Technical Field
[0001] This invention belongs to the field of crushing device technology, and in particular relates to a crushing device for raw materials used in the preparation of Dendrobium officinale wine. Background Technology
[0002] Dendrobium spp., a general term for plants of the genus Dendrobium in the family Orchidaceae, is a traditional and precious Chinese medicinal herb. It possesses properties of nourishing yin and clearing heat, nourishing the stomach and promoting fluid production, and tonifying the kidneys and replenishing essence. It also plays a role in enhancing human immunity and preventing early-stage cancer. Dendrobium is more effective when taken in powder form. However, the stems of Dendrobium are rich in polysaccharides, which are sticky at room temperature. Furthermore, the cellulose structure is intact and highly resilient, presenting the following prominent problems during the pulverization process: direct pulverization not only fails to guarantee pulverization quality but also results in insufficient pulverization efficiency; the localized high temperatures generated by mechanical pulverization can easily lead to the thermal decomposition or oxidation of heat-sensitive components such as polysaccharides and glycosides, halving the efficacy of the Dendrobium powder and causing raw material waste. Therefore, how to effectively protect the effective components of Dendrobium while improving pulverization efficiency is a technical challenge that urgently needs to be solved in the field of Dendrobium pulverization technology. To reduce the grinding temperature and protect heat-sensitive components, existing technologies have developed a variety of low-temperature grinding solutions, whose cooling settings can be mainly summarized into the following four categories; The first type is external wall jacketed indirect cooling, which is currently the most widely used low-temperature pulverization solution. The second type is single-sided spray cooling above the conveyor line. This solution is mainly used in screw conveyors or linear screw feeders. The third type: pre-cooling tank atomization cooling, which uses an independent pre-cooling tank as a pretreatment device; The fourth type involves injecting coolant during the pulverization process. This method does not involve pretreatment but directly injects coolant such as liquid nitrogen or dry ice during the ultrafine pulverization process to cool the heat-generating grinding parts in time. In terms of low-temperature embrittlement technology, pretreatment of polysaccharides and cellulose in Dendrobium is carried out through nitrogen freezing and static pressure: dried Dendrobium is cut into 0.2-1cm segments, dried to a moisture content of 7%-10% by weight, placed in a sealed container and frozen with liquid nitrogen for 20-300 seconds, then subjected to high pressure treatment at 0.8-3MPa for 1-5 minutes, followed by rapid decompression to normal pressure, and then ultrafine crushing using conventional equipment. In this method, nitrogen freezing increases the embrittlement of the material, rapid cooling reduces the viscosity of polysaccharides and the toughness of cellulose, and high pressure treatment reduces the embrittlement of cellulose. The method involves microscopic fracture of Dendrobium officinale particles, resulting in a cumulative yield of 86.4% of particles ≤10μm and 97.2% of particles ≤15μm. This method significantly improves the subsequent pulverization effect through pretreatment. However, both nitrogen freezing and high-pressure treatment are carried out in steps in a closed container, resulting in a long processing cycle (freezing + high pressure takes 1-5 minutes or more). It is a batch processing method rather than a continuous processing method, requiring a large equipment footprint and making it difficult to integrate with the pulverization chamber. There are also issues of material transfer and temperature rise between pretreatment and pulverization. Regarding the feeding structure, existing Dendrobium pulverizing devices mostly adopt a conical funnel-shaped feeding inlet. After the Dendrobium stems are cut into segments, the length is 0.2-1cm. Under the action of gravity, they naturally accumulate in the funnel, with only the surface material exposed. The Dendrobium inside and at the bottom is covered by the upper material and cannot come into contact with the liquid nitrogen sprayed from above. At the same time, the stems tend to form a "bridging structure" at the neck of the funnel—the stems support each other to form an arch. When liquid nitrogen is sprayed, it only touches a few stems at the top of the arch, and the Dendrobium below the arch does not come into contact with the liquid nitrogen at all. This problem of freezing dead zones caused by material accumulation is a long-standing technical problem that has not been effectively solved when the existing conical funnel feeding structure is applied to low-temperature freezing pretreatment.
