Description

Technical Field

[0001] The invention belongs to the technical field of plant fermentation equipment, in particular to an ultrasonic plant fermentation extraction and separation equipment. Background Art

[0002] "Plant extracts" are products that use plants as raw materials, and are produced by directing and concentrating one or more active ingredients in plants through physical and chemical extraction and separation processes according to the needs of the extraction purpose, without changing the structure of the active ingredients. According to the different components of the extracted plants, glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc. are formed; according to different properties, they can be divided into plant oils, extracts, powders, crystals, etc.

[0003] Ultrasonic technology is a new extraction technology in recent years, with great application prospects. Ultrasonic extraction uses the strong cavitation effect, mechanical vibration, disturbance effect, high acceleration, emulsification, diffusion, crushing and stirring effects produced by ultrasonic radiation pressure to increase the frequency and speed of molecular movement of substances and increase the penetration of solvents, thereby accelerating the entry of target components into the solvent and promoting the extraction process.

[0004] The ultrasonic plant fermentation extraction and separation equipment disclosed by the Chinese patent publication number CN217939219U has the following technical scheme points: including an ultrasonic extraction instrument body, the ultrasonic extraction instrument body including a base and a connection platform, the connection platform is fixedly connected to the upper surface of the base, a glass tube is placed on the upper surface of the connection platform, an elastic airbag is fixedly connected to the lower surface of the connection platform, a connection plate is fixedly connected to the lower surface of the connection platform, and a second telescopic rod is fixedly connected to the lower surface of the connection plate. The utility model solves the problem that the existing ultrasonic extraction and separation equipment is inconvenient to limit the glass tubes of different diameters during use, and if the glass tube is greatly displaced due to collision with personnel during extraction, it is easy to collide with the ultrasonic extraction and separation equipment, thereby causing the glass tube to break and the problem of waste of raw materials.

[0005] However, the above technology often has the following defects: first, after ultrasonic extraction of plants, it is often necessary to mix and stir with a solvent to form a fermentation step, so that the extract is centrifuged, and the above extraction and separation mechanism is difficult to apply the ultrasonic generation technology to the fermentation stirring step, resulting in the separation of the vibration generated by the stirring and ultrasonic waves, making it difficult to further expand the stirring efficiency and increase the degree of plant cell rupture.

[0006] To this end, the present invention provides an ultrasonic plant fermentation extraction and separation device. Summary of the invention

[0007] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0008] The technical solution adopted by the present invention to solve its technical problems is: an ultrasonic plant fermentation extraction and separation device described in the present invention comprises an ultrasonic device body, a fermentation chamber is arranged in the ultrasonic device body, a fermentation stirring module and a centrifugal vibration unit installed on the fermentation stirring module are arranged in the fermentation chamber, wherein the ultrasonic vibration generated by the ultrasonic device body is specifically used in the plant fermentation extraction and separation device as follows: the ultrasonic transducer converts electrical energy into mechanical energy to generate ultrasonic vibration, which causes the movement of substances in plant tissue cells, causes the cytoplasm to flow, the cells to oscillate, rotate, and rub, thereby producing a cell massage effect, which can change the permeability of the cell membrane, change the internal structure of the cell, and accelerate the rate at which the ethanol aqueous solution enters the cell, thereby improving the extraction rate, and the mechanical vibration directly generated by the ultrasonic device body is transmitted to the fermentation chamber, and this process consumes too much energy and the vibration effect is greatly reduced. To solve this problem, the centrifugal vibration unit described in the present application transmits the mechanical vibration generated by the piezoelectric material inside the ultrasonic device body through the connecting unit, and a filtering unit is arranged at the bottom of the fermentation stirring module; The fermentation stirring module includes a fermentation box arranged in a fermentation chamber, a hollow cylinder is arranged inside the fermentation box, the outer wall of the hollow cylinder and the fermentation box form a resonance area, a stirring shaft is axially rotated at the center of the hollow cylinder, a stepping motor is installed on the top of the stirring shaft through a coupling, the stirring shaft is connected to a driving gear through a connecting key, and centrifugal vibration units are arranged on both sides of the driving gear. It should be noted that the present application uses ethanol-water solution to heat and stir the plant raw materials after supercritical extraction, centrifuge the extract, filter the upper clear liquid to remove excess impurities, reduce the pressure of the filtrate to recover ethanol, and concentrate the filtrate to a paste. The present application aims to further improve and optimize the stirring extraction efficiency and the decomposition rate of the plant cell wall.

