Description

Technical Field

[0001] This invention relates to the field of safflower extraction technology, specifically a method for extracting and recovering safflower material liquid. Background Technology

[0002] Safflower extraction refers to the process of extracting the active ingredients from safflower, a traditional Chinese medicine with effects such as promoting blood circulation, removing blood stasis, and relieving pain. Safflower extract mainly contains safflower yellow pigment and safflower glycosides, which possess various biological activities such as antioxidant, anti-inflammatory, and anti-tumor properties. Extraction methods for safflower extract mainly include solvent extraction, supercritical fluid extraction, and microwave-assisted extraction. Solvent extraction is one of the most commonly used methods. It involves mixing safflower powder with a solvent, followed by stirring, soaking, and filtration to obtain the safflower extract. Safflower extract has various biological activities and pharmacological effects, and has broad application prospects in the fields of medicine, health products, and cosmetics.

[0003] However, the following defects were found during the separation of safflower liquid;

[0004] 1. During the separation of safflower material into liquid, some fine residues will be thrown out along with the filtrate, leaving some fine residues in the filtrate after separation. This presence of fine residues will affect the quality of the filtrate. In addition, these fine residues will adhere to the inside of the container during the separation of the filtrate, making them difficult to clean.

[0005] 2. After the safflower material liquid is separated, large pieces of residue will accumulate inside the separation equipment. If these large pieces of residue are not cleaned in time, the moisture in the residue will evaporate, causing the residue to become dry and easy to accumulate. In addition, the residue contains a large amount of organic matter and microorganisms. If it is not cleaned in time, the residue will decompose, and the deteriorated residue will contaminate the safflower material liquid to be separated later.

[0006] Therefore, this invention proposes a method for extracting and recovering safflower material liquid to compensate for and improve the deficiencies of the prior art. Summary of the Invention

[0015] S4. Concentration and Drying: Concentration is used to increase the concentration of active ingredients in the extract. Finally, the concentrated extract is dried to obtain a solid product.

[0016] The safflower material liquid extraction and recovery method using the above steps S1-S4 also involves a safflower material liquid extraction, recovery and separation device during the recovery process, including a base, a separation mechanism for centrifugally separating the safflower material liquid on the top of the base, and a recovery mechanism for collecting the residue after separation on the top of the base.

[0017] The separation mechanism includes an outer barrel fixedly connected to a base, an inner barrel inside the outer barrel, a separation hole on the side of the inner barrel, a rotating shaft fixedly connected to the bottom of the inner barrel, the rotating shaft passing through the bottom of the outer barrel, a motor fixedly connected to the base, the output end of the motor fixedly connected to the bottom of the rotating shaft, a filter assembly for cleaning fine residues in the safflower liquid on the outside of the inner barrel, and a cleaning mechanism for reducing safflower residues adhering to the inner wall of the outer barrel on the outside of the inner barrel.

[0018] Furthermore, the filter assembly includes a slot vertically formed on the outside of the inner barrel, a vertical rod inserted into the slot, and first horizontal rods fixedly connected to both ends of the vertical rod.

A threaded rod is fixedly connected to the middle of the first guide rod. A brush plate is threadedly connected to the outer side of the threaded rod. The brush plate extends downward into the inner barrel. The brush plate is slidably connected to the second guide rod. The inner barrel is also equipped with a collection component for cleaning the safflower residue after separation.

[0020] Furthermore, the collecting assembly includes a mounting block that is slidably sleeved on the outside of the first guide rod, the bottom of the mounting block being slidably sleeved on the outside of the second guide rod, a rack that is vertically slidably connected to the mounting block, a gear that is fixedly connected to the outside of the first guide rod, the gear meshing with the rack, a collecting frame that is fixedly connected to the bottom of the rack, a notch being provided on the side of the collecting frame, and limit blocks that are symmetrically fixedly connected to the first guide rod, the limit blocks being located on both sides of the mounting block.

[0023] (III) Beneficial Effects

[0024] Compared with known prior art, the technical solution provided by this invention has the following beneficial effects:

[0025] 1. Equipped with a separation mechanism, the safflower liquid is first separated by centrifugal force generated by the rotating inner barrel, thus quickly separating the safflower liquid. Then, the filtrate is agitated by the filter screen, which removes the fine residue from the filtrate, making the filtrate purer and reducing the presence of impurities. Finally, the fine residue is scraped off from the inner wall of the outer barrel by a scraper, and the scraped fine residue is collected by the filter screen to avoid secondary pollution.

