Description

Technical Field

[0001] The present invention relates to the technical field of ginseng extraction, and particularly relates to an extraction device and process for producing ginseng extract. Background Art

[0002] In the prior art, the extraction of ginseng extract is generally carried out in the following ways: ultrasonic-assisted extraction, enzymatic hydrolysis method, and supercritical CO2 extraction. Supercritical CO2 extraction uses high-pressure CO2 as a solvent to selectively extract liposoluble components without solvent residues, which is suitable for the extraction of high-purity products.

[0003] Ginseng materials contain multiple components, and it is necessary to extract multiple components. The extraction means in the prior art is to extract all components at once, and then separate different components from the extract, which is relatively complex and cumbersome, affecting the processing efficiency. Moreover, multiple solvents need to be added to achieve separation, which will affect the concentration and cleanliness of the components. If manual separation of solids and liquids is carried out after each component is extracted, it is also cumbersome, and it is necessary to refill the required supercritical CO2 during manual separation, affecting the separation efficiency.

[0022] A ball is rotatably connected to the bottom end of the material dialing cylinder.

[0023] An extraction process for producing ginseng extract, which is applicable to the above-mentioned extraction device for producing ginseng extract, includes the following steps:

[0024] Step 1: Add ginseng materials into the kettle body through the feeding door, then add entrainer through the feeding pipe. Start the heater to heat the materials and the entrainer to the specified temperature, and then start the air supply pipe to fill supercritical CO2 into the kettle body. The temperature sensor and pressure sensor of the controller respectively obtain the temperature of the liquid in the kettle body and the pressure in the kettle body, and extract the components generated by the ginseng materials under this condition by controlling the temperature and pressure;

[0025] Step 2: Open the electric valve through the controller, and start the cylinder to push the material supporting plate, the electric valve, the first filter screen, the annular part, the second filter screen, the liquid and the ginseng materials to move upward. When moving upward, the supercritical CO2 above the liquid will push the liquid to pass through the first filter screen due to the pressure. The first filter screen filters the ginseng materials, so that the ginseng materials are located on the top of the material supporting plate. The extract enters the lower part of the material supporting plate through the material port, so that the extract and the ginseng materials are separated;

[0026] Step 3: After the liquid level sensor detects that the material supporting plate has moved above the liquid level, it continues to move up a specified distance to reserve a space for liquid filling. When moving up, the clamping block inserts into the interior of the clamping shell and squeezes the anti-blocking plate to compress Spring 4. Start the motor to drive the thick gear to rotate forward. The second rotating shaft drives the sleeve and the clamping block to rotate through the second slider. The clamping block drives the clamping shell, the material supporting plate, the annular part and the second filter net to rotate. The ginseng material and the remaining liquid move closer to the annular part due to centrifugal force. The liquid passes through the second filter net and enters the second liquid inlet cavity, and then flows into the reserved space below through the first liquid inlet cavity and the material port. Then close the electric valve. After the electric valve is closed, the material supporting plate separates the supercritical CO2 that is not fused in the liquid above from the extraction liquid below. Then open the discharge pipe to let the extraction liquid containing this component flow out of the kettle body;

[0027] Step 4: The controller controls the motor to drive the thick gear to rotate in reverse. The reverse rotation of the thick gear meets the rotation direction of the second one-way gear driving the rotating cylinder. The rotation of the rotating cylinder drives the mounting block to rotate. The mounting block drives the reciprocating screw rod and the guide rod on one side to rotate accordingly. When the reciprocating screw rod rotates, Gear 2 meshes with the outermost tooth slot 2, causing Gear 2 to rotate on its own while following the rotation of the reciprocating screw rod. The rotation of the reciprocating screw rod drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the connecting plate, Spring 1, the first slider and the material pushing rod to rotate. When the first rotating shaft rotates around the center, Gear 2 makes it rotate on its own, causing the first rotating shaft to drive the connecting plate, Spring 1, the first slider, the material pushing rod, the material pushing cylinder, the material throwing plate and the ball to rotate, spreading the material piled up at the edge due to centrifugal force towards the middle. When the rotating cylinder rotates one circle, Gear 1 meshes with the arc-shaped rack, causing the reciprocating screw rod to rotate. The rotation of the reciprocating screw rod makes the moving block move a specified distance. During the moving process, the moving block drives the first rotating shaft and Gear 2 to enter between the two rings from the residual notch. After entering, Gear 2 meshes with tooth slot 1, and then the second spreading operation is carried out to further spread the material spread in the first circle towards the middle. After rotating one circle, the moving block continues to move along the reciprocating screw rod and meshes with the tooth slot 2 of the second ring, performing the spreading operation of the third circle. According to the above steps, the ginseng material centrifuged to the edge is spread out again;

