Technical Field

[0001] This invention relates to the field of pharmaceutical granule preparation technology, and in particular to a device and method for preparing granules of *Ficus hirta* (a type of medicinal herb). Background Technology

[0017] A preparation method based on a device for preparing granules of *Ficus hirta* (a type of medicinal herb) includes the following steps:

[0018] S1. Place the root of the five-finger peach into the slicing mechanism for slicing;

[0019] S2. Five-finger peach slices are placed into the heat-insulating shell and boiled to extract the effective components;

[0020] S3. Discharge the decoction into the outer shell and filter it for separation;

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The filtration mechanism of this invention works in conjunction with the rinsing component. When the device is in the preparation process, the decoction and impurities enter the outer shell at the same time. The impurities are filtered out by the filter plate and remain between the two movable plates for easy cleaning. When cleaning the pipes, the water cannot flow inside the outer shell and flows to the other side of the filter plate through the connecting pipe. This not only cleans the pipes but also backwashes the filter plate, removing adsorbed impurities from its surface. This increases the lifespan of the device and prevents blockages.

[0025] 2. The slicing mechanism of this invention can slice the cleaned *Ficus hirta*, ensuring that the decoction after decocting has good medicinal efficacy, improving the granule production effect of the device, and reducing the decoction time of the device, thus improving the preparation efficiency. Through two clamping rollers and clamping plates, the root of *Ficus hirta* can be well clamped, preventing it from moving freely during slicing, resulting in slices with more uniform thickness and shape, which can be better processed during decoction.

Detailed Implementation

[0038] 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.

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, a device for preparing granules of five-finger peach includes a base frame 1, which supports the entire device and makes it more stable during use. A decoction mechanism 2 for decocting sliced ​​five-finger peach is fixedly installed on the upper end of the base frame 1. The decoction mechanism 2 has the functions of heating and sealing. When five-finger peach is placed in the decoction mechanism 2, it can be decocted by mixing with water and heating to produce a decoction with the medicinal effects of five-finger peach. During the decoction, it can also be stirred to improve the decoction effect of the device and make the prepared five-finger peach granules have high purity.

[0041] Then, a slicing mechanism 3 for slicing five-finger peach is fixedly installed at the upper end of the decoction mechanism 2. The main part of five-finger peach is its root, and the bark of the root is relatively thick. If it is directly put into water for decoction, it will not only take a long time, but the medicinal effect of the decoction will also be low. By slicing, the contact area between five-finger peach and water is increased, which reduces the decoction time and ensures the medicinal effect. A discharge component 4 for discharging five-finger peach decoction is fixedly installed at the lower end of the decoction mechanism 2. The discharge speed of the decoction can be controlled according to different situations. After the decoction is finished, when the discharge speed is low, the five-finger peach slices in the decoction mechanism 2 will not be discharged with the decoction, which can facilitate the subsequent filtration process.

[0042] A flushing assembly 5 for flushing devices is provided in front of the discharge assembly 4. A filter mechanism 6 for filtering impurities is provided below the flushing assembly 5. The decoction of Five-Finger Peach needs to be filtered by the filter mechanism 6 to better carry out subsequent work. The flushing assembly 5 can clean the pipe for discharging the decoction. During the cleaning process, the filter components in the filter mechanism 6 can be back-flushed to ensure that the surface of the filter components does not adsorb impurities. A compression drying device 7 is provided in front of the filter mechanism 6. The filtered decoction will enter the compression drying device 7 and then be concentrated to further improve the efficacy of the decoction. Then the decoction is dried and ground. A granulation device 8 for granulation is provided in front of the compression drying device 7. After the powdered decoction enters the granulation device 8, other excipients are added for granulation.

