Description

Technical Field

[0001] The present application relates to the field of supercritical fluid extraction, and in particular to a Cordyceps sinensis purification machine. Background Art

[0002] The application of supercritical carbon dioxide extraction technology in Cordyceps sinensis purification is primarily due to its ability to effectively extract and separate the active ingredients in Cordyceps sinensis while preserving their activity. In a supercritical state, carbon dioxide has the density and solubility of a liquid, while also possessing the diffusivity of a gas, enabling efficient extraction of the plant's active ingredients.

[0003] An extraction kettle must be used in the extraction process. During the operation, the crushed Cordyceps fruiting bodies will be placed in the basket of the kettle body, and then the basket will be encapsulated in the inner cavity of the kettle body using the kettle cover. By delivering supercritical carbon dioxide into the kettle body, the supercritical carbon dioxide passes through the material, thereby dissolving the active ingredients in the Cordyceps and carrying the active ingredients away to the sub-extraction tank. By reducing the pressure of the extraction tank, the supercritical carbon dioxide is restored to a gaseous state, thereby releasing the active ingredients.

[0004] In the prior art, the basket inside the kettle body is usually provided with multiple sections, and two adjacent baskets are tightly connected by screws. Supercritical carbon dioxide enters the kettle body, usually from the lower end of the kettle body and is output from the top of the kettle body. Supercritical carbon dioxide will pass through the basket along the axial direction of the kettle body. At this time, the raw materials in the lowest section of the basket are easily extracted or completely extracted. After the extraction fluid is gradually saturated from bottom to top, the raw materials in the top basket cannot be effectively extracted, and the resistance of the fluid will be increased. In order to solve this problem, multi-stage countercurrent circulation technology, or gradient pressure control technology with segmented boosting, or rotary extraction tanks are usually used to force the raw materials to tumble, and mechanically assisted mixing technology is used to solve the problem of over-extraction at the bottom and under-extraction at the top. However, the above technical solutions lead to an increase in the use of carbon dioxide during the entire extraction process, and the extraction efficiency has not been significantly improved, resulting in the high cost of extracting the effective ingredients of Cordyceps.

[0005] Therefore, how to design an extraction kettle that reduces the cost of extracting the effective ingredients of Cordyceps and improves the efficiency of Cordyceps purification has become a technical problem that needs to be solved urgently by those skilled in the art.

[0022] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0023] like Figure 1 and Figure 2 As shown, it includes a kettle body 1, the top of the kettle body 1 is provided with a mounting port 15 opening upward, and also includes a kettle cover 16 for sealing the mounting port 15, wherein the kettle cover 16 is provided with an air outlet pipe 14 connected to the inner cavity of the kettle body 1, and the bottom of the kettle body 1 is provided with an air inlet pipe 13 connected to the inner cavity of the kettle body 1, and the inner cavity of the kettle body 1 is also provided with a basket assembly 2 for storing raw materials, wherein the basket assembly 2 is placed into the inner cavity of the kettle body 1 from the mounting port 15.

[0024] It is worth noting that the raw material in this embodiment refers to the crushed powder or crushed particles of Cordyceps sinensis.

[0025] The supercritical extraction fluid can be transported into the inner cavity of the kettle body 1 through the gas inlet pipe 13, pass through the basket assembly 2, and be discharged from the gas outlet pipe 14. In this process, the supercritical extraction fluid can dissolve the effective components in the cordyceps powder, so as to carry the effective components in the cordyceps into the extraction tank. The extraction fluid can be separated from the effective components of the cordyceps by adjusting the pressure and temperature, and then the extracted fluid can be flowed into the inner cavity of the kettle body 1 again to realize the recycling of the extraction fluid.

