Description

Technical Field

[0001] This invention relates to the field of black fungus powder processing technology, specifically to a pulverizing device and processing technology for ultra-fine low-temperature black fungus powder processing. Background Technology

[0002] Ultrafine pulverization technology is a key processing method for preparing high-quality black fungus powder. It can break dried black fungus into particles of micron or even nanometer size, greatly improving the product's solubility, bioavailability, and taste. Currently, the mainstream equipment for preparing ultrafine black fungus powder in the industry is the high-speed mechanical impact ultrafine pulverizer. The basic working principle of this type of equipment is as follows: the pre-dried block or sheet-shaped black fungus raw material is quantitatively and continuously fed into the top of the pulverizing chamber by a screw conveyor; the material falls freely from the fixed feed port at the top of the chamber and falls directly into the pulverizing area formed by the high-speed rotating pulverizing disc and the stationary pulverizing chamber; the cooling device removes the heat generated during the pulverization process, aiming to achieve "low-temperature" pulverization and protect the heat-sensitive nutrients, natural color, and flavor of the black fungus from high-temperature damage; In practical applications, since the material always falls from a fixed position at the top of the crushing chamber, its initial landing point and trajectory are relatively fixed. This results in most of the material continuously and intensively impacting and accumulating in a limited area on the crushing disc directly below the feed inlet. This causes the input of crushing energy (impact force, friction force) to be highly concentrated in the local arc area of ​​the crushing chamber, resulting in significant uneven load distribution. This concentrated work directly causes the temperature in this local area to rise sharply, forming "hot spots" that are difficult to completely eliminate through conventional cooling. For materials like black fungus, which are rich in heat-sensitive components such as polysaccharides and proteins, local overheating can easily cause Maillard reactions or charring in the powder in this area, resulting in loss of active ingredients, browning, and flavor deterioration, seriously threatening the sensory quality and nutritional efficacy of the ultrafine powder. Therefore, we propose a crushing device and its processing technology for ultrafine low-temperature black fungus powder processing. Summary of the Invention

[0003] The purpose of this invention is to provide a pulverizing device and its processing technology for ultra-fine low-temperature black fungus powder processing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pulverizing device for processing ultra-fine low-temperature black fungus powder, comprising a pulverizing body, a pulverizing tank, a pulverizing disc frame, a main shaft, and a toothed disc. The pulverizing tank is fixedly installed on the top of the pulverizing body.

An installation plate frame is fixedly installed on the drive shaft. The inclined plate frames, collection frame one, and collection frame two are all connected to the installation plate frame through a connecting shaft. Among them, collection frame one and collection frame two are rotatably connected to the connecting shaft.

[0005] Preferably, both collecting frame one and collecting frame two are connected to the connecting shaft with torsion springs. A force-bearing rod is fixedly installed at the end of collecting frame one, and an L-shaped rod is fixedly installed on the inner wall of the diverting ring. The L-shaped rod is located on the movement trajectory of the force-bearing rod. A movable shaft is also provided inside the end of collecting frame two. One end of the movable shaft is slidably connected to the inner wall of the connecting shaft, and a spring mechanism is connected between the movable shaft and the inner wall of the connecting shaft.

[0007] Preferably, an annular disc frame is provided below the mounting disc frame, and the annular disc frame is fixedly installed on the transmission shaft body. A positioning disc frame is provided below the annular disc frame. The positioning disc frame is fixedly connected to the diverter ring through a connecting rod frame. The positioning disc frame is also equipped with a transmission disc frame that is rotatably connected to its inner wall. The inner wall of the transmission disc frame does not contact the outer wall of the transmission shaft body.

[0008] Preferably, an electromagnetic mechanism is fixedly installed on the top of the transmission disc frame, and multiple guide shafts are installed inside the transmission disc frame and slidably connected to its inner wall. One end of the guide shaft is located above the electromagnetic mechanism, and the other end is located above the crushing disc frame. Iron sleeves are fixedly installed at both ends of the guide shaft. When the electromagnetic mechanism is energized, it generates an attractive force on the iron sleeves located above it.

