Description

Technical Field

[0001] This invention relates to the field of ultrafine pulverization technology, and in particular to an ultrafine pulverization device and process for the preparation of aralia elata. Background Technology

[0002] Aralia elata (also known as bilberry or cranberry) is a small fruit that grows in Asia and Europe. It is typically red or bluish-purple and resembles a small berry in shape. Rich in anthocyanins, vitamin C, and minerals, aralia elata possesses antioxidant properties and is often used for nutritional supplementation, promoting blood circulation, and boosting immunity. Furthermore, it has gained attention for its potential benefits to eye health and anti-aging. Therefore, its production is closely monitored. To ensure its nutritional value is not lost, the production process for aralia elata juice involves a pulverizing step to preserve its nutrients.

[0003] The current crushing process mainly relies on the impact of hammers and toothed rings to break down materials. The crushed materials are then driven by airflow, colliding with each other during their spiral ascent, further improving crushing precision. Once the material reaches a level where suction is applied, it is transported through ventilation ducts to the next processing stage. However, this process presents several problems. First, material transport largely depends on conveying devices such as air pumps or augers, and the material inlet position is fixed. This results in most of the material concentrating near the toothed ring close to the inlet. Increasing the feeding speed causes subsequent material to cover the preceding material, leading to material accumulation during crushing and hindering effective lifting, thus affecting the crushing effect. Therefore, to ensure processing efficiency, a slower feeding speed is usually required, which reduces the production efficiency of the crushing process. Summary of the Invention

[0004] The main objective of this invention is to provide an ultrafine pulverizing device for the preparation of aralia elata, which aims to improve the pulverizing production efficiency.

[0005] To achieve the above objectives, the present invention proposes an ultrafine pulverizing device for the preparation of *Aristolochia debilis*, comprising a pulverizer, the pulverizer including: The base and the top cover are detachably and fixedly connected, and the base and the top cover are respectively provided with a first inlet and a second inlet facing one side; A multi-stage crushing module is provided in the base and the top cover. The multi-stage crushing module includes a primary crushing component and a secondary crushing component, which are arranged in order from low to high. The primary crushing component includes a crushing disc, a toothed ring and several hammers. Each hammer is arranged along the circumference of the crushing disc and is used to cooperate with the toothed ring to crush the material. The toothed ring is located on the outside of the crushing disc. A flow guide shroud is installed at the secondary crushing component to guide the material crushed by the primary crushing component. An exhaust pipe is installed on the top of the cover and is used to discharge the crushed material. The exhaust pipe is connected to an external ventilation device. A drive module is disposed between the bottom wall of the base and the grinding disc, and is used to drive and control the rotation of the grinding disc.

[0006] In one possible implementation, the secondary crushing assembly includes a guide plate and a lifting cylinder. The guide plate is located below the second feed inlet. A grinding cylinder is fixedly connected to the axial position of the guide plate. An air guide pipe is rotatably arranged inside the grinding cylinder. The outer wall of the air guide pipe grinds against the grinding cylinder. A lifting cylinder is rotatably connected to the air guide pipe. The lifting cylinder is slidably connected to the air outlet pipe. The lifting cylinder is fixedly connected to the top wall of the upper cover. The telescopic shaft of the lifting cylinder is fixedly connected to the lifting cylinder.

[0007] In one possible implementation, the upper side of the guide plate is inclined downwards towards the axis.

[0008] In one possible implementation, the grinding cylinder has a guide cone surface on the side facing the axis.

[0009] In one possible implementation, the air duct is provided with a discharge trough.

[0010] In one possible implementation, a fan cylinder is fixedly connected to the lower side of the air guide pipe, a telescopic cylinder is coaxially fixedly connected to the lower side of the fan cylinder, a filter fan ring is fixedly connected to the lower end of the telescopic cylinder, and the filter fan ring is coaxially fixedly connected to the grinding disc.

[0011] In one possible implementation, the lower side of the guide plate is an arc-shaped surface.

[0012] This invention significantly improves crushing efficiency and production stability by optimizing material flow and the crushing process. Under the action of the air guide pipe and the guide plate, the material falls more quickly, reducing residence time and improving flowability. After initial crushing, the material is drawn upwards in a spiral motion by the rotating crushing disc through the air outlet pipe. Material that has reached the crushing standard is quickly sucked away, while material that has not reached the standard continues to rotate. During this process, the falling material collides with the high-speed rotating crushing material; the intermittent collision of coarse and fine materials effectively accelerates the crushing of larger particles, further enhancing the impact effect. Through this cyclical collision and crushing, crushing efficiency is improved, the crushing effect is more stable, and the material feeding and discharging speeds are also accelerated, thus significantly improving overall production efficiency.

