[0050] refer to Figures 1 to 6 This disclosure provides a solvent extraction apparatus, including a container 1, a partition 3, a solvent circulation device 4, and a stirring device 6. The container 1 is configured to hold materials and the solvent required to extract a target component from the materials. The partition 3 is configured to divide the internal space of the container 1 into a first region and a second region, the partition 3 being able to prevent materials from entering the second region from the first region and allowing solvent to flow between the first and second regions. The solvent circulation device 4 is configured to circulate the solvent between the first and second regions. The stirring device 6 is configured to stir the materials and solvent in the first region.

[0051] In the solvent extraction apparatus provided in the embodiments of this disclosure, the material can be food or medicinal material, or other material from which effective components can be extracted using a solvent. The shape of the material can be block, granular, flake, etc., and the solvent can be a liquid capable of dissolving the target component. In some embodiments, the solvent extraction apparatus can be used as an extraction apparatus for effective components of bird's nest, the material being bird's nest raw material, and the target component being sialic acid, protein, etc.

[0052] Optionally, refer to Figures 1 to 4 Container 1 is cylindrical. (Reference) Figure 2 and Figure 5 In the solvent extraction equipment, the first region is the area inside container 1 located above the partition 3, and the second region is the area inside container 1 located below the partition 3. Thus, the first region can serve as a storage area for materials and a region where the solvent acts on the materials, while the second region can serve as a storage area for the solvent.

[0053] In the solvent extraction device provided in the embodiments of this disclosure, the separator 3 divides the internal space of the container 1 into different regions. The solvent can penetrate into the first region through the separator 3, and the separator 3 can prevent the material from sinking from the first region to the second region, thereby reducing the risk of the material sinking and blocking the solvent circulation channel.

[0054] Under the action of the solvent circulation device 4, the solvent forms a closed-loop circulation and continuous flow of "second region - solvent circulation device 4 - first region - separator 3 - second region", which can reduce the risk of concentration saturation of the target component in the solvent in local areas. Furthermore, under the action of the stirring device 6, the solvent can fully contact the material, breaking the concentration gradient of the solvent on the material surface. Therefore, it can be seen that the solvent extraction equipment provided by the embodiments of this disclosure is beneficial to improving the dissolution efficiency of the target component.

[0055] refer to Figures 2 to 5 In some embodiments of the solvent extraction apparatus, the separator 3 includes a mesh 301 and a mounting frame 302, the mesh 301 being detachably connected to the container 1 via the mounting frame 302.

[0056] In this embodiment, when the partition 301 is installed inside the container 1, the partition 3 can block the material from entering the second region from the first region and allow the solvent to enter the second region from the first region. When it is necessary to replace, maintain and clean the partition 301, the partition 301 can be removed from the container 1.

[0057] refer to Figures 2 to 4 In some embodiments of the solvent extraction device, a bracket 101 is provided on the inner wall of the container 1. The bracket 101 supports the mounting frame 302 and is detachably connected to the mounting frame 302 by a plurality of pin holes distributed circumferentially along the container 1.

[0058] Optionally, refer to Figures 2 to 4 The bracket 101 is annular, and the mounting bracket 302 is annular. Optionally, refer to... Figures 2 to 4 The bracket 101 is provided with a first connecting structure 102, and the mounting bracket 302 is provided with a second connecting structure 303. The first connecting structure 102 and the second connecting structure 303 form a pin hole connection structure. The first connecting structure 102 is a pin, and the second connecting structure 303 is a hole. The axial direction of the pin hole connection structure is the arrangement direction of the first region and the second region, that is, the height direction of the container 1.

[0059] In this embodiment, the multiple pin hole connection structure distributed along the circumference of the container 1 can accurately and firmly connect the bracket 101 and the mounting bracket 302, so that the partition 3 is subjected to uniform force, reducing the risk of the partition 3 being displaced by the impact of solvent flow, further improving the stability of the solvent extraction environment, and improving the problem of fluctuation in the dissolution efficiency of the target component caused by structural displacement.

[0060] In some embodiments of the solvent extraction apparatus, the separator 3 includes a plurality of replaceable meshes 301, the different meshes 301 having different pore sizes.

[0061] In this embodiment, multiple replaceable screens 301 can be adapted to different target component extraction needs, which helps to improve the versatility of the equipment and facilitates the maintenance and cleaning of the screens 301.

[0062] In some embodiments of the solvent extraction apparatus, the stirring device 6 includes a rotating shaft 601 and a stirring section 602. The stirring section 602 is disposed on the outer periphery of the rotating shaft 601 to rotate with the rotating shaft.

[0063] Optionally, refer to Figure 2 , Figure 3 The stirring device 6 includes a drive motor 603, which is driven by a rotating shaft 601 to drive the rotating shaft 601 to rotate.