[0026] 2. By configuring a recovery mechanism, firstly, large pieces of residue can be cleaned out of the equipment after the separation process is completed. This timely removal of residue effectively reduces its accumulation in the separation equipment, thereby lowering the likelihood of blockages and wear. This not only helps extend the service life of the separation equipment but also reduces maintenance and replacement costs. Secondly, it prevents residue from remaining in the separation equipment and deteriorating, thus avoiding contamination of the safflower liquid. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The present invention will be further described below with reference to embodiments.

[0041] like Figure 1 , Figure 2 and Figure 3 A method for extracting and recovering safflower liquid, comprising the following steps:

[0042] S1. Prepare raw materials: Select high-quality, impurity-free dried safflower materials, pre-treat the safflower by crushing or soaking, etc., to increase extraction efficiency.

[0043] S2. Soaking: The safflower material is heated together with the extraction solvent and then soaked to promote the dissolution of the liquid components into the extraction solvent;

[0044] S3, Separating the material liquid: The mixed solution after soaking is filtered, and the filtrate is the extract containing the active ingredients of safflower. During the separation process, the motor 25 drives the inner barrel 23 to rotate to separate the safflower material liquid and residue.

[0045] S4. Concentration and Drying: Concentration methods (such as evaporation, vacuum concentration, etc.) are used to increase the concentration of active ingredients in the extract. Finally, the concentrated extract is dried to obtain a solid product.

[0046] The safflower material liquid extraction and recovery method using the above steps S1-S4 also involves a safflower material liquid extraction, recovery and separation device during the recovery process, including a base 1, a separation mechanism 2 for centrifugal separation of safflower material liquid on the top of the base 1, and a recovery mechanism 3 for collecting the residue after separation on the top of the base 1.

[0047] See Figure 2 , Figure 3 , Figure 4 and Figure 5 The separation mechanism 2 includes an outer barrel 21 fixedly connected to the base 1, an inner barrel 23 inside the outer barrel 21, a separation hole 24 on the side of the inner barrel 23, a rotating shaft 22 fixedly connected to the bottom of the inner barrel 23, the rotating shaft 22 passing through the bottom of the outer barrel 21, a motor 25 fixedly connected to the base 1, the output end of the motor 25 being fixedly connected to the bottom of the rotating shaft 22, a filter assembly 26 for cleaning fine residues in the safflower liquid is provided on the outside of the inner barrel 23, and a cleaning mechanism 4 for reducing safflower residues adhering to the inner wall of the outer barrel 21 is also provided on the outside of the inner barrel 23.

[0048] In actual operation, the motor 25 drives the rotating shaft 22 to rotate counterclockwise, which in turn drives the inner barrel 23 to rotate counterclockwise quickly. During the rotation, centrifugal force is used to throw the safflower material liquid out of the separation hole 24, blocking large pieces of safflower residue inside the inner barrel 23. The thrown-out filtrate enters between the outer barrel 21 and the inner barrel 23.

[0049] See Figure 2 , Figure 7 and Figure 9 The filter assembly 26 includes a slot 266 vertically formed on the outside of the inner barrel 23. A vertical rod 261 is inserted into the slot 266. A first horizontal rod 262 is fixedly connected to both ends of the vertical rod 261. A U-shaped connector 264 is rotatably connected to the end of each first horizontal rod 262 away from the vertical rod 261. A second horizontal rod 263 is rotatably connected to the end of each U-shaped connector 264 away from the first horizontal rod 262. A connecting rod 265 is fixedly connected between the two second horizontal rods 263. A filter screen 267 is fixedly connected between the connecting rod 265 and the vertical rod 261. Two sets of filter components 26 are provided, and the two sets of filter components 26 are symmetrically installed on the outside of the inner barrel 23. When the first crossbar 262 and the second crossbar 263 are unfolded, the first crossbar 262 and the second crossbar 263 can be kept on the same straight line by using the U-shaped connector 264, so that the filter screen 267 can be fully unfolded. The filter screen 267 is fixedly connected to the connecting rod 265 and the vertical rod 261 on all four sides, and the bottom of the filter screen 267 is in the shape of a net bag.

