[0002] As a traditional precious Chinese medicinal material, Dendrobium candidum has polysaccharide components with multiple biological activities such as immune regulation, antioxidant and anti-tumor, and has extremely high application value in the fields of medicine, health products and functional foods.

The device structure of this method is simple, but it has problems such as long extraction time (usually 2-3 times of extraction, 1-2 hours each time), high polysaccharide degradation rate (high temperature leads to the breakage of glycosidic bond), large solvent consumption, and insufficient activity retention of heat-sensitive polysaccharides. SUMMARY

[0004] The technical problem to be solved by the present application is that the existing device has the defect of low extraction efficiency in the prior art. Therefore, the present application provides a Dendrobium candidum polysaccharide extraction device.

[0005] In order to achieve the above purpose, the following technical scheme is adopted in the present application: a Dendrobium candidum polysaccharide extraction device, comprising an extraction cylinder, a heating chamber is formed in the inner wall of the extraction cylinder, a steam pipe is fixedly connected to one side of the extraction cylinder, a control assembly is arranged in the extraction cylinder, the control assembly comprises an upper grinding disc and a lower grinding disc, the upper grinding disc and the lower grinding disc are arranged in the extraction cylinder, the upper grinding disc is fixedly connected to the inner wall of the extraction cylinder around, the lower grinding disc is rotatably connected to the extraction cylinder, a plurality of recesses are formed in the bottom of the upper grinding disc and are uniformly distributed, a plurality of convex seats matched with the recesses are fixedly connected to the top of the lower grinding disc, the convex seats are slidably connected to the inner wall of the recesses, and a plurality of screening holes penetrating through the lower grinding disc are formed in the surface of the lower grinding disc. A movement roller is fixedly connected to the bottom of the lower grinding disc, an assembly cylinder is slidably sleeved to the bottom of the movement roller, a return spring is arranged in the assembly cylinder, and an electric motor is arranged at the bottom of the assembly cylinder. A plurality of mounting plates are fixedly connected to the bottom of the lower grinding disc around, a plurality of mounting windows are formed in the surface of the mounting plates, a fixed cylinder is fixedly connected to the inner wall of the mounting window on both sides, a rotating roller is arranged in the fixed cylinder, a coil spring is sleeved to both ends of the rotating roller, a connecting seat is fixedly sleeved to the surface of the rotating roller, and a pushing plate is fixedly connected to one end of the connecting seat close to the center of the extraction cylinder.

[0006] Preferably, a support frame is installed on one side of the extraction cylinder.

[0007] Preferably, a funnel is fixedly connected to the top of the upper grinding disc, and a feeding window penetrating through the middle of the upper grinding disc is provided.

Simultaneously, the unique stirring structure installed at the bottom of the lower grinding disc, utilizing rotating rollers and coil springs, causes the agitator plate to stir the solvent and materials from multiple directions as it rotates and moves up and down with the lower grinding disc, enhancing the mass transfer process, accelerating polysaccharide diffusion, and shortening the dissolution equilibrium time. Furthermore, efficient stirring ensures uniform temperature, reducing the degradation of heat-sensitive polysaccharides and preserving their activity.