[0026] It is worth noting that, as shown in Figure 2 , Figure 3 and Figure 4 , the bottom of the inner cavity of the kettle body 1 is provided with a supporting seat 18. The basket assembly 2 is placed into the inner cavity of the kettle body 1 through the opening at the top of the kettle body 1, and then the bottom wall of the basket assembly 2 is placed on the supporting seat 18. The supporting of the basket assembly 2 is completed through the supporting seat 18, and then the kettle cover 16 is covered on the top end of the basket assembly 2. The kettle cover 16 is fixed with the kettle body 1 by using the fixing member, so as to seal the basket assembly 2 in the inner cavity of the kettle body 1.

[0027] Specifically, as shown in Figure 4 and Figure 5 , the fixing member can include a fastening ring 17. The inner wall of the fastening ring 17 extends radially inwardly along the fastening ring 17 and has a pressing stop edge 171. The bottom wall of the pressing stop edge 171 abuts against the top wall of the basket assembly 2. The outer peripheral wall of the fastening ring 17 is provided with external threads. The top of the inner cavity of the kettle body 1 is provided with internal threads. The fastening ring 17 is connected through the external threads and the internal threads, so as to realize the fixation of the kettle cover 16.

[0028] It is worth noting that, as shown in Figure 2 , the outer peripheral wall of the basket assembly 2 is also provided with a separation mechanism 21. The inner cavity of the kettle body 1 is separated into a first chamber 11 and a second chamber 12 by using the separation mechanism 21. The first chamber 11 is in communication with the gas inlet pipe 13. The supercritical extraction fluid entering into the inner cavity of the kettle body 1 is received by using the first chamber 11. The supercritical extraction fluid passing through the basket assembly 2 is received by using the second chamber 12, and then the supercritical extraction fluid is discharged outwardly through the gas outlet pipe 14.

[0029] It is worth noting that the supercritical extraction fluid in the embodiment refers to supercritical carbon dioxide.

[0030] Specifically, as shown in Figure 4 and Figure 5As shown, the separation mechanism 21 includes a plug-in strip 211 and a plug-in rib 212, wherein the plug-in rib 212 is arranged on the peripheral wall of the basket assembly 2 and along the axial direction of the kettle body 1, the plug-in strip 211 is fixedly arranged on the side wall of the inner cavity of the kettle body 1 and along the axial direction of the kettle body 1, and the plug-in strip 211 is provided with a plug-in groove 2111 arranged along the axial direction of the kettle body 1. After the basket assembly 2 is installed in the inner cavity of the kettle body 1, the plug-in rib 212 is plugged into the plug-in groove 2111, thereby separating the inner cavity of the kettle body 1, thereby isolating the first chamber 11 and the second chamber 12. At the same time, the side wall of the plug-in rib 212 abuts against the inner wall of the plug-in groove 2111, guiding the installation of the basket assembly 2 and improving the stability of the basket assembly 2.

[0031] In order to solve the problem of mutual communication between the first chamber 11 and the second chamber 12, in this embodiment, the length of the plug-in strip 211 is greater than the length of the plug-in rib 212, and the peripheral wall of the kettle cover 16 is provided with a compensation rib 162 arranged along the axial direction of the kettle cover 16. When the basket assembly 2 is placed into the inner cavity of the kettle body 1 so that the plug-in rib 212 is plugged into the plug-in groove 2111, the kettle cover 16 is placed on the top of the basket assembly 2. The compensation rib 162 on the kettle cover 16 is plugged into the plug-in groove 2111, and the bottom wall of the kettle cover 16 abuts against the top wall of the basket assembly 2 to form a seal. The top wall of the compensation rib 162 is flush with the top wall of the plug-in strip 211. At this time, the fastening ring 17 is threadedly connected to the kettle body 1, and the clamping rib 171 is used to abut against the top wall of the kettle cover 16, thereby limiting the axial movement of the kettle cover 16 along the kettle body 1 and achieving the fixation of the kettle cover 16. Figure 4 As shown, at this time, the bottom wall of the fastening ring 17 abuts against the top wall of the plug-in strip 211 , thereby completing the separation of the first chamber 11 and the second chamber 12 .