[0009] A further improvement of the technical solution of the present invention is that the centrifugal vibration unit includes driven gears arranged on both sides of the driving gear, and the two groups of driven gears are respectively connected with screws through connecting keys, and the two groups of screws are vertically rotatably installed at the top of the hollow cylinder, and the two groups of nut parts are threadedly connected to the screws. Reinforcement rods are welded on the left and right ends of the two groups of nut parts, and the other end of each group of reinforcement rods passes through the top of the hollow cylinder into the cylinder. Each group of reinforcement rods is slidably connected to the hollow cylinder and a sealing member is arranged at the penetration point. After the driven gear is driven by the driving gear, the screw rotates and the nut part threadedly connected thereto rises and falls, so the connected reinforcement rod passes through the hollow cylinder and rises and falls in the cylinder.

[0010] A further improvement of the technical solution of the present invention lies in that: a tension spring is fixedly sleeved on one end of each group of reinforcement rods away from the screw rod, and one end of each group of tension springs away from the corresponding reinforcement rod is installed in an installation groove of a lifting base, the lifting base is circular and the side wall is in contact with the inner end surface of the hollow cylinder, and a linkage seat is arranged in a circle center array at the inner wall of the lifting base, a through opening is arranged in the middle of each linkage seat, and the other end of each linkage seat is welded to the stirring shaft. It should be noted that the reinforcement rod is pulled by the tension spring, so the stirring shaft is connected with the linkage seat during the stirring process, so that the lifting base is lifted and lowered and rotated at the same time. The direction of movement of the stepper motor in the above-mentioned medium represents the lifting direction of the nut part. When the tension spring curls under the action of the torque force, when the direction of the stepper motor rotates, the tension spring quickly releases the elastic potential energy and curls again, providing a linkage basis for the lifting base to follow the rotation of the stirring shaft; therefore, the present application shortens the fermentation time and improves the stirring efficiency of the plant and the ethanol-water solution in the fermentation tank through the phenomenon that the lifting base follows the lifting of the nut part, and cooperates with the linkage to make the lifting base rotate while lifting, further expanding the fermentation efficiency, and can complete the scraping operation of the hollow cylinder to avoid the adhesion of the ethanol-water solution and the like to the cylinder wall.

[0011] A further improvement of the technical solution of the present invention is that in order to integrate mechanical vibration with stirring operation and provide the required assistance for the decomposition and fermentation of plant cell walls, a curved rod is arranged between adjacent linkage seats, and each curved rod is fixedly sleeved with an energy storage spring, and one end of each energy storage spring is fixedly connected to a release impact block sliding on the corresponding curved rod, and vibration plates are welded on both sides of each group of linkage seats, and each vibration plate is welded with a vibration expansion plate with a protrusion fitting thereon. In the above, the present application gradually deviates to the direction of rotation under centrifugal rotation through the energy storage spring, and the energy storage spring is acted upon by centrifugal force and resistance of ethanol aqueous solution at the same time. The energy storage spring completes energy storage, and quickly releases energy after the stepping motor changes the direction of rotation. After consuming part of the capacity to resist resistance, the remaining energy is released by the release impact block to impact on the vibration plate, and the vibration plate diffuses vibration, so that the stirred plants and ethanol aqueous solution oscillate rapidly, further accelerating the decomposition of plant cell walls and the degree of oscillation in the hollow cylinder.

[0012] Each vibration plate is connected to a vibration expansion plate facing away from the linkage seat, and the vibration expansion plate extends in a direction away from the linkage seat. The vibration expansion plate includes a plurality of vibration expansion parts connected in sequence in a direction away from the linkage seat, and the cross-sectional shape of the vibration expansion part is arc-shaped, and the arc-shaped protrusion of the vibration expansion part protrudes in the direction away from the linkage seat.