[0009] Preferably, both the crushing disc and the annular disc are provided with multiple through holes. When the electromagnetic mechanism is not energized, the iron sleeve at one end of the guide shaft extends into the through hole on the annular disc, while the iron sleeve at the other end is located above the crushing disc. When the electromagnetic mechanism is energized, the iron sleeve at one end of the guide shaft leaves the through hole on the annular disc, while the iron sleeve at the other end extends into the through hole on the crushing disc.

[0010] Preferably, a return spring is connected between the transmission disc frame and the inner wall of the guide shaft, and a connecting disc frame is provided below the transmission disc frame. The connecting disc frame is fixedly connected to multiple guide shafts. Multiple arc-shaped rod frames are fixedly installed on the connecting disc frame, and a cleaning rod frame is fixedly installed at the end of the arc-shaped rod frame. When the electromagnetic mechanism is not energized, the cleaning rod frame is located above the crushing chamber. When the electromagnetic mechanism is energized, the cleaning rod frame extends into the crushing chamber.

[0011] Preferably, the cleaning rod frame is set in an arc-shaped inclined position.

[0012] Preferably, the power unit includes two rotating shafts installed inside the crushing body, and the rotating shafts are rotatably connected to the inner wall of the crushing body. The rotating shafts are connected by a belt drive mechanism. One of the rotating shafts is fixedly installed with a first driving gear and a second driving gear. A servo motor is also fixedly installed on the crushing body, and the output end of the servo motor is fixedly connected to the other rotating shaft. A driven gear is fixedly installed on the main shaft and meshes with the first driving gear, and a driven gear is installed on the transmission shaft and meshes with the second driving gear.