[0028] Step 5: When the first rotating shaft drives the material pushing rod to rotate, Spring 1 pulls the first slider and the material pushing rod so that the top of the material pushing rod closely adheres to the edge of the circular plate and rotates around the circular plate. Using the arc-shaped groove on the circular plate, Spring 1 pulls the first slider and the material pushing rod to move back and forth. When the material pushing rod rotates, it drives the material pushing cylinder and the material throwing plate to move back and forth. The vibration generated by the back-and-forth movement causes the material throwing plate to swing around the connection point. The swinging of the material throwing plate strikes the material pushing cylinder, dispersing the ginseng material;

[0029] Step 6: Start the cylinder to move the material supporting plate downward for resetting. When resetting, squeeze out the extraction liquid below from the kettle body, then re-add the entrainer into it, and start the heater for heating. The controller detects the pressure of the supercritical CO2 inside, and then supplements it according to the remaining content of the supercritical CO2. The controller detects the temperature and pressure to make the temperature condition and pressure condition meet the extraction of the next component. After extraction, separate according to the above steps, and then extract other components until all the required components are extracted one by one. After the extraction is completed, clean the ginseng material residue through the feeding door.

[0030] Compared with the existing technology, the beneficial effects of the present invention are:

[0031] The present invention extracts various components of ginseng materials in segments. After the extraction of each component is completed, the liquid is isolated from the un-fused supercritical CO2. After the liquid is discharged, the isolated supercritical CO2 is reused. When extracting the next component, the amount of supercritical CO2 filled is reduced, improving the efficiency of segmental extraction. After the extraction of each component, the component is collected separately, avoiding all components being mixed together, and no further separation steps are required, improving the extraction efficiency. The centrifugal mechanism is used to separate the solid and liquid, reducing the residue of the component, and avoiding the residue of the component being mixed with other components to affect the purity of the component. While ensuring the purity of the component, the centrifuged ginseng material is evenly spread out, and the ginseng material is loose with gaps, ensuring sufficient contact between the liquid and the solid, and improving the extraction speed and extraction completeness of the component.

[0063] An extraction process for producing ginseng extract, which is applicable to the above-mentioned extraction device for producing ginseng extract, includes the following steps:

[0064] Step 1: Add ginseng materials into the kettle body 12 through the feeding door 17, then add an entrainer through the feeding pipe 15, start the heater 18 to heat the materials and the entrainer to a specified temperature, and then start the gas supply pipe 14 to fill the kettle body 12 with supercritical CO2. The temperature sensor and pressure sensor of the controller 13 respectively obtain the temperature of the liquid in the kettle body 12 and the pressure in the kettle body 12, and extract the components generated by the ginseng materials under this condition by controlling the temperature and pressure;

[0065] Step 2: After the extraction of this component is completed, the extraction of the next component is required. Open the electric valve 34 through the controller 13, and start the cylinder 33 to push the material supporting plate 31, the electric valve 34, the first filter screen 35, the annular part 48, the second filter screen 49, the liquid and the ginseng materials to move upward. When moving upward, the supercritical CO2 above the liquid will push the liquid through the first filter screen 35 due to the pressure. The first filter screen 35 filters the ginseng materials, making the ginseng materials located at the top of the material supporting plate 31. The extract enters the lower part of the material supporting plate 31 through the material port 32, realizing the separation of the extract and the ginseng materials;