[0013] The thickness of each vibration expanding portion is reduced in a direction away from the linkage seat, and the arc radius of each vibration expanding portion 221 is gradually expanded in a direction away from the linkage seat.

[0014] A further improvement of the technical solution of the present invention is that: the stirring shaft is arranged on the axis of the hollow cylinder and is arrayed with stirring rods of the same number as the linkage seat, the stirring rods are respectively located inside the through-hole and in the vertical direction of the through-hole, and stirring blades for expanding the stirring range are welded between adjacent stirring rods. In order to reduce resistance, each stirring rod and stirring blade is provided with a plurality of drag reducing holes for reducing resistance.

[0015] A further improvement to the technical solution of the present invention is that: in order to avoid interference between the movement of the stirring rod and the linkage seat during stirring and rotation, each of the stirring rods is respectively arranged at the through-hole and the longitudinal position of the through-hole in the corresponding linkage seat, and the linkage seat is raised and lowered at the stirring rod through the through-hole to avoid the stirring rod colliding with the linkage seat, and the length of each of the stirring rods and stirring blades from the center of the stirring shaft is less than the length of the outer inner wall of the linkage seat from the center of the stirring shaft.

[0016] A further improvement of the technical solution of the present invention is that: the filtration unit includes a conical feed hopper arranged at the bottom of the hollow cylinder, the conical feed hopper is fixedly connected to the hollow cylinder, and a plurality of feed pipes are fixedly installed on the conical feed hopper, each of the feed pipes is provided with an electrically controlled valve, the conical feed hopper is divided into a feed layer, a vibration layer and a filtration layer from top to bottom, a plurality of annular pipes connected to the feed pipe are arranged in the feed layer, and the plurality of annular pipes are connected by a connecting pipe, and a resonance spring is arranged between the outermost annular pipe and the inner wall of the conical feed hopper and the adjacent annular pipes, wherein the arrangement of the annular pipe can further slow down the feed speed and prolong the residence time of the plant raw material and the ethanol aqueous solution in the pipe, so that the ultrasonic mechanical vibration transmitted by the connecting unit further decomposes the plant raw material, and cooperates with the fermentation stirring module and the centrifugal vibration unit to reduce the amount of ethanol aqueous solution solvent used and make the amount of ethanol aqueous solution used more moderate, so that the active compounds are less destroyed and the extraction yield is high.

[0017] A further improvement of the technical solution of the present invention is that the vibration layer transmits the mechanical vibration generated by the piezoelectric material inside the main body of the ultrasonic device through the connecting unit, and the filter screen can be detachably installed on the filter layer.

[0018] A further improvement of the technical solution of the present invention is that the connecting unit includes a conductive tube connected to the piezoelectric material, each of the conductive tubes is fixedly mounted with a resonance tube, the other end of the resonance tube is welded with a hollow ball, and the interior of the hollow ball is filled with irregularly arranged collision balls.

[0020] 2. The ultrasonic plant fermentation extraction and separation equipment described in the present invention shortens the fermentation time and improves the stirring efficiency of the plants and the ethanol-water solution in the fermentation tank by virtue of the phenomenon that the lifting base follows the lifting of the nut. The lifting base is coordinated to rotate while being lifted and lowered, thereby further increasing the fermentation efficiency. The equipment can also complete the scraping operation of the hollow cylinder to prevent the ethanol-water solution from sticking to the cylinder wall.

