Description

Technical Field

[0001] This invention relates to the field of bee product component extraction technology, specifically a continuous countercurrent extraction device for extracting anti-tumor components from bee products. Background Technology

[0002] Bee products, such as propolis and royal jelly, are a natural treasure trove of bioactive substances, including many components with potential anti-tumor activity, such as flavonoids, terpenes, phenolic acids, and specific fatty acids. The efficient and high-purity extraction of these high-value components is a crucial step in developing them into functional food or pharmaceutical raw materials. Liquid-liquid extraction technology, especially continuous countercurrent extraction technology, is considered one of the ideal processes for achieving this goal due to its high extraction efficiency, low solvent consumption, and ease of large-scale continuous production.

[0003] However, several unique technical challenges exist when using continuous countercurrent extraction equipment to process bee product extracts, which restrict the improvement of extraction efficiency and product quality: Many antitumor active ingredients in bee products are extremely sensitive to temperature. Inappropriate heating can lead to their degradation and inactivation, thereby reducing yield and product efficacy. Traditional extraction equipment typically uses only a jacket for overall heating or cooling, resulting in a crude temperature control method that makes it difficult to create a uniform and precise temperature field inside the equipment. Especially in the core mixing area, the conversion of mechanical energy into heat energy and frictional heat generation can easily create localized hot spots, causing irreversible damage to heat-sensitive components. Summary of the Invention

[0010] Preferably, a number of fixing rings are fixedly installed inside the extraction tower.

[0011] Preferably, the adjustment mechanism includes a side rail, which is fixed to one end of two fixed boxes. A worm gear is fixedly sleeved on the outer side of each rotating shaft. A worm is rotatably connected to the inside of each fixed box via bearings. Each worm engages with a worm gear.

[0014] This invention provides a continuous countercurrent extraction device for extracting antitumor components from bee products, which has the following beneficial effects: 1. Precise temperature control within the extraction tower was achieved, optimizing extraction efficiency and product stability. By setting up three independent temperature control jackets (upper, middle, and lower) and supplementing them with hot water circulation pipelines, different areas within the extraction tower can be heated in sections. Simultaneously, the drive disc is designed with a hollow structure and connected to the rotating shaft and external rotary joint, forming an internal channel for heating or cooling media. This combined internal and external temperature control system can precisely control the temperature within the extraction tower, including the static space and rotating stirring components, providing a stable and optimal extraction temperature environment for heat-sensitive antitumor components in bee products. This is beneficial for mass transfer efficiency and also protects the activity of the components.

[0015] 2. The grid mechanism is driven by a specialized adjustment mechanism, allowing manual adjustment of the grid's opening ratio by rotating the rotating column. Specifically, the adjustment mechanism, through a worm gear and rack and pinion drive, ultimately drives a slotted rotating ring to rotate relative to a fixed positioning ring, causing the slots to misalign and altering the effective flow orifice size. This allows operators to adjust the flow and shear conditions within the tower in real time, based on the physical properties of different bee product raw materials such as viscosity, emulsifiability, or solvent system, without shutting down the system. This achieves an optimal balance between enhancing dispersion with small openings and promoting aggregation with large openings, to meet the requirements of different batches of raw materials and processing.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1 Please see Figures 1 to 6 The present invention provides a technical solution: a continuous countercurrent extraction device for extracting anti-tumor components from bee products, including an extraction tower 1, a drive mechanism 3 installed inside the extraction tower 1, a grid mechanism 5 installed inside the extraction tower 1 and above and below the drive mechanism 3, a temperature control device 2 fixedly installed on the outside of the extraction tower 1, and an adjustment mechanism 4 for driving the grid mechanism 5 to work fixedly installed on the sides of the two grid mechanisms 5. The grid mechanism 5 includes mounting rings 501. Two mounting rings 501 are fixed to the inner walls of the upper and lower chambers of the extraction tower 1, respectively. A top pipe 502 is fixedly installed at the top of each mounting ring 501, and a bottom pipe 503 is fixedly installed at the bottom of each mounting ring 501. A positioning ring 505 is fixedly installed inside the mounting ring 501. A rotating ring 504 is slidably sleeved below the positioning ring 505. An annular cavity is opened inside the mounting ring 501 and outside the rotating ring 504. A toothed ring 507 is placed inside the annular cavity. The inner side of the toothed ring 507 is fixedly connected to the outer side of the rotating ring 504. Through grooves 506 are opened on the surfaces of both the positioning ring 505 and the rotating ring 504.

[0020] Furthermore, a fixed box 508 is fixedly installed on the outside of the extraction tower 1 and on the left side of the mounting ring 501. The fixed box 508 is rotatably connected to the rotating shaft 510 through bearings. The rotating shaft 510 is fixedly fitted with a transmission gear 512 on the outside. One end of the transmission gear 512 extends into the annular cavity and cooperates with the gear ring 507.