[0013] The processing technology of a pulverizing device for processing ultrafine low-temperature black fungus powder specifically includes the following steps: S1. The dried black fungus in block or flake form is continuously and evenly fed into the crushing tank through the feeding pipe. S2. Start the power unit to drive the crushing disc frame to rotate at high speed, while simultaneously driving the classifying impeller and mounting disc frame to rotate at low speed. Part of the falling material falls directly into the central area near the crushing disc frame 3, while the rest is intercepted by the rotating inclined plate frame, collection frame one, and collection frame two. The inclined plate frame guides the material it receives to the central peripheral area of ​​the crushing disc frame. As the mounting disc frame rotates, collection frame one and collection frame two are triggered to flip when they reach the preset L-shaped rod or arc-shaped protrusion position on the diversion ring, thus throwing the material they carry to the edge area of ​​the crushing disc frame. S3. The material dispersed at different radial and circumferential positions on the crushing disc frame enters the crushing chamber under high-speed centrifugal action. It is fully impacted, sheared and rubbed between the crushing disc frame and the toothed disc to achieve ultra-fine crushing. The crushed powder rises under the drive of airflow and is classified by particle size by the classifying impeller. The qualified fine powder is collected as the product, and the unqualified coarse powder is thrown back into the crushing chamber by the classifying impeller to continue crushing. S4. After the continuous crushing operation reaches the preset time, or when a decrease in crushing efficiency is detected, the electromagnetic mechanism is energized to generate magnetic force and attract the iron sleeve at the upper end of the guide shaft. This causes the guide shaft to slide downwards against the resistance of the return spring, causing the upper iron sleeve to disengage from the through hole of the annular disc frame. At the same time, the lower iron sleeve is inserted downwards into the corresponding through hole of the crushing disc frame. The cleaning rod frame is then driven by the crushing disc frame and rotates into the crushing chamber at the same high speed as the crushing disc frame. Its arc-shaped inclined blade powerfully scrapes the inner wall of the crushing chamber and the surface of the toothed disc, completely peeling off and breaking up the attached or accumulated fine powder and flakes, which are then carried out by the continuous airflow and material flow. S5. After the cleaning operation has continued for a preset time, the electromagnetic mechanism is de-energized, the magnetic force disappears, and the guide shaft is reset under the action of the reset spring. The upper iron sleeve is reinserted into the through hole of the annular disc frame, and the lower iron sleeve is pulled out from the through hole of the crushing disc frame. The cleaning rod frame then rises and exits the crushing chamber, returning to the auxiliary flow guiding state.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the inclined plate frame, collection frame one and collection frame two set below the classifying impeller and driven to rotate by the mounting plate frame, together with the L-shaped rod frame and arc-shaped protrusion fixed to the inner wall of the diversion ring, can actively intercept the falling material and throw it in fixed points and batches onto the crushing plate frame in an area far away from the feed inlet, thereby making the crushing load and the generated heat evenly distributed, effectively eliminating local hot spots that cause the loss of heat-sensitive components, and providing a guarantee for achieving true low-temperature ultrafine crushing; 2. In this invention, the first collection frame achieves flipping by direct collision between the force-bearing rod at its end and the L-shaped rod; the second collection frame converts axial sliding into rotational motion by the cooperation of the movable shaft, arc groove, rolling ball and arc protrusion at its end. Furthermore, due to the staggered arrangement of the L-shaped rod and arc protrusion on the diversion ring, the material can be alternately and evenly conveyed to different positions on the circumference of the crushing chamber, thus achieving dynamic optimization of the material spatial distribution. 3. This invention achieves the switching of the working mode of the cleaning rod frame through the electromagnetic mechanism, guide shaft, iron sleeve and the cooperation with the through holes on the crushing disc frame and the annular disc frame, which are set on the transmission disc frame. When cleaning is required, the electromagnetic mechanism is energized, driving the guide shaft to move and switching the connection object of the iron sleeve, so that the cleaning rod frame is driven by the high-speed rotating crushing disc frame, and rotates into the crushing chamber at high speed for powerful scraping and cleaning, thereby efficiently removing the accumulated material and flaking on the inner wall and effectively preventing the material from pasting.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-13 This invention provides a technical solution: a pulverizing device for processing ultra-fine low-temperature black fungus powder. This invention addresses the technical problems in the background art by making corresponding improvements. It includes a pulverizing body 1, a pulverizing tank 2 fixedly installed on the top of the pulverizing body 1, a feeding pipe 21 provided on the top of the pulverizing tank 2 for continuously feeding dried black fungus material, a diverting ring 22 fixedly installed inside the pulverizing tank 2, the diverting ring 22 being ring-shaped, a pulverizing disc frame 3 rotatably connected to the bottom inner wall of the pulverizing tank 2, and a main shaft 31 fixedly installed on the pulverizing disc frame 3. The main shaft 31 is rotatably connected to the inner wall of the pulverizing tank 2 via a bearing (not shown in the figure). The wall is also fixedly installed with a toothed disc 4, which forms an annular crushing chamber 5 between the toothed disc 4 and the crushing disc frame 3. When the crushing disc frame 3 rotates at high speed, the material is crushed into ultrafine powder by strong impact, shearing and friction between the crushing disc frame 3 and the toothed disc 4. A classifying impeller 6 is installed on the top of the crushing tank 2, and a drive shaft 61 is fixedly installed on the bottom of the classifying impeller 6. A power unit 7 is provided in the crushing body 1 to drive the drive shaft 61 and the main shaft 31 to rotate. The power unit 7 can control the drive shaft 61 and the main shaft 31 to rotate at different speeds. Usually, the speed of the drive shaft 61 is lower than the speed of the main shaft 31 so that the classifying impeller 6 can effectively classify the powder.