[0043] To further explain, in order to better decoct Five-Finger Peach, such as... Figure 3 and Figure 4 As shown, the decoction mechanism 2 includes an insulated shell 21, which has a good heat preservation effect, ensuring the decoction effect of the device and reducing some heat waste. A heating tank 22 is fixedly installed inside the insulated shell 21. Five-finger peach slices and water are added to the heating tank 22 for heating and decoction. Three water inlet valves 23 are fixedly installed at the upper end of the insulated shell 21. The lower ends of the three water inlet valves 23 all penetrate into the inner cavity of the heating tank 22 and are fixedly installed with spray heads 24. Water can be added into the heating tank 22 through the water inlet valves 23 and the spray heads 24. The water will enter the heating tank 22 by spraying, which facilitates subsequent cleaning. The inner cavity of the heating tank 22 is provided with stirring blades 25 for stirring the decoction liquid. Stirring during heating can increase the decoction effect of the heating tank 22.

[0044] To further explain, in order to process the complete root of the five-finger peach into slices, such as... Figure 5 As shown, the slicing mechanism 3 includes a slicing box 31. A motor 32 is fixedly installed at the front end of the slicing box 31. A discharge hole 33 is opened on the lower inner wall of the slicing box 31. A cutting blade 34 is rotatably installed in the inner cavity of the discharge hole 33. The cutting blade 34 is connected to a stirring blade 25. The stirring blade 25 can drive the cutting blade 34 to rotate, so that the cutting blade 34 can slice the root of the five-finger peach. Three clamping plates 35 are arranged in an array in the inner cavity of the discharge hole 33. The three clamping plates 35 will clamp the root of the five-finger peach to ensure that it can remain stable and not shift when it is cut by the cutting blade 34, so that the slice thickness and shape are relatively uniform.

[0045] Then, two meshing gears 36 are provided on the inner wall of the front side of the slicing box 31. The two gears 36 can rotate at the same time and in opposite directions. The gear 36 on the left side is connected to the output end of the motor 32 by a belt. The output end of the motor 32 can drive the gear 36 on the left side to rotate. Under the meshing action, the gear 36 on the right side rotates in the opposite direction to the output end of the motor 32. Two clamping rollers 37 are rotatably installed in the inner cavity of the slicing box 31. When feeding, the five-finger peach should be placed between the two clamping rollers 37.

[0046] Then, the clamping roller 37 on the left is connected to the output end of the motor 32, and the clamping roller 37 on the right is connected to the gear 36 on the right. The clamping roller 37 on the left is driven to rotate by the output end of the motor 32, and the clamping roller 37 on the right is driven to rotate by the gear 36 on the right. When the motor 32 is started, the two clamping rollers 37 will rotate in a direction that brings them closer to each other. Several teeth 38 are fixedly installed in an array on the arc-shaped inner wall of the two clamping rollers 37. The teeth 38 will pierce the surface of the root of the five-finger peach and move it downward at a uniform speed in conjunction with the two clamping rollers 37. During feeding, one peach after another is required.

[0047] To further explain, in order to control the discharge rate of the decoction inside the heat-insulating shell 21, such as... Figure 7 As shown, the discharge assembly 4 includes a top plate 41, an L-shaped tube 42 fixedly installed at the lower end of the top plate 41, a bottom plate 43 fixedly installed inside the L-shaped tube 42, the bottom plate 43 serving as a support, a cylinder 44 fixedly installed on the upper horizontal end face of the bottom plate 43, a conical block 45 fixedly installed at the output end of the cylinder 44, the conical block 45 being located inside the top plate 41, when the cylinder 44 is activated, it pulls the conical block 45 downward, the decoction in the heating tank 22 will enter the L-shaped tube 42, enabling the device to discharge the decoction in the heating tank 22, a protective shell 46 fixedly installed at the lower end of the conical block 45, a friction strip 47 fixedly installed on the front side of the arc-shaped surface of the friction strip 47, the protective shell 46 and the friction strip 47 can both move downward with the conical block 45.