[0003] In summary, existing Dendrobium pulverization technologies have the following shortcomings in the low-temperature pretreatment stage: poor freezing uniformity, material accumulation due to the conical funnel structure, difficulty in covering all materials with the freezing medium, and unstable freezing effect. Summary of the Invention
[0004] This invention addresses the problems of poor freezing uniformity, material accumulation due to the conical funnel structure, difficulty in covering all materials with the freezing medium, and unstable freezing effect in existing technologies, and proposes the following technical solution: A raw material crushing device for preparing Dendrobium officinale wine includes a support, a crushing chamber installed at one end of the support, a feeding hopper connected to the feeding end of the crushing chamber, and a crushing structure set on the crushing chamber. The feeding hopper is fitted with a full-flow refrigeration component at its discharge end. The comprehensive shunt freezing assembly includes: The precooling frame is snapped into the inside of the discharge end of the feed hopper, and a mixing groove is provided in the middle of it; Four partition plates are snapped into the inside of the mixing tank. Each partition plate has a guide plate and a partition frame connected to its top in sequence, and a vertical flow channel is formed between adjacent partition frames. A diversion plate is installed on the two partition frames located in the middle. A gas guide pipe is installed at the bottom of the precooling frame, and its gas outlet is connected to the diversion chamber opened inside the partition plate. Circular holes are opened on both sides of the partition plate. Rotary rollers are rotatably mounted inside the precooling frame, and air outlet channels are provided on their outer circumferential sides. The rotating rollers are connected by an internal sawtooth belt linkage structure. A drive motor is fixed to the bottom end of the precooling frame, and its output shaft is engaged with one of the rotating rollers. An air inlet pipe is located inside the precooling frame, and its air inlet end is used to connect to a cold source.
[0005] As a preferred embodiment of the above technical solution, the crushing structure is composed of a stepper motor and a cutting blade. The stepper motor is installed at the top of the crushing chamber and its output shaft extends into the inside of the crushing chamber. Multiple cutting blades are connected to the outside of the output shaft by keying.
[0006] As a preferred embodiment of the above technical solution, a screen is fixedly installed at the bottom of the outer surface of the crushing chamber.
[0007] As a preferred embodiment of the above technical solution, the feed hopper is conical, with its top diameter being larger than its bottom diameter.
[0008] As a preferred embodiment of the above technical solution, three sides of the inner wall of the mixing tank are provided with vent holes, and the other side is provided with a groove. The precooling frame has a connecting plate attached to the top of the groove. The rotating roller is sleeved on the outside of the inner limiting roller fixed at the bottom of the connecting plate. The inner limiting roller is hollow and has an air outlet on the side facing the mixing channel.
[0009] As a preferred embodiment of the above technical solution, a gas-gathering tube is installed on the end face of the gas guide tube. The gas-gathering tube is composed of two rectangular tubes and one circular tube, wherein the two rectangular tubes penetrate the interior of the gas guide tube; and the bottom ends of the four inner limiting rollers are provided with slots corresponding to the top ends of the circular tubes, and are fixedly connected to the top ends of the circular tubes.
[0010] As a preferred embodiment of the above technical solution, the partition plate has multiple circular holes on both sides, which are evenly distributed along the height direction of the partition plate, and the air outlet channel on the outside of the rotating roller is a plurality of strip grooves or circular holes distributed circumferentially.
[0011] As a preferred embodiment of the above technical solution, the internal sawtooth belt linkage structure is a synchronous belt or an internal toothed belt that meshes with the gears or pulleys at the ends of each rotating roller.
[0012] As a preferred embodiment of the above technical solution, the cold source is liquid nitrogen or compressed cooling gas, and a sealing ring is provided between the precooling frame and the discharge end of the feed hopper.