[0019] Combined with appendix Figure 2 and attached Figure 3As shown, the power unit 7 includes two parallel rotating shafts 71 installed inside the crushing body 1. These two rotating shafts 71 are rotatably connected to the inner wall of the crushing body 1 and are connected to each other via a belt drive mechanism 72. One of the rotating shafts 71 is fixedly mounted with a first driving gear 73 and a second driving gear 74. An energy-saving servo motor 75 is also fixedly mounted on the crushing body 1. The output end of the servo motor 75 is fixedly connected to the other rotating shaft 71, which is the shaft 71 without the first driving gear 73 and the second driving gear 74. A gear is fixedly mounted on the main shaft 31. A driven gear 76 meshes with a driving gear 73, while a driven gear 77 meshes with a driving gear 74 on the transmission shaft 61. It should be further noted that the radius and number of teeth of the driving gear 73 are larger than those of the driven gear 76, while the radius and number of teeth of the driving gear 74 are smaller than those of the driven gear 77. Therefore, during power transmission, energy-saving transmission can be effectively achieved. Utilizing the principle of gear transmission, power can be used more efficiently during transmission, reducing energy loss. (Combined with attached...) Figure 1 As shown, when the equipment is in operation, the material enters the area between the crushing disc 3 and the toothed disc 4. Here, the material is subjected to strong impact, shearing and friction, which continuously crushes the material until it is finally crushed into ultrafine powder. After crushing, the material is screened by the classifying impeller 6. After screening, the material that meets the requirements enters the cyclone separator 9. The cyclone separator 9 can further separate and collect the material. The dust generated in the whole process is treated by the pulse dust collector 10, which can effectively capture and treat the dust, ensuring the cleanliness of the working environment and the normal operation of the equipment.

[0020] Below the classifying impeller 6, within the inner space of the diversion ring 22, are multiple inclined plate frames 62, collection frame one 63, and collection frame two 64. These inclined plate frames 62, collection frame one 63, and collection frame two 64 are arranged alternately around the center of the drive shaft 61. A mounting plate frame 65 is fixedly mounted on the drive shaft 61. All inclined plate frames 62, collection frame one 63, and collection frame two 64 are connected to the mounting plate frame 65 via their respective connecting shafts 66. The inclined plate frames 62 are fixedly connected to the connecting shaft 66, while the collection frames one 63 and collection frame two 64 are rotatably connected to the connecting shaft 66. Therefore, when the drive shaft 61 drives the mounting plate frame 65 to rotate, the inclined plate frames 62, collection frame one 63, and collection frame two 64 all revolve around the axis of the drive shaft 61, and the material falls from the feed pipe 21. Subsequently, some material passes directly through the gap between the inclined plate frame 62, the first collection frame 63, and the second collection frame 64, falling into the crushing chamber 5 in the area directly below the feed pipe 21, which is area A. The remaining material is caught by the rotating inclined plate frame 62, the first collection frame 63, and the second collection frame 64. Because the inclined plate frame 62 is designed with a fixed inclination angle, it guides the caught material to the surface of the crushing disc frame 3, with the landing point located near area A, which is area B. This achieves initial dispersion of the material. The first collection frame 63 and the second collection frame 64 are used to transport the caught material to the crushing chamber 5 area away from directly below the feed pipe 21, which is area C. By feeding the material to area C, excessive concentration of material and crushing heat in area A is effectively avoided. Combined with the attached... Figure 2-4 As shown, area A is the area directly below the feed pipe 21, area B is the area near area A, and area C is the area far from area A. Under normal circumstances, since the falling position is fixed, area C processes relatively less material compared to areas A and B, and the area of ​​area C is usually larger.