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figures 1 to 7As shown, the present invention provides a technical solution: a device for extracting polysaccharides from Dendrobium officinale, including an extraction cylinder 1, a support frame 101 installed on one side of the extraction cylinder 1, a heating chamber 102 opened inside the cylinder wall of the extraction cylinder 1, a steam pipe 103 fixedly connected to one side of the extraction cylinder 1, a control component 2 built into the extraction cylinder 1, the control component 2 including an upper grinding disc 201 and a lower grinding disc 202, both of which are placed inside the extraction cylinder 1, the upper grinding disc 201 is fixedly connected to the inner wall of the extraction cylinder 1 around its perimeter, the lower grinding disc 202 is rotatably connected to the extraction cylinder 1, a funnel 203 is fixedly connected to the top of the upper grinding disc 201, a feed window 204 penetrating through itself is opened in the middle of the upper grinding disc 201, and positioning ring grooves 208 are opened around the lower grinding disc 202. Multiple evenly arranged ball bearings 209 are installed in the groove 208. A fixed ring 210 is fitted around the lower grinding disc 202 and rotates around it. The outer ring wall of the fixed ring 210 is fixedly connected to the inner wall of the extraction cylinder 1. The side of the ball bearings 209 away from the lower grinding disc 202 contacts the inner wall of the fixed ring 210. Multiple evenly distributed grooves 205 are opened at the bottom of the upper grinding disc 201. Multiple protrusions 206 that match the grooves 205 are fixedly connected to the top of the lower grinding disc 202. The protrusions 206 are slidably connected to the inner wall of the grooves 205. Multiple screening holes 207 that penetrate through the lower grinding disc 202 are opened on the surface of the lower grinding disc 202. The upper grinding disc 201 of the control component 2 is stably connected to the inner wall of the extraction cylinder 1. The funnel 203 at its top can guide the material to fall between the upper and lower grinding discs 202 through the feed window 204. The lower grinding disc 202 is rotatably connected to the fixed ring 210 via ball bearings 209. When the motor 217 starts, power is transmitted to the assembly cylinder 212 via the rotating disc 216, driving the motion roller 211 to start rotating the lower grinding disc 202. During the rotation of the lower grinding disc 202, the protrusion 206 on its top will sequentially enter the groove 205 at the bottom of the upper grinding disc 201. At this time, the upper and lower grinding discs 202 are in close contact, and the cooperation between the protrusion 206 and the groove 205 is like countless precise grinding teeth, squeezing and grinding the material. As the lower grinding disc 202 continues to rotate, the protrusion 206 gradually moves away from the groove 205. Under the action of the return spring 213, the lower grinding disc 202 will briefly maintain a small distance from the upper grinding disc 201, and then move closer again. This periodic approach and departure gives the protrusion 206 an impact effect on the basis of grinding. In this way, the Dendrobium officinale raw material is pulverized to a micron-sized particle size under the dual action of grinding and impact. This process completely disrupts the cellular structure of the raw material, allowing the polysaccharides encapsulated within the cells to be released more smoothly. This fundamentally solves the problem in traditional methods where the lack of fine pulverization leads to cell walls hindering polysaccharide dissolution and resulting in low dissolution efficiency. Simultaneously, the pulverized material has a significantly increased specific surface area, greatly increasing the contact area with the solvent. This allows the solvent to penetrate the material more quickly, laying a solid foundation for mass transfer in the subsequent extraction process. This fully aligns with the process optimization logic of improving extraction efficiency through physical pretreatment.

[0021] Meanwhile, a motion roller 211 is fixedly connected to the bottom of the lower grinding disc 202. An assembly cylinder 212 is slidably sleeved at the bottom of the motion roller 211. A return spring 213 is built into the assembly cylinder 212. One end of the return spring 213 is fixedly connected to the bottom of the inner cavity of the assembly cylinder 212, and the other end of the return spring 213 is fixedly connected to the motion roller 211. Multiple guide windows 214 are opened around the assembly cylinder 212 and are evenly distributed around the axis of the assembly cylinder 212. Multiple guide seats 215 are fixedly connected to the bottom of the motion roller 211 and are slidably connected to the inner wall of the guide windows 214. A motor 217 is installed at the bottom of the assembly cylinder 212, and a rotating disk 216 is fixedly connected to the bottom of the assembly cylinder 212. The bottom of the rotating disk 216 is fixedly connected to the output end of the motor 217. The motion roller 211 at the bottom of the lower grinding disc 202 is connected to the assembly cylinder 212 through the return spring 213. This ingenious design provides a strong guarantee for the grinding process. The return spring 213 has good elasticity, ensuring that the lower grinding disc 202 and the upper grinding disc 201 remain in close contact at all times. When the boss 206 enters the groove 205, the lower grinding disc 202 performs stable grinding under the drive of power, ensuring consistent grinding results. When the boss 206 moves away from the groove 205, and the lower grinding disc 202 experiences a slight positional change due to rotation, the return spring 213 promptly pulls the lower grinding disc 202 back, ensuring it is once again in close contact with the upper grinding disc 201. This close contact not only guarantees the continuity and stability of the grinding process but also allows each engagement of the boss 206 and the groove 205 to fully utilize the grinding and impact effects, avoiding problems such as incomplete material crushing caused by loose contact between the grinding discs. This further improves the efficiency and quality of material crushing, providing a higher quality raw material basis for subsequent polysaccharide extraction.