[0013] Another objective of this invention is to propose an ultrafine grinding process for the preparation of aronia berries, which aims to help protect the nutrients of aronia berries and achieve better processing results.

[0014] To achieve the above objectives, the present invention proposes an ultrafine pulverization process for the preparation of *Aristolochia debilis*, comprising: S1: Preliminary crushing: Dry the aralia berries at low temperature or freeze-dry them, and then put them into a blender or crusher to crush the fruit into coarser particles; S2: Ultrafine grinding: The pre-crushed arugula berries are conveyed to the grinder through a conveying device. Through the multi-stage grinding modules in the grinder, the material can be fed in more evenly and ground at high speed. S3: Discharge: The material generated by multi-stage crushing is stably discharged through the exhaust equipment outside the air duct, so as to be further processed or transferred to subsequent production stages.

[0015] Another technical solution of the present invention achieves uniform crushing and efficient processing of materials through the division of labor in preliminary crushing, ultrafine crushing, and stable output. This optimizes material flowability, reduces material accumulation, and ensures high crushing precision, thereby improving overall production efficiency and helping to protect the nutrients of the aronia berry, resulting in superior processing effects.

[0019] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Example 1 This invention proposes an ultrafine pulverizing device for the preparation of aralia elata; Reference Figures 1 to 4 In this embodiment of the invention, the ultrafine pulverizing equipment for preparing aristolochic acid berries includes a pulverizer. The pulverizer includes a base 11, a top cover 12, a multi-stage pulverizing module, a flow guide shroud 16, an air outlet duct 17, and a drive module. The base 11 and the top cover 12 are detachably fixedly connected. The base 11 and the top cover 12 are respectively provided with a first inlet 131 and a second inlet 132 facing one side, which is convenient for connecting external pipes to the two inlets. After the external pipes are installed, the overall appearance of the equipment is improved. The multi-stage pulverizing module is set in the base 11 and the top cover 12. The multi-stage pulverizing module includes a first-stage pulverizing component 14 and a second-stage pulverizing component 15. The primary crushing component 14 and the secondary crushing component 15 are arranged sequentially from low to high. The primary crushing component 14 includes a crushing disc 141, a toothed ring 142, and several hammers 143. Each hammer 143 is arranged along the circumference of the crushing disc 141 and is used to cooperate with the toothed ring 142 to crush the material. The toothed ring 142 is located on the outside of the crushing disc 141. The guide shroud 16 is located at the position of the secondary crushing component 15 and is used to guide the material crushed by the primary crushing component 14. The air outlet duct 17 is located on the top of the upper cover 12 and is used to discharge the crushed material. The air outlet duct 17 is connected to an external exhaust device. The drive module is located between the bottom wall of the base 11 and the crushing disc 141 and is used to drive and control the rotation of the crushing disc 141.

[0022] By adding a secondary crushing component 15 to the primary crushing component 14, the material feeding efficiency within the crusher can be improved, reducing the workload of the primary crushing component 14. This design allows materials to enter the primary and secondary crushing components in batches. After multiple crushing operations by the secondary crushing component, the crushing effect is significantly improved. Furthermore, the material crushed by the secondary crushing component falls more evenly into the primary crushing component 14, thereby optimizing the uniformity of crushing and reducing the equipment load, ensuring the efficient and stable operation of the crusher.

[0023] By optimizing the material flow and crushing process, crushing efficiency and production stability are significantly improved. Under the action of the air guide pipe 23 and the guide plate 21, the material falls more quickly, reducing residence time and improving flowability. After initial crushing, the material is drawn upwards in a spiral motion by the exhaust pipe 17 and the rotating crushing disc 141. Material that has reached the crushing standard is quickly sucked away, while material that has not reached the standard continues to rotate. During this process, the falling material collides with the high-speed rotating crushing material; the intermittent collision of coarse and fine materials effectively accelerates the crushing of larger particles, further enhancing the impact effect. Through this cyclical collision and crushing, crushing efficiency is improved, the crushing effect is more stable, and the material feeding and discharging speeds are also accelerated, thus significantly improving overall production efficiency.

[0024] refer to Figures 2 to 4 The secondary crushing component 15 includes a guide plate 21 and a lifting cylinder 25. The guide plate 21 is located below the second feed inlet 132. The grinding cylinder 22 is fixedly connected to the axial position of the guide plate 21. The air guide pipe 23 is rotatably disposed inside the grinding cylinder 22. The outer wall of the air guide pipe 23 grinds against the grinding cylinder 22. The lifting cylinder 24 is rotatably connected to the air guide pipe 23. The lifting cylinder 24 is slidably connected to the air outlet pipe 17. The lifting cylinder 25 is fixedly connected to the top wall of the upper cover 12. The telescopic shaft of the lifting cylinder 25 is fixedly connected to the lifting cylinder 24.