[0032] Further, such as Figure 6 As shown, the bottom wall of the kettle cover 16 is provided with an inwardly recessed sealing groove 163, and a sealing gasket 164 is provided in the sealing groove 163. When the kettle cover 16 is placed on the top of the basket assembly 2, the sealing gasket 164 abuts against the top wall of the basket assembly 2, thereby enhancing the sealing effect.

[0033] like Figure 4 and Figure 6 As shown, the side wall of the kettle cover 16 is further provided with an exhaust port 161 , wherein the exhaust port 161 is used to connect the second chamber 12 with the inner cavity of the kettle cover 16 , and to discharge the supercritical extraction fluid gathered in the second chamber 12 to the outside through the exhaust pipe 14 .

[0034] A conventional basket assembly 2 generally includes one or more sections of a material storage barrel 220, wherein the plurality of material storage barrels 220 are fixed by bolts so that the basket assembly 2 composed of the plurality of material storage barrels 220 is distributed along the axial direction of the kettle body 1. The material storage barrels 220 are used to store the raw materials. Then, a supercritical extraction fluid enters from the air inlet pipe 13, passes through the inner cavity of the material storage barrel 220, and is discharged from the air outlet pipe 14. At this time, the supercritical extraction fluid can flow from bottom to top or from top to bottom. Regardless of which method is used, since the supercritical extraction fluid will gradually become saturated, the raw materials that first contact the supercritical extraction fluid will be over-extracted, and the raw materials that contact the supercritical extraction fluid later will be under-extracted. In order to extract the effective components in the raw materials as much as possible, it is necessary to continuously input the supercritical extraction fluid into the interior of the material storage barrel 220. This continuous input method of the supercritical extraction fluid is also suitable for the gradient pressure control technology of staged pressure increase. The above-mentioned raw material extraction method is likely to result in low raw material extraction efficiency and it is difficult to increase the raw material extraction speed.

[0035] Therefore, the present application optimizes the structure of the basket assembly 2, such as Figure 2 and Figure 5 As shown, the basket assembly 2 includes a plurality of storage mechanisms 22 and a plurality of diverter mechanisms 23, wherein the storage mechanisms 22 and the diverter mechanisms 23 are spaced apart along the axial direction of the kettle body 1, and the diverter mechanisms 23 are fixed to the storage mechanisms 22 on both sides by bolts. In this embodiment, as shown in FIG. Figure 5 As shown, there are three storage mechanisms 22 and two diversion mechanisms 23, wherein both ends of the basket assembly 2 are storage mechanisms 22. At this time, the supercritical extraction fluid entering from the air inlet pipe 13 can pass through the bottom storage mechanism 22, and the supercritical extraction fluid output from the top storage mechanism 22 can be directly output to the outside through the air outlet pipe 14. Figure 8 and Figure 9 As shown, a first diversion channel 231 and a second diversion channel 232 are provided on the diversion mechanism 23. The first diversion channel 231 connects the first chamber 11 with the air inlet end 221 of the storage mechanism 22, and the second diversion channel 232 connects the second chamber 12 with the air outlet end 222 of the storage mechanism 22.

[0036] Through the above arrangement, the supercritical extraction fluid entering the inner cavity of the kettle body 1 from the air inlet pipe 13 can enter the first chamber 11, and the diversion mechanism 23 diverts the supercritical extraction fluid in the first chamber 11, and then enters the air inlet end 221 of each storage mechanism 22 through the corresponding first diversion channel 231. At this time, the supercritical extraction fluid contacts the raw material in the storage mechanism 22, and the supercritical extraction fluid dissolves the effective components in the raw material and flows into the second chamber 12 from the air outlet end 222 of the storage mechanism 22. Finally, the supercritical extraction fluid in the second chamber 12 carries the effective components of the raw material and flows outward from the air outlet pipe 14 of the kettle cover 16 into the extraction tank.

