connected to the top of the treatment cylinder, a rotating component located below the connecting block, a driven wheel located at the upper inner end of the rotating component and connected to the synchronous belt on the outer side, an elastic plate located on the right side of the rotating component, a scraping blade installed on the right side of the elastic plate and in contact with the inner side of the treatment cylinder, a guide component located in the middle of the rotating component, a water guide component located at the top of the rotating component, a connecting component installed at the bottom of the rotating component, a dispersing net located at the bottom of the connecting component, two sets of sliding components located inside the guide component, a connecting disc hinged to the bottom of the two sets of sliding components, a linkage shaft located at the bottom of the connecting disc, and a fixing column fixed to the top of the guide component and located inside the connecting block. The upper inner end of the fixing column is connected to the connecting pipe, and the bottom of the linkage shaft passes through the rotating component and is connected to the connecting component.

[0007] Preferably, the rotating component is C-shaped.

[0008] Preferably, the elastic sheet has elasticity and can be deformed and bent.

[0009] Preferably, the two ends of the scraping blade are chamfered, and the outer side is arc-shaped.

[0010] Preferably, the lower end of the guide member is provided with a cross-shaped guide groove, and two sets of opposing sliding members are movably embedded inside the guide groove.

[0011] Preferably, the fixing column and the water guide are provided with a communicating water tank, and the upper end of the water tank is connected to the connecting pipe.

[0012] Preferably, the water guide is provided with a spray hole on the outer side, and a partition net is fixed inside the spray hole.

[0013] Preferably, the specific steps are as follows:

[0014] S1 Weigh the powdered Chinese herbal extract and the excipients required for natural molecular particles separately, add them to the mixing container in proportion, and stir manually or mechanically to ensure that the raw materials are fully mixed and uniform.

[0015] S2 opens the top cover of the equipment, puts the prepared powder into the processing cylinder, and then closes the top cover to prepare for granulation processing;

[0016] S3 starts the first motor, causing the drive wheel to drive the synchronous belt and driven wheel to rotate. The driven wheel further drives the rotating parts to achieve circular motion. Under the drive of the rotating parts: the elastic plate pushes the scraper to stick to the inner wall of the processing cylinder to scrape and clean the attached material. The chamfer and arc surface structure of the scraper disperses the material during rotation. The linkage shaft drives the connecting plate and the dispersing net to make elliptical circular motion, further dispersing the falling material and improving the uniformity of feeding.

[0017] After being dispersed, the material falls onto the granulation disc at the bottom of the processing cylinder. The second motor is started to rotate the granulation disc and cooperate with the upper extrusion roller to extrude the material into cylindrical or spherical particles.

[0018] After the material is extruded and formed, it is automatically discharged through the lower granulation hopper, and the resulting granules are collected, thus completing the granulation step.

[0019] The beneficial effects of this invention are:

[0020] This invention utilizes a synchronously driven scraping device inside the processing cylinder to achieve continuous scraping, cleaning, and uniform dispersion of materials before they enter the granulation zone. The scraping blades, aided by elastic plates, automatically adhere to the cylinder wall, effectively removing adhering materials and preventing material accumulation that could affect granulation quality. This also reduces the frequency of manual cleaning and improves the continuity of equipment operation. The dispersing mesh, driven by a linkage shaft, performs elliptical motion, thoroughly breaking up clumps of material and ensuring a more uniform distribution of material into the granulation disc, thus improving the stability and consistency of granule formation. Furthermore, the water guide components and spray nozzles within the device enable directional rinsing and wetting, keeping the inside of the processing cylinder clean and preventing material from drying out, further improving granulation efficiency and equipment hygiene. The overall structure achieves multi-functional collaboration between scraping, dispersion, wetting, and granulation, significantly enhancing the automation level of the granulation process and improving granulation quality.

A scraping device 8 is provided at the upper end of the processing cylinder 2. A squeezing roller 9 is provided at the lower end of the processing cylinder 2. The bottom of the squeezing roller 9 contacts a granulation disc 10 for granulation. The outer side of the granulation disc 10 is in contact with the lower inner side of the processing cylinder 2. The bottom output shaft of the first motor 4 passes through the processing cylinder 2 and is connected to a drive wheel 4a. The outer side of the drive wheel 4a is connected to the scraping device 8 through a synchronous belt 4b. The scraping device 8 scrapes away excess material attached to the upper inner side of the processing cylinder 2, and can also clean and disperse the material.

[0030] Please see Figures 3-6 The scraping device 8 includes a connecting block 81 that is fixed to the top of the treatment cylinder 2. A rotating part 82 is provided below the connecting block 81. The rotating part 82 is C-shaped. A driven wheel 83 connected to the synchronous belt 4b is provided at the upper end of the rotating part 82. The right side of the rotating part 82 is fixed to an elastic plate 84. The elastic plate 84 has elasticity and can be deformed and bent. A scraping plate 85 is fixed to the right side of the elastic plate 84. The outer side of the scraping plate 85 is attached to the inner wall of the treatment cylinder 2. The two ends of the scraping plate 85 are chamfered and the outer side is arc-shaped. A guide 86 is installed in the middle of the rotating part 82. The guide 86 is cross-shaped. A water guide 87 is fixed at the top of the guide 86. A connecting part 88 is provided at the bottom of the rotating part 82. A dispersing net 89 is connected to the bottom of the connecting part 88. The dispersing net 89 is inclined.

[0031] The guide member 86 has a cross-shaped guide groove at its lower end. Two sets of opposing sliding members 810 are movably embedded inside the guide groove. A connecting plate 811 is hinged to the bottom of the sliding member 810. A linkage shaft 812 is connected to the bottom of the connecting plate 811. The bottom of the linkage shaft 812 passes through the rotating member 82 and connects to the connecting member 88. A fixing post 813 is vertically welded to the middle of the top of the guide member 86. The top of the fixing post 813 passes through the rotating member 82 and the driven wheel 83 in sequence and is fixed inside the connecting block 81.

[0035] When the powder enters the processing cylinder 2, the first motor 4 is started to work. The first motor 4 drives the drive wheel 4a to rotate, which causes the synchronous belt 4b to drive the driven wheel 83 to rotate. The driven wheel 83 drives the rotating component 82 to rotate. During the rotation of the rotating component 82, it achieves circumferential rotation, which causes the elastic sheet 84 to cause the scraping blade 85 to scrape off the excess material attached to the inner wall of the processing cylinder 2. During the rotation of the rotating component 82, the linkage shaft 812 at the lower end moves along with it. During the movement, the linkage shaft 812 drives the connecting plate 811 to move along with it. The two sets of sliding parts 810 at the top end can slide in the guide groove in the guide part 86. During the sliding process, the dispersing net 89 connected at the lower end can perform elliptical circumferential motion, which can disperse the falling material.

[0036] The material falls onto the upper end of the granulation disc 10, and the second motor 7 is started. The second motor 7 drives the granulation disc 10 to rotate, and works with the extrusion roller 9 to granulate the material. Finally, the material is discharged from the granulation hopper 3. If it is necessary to clean the inside of the processing cylinder 2, the external water pipe can be connected to the connecting pipe 5. Water enters the water tank 87a through the connecting pipe 5 and is then sprayed out through the water guide 87, working with the scraper blade 85 for efficient cleaning.