[0021] Those skilled in the art can effectively transmit the power of the external adjustment mechanism 4 to the gear ring 507 and rotating ring 504 sealed inside the equipment by setting an external fixed box 508 and a transmission gear 512. This external transmission design avoids the need to create a complex dynamic sealing structure for the transmission components on the main body of the extraction tower 1, thereby ensuring the sealing reliability of the main body of the equipment while realizing the dynamic adjustment function of the internal components, reducing the risk of leakage, and simplifying manufacturing and maintenance.

[0022] Furthermore, a rotating shaft 303 is rotatably connected inside the extraction tower 1 via bearings. A drive seat 301 is fixedly installed on the top of the extraction tower 1. Several rotating disks 306 are fixedly sleeved on the outer side of the rotating shaft 303. The rotating disks 306 have a hollow structure and are connected to the interior of the rotating shaft 303. The top end of the rotating shaft 303 extends above the drive seat 301 and is connected to the bottom end of the first rotary joint 307 installed above the drive seat 301. A second rotary joint 308 is installed at the bottom of the extraction tower 1. The top end of the rotating shaft 303 is connected to the bottom end of the first rotary joint 307, and the bottom end of the rotating shaft 303 is connected to the top end of the second rotary joint 308.

[0023] Those skilled in the art will design the turntable 306 and the rotating shaft 303 as hollow structures that are interconnected, and connect them to an external circulation pipeline through the first rotary joint 307 and the second rotary joint 308, forming a rotating internal temperature control channel. This allows the heating or cooling medium to flow directly through the high-speed rotating stirring core area, achieving direct and efficient temperature control of the area where the two-phase mixing is most intense and mass transfer is most crucial. This is essential for protecting the heat-sensitive antitumor active ingredients in bee products and preventing their inactivation under strong shear and frictional heat generation, while also enabling precise control of extraction kinetics by optimizing local temperature.

[0024] Furthermore, the temperature control device 2 includes an upper temperature control jacket 201, a middle temperature control jacket 202, and a lower temperature control jacket 203. The upper temperature control jacket 201, the middle temperature control jacket 202, and the lower temperature control jacket 203 are installed on the outside of the extraction tower 1 in a top-to-bottom order. Hot water circulation inlet pipes 204 are fixedly installed on the right side of the upper temperature control jacket 201, the middle temperature control jacket 202, and the lower temperature control jacket 203, and hot water circulation outlet pipes 205 are fixedly installed on the left side of the upper temperature control jacket 201, the middle temperature control jacket 202, and the lower temperature control jacket 203.

[0025] Those skilled in the art will design the temperature control device 2 as a zoned independent temperature control system consisting of an upper temperature control jacket 201, a middle temperature control jacket 202, and a lower temperature control jacket 203. Each jacket has an independent hot water circulation inlet pipe 204 and a hot water circulation outlet pipe 205. This zoned design allows for differentiated and precise temperature control of different functional sections of the extraction tower 1, such as the upper light liquid clarification section, the middle mixed extraction section, and the lower heavy liquid clarification section. This creates an optimal, customizable temperature gradient for the entire countercurrent extraction path, which helps maintain the stability of the two-phase properties, control interfacial tension, optimize phase separation, and thus comprehensively improve separation efficiency.

[0026] Furthermore, a motor 302 is fixedly installed on the top of the drive base 301, and the output end of the motor 302 extends into the interior of the drive base 301. The outer side of the output end of the motor 302 and the outer side of the rotating shaft 303 are both fixedly fitted with a first drive gear 304 that meshes with each other.

[0027] Those skilled in the art will understand that the first drive gear 304, connected to its output end and rotating shaft 303, is driven by the motor 302 for meshing transmission. This structure is simple and reliable, and the power transmission is efficient and direct. It ensures that the turntable 306 can obtain a stable and adjustable rotational speed, providing controllable shear force for the liquid-liquid two-phase system, which is fundamental to enhancing dispersion and increasing the mass transfer area.

[0028] Furthermore, several fixing rings 305 are fixedly installed inside the extraction tower 1.

[0029] Those skilled in the art will know that several retaining rings 305 are fixedly installed inside the extraction column 1. These retaining rings 305 can divide the space inside the column into multiple series-connected mixing-clarification chambers, effectively limiting axial backmixing of the two-phase liquids, making the flow closer to the ideal plug flow, thereby improving the theoretical efficiency. At the same time, they help to disperse the liquid flow, promote droplet coalescence and two-phase stratification, and are key structures to ensure the countercurrent extraction effect.