[0021] 3. The ultrasonic plant fermentation extraction and separation equipment described in the present invention can further slow down the feeding speed and prolong the residence time of the plant raw material and the ethanol aqueous solution in the pipeline through the setting of the annular pipeline. Therefore, the ultrasonic mechanical vibration transmitted by the connecting unit further decomposes the plant raw material. The fermentation stirring module and the centrifugal vibration unit can reduce the amount of ethanol aqueous solution solvent and make the amount of ethanol aqueous solution more gentle, so that the active compounds are less destroyed and the extraction yield is high.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Embodiment 1: Figures 1 to 8 As shown, an ultrasonic plant fermentation extraction and separation device described in an embodiment of the present invention includes an ultrasonic device body 1, wherein a fermentation chamber is arranged in the ultrasonic device body 1, wherein a fermentation stirring module and a centrifugal vibration unit installed on the fermentation stirring module are arranged in the fermentation chamber, wherein the ultrasonic vibration generated by the ultrasonic device body 1 is specifically used in the plant fermentation extraction and separation device as follows: the ultrasonic transducer converts electrical energy into mechanical energy to generate ultrasonic vibration, which causes the movement of substances in plant tissue cells, causes the cytoplasm to flow, the cells to oscillate, rotate, and rub, thereby producing a cell massage effect, which can change the permeability of the cell membrane, change the internal structure of the cell, and accelerate the rate at which the ethanol aqueous solution enters the cell, thereby improving the extraction rate, and the mechanical vibration directly generated by the ultrasonic device body 1 is transmitted to the fermentation chamber, and this process consumes too much energy, and the vibration effect is greatly reduced. To solve this problem, the centrifugal vibration unit described in the present application transmits the mechanical vibration generated by the piezoelectric material inside the ultrasonic device body 1 through the connecting unit, and a filtering unit is arranged at the bottom of the fermentation stirring module; The fermentation stirring module includes a fermentation box 2 arranged in a fermentation chamber, a hollow cylinder 3 is arranged inside the fermentation box 2, the outer wall of the hollow cylinder 3 and the fermentation box 2 form a resonance area, a stirring shaft 4 is axially rotated at the center of the hollow cylinder 3, a stepping motor 5 is installed on the top of the stirring shaft 4 through a coupling, the stirring shaft 4 is connected to a driving gear 6 through a connecting key, and centrifugal vibration units are arranged on both sides of the driving gear 6. It should be noted that the present application uses ethanol-water solution to heat and stir the plant raw materials after supercritical extraction, centrifuge the extract, filter the supernatant, remove excess impurities, reduce the pressure of the filtrate to recover ethanol, and concentrate the filtrate to a paste. The present application aims to further improve and optimize the stirring extraction efficiency and the decomposition rate of the plant cell wall.

[0027] like Figures 1 to 5 As shown, the centrifugal vibration unit includes a driven gear 10 arranged on both sides of the driving gear 6, and the two groups of the driven gears 10 are respectively connected with a screw rod 11 through a connecting key, and the two groups of the screw rods 11 are vertically rotatably installed at the top of the hollow cylinder 3, and the two groups of the screw rods 11 are threadedly connected to the nut members 12, and the left and right ends of the two groups of the nut members 12 are respectively welded with reinforcement rods 13, and the other end of each group of the reinforcement rods 13 passes through the hollow cylinder 3 and is used to connect the lifting and tensioning springs 14 to strengthen the tightness of the connection with the tensioning springs 14, and each group of the reinforcement rods 13 is slidably connected to the hollow cylinder 3 and a sealing member is arranged at the penetration point, wherein after the driven gear 10 is driven by the driving gear 6, the screw rod 11 rotates and the nut member 12 threaded thereon is lifted and lowered, so the connected reinforcement rod 13 passes through the hollow cylinder 3 and is lifted and lowered in the cylinder.

[0028] like Figures 4 to 5As shown, one end of each group of reinforcement rods 13 away from the screw rod 11 is fixedly sleeved with a tension spring 14, and one end of each group of tension springs 14 away from the corresponding reinforcement rod 13 is installed in the installation groove of the lifting base 15. The lifting base 15 is circular and the side wall is in contact with the inner end surface of the hollow cylinder 3. The inner wall of the lifting base 15 is provided with a linkage seat 16 in the center array, and each linkage seat 16 is provided with a through hole 17 in the middle, and the other end of each linkage seat 16 is welded to the stirring shaft 4. It should be noted that the reinforcement rod 13 is pulled by the tension spring 14, so the stirring shaft 4 is connected to the linkage seat 16 during the stirring process, so that the lifting base 15 is lifted and lowered at the same time. Rotation, the direction of rotation of the stepper motor 5 in the above-mentioned represents the lifting direction of the nut part 12. When the tension spring 14 curls under the action of the torque force, when the stepper motor 5 rotates in the direction, the tension spring 14 quickly releases the elastic potential energy and curls again, providing a linkage basis for the lifting base 15 to follow the rotation of the stirring shaft 4; therefore, the present application shortens the fermentation time and improves the stirring efficiency of the plant and the ethanol-water solution in the fermentation tank through the phenomenon that the lifting base 15 follows the lifting of the nut part 12, and cooperates with the linkage to make the lifting base 15 rotate while lifting, further expanding the fermentation efficiency, and can complete the scraping operation of the hollow cylinder 3 to avoid the adhesion of the ethanol-water solution and the like to the cylinder wall.