[0022] Furthermore, multiple mounting plates 218 are fixedly connected around the bottom of the lower grinding disc 202. The mounting plates 218 are evenly distributed around the axis of the extraction cylinder 1. Multiple mounting windows 219 are opened on the surface of the mounting plates 218. Fixed cylinders 220 are fixedly connected to both sides of the inner wall of the mounting windows 219. Rotating rollers 221 are built into the fixed cylinders 220. The two ends of the rotating rollers 221 are rotatably connected to the bottom of the inner cavity of the fixed cylinders 220. Coil springs 222 are sleeved on both ends of the rotating rollers 221. One end of the coil springs 222 is fixedly connected to the inner wall of the fixed cylinders 220, and the other end of the coil springs 222 is fixedly connected to the rotating rollers 221. Connecting seats 223 are fixedly sleeved on the surface of the rotating rollers 221. A toggle plate 224 is fixedly connected to the end of the connecting seats 223 near the center of the extraction cylinder 1. A unique stirring structure is installed on the mounting plates 218 around the bottom of the lower grinding disc 202. Inside the fixed cylinder 220 on each mounting plate 218, a rotating roller 221 is connected to the fixed cylinder 220 via a coil spring 222. An actuating plate 224 is fixed to the connecting seat 223 on the surface of the rotating roller 221. When the lower grinding disc 202 rotates under the drive of the motor 217 and moves up and down due to the cooperation of the protrusion 206 and the groove 205, the actuating plate 224 will generate a complex motion trajectory along with the movement of the lower grinding disc 202. On one hand, the rotation of the lower grinding disc 202 drives the actuating plate 224 to rotate around the axis of the extraction cylinder 1, generating a circumferential stirring force on the solvent; on the other hand, the up and down movement of the lower grinding disc 202 causes the actuating plate 224 to oscillate radially. This oscillation is more flexible and complete under the elastic action of the coil spring 222. In this way, the actuating plate 224 can agitate the solvent and the pulverized material from multiple directions, forming a strong water flow disturbance. Compared to the shortcomings of traditional open-top tank stirring, which suffers from insufficient fluid shear force and uneven mass transfer, this optimized stirring design ensures thorough mixing of the solvent and materials, greatly accelerating the diffusion of polysaccharides from the solid to the liquid phase, shortening the time to reach dissolution equilibrium, and significantly enhancing the mass transfer process. Simultaneously, the efficient stirring action allows for uniform heat distribution within the extraction chamber 1, avoiding the localized high-temperature phenomena that easily occur in traditional open-top heating methods. This reduces the problem of glycosidic bond breakage caused by high temperatures and plays a crucial role in preserving the activity of heat-sensitive polysaccharides. This Dendrobium officinale polysaccharide extraction device, through its ingenious structural design, organically combines grinding, stirring, mass transfer, and temperature control. The heating chamber 102 and steam pipe 103 provide a suitable temperature environment for the extraction process. Combined with the grinding action of the control component 2, this achieves efficient cell wall breaking and fine pulverization of the Dendrobium officinale raw material, increasing the contact area between the material and the solvent and improving the polysaccharide release efficiency. The unique stirring design overcomes the shortcomings of traditional stirring methods, enhances the mass transfer process, and improves temperature uniformity, accelerating the extraction process while ensuring the activity of the polysaccharides. The entire device optimizes every step from raw material pretreatment to the extraction process, with each step interconnected and complementary, forming a complete and efficient polysaccharide extraction solution. Compared with traditional extraction methods such as water decoction, this device has significant advantages in polysaccharide dissolution efficiency, extraction quality, and protection of heat-sensitive components, providing strong technical support for the industrial extraction and application of Dendrobium officinale polysaccharides.