[0066] Step 3: During the upward movement, the liquid level sensor is always working. When the liquid level sensor detects that the material supporting plate 31 has moved above the liquid level, continue to move upward a specified distance to reserve a space for liquid filling. When moving upward, the block 47 is inserted into the inside of the shell 412, and squeezes the anti-blocking plate 414 to compress the spring four 413. Start the motor 21 to drive the thick gear 22 to rotate forward. The second rotating shaft 41 drives the sleeve 45 and the block 47 to rotate through the second slider 44. The block 47 drives the shell 412, the material supporting plate 31, the annular part 48 and the second filter screen 49 to rotate. The ginseng materials and the remaining liquid approach the annular part 48 due to the centrifugal force. The liquid passes through the second filter screen 49 and enters the second liquid inlet cavity 410, and then flows into the reserved space below through the first liquid inlet cavity 411 and the material port 32. Then close the electric valve 34. After the electric valve 34 is closed, the material supporting plate 31 separates the supercritical CO2 that is not fused in the liquid above from the extract below. Then open the discharge pipe 16 to let the extract containing this component flow out of the kettle body 12;

[0067] Step 4: When the top of the material supporting plate 31 moves upward, it contacts the ball 19. When the liquid level is relatively high, it will push the ball 19 and the material feeding cylinder 516 upward, compressing the second spring 517. The controller 13 controls the motor 21 to drive the thick gear 22 to reverse. The reverse rotation of the thick gear 22 meets the rotation direction for the one-way gear two 52 to drive the rotating cylinder 51 to rotate. The rotation of the rotating cylinder 51 drives the mounting block 53 to rotate. The mounting block 53 drives the reciprocating screw rod 54 and the guide rod 56 on one side to rotate accordingly. When the reciprocating screw rod 54 rotates, the gear two 510 meshes with the outermost tooth groove two 523, causing the gear two 510 to rotate around its own axis while following the rotation of the reciprocating screw rod 54. The rotation of the reciprocating screw rod 54 drives the rotation of the first rotating shaft 59. The rotation of the first rotating shaft 59 drives the rotation of the connecting plate 511, the first spring 514, the first slider 513, and the material feeding rod 515. When the first rotating shaft 59 rotates around the common center, the gear two 510 makes it rotate around its own axis, causing the first rotating shaft 59 to drive the rotation of the connecting plate 511, the first spring 514, the first slider 513, the material feeding rod 515, the material feeding cylinder 516, the material throwing plate 518, and the ball 519, spreading the materials accumulated at the edge due to centrifugal force towards the middle. When the rotating cylinder 51 rotates one circle, the gear one 55 meshes with the arc-shaped rack 57, causing the reciprocating screw rod 54 to rotate. The rotation of the reciprocating screw rod 54 makes the moving block 521 move a specified distance. During the moving process, the moving block 521 drives the first rotating shaft 59 and the gear two 510 to enter between the two rings 520 from the residual notch 524. After entering, the gear two 510 meshes with the tooth groove one 522, and then the second circle of spreading operation is carried out, further spreading the materials spread in the first circle towards the middle. After rotating one circle, the moving block 521 continues to move along the reciprocating screw rod 54 and meshes with the tooth groove two 523 of the second ring 520, carrying out the spreading operation of the third circle. According to the above steps, the ginseng materials centrifuged to the edge are re-spread;

[0068] Step 5: When spreading, the ball 519 rolls on the material supporting plate 31 to reduce friction. When the first rotating shaft 59 drives the material feeding rod 515 to rotate, the first spring 514 pulls the first slider 513 and the material feeding rod 515 so that the top end of the material feeding rod 515 closely adheres to the edge of the circular plate 525 and rotates around the circular plate 525. Using the arc-shaped groove on the circular plate 525, the first spring 514 pulls the first slider 513 and the material feeding rod 515 to move back and forth. When the material feeding rod 515 rotates, it drives the material feeding cylinder 516 and the material throwing plate 518 to move back and forth. The vibration generated by the back-and-forth movement causes the material throwing plate 518 to swing around the connection point. The swinging of the material throwing plate 518 strikes the material feeding cylinder 516, dispersing the ginseng materials. When the moving block 521 moves to the thread end of the reciprocating screw rod 54 and then moves back, the second round of loosening is carried out during the backward movement. Loosening the ginseng materials can enable the liquid to fully contact the materials, avoiding difficulties in extraction due to agglomeration;