[0029] like Figure 5 As shown, in order to integrate mechanical vibration with stirring operation and provide the required assistance for the decomposition and fermentation of plant cell walls, a curved rod 18 is arranged between adjacent linkage seats 16, and each curved rod 18 is fixedly sleeved with an energy storage spring 19, and one end of each energy storage spring 19 is fixedly connected to a release impact block 20 sliding on the corresponding curved rod 18, and vibration plates 21 are welded on both sides of each group of linkage seats 16, and each vibration plate 21 is welded with a protruding and fitting expansion plate 22. In the above, the energy storage spring 19 is gradually biased towards the rotation direction under centrifugal rotation. The energy storage spring 19 is acted upon by centrifugal force and resistance of ethanol aqueous solution at the same time. The energy storage spring 19 completes energy storage, and quickly releases energy after the stepping motor 5 changes the rotation direction. After consuming part of the capacity to resist the resistance, the remaining energy is hit on the vibration plate 21 through the release impact block 20, and the vibration plate 21 vibrates, so that the stirred plants and ethanol aqueous solution oscillate rapidly, further accelerating the decomposition of plant cell walls and the degree of oscillation in the hollow cylinder 3.

[0030] like Figures 4 to 6 As shown, the stirring shaft 4 is located inside the hollow cylinder 3 and is arrayed with stirring rods 7 of the same number as the linkage seat 16 on the axis. The stirring rods 7 are respectively located inside the through-hole 17 and in the vertical direction of the through-hole 17. Stirring blades 8 for expanding the stirring range are welded between adjacent stirring rods 7. In order to reduce resistance, each stirring rod 7 and stirring blade 8 is provided with a plurality of drag reducing holes 9 for reducing resistance.

[0031] like Figures 1 to 6 As shown, in order to avoid interference between the movement of the stirring rod 7 and the linkage seat 16 during stirring and rotation, each of the stirring rods 7 is respectively arranged at the through-hole 17 in the corresponding linkage seat 16 and at the longitudinal position of the through-hole 17, and the linkage seat 16 is raised and lowered at the stirring rod 7 through the through-hole 17. In order to avoid the stirring rod 7 colliding with the linkage seat 16, the length of each stirring rod 7 and stirring blade 8 from the center of the stirring shaft 4 is less than the length of the outer inner wall of the linkage seat 16 from the center of the stirring shaft 4.

[0032] Embodiment 2: Figures 7 and 8 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: the filtration unit comprises a conical hopper 23 arranged at the bottom of the hollow cylinder 3, the conical hopper 23 is fixedly connected to the hollow cylinder 3, and a plurality of feed pipes 24 are fixedly installed on the conical hopper 23, each of which is provided with an electric control valve 25, and the conical hopper 23 is divided into a feed layer 26, a vibration layer 27 and a filter layer 28 from top to bottom, and the feed layer 26 is provided with a plurality of annular pipes 29 connected to the feed pipe 24, and a plurality of annular pipes 29 are provided in the plurality of annular pipes 29 connected to the feed pipe 24. The annular pipes 29 are connected by connecting pipes, and a resonance spring 30 is arranged between the outermost annular pipe 29 and the inner wall of the conical discharge hopper 23 and the adjacent annular pipes 29, wherein the arrangement of the annular pipe 29 can further slow down the material discharge speed and prolong the residence time of the plant material and the ethanol aqueous solution in the pipe, so that the ultrasonic mechanical vibration transmitted by the connecting unit further decomposes the plant material, and cooperates with the fermentation stirring module and the centrifugal vibration unit to reduce the amount of ethanol aqueous solution solvent and make the amount of ethanol aqueous solution more gentle, so that the active compounds are less damaged and the extraction yield is high.