[0021] To enable the first collection frame 63 and the second collection frame 64 to automatically flip and unload in area C, torsion springs 67 are connected between the first collection frame 63 and the second collection frame 64 and the connecting shaft 66. The torsion springs 67 keep the frames in a horizontal or slightly tilted position when not in operation to facilitate material reception. For the first collection frame 63, a force-bearing rod 68 is fixedly installed at its end, and an L-shaped rod 23 is fixedly installed on the inner wall of the diversion ring 22. Further, the L-shaped rod 23 is installed in the area of ​​the diversion ring 22 away from the feed pipe 21. The specific installation position can be adjusted according to the actual processing conditions, but it is necessary to ensure that the L-shaped rod 23 is located away from the feed pipe 21. When installing the tray frame... When the collecting frame 63 rotates to this position, the force-bearing rod 68 collides with the L-shaped rod 23. The L-shaped rod 23 prevents the force-bearing rod 68 from continuing to move, thereby forcing the collecting frame 63 to overcome the torque of the torsion spring 67 and quickly rotate around the connecting shaft 66, dumping the material it carries into area C. Subsequently, the collecting frame 63 returns to its original position under the action of the torsion spring 67. For the collecting frame 64, the triggering mechanism is different. A movable shaft 69 that can slide axially is provided inside the end of the collecting frame 64. One end of the movable shaft 69 is slidably connected to the inner wall of the connecting shaft 66, and a spring mechanism 60 connects the two, so that the movable shaft 69 can pop outward. Following this trend, the surface of the movable shaft 69 is provided with an arc-shaped groove 691, and a ball 641 is installed on the inner wall of the second collection frame 64. The ball 641 is confined within the arc-shaped groove 691 of the movable shaft 69. An arc-shaped protrusion 24 is fixedly installed on the inner wall of the diverter ring 22. The position of the arc-shaped protrusion 24 is offset from that of the L-shaped rod 23, and is also located in region C but in a different position than the L-shaped rod 23. Relative to the position of the L-shaped rod 23, the arc-shaped protrusion 24 is installed relatively close to region A but still maintains a certain distance. Therefore, when the second collection frame 64 rotates to the position of the arc-shaped protrusion 24, the ball at the end of the movable shaft 69 will contact the arc-shaped protrusion 24. The protrusion 24 forces the movable shaft 69 to compress and slide into the connecting shaft 66. As the movable shaft 69 slides, the arc-shaped groove 691 on its surface applies force to the ball 641, thereby driving the entire collection frame 64 to rotate around the connecting shaft 66 to achieve overturning and unloading. The material is thus unloaded at the C area position corresponding to the arc-shaped protrusion 24. After triggering, each component is reset under the action of the spring mechanism 60 and the torsion spring 67. By setting multiple sets of collection frames 63 and 64, the material falling from the feed pipe 21 is dynamically and evenly dispersed to the entire circumference of the crushing chamber 5 for crushing, fundamentally solving the overheating problem caused by the concentration of material and heat in a local area.