[0037] It is worth mentioning here that the provision of multiple diversion mechanisms 23 allows the raw materials in multiple storage mechanisms 22 to be extracted simultaneously, thereby improving the extraction efficiency of the raw materials. Furthermore, since the conventional basket assembly 2 can only enter the supercritical extraction fluid from one end of the storage barrel 220 and the supercritical extraction fluid can flow out from the other end, the axial length of the basket assembly 2 is relatively large, resulting in problems of over-extraction at the bottom and under-extraction at the top. In this technical solution, the raw materials in the basket assembly 2 are respectively encapsulated in multiple storage mechanisms 22, which can shorten the flow path of the supercritical extraction fluid and realize the simultaneous extraction of raw materials in multiple storage mechanisms 22. Without changing the structure of the kettle body 1 and placing the basket assembly 2 axially along the kettle body 1, the diversion of the supercritical extraction fluid is realized by setting the diversion mechanism 23, thereby achieving efficient extraction of the raw materials.

[0038] Among them, the supercritical extraction fluid enters the first chamber 11 through the air inlet pipe 13, and then is buffered by the first chamber 11. Finally, the supercritical extraction fluid is diverted through the diversion mechanism 23. At this time, the diversion path of the supercritical extraction fluid is increased compared with the existing technology. Therefore, the flow rate of the supercritical extraction fluid entering the first chamber 11 can be increased, the circulation period of the supercritical extraction fluid can be shortened, the utilization efficiency of the supercritical extraction fluid can be improved, and the output of the equipment per unit time can be further increased.

[0039] In this embodiment, if Figure 3 and Figure 7As shown, the supporting seat 18 is annular and fixedly mounted on the bottom side wall of the inner cavity of the kettle body 1, wherein the supporting seat 18 is placed horizontally to support the basket assembly 2, and the supporting seat 18 and the lower part of the kettle body 1 form a slow flow chamber 19, wherein the air inlet pipe 13 is connected to the slow flow chamber 19. Since the supporting seat 18 is annular, the air inlet end 221 of the bottom storage mechanism 22 of the basket assembly 2 is connected to the slow flow chamber 19, and the supporting seat 18 is also provided with an air supply channel 100 connecting the slow flow chamber 19 with the first chamber 11. Specifically, those skilled in the art can adjust the size of the opening of the air supply channel 100, so as to adjust the flow rate of the supercritical extraction fluid from the slow flow chamber 19 into the first chamber 11, so that the supercritical extraction fluid can enter the air inlet end 221 of the storage mechanism 22 at the same flow rate.

[0040] It is worth mentioning here that Figure 3 As shown, although the position of the mouth of the air inlet pipe 13 in the drawing is aligned with the air inlet end 221 of the bottom material storage mechanism 22 of the basket assembly 2, it does not mean that the supercritical extraction fluid flowing out of the air inlet pipe 13 will directly impact the air inlet end 221 of the bottom material storage mechanism 22. The mouth of the air inlet pipe 13 can be tilted at an angle to the air inlet end 221 of the bottom material storage mechanism 22, or an impact plate to prevent impact can be added to the slow flow chamber 19 to solve the above problem. Since the above solution is easy for people in this field to think of, the applicant has not provided a drawing of the inclined setting of the air inlet pipe 13 and a drawing structure of the installation position of the impact plate.

[0041] In order to enable the diversion mechanism 23 to complete the diversion of the supercritical extraction fluid, in this embodiment, Figure 8 As shown, the diversion mechanism 23 includes a diversion tube 230, wherein the diversion tube 230 is distributed along the axial direction of the kettle body 1, the first diversion channel 231 includes a first air outlet 2311 and a first air inlet 2312, and the second diversion channel 232 includes a second air outlet 2321 and a second air inlet 2322, wherein the first air outlet 2311 and the second air inlet 2322 are distributed along the axial direction of the diversion tube 230; since the supercritical extraction fluid in this embodiment flows from bottom to top, the first air outlet 2311 is located above the second air inlet 2322, and the first air inlet 2312 and the second air outlet 2321 are located on the side wall of the diversion tube 230. Specifically, the first diversion channel 231 and the second diversion channel 232 are separated by a partition plate 233.