[0048] To further explain, in order to clean the L-shaped tube 42 after the device is used, such as... Figure 8 As shown, the flushing assembly 5 includes a Z-shaped tube 51, which is connected to three water inlet valves 23. When the water inlet valves 23 release water into the heating tank 22, the water also flows into the Z-shaped tube 51. A sleeve 52 is fixedly installed in the inner cavity of the rear side of the Z-shaped tube 51. A cross block 53 is fixedly installed in the inner cavity of the Z-shaped tube 51 on the rear side of the sleeve 52. A reciprocating screw 54 is rotatably installed at the front end of the cross block 53. A water-blocking sleeve 55 is threadedly connected to the arc-shaped surface of the reciprocating screw 54. The connection between the water-blocking sleeve 55 and the sleeve 52 is a sliding connection. Under the action of the threaded connection, when the reciprocating screw 54 rotates, it can drive the water-blocking sleeve 55 to move left and right.

[0049] Then, the arc-shaped surface of the water-blocking sleeve 55 is arrayed with four rectangular grooves. When the cleaning device is not in use, the rectangular grooves on the surface of the water-blocking sleeve 55 will be located in the inner cavity of the sleeve 52. The rear end of the reciprocating screw 54 is fixedly installed with a friction wheel 56. The arc-shaped surface of the friction wheel 56 can contact the friction strip 47. Only when the friction strip 47 moves down a certain distance will the friction strip 47 contact the surface of the friction wheel 56. When it is necessary to discharge the decoction in the heating tank 22, the friction strip 47 will not contact the surface of the friction wheel 56 as the conical block 45 moves down a certain distance. The front end of the reciprocating screw 54 extends through the Z-shaped tube 51 and is fixedly installed with a pulley 57. The pulley 57 rotates with the reciprocating screw 54.

[0050] The specific implementation method of this embodiment is as follows: the cleaned root of the five-finger peach is placed in the slicing box 31, and then the motor 32 is started so that it drives the two clamping rollers 37 to move towards each other through the gear 36. The teeth 38 will clamp the root of the five-finger peach and move it slowly downward. The clamping plate 35 will also clamp the root of the five-finger peach so that the root of the five-finger peach cannot move freely when slicing. When the two clamping rollers 37 move the root of the five-finger peach downward, the rotating cutting blade 34 can slice it.

[0051] The slices of *Ficus hirta* will fall into the heating tank 22. Appropriate water is added to the heating tank 22 through the three water inlet valves 23, and heating and decoction can be carried out. The stirring blade 25 will also stir it to reduce the decoction time and ensure the efficacy of the decoction. After the decoction is completed, the cylinder 44 is activated to pull the conical block 45 downward. The decoction in the heating tank 22 will flow downward into the L-shaped tube 42. The protective shell 46 and friction strip 47 will move downward with the conical block 45. After the decoction and *Ficus hirta* slices in the heating tank 22 are discharged, the conical block 45 and friction strip 47 need to continue to move downward.

[0052] The friction strip 47 contacts the friction wheel 56 and drives it to rotate. The friction wheel 56 drives the reciprocating screw 54 and the pulley 57 to rotate simultaneously. Under the action of the threaded connection, the reciprocating screw 54 can drive the water-blocking sleeve 55 to move to the left when it rotates. After the water-blocking sleeve 55 moves a certain distance, the water in the Z-shaped pipe 51 will enter the L-shaped pipe 42 through the rectangular groove on the surface of the water-blocking sleeve 55.

[0053] Example 2

[0054] This embodiment is a further improvement on the filter mechanism 6 based on the first embodiment, enabling the device to achieve backwashing after filtration, thus effectively cleaning the inside of the pipeline.

[0055] To further explain, in order to filter the decoction liquid inside the heat-insulating shell 21, such as... Figure 9 As shown, the filter mechanism 6 includes a housing 61. Two water inlet holes 62 are opened on the upper side of the inner wall of the housing 61, and a material discharge groove 63 is opened on the lower side of the inner wall of the housing 61. A filter assembly 64 is provided in the inner cavity of the housing 61. A belt sleeve 65 is slidably installed on the arc-shaped surface of the housing 61. The belt sleeve 65 is connected to the pulley 57 by a belt. The pulley 57 can drive the belt sleeve 65 to rotate. A connecting pipe 66 is fixedly installed on the arc-shaped surface of the belt sleeve 65. A slot 67 is opened on the other side of the arc-shaped surface of the belt sleeve 65. The slot 67 is the same size and shape as the material discharge groove 63. When the device is in use, the connecting pipe 66 is located on the lower side of the housing 61. When the device needs to be cleaned, the belt sleeve 65 can be rotated to move the connecting pipe 66 to the upper side of the housing 61.