[0023] Working principle: I. Material Pretreatment and Grinding / Cell Wall Breaking Mechanism Material import and positioning The raw material is guided through the top funnel 203 and falls between the upper and lower grinding discs 202 through the feed window 204 in the middle of the upper grinding disc 201. The upper grinding disc 201 is fixed to the inner wall of the extraction cylinder 1, and multiple grooves 205 are formed at its bottom; the lower grinding disc 202 is connected to the fixing ring 210 through the ball bearings 209 in the surrounding positioning ring grooves 208, and can rotate around the axis. This structure keeps the lower grinding disc 202 radially stable during rotation, avoiding shaking that could affect the grinding accuracy.

[0024] Dynamic grinding and impact cell disruption After the motor 217 starts, the power is transmitted to the assembly cylinder 212 through the rotating disk 216, driving the motion roller 211 to rotate the lower grinding disk 202. As the lower grinding disk 202 rotates, the protrusion 206 on the top of the lower grinding disk 202 sequentially engages with the groove 205 of the upper grinding disk 201. At this time, the upper and lower grinding disks 202 are tightly fitted, and the protrusion 206 and the groove 205 form a structure similar to "grinding teeth," extruding and shearing the material. When the protrusion 206 rotates out of the groove 205, the lower grinding disk 202 is briefly lifted by the return spring 213, maintaining a small distance from the upper grinding disk 201, and then approaches the groove 205 again, forming a periodic "fitting-separating" motion. This motion causes the protrusion 206 to exert a dual effect of grinding and impacting the material, pulverizing the raw material to the micron level, completely destroying the cell wall structure, and promoting the release of polysaccharides from the cells, solving the problem of low dissolution efficiency caused by insufficient pulverization in traditional methods.

[0025] Elastic recovery and grinding stability The motion roller 211 at the bottom of the lower grinding disc 202 is connected to the assembly cylinder 212 via a return spring 213. The guide windows 214 around the assembly cylinder 212 cooperate with the guide seats 215 of the motion roller 211 to limit its radial displacement. When the boss 206 disengages from the groove 205, the return spring 213 pulls the lower grinding disc 202 back with elastic force, ensuring that the upper and lower grinding discs 202 always maintain close contact, avoiding incomplete material crushing due to excessive gaps, and ensuring the continuity and stability of the grinding process.

[0026] II. Optimization of Stirring Mass Transfer and Temperature Control Multidimensional stirring enhances mass transfer A stirring structure is installed on the mounting plate 218 at the bottom of the lower grinding disc 202: the rotating roller 221 inside the fixed cylinder 220 is connected to the fixed cylinder 220 via a coil spring 222, and the connecting seat 223 on the surface of the rotating roller 221 drives the actuating plate 224. When the lower grinding disc 202 rotates, the actuating plate 224 rotates circumferentially around the axis of the extraction cylinder 1, and also oscillates radially due to the up-and-down movement of the lower grinding disc 202 (the elasticity of the coil spring 222 makes the oscillation more flexible). This compound motion creates strong water flow disturbance, which has a stronger fluid shear force than traditional open tank stirring, enabling the solvent to mix fully with the pulverized material, accelerating the diffusion of polysaccharides from the solid phase to the liquid phase, and shortening the dissolution equilibrium time.

[0027] Temperature uniformity and thermal protection The heating chamber 102 and steam pipe 103 inside the extraction cylinder 1 provide a constant temperature heating environment, while the stirring structure promotes uniform heat distribution, avoiding the localized high temperature phenomenon of traditional open heating. This design not only increases the solubility of polysaccharides by raising the temperature, but also reduces the glycosidic bond breakage caused by high temperature, protecting the activity of heat-sensitive polysaccharides, and balancing extraction efficiency and component stability.

[0028] III. Integrated Collaborative Workflow End-to-end functional collaboration The raw material is introduced into the grinding zone through the funnel 203. Under the grinding and impact action of the protrusion 206 and the groove 205, the cell walls are broken and pulverized, and the specific surface area is greatly increased, laying the foundation for mass transfer for polysaccharide dissolution. The pulverized material is mixed with the solvent, and the multi-dimensional stirring of the agitator 224 enhances the mass transfer process. At the same time, the heating chamber 102 provides a suitable temperature to promote rapid dissolution of polysaccharides. Steam can be introduced into the steam pipe 103 as needed to adjust the temperature and ensure that the extraction process is carried out in the optimal temperature zone.

[0029] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