[0042] like Figure 9As shown, the storage mechanism 22 includes a storage barrel 220, wherein the storage barrel 220 is a cylindrical structure, the air inlet end 221 of the storage mechanism 22 is located at the bottom of the storage barrel 220, the air outlet end 222 of the storage mechanism 22 is located at the top of the storage barrel 220, the first air outlet 2311 of the diverter barrel 230 is connected to the air inlet end 221 of the storage barrel 220 above it, and the second air inlet 2322 of the diverter barrel 230 is connected to the air outlet end 222 of the storage barrel 220 below it.

[0043] In order to be able to package the raw materials in the storage barrel 220, in this embodiment, as shown in FIG. Figure 10 and Figure 12 As shown, the air inlet end 221 and the air outlet end 222 of the storage barrel 220 are respectively installed with a first material blocking member 223 and a second material blocking member 224, wherein the first material blocking member 223 and the second material blocking member 224 are hinged on the storage barrel 220, and the air inlet end 221 and the air outlet end 222 can be opened or closed, and the raw materials can be placed into the storage barrel 220 or the raw materials extracted from the storage barrel 220 can be released.

[0044] It is worth noting that both the first blocking member 223 and the second blocking member 224 have a ventilation effect, so that the supercritical extraction fluid can smoothly pass through the storage barrel 220.

[0045] The structures of the first blocking member 223 and the second blocking member 224 are as follows: Figure 11 and Figure 12 As shown, the bottom and top walls of the storage barrel 220 are both provided with an inwardly recessed sedimentation trough 2201, and the side walls of the sedimentation trough 2201 are provided with a mounting groove 2202. The first material blocking member 223 and the second material blocking member 224 both include a material blocking plate 225 and a rotating seat 226 provided on the peripheral wall of the material blocking plate 225, wherein the rotating seat 226 is inserted into the mounting groove 2202 and the rotating seat 226 is rotatably connected to the inner wall of the mounting groove 2202. When the material blocking plate 225 is located inside the sedimentation trough 2201, it can encapsulate the raw material in the inner cavity of the storage barrel 220. In order to realize the flow of the supercritical extraction fluid, in this embodiment, the material blocking plate 225 is further provided with a plurality of ventilation holes 2251 provided therethrough, wherein the supercritical extraction fluid can smoothly pass through the storage barrel 220 through the ventilation holes 2251 to complete the extraction of the raw material.

[0046] Since the extraction kettle of the present application may need to extract raw materials of different particle sizes, the aperture of the air-permeable hole 2251 on the material blocking plate 225 cannot be adjusted. When the particle size of the raw material is small, the raw material is easy to flow out from the inner cavity of the storage barrel 220 through the air-permeable hole 2251, thereby causing the loss of the raw material. Therefore, in this embodiment, Figure 13As shown, a barrier net 3 is further provided on the side of the material blocking plate 225 facing the inner cavity of the storage barrel 220, wherein the barrier net 3 is detachably connected to the material blocking plate 225, which can facilitate the removal and replacement of the barrier net 3. When extracting raw materials of different particle sizes, an appropriate barrier net 3 can be selected to block the raw materials and prevent the raw materials from being lost from the storage barrel 220.

[0047] In order to achieve the installation of the barrier net 3, an embedding groove 2252 is provided on the side of the material blocking plate 225 close to the material storage barrel 220, and also includes an embedding ring 31. The barrier net 3 is attached to the material blocking plate 225 to block the air permeable hole 2251, and then the embedding ring 31 is used to press the barrier net 3 into the embedding groove 2252, thereby achieving the fixation of the barrier net 3.