[0050] In actual operation, under the action of centrifugal force, the first crossbar 262 and the second crossbar 263 unfold, thereby driving the filter screen 267 to unfold synchronously. After unfolding, the filter screen 267 is driven by the inner barrel 23 to stir the filtrate inside the outer barrel 21. During the stirring process, the filter screen 267 filters out the fine residue in the filtrate. After filtration is completed, the fine residue is put into the mesh-like filter screen 267. The first crossbar 262 and the second crossbar 263 are folded in half, causing the filter screen 267 to wrap the fine residue attached to the surface of the filter screen 267.

[0051] See Figure 6 and Figure 10 The cleaning mechanism 4 includes a sleeve 41 fixedly connected to the outside of the inner tub 23. A cavity is formed at the end of the sleeve 41 away from the inner tub 23. A sliding rod 42 is slidably connected within the cavity of the sleeve 41. A scraper 44 is fixedly connected to the end of the sliding rod 42 away from the sleeve 41. A spring 43 is installed within the cavity of the sleeve 41. One end of the spring 43 is fixedly connected to the sliding rod 42, and the other end is fixedly connected to the sleeve 41. Two sets of cleaning mechanisms 4 are provided, symmetrically installed on the outside of the inner tub 23.

[0052] In actual operation, the spring 43 pushes the slide bar 42 to drive the scraper 44 to stick tightly to the inner wall of the outer barrel 21. During the counterclockwise rotation of the inner barrel 23, the scraper 44 scrapes the filtrate and fine residue splashed onto the inner wall of the outer barrel 21 and falls to the bottom of the outer barrel 21.

[0053] See Figure 5 An agitation assembly 45 for agitating the filtrate is provided on the outside of the rotating shaft 22. The agitation assembly 45 includes a rotating disk 451 fixedly connected to the outside of the rotating shaft 22, and a plurality of stirring rods 452 fixedly connected to the outside of the rotating disk 451.

[0054] In actual operation, the rotating disk 451 drives the stirring rod 452 to stir the filtrate at the bottom of the outer barrel 21, so that the filtrate moves closer to the inner wall of the outer barrel 21 under the action of centrifugal force.

[0055] See Figure 7 The recycling mechanism 3 includes a column 31 fixedly connected to the base 1. A first guide rod 32 and a second guide rod 33 are horizontally connected through the top of the column 31. The first guide rod 32 is rotatably connected to the column 31. A knob 36 is fixedly connected to one end of the first guide rod 32. The second guide rod 33 is fixedly connected to the column 31. A threaded rod 34 is fixedly connected to the middle of the first guide rod 32. A brush plate 35 is threadedly connected to the outside of the threaded rod 34. The brush plate 35 extends downward into the inner barrel 23. The brush plate 35 is slidably connected to the second guide rod 33. A collection component 37 for cleaning the safflower residue after separation is also provided inside the inner barrel 23. Brush bristles are provided on the side of the brush plate 35.

[0056] In actual operation, the knob 36 drives the first guide rod 32 to rotate, and the threaded rod 34 in the middle of the first guide rod 32 drives the brush plate 35 to move closer to the inner wall of the inner barrel 23 along the second guide rod 33, so that the bristles on the side of the brush plate 35 are in close contact with the inner wall of the inner barrel 23. The brush plate 35 cleans off the large pieces of residue attached to the inner wall of the inner barrel 23, and the large pieces of residue that fall off collect at the bottom of the inner barrel 23.

[0057] See Figure 3 and Figure 8 The collection component 37 includes a mounting block 371 that is slidably sleeved on the outside of the first guide rod 32. The bottom of the mounting block 371 is also slidably sleeved on the outside of the second guide rod 33. A rack 374 is vertically slidably connected to the mounting block 371. A gear 373 is fixedly connected to the outside of the first guide rod 32. The gear 373 meshes with the rack 374. A collection frame 375 is fixedly connected to the bottom of the rack 374. A notch is provided on the side of the collection frame 375. Limiting blocks 372 are symmetrically fixedly connected to the first guide rod 32. The limiting blocks 372 are located on both sides of the mounting block 371. The length of the notch on the side of the collection frame 375 is greater than the inner diameter of the inner barrel 23, and one side of the notch on the side of the collection frame 375 is in contact with the inner wall of the inner barrel 23. An inverted V-shaped baffle is fixedly installed inside the collection frame 375 to reduce the probability of residue sliding out of the collection frame 375.