[0013] The beneficial effects of this invention are as follows: (1) By setting four partition plates and the partition frame on top of the precooling frame, multiple vertical flow channels are formed between adjacent partition frames, so that the Dendrobium raw material is orderly divided into multiple independent material flows when it enters the precooling frame. The setting of the flow guide plate further guides the material in the middle to flow to both sides, ensuring that the material volume in each channel is balanced. The flow guide structure effectively avoids the accumulation and entanglement of materials during the feeding process, so that each Dendrobium stem can pass through the cooling area in an upright posture and independently, creating conditions for subsequent uniform cooling. (2) Ventilation holes are opened on three sides of the inner wall of the precooling frame mixing tank. Combined with the round holes on both sides of the partition plate and the air outlet channel of the rotating roller, a multi-directional and multi-layer three-dimensional cooling airflow field is formed. After the cold source gas enters the precooling frame through the air inlet pipe, part of it directly cools the material through the ventilation holes, another part enters the flow distribution chamber of the partition plate through the gas guide pipe, and then cools the material from both sides through the round holes; another part enters the inner limiting roller through the gas gathering pipe, and finally exits from the air outlet channel of the rotating roller to cool the material at close range. The three cooling paths work simultaneously to ensure that all surfaces of the material can be fully covered by the cooling medium, and the freezing uniformity is significantly improved. (3) A rotating roller is driven by a drive motor, and then all rotating rollers are driven to rotate synchronously through the internal sawtooth belt linkage structure. While the air outlet channel on the outside of the rotating roller discharges the cooling gas, it drives the contacting Dendrobium stem to rotate through friction. The material continues to roll during the cooling process, so that each surface of it is exposed to the cooling airflow in turn, which further improves the uniformity of freezing. At the same time, the rotation causes the Dendrobium fiber to be subjected to continuous mechanical disturbance at low temperature, which is conducive to the breakage of the cellulose microstructure and the embrittlement effect is more significant.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Example
[0017] This invention provides a raw material crushing device for the preparation of Dendrobium officinale wine, such as... Figures 1 to 6 As shown, it includes a support frame 1, a crushing chamber 3, a feeding hopper 2, a crushing structure 5, and a fully diverting freezing assembly 6; The support frame 1 serves as the foundation for the entire device. A crushing chamber 3 is fixedly installed at one end of the support frame 1. The crushing chamber 3 has a cylindrical structure and is hollow inside. It is used to accommodate the crushing structure 5 and to crush the Dendrobium officinale raw material. The feed end (i.e. the upper end) of the crushing chamber 3 is connected to the feed hopper 2. The feed hopper 2 is conical in shape, with the diameter of the top end being larger than the diameter of the bottom end. This design is conducive to the Dendrobium officinale raw material falling naturally into the crushing chamber 3 under the action of gravity. A screen 4 is fixedly installed at the bottom of the outer surface of the grinding chamber 3. The screen 4 is used to screen the pulverized Dendrobium powder. Powder that meets the fineness requirements is discharged and collected through the screen 4, while particles that do not meet the fineness requirements remain in the grinding chamber 3 for further pulverization. The crushing chamber 3 is equipped with a crushing structure 5, which is composed of a stepper motor and a cutting blade. The stepper motor is installed at the top of the crushing chamber 3, and its output shaft penetrates vertically downward into the interior of the crushing chamber 3. Multiple sets of cutting blades are installed on the outside of the output shaft by keying. The cutting blades rotate at high speed with the output shaft to cut, shear and impact the Dendrobium raw material entering the crushing chamber 3 to achieve the crushing operation. The discharge end (i.e. the lower end) of the feed hopper 2 is fitted with a fully diverting freezing component 6. The fully diverting freezing component 6 is used to divert, guide, freeze, and pre-treat the Dendrobium raw material before it enters the crushing chamber 3.
[0018] The fully diverted freezing assembly 6 includes a precooling frame 61, which is snapped into the discharge end of the feed hopper 2. The precooling frame 61 has a rectangular frame structure and is hollow inside. A mixing channel 62 is provided in the middle of the frame. The mixing channel 62 is a hollow cavity inside the precooling frame 61, which is used to hold the Dendrobium officinale raw material and provide cooling space. In the inner wall of the mixing tank 62 of the precooling frame 61, three sides (e.g., the left side, the right side and the rear side) are provided with vent holes, and another side (the front side) is provided with a groove. The vent holes are a densely distributed microporous structure, which allows cooling gas to enter the interior of the mixing tank 62 through the vent holes and come into contact with the Dendrobium raw material for cooling. A sealing ring is provided between the precooling frame 61 and the discharge end of the feed hopper 2 to ensure the sealing of the connection and prevent the leakage of cooling gas; Four partition plates 63 are snapped into the mixing tank 62 of the precooling frame 61. The four partition plates 