[0048] Under normal circumstances, after the supercritical extraction fluid flows into the inner cavity of the storage barrel 220 at a high speed, the raw materials in the storage barrel 220 are easily penetrated due to the uneven distribution of the extraction fluid, thereby reducing the contact between the supercritical extraction fluid and the raw materials, thereby affecting the extraction effect of the raw materials. This phenomenon mainly occurs at the air inlet end 221 of the storage barrel 220. Therefore, in this embodiment, Figure 12 As shown, further improvements are made to the second material blocking member 224, wherein the second material blocking member 224 also includes a spoiler 229, wherein the spoiler 229 is installed on the material blocking plate 225 and is located on the side away from the storage barrel 220, and a spoiler cavity 2291 is formed between the spoiler 229 and the material blocking plate 225, and the spoiler 229 is also provided with a plurality of spoiler holes 2290 connected to the spoiler cavity 2291.

[0049] Through the above-mentioned arrangement, the supercritical extraction fluid in the first chamber 11 flows to the side of the air inlet end 221 of the storage barrel 220 through the first diversion channel 231. At this time, the supercritical extraction fluid touches the spoiler plate 229, and the extraction fluid enters the spoiler cavity 2291 through a number of spoiler holes 2290. At this time, the supercritical extraction fluid is evenly distributed in the spoiler cavity 2291. Finally, the supercritical extraction fluid in the spoiler cavity 2291 enters the inner cavity of the storage barrel 220 through the air permeable hole 2251 of the material blocking plate 225 on the second material blocking member 224, thereby reducing the risk of the raw material in the storage barrel 220 being punctured.

[0050] In this embodiment, if Figure 12 and Figure 13As shown, the first material blocking member 223 and the second material blocking member 224 both include an extension plate 227, a locking bolt 228 and a threaded hole 2203, wherein the threaded hole 2203 is arranged on the storage barrel 220, and the extension plate 227 is fixedly installed on the peripheral wall of the material blocking plate 225, and the locking bolt 228 is threadedly connected to the extension plate 227. When the material blocking plate 225 blocks the air inlet end 221 or the air outlet end 222, the locking bolt 228 is aligned with the threaded hole 2203. By rotating the locking bolt 228, the locking bolt 228 can be screwed into the threaded hole 2203, thereby realizing the fixation of the first material blocking member 223 and the second material blocking member 224.

[0051] It is worth noting here that the outer diameters of the first blocking member 223 and the second blocking member 224 are smaller than the inner diameters of the first diversion channel 231 and the second diversion channel 232. When the first blocking member 223 is opened, the first blocking member 223 can be flipped into the second diversion channel 232. When the second blocking member 224 is opened, the second blocking member 224 can be flipped into the first diversion channel 231, so that the raw materials can be loaded into the storage barrel 220 or the extracted raw materials can be discharged from the storage barrel 220.

[0052] The conventional material basket assembly 2 fixes multiple sections of the material storage barrel 220 with bolts, and encapsulates the raw materials in the inner cavity of each material storage barrel 220. In this case, each section of the material storage barrel 220 needs to be dismantled before the raw materials can be filled and discharged. In the present application, the material basket assembly 2 is directly lifted out of the kettle body 1. Without the need to dismantle the material storage barrel 220, the air outlet end 222 or the air inlet end 221 can be opened through the first material blocking member 223 and the second material blocking member 224, thereby facilitating the filling or discharge of raw materials and improving the raw material processing efficiency.

[0053] Among them, such as Figure 10 As shown, the first blocking member 223 and the second blocking member 224 are used to encapsulate the raw materials. At this time, the supercritical extraction fluid can flow to the corresponding storage barrel 220 through the diversion mechanism 23, thereby achieving simultaneous extraction of the raw materials inside the multiple storage barrels 220 and improving the raw material extraction efficiency.

[0054] like Figure 11 As shown, at this time, the first blocking member 223 opens the air outlet end 222 of the storage barrel 220 and flips it into the second diversion channel 232. At this time, the raw materials can be filled into the storage barrel 220 through the air outlet end 222; when the second blocking member 224 opens the air inlet end 221 at the bottom of the storage barrel 220, the second blocking member 224 flips into the first diversion channel 231, and the raw materials can be discharged from the air inlet end 221 after extraction from the storage barrel 220.