[0064] Optionally, refer to Figure 2 , Figure 3 The stirring device 6 includes multiple rotating shafts 601, each rotating shaft 601 is provided with multiple sets of stirring parts 602, the multiple sets of stirring parts 602 are spaced apart along the axial direction of the rotating shaft 601, and each set of stirring parts 602 includes multiple stirring parts 602 evenly distributed along the axial direction of the rotating shaft 601.

[0065] In some embodiments of the solvent extraction apparatus, the stirring section 602 is made of an elastic material.

[0066] In this embodiment, the stirring part 602 made of elastic material can reduce the risk of mechanical damage to materials such as bird's nest raw materials during the stirring process, thereby reducing the risk of material breakage generating impurities and mixing into the extract, affecting the purity.

[0067] refer to Figure 2 , Figure 3 , Figure 5 In some embodiments of the solvent extraction apparatus, the stirring section 602 is arc-shaped.

[0068] Optionally, the stirring part 602 is arc-shaped and made of an elastic material.

[0069] Optionally, refer to Figure 2 , Figure 3 , Figure 5 The stirring section 602 extends along an arc and has a circular cross-section. One end of the arc-shaped stirring section 602 is connected to the circumferential outer surface of the rotating shaft 601, and the other end is a free end. Optionally, the outer circumferential surface of the stirring section 602 is a smooth transition surface.

[0070] In this embodiment, when the stirring device 6 is working, the arc-shaped stirring part 602 has a smooth arc-shaped stirring surface, which can gently turn the material in the first area, and is less likely to cause mechanical damage to materials such as bird's nest raw materials during the stirring process.

[0071] refer to Figures 1 to 3 In some embodiments of the solvent extraction apparatus, the solvent circulation device 4 includes a circulation pipeline 401 and a pump 402, the pump 402 being configured to transport solvent from a second region to a first region through the circulation pipeline 401; the solvent extraction apparatus includes a nozzle 5, the nozzle 5 being disposed inside the container 1 and connected to the outlet of the circulation pipeline 401, and being configured to spray solvent into the first region.

[0072] Optionally, refer to Figure 1 and Figure 3 Pump 402 is fixedly installed on the outer wall of container 1. Optionally, a seal 403 is provided at the connection between the outlet of circulation pipeline 401 and nozzle 5 to prevent solvent from leaking out from the connection between circulation pipeline 401 and nozzle 5.

[0073] refer to Figure 6 In some embodiments of the solvent extraction apparatus, the nozzle 5 includes a housing 501 and a blade 502. The housing 501 has a solvent inlet 503 and a solvent outlet 504, and the housing 501 is rotatably connected to the outlet of the circulation pipe 401 about the axis of the circulation pipe 401. The blade 502 is disposed inside the housing 501 and located between the solvent inlet 503 and the solvent outlet 504, and the housing 501 is rotatable with the blade 502.

[0074] Optionally, the blade 502 is connected to the inner wall of the housing 501 through its circumferential edge, and there are gaps between the multiple blades of the blade 502.

[0075] In this embodiment, under the action of pump 402, solvent enters the interior of housing 501 through circulation pipe 401 and solvent inlet 503, and acts on impeller 502. Under the impact of flowing solvent, impeller 502 can drive housing 501 to rotate around the axis of impeller 502 relative to the outlet of circulation pipe 401, so that solvent forms a rotating liquid flow, which is beneficial to expand the contact range between solvent and material and enhance the dynamic effect of solvent.

[0076] refer to Figure 6 In some embodiments of the solvent extraction apparatus, the solvent outlet 504 obliquely penetrates the shell wall of the housing 501.

[0077] Optionally, multiple solvent outlets 504 are disposed on the end face of the housing 501 away from the circulation pipeline 401 and on the side face of the housing 501. Optionally, the solvent outlets 504 on the end face of the housing 501 away from the circulation pipeline 401 are evenly distributed, and the solvent outlets 504 on the side face of the housing 501 are evenly distributed.

[0078] In this embodiment, the solvent is sprayed out at an angle through the solvent outlet 504, which can reduce solvent splashing. This not only reduces the risk of the material being separated from the raw material area by the splashed solvent, but also reduces the risk of solvent splashing onto the inner wall of container 1 and causing solvent loss. This indirectly assists in "solvent lock-in" and helps maintain the stability of the target component concentration.

[0079] In some embodiments of the solvent extraction apparatus, the wall of container 1 is provided with a jacket 103, which is configured to be filled with a heating medium required for heating the solvent.

[0080] In some embodiments of the solvent extraction apparatus, the solvent extraction apparatus includes a turbulence section 104 disposed inside the container 1 and configured to cause the solvent in the area to form a vortex. A heating element is disposed inside the turbulence section 104.

[0081] Optionally, the heating medium filled in the interlayer 103 is heat transfer oil.