[0030] Furthermore, the adjustment mechanism 4 includes a side rail 401, which is fixed to one end of two fixed boxes 508. Worm gears 511 are fixedly sleeved on the outer side of the rotating shaft 510. Worms 509 are rotatably connected to the inside of each fixed box 508 via bearings. Each worm 509 engages with a worm gear 511. One end of each worm 509 extends into the side rail 401 and is fixedly sleeved with a second drive gear 513. A threaded rod 402 is rotatably connected to the inside of the side rail 401 via bearings. A slider 403 is threadedly connected to the outer side of the threaded rod 402. A rack 405 is fixedly connected to the surface of the slider 403, and the rack 405 engages with the second drive gear 513. A rotating column 406 is rotatably connected to the side of the side rail 401 via bearings. A meshing bevel gear 407 is fixedly sleeved on the outer side of both the rotating column 406 and one end of the threaded rod 402. One end of the rotating column 406 extends to the outer side of the side rail 401.

[0031] Those skilled in the art can convert the motion of the rotating column 406 into synchronous adjustment of the two grid mechanisms 5 using a linkage mechanism integrating a worm gear 511, a worm 509, a threaded rod 402, a slider 403, and a rack 405. The worm gear 511 and 509 transmission has a self-locking function, preventing changes in the set position of the grid mechanism 5 due to fluid impact after adjustment, thus ensuring the stability of the opening ratio during operation. The entire mechanism is compact in design and precise in transmission, achieving synchronous and reliable control from a single operating point to two grids.

[0032] Furthermore, a guide rod 404 is fixedly installed inside the side rail 401, and the inside of the slider 403 is slidably connected to the outside of the guide rod 404.

[0033] Those skilled in the art will understand that the guide rod 404 ensures that the slider 403 moves smoothly along a straight line without wobbling.

[0034] Furthermore, a clear liquid inlet 104 is installed on the right side of the extraction tower 1, and a heavy liquid inlet 103 is fixedly installed on the right side of the extraction tower 1 and above the clear liquid inlet 104. One end of the clear liquid inlet 104, the heavy liquid inlet 103 and the hot water circulation discharge pipe 205 all extend to the outside of the side rail 401. A clear liquid outlet 101 is fixedly installed on the top of the extraction tower 1, and a heavy liquid outlet 102 is fixedly installed on the bottom of the extraction tower 1.

[0035] Those skilled in the art can ensure that the two phases can achieve stable and sufficient countercurrent contact. Simultaneously, leading out the hot water circulation discharge pipe 205 together with the material inlet makes the external pipeline layout of the equipment neat and facilitates connection to external piping systems and insulation construction, thereby improving the overall integrity of the equipment and the convenience of engineering installation.

[0036] Example 2 Please see Figures 1 to 3The present invention provides a technical solution: the surface of the side rail 401 is inlaid with a scale 408 that cooperates with the slider 403.

[0037] The scale 408, in conjunction with the slider 403, enables the visualization and quantification of the aperture ratio adjustment of the grid mechanism 5. Operators can accurately read and reproduce the aperture ratio state corresponding to the position of slider 403.

[0038] In summary, this continuous countercurrent extraction equipment for extracting anti-tumor components from bee products, when used, Material introduction and countercurrent contact: Bee product extracts, typically an aqueous phase or a denser liquid phase containing the target anti-tumor components, enter the extraction tower 1 through the heavy liquid inlet 103 on the side of the equipment. Due to its higher density, it tends to flow downwards within the tower.

[0039] The extractant is typically an organic solvent used to extract the target component. It has a lower density and enters the extraction column 1 through the clear liquid inlet 104, located above the heavy liquid inlet 103. Due to its lower density, it tends to flow upwards within the column.

[0040] The two liquids flowed in opposite directions within the tower.

[0041] Mechanical stirring and mass transfer enhancement: The motor 302 on the top of the device starts, and its output drives the first drive gear 304 to rotate.

[0042] The first drive gear 304 meshes with the gear on the rotating shaft 303, thereby driving the rotating shaft 303 and the multiple turntables 306 fixedly mounted on it to rotate together.

[0043] The rotating disk 306 generates shear force within the column, breaking up the continuous heavy liquid and dispersing the other phase, a lighter liquid, into tiny droplets. This significantly increases the contact area between the two phases, enhancing the mass transfer process and allowing the antitumor components in the bee product extract to dissolve and distribute more quickly and fully into the extract.

[0044] Temperature control: During this process, the temperature control device 2 on the outside of the equipment heats the tower wall through hot water circulation, providing and maintaining the optimal temperature for the extraction process.

[0045] Heat source input: Externally heated hot water or other heat medium is injected into three independent temperature control jackets through hot water circulation inlet pipe 204, namely upper temperature control jacket 201, middle temperature control jacket 202 and lower temperature control jacket 203.

[0046] Partitioned hot-swapping: Hot water flows within its respective jacket cavity, exchanging heat with the metal walls of extraction tower 1. Heat is then conducted through the tower walls to the material in the corresponding areas within the tower.