63 are arranged in parallel at equal intervals along the width direction of the mixing tank 62, dividing the interior of the mixing tank 62 into multiple independent areas. Each partition plate 63 is fitted with a guide plate 64 at its top to guide the falling Dendrobium raw material to disperse to both sides. Each of the four guide plates 64 has a partition frame 65 fixedly installed at its top. The partition frame 65 is composed of an installation strip and multiple rectangular plates. The installation strip is horizontally arranged along the arrangement direction of the partition plates 63, and the multiple rectangular plates are vertically fixed on the installation strip. A vertical flow channel is formed between two adjacent rectangular plates. The width of the vertical flow channel is slightly larger than the diameter of the Dendrobium stem, so that the Dendrobium stem can only pass through the channel in an upright posture, thereby realizing the vertical orientation of the material. Two partition frames 65 located in the middle of the mixing tank 62 are equipped with flow guide plates 66. The flow guide plates 66 connect the two partition frames 65 in the middle with two other guide plates 64. They are used to guide the Dendrobium after the material in the middle is vertically divided, prevent it from entering the sides, and ensure that the amount of material in each vertical flow channel is balanced. Multiple gas guide pipes 67 are symmetrically installed at equal intervals at the bottom of the precooling frame 61. Two gas guide pipes 67 form a group. The gas guide pipes 67 extend vertically downwards, with their inlet end connected to the inside of the precooling frame 61 and their outlet end connected to the diversion chamber 68 opened inside the partition plate 63. Specifically, the interior of the partition plate 63 is hollow, forming two flow chambers 68. The outlet end of the gas guide pipe 67 is inserted into the interior of the partition plate 63 and connected to the flow chambers 68. Circular holes are opened on both sides of the partition plate 63 (i.e., the two sides facing the material flow channel). There are multiple circular holes, which are evenly distributed along the height direction of the partition plate 63, so that the cooling gas in the flow chambers 68 can be evenly sprayed to both sides through the circular holes and directly act on the Dendrobium raw material passing through the vertical flow channel. A gas concentrator 69 is installed on the end face of the gas guide pipe 67. The gas concentrator 69 is composed of two rectangular pipes and one circular pipe. The two rectangular pipes are inserted into the gas guide pipe 67 from both sides and pass through the interior of the gas guide pipe 67. The circular pipe is perpendicularly connected to the two rectangular pipes to form a three-way structure. The gas concentrator 69 is used to divert part of the cooling gas in the gas guide pipe 67 and guide it to the gas supply system of the rotating roller 613. A connecting plate 611 is snapped onto the top of the groove of the precooling frame 61. The connecting plate 611 is long and strip-shaped, and is set along the length of the precooling frame 61. Its length matches the width of the mixing channel 62. The interior of the connecting plate 611 is hollow. Several inner limiting rollers 614 are fixedly installed at equal intervals at the bottom end of the connecting plate 611. The top of the inner limiting rollers 614 penetrates through the interior of the connecting plate 611. The inner limiting rollers 614 are vertically arranged cylindrical structures with hollow interiors to form airflow channels. The inner limiting rollers 614 have air outlets on the side facing the mixing tank 62 (i.e., the side facing the material flow channel) to discharge internal cooling gas. A rotating roller 613 is rotatably connected to the outer side of several inner limiting rollers 614. The rotating roller 613 is sleeved on the outside of the inner limiting rollers 614 with a clearance fit, so that the rotating roller 613 can rotate freely around the inner limiting rollers 614. The outer circumferential side of the rotating roller 613 is provided with an air outlet channel, which can be multiple strip grooves or round holes distributed along the circumferential direction, for further diffusion of the cooling gas discharged from the inner limiting rollers 614 to the material surface. Several rotating rollers 613 are connected by an internal sawtooth belt linkage structure 612. The internal sawtooth belt linkage structure 612 is an internal toothed belt that meshes with the gears at the ends of each rotating roller 613. When one of the rotating rollers 613 rotates, the internal sawtooth belt linkage structure 612 drives all the rotating rollers 613 to rotate synchronously in the same direction. The bottom of the four inner limiting rollers 614 is provided with slots 615 at the top of the circular tube of the gas gathering tube 69, and the slots 615 are fixedly connected to the top of the circular tube. The cooling gas in the gas gathering tube 69 can enter the interior of the four inner limiting rollers 614 through the slots 615, and then enter the interior of the other inner limiting rollers 614 through the airflow channel inside the connecting plate 611 (the hollow inside the connecting plate 611). A drive motor 610 is fixedly installed at the bottom of the precooling frame 61. The output shaft of the drive motor 610 is connected to one of the rotating rollers 613 to drive the rotating roller 613 to rotate. The drive motor 610 is preferably a low-speed motor to ensure that the material has enough residence time for freezing and cooling. An air inlet pipe 616 is provided inside the precooling frame 61. The air inlet end of the air inlet pipe 616 extends outside the precooling frame 61 for connection to a cold source. The cold source can be a liquid nitrogen tank or a