[0025] The secondary crushing component is designed so that the lifting cylinder 24 moves via the lifting cylinder 25, allowing the material falling onto the guide plate 21 to smoothly fall through the gap between the grinding cylinder 22 and the air guide pipe 23. The grinding cylinder 22 and the air guide pipe 23 maintain a relative rotational relationship. A motor installed on the top wall of the upper cover 12, through the cooperation of the motor and gears, drives the air guide pipe 23 to rotate. In this way, the material falling between the grinding cylinder 22 and the air guide pipe 23 will be rapidly crushed during rotation. The interaction force between the grinding cylinder 22 and the air guide pipe 23 effectively crushes the material, especially for agglomerated materials, achieving rapid breakage, thereby reducing the working pressure at the primary crushing component 14 and improving the overall crushing efficiency.

[0026] Furthermore, by fixing the guide plate 21 to a position relatively fixed below the second feed inlet 132 and allowing the two to rotate, the material flow can be further optimized. During the crushing process, the guide plate 21 is rotated by the material. Utilizing this rotational force, driven by friction from the material's compression, the two rotate at different speeds. The rotation of the guide plate 21 allows the material falling onto it to slide more evenly, ensuring a more uniform distribution of material into the gap between the grinding cylinder 22 and the air guide pipe 23. This results in a more uniform material distribution, ensuring the uniformity of the secondary crushing process and improving crushing effect and efficiency. Overall, this design not only improves the uniformity of crushing but also reduces the equipment's workload, ensuring the stable and efficient operation of the crusher.

[0027] To ensure the relative rotational relationship between the grinding cylinder 22 and the air guide pipe 23, a damper can be installed at the connection between the guide plate 21 and the upper cover 12. The damper controls the rotational speed of the guide plate 21 and prevents it from rotating excessively, thereby maintaining a precise rotational relationship between the grinding cylinder 22 and the air guide pipe 23. This not only helps to maintain uniform material feeding but also ensures a uniform pulverization effect when the material enters between the grinding cylinder 22 and the air guide pipe 23.

[0028] The damper effectively reduces fluctuations in the crushing effect caused by uneven material flow or unstable rotation, thereby improving the crusher's efficiency. It ensures a stable flow rate of material entering the crushing zone, preventing accumulation or stagnation caused by excessively fast or slow flow, thus guaranteeing a smooth crushing process. This optimizes the crushing effect and improves the stability and production efficiency of the entire crushing system.

[0029] refer to Figures 2 to 4 The upper side of the guide plate 21 is inclined downward towards the axis.

[0030] By optimizing the side profile of the guide plate 21, an inclination angle of 10° to 30° is set. This inclination range ensures good material flow while preventing material slippage or jamming. The inclination angle between 10° and 30° balances the material flow speed, avoiding impact problems caused by excessively fast flow and material stagnation caused by excessively slow flow. This allows the material fed through the second inlet 132 to naturally gather at its center under the guidance of the guide plate 21, promoting uniform material distribution and providing more efficient material input for subsequent crushing processes, further improving the crushing effect. This flow optimization not only improves the working efficiency of the crusher but also ensures the stability of the crushing process.

[0031] refer to Figures 2 to 4 The guide cone surface 221 is located on the side of the grinding cylinder 22 facing the axis.

[0032] By setting the guide cone surface 221, the material, after being guided by the guide plate 21, can smoothly fall into the guide cone surface 221. This effectively guides the flow of the material, allowing it to enter the crushing process more quickly. The guiding effect of the guide cone surface reduces the material's residence time and unnecessary flow resistance, ensuring that the material can be quickly and evenly fed into the gap between the grinding cylinder 22 and the air guide pipe 23, and finally evenly sprinkled from the guide plate 21, thereby significantly improving the overall crushing efficiency. This optimization not only speeds up the material processing speed but also improves the working efficiency of the crusher, reduces energy consumption, and makes the entire crushing process more efficient and stable.

[0033] refer to Figures 2 to 4 The lower side of the guide plate 21 is an arc surface 211.

[0034] The design of the curved surface 211 allows for a more stable airflow at this location. This helps maintain greater stability in the airflow agitated by the fan shroud 26, effectively guiding the pulverized material. Thus, the material processed by the multi-stage pulverizing module can better collide under the guidance of the airflow, effectively improving pulverizing efficiency and fineness, further enhancing the overall pulverizing effect. This adjustment in airflow guidance optimizes the material flow path, avoids airflow instability or turbulence, and improves the precision and uniformity of the entire pulverizing process.