[0056] Specifically, the connecting pipe 66 connects the two water inlets 62, and the slot 67 and the discharge trough 63 overlap. Solid impurities piled inside the outer shell 61 will move downward from the discharge trough 63 and the slot 67. At the same time, the water used for cleaning inside the outer shell 61 will flow through the two water inlets 62 in the connecting pipe 66.

[0057] To further explain, in order to facilitate the subsequent rinsing work, as shown in the figure, the filter assembly 64 includes two fixed plates 641 fixedly installed on the inner wall of the outer shell 61. Each of the two fixed plates 641 has a movable plate 642 on its rear side. A connecting rod 643 is fixedly installed between the two movable plates 642. A filter plate 644 is installed between the two fixed plates 641. The filter plate 644 filters the decoction in the heating tank 22. An inclined block 645 is fixedly installed at the rear end of the movable plate 642 on the rear side. This is to allow the decoction and the sliced ​​five-finger peach to enter between the two movable plates 642, so as to facilitate the subsequent cleaning of the five-finger peach slices.

[0058] Then, a second friction wheel 646 is rotatably installed on the front end of the fixed plate 641 located at the rear. The second friction wheel 646 is tightly fitted with the inner wall of the belt sleeve 65. The second friction wheel 646 is connected to the connecting rod 643 by a belt. When the belt sleeve 65 rotates, the second friction wheel 646 will drive the connecting rod 643 and the two movable plates 642 to rotate under the action of friction, so that the cleaning water cannot directly enter between the two movable plates 642, but needs to enter through the connecting pipe 66 to achieve the purpose of backwashing.

[0059] The specific implementation of this embodiment is as follows: When the device is in normal use, the decoction and the sliced ​​five-finger peach will flow between the two movable plates 642 and then be filtered by the filter plate 644. The decoction will flow directly into the compression drying device 7, while the five-finger peach slices and impurities will be blocked by the filter plate 644 and remain between the two movable plates 642. The pulley 57 can drive the belt sleeve 65 and the connecting pipe 66 to rotate. The friction wheel 646 will also rotate under the action of friction, driving the connecting rod 643 and the two movable plates 642 to rotate. This prevents the water in the L-shaped pipe 42 from flowing inside the outer shell 61 and can only flow through the connecting pipe 66 to the other side of the filter plate 644 to perform reverse rinsing of the filter plate 644. This can better clean the outer shell 61 and also increase the service life of the filter plate 644.

[0060] The slot 67 rotates with the belt sleeve 65. When the slot 67 overlaps with the feeding trough 63, the outer shell 61 can no longer maintain a sealed state. The five-finger peach slices and impurities between the two movable plates 642 will fall out of the device with the washing water, thus cleaning the device.

[0061] It should be noted that the specific installation method, circuit connection method and control method of the motor 32 and cylinder 44 in this invention are all conventional designs, and will not be described in detail in this invention.

[0064] S1. Place the cleaned root of the five-finger peach into the slicing mechanism 3 and slice it using the cutting blade 34.

[0065] S2. Slices of five-finger peach are placed into the heat preservation shell 21, and an appropriate amount of water is added for decoction to extract the effective components;

[0066] S3. Discharge the decoction into the outer shell 61, filter and separate it to remove solid residue and obtain pure medicinal liquid;

[0067] S4. Then, the filtered medicinal liquid is concentrated and dried by the compression drying device 7 to increase the concentration of the active ingredients. The dried medicinal liquid is made into a dry extract.

[0068] S5. After mixing the dry extract with an appropriate amount of excipients, granulate it through the granulation device 8 to produce granules for packaging.