[0022] Below the mounting plate 65, a ring plate 8 is fixedly mounted on the drive shaft 61. Below the ring plate 8, a positioning plate 81 is fixedly connected to the inner wall of the diverter ring 22 via a connecting rod 82. The positioning plate 81 is fixedly connected to the diverter ring 22. Inside the positioning plate 81, a transmission plate 83 is rotatably mounted via a bearing (not shown in the figure). The inner wall of the transmission plate 83 does not contact the drive shaft 61. An electromagnetic mechanism 84 is fixedly mounted on the top of the transmission plate 83. Multiple sliding holes (not shown in the figure) are opened radially on the transmission plate 83. A guide shaft 85 is slidably mounted in each sliding hole. The upper end of the guide shaft 85 is located above the electromagnetic mechanism 84, and the lower end is located above the crushing plate 3. Further explanation The outer wall of the guide shaft 85 does not contact the inner wall of the electromagnetic mechanism 84. Iron sleeves 86 are fixedly installed at both ends of the guide shaft 85. When the electromagnetic mechanism 84 is energized, it can generate a magnetic attraction force on the iron sleeves 86 located above it. Multiple sets of corresponding through holes 87 are opened on both the crushing disc frame 3 and the annular disc frame 8. A connecting disc frame 89 is provided below the transmission disc frame 83, and the connecting disc frame 89 is fixedly connected to multiple guide shafts 85. Multiple arc-shaped rod frames 80 are fixedly installed on the connecting disc frame 89, and cleaning rod frames 801 are fixedly installed at the ends of the arc-shaped rod frames 80. In the initial state, the electromagnetic mechanism 84 is de-energized. Under the action of the return spring 88 connected between the transmission disc frame 83 and the inner wall of the guide shaft 85, the upper end of the guide shaft 85... The iron sleeve 86 is inserted into the through hole 87 of the annular disc frame 8. At this time, the return spring 88 is in normal condition, and preferably a return spring 88 with a large elastic coefficient. The lower iron sleeve 86 is suspended above the crushing disc frame 3. Since the upper end of the guide shaft 85 is inserted into the through hole 87 of the annular disc frame 8, the transmission disc frame 83 and the connecting disc frame 89, the arc rod frame 80 and the cleaning rod frame 801 fixed thereto will rotate together with the transmission shaft 61. The cleaning rod frame 801 is located above the crushing chamber 5. The rotating arc rod frame 80 and the cleaning rod frame 801 can play an auxiliary role in dispersing and guiding the falling material, further promoting the uniform distribution of material. When it is necessary to clean the material that may accumulate on the inner wall of the crushing chamber 5, the control electromagnetic mechanism 84 is energized. The magnetic force generated by 84 attracts the upper iron sleeve 86, causing the guide shaft 85 to move downwards against the force of the return spring 88. This causes the upper iron sleeve 86 to disengage from the through hole 87 of the annular disc frame 8, while the lower iron sleeve 86 moves down and inserts into the through hole 87 of the crushing disc frame 3. At this point, the drive source is switched, and the transmission disc frame 83, connecting disc frame 89, arc-shaped rod frame 80, and cleaning rod frame 801 are now driven by the high-speed rotating crushing disc frame 3. The cleaning rod frame 801 then rotates at high speed into the crushing chamber 5 to scrape and clean the inner wall of the chamber, effectively preventing the material from gelatinizing due to long-term retention and ensuring a continuous low-temperature crushing effect. The cleaning rod frame 801 is designed with an arc-shaped inclined shape, which is more conducive to cutting into the material layer and scraping off the accumulated material.Because the crushing disc 3 uses surface crushing components and the toothed disc 4 to crush the black fungus, when the cleaning rod 801 enters the crushing chamber 5 and moves synchronously with the crushing disc 3, the cleaning rod 801 will not come into contact with the crushing components on the crushing disc 3, thus avoiding interference.