[0047] Upper temperature control jacket 201: mainly used to heat or keep warm the upper part of the tower body, which is usually the accumulation and outlet area of ​​light liquid / extraction phase.

[0048] Medium temperature control jacket 202: Precisely controls the temperature of the main mixing and extraction reaction zone in the middle of the tower, which is the core area where mass transfer occurs.

[0049] Lower temperature control jacket 203: Heating or insulation of the lower part of the tower body, which is usually the accumulation and outlet area of ​​heavy liquid / raffinate phase.

[0050] Heat medium recirculation and recycling: After the heat exchange is completed, the hot water or cooled medium, which has cooled down, flows out from the hot water circulation discharge pipe 205 on the left side of each jacket.

[0051] Closed loop: The medium flowing out of the hot water circulation discharge pipe 205 is guided to external supporting heating or cooling devices such as boilers, heat exchangers, temperature control units, etc. (not shown in the figure, belonging to the external system) for reheating or cooling to the set temperature.

[0052] Continuous loop: After being conditioned by external equipment, the medium is pumped again and injected into each temperature-controlled jacket via hot water circulation inlet pipe 204, starting a new cycle. This process repeats continuously, forming a closed-loop heat exchange circulation system, thereby continuously and stably providing the required temperature environment for the extraction process.

[0053] Meanwhile, the turntable 306 is designed as a hollow structure, communicating internally with the rotating shaft 303 to form another independent temperature control channel. The heating medium enters the rotating shaft 303 and the turntable 306 through the first rotary joint 307, and then flows out from the second rotary joint 308, forming a circulation. This enables direct temperature control of the stirring core area, ensuring protection of the heat-sensitive active ingredients of bee products and optimizing extraction kinetics.

[0054] Flow regulation and separation: The fixed ring 305 and adjustable grid mechanism 5 installed inside the tower play a role in regulating the flow field, suppressing axial backmixing, and promoting droplet coalescence and phase separation. By adjusting the mechanism 4 to change the opening ratio of the grid, the dispersion and coalescence state of the fluid inside the tower can be optimized to adapt to materials with different physical properties.

[0055] Product discharge: After sufficient countercurrent contact and mass transfer, the extracted bee product extract has now become the raffinate phase, with the target component content at a very low level, flowing to the bottom of the tower and being discharged through the heavy liquid outlet 102.

[0056] The extract loaded with the target anti-tumor component has now become the extraction phase. The extract rich in the target component rises to the top of the column and is discharged through the clear liquid outlet 101, entering the subsequent solvent recovery and product purification processes.

[0057] Bee product extract enters the extraction tower 1 through heavy liquid inlet 103, and extract enters the extraction tower 1 through clear liquid inlet 104. Then, the output of motor 302 drives the first drive gear 304 to rotate, which in turn drives the rotating shaft 303 and the turntable 306 to rotate, so that the bee product extract comes into contact with the extract. The bee product extract is discharged through heavy liquid outlet 102, and the extract is discharged through clear liquid outlet 101. Hot water is introduced into the lower temperature control jacket 203, the middle temperature control jacket 202, and the upper temperature control jacket 201 through the hot water circulation inlet pipe 204. The hot water inside the upper temperature control jacket 201, the middle temperature control jacket 202, and the lower temperature control jacket 203 is discharged through the hot water circulation outlet pipe 205 for reheating, thereby heating and controlling the temperature of the three zones inside the extraction tower 1. The circulating hot water enters the shaft 303 and the turntable 306 through the first rotary joint 307, and then exits through the second rotary joint 308. After being reheated, it is introduced again to adjust the temperature of the product leachate and extract. By rotating the rotating column 406, the rotating column 406 drives the threaded rod 402 to rotate via two bevel gears 407. The threaded rod 402 drives the slider 403 and rack 405 to move upward. The rack 405 drives two second drive gears 513 to rotate. The second drive gears 513 drive the worm 509 and worm wheel 511 to rotate. The worm wheel 511 drives the rotating shaft 510 to rotate. The rotating shaft 510 drives the transmission gear 512 to rotate. The transmission gear 512 drives the gear ring 507 to rotate. The gear ring 507 drives the rotating ring 504 to rotate. This causes the through groove 506 on the rotating ring 504 to move, causing the positioning ring 505 to be misaligned with the through groove 506 on the rotating ring 504, thus adjusting the size of the hole.

[0058] Example 3 The difference between this embodiment and the above embodiments is that the temperature control device 2 on the outside of the equipment cools the tower wall through cold water circulation, providing and maintaining the optimal temperature for the extraction process.

[0059] Meanwhile, the turntable 306 is designed as a hollow structure, communicating with the interior of the rotating shaft 303 to form another independent temperature control channel. The cooling medium enters the rotating shaft 303 and the turntable 306 through the first rotary joint 307, and then flows out from the second rotary joint 308, forming a circulation.