[0035] Example 2 This embodiment improves the external features of the air duct 23 based on embodiment 1; refer to Figures 3 to 4 The unloading chute 231 is located on the air guide pipe 23.

[0036] By setting up the discharge chute 231, the gap between the outer wall of the air guide pipe 23 and the grinding cylinder 22 is increased, allowing the material placed between them to fall more quickly as the air guide pipe 23 moves upward, especially materials that have already undergone different degrees of crushing. This allows the material to fall quickly from the guide plate 21, reducing the material's residence time and improving overall flowability. The material that has undergone preliminary crushing, under the suction of the air outlet pipe 17, exhibits a spiral upward movement as the crushing disc 141 rotates. Some of the material that has reached the crushing standard is sucked away by the air outlet pipe 17, while the material that has not reached the standard continues to rotate inside the crusher. During this process, the falling material collides with the high-speed rotating crushed material. Through the intermittent collision of coarse and fine materials, larger particles can be rapidly broken, further enhancing the impact between materials. This cyclical process of collision and crushing effectively improves crushing efficiency, ensures the stability of the crushing effect, and also increases the feeding and discharging speeds, thereby significantly improving production efficiency.

[0037] Example 3 This embodiment improves the rotation drive of the air guide tube 23 based on embodiment 1; refer to Figures 2 to 4 The fan cylinder 26 is fixedly connected to the lower side of the air guide pipe 23. The lower side of the fan cylinder 26 is coaxially fixedly connected to the telescopic cylinder 27. The lower end of the telescopic cylinder 27 is fixedly connected to the filter fan ring 28. The filter fan ring 28 is coaxially fixedly connected to the pulverizing disc 141.

[0038] The pulverizing disc 141 transmits driving force to the fan cylinder 26, eliminating the need for a separate external drive mechanism and thus saving production costs. Furthermore, the telescopic cylinder 27 ensures that the relative position between the filter fan ring 28 and the pulverizing disc 141 remains unchanged as the fan cylinder 26 moves along the axis with the air guide pipe 23. This ensures that the force generated by the rotation of the pulverizing disc 141 is stably transmitted to the filter fan ring 28, thereby maintaining a stable pulverizing effect between the air guide pipe 23 and the inner wall of the grinding cylinder 22. Therefore, the overall pulverizing effect of the secondary pulverizing assembly 15 remains consistent, improving not only the operational stability of the equipment but also further optimizing the energy efficiency and effectiveness of the pulverizing process.

[0039] Example 4 This invention also proposes an ultrafine pulverization process for the preparation of *Aristolochia debilis*, referring to... Figures 1 to 4 include: S1: Preliminary crushing: Dry the aralia berries at low temperature or freeze-dry them, and then put them into a blender or crusher to crush the fruit into coarser particles; Using low-temperature or freeze-drying methods can effectively preserve the nutritional components of aronia berries and avoid the destruction of nutrients (such as vitamin C and anthocyanins) by high temperatures. Crushing the aronia berries into coarse particles using a blender or crusher provides a good material foundation for subsequent ultrafine grinding, which helps improve grinding efficiency.

[0040] S2: Ultrafine grinding: The pre-crushed arugula berries are conveyed to the grinder through a conveying device. Through the multi-stage grinding modules in the grinder, the material can be fed in more evenly and ground at high speed. The multi-stage crushing module in the crusher ensures more uniform material feeding and achieves a finer crushing effect through high-speed crushing. This means that the material is more uniform and finer at this stage, avoiding uneven particle size and improving crushing precision and efficiency. The combination of uniform material feeding and high-speed crushing helps improve crushing stability, reduces the risk of material accumulation or uneven distribution, and ensures the high efficiency of the entire process.

[0041] S3: Discharge: The material generated by multi-stage crushing is stably discharged through the exhaust device outside the air outlet duct 17, so as to be further processed or transferred to subsequent production stages.

[0042] The stable discharge system, utilizing exhaust ducts and external ventilation equipment, ensures that the pulverized material flows smoothly into subsequent production stages. This design prevents material blockage or obstruction during discharge, maintaining the continuity and efficiency of the production line. A stable discharge system effectively prevents poor pulverization caused by material accumulation during feeding, thereby improving the stability and efficiency of the entire production process.

[0043] This crushing process, through the division of labor between preliminary crushing, ultrafine crushing, and stable output, enables uniform crushing and efficient processing of materials. It optimizes material flowability, reduces material accumulation, and ensures high crushing precision, thereby improving overall production efficiency and helping to preserve the nutrients of the aronia berry, achieving superior processing results.