[0023] Specifically, dried black fungus in block or flake form is continuously and quantitatively fed into the crushing tank 2 through the feed pipe 21 via an external screw conveyor system. The servo motor 75 is then activated, and its output drives two rotating shafts 71 via a belt drive mechanism 72. On one of the rotating shafts 71, the first driving gear 73 and the second driving gear 74 respectively drive the first driven gear 76 and the second driven gear 77, thereby driving the main shaft 31 and the transmission shaft 61 to rotate. The main shaft 31 drives the crushing disc 3 to rotate at high speed, performing the primary crushing action. The transmission shaft 61 drives the grading impeller 6 and the mounting disc 65 and annular disc 8 mounted on it to rotate at a relatively low speed. After the material enters the crushing tank 2, it falls freely under the action of gravity. It first enters the annular space defined by the diversion ring 22. Part of the material passes directly through the gap between the rotating inclined plate frame 62, the first collection frame 63 and the second collection frame 64 and falls into area A. The other part of the material is intercepted by the rotating inclined plate frame 62, the first collection frame 63 and the second collection frame 64. Due to its fixed inclination angle, the inclined plate frame 62 will immediately "sweep" the received material out along the inclined surface and make it fall into area B near area A. The first collection frame 63 and the second collection frame 64 collect the material and rotate with the installation plate frame 65 along with the material. When the material-containing collection frame 63 rotates to region C, the force-bearing rod 68 approaches the L-shaped rod 23 until it contacts it. Then, the force-bearing rod 68 at the end of the collection frame 63 collides with the L-shaped rod 23 fixed to the inner wall of the diversion ring 22. The L-shaped rod 23 forcibly blocks the force-bearing rod 68, forcing the entire collection frame 63 to rapidly rotate around the connecting shaft 66 at a certain angle. The specific angle can be set according to actual conditions, "scattering" all the material contained within into the crushing chamber 5C1 region at this specific point. Region C1 is a certain area within region C. Subsequently, the collection frame 63 quickly resets under the action of the torsion spring 67, returning to its normal posture and preparing to receive material again. Similarly, when the material-containing collection frame 64 rotates to another preset position within region C that is offset from the previous position—to be further explained, this other preset position refers to an arc-shaped… The installation position of the protrusion 24 is not the same as that of the L-shaped rod 23 and the arc-shaped protrusion 24. Therefore, during the operation, the specific installation of the L-shaped rod 23 and the arc-shaped protrusion 24 needs to be set according to the actual situation. The ball on the movable shaft 69 at its end will contact the arc-shaped protrusion 24 fixed on the inner wall of the diversion ring 22 at this position. The arc-shaped protrusion 24 forces the movable shaft 69 to slide inward. Through the cooperation of the arc-shaped groove 691 on its surface and the ball 641 in the second collection frame 64, the axial movement is converted into the rotational movement of the second collection frame 64, so that the second collection frame 64 flips and "pours" the material into the crushing chamber 5C2 area at this specific point. The C2 area is another area of ​​the C area, which is a certain distance from the C1 area. After triggering, the movable shaft 69 is reset under the action of the spring mechanism 60, and the second collection frame 64 is also in normal state under the action of the torsion spring 67. Through multiple sets of collection frames 63 and 64, as well as L-shaped rods 23 and arc-shaped protrusions 24, the material flow falling from the feed pipe 21 is "divided into smaller parts" and delivered in batches, at fixed points, and evenly to various discrete positions around the circumference of the crushing chamber 5. This allows the material and the impact, shearing, and friction of the crushing load to be evenly distributed throughout the annular crushing chamber, and the heat generated by crushing is also evenly dispersed. Thus, ultra-fine crushing is achieved in a "low-temperature" environment where the heat-sensitive components of black fungus, such as polysaccharides and proteins, are protected from heat damage. The material, evenly distributed on the entire surface of the crushing disc 3, is thrown into the crushing chamber 5 by the powerful centrifugal force generated by the high-speed rotating crushing disc 3. It is violently crushed in the narrow gap between the crushing disc 3 and the toothed disc 4. The powder formed after crushing moves upward under the airflow generated by the system's induced draft fan. When it reaches the top classifying impeller 6, the classifying impeller 6 sets a "cutting particle size" through the centrifugal force field generated by its rotation speed control. The qualified fine powder smaller than this particle size is subjected to a centrifugal force less than the airflow drag force and can pass through the gap between the blades of the classifying impeller 6. It is captured by the subsequent cyclone separator 9 or pulse dust collector 10 and becomes the product. The coarse particles that do not meet the fineness requirements are subjected to a centrifugal force greater than the airflow drag force and are thrown back into the crushing chamber 5 below by the classifying impeller 6. They are mixed with the continuously supplied fresh material and continue to be crushed until they are qualified and separated. This classification cycle ensures the consistency of product particle size. During the crushing operation, the electromagnetic mechanism 84 is usually de-energized. At this time, the cleaning rod 801 rotates at low speed with the transmission shaft 61 under the action of the aforementioned transmission components (arc-shaped rod 80, connecting disc 89, guide shaft 85, and annular disc 8). The cleaning rod 801 rotates above the crushing chamber 5, and its arc-shaped rod 80 can assist in dispersing the falling material. After the equipment has been running for a period of time, to prevent the slight adhesion and accumulation of ultrafine powder on the inner wall of the chamber, the self-cleaning mode can be activated: the electromagnetic mechanism 84 is energized, generating magnetic force to attract the iron sleeve 86 at the upper end of the guide shaft 85 downwards, causing it to... The cleaning rod 801 disengages from the through hole 87 of the annular disc 8, while the iron sleeve 86 at the lower end of the guide shaft 85 moves down and inserts into the through hole 87 of the high-speed rotating crushing disc 3. This connection switch instantly changes the drive source of the cleaning rod 801 from the low-speed transmission shaft 61 to the high-speed crushing disc 3. The cleaning rod 801 is then driven by the crushing disc 3 and rotates into the crushing chamber 5 at an extremely high speed, thoroughly removing any possible slight accumulation or caking, and carrying it away through the material flow. This process is fast and effective, avoiding frictional heating, gelatinization, and uneven particle size caused by material accumulation, ensuring long-term operational stability and product quality.