compressed cooling gas supply device. When liquid nitrogen is used as the cold source, the liquid nitrogen vaporizes in the air inlet pipe 616 to form low-temperature nitrogen gas (temperature approximately -50°C to -100°C), which enters the precooling frame 61 for cooling. Working principle: The Dendrobium raw material that has been cut into sections is fed into the top of the feed hopper 2. Under the action of gravity, the Dendrobium raw material slides down the conical inner wall of the feed hopper 2 and enters the discharge end of the feed hopper 2. After the Dendrobium raw material enters the precooling frame 61 of the fully diverted freezing component 6, the width of the vertical flow channel formed between the adjacent rectangular plates of the separator 65 is slightly larger than the diameter of the Dendrobium stem. When the Dendrobium stem passes through this channel, it is forced to adjust to an upright posture (i.e., the long axis of the stem is aligned with the falling direction). This vertical orientation exposes the maximum surface area of the Dendrobium stem to the cooling airflow, which is beneficial to improving cooling efficiency. Then, it contacts the guide plate 66 and the flow guide plate 64. The guide plate 66 guides the material in the middle to both sides, and the flow guide plate 64 further guides and diverts the material to the Dendrobium, so that the material falls evenly into the vertical flow channel between the four separator plates 63. At this time, the cold source is activated, and the low-temperature cooling gas generated by the cold source (low-temperature nitrogen gas formed by liquid nitrogen vaporization or compressed cooling gas) enters the pre-cooling frame 61 through the air inlet pipe 616; Cooling gas enters the interior of the mixing tank 62 directly through the vent holes on three sides of the inner wall of the mixing tank 62, and performs preliminary cooling of the Dendrobium raw material passing through the vertical flow channel from the side of the material. The cooling gas flows downward and enters the diversion chamber 68 inside the partition plate 63 through the gas guide pipe 67 at the bottom of the precooling frame 61. The cooling gas in the diversion chamber 68 is then sprayed out through the evenly distributed round holes on both sides of the partition plate 63, cooling the Dendrobium raw material from both sides of the material (i.e., the two side walls of the vertical flow channel). Since the round holes are evenly distributed along the height of the partition plate 63, the cooling gas can cover the entire falling stroke of the Dendrobium raw material, achieving full-process cooling. Part of the cooling gas in the gas guide pipe 67 enters the gas gathering pipe 69, and enters the interior of the four inner limit rollers 614 through the circular tube of the gas gathering pipe 69 and the slots 615 at the bottom of the four inner limit rollers 614. The cooling gas flows upward along the inner limit rollers 614, and enters the interior of the remaining inner limit rollers 614 through the airflow channel inside the connecting plate 611. Finally, the cooling gas is discharged through the air outlet on the side of the inner limit rollers 614 facing the mixing groove 62, enters the interior of the rotating roller 613, and is discharged through the circumferential air outlet channel on the outer side of the rotating roller 613, directly acting on the surface of the Dendrobium officinale raw material. Since the rotating roller 613 is located inside the vertical flow channel and is in direct contact with the Dendrobium officinale raw material, the cooling effect of this path is the most direct and efficient. While the cooling gas is being supplied, the drive motor 610 is started. The drive motor 610 drives a rotating roller 613 that is engaged with it to rotate. The rotating roller 613 drives all rotating rollers 613 to rotate synchronously in the same direction through the internal sawtooth belt linkage structure 612. The rotating roller 613 drives the contacting Dendrobium stem to rotate through the friction between its outer surface and the Dendrobium raw material. The Dendrobium raw material continues to tumble during the fall, so that each surface of it is exposed to the cooling airflow in turn, achieving uniform cooling in all directions. Under low temperature (-50℃ to -100℃) conditions, the viscosity of polysaccharides in Dendrobium officinale raw materials is significantly reduced, the toughness of cellulose is weakened, and the overall brittleness of the material increases. At the same time, the rotation of the rotating roller 613 generates continuous mechanical disturbance to Dendrobium officinale fibers, further promoting the breakage of the cellulose microstructure, so that the material has reached a good brittle state before entering the crushing chamber 3. After undergoing comprehensive diversion cooling and rotation embrittlement treatment, the Dendrobium raw material is discharged from the bottom of the pre-cooling frame 61 and falls directly into the crushing chamber 3 (since the comprehensive diversion freezing component 6 is directly connected to the crushing chamber 3, the material does not need to be transferred in the middle). When the stepper motor of the crushing structure 5 is started, it drives the output shaft to rotate at high speed. The multiple sets of cutting blades on the output shaft rotate at high speed accordingly. The cutting blades cut, shear and impact the Dendrobium raw material entering the crushing chamber 3, crushing it into fine particles. The crushed Dendrobium powder falls to the screen 4 at the bottom of the crushing chamber 3 under the action of gravity. Particles that meet the fineness requirements are discharged and collected through the screen 4, while particles that do not meet the fineness requirements remain in the crushing chamber 3 to continue to be crushed until the requirements are met.