[0069] Step 6: Start the cylinder 33 to move the material supporting plate 31 downward for resetting. When resetting, squeeze out the extraction liquid below from the kettle body 12, then re-add the entrainer into the interior, and start the heater 18 for heating. The controller 13 detects the pressure of the supercritical CO2 inside, and then supplements it according to the remaining content of the supercritical CO2. The controller 13 detects the temperature and pressure to make the temperature condition and pressure condition meet the extraction of the next component. After extraction, separate according to the above steps, and then perform the extraction of other components until all the required components are extracted one by one. After the extraction is completed, clean the ginseng material residue through the feeding door 17;

[0070] This application extracts various components of the ginseng material in segments. After the extraction of each component is completed, the liquid is isolated from the un-fused supercritical CO2. After the liquid is discharged, the isolated supercritical CO2 is reused. When performing the extraction of the next component, the amount of supercritical CO2 charged is reduced to improve the efficiency of segmented extraction. After the extraction of each component, the component is collected separately to avoid mixing all the components together, without the need for further separation steps, improving the extraction efficiency. The centrifugal mechanism is used to separate the solid and liquid, reducing the residue of the components and avoiding the mixing of the residues with other components, which affects the purity of the components. While ensuring the purity of the components, the centrifuged ginseng material is evenly spread out and the ginseng material is loose with gaps to ensure sufficient contact between the liquid and the solid, improving the extraction speed and extraction completeness of the components.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

When moving upward, the supercritical CO2 above the liquid will push the liquid through the filter screen 1 (35) due to the pressure. The filter screen 1 (35) filters the ginseng material so that the ginseng material is located at the top of the supporting plate (31). The extract enters the bottom of the supporting plate (31) through the material port (32), so that the extract and the ginseng material are separated. Step 3: When the liquid level sensor detects that the support plate (31) has moved up to above the liquid level, it continues to move up a specified distance to reserve space for liquid filling. When moving up, the block (47) is inserted into the inside of the card shell (412), and the anti-blocking plate (414) is squeezed to compress the spring four (413), and the motor (21) is started to drive the thick gear (22) to rotate forward, and the rotating shaft (41) drives the sleeve (45) and the block (47) to rotate through the slider (44), and the block (47) drives the card shell (412) and the support plate (31), the ring member (48) and The second filter screen (49) rotates, and the ginseng material and the remaining liquid are moved toward the ring member (48) due to centrifugal force. The liquid passes through the second filter screen (49) and enters the second liquid inlet chamber (410), and then flows into the reserved space below through the first liquid inlet chamber (411) and the material port (32), and then the electric valve (34) is closed. After the electric valve (34) is closed, the supporting plate (31) separates the supercritical CO2 that is not fused in the liquid above from the extract below, and then the discharge pipe (16) is opened to allow the extract containing the component to flow out of the kettle body (12); Step 4: The controller (13) controls the motor (21) to drive the thick gear (22) to rotate in the reverse direction. The thick gear (22) rotates in the reverse direction to satisfy the direction in which the one-way gear 2 (52) drives the rotating drum (51) to rotate. The rotating drum (51) rotates to drive the mounting block (53). The mounting block (53) drives the reciprocating screw (54) and the guide rod (56) on one side to rotate accordingly. When the reciprocating screw (54) rotates, the gear 2 (510) meshes with the outermost tooth groove 2 (523), so that the gear When the wheel 2 (510) rotates following the rotation of the reciprocating screw (54), the rotation of the reciprocating screw (54) drives the rotation of the rotating shaft 1 (59), and the rotation of the rotating shaft 1 (59) drives the connecting plate (511), the spring 1 (514), the slider 1 (513) and the material-moving rod (515) to rotate. When the rotating shaft 1 (59) follows the revolution, the gear 2 (510) makes it rotate, so that the rotating shaft 1 (59) drives the connecting plate (511), the spring 1 (514), the slider 1 (513) and the material-moving rod (515) to rotate. ), the material-dispensing rod (515), the material-dispensing cylinder (516), the material-dispensing plate (518) and the ball bearing (519) rotate to spread the materials accumulated on the edge due to centrifugal force to the middle.