[0024] The processing technology of a pulverizing device for processing ultrafine low-temperature black fungus powder specifically includes the following steps: S1. The dried black fungus block or flake material is continuously and evenly fed into the crushing tank 2 through the feeding pipe 21. S2. Start the power unit 7 to drive the crushing disc frame 3 to rotate at high speed, while simultaneously driving the classifying impeller 6 and the mounting disc frame 65 to rotate at low speed. Part of the falling material falls directly into the central area near the crushing disc frame 3, while the rest is intercepted by the rotating inclined plate frame 62, the first collection frame 63, and the second collection frame 64. The inclined plate frame 62 guides the material it receives to the central peripheral area of ​​the crushing disc frame 3. When the first collection frame 63 and the second collection frame 64 rotate with the mounting disc frame 65 and reach the preset L-shaped rod frame 23 or arc-shaped protrusion 24 position on the diversion ring 22, they are triggered to flip over, and the material they carry is scattered to the edge area of ​​the crushing disc frame 3. S3. The material dispersed in different radial and circumferential positions of the crushing disc 3 enters the crushing chamber 5 under high-speed centrifugal action. It is fully impacted, sheared and rubbed between the crushing disc 3 and the toothed disc 4 to achieve ultra-fine crushing. The crushed powder rises under the drive of airflow and is classified by particle size by the classifying impeller 6. The qualified fine powder is collected as the product, and the unqualified coarse powder is thrown back to the crushing chamber 5 by the classifying impeller 6 for further crushing. S4. After the continuous crushing operation reaches the preset time, or when the crushing efficiency is detected to have decreased, the control electromagnetic mechanism 84 is energized to generate magnetic force and attract the iron sleeve 86 at the upper end of the guide shaft 85. This causes the guide shaft 85 to slide downward against the resistance of the return spring 88, causing the upper iron sleeve 86 to disengage from the through hole 87 of the annular disc frame 8. At the same time, the lower iron sleeve 86 is inserted downward into the corresponding through hole 87 of the crushing disc frame 3. The cleaning rod frame 801 is then driven by the crushing disc frame 3 and rotates into the crushing chamber 5 at the same high speed as the crushing disc frame 3. Its arc-shaped inclined blade forcefully scrapes the inner wall of the crushing chamber 5 and the surface of the toothed disc 4, completely peeling off and breaking up the attached or accumulated fine powder and flakes, which are then carried out by the continuous airflow and material flow. S5. After the cleaning operation continues for a preset time, the electromagnetic mechanism 84 is de-energized, the magnetic force disappears, and the guide shaft 85 is reset under the action of the reset spring 88. The upper iron sleeve 86 is reinserted into the through hole 87 of the annular disc frame 8, and the lower iron sleeve 86 is pulled out from the through hole 87 of the crushing disc frame 3. The cleaning rod frame 801 then rises and exits the crushing chamber 5, returning to the auxiliary guiding state.