[0033] The vibration layer 27 transmits the mechanical vibration generated by the piezoelectric material inside the ultrasonic device body 1 through the connection unit, and the filter screen 31 is detachably mounted on the filter layer 28 .

[0034] like Figure 8 As shown, the connection unit includes a conductive tube 32 connected to the piezoelectric material, and a resonance tube 33 is fixedly installed on each conductive tube 32. A hollow ball 34 is welded to the other end of the resonance tube 33, and the interior of the hollow ball 34 is filled with irregularly arranged collision balls 35.

[0035] Working principle: The transducer converts electrical energy into mechanical energy to generate ultrasonic vibration. At this time, after the stirring shaft 4 is driven by the stepper motor 5, the driven gear 10 is driven by the driving gear 6, and the screw rod 11 rotates while the nut 12 threaded thereon is lifted and lowered. Therefore, the connected reinforcement rod 13 passes through the hollow cylinder 3 and is lifted and lowered in the cylinder. The reinforcement rod 13 is pulled by the tension spring 14. Therefore, during the stirring process, the stirring shaft 4 is connected to the linkage seat 16 to make the lifting base 15 lift and rotate at the same time. In this process, the energy storage spring 19 gradually deviates to the direction of rotation under the condition of centrifugal rotation, and the energy storage spring 19 gradually deviates to the direction of rotation. The energy spring 19 is acted upon by the centrifugal force and the resistance of the ethanol aqueous solution at the same time. The energy storage spring 19 completes the energy storage and quickly releases the energy after the stepping motor 5 changes the rotation direction. After consuming part of the energy to resist the resistance, the remaining energy is released by the impact block 20 to impact the vibration plate 21. The vibration plate 21 further diffuses the vibration through the specially shaped vibration expansion plate 22. At this time, the stirring rod 7 and the stirring blade 8 are still stirring and fermenting, achieving the integration and linkage of stirring and vibration. After stirring and fermenting to a certain extent, the electric control valve 25 is opened, and the prepared product gradually enters the annular pipe 29 from the discharge pipe 24, and is finally discharged through the filter layer 28.

[0036] Embodiment 3: Figures 9 and 10 As shown, compared with the first embodiment, each vibration plate 21 is connected to a vibration expansion plate 22 facing away from the linkage seat 16, and the vibration expansion plate 22 extends in a direction away from the linkage seat 16. The vibration expansion plate 22 includes a plurality of vibration expansion parts 221 connected in sequence in a direction away from the linkage seat 16, and the cross-sectional shape of the vibration expansion part 221 is arc-shaped, and the arc-shaped protrusion of the vibration expansion part 221 protrudes in the direction away from the linkage seat 16. Based on this, the vibration plate 21 will be transmitted to the vibration expansion plate 22, and since the cross-sectional shape of the vibration expansion part 221 is arc-shaped, the force generated during the vibration process is not only the force on the left and right sides, but also has the force in the up and down directions based on the arc surface of the vibration expansion part 221, which expands the dimension of the force direction, so that the stirred plants and ethanol aqueous solution can be more fully mixed.

[0037] Furthermore, the thickness of each vibration expansion part 221 is reduced in the direction away from the linkage seat 16, and the arc radius of each vibration expansion part 221 is gradually expanded in the direction away from the linkage seat 16. In this way, since the energy transfer process will be attenuated, in order to avoid excessive attenuation of the amplitude of the vibration expansion part 221 in the direction away from the linkage seat 16, the thickness of each vibration expansion part 221 is gradually reduced, and the vibration energy required by the vibration expansion part 221 is gradually reduced. At the same time, the arc radius of each vibration expansion part 221 is gradually expanded in the direction away from the linkage seat 16. Under the condition of ensuring that the same action area is covered, the connection nodes between two adjacent vibration expansion parts 221 are reduced, and the vibration energy attenuation is further reduced.

[0038] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