[0082] In this embodiment, the turbulence section 104 can not only guide the solvent to form a vortex, but the heating element inside it can also heat the solvent at the location. The heating medium filled in the interlayer 103 can play an overall heat preservation role for the solvent, thereby achieving a graded temperature control effect of "core heating and heat preservation compensation".

[0083] In some embodiments of the solvent extraction apparatus, the flow-dispersing section 104 includes a flow-dispersing plate, the surface of which is a spiral surface.

[0084] In this embodiment, the baffle is a spiral plate. Along the arrangement direction of the first region and the second region, the baffle 104 divides the second region into a spiral flow channel. This not only guides the solvent to flow spirally within it, providing a better turbulence effect and improving the temperature uniformity of the target component in the solvent, but also allows the solvent to fully contact the baffle 104 and be uniformly heated during the flow of the spiral flow channel, thereby improving the temperature uniformity of the solvent.

[0085] refer to Figures 2 to 5 In some embodiments of the solvent extraction apparatus, a temperature measuring device 2 is included. The temperature measuring device 2 is configured to detect the temperature of the solvent at both ends of the second region along the arrangement direction of the first and second regions, so as to adjust the heating power of the heat source of the heating medium and the heating power of the heating element, respectively.

[0086] Optionally, refer to Figure 3 and Figure 4 The temperature measuring device 2 includes a first temperature sensor 21 and a second temperature sensor 22. Along the arrangement direction of the first and second regions, the first temperature sensor 21 is located on the side of the second region adjacent to the first region, and the second temperature sensor 22 is located on the side of the second region away from the first region. In the operating state of the solvent extraction device, the first region is located at the upper part of the container 1, and the second region is located at the lower part of the container 1. The first temperature sensor 21 and the second temperature sensor 22 can respectively detect the temperature of the solvent in the middle and bottom of the container 1.

[0087] Optionally, the temperature measuring device 2 includes a plurality of first temperature sensors 21 and a plurality of second temperature sensors 22. The plurality of first temperature sensors 21 are evenly distributed along the circumference of the container 1 on the bracket 101, and the plurality of second temperature sensors 22 are evenly distributed along the circumference of the container 1 on the inner wall of the bottom of the container 1.

[0088] The heating source of the heating medium can be, for example, an electric heating source, and the heating element can be, for example, an electric heating tube. Optionally, the solvent extraction equipment includes a control device, which is signal-connected to the heating source and the heating element of the heating medium, and is configured to adjust the heating power of the heating source and the heating power of the heating element.

[0089] In this embodiment, when the solvent extraction equipment is in use, the temperature measuring device 2 can detect the temperature of the solvent in the upper and lower parts of the second region, that is, the temperature of the solvent in the middle and bottom parts of the container 1, respectively, providing multi-dimensional temperature data. This makes it easy to know the temperature of the solvent in different regions, and adjust the heating power of the heating source of the heating medium and the heating power of the heating element accordingly. This helps to improve the control accuracy of the solvent temperature and better adapt to the dissolution temperature requirements of different components of bird's nest.

[0090] refer to Figures 2 to 5In some embodiments of the solvent extraction apparatus, an extraction tube 105 is included, which is disposed on the wall of the container 1 in the second region and is in fluid communication with the second region, so as to extract a solvent containing the target component from the second region.

[0091] In this embodiment, the target component extract can be obtained through extraction tube 105.

[0092] refer to Figures 2 to 5 In some embodiments of the solvent extraction apparatus, along the arrangement direction of the first and second regions, the outlet end of the extraction tube 105 is closer to the first region than the end connected to the second region.

[0093] Optionally, refer to Figures 2 to 5 The extraction tube 105 is connected to the bottom of the container 1 and is set at an angle relative to the container 1.

[0094] In this embodiment, the outlet end of the extraction tube 105 and the end connected to the second region are kept at a certain distance. When the solvent extraction device is in use, the second region is located at the bottom of the container 1, and the outlet of the extraction tube 105 faces the top of the container 1. Even if there are material impurities deposited at the bottom of the container 1, they are not easy to be extracted, which can reduce the risk of impurities being mixed into the extract.

[0095] In some embodiments of the solvent extraction apparatus, a filter screen is included, which is installed at the outlet end of the extraction tube 105.

[0096] Optionally, the filter screen can be detachably installed at the outlet of the extraction tube 105. For example, the edge of the filter screen can be connected to the outlet of the extraction tube 105 by a snap fastener for quick removal and cleaning of the filter screen.

[0097] In this embodiment, by setting a filter screen at the outlet end of the extraction tube 105, when extracting solvent containing the target component, it can intercept and filter material impurities in the solvent, which helps to reduce the risk of impurities mixing into the extract and enables the solvent extraction equipment to better adapt to application scenarios where the extract has purity requirements.

[0098] In some embodiments, the control device described above may be implemented as a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any suitable combination thereof for performing the functions described herein.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this disclosure.