[0058] In actual operation, the first guide rod 32 rotates while driving the gear 373 to rotate. The gear 373 drives the rack 374 to descend. The descending rack 374 causes the collection frame 375 to contact the bottom of the inner barrel 23. Large pieces of residue that fall down collect at the bottom of the inner barrel 23. As the inner barrel 23 rotates, the large pieces of residue collected at the bottom enter the collection frame 375. The knob 36 is rotated in the opposite direction to drive the first guide rod 32 to rotate in the opposite direction. The first guide rod 32 drives the brush plate 35 to detach from the inner wall of the inner barrel 23. At the same time, the first guide rod 32 drives the rack 374 to move upward through the gear 373. Thus, the upward-moving rack 374 drives the collection frame 375, which contains large pieces of residue, to move upward. Then the collection frame 375 can be removed and the residue poured out.

[0059] Overall work process:

[0060] Step 1, Separation and Filtration: Safflower liquid is poured into the inner tank 23. The motor 25 is started, driving the rotating shaft 22 to rotate counter-clockwise. The rotating shaft 22 causes the inner tank 23 to rotate rapidly counter-clockwise. During rotation, centrifugal force throws the safflower liquid out of the separation hole 24, trapping large pieces of safflower residue inside the inner tank 23. The filtrate flows into the outer tank 21. The counter-clockwise rotation of the inner tank 23 causes the first crossbar 262 and the second crossbar 263 to rotate synchronously. Under centrifugal force, the first crossbar 262 and the second crossbar 263 unfold, thereby causing the filter screen 267 to unfold synchronously. The filter screen 267 is driven by the inner barrel 23 to agitate the filtrate inside the outer barrel 21. During the agitation, the filter screen 267 filters out the fine residue in the filtrate. The fine residue enters the mesh-like filter screen 267. After filtration, the first horizontal bar 262 and the second horizontal bar 263 are folded in half, causing the filter screen 267 to wrap the fine residue attached to its surface. Then, the vertical bar 261 is pulled to remove the filter screen 267 wrapped with fine residue from the slot 266. After removal, the fine residue attached to the surface of the filter screen 267 is cleaned off. Finally, the vertical bar 261 is reinserted into the slot 266, thereby separating the fine residue from the filtrate.

[0061] The second step is the cleaning process: Under the elastic force of the spring 43, the slide bar 42 drives the scraper 44 to stick tightly to the inner wall of the outer barrel 21. During the counterclockwise rotation of the inner barrel 23, the scraper 44 scrapes the filtrate and small residues splashed onto the inner wall of the outer barrel 21 and scrapes them off to the bottom of the outer barrel 21. At the same time, the rotating disc 451 drives the stirring rod 452 to stir the filtrate at the bottom of the outer barrel 21, so that the filtrate moves closer to the inner wall of the outer barrel 21 under the action of centrifugal force, and thus the small residues in the filtrate can be filtered out by the filter screen 267.

[0062] The third step is to collect the residue: Larger pieces of residue remaining in the inner tub 23 need to be removed. At this point, turning the knob 36 rotates the first guide rod 32. The threaded rod 34 in the middle of the first guide rod 32 drives the brush plate 35 along the second guide rod 33 towards the inner wall of the inner tub 23, so that the bristles on the side of the brush plate 35 are tightly against the inner wall of the inner tub 23. Simultaneously, the rotation of the first guide rod 32 drives the gear 373 to rotate, which in turn drives the rack 374 to descend. The descending rack 374 causes the collection frame 375 to contact the bottom of the inner tub 23. Then, the motor 25 is started, causing the inner tub 23 to rotate clockwise. The clockwise rotation of the inner tub 23, through the brush… The plate 35 cleans off the large pieces of residue adhering to the inner wall of the inner bucket 23. The large pieces of residue that fall off collect at the bottom of the inner bucket 23. As the inner bucket 23 rotates, the large pieces of residue collected at the bottom enter the collection frame 375, thereby cleaning the large pieces of residue inside the inner bucket 23. Finally, the knob 36 is rotated in the opposite direction to drive the first guide rod 32 to rotate in the opposite direction. The first guide rod 32 drives the brush plate 35 to detach from the inner wall of the inner bucket 23. At the same time, the first guide rod 32 drives the rack 374 to move upward through the gear 373. This upward movement of the rack 374 drives the collection frame 375, which contains large pieces of residue, to move upward. The collection frame 375 can then be removed to empty the residue.
